The complexity of embryological development of the gastrointestinal tract and mesentery provides a platform for the formation of a wide variety of variant veils, folds, and membranes, collectively termed peritoneal bands. These structures, which represent anatomically unabsorbed portions of the omentum and mesentery, although often benign, have the potential to cause clinically significant manifestations in both the neonate and adult. Although these deviant structures may be identified over a broad range of the abdominal cavity, they are most commonly identified in the regions of the duodenum, duodenojejunal flexure, ileocecal junction, and ascending colon. As a result of the diverse location of these variant structures, clinical manifestations are highly variable, ranging from acute presentations of intestinal necrosis as a result of strangulated midgut volvulus to chronic, vague abdominal pain. This article seeks to highlight the importance of a thorough anatomical understanding of the distribution of the various abnormal peritoneal folds, bands, and ligaments, which may result from aberrations in embryonic gastrointestinal development and their respective clinical implications. Moreover, to advance the knowledge of peritoneal bands, this article discusses the appropriate diagnostic studies and treatment interventions required for these variant structures.
