A novel technique for correction of intestinal atresia at the ligament of Treitz

After reconstruction of jejunal atresias at the ligament of Treitz, many patients do not respond to simple tapering and anastomosis requiring repetitive operations because of dysfunction of dilated proximal bowel. A new operative approach using lateral duodenectomy and duodenojejunostomy (LDAD) is reported.

Three infants with atresias within 10 cm of the ligament of Treitz were treated with LDAD, and their records are reviewed retrospectively. The entire duodenum is visualized after creating a malrotation; this is followed by opening the dilated duodenum and resecting dilated proximal jejunum. The resection is extended proximally, incorporating the lateral duodenal incision, excising the lateral duodenal wall, and preserving the ampulla. The residual duodenum is fashioned into a tube and anastomosed to the spatulated distal jejunum.

Three infants underwent this procedure over a 4-year period. Two had undergone tapering enteroplasties previously but were unable to tolerate oral feedings; 1 infant had LDAD primarily. All were ultimately successfully managed by LDAD and were feeding within 14 days. Follow-up is from 14 to 49 months.

Although experience is limited to 3 patients, the prompt return of intestinal function with LDAD may justify primary use of this more radical procedure in difficult-to-treat proximal atresias.
