The Incidence of Symptomatic Malrotation Post Gastroschisis Repair

Abstract

Gastroschisis is known to be associated with abnormal bowel rotation. Currently, the broadly accepted practice is not to perform Ladd’s procedure routinely at the time of closure of gastroschisis defects. However the incidence of symptomatic malrotation and volvulus post gastroschisis repair is unknown; this incidence is important in view of the current practice of bedside gastroschisis closure. This study examined the incidence of symptomatic malrotation and volvulus following gastroschisis repair.

Method:

Patients who had undergone gastroschisis repair between 1999 and 2009 in any of 2 tertiary centers were identified using the Hospital Inpatient Enquiry system. The medical records were reviewed to obtain demographic data and postoperative outcomes. Patients were contacted for follow-up.

Results:

128 patients were identified with a median postoperative follow-up of 4 years (range: 6 weeks to 12 years). Upper gastrointestinal (GI) contrast studies were performed in 30 patients (23.4%), 21 (16.4%) of whom showed evidence of malrotation. Malrotation was documented during the primary repair in 12 patients (9.4%); however Ladd’s procedure was performed primarily in only 3 patients. 7 patients underwent Ladd’s procedure in a second laparotomy for mechanical obstruction secondary to causes not related to malrotation and volvulus. A total of 29 patients (22.7%) had either operative or radiological evidence of malrotation. None of these patients developed volvulus after being followed for a median period of 4 years.

Conclusion:

Bedside gastroschisis closure without concomitant Ladd’s procedure is a safe practice. None of the patients with documented malrotation developed volvulus post gastroschisis repair.
