Endometrial Cancer Clinical Trials

The goal of this clinical trial is to compare a standardized 3-day bowel preparation protocol with a rectal enema before laparoscopic surgery for endometrial cancer. The study will evaluate whether the dietary bowel preparation protocol can be used instead of a rectal enema while maintaining an adequate surgical view during surgery. The main questions it aims to answer are: * Can the dietary bowel preparation protocol provide surgical exposure comparable to a rectal enema? * Can the dietary bowel preparation protocol reduce the minimum Trendelenburg position and pneumoperitoneum pressure required to obtain an adequate surgical view? * Does either bowel preparation method cause more discomfort or side effects before surgery? Researchers will compare a standardized 3-day bowel preparation protocol with a rectal enema before surgery. Participants will: * Be randomly assigned to receive either a standardized 3-day bowel preparation protocol or a rectal enema before surgery. * Undergo standard laparoscopic surgery for endometrial cancer. * Have surgical exposure, the minimum Trendelenburg position, the minimum pneumoperitoneum pressure, operative outcomes, postoperative recovery, and bowel preparation-related symptoms and discomfort assessed as part of routine clinical care.
