Objective  To investigate the application value of transumbilical single-port laparoscopy in the operation of benign adnexal tumors in middle-aged and elderly women.

  Methods  Totally 37 patients with benign adnexal tumors were randomly divided into experimental group (transumbilical laparoscopy) with 17 cases and control group (porous laparoscopy) with 20 cases. The clinical outcomes during and after operation were compared between the two groups.

  Results  The operations were successful in both groups, and none of them was converted to open surgery. There were no significant differences in operation time, intra-operative bleeding volume, postoperative exhaust time and hospitalization time between the two groups (P>0.05). Compared with the control group, the pain score of the experimental group was lighter and the satisfaction degree was higher, and there were significant differences (P < 0.05). Postoperative pathologic result was benign tumors in both groups, which was consistent with preoperative diagnosis. All patients were followed up for 1 to 3 months. The wound healing was satisfactory. No complications such as infection, delayed healing, venous thrombosis, intraperitoneal hemorrhage, subcutaneous hematoma and incisional hernia occurred were observed.

  Conclusion  Transumbilical single-port laparoscopy is safe and effective in the treatment of benign adnexal tumors in middle-aged and elderly women, with advantages of light pain and small incision.
