    Abstract:
    INTRODUCTION: Intestinal malrotation is an uncommon developmental anomaly that can lead to duodenal obstruction and midgut volvulus. The standard correctional operation, Ladd's operation, is traditionally performed using an open approach, but providers are increasingly performing the procedure laparoscopically. However, there remains concern that the reduced adhesive burden associated with laparoscopy could predispose to recurrent volvulus. METHODS: We queried our institutional database from 2012 to 2022 for patients <18 years who underwent Ladd's operation for malrotation. We analyzed baseline characteristics and outcomes including post-operative volvulus, adhesive small bowel obstruction (SBO), duodenal obstruction, and overall abdominal re-operation. RESULTS: We identified 226 patients, of whom 90 (40%) underwent a laparoscopic operation. Those undergoing open surgery were younger and had a higher rate of volvulus compared to laparoscopic patients. There were no differences in surgical history or underlying comorbidities. Laparoscopic patients were less likely to develop a post-operative adhesive SBO [1/90 (1%) vs 14/136 (10.0%); OR 9.4 (1.7-176.4), p = 0.036] with no increased rate of volvulus [1/90 (1%) vs 1/136 (0.7%), p = 0.778]. However, there were four laparoscopic patients that required re-operation for a duodenal stricture or kink, which led the overall rate of abdominal re-operation to not be different [7/90 (8%) vs 16/136 (12%); OR 1.6 (0.6-4.8), p = 0.371]. Median follow up was 2.3 years [IQR 1.0-5.0]. CONCLUSION: Laparoscopic correction of midgut malrotation demonstrates no increased risk of post-operative volvulus and may reduce the rate of adhesive SBO. These benefits must be weighed against the potential increased risk of duodenal stricture or obstruction secondary to an incomplete Ladd's procedure. LEVEL OF EVIDENCE: III.
