Summary
Brief summary (as posted)
The study design is a prospective randomized, double-blind, controlled trial of patients who are due to have elective laparoscopic colorectal surgery in Ramathibodhi Hospital. The primary objective is to measure pain scores (Visual Analog Scale) in the postoperative period. The secondary objective is to compare the VAS scores between the two types of technique used for specimen retrieval incision.After approval by the ethics committee, patients scheduled for elective laparoscopic colorectal surgery under general anesthesia who are eligible for inclusion criteria were recruited for this study after informed consent by surgical residents or surgical staff at the Outpatient Department (OPD).
