Comparison of the Duhamel Procedure and Transanal Endorectal Pull-through Procedure in the Treatment of Children with Hirschsprung's Disease: A Systematic Review.

Abstract

Studies comparing the Duhamel and TERPT procedures were included until 22 July 2023. R software (version 4.3.0) was used to perform the meta-analysis. Ten studies with a sum of 496 patients were included. The length of postoperative hospital stay and incidence of postoperative constipation were longer and higher after the Duhamel procedure than the TERPT procedure (p < 0.0001 and p = 0.0041, respectively). The incidence of postoperative anastomotic stricture was higher after the TERPT procedure than the Duhamel procedure (p = 0.0015). No significant differences were found in the incidence of postoperative fecal continence, fecal incontinence/soiling, anastomotic leak, or ileus between these two procedures. The operation time seemed to be similar for both procedures, but it became longer for the Duhamel procedure than the TERPT procedure after sensitivity analysis. While the incidence of postoperative enterocolitis seemed to be higher after the TERPT procedure, it became similar for both procedures in the subgroup analysis. The Duhamel procedure seems to be associated with a longer length of postoperative hospital stay, a higher incidence of postoperative constipation, and a lower incidence of postoperative anastomotic stricture than the TERPT procedure. However, the effect of these two procedures on the operation time and the incidence of postoperative enterocolitis remains unclear.
