Laparoscopic sleeve gastrectomy for a large gastrointestinal stromal tumor.

The biological behavior of gastrointestinal stromal tumor (GIST) makes resection of the tumor with adequate margins, a mode of curative treatment. GIST does not have lymphatic permeation. Hence, the goal of therapy is complete resection of visible and microscopic disease, which can be achieved by adequate tumor-free margins.

Minimally invasive approach to pancreatic necrosectomy.

Background: Conventional open surgery for infected pancreatic necrosis is associated with significant surgical morbidity, that is, wound complications, facial dehiscence, and intestinal fistulae. In recent years, there has been interest in attempting to reduce this surgical morbidity by adopting a number of minimally invasive approaches.

Methods: Fifteen patients with pancreatic necrosis underwent pancreatic necrosectomy by minimally invasive surgery (11 men, 4 women; age group: 25-64 years, mean age: 46 years).
