Comparison of clinical outcomes after total transanal and laparoscopic assisted endorectal pull-through in patients with rectosigmoid Hirschsprung disease.

[BACKGROUND] Total transanal (TERPT) and laparoscopic endorectal pull-through (LERPT) are the most common procedures to treat rectosigmoid Hirschsprung's disease (HD). Since few studies have compared the two methods, we aimed to assess clinical outcomes after TERPT and LERPT in this cross-sectional study.

[METHODS AND PATIENTS] All patients with rectosigmoid HD operated with TERPT and LERPT between 2001 and 2018 were eligible. Peri-operative data were registered from patients' records, and bowel function was assessed according to the Krickenbeck classification.

[RESULTS] 91/97 (94%) patients were included; 46 operated with TERPT and 45 with LERPT. Bowel function was assessed in 80 patients at median seven (4-17) years. There was no difference in functional outcome between the procedures. Unplanned procedures under general anesthesia were frequent; 28% after TERPT and 49% after LERPT (p = 0.04). 11% of TERPT and 29% of LERPT patients got botulinum toxin injections (p = 0.03). In the TERPT group, patients operated in the neonatal period had poorer outcome (78%) than those operated later (24%) (p = 0.005). No difference in operative time, length of hospital stay, and rate of early and late complications was found between the procedures.

[CONCLUSION] There was no difference in long-term bowel function in patients with rectosigmoid HD operated with TERPT or LERPT. More LERPT patients had an unplanned procedure under general anesthesia, mostly due to obstructive symptoms.
