Abstract

Introduction

Pyloromyotomy is the standard care for hypertrophic pyloric stenosis. The traditional approach for this procedure is a right upper quadrant transverse incision, although other “open” approaches, such as circumumbilical or periumbilical incision have been described. The more recent approach used is laparoscopic pyloromyotomy (LP), but experience feedback is still debated and its benefits remain unproven. The aim of this study was to make a review of all our LP procedures with an objective evaluation according to the literature.

Methods

A retrospective analysis of all the LPs performed in one University Children’s Hospital between 1 January 1996, and 30 December 2015 was realized. Information regarding the patient’s status, intraoperative and postoperative data was analyzed.

Results

407 patients were included in this study. The mean operative time of the overall procedure was 24 ± 13 min, which significantly increased with the length of the pyloric muscle (p = 0.004) and significantly impacted the full feeding time (p = 0.006). 3.4% required conversion to an open procedure during the LP. We observed a significant correlation between conversion for mucosal perforation and weight loss (p = 0.04) and between conversion for mucosal perforation and preoperative weight (p = 0.002). A redo procedure was indicated in 3.7%, for incomplete pyloromyotomy each time. The mean postoperative hospital length of stay for all procedures was 1.6 ± 0.8 days. There were no inflammatory scars. None had incisional hernias or wound dehiscence.

Discussion

LP procedure appeared to be as quick as the open procedure. Our results were similar to others series for intraoperative complications. According to operative time, this technique does not have an impact on operative room utilization. Vomiting duration at presentation in HPS does not seem to have a significant impact on postoperative outcomes. LP procedure causes little pain during the postoperative period. No wound complications were registered.
