Laparoscopic Single-stapling Gastric Transection for Exophytic Pedunculated Gastrointestinal Stromal Tumor

Abstract

Gastrointestinal stromal tumors (GISTs) represent the most common mesenchymal tumors of the gastrointestinal tract. The macroscopic growth of these lesions can be intraluminal, extraluminal, or intramural, but only 6 cases in literature report a description of the pedunculated type. A 69-year-old man was admitted to our department after an echocardiographical control revealing, as an incidental consequence, an epigastric mass. Computed tomography and magnetic resonance imaging showed the presence of an oval lesion between the third segment of the liver and the front wall of the gastric antrum, measuring approximately 40 × 30 mm and suspected for pedunculated GIST. We describe the laparoscopic approach performed and the surgical technique that we suggest in similar cases. Although there are still many controversies on the use of laparoscopy in the treatment of gastric GISTs, laparoscopic resection can safely be adopted for an exophytic pedunculated GIST in an institute with experience in minimally invasive surgery.

Laparoscopic resection for gastric GISTs: surgical and long-term outcomes of 133 cases

“…Complete surgical resection is the primary treatment for local gastric GISTs. Compared with open resection, laparoscopic resection for gastric GIST has advantages such as shorter operative time, less blood loss and quicker recovery [4][5][6]. Therefore, more and more scholars have preferred laparoscopic resection for gastric GIST in recent years.…”
