Background: Midgut malrotation most commonly presents in young children. This diagnosis is not often entertained in the adolescent or adult with abdominal complaints. We reviewed our experience with this subset of malrotation patients. Methods: A retrospective review of medical records from adolescent or adult patients identified with a diagnosis of anomaly of intestinal fixation or malrotation, who were treated within our health system between 1993 and 2004. Results: A total of 33 patients were diagnosed with malrotation and treated with Ladd's procedure. Acute abdominal pain was present in 50%, and chronic complaints were present in the other patients. Initial work-up included computed tomography (CT) scan (28%), upper gastrointestinal (UGI) study (38%), and plain films (47%) Postoperative complications occurred more frequently in patients that were operated on emergently (60%) than in those that underwent elective surgery (22%; p = 0.04). Conclusions: This large case series of intestinal malrotation in the nonpediatric age group suggests that Ladd's procedure can be performed very safely. Moreover, the results suggest that patients with known malrotation should have Ladd's procedure performed electively rather than urgently.
