Coronal section of computed tomography without contrast of the abdomen and pelvis demonstrating significant dilation of the colon proximal to the colonic anastomosis from prior sigmoidectomy consistent with an obstructing anastomotic stricture.

The abdominal X-ray demonstrated a dilated colon, and a follow-up CT scan demonstrated significant dilation of the colon measuring approximately 20 cm in diameter just proximal to the colonic anastomosis concerning for an obstructing anastomotic stricture (Figure 1).
Flexible sigmoidoscopy 20 cm from the anal verge demonstrating a 10 mm-long anastomotic stricture with a luminal diameter of 8 mm.

A flexible sigmoidoscopy revealed a 10 mm-long anastomotic stricture at 20 cm from the anal verge (Figure 2) with a luminal diameter of 8 mm.

The proximal aspect of the deployed LAMS was inspected with retroflexion with an ultrathin upper endoscope to ensure appropriate positioning of the stent (Figure 3).
