V-NOTES Versus Laparoscopy for Sterilization and Sexual Function (VNOTES-LS-FSFI)
Randomised Prospective Comparison of Sexual Function and Postoperative Recovery Following V-NOTES Versus Laparoscopic Bilateral Tubal Ligation and Salpingectomy
The goal of this randomized clinical trial is to compare two minimally invasive surgical approaches, transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) and conventional laparoscopy, in women undergoing bilateral tubal ligation or bilateral salpingectomy for sterilization.
The main questions it aims to answer are:
- Does V-NOTES have a different effect on postoperative sexual function compared with conventional laparoscopy?
- Does V-NOTES improve postoperative recovery, including pain, discharge time, and return to normal activity?
- What surgical or medical problems occur with each surgical approach?
- Researchers will compare V-NOTES with conventional laparoscopy to see whether one approach provides better postoperative sexual function and recovery outcomes after sterilization surgery.
Participants will:
- Undergo bilateral tubal ligation or bilateral salpingectomy using either V-NOTES or conventional laparoscopy.
- Complete sexual function questionnaires before surgery, at 6 weeks after surgery, and at 6 months after surgery.
- Be evaluated for postoperative pain, discharge time, return to normal activity, need for additional pain medication, complications, and perioperative laboratory changes.
- Attend scheduled postoperative follow-up visits at 6 weeks and 6 months after surgery.

Experimental: V-NOTES
Participants assigned to this arm will undergo sterilization surgery, either bilateral tubal ligation or bilateral salpingectomy, using the V-NOTES approach.
|
Transvaginal natural orifice transluminal endoscopic surgery (V-NOTES) will be used to perform bilateral tubal ligation or bilateral salpingectomy for sterilization.
In this approach, the peritoneal cavity will be accessed through a posterior vaginal fornix incision.
A single-port transvaginal access platform will be inserted, and the sterilization procedure will be completed under endoscopic visualization.
At the end of the procedure, the posterior vaginal fornix incision will be closed with absorbable suture.
|
|
Comparador activo: Laparoscopy
Participants in this arm will undergo bilateral tubal ligation or bilateral salpingectomy for sterilization using conventional laparoscopy.
|
Laparoscopy will be used to perform bilateral tubal ligation or bilateral salpingectomy for sterilization.
In this approach, the procedure will be performed through standard abdominal trocar access, including an umbilical trocar for laparoscope insertion and two additional lower abdominal trocars for surgical instruments.
The sterilization procedure will be completed under laparoscopic visualization, and the abdominal skin incisions will be closed at the end of the procedure.

Change in postoperative sexual function as assessed by the Female Sexual Function Index total score
Periodo de tiempo: Baseline, postoperative 6th week, and postoperative 6th month
|
The Female Sexual Function Index is a 19-item self-reported questionnaire that evaluates female sexual function across six domains: desire, arousal, lubrication, orgasm, satisfaction, and pain.
The total score ranges from 2.0 to 36.0, with higher scores indicating better sexual function.
The outcome will be reported as the change in total Female Sexual Function Index score from baseline to 6 weeks and 6 months after surgery.
A positive change indicates improvement in sexual function, whereas a negative change indicates worsening.

History of previous obstetric and non-obstetric surgery
Periodo de tiempo: Baseline/preoperative assessment
|
Previous surgical history will be assessed preoperatively using a structured case report form and review of the participant's medical records.
Obstetric surgery includes previous cesarean section or surgery for pregnancy-related indications.
Non-obstetric surgery includes previous gynecologic, abdominal, pelvic, or other surgical procedures unrelated to pregnancy.
The number and percentage of participants with previous surgery will be compared between the V-NOTES and laparoscopy groups.

Participants With Pre-existing Comorbidities Assessed by Medical History and Medical Record Review
Periodo de tiempo: Baseline
|
Pre-existing comorbidities will be assessed at baseline using participant medical history and medical record review.
Comorbidities will include chronic systemic diseases such as hypertension, diabetes mellitus, cardiovascular disease, thyroid disease, pulmonary disease, and other relevant chronic conditions.
The outcome will be reported as the number and percentage of participants with at least one pre-existing comorbidity in each study group.

Postoperative pain will be assessed using the Visual Analog Scale, an 11-point pain intensity scale ranging from 0 to 10, where 0 indicates no pain and 10 indicates the worst imaginable pain.
Higher scores indicate worse postoperative pain.
The mean Visual Analog Scale score will be compared between the V-NOTES and conventional laparoscopy groups.
