Safety of double‐balloon enteroscopy in postoperative pediatric patients

Abstract

The aim of the present study was to investigate the efficacy and safety of double-balloon enteroscopy (DBE) in postoperative pediatric patients. This was a retrospective analysis of pediatric patients 18years and younger referred to Mie University Hospital. Twenty procedures in 11 children occurred postoperatively; 29 children (42 procedures) had not undergone surgery. Among postoperative patients, five DBE procedures were performed via the oral route, 12 via the anal route, and three via a stomal route. Among nonoperative patients, 14 DBE procedures were performed via the oral route and 28 via the anal route. Four postoperative patients and two nonoperative patients had difficult pleating via the transanal route because of adhesions or thickening of the intestinal wall resulting from inflammation (P=0.02). Excluding patients with stenosis, the mean length of endoscopic insertion for transanal procedures was significantly shorter among postoperative patients than among nonoperative patients (73.6cm vs 160.5cm, P<0.01). There were no major complications in either group. Insertion difficulty was encountered in postoperative pediatric patients. However, our findings indicate that DBE is a safe procedure in postoperative pediatric patients.
