Laparoscopy: Small Incisions, Major Surgeries

People rarely get a single organ disease so that the concerned specialist may operate on the part and cure the patient. Most patients have multiple organ problems, and treating them during a single surgery is possible when a team of different specialists work together to achieve relief and comfort for the patient. GI surgeon Dr Avinash Tank removed Gall Stones, Urologists Dr C P Garg and Dr Kartik Shah removed a kidney which had a tumour, in a single surgical procedure with small incisions. Needless to mention that this was possible only because of the full support of the the operating room and the ward staff nurses...!

Bariatric Surgery: Hope for the Obese

Being overweight is bad, being obese is worse, but being morbidly obese is the worst! Morbid obesity is defined as as a person whose BMI is more than 35. BMI is calculated as weight in kg divided by height in metres squared. While an overweight person may aim to reduce his weight, a morbidly obese person may not be able to reduce weight. Bariatric Surgery is treatment to reduce weight. We present the case of Mr Hemant Korawala, who weighed 139 kg at the hands of GI surgeon Dr Avinashkumar Tank.
