Abstract
A 7-year-old boy sometimes had abdominal pain and nausea for the past 2 years. Abdominal ultrasound and video fluoroscopy showed that he had intestinal malrotation. Laparoscopy revealed that the cecum was not fixed to the retroperitoneum and a Ladd’s ligament was found. Moreover, the ligament of Treitz was located medially and abnormally. We diagnosed him as having atypical intestinal malrotation and performed laparoscopic Ladd’s procedure. His appetite was good and he was discharged on postoperative day 7. He had abdominal pain and nausea again on postoperative day 10.Video fluoroscopy showed duodenal stenosis suspected to be related to postoperative adhesions. We performed endoscopic balloon dilatation and the postoperative duodenal stenosis was improved. After that, he no longer had the symptoms.
