(a) Patient 1: Scheme of the operation site with the malformations of the lower gastrointestinal tract (dilatation of the ascending colon, atresia of the descending colon, blindly closed rest of the sigmoid colon and the rectum, as well as anal atresia) after a double-barreled colostomy at the transverse colon. (b) Patient 1: Operative site of the CSID of the ascending colon. (c) Patient 2: Plain abdominal X-ray showing a sizeable gas-filled bowel loop in right upper abdominal quadrant. (d) Patient 2: Operative site of the mobile dilated duodenum. (e) Patient 3: Scheme of the circumscribed dilatation of the lowest part of the sigmoid colon. (f) Patient 3: Operative site of the dilated segment of the sigmoid colon (diameter of 10 cm), the oral colon with standard configuration. (g) Patient 4: Upper gastrointestinal X-ray series showing pooling of the contrast media in a dilated loop of the ileum in the right hemiabdomen. (h) Patient 4: Intraoperative photograph of an 18-cm-long segmental dilatation of the middle ileum. The arrow in (h) points to the segmental dilatation of the portion of the intestine. The transition of normal bowel on both ends did not show any sign of mechanical obstruction. CSID, congenital segmental intestinal dilatation.
