Abstract: Objective To evaluate the prognosis of infants with common Hirschsprung’s disease who undergo laparoscopic-assisted Soave procedure below 6 months of age,and to explore its feasibility.Methods A retrospective analysis was conducted on the clinical data of 82 cases of common Hirschsprung’s disease admitted to our department from January 2018 to August 2022.The patients were divided into two groups based on their age at the time of surgery:Young surgical age group (<6 months,50 cases) and Old surgical age group (≥6 months,32 cases).All patients underwent the treatment of laparoscopic-assisted Soave procedure.The surgical time,length of hospital stay,postoperative complications,and anal function were compared between the two groups.Results There were no significant differences between young surgical age group and old surgical age group in terms of surgical time [(145.04±11.21) min vs.(149.25±12.18) min,P=0.20],length of hospital stay [(13.56±0.93) d vs.(13.91±0.99) d,P=0.55],postoperative complications [22.00%（11/50）vs.28.13%（9/32）,P=0.53],and Rintala score for anal function [(18.58±1.44) vs.(17.22±1.64),P=0.06].The main postoperative complications,including enterocolitis [10.00%（5/50 ） vs.12.50%（4/32）,P=0.72],fecal/anal incontinence [6.00%（3/50） vs.6.25%（2/32）,P=0.96],and constipation [4.00%（2/50）and 6.25%（2/32）,P=0.65],showed no significant differences between the two groups(all P＞0.05).However,there was a statistically significant difference in terms of bleeding volume [ (7.86±2.02) ml vs.(9.13±2.17) ml,P＜0.05].No deaths occurred in this study.Conclusion Laparoscopic-assisted Soave procedure is safe and effective for infants below 6 months of age with common congenital Hirschsprung’s disease.It can achieve satisfactory anal function and reduce the incidence of adverse events during the waiting period for surgery.
