Comparison of Performing V-Notes Hysterectomy Under Spinal Anesthesia and General Anesthesia

Hysterectomy remains one of the most commonly performed surgical procedures in gynecology and is the second most frequently performed operation after cesarean section. Advances in minimally invasive surgery have led to the development of techniques aimed at reducing surgical trauma and improving patient outcomes. Vaginal natural orifice transluminal endoscopic surgery (V-NOTES) has emerged as a novel approach that combines the benefits of vaginal surgery and laparoscopy and is increasingly recognized as a safe and effective technique in gynecologic practice.

Despite improvements in surgical techniques, the choice of anesthesia remains a critical factor influencing perioperative outcomes. General anesthesia and regional (spinal) anesthesia are both widely used; however, comparative data regarding their effects in V-NOTES hysterectomy are limited.

This prospective observational study aims to compare V-NOTES hysterectomy performed under general anesthesia and regional (spinal) anesthesia. A total of 28 patients undergoing V-NOTES hysterectomy at our institution will be included and grouped according to the type of anesthesia administered.

Inclusion criteria include voluntary participation, provision of written informed consent, and preoperative evaluation confirming suitability for V-NOTES hysterectomy at the Çukurova University Balcalı Hospital, Department of Obstetrics and Gynecology. Exclusion criteria include a history of tubo-ovarian abscess, presence or history of deep endometriosis, suspected pelvic adhesions, nodules in the pouch of Douglas, a fixed uterus, sexual inactivity, and refusal to provide informed consent.

Preoperative data will include arterial blood pressure, vital signs, indication for hysterectomy, primary complaint, menopausal status, body mass index (BMI), gravidity, parity, comorbidities, number of previous surgeries, and American Society of Anesthesiologists (ASA) physical status classification. Intraoperative parameters will include additional surgical procedures, surgical comfort, duration of surgery, and type of anesthesia. Postoperative outcomes will include Visual Analog Scale (VAS) pain scores, headache, shoulder pain, nausea, vomiting, and length of hospital stay.
