Non-classified type duodenal atresia: case report

Our aim is to present a case with initial diagnosis of non-classified type duodenal atresia operated in our clinic. A patient with prenatally suspected to be duodenal atresia was explored. At laparotomy type 3 duodenal atresia was found between 2(nd) and 3(rd) parts of duodenum. In addition, a web was detected distal to the atresic part. Duodenoduodenostomy together with web excision was performed. He had not any additional pathology. Although duodenal atresia is a very well known pathology by pediatric surgeons, though rarely a non-classified type duodenal atresia can be encountered. Possible presence of a second atresia should be kept in mind, proximal and distal segments of the duodenum and intestinal passage must be explored carefully for the presence of second atresic segment before performing duodenoduodenostomy.
