ESP vs Subcostal TAP Block for Analgesia After Laparoscopic Cholecystectomy (ESP TAP)

Detaillierte Beschreibung
Postoperative pain remains a significant clinical concern after laparoscopic cholecystectomy despite the minimally invasive nature of the procedure. Inadequate analgesia may delay recovery, increase opioid consumption, and negatively affect patient satisfaction. Regional anesthesia techniques are increasingly incorporated into multimodal analgesia protocols to improve postoperative outcomes and reduce opioid requirements.
The erector spinae plane (ESP) block and the subcostal transversus abdominis plane (TAP) block are ultrasound-guided fascial plane blocks commonly used for abdominal surgery. While both techniques have demonstrated analgesic benefits, their comparative effectiveness in laparoscopic cholecystectomy remains uncertain. In particular, differences in visceral pain control, opioid-sparing effect, and shoulder pain incidence require further investigation.
This study is designed as a prospective, randomized, double-blind, parallel-group, clinical trial conducted at two tertiary care hospitals in Turkey. Eligible adult patients scheduled for elective laparoscopic cholecystectomy under general anesthesia will be randomly assigned to receive either bilateral ESP block or bilateral subcostal TAP block after induction of anesthesia. Standardized anesthesia and postoperative multimodal analgesia protocols will be applied in both groups to ensure comparability between centers.
The primary outcome measure is total opioid consumption within the first 24 postoperative hours, expressed as morphine equivalent dose. Secondary outcome measures include postoperative pain scores assessed using the Numerical Rating Scale (NRS), time to first analgesic request, incidence of shoulder pain, postoperative nausea and vomiting, and block-related complications.
Randomization will be performed using a computer-generated sequence, with allocation concealment ensured. Patients and postoperative outcome assessors will be blinded to group assignment. Data will be prospectively recorded and analyzed according to a predefined statistical analysis plan.
The findings of this study are expected to provide evidence-based guidance for optimizing regional analgesia strategies in laparoscopic cholecystectomy.

Intervention / Behandlung |
|---|---|
|
Experimental: Erector Spinae Plane Block
Patients in this arm will receive ultrasound-guided bilateral erector spinae plane block following induction of general anesthesia.
A standardized volume and concentration of local anesthetic will be administered at the appropriate thoracic level.
All patients will receive standardized intraoperative anesthesia and postoperative multimodal analgesia.
|
Ultrasound-guided bilateral erector spinae plane block will be performed after induction of general anesthesia.
The block will be administered at the appropriate thoracic vertebral level using a standardized volume and concentration of local anesthetic deposited in the fascial plane deep to the erector spinae muscle.
The procedure will be performed by experienced anesthesiologists under sterile conditions.
|
|
Experimental: Subcostal TAP Block
Patients in this arm will receive ultrasound-guided bilateral subcostal transversus abdominis plane block following induction of general anesthesia.
A standardized volume and concentration of local anesthetic will be administered.
All patients will receive standardized intraoperative anesthesia and postoperative multimodal analgesia.
|
Ultrasound-guided bilateral subcostal transversus abdominis plane block will be performed after induction of general anesthesia.
A standardized volume and concentration of local anesthetic will be injected into the fascial plane between the rectus abdominis and transversus abdominis muscles along the subcostal margin.
The procedure will be performed by experienced anesthesiologists under sterile conditions.
