[Long term evaluation of transanal surgery with automatic suture in Hirschsprung's disease].

Objective: Retrospective and descriptive study of patients with diagnosis of Hirschsprung disease (HD) in whom transanal pull-through was performed in our center.
Material and Methods: All patients with diagnosis of HD in whom transanal surgery was performed between 2006 and 2018 in our center were selected. In all cases laparoscopic biopsy was performed in the previous dilated area. Once intraoperatory biopsy revealed the presence of ganglionic cells, transanal De la Torre surgery was performed, until reaching the localization of the biopsied area. Circular automatic suture was performed in all cases.
Results: Surgery was performed in 21 patients (16 boys and 5 girls) with a median age of 12 months (5-62). No patient had enterocolitis. The median resection length was 14.5 cm (3-45) and no intraoperative complications happened. One patient (5%) developed a rectosigmoideal abscess, which was solved with antibiotic. One case (5%) needed another surgery due to umbilical trochar eventration. No patient had enterocolitis after the surgery. One patient (5%) had stenosis, solved by its section and other case (5%) had sleeve compression which was solved by laparoscopic section. After a median follow up of 97 months (12-159), one child (5%) developed encopresis, which is treated with periodic anal irrigations and other patient (5%) has chronic constipation, which require periodic enemas. The rest of the patients have no symptomatology.
Conclusion: In conclusion, in our series of cases, transanal pull-through with circular automatic suture was a safe and useful technique. It has a low rate of operative and postoperative complications and provides good prospective results.
