A Case of Bowel Obstruction Due to an Anomalous Congenital Band With Asymptomatic Meckel’s Diverticulum

Abstract

A 14-year-old boy complained of abdominal pain, and he was admitted to our hospital with a diagnosis of bowel obstruction. A computed tomography of the abdomen revealed stenosis of the ileum. Three days after admission, laparotomy revealed an anomalous congenital band, which extended from the ileum to the mesentery, and asymptomatic Meckel’s diverticulum, which was located close to the oral side of the band. We performed simple resection of the band and Meckel’s diverticulum. His abdominal pain recurred 10 days after the first operation, and computed tomography revealed restenosis of the ileum. We performed laparotomy12 days after the first operation. The stenosis was caused by the adhesion between the band and the resection site of Meckel’s diverticulum. Therefore, we performed partial resection of the ileum. His postoperative course, after the second surgery, was uneventful with no recurrence of bowel obstruction. Bowel obstruction caused by an anomalous congenital band excluding omphalomesenteric duct remnants and vitelline vascular remnants is rare. Furthermore, an anomalous congenital band with asymptomatic Meckel’s diverticulum is extremely rare. Although simple resection is usually opted for asymptomatic Meckel’s diverticulum, our observations indicated that partial resection of the ileum should be one of the surgical choices to treat bowel obstruction caused by an anomalous congenital band with asymptomatic Meckel’s diverticulum.
