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

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.

Early Versus Delayed Ileostomy Closure Following Bowel Surgery

Temporary ileostomy is commonly created following bowel surgery to protect distal anastomoses and reduce the consequences of anastomotic leakage. However, the optimal timing for ileostomy closure remains controversial. Early closure may improve quality of life and reduce stoma-related complications, whereas delayed closure may allow better recovery but prolong stoma-related morbidity and hospital care. This randomized controlled trial aims to compare the mean post-operative hospital stay between early (within 8 weeks) and delayed (after 8 weeks) ileostomy closure following bowel surgery. Sixty eligible patients will be randomized equally into two groups. The findings will help determine the optimal timing of ileostomy reversal and may improve patient outcomes while reducing healthcare utilization.
