Computed tomography (CT) angiogram noted occlusion of the right long superficial femoral artery and an incidental finding of sigmoid diverticulosis and an irregular area of wall thickening in the sigmoid colon (Fig. 1). Repeat colonoscopy identified an impacted foreign body at 30 cm suspicious for impacted dentures (Fig. 1). Repeat CT abdomen pelvis demonstrated a partially opaque foreign body in the thickened sigmoid colon consistent with impacted dentures (Fig. 1). The thickened sigmoid colon was resected (Fig. 1) and a hand sewn full thickness seromuscular single layer end to end colo-colic anastomosis was performed with 3-0 PDS suture.
