Low-Residue Diet Versus Rectal Enema Before Laparoscopic Surgery for Endometrial Cancer

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
