Successful management of a full-thickness muscularis propria defect with an omental patch after endoscopic resection of an 50 mm gastric GIST

Abstract Text A 69 year old female received an upper GI endoscopy; a 50 mm, submucosal, ulcerated, bulky, lesion was found in the gastric body. CT scan confirmed a gastric GIST without loco-regional lymph nodes or metastasis. Submucosal Tunnelling Endoscopic Resection (STER) was attempted but due to the ulceration completion was not feasible. During tunnelling, tumour involvement of the muscularis propria was revealed. The dissection was completed from the muscularis resulting in a large full-thickness defect of the gastric wall. Due to the size of the defect closure was difficult and successfully achieved with an omental patch fixed with through the scope endoscopic clips. Histopathology confirmed the GIST (pT2NX, mitotic index of 4 per 5 mm²). MDT discussion agreed to follow-up. No additional treatment was deemed necessary. 6 months radiologic, endoscopic and histologic follow-up was negative.
