Intramesosigmoid hernia: a rare type of congenital internal hernia

Abstract

Intestinal obstruction from congenital internal hernias is a rare and often unsuspected problem. We report the case of a 66-year-old male with a rare type of congenital internal hernia causing bowel obstruction. He underwent successful laparoscopy-assisted surgical repair without bowel resection. Symptomatic congenital internal hernias usually present with intermittent or acute small-bowel obstruction without any history of previous abdominal surgery. Laparoscopy or hand-assisted laparoscopy can be useful tools for locating the region of pathology and enable minimally invasive surgical treatment.
