Laparoscopic 'steering wheel' derotation technique for midgut volvulus in children with intestinal malrotation.

Introduction: Since the first description by William Ladd, the Ladd's procedure has been the surgery of choice for the correction of malrotation. The laparoscopic Ladd's procedure is becoming popular with the advent of minimal access surgery and is described in the literature. Various techniques of the Ladd's procedure have been described but none of them describes the stepwise technique for derotation of volvulus which is the most difficult and confusing part of the surgery. We describe 'steering wheel' technique for easy derotation of volvulus associated with malrotation.

Method: A total of 62 patients were diagnosed to have an intestinal malrotation between 2010 and 2017. All cases which had complete non-rotation with a midgut volvulus were reviewed. Out of these, 48 patients were operated with open technique and 14 patients were subjected to the laparoscopic correction.

Technique: Using three-port technique, stepwise derotation of volvulus is done which simulates the rotation of steering of car at an acute turn and has been described in four simple steps. This technique also stresses the importance of the release of Ladd's band before derotation.

Results: Of 62 patients diagnosed with malrotation, 14 (22.6%) patients underwent the laparoscopic Ladd's procedure. The mean age was 26 + 8 months, mean weight was 10 + 2 kg and included eight males (57%) and six females (43%). There was only one (7.14%) conversion to open technique, due to a huge dilatation of duodenum causing difficulty in dissection in a patient with malrotation without volvulus. The laparoscopic Ladd's procedure took an average time of 70 ± 15 min.

Conclusion: The laparoscopic 'steering wheel' derotation technique is easy and provides a stepwise description of the laparoscopic derotation of volvulus associated with malrotation in children.
