Effectiveness of M-TAPA nerve block for pain relief after laparoscopic hysterectomy
Official title: Effectiveness of Modified-Thoracoabdominal Nerve Block With Perichondrial Approach (M-TAPA) on Postoperative Pain Relief in Laparoscopic Hysterectomy Surgery: A Prospective, Randomized, Double-Blind, Controlled Study
Run by Istinye University · NCT07483190 · Data updated 2026-11-12
This study tests whether the M-TAPA nerve block before surgery can reduce opioid use and pain after laparoscopic hysterectomy compared with standard pain care.

Is this trial a fit for you?
✓Likely a good fit
Adults 18–70 years scheduled for elective laparoscopic hysterectomy with ASA I–III, eligible for regional anesthesia, and who consent to participate.
✕Probably not a fit
Patients with contraindications to regional anesthesia, BMIs above 35, or those who do not respond to the block may not see a benefit.

What this trial studies
This interventional study assigns adults undergoing elective laparoscopic hysterectomy to receive either the Modified-Thoracoabdominal Nerve Block through a Perichondrial Approach (M-TAPA) with bupivacaine before surgery or standard postoperative pain management without the block. The main outcome is total morphine consumption in the first 24 hours after surgery, with secondary outcomes including pain scores, time to first analgesic request, patient satisfaction, and side effects such as nausea. Participants are adults 18 to 70 years old with ASA I–III, without significant hepatic/renal disease, coagulation disorders, or allergies to local anesthetics, and who consent to regional anesthesia. The trial is conducted at Istinye University Liv Hospital Bahcesehir in Istanbul, sponsored by Istinye University.
Why it matters
Potential benefit: If successful, patients may experience less opioid use and better pain control after surgery, potentially speeding recovery.
How similar studies have gone: Prior regional anesthesia approaches have shown pain reductions in similar abdominal surgeries, though this specific M-TAPA approach is being tested for this procedure.
