Brief summary

This randomized controlled trial compares Lee-Huang point entry with conventional umbilical entry for laparoscopic surgery in patients with endometrial cancer. The study aims to evaluate the success of abdominal entry, entry-related complications, operative outcomes, and perioperative safety. A total of 202 patients were randomized to either the Lee-Huang entry group or the umbilical entry group and underwent laparoscopic surgical staging. The findings are expected to provide evidence regarding the optimal primary entry technique for laparoscopic management of endometrial cancer.

Detailed description

This single-center prospective randomized controlled trial was conducted at the Department of Gynecologic Oncology, Kartal Dr. Lutfi Kirdar City Hospital, University of Health Sciences Turkey. Eligible patients with endometrial cancer scheduled for laparoscopic surgical staging were randomly assigned to either Lee-Huang point entry or conventional umbilical entry. The primary objective was to compare successful abdominal access and entry-related complications between the two techniques. Secondary outcomes included operative time, blood loss, conversion to laparotomy, intraoperative and postoperative complications, and other perioperative outcomes. A total of 202 patients completed the study.

Interventions

PROCEDURELaparoscopic entry through the Lee-Huang point

Initial laparoscopic abdominal entry was performed by direct tracar insertion through the Lee-Huang point

PROCEDUREStandart umbilical laparoscopic entry

Initial laparoscopic abdominal entry was performed by direct trocar insertion through the umbilicus.
