A 38-year-old woman with a history of total gastrectomy in 2006 for adenocarcinoma presented with complaints of severe right-sided abdominal pain and dysphagia. The patient had experienced progressive intolerance to solid foods and a 50-lb weight loss over 1 year. Work-up at an outside institution revealed recurrent cancer at the esophago-enteric anastomosis, and a 23 mm × 100 mm Wallflex partially covered esophageal stent (Boston Scientific, Natick, Massachusetts, USA) was placed at that time. The patient noted rapid recurrence in dysphagia and concomitant abdominal discomfort after 2 days.
An abdominal radiograph showed the stent in the right lower quadrant with no dilated loops of bowel or free intraperitoneal air ([Fig. 1]).

An abdominal computed tomography scan showed the stent in the ascending colon ([Fig. 2]).

After 72 hours of conservative management, which failed, the decision was made to pursue endoscopic retrieval.
Using an Olympus CF-H180 colonoscope (Olympus Corp., Tokyo, Japan), we attempted to place a snare around the stent in the ascending colon ([Fig. 3]) but could not encase it circumferentially as the distal end flared to 28 mm.

A rat tooth forceps was then utilized to draw the stent into the left colon. The stent could not be withdrawn further due to sharp turns in the descending colon. A double-channel upper endoscope (Olympus GIF-2TQ160) was advanced, and a rat tooth and biopsy forceps were used simultaneously to grab opposite ends of the stent ([Fig. 4]).

After a total of 70 minutes of maneuvering, the stent was withdrawn from the rectum ([Fig. 5]), and the patient recovered without issue.

Placement of self-expandable stents is an accepted option for malignant esophageal obstruction after gastric surgery [1]. Migration is an uncommon, but known, complication of esophageal stent placement [2]. This case illustrates an extremely rare occurrence of a 100-mm long stent migrating through the small intestine into the colon, and highlights a successful endoscopic retrieval technique using a combination of endoscopic tools.
