Clinical Efficacy of an Indwelling Transanal Tube for the Prevention of Anastomotic Leakage After Hirschsprung's Disease: A Single Center Experience with Chinese Patients.

The aim of this study was to investigate the clinical effectiveness of an indwelling transanal tube for the prevention of anastomotic leakage (AL) after a radical operation for Hirschsprung's disease (HD). We retrospectively analyzed the clinical data from 158 patients who had undergone laparoscopic-assisted Soave procedures for HD at our hospital from May 2015 to May 2019. Patients were divided into two groups depending upon whether the anal drainage tube was retained or not retained: an indwelling group (group A,  = 86) and a no-indwelling group (group B,  = 72). All 158 children had a successful operation by a laparoscopic technique. There was no significant difference in the duration of the operation, the length of the incision, the amount of bleeding, or the postoperative hospitalization time between the two groups. Compared with the no-indwelling group, maintaining the transanal tube had significant advantages for preventing incidences of AL ( < .05). The 4-year follow-up showed that the incidence of postoperative enterocolitis with the indwelling transanal tube was significantly lower than in the group without the drainage tube ( < .05). The laparoscopic-assisted Soave procedure with an indwelling transanal tube is a safe and feasible method for the treatment of HD in children. This method can not only drain intestinal contents but also reduce the occurrence of AL.
