Abstract:
A laparoscopic approach for malrotation is feasible and safe in hemodynamically stable neonates without intestinal necrosis; however, volvulus is associated with recurrence and conversion. We developed a novel approach using a laparoscopic duodenal-caudal detachment method to perform the Ladd procedure for neonates with volvulus under the limited view of laparoscopy. This study presents the results, effectiveness, and details of the method. In the laparoscopic duodenal-caudal detachment method, we first detached the adhesions around the duodenum, including the Ladd's band. After the adhesions were completely removed, the duodenum was freely drawn caudally, leading to the release of torsion. We retrospectively reviewed the medical records of patients who underwent surgery for malrotation of the volvulus at 30 days of age between January 2014 and September 2021. Seven neonates underwent the laparoscopic duodenal-caudal detachment method and 13 underwent the open Ladd procedure. The new technique was performed in all 7 patients, and there were no conversions or recurrences. The operation time was significantly longer in the laparoscopic procedure group (55 minutes versus 111 minutes; P < .01). Our detorsion method, involving an initial incision of the Ladd's band, is safe and effective for neonates and may lead to an improvement in the conversion rates.
