About this trial
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.

Treatments tested in this trial
Bupivacaine
DrugA 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.
Normal Saline
DrugA 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.
Treatment groups
Trial outcomes
Primary outcomes
Postoperative Pain Score at 6 Hours
Postoperative pain intensity assessed using a 10-cm Visual Analog Scale (VAS) ranging from 0 (no pain) to 10 (worst imaginable pain). Higher scores represent greater pain intensity.
Secondary outcomes
Postoperative Pain Scores Within 24 Hours
Postoperative pain intensity assessed using a 10-cm Visual Analog Scale (VAS) ranging from 0 (no pain) to 10 (worst imaginable pain). Pain scores will be recorded at postoperative hours 0 (upon arrival in recovery room), 1, 2, 4, 12, and 24.
Total Analgesic Consumption
Total cumulative dose of rescue analgesic medication administered postoperatively, recorded in milligrams (mg) and converted to morphine-equivalent dose when applicable. Higher values indicate greater analgesic requirement.
Patient Satisfaction
Patient-reported satisfaction with postoperative pain control assessed using a 10-point Numeric Rating Scale (0 = not satisfied at all; 10 = completely satisfied). Higher scores represent greater satisfaction.
Length of Hospital Stay
Duration of hospitalization measured in days from the date of surgery until discharge.
