Other Complicated Surgeries

Gastrointestinal, Pancreatic, Hepatobiliary Surgery

Research shows that major complications and mortality risks are lower are lower when performed by Surgeons who carry out a high volume of complicated gastrointestinal, pancreatic and hepatobiliary surgeries like minimally invasive and open liver resections or Whipple procedures for pancreatic cysts and tumors.

That's why choosing the correct surgeon for surgery could be the most important decision you ever make. Each year, the team of surgeons lead by Dr. Sanjoy Mandal, performs thousands of surgical procedures involving the esophagus, stomach, duodenum, liver, gallbladder, bile ducts, pancreas and intestine. Our gastrointestinal, pancreatic and hepatobiliary surgeons work closely with other divisions of Gastroenterology, Diagnostic and Interventional Radiology and Nuclear Medicine to provide a team approach designed to meet each patient's individual needs.

Key Highlights

  • Innovative surgical approaches for benign and malignant esophageal disease.
  • Minimally-invasive laparoscopic approaches for gastric, pancreatic and liver resection when appropriate.
  • Integrative therapy including surgical resection, radiofrequency ablation, radioembolization, chemoembolization, and cryotherapy for liver tumors.


  • Shunt Surgery: Proximal spleenorenal shunt (PSRS) also called lienorenal shunt (LR Shunt): in this procedure the spleen is removed and communication is created between the spleenic vein and renal vein. This leads to decrease in pressure in the portal vein and hence stops the bleeding.
  • Spleenectomy and Devascularization: In this procedure the spleen is removed and the veins along the stomach and esophagus is meticulously tied. This ultimately prevents the bleeding.
  • Corrosive injury of the esophagus: These are patients who present with dysphagia or inability to swallow following acid or alkali ingeation. Here the obstructed esophagus is bypassed with a long segment of colon (large bowel). Some of these patients may require a temporary tracheostomy (tube in the wind pipe) and long term swallowing therapy.
  • Chronic pancreatitis: Frey's procedure which involves removing part of the head of the pancreas and bypassing the rest. In some other cases a Whipple's operation maybe required.
  • Ulcerative colitis: Surgery for ulcerative colitis is performed only for those patients who are not responding to medical treatment. This involves removal of whole of the colon and rectum, making a pouch of the small intestine and attaching it to the anal canal so as to restore the bowel continuity. These patients may require a temporary stoma. This is usually done in 2 or 3 stages.
  • Crohn's disease: Most patient of crohn's disease do not require surgery. But some who have recurrent bouts of obstruction, bleeding, perforation or have a persisting doubt in diagnosis will require surgery.
  • Post cholecystectomy problems: cholecystectomy is a very simple and common procedure. Most patients do not have complications but a very few can have complications which can life threatening. Inspite of the best possible care and precautions such complications can happen and that too in the best possible hands. Management of such problems is difficult. All the more most such patients are young and in the prime of their life. Intervention that is required in these cases range from endoscopy and stenting (ERCP) to major surgery. Surgery can be just drainage of bile or definite repair of bile duct stricture (Roux-en-Y hepaticojejunostomy).
  • Complex and High Anal fistulas: Fistulectomy with mucosal flap advancement, seton drainage, anal plug placement and VAAFT (Video assisted anal fistula treatment).
