Summary

Laparoscopic cholecystectomy is a common keyhole surgery to remove the gallbladder. Although the cuts are small, patients can still have significant pain and nausea after the operation, which may delay recovery and discharge. To improve comfort, doctors often use ultrasound-guided abdominal nerve blocks as part of multimodal pain management.

In this single-center, randomized controlled trial, adult patients scheduled for elective laparoscopic cholecystectomy will receive standard general anesthesia and be randomly assigned to one of two routinely used block techniques at the end of surgery: (1) a 4-point transversus abdominis plane (TAP) block, or (2) a combined bilateral rectus sheath block plus oblique subcostal TAP block. Both techniques are performed under ultrasound guidance while the patient is still asleep.

The main aim of the study is to compare the quality of recovery on the first day after surgery between the two groups, using a short questionnaire (QoR-15). Secondary aims are to compare pain scores, the need for additional pain medicine, and the frequency of postoperative nausea and vomiting between the groups during the first 24 hours. All other aspects of anesthesia and surgical care will follow standard hospital practice. Participation is not expected to add significant risk beyond that of routine anesthesia and surgery, as both block techniques are already commonly used in clinical practice.

Interventions

PROCEDURE

4-Point TAP (4QTAP) Group

4-Point TAP (4QTAP) Group: Ultrasound-guided 4-point transversus abdominis plane block will be performed at two subcostal and two lateral injection points. A total of 40 mL of 0.25% bupivacaine will be administered (10 mL at each point).

PROCEDURE

RSB + OSTAP Group

RSB + OSTAP Group: Ultrasound-guided bilateral rectus sheath block (two injection points) combined with bilateral oblique subcostal TAP block (two injection points) will be performed. A total of 40 mL of 0.25% bupivacaine will be administered (10 mL at each point).
