Comparing Postoperative Pain Following COX-2 and Prostanoids Expression

Not Applicable
Conditions
Female Genital Disease
Interventions
Drug: COX-2 inhibitor
Drug: Placebo Oral Tablet
Procedure: Preoperative peritoneal biopsy
Procedure: Single-port laparoscopic surgery
Procedure: Postoperative peritoneal biopsy
Registration Number
NCT03391570
Lead Sponsor
Seoul National University Hospital
Brief Summary

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
