Total colonic Hirschsprung disease (TCA) is the most severe form of Hirschsprung disease and is commonly managed with neonatal enterostomy followed by delayed definitive pull-through. Despite widespread use, the optimal reconstructive procedure for TCA remains uncertain. The Duhamel and modified Soave pull-through procedures are the two most frequently adopted techniques, each with distinct theoretical advantages and limitations regarding bowel function, enterocolitis risk, and anorectal physiology. With the increasing application of minimally invasive and robot-assisted surgery, both procedures have been further refined; however, robust comparative evidence, particularly for total colonic disease, is lacking. To date, no multicenter study has provided a detailed comparison of postoperative functional outcomes and Hirschsprung-associated enterocolitis between transanal transection Duhamel and modified Soave procedures. This multicenter study compares robot-assisted transanal transection Duhamel and modified Soave pull-through in patients with pathologically confirmed TCA after neonatal enterostomy, focusing on postoperative bowel function and enterocolitis incidence.
