Through the comparative study of transumbilical laparoscopic single site surgery and traditional laparoscopy surgery, to explore the application value of transumbilical laparoscopic single site surgery in the treatment of gynecological benign diseases.

From Nov. 2016 to Jan. 2018, 80 patients with benign gynecological diseases were treated in the 731 Hospital of China Aerospace Science and Industry Corporation and the Second Hospital of Hebei Medical University. According to the surgical method, the patients were divided into two groups: transumbilical laparoscopic single site surgery group (n=40) and traditional laparoscopic surgery group (n=40). The operation time, intraoperative blood loss, conversion rate, postoperative exhaust time, pain, length of stay in hospital and complications were compared between the two groups.

In both groups, the operation was successful and there was no conversion to laparotomy, and no complications occurred 1 year after follow-up. There was no significant difference in intraoperative blood loss, postoperative exhaust time and length of stay in hospital between the two groups. The operation time in the single site group was longer than that in the traditional group [(111.00 ±54.90)min vs (79.67±42.45) min]. The VAS pain score in the single site group was significantly lower than that in the traditional group at 3 days after operation [(2.6±0.92) vs (2.0±0.98)]. The difference was statistically significant (P<0.05). The visual analogue scale pain score in the single site group was significantly lower than that in the traditional group (P<0.05). The difference was statistically significant (P<0.05).

Transumbilical laparoscopic single site surgery is minimally invasive, safe and feasible. Compared with traditional laparoscopic surgery, the postoperative pain is obviously alleviated.
