Comparing Postoperative Pain Following COX-2 and Prostanoids Expression (COX2RCT)
December 30, 2017 updated by: Hee Seung Kim, Seoul National University Hospital
A Prospective Randomized Clinical Trial for Comparing Postoperative Pain Following COX-2 and Prostanoids Expression in Women Who Underwent Laparoscopic Surgery for Female Genital Disease
The purpose of this study is to compare postoperative pain following COX-2 and prostanoids expression in women who underwent laparoscopic surgery for female genital disease in order to evaluate the effect of COX-2 on local inflammation, COX-2 and prostanoids expression followed by exposure time to carbon dioxide(CO2) gas, and degree of postoperative pain.

Detailed Description
In women who underwent laparoscopic surgery for female genital disease, the effect of COX-2 on local inflammation was assessed by randomization, using the COX-2 inhibitor celecoxib and placebo, comparative evaluation of expression of COX-2 and prostanoids by pre/postoperative peritoneal biopsy and postoperative pain depending on gas exposure time
