RESUMEN
Objective To observe the short-term clinical efficacy of modified transanal Soave surgery on infants with hirschsprung′s disease (HD) in initial radial resection, and to analyze the influencing factors. Methods 132 HD infants were selected. After initial radial resection with modified transanal , Soave surgery was conducted under general or sacral anesthesia. Postoperative antibiotics were routinely given. Results 19-56 cm intestinal canal samples were excised, with average length of (35.07 ± 3.15) cm. The average surgical duration and intra-operative hemorrhagic volume were (120.48 ± 18.34) min and verage was (45.74 ± 8.14) mL. All infants′ gastrointestinal function was recovered in 24 h postoperatively. The total excellent and effective rate of anal function in 6 months was 90.90% postoperatively. Cox modal multivariate analysis suggested that anastomotic orifice stenosis and enteritis were the two factors that greatly influenced the excellent and effective rate of anal function 6 months after the surgery (P < 0.05). Conclusion The modified transanal Soave surgery has small trauma and low complication rate on HD infants in initial radial resection , and the postoperative enteritis and anastomotic orifice stenosis are independent influencing factors for the short-term efficacy.
