Polyp Endotherapy for Multiple Jejunal Lipomas Presenting as Small Bowel Intussusception: “Loop and Let Go Technique”

Abstract

A 46-year-old woman presented with abdominal pain, vomiting, and intermittent constipation for the last 2 days. She had similar history of recurrent symptoms for the last 6 months. Abdominal examination showed mild central abdominal tenderness and generalized abdominal fullness and no palpable mass. A diagnosis of intestinal obstruction was considered. Nasogastric aspiration was performed with intravenous (IV) antibiotics and IV fluids. Computed tomography (CT) scan of the abdomen showed “bowel in bowel” or “target” sign appearance of jejunum with a submucosal hypodense lesion (suggestive of lipoma) acting as the lead point. There were two more submucosal lipomas of sizes approximately 3 cm each in the distal jejunal loops. A diagnosis of jejunal lipomas causing small bowel intussusception was made. The patient improved with conservative management. Exploratory laparotomy was planned with an intent to resect the small bowel. The patient did not provide consent for the same and so the option of enteroscopy-guided polyp endotherapy was offered to the patient. An antegrade single balloon enteroscopy was done (SIF-Q180, Olympus Medical Systems, United States). Three submucosal lesions with smooth overlying mucosa were noted in the mid and distal jejunum consistent with lipomas. The base of the lesions was ligated tightly using endoloop to make them ischemic and detach. Notable changes in color and mucosal appearance were noted after the application of endoloop. Since all the lipomas detected on cross-sectional radiologic imaging have been tackled via antegrade route, a retrograde enteroscopy was not attempted further. After 2 days, the patient was discharged in stable condition. Follow-up cross-sectional imaging at 3 months showed no residual lipomas, and she remained symptom-free at the end of 6 months.
