A 67-year-old Caucasian male was admitted to another institution with choledocholithiasis complicated by acute cholangitis. Endoscopic retrograde cholangiopancreatography (ERCP) showed a large duodenal subepithelial lesion fully covering the papilla, and a dilated common bile duct (CBD) with multiple filling defects. Sphincterotomy was performed and CBD stones were removed. The patient underwent laparoscopic cholecystectomy 2 weeks later.
During the subsequent 6 months, he had multiple self-limited episodes of biliary pain. He was admitted twice for this symptom, and on both occasions he underwent ERCP with enlargement of the papillary opening and stone extraction. Abdominal computed tomography ([Fig. 1]), magnetic resonance cholangiopancreatography, and endoscopic ultrasonography documented a duodenal lipoma, but were otherwise unremarkable. The patient was then referred to our tertiary centre. During a multidisciplinary meeting, he was proposed for endoscopic therapy of the duodenal lipoma, as it was assumed that this was the cause of incomplete biliary drainage.

The procedure was performed with the patient in the prone position under deep sedation, with a side-view scope. A yellowish subepithelial lesion of approximately 15 mm was observed in the second duodenal portion, covering the sphincterotomy opening ([Fig. 2]). A biliary plastic stent was temporarily placed to ensure biliary drainage. The lipoma was then looped and ligated with an Endoloop (Olympus, Tokyo, Japan) ([Fig. 3], [Video 1]).

Endoscopic evaluation 3 weeks later showed a periampullary cicatricial area ([Fig. 4]). The patient remained asymptomatic for more than 6 months after the procedure.

Duodenal lipomas are rare tumors [1]. Only three cases of biliary obstruction caused by duodenal lipomas have been reported [1]. The efficacy of the loop-and-let-go technique is well demonstrated in some case series of colonic lipomas [2]. Our case shows the safety and efficacy of this technique in the treatment of a periampullary lipoma – an exceedingly rare lesion. Its usefulness is of paramount importance in the duodenum, as the risk of perforation with snare excision can result in major morbidity.
