Objective To investigate the application value of transumbilical single-port total laparoscopic hysterectomy by conventional instrument without uterine-lifting in the treatment of cervical lesions.Methods We selected 60 cases of total laparoscopic hysterectomy due to cervical high-grade squamous intraepithelial lesion(HSIL)or cervical cancer stage ⅠA1 from December 2021 to June 2023.According to the patients'preference,30 cases of single-port laparoscopy through the umbilicus and 30 cases of multi-port laparoscopy were performed,both using conventional instruments without uterine-lifting.The surgical indicators of the two groups were compared.Results No conversion to open surgery occurred in both groups,and no intraoperative injuries to the urinary system,bowel,or major blood vessels occurred.As compared with the multi-port group,the single-port group had significantly reduced amount of bleeding during surgery[(54.6±20.5)ml vs.(67.5±27.0)ml,P = 0.041],earlier anal exhaust time[(27.6±8.0)h vs.(32.2±9.0)h,P =0.040],and shorter total hospitalization time[(4.4±1.5)d vs.(5.1±1.2)d,P = 0.044].There were no significant differences in uterine weight,surgical time,and postoperative complications between the two group(P>0.05).The healing of the abdominal wall puncture wounds in both groups of patients were satisfied.There were no short-term complications related to the puncture device(such as puncture wound infection and bleeding)or long-term complications(such as umbilical hernia and incisional hernia).Conclusion Transumbilical single-port total laparoscopic hysterectomy without uterine-lifting presents advantages of less intraoperative bleeding,faster postoperative recovery,and almost no scarring,with complications similar to traditional laparoscopic surgery.
