Incidental Finding of GIST During Obesity Surgery

Abstract

The long-term disease-free survival of 100 % in our study establishes laparoscopic wedge resection during RYGB and LSG as safe and effective in treating incidental gastric GISTs <2 cm.

Treatment of gastric gastrointestinal stromal tumor by laparoscopic sleeve gastrectomy in a morbidly obese patient

“…Twothirds of GISTs occur in the stomach and the most common type is epithelial-cell GIST; these are slowlygrowing, sub-mucosal tumors. While they can ulcerate and manifest with bleeding and abdominal pain in rare cases, they are generally identified incidentally (6). GIST can be diagnosed based on endoscopy and biopsy.…”

Incidental Findings of Benign Mesenchymal Tumours during Laparoscopic Gastric Mini Bypass Surgery: Two Case Reports

“…Since preoperative endoscopy or ultrasound are usually not helpful in detecting such tumors and that it is difficult to access the bypassed stomach later, it is important to do per or post-operative examination of stomach by the surgeons [3]. Laparoscopic wedge resection during gastric bypass or sleeve gastrectomy is considered safe and effective in treating incidental gastric GISTs of less than 2 cm in size [9] with negative margins. The follow-up after resection should be based on standard guidelines in the general population, which is a CT scan, every 3 months to 6 months for 5 years and yearly after that.…”

“…A 36 years-old male patient presented to surgical clinic with morbid obesity having a body mass index (BMI) of 44.6 (height: 168cm, weight: 126) [6]. He was booked for Laparoscopic Mini Gastric Bypass surgery.…”

Surgical treatment of gastric GIST with acute bleeding using laparoscopic sleeve gastrectomy: A report of two cases

“…The incidence of GIST is suspected to be more in obese patients undergoing bariatric surgery (0.6%‐0.8%) in comparison with the general population (0.0006%‐0.0015%). The bariatric surgeon has to inspect the stomach during laparoscopy for such tumors and manage the incidentally encountered during a laparoscopic bariatric operation . This is particularly true during gastric bypass, when undiagnosed disease may remain in the excluded stomach, which will be inaccessible to endoscopic exams but also during the LSG preparation, when a possible lesion could be included in the staple line or not removed at all.…”
