Effect of Oral Laxative Use Before Colorectal Surgery on Intraoperative Surgical Difficulty
Sponsor: Van Training and Research Hospital
Summary
This prospective randomized pilot study will evaluate whether the use of an oral laxative before elective laparoscopic colorectal surgery affects small-bowel diameter and intraoperative surgical difficulty. Adult patients scheduled for elective laparoscopic colorectal resection will be randomly assigned to receive either oral laxative plus rectal enema preparation or rectal enema preparation alone. During surgery, the diameters of the jejunum and ileum will be measured using a standardized method. The study will also compare operative difficulty, bowel manipulation time, operation duration, need for additional ports, conversion to open surgery, intraoperative complications, blood loss, and early postoperative outcomes between the two groups. The findings may help clarify whether oral laxative use influences intraoperative conditions during laparoscopic colorectal surgery.

Interventions
Oral Laxative
Participants assigned to the experimental arm will receive an oral laxative as part of preoperative mechanical bowel preparation, in addition to a rectal enema, before elective laparoscopic colorectal surgery. The oral laxative will be administered according to the institution's standard preoperative bowel preparation protocol.
Rectal Enema
Participants in both study arms will receive a rectal enema as part of preoperative bowel preparation before elective laparoscopic colorectal surgery. Participants in the comparator arm will receive the rectal enema without an oral laxative.
