[Analysis of the entrance and suture method of umbilical incision in gynecological laparoscopy].

Objective: To explore the entrance and suture method of umbilical incision in gynecological laparoscopy. Methods: A total of 204 cases of gynecologic laparoscopy in our hospital from 2013 to 2016 were reviewed respectively. All the cases used two kinds of approach of umbilical incision: intra-umbilical incision and peri-umbilical incision (longitudinal/transverse oblique/arc incision according to the bellybutton natural skin folds) and two methods of suture: the suture of "U" and the suture of the whole subcutaneous tissue. Two groups were randomly assigned based on the entrance and suture method with each group 102 cases. The peri-operative outcomes were compared, including intra-operative and postoperative bleeding, postoperative incision fat liquefaction and infection, incision pain, incision appearance satisfaction and incision healing satisfaction. Results: The difference was statistically significant in the intra-operative and postoperative bleeding between two groups of intra-umbilical incision and peri-umbilical incision ( P <0.05). There was statistically significant difference in postoperative incision fat liquefaction, infection and incision pain between two groups of the suture of "U" and the suture of the whole subcutaneous tissue ( P <0.05). The incision appearance satisfaction showed no difference ( P >0.05), but the difference was statistically significant ( P <0.05) in the incision healing satisfaction between two groups. Conclusion: The peri-umbilical incision (longitudinal/transverse oblique/arc incision according to the bellybutton natural skin folds) and suture of the whole subcutaneous tissue can be the feasible modified methods with high practicability and security, good cosmetic result. It should be promoted in gynecologic laparoscopy.
