Minimally invasive management of an ascending colonic perforation secondary to distal biliary stent migration: a multidisciplinary, novel laparoendoscopic approach.

Endobiliary stents placed for benign and malignant indications can spontaneously dislocate from the biliary system and migrate to the distal gastrointestinal tract. Stent migration can result in gastrointestinal perforation, with the most common locations in the sigmoid and distal colon, and may require surgical intervention. We describe the case of a 60-year-old female presenting with an ascending colonic perforation secondary to a dislodged plastic biliary stent placed for palliation of her gallbladder carcinoma. The patient was managed with a combined laparoendoscopic approach by a multidisciplinary team-gastroenterology performed an endoscopic stent retrieval and colorectal surgery identified the location of the perforation laparoscopically and performed colonic serosal repairs. The patient had an uneventful postoperative course and was discharged on postoperative day 4. This case demonstrates a novel minimally invasive laparoendoscopic approach at a high-volume academic center for the treatment of ascending colonic perforation secondary to biliary stent migration.
