Abstract
We report the first documented pediatric case of the Deloyers procedure performed using robotic surgery to treat a female patient with long-segment Hirschsprung disease. A 9-month-old child was diagnosed with long-segment Hirschsprung disease. Despite rectal irrigations, the patient experienced refractory constipation and enterocolitis, necessitating exploratory surgery and ileostomy. A transition zone was identified at the proximal transverse colon, with mapping biopsies confirming aganglionosis up to the splenic flexure. At 16 months of age, the child underwent a robot-assisted endorectal pull-through with ileostomy closure. Four 8-mm trocars were placed in the epigastric, left subcostal, right subcostal, and right flank regions. Dissection and mobilization extended distally beyond the peritoneal reflection and proximally to the hepatic flexure, preserving the marginal vascular arcades. The middle and right colic arteries were ligated, while the ileocolic artery was preserved. Indocyanine green fluorescence imaging confirmed adequate vascularization of the hepatic flexure. A counterclockwise 180-degree rotation of the right colon was performed. In the perineal phase, a mucosal incision above the dentate line was followed by progressive mucosectomy to reach the isolated rectum. The colon was pulled through, and a tension-free coloanal anastomosis was performed. The postoperative period was uneventful at the 6-month follow-up. Robot-assisted laparoscopic endorectal pull-through with the Deloyers procedure is a feasible and safe technique for long-segment Hirschsprung disease. Larger case series are required to assess its long-term outcomes and potential advantages. An explanatory video of the surgery is available.
