Intramesosigmoid Hernia with Obvious Symptoms Triggered by Oral Administration of Laxative

Abstract

A 51-year-old woman with no previous history of laparotomy was admitted to a local hospital with chief complaints of constipation and abdominal discomfort for over 1 month. Abnormalities in upper and lower gastrointestinal endoscopic examinations had not been pointed out in the past. She experienced sudden nausea and abdominal pain after oral administration of laxative, and was referred to us because of ileus. Decompression using a long intestinal tube did not achieve symptomatic remission; therefore, an emergency diagnostic laparoscopy was performed, leading to a diagnosis of intramesosigmoid hernia. The incarcerated ileum was resected, and the hernia orifice was then closed by suturing laparoscopically. Intramesosigmoid hernia is a relatively rare disease and may be difficult to diagnose, and many cases cause an acute outcome. We report here a case of intramesosigmoid hernia that caused a subacute outcome triggered by oral administration of laxative.
