Abstract:Background: Congenital bands cause 3 % of all intestinal obstruction and almost always lead to small bowel obstruction. In adults, obstruction due to bands is even rarer. Materials and methods: A multicenter study in Turkey. From January 2000 to December 2010 inclusive -a period of 10 years -all adult patients admitted to the emergency departments with a clinical diagnosis of acute intestinal obstruction due to congenital peritoneal band were included in the study. Surgery was defi ned as emergency. Recorded operative fi ndings included the site of obstruction, and the operative procedure to relieve it. In the present study, the fi ndings in adult patients with congenital band reported in the literature together with fi ndings in ten cases operated at four center were retrospectively assessed with respect to their demographic, preoperative, peroperative, and postoperative characteristics. Results: There were 8 males and 2 females aged between 18 and 72 year. There were no history of abdominal or inguinal surgery. Plain abdominal X-rays radiography revealed air-fl uid levels in all patients. All the bands were ligated and divided. On histopathological examination, the bands were composed of loose connective tissue containing blood vessels. There were no calcifi cation in the bands. Conclusion: an anomalous congenital band could be included in the differantial diagnosis of intestinal obstruction. This clinical situation requires early surgical intervention that will be diagnostic and therapeutic (Tab. 1, Fig. 4, Ref. 21). Full Text in PDF www.elis.sk.
