Abstract
BACKGROUND:Hirschsprung-associated enterocolitis (HAEC) is a significant complication of HD both in the pre- and postoperative periods. This was a large multicenter series study to determine the effect of preserving a postoperative rectal tube on preventing HAEC after primary laparoscopic endorectal pull-through procedure. METHODS:Between 2014 and 2017, a total of 383 consecutive patients with rectosigmoid segment HD were randomly divided into group A (n = 190) and group B (n = 193). All of them underwent primary laparoscopic pull-through procedure, with the same postoperative treatment protocols except for group A with a rectal tube after surgery for 5 days, while group B did not have it. The mean time of follow-up was 2.0 ± 0.53 years (0.5-3.6 years). Demographics, operative data, postoperative complications, and clinical outcomes were compared between these two groups. RESULTS: Outcomes within 1 month after surgery indicated a lower incidence of abdominal distention (4% vs 15.5%, P < 0.05) and postoperative HAEC (1.2% vs 6.8%, P < 0.05) in group A compared to group B. Beyond 1 month after surgery, the overall incidence of HAEC was not significantly different (12% vs 13.1%, P = 0.54). However, further analysis revealed that the patients who suffered HAEC twice or above twice in group A were significantly less than those in group B (3.6% vs 8.3%, p = 0.02). There were no significant differences in the defecation frequency and other complications. CONCLUSIONS:Primary laparoscopic endorectal pull-through procedure with a postoperative rectal tube can reduce the early-stage postoperative incidence of abdominal distension and HAEC and the risk of HAEC recurrence in the long term, and is beneficial to postoperative management. LEVEL OF EVIDENCE: Level 2.
