Objective To investigate and analyze the clinical features of children with colorectal polyps and the efficacy of laparoscopic surgery combined with colonoscopy. Methods A total of 98 children with colorectal polyps diagnosed and treated in our hospital from February 2019 to October 2021 were selected as subjects of this study. The clinical characteristics of all children were recorded,and they were divided into the laparoscopic group(laparoscopic surgery combined with colonoscopy,n=40)and the colonoscopy group(colonoscopy,n=58)according to the differences in surgical methods. The therapeutic effect,complication rate,VAS pain score,polyp recurrence and reoperation rate of different surgical methods were compared. Results Among the 98 children,the polyps of 44 cases were in rectum,38 cases in transverse rectum and 16 cases in other sites. The maximum diameter of polyp was(1. 65±0. 24)cm. Polyps were solitary in 83 cases and multiple in 15 cases. The perioperative indexes in the laparoscopic group were significantly improved compared with those in the colonoscopy group(P<0. 05). The incidence of postoperative complications such as infection,bleeding,intestinal perforation and intestinal obstruction was 5. 00% in the laparoscopy group,which was significantly lower than 17. 24% in the colonoscopy group(P<0. 05). The total effective rate of laparoscopic group was 97. 50% one month after operation,which was significantly higher than that of colonoscopy group(82. 76%,P<0. 05). The VAS pain score of the laparoscopic surgery group was significantly lower than that of the colonoscopy group at 1,3 and 7 days after surgery(P<0. 05). After 1 year of follow-up,the combined polyp recurrence rate and reoperation rate were 5. 00% and 2. 50%,which were significantly reduced compared with 18. 97% and 13. 79% in colonoscopy group(P<0. 05). Conclusions The main sites of colorectal polyps in children are rectum and transverse rectum,and most of them are solitary. Laparoscopic and colonoscopic surgery for colorectal polyps in children can promote the recovery of children,improve the overall treatment effect of patients,relieve the pain of children,reduce the occurrence of complications,and reduce the recurrence rate and reoperation rate of follow-up polyps in children.
