Abstract

BackgroundTransumbilical two-port laparoscopic percutaneous extraperitoneal closure for the treatment of processus vaginalis patency in boys has been practising recent years. The applicable instruments and skills are still evolving. In this study, we used a self-made needle assisted by a disposable dissecting forceps to practise this minimal invasive method for patent processus vaginalis in boys. Its safety and effectiveness were studied. The methods for depth and orientation perceptions were analyzed.MethodsFrom January 2020 to November 2020, boys characteristic of symtomatic patency of processus vaginalis were performed open surgery consecutively. From December 2020, the authors begun to propose transumbilical two-port laparoscopic percutaneous extraperitoneal closure for this kind of boy patients. The open group included fifteen boys and the laparoscopic group included ten ones. The data of the patients age, constituent ratios of unilateral and bilateral patency, operating time, postoperative stay in hospital, follow-up time, conversion, postoperative complications were assessed. Throughout the laparoscopic process, the parallel and synchronous movements of lens pole and dissecting forceps were maintained. Vas deferens protrude was imagined as one of the point to form the triangular manipulation plane.ResultsThere were no statistically significant difference between the laparoscopic group and the open group for the following items: age, operating time, the constituent ratios of unilateral or bilateral patency of processus vaginalis (P > 0.05). Postoperative stay in hospital and follow-up time of the laparoscopic group was significantly shorter than that of the open group (P = 0.0000). No laparoscopic case was converted to open surgery. After 10 cases of laparoscopic practice, orientation perception was established. There were no postoperative complications for all the patients.ConclusionOur preliminary experience suggested that umbilical two-port laparoscopic percutaneous extraperitoneal closure is safe and convenient for patent processus vaginalis treatment in boys. It has the advantage of incision-hiding and can be manipulated like a solo-like surgery.

Summary

Introduction

Transumbilical two-port laparoscopic percutaneous extraperitoneal closure for the treatment of processus vaginalis patency in boys has been practising recent years. The concept of single-port laparoscopic percutaneous extraperitoneal closure of the patent processus vaginalis was adopted for its obvious advantages of incision-hiding and simplicity [12]. Another merit was its space-sparing without more instruments intervention in the limted abdominal cavity of children. How the two-port instruments manipulating simultaneously in the limited umbilical area was the key point for the technique performance This showed that more details of technical improvements were still deserved of being studied for the purpose of shortening the learning curve of this advanced technology. We practiced the technique through umbilical two-port laparascopic percutaneous extraperitoneal closure for patent processus vaginalis in boys. The solo-like surgical manipulation of lens pole and assissting forceps and the orientation perception of this technique were analysed
