Oral laxative before laparoscopic colorectal surgery to see if it changes how hard the operation is

Official title: Effect of Oral Laxative Use Before Colorectal Surgery on Intraoperative Surgical Difficulty

Run by Van Training and Research Hospital · NCT07820696 · Data updated 2026-11-12

This pilot trial tests whether giving an oral laxative before elective laparoscopic colorectal surgery makes the small bowel more distended and affects how difficult the operation is for adults.

Is this trial a fit for you?

Likely a good fit

Adults 18 years or older scheduled for elective laparoscopic colorectal resection, with ASA I–III, who can provide informed consent.

Probably not a fit

Patients who do not experience a change in intraoperative conditions or those who have adverse reactions to oral laxatives may not benefit.

What this trial studies

This randomized pilot study compares oral laxative plus rectal enema bowel prep to rectal enema alone in adults undergoing elective laparoscopic colorectal resection. Intraoperative small-bowel diameters will be measured, and overall operative difficulty, bowel manipulation time, total operation time, need for extra ports, conversion to open surgery, intraoperative complications, blood loss, and early postoperative outcomes will be recorded. The goal is to determine if oral laxatives influence intraoperative exposure and technical challenges, informing future larger trials and bowel-preparation practice. The study uses a standardized measurement method for jejunal and ileal diameters and a surgeon-rated difficulty scale. This is a prospective randomized pilot to generate preliminary data rather than definitive outcomes.

Why it matters

Potential benefit: If successful, the findings could lead to improved understanding of bowel-prep practices that may reduce intraoperative difficulty in laparoscopic colorectal surgery.

How similar studies have gone: Prior work has explored bowel preparation effects on outcomes, but evidence specifically linking oral laxatives to intraoperative difficulty in laparoscopic colorectal surgery is limited and not yet conclusive.
