Gastrointestinal sub-epithelial tumors are frequently diagnosed during endoscopy but they are usually small and do not require any treatment owing to benign behavior [1] [2]. Sometimes these lesions can cause symptoms and their resection is needed [3].

Here we report the case of a 78-year-old man who underwent gastroscopy for intermittent melena and postprandial abdominal discomfort.

Esophagogastroduodenoscopy (EGD) revealed a huge sub-epithelial lesion, covered by ulcerated mucosa, located in the antrum. After needle knife biopsy, histopathology was consistent with lipoma.

Despite medical therapy, the patient referred with melena once again, hence endoscopic submucosal dissection (ESD) was planned.

The lesion was 8 × 6 cm ([Fig. 1]), arising from the submucosal layer. The ESD took 100 minutes and was performed with the pocket creation technique using the DualKnife J (1.5 mm) and ITknife nano (Olympus. Tokyo, Japan) [4].

For a small intercurrent perforation, a traumatic type over-the-scope clip (OTSC) (Ovesco Endoscopy, Tübingen, Germany) was successfully released.

After en bloc resection, the lesion was not pulled out because of its huge dimension in contrast with the smaller diameter of the upper and lower esophageal sphincter. Based on our previous experience, we decided on degradation and digestion in the stomach rather than passage through the pylorus, and thus the resected mass was left in the gastric cavity [5].

The day after, the patient developed obstructive symptoms like blotting and bilioenteric vomiting. A computed tomography (CT) scan revealed a jejunoileal occlusion caused by an intraluminal fat mass, and therefore the patient underwent an urgent laparoscopic enterotomy and the giant resected lipoma was finally extracted ([Video 1]).

Quality:

Lipomas are composed of hard and cohesive fat aggregates. Their digestion may be extremely slow and sometimes incomplete, especially after ESD when high dosages of proton pump inhibitors (PPI) are administered.

In this context, after dissection, extra time for chopping and extraction should be considered to avoid this rare but serious complication.
