Study Type

INTERVENTIONAL

Summary

This study is a prospective, randomized, double-blind, placebo-controlled clinical trial designed to evaluate the effect of paracervical block on early postoperative pain after vaginal natural orifice transluminal endoscopic surgery (vNOTES) uterosacral ligament suspension. Eligible patients undergoing vNOTES uterosacral ligament suspension for benign gynecologic indications will be randomly assigned in a 1:1 ratio to receive either 10 mL of 0.5% bupivacaine or 10 mL of normal saline as a paracervical injection during surgery. The primary outcome is postoperative pain assessed using the Visual Analog Scale (VAS) at 6 hours after surgery. Secondary outcomes include pain scores at multiple time points within 24 hours, total analgesic consumption, length of hospital stay, and patient satisfaction. The study aims to determine whether paracervical block provides clinically meaningful pain reduction in the early postoperative period following vNOTES procedures.

Interventions

DRUGBupivacaine

A total of 10 mL of 0.5% bupivacaine will be administered as a paraservical injection during vNOTES uterosacral ligament suspension. The solution will be prepared in identical syringes by independent personnel to maintain blinding.

DRUGNormal Saline

A total of 10 mL of 0.9% normal saline will be administered as a paraservical injection during vNOTES uterosacral ligament suspension. The solution will be prepared in identical syringes to ensure blinding.
