A 47-year-old lady with a history of ulcerative colitis on in fl iximab maintenance therapy presented with intermittent severe abdominal pain for a few days. Physical examination revealed no palpable abdominal mass. Computed tomography of abdomen and pelvis revealed a short-segment ileoileal intussusception in the right lower abdomen with no evidence of proximal bowel obstruction. A follow-up computed tomography enterography delineated a 9-mm intraluminal mass with macroscopic fat attenuation at the mid-ileum, possibly a submucosal lipoma, which acted as the lead point for the intussusception (Fig. 1a). As she remained stable with no evidence of intestinal obstruction or ischemia, her intussusception was managed non-operatively. She subsequently underwent single-balloon enteroscopy, which con fi rmed the presence of a 25-mm polypoid lesion at the mid-ileum, which was soft and indentable when pressure was applied using forceps (Fig. 1b). The location of the lesion was marked by endoscopic tattooing, to facil-itate localization in case of need for subsequent surgery. The base of the polyp was then captured using endoloop (Fig. 1c), and hot snare resection was performed. The resection base was further secured by application of endoscopic clips (Fig. 1d).
