vNOTES - Short Notes (MS OBG)

Definition

History

• NOTES concept emerged in early 2000s for transgastric, transvaginal, transcolonic, and transesophageal access to the peritoneal cavity (general surgery origin - e.g., transvaginal cholecystectomy).
• First gynecological application: transvaginal NOTES hysterectomy in 2010, followed by myomectomy and oophorectomy.
• Modern vNOTES popularized largely through the work of Baekelandt and colleagues (Belgium), with dedicated single-port access devices developed around 2012 onward.

Basic Principle / Technique

1. A colpotomy (vaginal incision) is made, similar to conventional vaginal surgery, to enter the peritoneal cavity (anterior and/or posterior colpotomy).
2. A specialized single-port access device (e.g., GelPOINT V-Path, VUsion) is inserted through the vaginal opening, creating a pneumoperitoneum seal.
3. Standard laparoscopic instruments and a camera are introduced through the port, and the procedure (hysterectomy, adnexal surgery, myomectomy, prolapse repair) is performed under endoscopic vision - essentially "laparoscopy performed transvaginally."
4. The uterus (when present) can be used as a traction point for triangulation, which is closer to the instruments than in transabdominal laparoscopy.
5. Specimen retrieval and closure are done through the same vaginal port; no abdominal incisions are required.

Indications

• Total/subtotal hysterectomy for benign disease
• Adnexal surgery (oophorectomy, salpingectomy, cystectomy)
• Myomectomy
• Pelvic organ prolapse repair (sacrocolpopexy variants)
• Selected gynecologic oncology procedures (staging, lymph node assessment) - still under evaluation
• Especially useful in patients with multiple prior abdominal surgeries (avoids abdominal wall injury, port-site hernia, nerve entrapment risk)

Contraindications

• Lack of vaginal access (virginal/narrow vagina, severe vaginal stenosis)
• Large uterine size beyond safe vaginal morcellation limits (relative)
• Extensive pelvic adhesions obliterating the pouch of Douglas (relative, technique/experience-dependent)
• Suspected malignancy with need for extensive abdominal exploration (evolving indication)
• Active pelvic infection

Advantages (over conventional laparoscopy/open surgery)

• No visible abdominal scars, better cosmesis
• Less postoperative pain and reduced analgesic requirement
• Shorter operative time in several series
• Larger, less rigid colpotomy opening compared to abdominal mini-incisions - target tissue closer to the port, less instrument clashing
• Avoids abdominal wall complications (port-site hernia, nerve entrapment) - useful in patients with multiple prior laparotomies
• Faster recovery and shorter hospital stay
• Smoke/pneumoperitoneum gas vents into upper abdomen away from the operative field

Disadvantages / Limitations

• Steep learning curve; requires proficiency in both vaginal surgery and laparoscopy
• Limited working space and instrument triangulation compared to standard laparoscopy
• Risk of bladder, bowel, ureteric injury during colpotomy and port placement
• Not suitable for all patients (nulliparous/narrow vagina, large adnexal masses)
• Still an evolving technique - fewer surgeons trained, limited long-term oncologic outcome data

Evidence Summary

• A systematic review of vNOTES in benign gynecology (adnexal surgery, myomectomy, prolapse) found it comparable or superior to laparoscopy in operative time and pain outcomes (PMID: 39647776).
• A systematic review of vNOTES in gynecologic oncology procedures suggests feasibility but calls for more robust data before widespread oncologic adoption (PMID: 41078049).
• A meta-analysis on vNOTES for ovarian cystectomy showed benefits in operative time and length of stay versus laparoscopy (PMID: 40712463).
