Improve Of Gasless Laparoscopic Single-Site Suspension And Use In Surgery For Endometrial Cancer

Objective: To investigate the improve in Gasless Laparoscopic single-site suspension and use in surgery for endometrial cancer.And to compare the outcome of different surgical style in endometrial cancer. Method: A tissue retractor is added to the routine step of Gasless Laparoscopic single-site(GLESS) to lift the abdominal wall upward. Lateral umbilical ligament was exposed, and 2-0 buckwheat thread was passed through the umbilical ligament and abdominal wall, then lift the umbilical ligament.Measure the changes of space length or height in different dimensions of improved GLESS. Measure the vertical height from the upper edge of the umbilical hole to the abdominal cavity, the length from the lower edge of the umbilical hole to the right Michaelis point, the height from the bottom of the uterus to the peritoneal cavity of the anterior abdominal wall, and the length from the lateral umbilical ligament to the ipsilateral psoas major muscle.To analyze the differences operations of 177 cases of endometrial carcinoma in operation time, hemoglobin change, number of lymph nodes removed, postoperative exhaust time and postoperative complications of open surgery, multi site laparoscopic surgery, single site laparoscopic surgery and gasless Laparoscopic single-site surgery for endometrial cancer. Result: After improvement, the operation space increased significantly. There was no significant difference in the operation time, hemoglobin change, number of lymph nodes removed, postoperative exhaust time and postoperative complications of endometrial cancer. Conclusion: The improvement of GLESS can exposed to a greater surgen space. At the same time, the way of suspending the umbilical ligament through abdominal silk thread can expose the anatomical structure of obturator position to a greater extent.The application of GLESS in the operation of endometrial cancer is safe and feasible.
