Unusual Presentation of Parieto-Visceral Peritoneal Band Obstruction in Adults: The Role of Congenital Peritoneal Bands
Year: 2025
Type: article
Abstract: Peritoneal bands are rare congenital remnants of mesenteric folds that may persist due to incomplete embryological regression. While they are a recognized cause of small bowel obstruction in children, their occurrence in adults is uncommon and often incidental. During routine abdominal dissection of a 42-year-old female cadaver, an atypical parieto-visceral peritoneal band was identified. The band originated from the anterior abdominal wall, approximately two inches above the umbilicus near the apex of the falciform ligament, and coursed posteriorly. It exerted a constrictive effect on the distal stomach at the greater curvature just proximal to the pylorus. The fold bifurcated before termination: one branch blending with the greater omentum and the other attaching to the transverse colon. Fibrous near its origin and fatty distally, the band also contained small vascular twigs. No other anatomical variations or pathological changes were observed. This case illustrates a rare congenital peritoneal band producing gastric constriction without intestinal obstruction. Awareness of such variants is important for surgeons and radiologists to avoid diagnostic confusion or inadvertent intraoperative injury.
