Laparoscopic total gastrectomy for a giant gastrointestinal stromal tumor (GIST) with acute massive gastrointestinal bleeding: a case report.

Abstract

Gastrointestinal stromal tumors (GISTs) include 80% of gastrointestinal mesenchymal tumors that originate from interstitial Cajal cells and include 0.1–3% of GI malignancies, and the stomach is the most commonly involved organ. The only potentially curative treatment is surgical resection with clear margins. Although laparoscopic resection of small GISTs is a standard treatment, there is controversy about laparoscopic surgical resection for large and giant GISTs. A 52-year-old woman, a known case of large GIST of the stomach that was under neoadjuvant imatinib therapy, was admitted to the emergency department due to acute massive gastrointestinal bleeding (GIB). The patient underwent laparoscopic total gastrectomy and received adjuvant imatinib after surgery. Laparoscopic resection is a safe and feasible method in large and giant GISTs with oncologic and long-term outcomes comparable to open surgery, and with better short-term outcomes.
