Pancreas

Acute or Chronic Pancreatitis



Introduction

The pancreas is a gland behind the stomach and in front of the spine. It produces juices that help break down food and hormones that help control blood sugar levels. In type 1 diabetes, the beta cells of the pancreas no longer make insulin because the body's immune system has damaged the insulin producing cells of pancreas. In type 2 diabetes, the pancreas loses the ability to secrete enough insulin in response to meals.

The pancreas can lead to many health problems. These include

  •   Pancreatitis, or inflammation of the pancreas: This happens when digestive enzymes start digesting the pancreas itself. It may be acute or chronic or recurrent.
  •   Calcific Chronic Pancreatitis
  •   Pancreatic cancer

Risk Factor

The most common cause of acute pancreatitis is alcohol intake or stones in the gallbladder. Other known causes are high triglyceride levels in the blood, high calcium levels in the blood. In some cases, cause remains uncertain despite proper investigations.

Symptoms

Acute pancreatitis usually begins with gradual or sudden pain in the upper abdomen that sometimes extends to the back. The pain may be mild at first and become worse after eating. The pain is often severe, constant, and commonly lasts for several days in the absence of treatment. Most of cases of acute mild pancreatitis are milder in severity ie. doesn’t have any organ damage.

Diagnosis

Clinical symptoms are suggestive of acute pancreatitis. Blood tests are done to confirm the diagnosis. Ultrasound is advised to look for stones in gallbladder or in bile duct as a cause of acute pancreatitis. Ultrasound also assess extend of damage to pancreas, but it may be normal in initial 2-3 days despite clinical symptoms and positive blood reports. Doctors take decision after considering all points. Sometimes CECT of pancreas is advised, if there is doubt in diagnosis, or some of the complications of acute pancreatitis are suspected.

Complications

Acute Pancreatitis

  •   Acute Fluid Collections
  •   Pancreatic and Peripancreatic Necrosis
  •   Pancreatic Abscess and Infected Pancreatic Necrosis
  •   Pancreatico-enteric fistula
  •   Aneurysm

Chronic Pancreatitis

  •   Pancreatic Pseudocyst
  •   Pancreatic Ascitis
  •   Pancreatico-pleural fistula
  •   Splenic Vein Throsmosis
Treatment

Patient is advised admission and kept under observation as few cases may progress to severe form of pancreatitis despite best medical treatment. Such cases are shifted to ICU for further treatment and daily monitoring is done to assess whether complications are evolving or resolving. Based upon type of complications, there are variety of approach to manage the complications. It may be endoscopic therapy / radiological therapy / laparosocopic surgery or open surgery. The team of expert like endoscopist, interventional radiologist, Intensivist & surgeon decide the appropriate approach for treatment for given situation.

Few patients recover from complications of acute pancreatitis and manifest in due course with another set of complications. The specific complication is treated with best possible approach. Surgery approach for complications of acute or chronic pancreatitis includes necrosectomy, abscess drainage, internal drainage of chronic pseudocyst. Surgical approach for calcific chronic pancreatitis includes drainage procedure like Partington and Rochelle Lateral pancreatico-jejunostomy, Begers Procedure & resectional procedure if disease is localised in distal part pancreas.

Calcific Chronic Pancreatitis



Introduction

Chronic calcifying/calcific pancreatitis (CCP) is a special form of chronic pancreatitis that is associated with pancreatic stones.

This is also known as Tropical calcific pancreatitis (TCP) as it occurs in children and young adults in tropics and has features that distinguish it from alcoholic calcific pancreatitis (ACP) seen in developed countries of the subtropics. In India, it’s very common in southern part but also seen in other northern & western India.
Risk Factor

Malnutrition, food toxins, deficiency of micronutrients and recently genetic factors are considered the underlying cause of this disease.

Symptoms

The main symptoms were abdominal pain, diabetes mellitus, weight loss, obstructive jaundice and steatorrhea (oily stool). Abdominal pain may be episodic or unrelenting pain that is not relieved by drugs and warranted therapy. On the other hand, patients may experience pain-free episodes for years due to significant damage to pancreas. Some patients may present as uncontrolled diabetes or stool looks like oily and it float over pot despite flush. Both symptoms suggest that damage to pancreas so extensive it doesn’t sufficient enzymes for digestion of food.

Diagnosis

There are no specific blood test. X-ray or Ultrasonography may shows stones in pancreas. CECT pancreas is advised to assess the location of stones and their load and other complications. MRCP is advised if jaundice is also associated.

Complications

If untreated for long term, following complications may develop

  •   Cyst
  •   Cyst with Infection
  •   Cyst with bleeding (Pseudoaneurysm)
  •   Pancreatic Ascites or Effusion
  •   Pancreatico-pleural fistula
  •   Splenic Vein Thrombosis
  •   Cancer
Treatment

Low fat diet, simple pain killer and supplementation of pancreatic enzyme is initial treatment. Endoscopic therapy is advised there is a single stone and pancreatic duct is dilated. Surgery is advised when there is multiple stones in pancreas, narrowing of pancreatic duct at multiple level or presence of complications. Surgical approach for calcific chronic pancreatitis includes drainage procedure or resectional procedure. This decision is based upon the extend of pancreatic disease.



PANCREAS



Introduction

The pancreas is an organ that is about 6 inches long. It’s located deep in your belly between your stomach and backbone. Your liver, intestine, and other organs surround your pancreas.

The widest part of the pancreas is called the head. The head of the pancreas is closest to the small intestine. The middle section is called the body, and the thinnest part is called the tail.

The pancreas makes pancreatic juices. These juices contain enzymes that help break down food. The juices flow through a system of ducts leading to the main pancreatic duct. The pancreatic juices flow through the main duct to the duodenum, the first part of the small intestine.

The pancreas is also a gland that makes insulin and other hormones. These hormones enter the bloodstream and travel throughout the body. They help the body use or store the energy that comes from food. For example, insulin helps control the amount of sugar in the blood.


This picture shows the pancreas and nearby organs.


Cancer Cells

Cancer begins in cells, the building blocks that make up tissues. Tissues make up the pancreas and the other organs of the body.

Normal cells grow and divide to form new cells as the body needs them. When normal cells grow old or get damaged, they die, and new cells take their place.

Sometimes, this process goes wrong. New cells form when the body doesn’t need them, and old or damaged cells don’t die as they should. The buildup of extra cells often forms a mass of tissue called a growth or tumor.


This picture shows the head, body, and tail of the pancreas.

Benign tumors (such as cysts):

  1. are usually not a threat to life
  2. can be removed and usually don’t grow back
  3. don’t invade the tissues around them
  4. don’t spread to other parts of the body

Malignant growths:

  1. may be a threat to life
  2. sometimes can be removed but can grow back
  3. can invade and damage nearby tissues and organs
  4. can spread to other parts of the body

Pancreatic cancer can invade other tissues, shed cancer cells into the abdomen, or spread to other organs:

  1. Invade: A malignant pancreatic tumor can grow and invade organs next to the pancreas, such as the stomach or small intestine.
  2. Shed: Cancer cells can shed (break off) from the main pancreatic tumor. Shedding into the abdomen may lead to new tumors forming on the surface of nearby organs and tissues. The doctor may call these seeds or implants. The seeds can cause an abnormal buildup of fluid in the abdomen (ascites).
  3. Spread: Cancer cells can spread by breaking away from the original tumor. They can spread through the blood vessels to the liver and lungs. In addition, pancreatic cancer cells can spread through lymph vessels to nearby lymph nodes. After spreading, the cancer cells may attach to other tissues and grow to form new tumors that may damage those tissues.
Risk Factor

When you get a diagnosis of cancer, it’s natural to wonder what may have caused the disease. Doctors can’t always explain why one person gets pancreatic cancer and another doesn’t. However, we do know that people with certain risk factors may be more likely than others to develop cancer of the pancreas. A risk factor is something that may increase the chance of getting a disease.

Studies have found the following risk factors for cancer of the pancreas:

  1. Smoking: Smoking tobacco is the most important risk factor for pancreatic cancer. People who smoke tobacco are more likely than nonsmokers to develop this disease. Heavy smokers are most at risk.
  2. Diabetes: People with diabetes are more likely than other people to develop pancreatic cancer.
  3. Family history: Having a mother, father, sister, or brother with pancreatic cancer increases the risk of developing the disease.
  4. Inflammation of the pancreas: Pancreatitis is a painful inflammation of the pancreas. Having pancreatitis for a long time may increase the risk of pancreatic cancer.
  5. Obesity: People who are overweight or obese are slightly more likely than other people to develop pancreatic cancer.

Many other possible risk factors are under active study. For example, researchers are studying whether a diet high in fat (especially animal fat) or heavy drinking of alcoholic beverages may increase the risk of pancreatic cancer. Another area of active research is whether certain genes increase the risk of disease.

Many people who get pancreatic cancer have none of these risk factors, and many people who have known risk factors don’t develop the disease.

Symptoms

Early cancer of the pancreas often doesn’t cause symptoms. When the cancer grows larger, you may notice one or more of these common symptoms:

  •   Dark urine, pale stools, and yellow skin and eyes from jaundice
  •   Pain in the upper part of your belly
  •   Pain in the middle part of your back that doesn’t go away when you shift your position
  •   Nausea and vomiting
  •   Stools that float in the toilet

Also, advanced cancer may cause these general symptoms:

  •   Weakness or feeling very tired
  •   Loss of appetite or feelings of fullness
  •   Weight loss for no known reason

These symptoms may be caused by pancreatic cancer or by other health problems. People with these symptoms should tell their doctor so that problems can be diagnosed and treated as early as possible.

Diagnosis

If you have symptoms that suggest cancer of the pancreas, your doctor will try to find out what’s causing the problems.

You may have blood or other lab tests. Also, you may have one or more of the following tests:

  1. Physical exam: Your doctor feels your abdomen to check for changes in areas near the pancreas, liver, gallbladder, and spleen. Your doctor also checks for an abnormal buildup of fluid in the abdomen. Also, your skin and eyes may be checked for signs of jaundice.
  2. CT scan: An x-ray machine linked to a computer takes a series of detailed pictures of your pancreas, nearby organs, and blood vessels in your abdomen. You may receive an injection ofcontrast material so your pancreas shows up clearly in the pictures. Also, you may be asked to drink water so your stomach and duodenum show up better. On the CT scan, your doctor may see a tumor in the pancreas or elsewhere in the abdomen.
  3. Ultrasound: Your doctor places the ultrasound device on your abdomen and slowly moves it around. The ultrasound device uses sound waves that can’t be heard by humans. The sound waves make a pattern of echoes as they bounce off internal organs. The echoes create a picture of your pancreas and other organs in the abdomen. The picture may show a tumor or blocked ducts.
  4. EUS: Your doctor passes a thin, lighted tube (endoscope) down your throat, through your stomach, and into the first part of the small intestine. An ultrasound probe at the end of the tube sends out sound waves that you can’t hear. The waves bounce off tissues in your pancreas and other organs. As your doctor slowly withdraws the probe from the intestine toward the stomach, the computer creates a picture of the pancreas from the echoes. The picture can show a tumor in the pancreas. It can also show how deeply the cancer has invaded the blood vessels.

Some doctors use the following tests also:

  1. ERCP: The doctor passes an endoscope through your mouth and stomach, down into the first part of your small intestine. Your doctor slips a smaller tube through the endoscope into the bile ducts and pancreatic ducts. (See picture of ducts.) After injecting dye through the smaller tube into the ducts, the doctor takes x-ray pictures. The x-rays can show whether the ducts are narrowed or blocked by a tumor or other condition.
  2. MRI: A large machine with a strong magnet linked to a computer is used to make detailed pictures of areas inside your body.
  3. PET scan: You’ll receive an injection of a small amount of radioactive sugar. The radioactive sugar gives off signals that the PET scanner picks up. The PET scanner makes a picture of the places in your body where the sugar is being taken up. Cancer cells show up brighter in the picture because they take up sugar faster than normal cells do. A PET scan may show a tumor in the pancreas. It can also show cancer that has spread to other parts of the body.
  4. Needle biopsy: The doctor uses a thin needle to remove a small sample of tissue from the pancreas. EUS or CT may be used to guide the needle. A pathologist uses a microscope to look for cancer cells in the tissue.
Staging

After extrahepatic bile duct cancer has been diagnosed, tests are done to find out if cancer cells have spread within the bile duct or to other parts of the body. The process used to find out if cancer has spread within the extrahepatic bile duct or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease. It is important to know the stage in order to plan treatment.

Extrahepatic bile duct cancer may be staged following a laparotomy. A surgical incision is made in the wall of the abdomen to check the inside of the abdomen for signs of disease and to remove tissue andfluid for examination under a microscope. The results of the diagnostic imaging tests, laparotomy, andbiopsy are viewed together to determine the stage of the cancer. Sometimes, a laparoscopy will be done before the laparotomy to see if the cancer has spread. If the cancer has spread and cannot be removed by surgery, the surgeon may decide not to do a laparotomy.

There are three ways that cancer spreads in the body.

The three ways that cancer spreads in the body are:

  1. Through tissue. Cancer invades the surrounding normal tissue.
  2. Through the lymph system. Cancer invades the lymph system and travels through the lymph vessels to other places in the body.
  3. Through the blood. Cancer invades the veins and capillaries and travels through the blood to other places in the body.

When cancer cells break away from the primary (original) tumor and travel through the lymph or blood to other places in the body, another (secondary) tumor may form. This process is called metastasis. The secondary (metastatic) tumor is the same type of cancer as the primary tumor. For example, ifbreast cancer spreads to the bones, the cancer cells in the bones are actually breast cancer cells. The disease is metastatic breast cancer, not bone cancer.

There are two staging systems for extrahepatic bile duct cancer.

Extrahepatic bile duct cancer has two staging systems. The staging system used depends on where in the extrahepatic bile duct the cancer first formed.

  1. Perihilar or proximal extrahepatic bile duct tumors (perihilar bile duct tumors) form in the area where the bile duct leaves the liver. This type of tumor is also called a Klatskin tumor.
  2. Distal extrahepatic bile duct tumors (distal bile duct tumors) form in the area where the bile duct empties into the small intestine.

The following stages are used for perihilar extrahepatic bile duct cancer:

Stage 0 (Carcinoma in Situ)

In stage 0, abnormal cells are found in the innermost layer of tissue lining the perihilar bile duct. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ.

Stage I

In stage I, cancer has formed in the innermost layer of the wall of the perihilar bile duct and has spread into the muscle and fibrous tissue of the wall.

Stage II

In stage II, cancer has spread through the wall of the perihilar bile duct to nearby fatty tissue or to theliver.

Stage III

Stage III is divided into stages IIIA and IIIB.

  1. Stage IIIA: The tumor has spread to one branch of the hepatic artery or of the portal vein (vesselsthat carry blood to and from the liver).
  2. Stage IIIB: The tumor has spread to nearby lymph nodes. Cancer has also spread into the wall of the perihilar bile duct and may have spread through the wall to nearby fatty tissue, the liver, or to one branch of the hepatic artery or of the portal vein (vessels that carry blood to and from the liver).

Stage IV

Stage IV is divided into stages IVA and IVB.

  1. Stage IVA: The tumor may have spread to nearby lymph nodes and has spread to one or more of the following:
  2. the main part of the portal vein (a vessel that carries blood away from the liver) or both branches of the portal vein;
  3. the hepatic artery (a vessel that carries blood to the liver);
  4. the right and left hepatic ducts;
  5. the right hepatic duct and the left branch of the hepatic artery or of the portal vein;
  6. the left hepatic duct and the right branch of the hepatic artery or of the portal vein.
  7. Stage IVB: The tumor has spread to other parts of the body, such as the liver.

The following stages are used for distal extrahepatic bile duct cancer:

Stage 0 (Carcinoma in Situ)

In stage 0, abnormal cells are found in the innermost layer of tissue lining the distal bile duct. These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ.

Stage I

In stage I, cancer has formed. Stage I is divided into stages IA and IB.

  1. Stage IA: Cancer is found in the distal bile duct only.
  2. Stage IB: Cancer has spread all the way through the wall of the distal bile duct.

Stage II

Stage II is divided into stages IIA and IIB.

  1. Stage IIA: Cancer has spread from the distal bile duct to the gallbladder, pancreas, small intestine, or other nearby organs.
  2. Stage IIB: Cancer has spread from the distal bile duct to nearby lymph nodes. Cancer may have spread through the wall of the distal bile duct or to the gallbladder, pancreas, small intestine, or other nearby organs.

Stage III

  1. In stage III, cancer has spread to the large vessels that carry blood to the organs in the abdomen. Cancer may have spread to nearby lymph nodes.

Stage IV

  1. In stage IV, cancer has spread to other parts of the body, such as the liver or lungs.
Treatment

Depending on your cancer type and stage, our goals for treatment are:

  1. Cure : This is the most important goal of cancer surgery. In fact as a cancer patient you are also strongly willing to have cure of cancer for forever. For most of the Liver & Gastro-intestinal cancers perhaps surgery is the first step for cure. Radiation &/or Chemotheray may be advised as an additional tool to achieve this goal.
  2. Control : If your cancer is at a later stage or if previous treatments have been unsuccessful, we aim to control your cancer by removing as much as safely possible. Once you recover from surgery, radiation or chemotherapy is advised as important tool to control your cancer.
  3. Comfort : If you have an advanced stage of cancer or one that hasn't responded to treatments and having symptoms because of tumor i.e pain, jaundice, vomiting, bleeding either in vomitus or in stool, then our multi-specialist team work together to sure you are free of pain and other symptoms.
Role of Surgery for Cancer treatment

Surgery can be done for many reasons for treatment of cancer.

Curative Surgery
  1. Curative surgery is done when cancer is found in only one area, and it’s likely that all of the cancer can be removed. In this case, curative surgery can be the main treatment. It may be used alone or along with chemotherapy or radiation therapy, which can be given before or after the operation.
Diagnostic & Staging Surgery
  1. This type of surgery is used to take out a piece of tissue (biopsy) to find out if cancer is present or what type of cancer it is. The diagnosis of cancer is made by looking at the cells under a microscope. Staging surgery is done to find out how much cancer there is and how far it has spread. The physical exam and the results of lab and imaging tests are used to figure out the clinical stage of the cancer. But the surgical stage (also called the pathologic stage) is usually a more exact measure of how far the cancer has spread. Examples of surgical procedures commonly used to stage cancers, like laparoscopy or laparotomy.
Palliative Surgery
  1. This type of surgery is used to treat problems caused by advanced cancer. It is not done to cure the cancer. For example, cancers of intestine may grow large enough to block off (obstruct) the intestine, or tumor is bleeding and unable to control bleed by medical/endoscopic technique. If this happens, surgery can be used to remove the blockage/control bleeding.


Approach for Surgery:

How surgery is performed? (Special surgery techniques): Open Or Laparoscopic

Open Surgery:
  1. It is the Gold Standard approach for Liver & Gastro-Intestinal cancer. An incision is given on the belly depending upton the underlying location of tumor so that surgeon can directly approach the cancer on cutting the belly. Open Surgery help to remove tumor safely if its adherent to near by blood vessels or organ, that is otherwise difficult in laparoscopic surgery.
Laparoscopic Surgery
  1. A laparoscope is a long, thin, flexible tube that can be put through a small cut (incision) to look inside the body. In recent years, doctors have found that by creating small holes and using special instruments, the laparoscope can be used to perform surgery without making a large cut. This can help reduce blood loss during surgery and pain afterward. It can also shorten hospital stays and allow people to heal faster.
  2. The role of laparoscopic surgery in cancer treatment is not yet clear. Doctors are now studying whether it is safe and effective to use laparoscopic surgeries for cancers of the stomach, colon, rectum & liver. It may prove to be as safe and work as well as standard surgery while cutting less and causing less damage to healthy tissues (being less invasive).


Biopsy of Cancer before Surgery

Biopsy is procedure to confirm the presence of cancer. It’s not essential before surgery. Usually biopsy is performed when 1. Suspicion is cause other than cancer, 2. When surgery cannot be done for cancer due to advanced stage of cancer or 3. Patient is unfit to undergo surgery. In these situation, biopsy guides for further therapy.

If all investigations suggest that cancer can be removed in totality from body, then biopsy can be avoided in to minimize the risk of spillage of cancer cell during biopsy procedure.

There is variety of way to perform biopsies:

Fine Needle Aspiration (FAN) biopsy
  1. Fine needle aspiration (FNA) uses a very thin needle attached to a syringe to pull out small bits of tissue. The needle is guided into the tumor by looking at it using an imaging test, like an ultrasound or CT scan.
  2. The main advantage of FNA is that there is no need to cut through the skin, so there is no surgical incision.
  3. A drawback is that in some cases the needle can’t take out enough tissue for an exact diagnosis. A more invasive type of biopsy (one that involves larger needles or a cut in the skin) may then be needed.
Core Needle biopsy
  1. This type of biopsy uses a larger needle to take out a core of tissue and done under guidance of imaging test like an ultrasound or CT scan. The advantage of core biopsy is that it usually collects enough tissue to find out whether the tumor is cancer.
Excisional or Incisional biopsy
  1. For these biopsies, the surgeon remove the entire tumor (excisional biopsy) or a small part of the tumor (incisional biopsy).

Preparation for Surgery

Our expert team members shall help you to prepare you for surgery. You are strongly advised to stop smoking, stop drinking alcohol, try to improve your diet, lose weight, or actively exercise before surgery.

Pre-operative testing

In most cases, you will need some tests before your surgery. The tests routinely used include:

  1. Blood tests to measure your blood counts, your risk of bleeding or infection, and how well your liver and kidneys are working. Your blood group type is also be checked in case you need blood transfusions during the operation.
  2. Chest x-ray and ECG (electrocardiogram) to check your lungs and your heart’s electrical system.
  3. USG/CT scans/ MRI to look at the size and location of the tumors and see if the cancer looks like it has spread to nearby tissues.
Anaesthetic Assessment before Surgery:

Our expert team of Anaesthetist will ask you questions pertaining to your health and to assess your fitness for surgery. You are requested to tell them in detail about your current and past medical ailments, allergic reactions you’ve had in the past and current medicines that you are taking like blood thinning medicine. This medicine should be stopped 1 week prior to surgery.

Informed Consent

Informed consent is one of the most important parts of “getting ready for surgery”. It is a process during which you are told about all aspects of the treatment before you give your doctor written permission to do the surgery.

Getting ready for Surgery

Depending on the type of operation you have, there may be things you need to do to be ready for surgery:

  1. Emptying your stomach and bowels (digestive tract) is important. Vomiting while under anaesthesia can be very dangerous because the vomit could get into your lungs and cause an infection. Because of this, you will be asked to not eat or drink anything starting the night before the surgery.
  2. Laxative: You may also be asked to use a laxative or an enema to make sure your bowels are empty.
  3. Shaving of Operative part: You need to have an area of your body shaved to keep hair from getting into the surgical cut (incision). The area will be cleaned before the operation to reduce the risk of infection.
Anaesthesia

Anaesthesia is the use of drugs to make the body unable to feel pain for a period of time. General anaesthesia puts you into a deep sleep for the surgery. It is often started by having you breathe into a face mask or by putting a drug into a vein in your arm. Once you are asleep, an endotracheal or ET tube is put in your throat to make it easy for you to breathe. Your heart rate, breathing rate, and blood pressure (vital signs) will be closely watched during the surgery. A doctor watches you throughout the procedure and until you wake up. They also take out the ET tube when the operation is over. You will be taken to the recovery room to be watched closely while the effects of the drugs wear off. This may take hours. People waking up from general anaesthesia often feel "out of it" for some time. Things may seem hazy or dream-like for a while. Your throat may be sore for a while from the endotracheal (ET) tube.


Recovery from Surgery

Your recovery right after surgery depends on many factors, including your state of health before the operation and how extensive the operation was performed.

Pain

You may feel pain at the site of surgery. We aim to keep you pain free after surgery with the help of latest and most effective technique or analgesic (pain relieving medicine).

Tube/ Drains
  1. You may also have Ryle’s Tube (tube going through nose to stomach) that drain out intestinal fluid. This tube helps to relieve nausea and vomiting after surgery and usually removed 1-2 day after surgery.
  2. You may also have “Tube” (called a Foley catheter) draining urine from your bladder into a bag. This will be taken out soon after surgery, once you are comfortable enough to go to bathroom.
  3. You may have a tube or tubes (called Drains) coming out of the surgical opening in your skin (incision site). Drains allow the excess fluid that collects at the surgery site to leave the body. Drain tube will also be removed once they stop collecting fluid, usually a few days after the operation.
Leg Stocking / Compression boot

As you are remains in bed on day of surgery, circulation of blood in leg become sluggish that may increase possibility of thrombo-embolism. To minimise it, you will be wearing leg stocking/ pneumatic compression boot to improve your leg circulation thus minimising the risk of thrombolism.

Eating and Drinking

You may not feel much like eating or drinking, but this is an important part of the recovery process. Our health care team may start you out with ice chips or clear liquids. The stomach and intestines (digestive tract) is one of the last parts of the body to recover from the drugs used during surgery. You will need to have signs of stomach and bowel activity before you will be allowed to eat. You will likely be on a clear liquid diet until this happens. Once it does, you may get to try solid foods.

Activity
  1. Our health care team will try to have you move around as soon as possible after surgery. They may even have you out of bed and walking the same day. While this may be hard at first, it helps speed your recovery by getting your digestive tract moving. It also helps your circulation and helps prevent blood clots from forming in your legs.
  2. Our team shall also encourage you to do deep breathing exercises. This helps fully inflate your lungs and reduces the risk of pneumonia. You are advised to take deep breaths and cough every hour to help prevent lung infections. You will use an incentive spirometer (a small device used in breathing exercises to prevent complications after major surgery) 10-15 times every hour.
Going home

Once you are eating and walking, all tube/drains placed during surgery are removed, and then you may be ready to go home. Before leaving for home our health care team shall give you detailed guidance regarding diet, activities, medications & further plan of treatment.

Risks and side effects of surgery

There are risks that go with any type of medical procedure and surgery is no longer an exception. Success of surgery depends upon 3 factors: type of disease/surgery, experience of surgeon and overall health of patients. What’s important is whether the expected benefits outweigh the possible risks.

Doctors have been performing surgeries for a very long time. Advances in surgical techniques and our understanding of how to prevent infections have made modern surgery safer and less likely to damage healthy tissues than it has ever been. Still, there’s always a degree of risk involved, no matter how small. Different procedures have different kinds of risks and side effects. Be sure to discuss the details of your case with our health care team, who can give you a better idea about what your actual risks are. During surgery, possible complications during surgery may be caused by the surgery itself, the drugs used (anesthesia), or an underlying disease. Generally speaking, the more complex the surgery is the greater the risk. Complications in major surgical procedures include:


  1. Complications related to Anaesthesia : Reactions to drugs used (anesthesia) or other medicines. Although rare, these can be serious because they can cause dangerously low blood pressures. Your doctors will watch your heart rate, breathing rate, blood pressure, and other signs throughout the procedure to look for this.
  2. Complications related to underlying medical illness like heart disease, diabetes, kidney disease, obesity, malnutrition.
    1. Lung : Pneumonia, Atelectasis (collapse of lung), effusion (fluid in chest) can occur, especially in patients with reduced lung function, such as smokers. Doing deep breathing exercises as soon as possible after surgery helps lessen this risk.
    2. Thrombosis (blood clot) in leg & embolism (blood clot) in lung : Blood clots can form in the deep veins of the legs after surgery, especially if a person stays in bed for a long time. Such a clot can become a serious problem if it breaks loose and travels to another part of the body, such as a lung. This is a big reason why you will be encouraged to get out of bed to sit, stand, and walk as soon as possible.
    3. Cardiovascular : Myocardial infarction (heart attach), Arrhythmia (irregular heart beat), Stroke (cerebro-vascular accidents).
    4. Kidney & urinary tract infection, acute kidney failure if patient has uncontrolled/non-responding infection.
  3. Complications related to Specific Operations
    1. There are specific complications related to type of surgery. You are encouraged with discuss in detail with our health care team before you give your consent for surgery.
    2. Bile leak
    3. Bleed
  4. Complications related to Major Surgery
    1. Infection : Infection at the site of the wound, lung and urinary infection. Infection risk is more if intestine is perforated before surgery, operated for colon and rectum, stent in placed in bile duct to relieve jaundice or intestinal joint is leaking.
    2. Bleeding : The risk of bleeding during or after surgery is more if patient taking blood thinning medicine till day of surgery or having liver dysfunction. Bleeding during surgery that may cause you to need blood transfusions. There is a risk of certain problems with transfusions, some of them serious. Still, some operations involve a certain amount of controlled blood loss. Bleeding can happen either inside the body (internally) or outside the body (externally). It can occur if a blood vessel sealed during surgery opens up or if a wound opens up. Serious bleeding may cause the person to need another operation to find the source of the bleeding and stop it.
    3. Leakage from anastomosis (joint of anastomosis) & fluid collection in tummy.
    4. Blockage of intestine (Intestinal obstruction)
Supportive Care

Pain Control

Cancer of the pancreas and its treatment may lead to pain. Your doctor or a specialist in pain control can suggest ways to relieve or reduce pain. You may want to ask if your hospital has a palliative care team.

There are many ways to relieve or reduce pain:

  1. Pain medicine: Your health care team can suggest medicines that will relieve pain. If you have constipation or other side effects from the medicine, your health care team will help you manage the problems.
  2. Nerve block: The doctor may inject alcohol into the area around certain nerves in the abdomen to block the pain.
Blockage

If the tumor in the pancreas grows large enough to squeeze the common bile duct or block the duodenum, your health care team can suggest ways to help:

  1. Surgery: The surgeon can create a bypass through the blocked bile duct or duodenum. A bypass allows fluids to flow through the digestive tract. It can help relieve jaundice and pain resulting from the blockage.
  2. Stent: The doctor uses an endoscope to place a stent in the blocked area. A stent is a tiny plastic or metal mesh tube that helps keep the duct or duodenum open.
Life After Surgery

Follow up care
  1. You'll need regular check-ups after treatment for liver cancer. This help to find out any change in your recovery. Sometimes liver cancer comes back after treatment. Our health care team will check for return of cancer. Checkups may include a physical exam, blood tests, ultrasound / CT scan.
  2. If you have any health problems between checkups, you should contact our health care team. Report to our health care team, if you have any redness/ swelling or discharge of any type of fluid from your operative incision site, pain abdomen, vomiting or fever, breathing difficulty etc.
