Objective To investigate the clinical feasibility,safety and advantages of transum-bilical laparoscopic single-site surgery in large hysterectomy.Methods A total of 82 patients with laparoscopic large hysterectomy were selected as the study objects.Among them,41 patients under-went transumbilical single-hole laparoscopic surgery(single-hole group)and 41 patients underwent traditional multi-hole laparoscopic surgery(multi-hole group).Operation time,intraoperative blood loss,24 h postoperative Visual Analogue Score(VAS),postoperative exhaust time,postoperative morbidity,postoperative hospital stay,cosmetic incision score,postoperative inflammatory index,neutrophil lymphocyte ratio(NLR),incidence of complications and the difference of hemoglobin be-fore and after surgery were compared between the two groups.Results The operation was successful-ly completed in both groups without conversion to laparotomy,and no serious surgical complications occurred.No auxiliary holes were added in the single-hole group.The postoperative exhaust time in the single-hole group was significantly shorter than that in the multi-hole group,the VAS score at 24 h after surgery and NLR at the first day after surgery were significantly lower than those in the multi-hole group,and the aesthetic score of the postoperative incision was significantly higher than that in the multi-hole group(P＜0.05).Conclusion Under the condition of strict control of surgi-cal indications,transumbilical laparoscopic single-site surgery in large hysterectomy has good safety and high feasibility,and has the advantages of fast postoperative exhaust,relieved postoperative pain,light immunosuppression and a incision.
