Cystic duplication of transverse colon: an unusual case of abdominal pain and bowel obstruction

Gatrointestinal duplications are rare congenital anomalies, usually detected prenatally or in the first two years of life, although they can be diagnosed even in older age. Within the abdomen, a small bowel location is the most frequent (more than 50% of cases), while colonic site accounts for 17% of patients; transverse colonic location is very rare. These lesions can vary in shape, being cystic or tubular, and typically show the same structure of the adjacent normal bowel, with which they can have direct communication. The most of case of intestinal duplication in adults present with acute abdomen and bowel obstruction, and are more common in the ileum than in the colon. When diagnosed these lesions should be surgically resected to avoid future possible complications. The Authors present a case of cystic duplication of transverse colon in a young adult male, cause of acute abdominal pain and intestinal obstruction, thus requiring urgent surgery.
