A new study published in Journal of Laparoendoscopic & Advanced Surgical Techniques was based on the hypothesis that indwelling low-profile balloon button tube inserted through the appendix into the cecum for antegrade enemas during Malone appendicostomy is effective at managing constipation or fecal incontinence and is associated with a low rate of stenosis. Here, 36 children who underwent laparoscopic appendicostomy balloon button placement at an institution, from January 2011 to April 2017, were identified. In these children, postoperative complications were analyzed. Overall, 35 were included. It was found that 31 patients underwent the operation for idiopathic constipation, 3 patients for anorectal malformation, and 1 patient for hypermobility. The rate of open conversion was 3%. A full response was obtained in 68.6%, partial response in 25.7%, while 5.7% of the patients did not respond. Meanwhile, one patient developed an internal hernia requiring laparotomy, which was followed by mucosal prolapse. Another patient developed a stricture noted at button change. Whereas, 20% of the patients underwent reversal of their appendicostomy tube – five due to return of normal bowel function and two due to discomfort with flushes. From the results, it was concluded that laparoscopic appendicostomy with a balloon button tube is an effective measure for addressing chronic constipation or fecal incontinence. The stenosis rate associated with tube appendicostomy may be lower than those reported for Malone antegrade continence enema procedures.
