Outcomes After Laparoscopic Gastrostomy Suture Techniques in Children

Abstract

Background: There are various suture techniques used during laparoscopic gastrostomy to secure the stomach to the anterior abdominal wall. However, it remains unclear whether temporary fixation or subcutaneous absorbable sutures predispose pediatric patients to fewer postoperative complications. Our goal was to determine if a particular suture technique resulted in an increased risk for the development of postoperative complications.

Materials and methods: A retrospective cohort analysis was performed for patients less than 18 y of age who underwent laparoscopic gastrostomy at a tertiary Children's Hospital between 2012 and 2016. Children were grouped according to suture techniques for laparoscopic gastrostomy placement: temporary sutures or subcutaneous absorbable sutures. Postoperative outcomes at 30 d were defined as major complications (tube dislodgement, unplanned reoperation, readmission) and minor complications (stitch abscess, surgical site infection, emergency department visit). The chi squared test was used to determine if an association existed between the suture techniques and 30 d postoperative complications.

Results: We identified 682 pediatric patients who underwent laparoscopic gastrostomy. There were 301 (44%) patients with subcutaneous sutures placed and 381 (56%) with temporary sutures placed. The overall rate of major and minor complications was 8.3% and 22%, respectively. We observed a significant difference in the occurrence of major postoperative complications between the subcutaneous and temporary suture techniques (11% versus 6.3%, P = 0.029). There was no significant difference in the development of minor complications between subcutaneous and temporary suture techniques.

Conclusions: Children who receive subcutaneous sutures during laparoscopic gastrostomy are at an increased risk for developing a major postoperative complication.
