Natural Orifice-Assisted Laparoscopic Meckel Diverticulectomy Incidentally Found During Para-Aortic Mass Resection

Laparoscopic resection of the retroperitoneal schwannoma and Meckel diverticulum were successfully performed in this patient with history of stage IV choriocarcinoma. To our knowledge, this is the first report describing a natural orifice-assisted laparoscopic approach for resection of Meckel diverticulum. Natural orifice-assisted laparoscopy should be considered when the surgeon needs to remove a large specimen and/or to introduce >5-mm diameter instruments into the peritoneal cavity without having to extend the abdominal incisions.
