Transmesenteric hernia is abdominal visceral herniation through a congenital or acquired mesenteric defect. Treves' field is the area of terminal ileal mesentery circumscribed by the ileocolic artery and its last ileal branch. It is very susceptible to congenital defects. To clarify the clinical course of congenital Treves' field transmesenteric hernia (cTFTH), we retrospectively reviewed pediatric cases and conducted a literature review. Five consecutive pediatric cTFTH cases (one male, four females) underwent emergency laparotomy at our institutions from April 2009 and December 2014. We analyzed their demographics, preoperative findings, surgical procedures, and outcomes, along with a literature review. Abdominal plain X-ray showed displaced intestinal gas with gas paucity in the center of the abdomen in two cases and diffusely increased intestinal gas in two others. Abdominal computed tomography (CT) in four cases showed intestinal loop clusters, mesenteric vessel changes, small-bowel obstruction, and ascites. All cases underwent emergency laparotomy for ileal resection with ileocecal valve preservation. Simultaneous anastomoses were performed in four cases; the remaining case underwent ileostomy because of prematurity. Although one case needed reoperation for postoperative bowel obstruction, all patients survived. Literature review of pediatric cTFTH showed a high frequency of necrosis (70.5%) and mortality (26.5%). Among pediatric cTFTH cases, 67.6% were aged <5 years. Mesenteric defect was <5 cm in 70% cases. We should be aware of the clinical importance and radiological features of pediatric cTFTH. Abdominal CT may provide useful information.
