Two potential post-operative complications of pancreatic surgery are pancreatic leak and diabetes. Pancreatic leaks are not always avoidable, but are best managed by an experienced pancreatic surgeon. Uncontrolled pancreatic leaks may be life-threatening, and result in fever, abdominal abscess and wound problems. Some patients may develop diabetes after pancreatic surgery. This will depend on the extent of surgery, and may occur after Whipples surgery (where most of the insulin-producing cells are located).
