The patient had a history of right hemicolectomy for adenomatous polyp. CT features are suggestive of acute bowel obstruction at the site of ilio-transverse anastomosis with the formation of proximal fecaloma.
Fecaloma at the anastomotic site is rare and can be treated with colonoscopic mechanical fragmentation in patients without an absolute indication for surgery 1. Risk factors for post-colectomy fecaloma include female gender, left-side colonic anastomosis, and functional end-to-end anastomosis 1.
