Intestinal Obstruction Due to a Congenital Band: Two Cases of Congenital Bands in Adults

Small bowel obstruction is the most common surgical disorder of the small intestine. Adhesions are by far the most frequent causes followed by hernias, tumors, intussusception, foreign bodies, gallstones, and inflammatory bowel disease. During embryogenesis, abnormal adhesion of the peritoneal folds induces a congenital band which can cause small bowel obstruction. It is extremely rare and usually observed in childhood. We report two cases of small bowel obstructions in adults due to congenital bands. The first patient is a woman of 47 years-old admitted for chronic abdominal pain, and the second one is a 20 years-old man admitted for the etiological assessment of chronic constipation. Surgical exploration was performed revealing a small bowel obstruction due to congenital band with complete resolution of the symptoms after surgery.
