Erector Spina Plane Block Versus Modified Thoracoabdominal Nerve Block After Laparoscopic Cholecystectomy

Condition(s) studied

Investigational drug(s) / intervention(s)

bilateral ESP block: bilateral ESP block with injection of 20 ml 0.25% bupivacaine.

bilateral M-TAPA block: bilateral M-TAPA block with injection of 20 ml of 0.25% bupivacaine.

Study summary

direct comparisons between ESPB and M-TAPA for postoperative analgesia after LC remain limited. This is an important area of clinical interest because the two blocks differ significantly in their anatomical targets, mechanism of analgesia, and likely dermatomal coverage. The ESPB provides analgesia through paravertebral spread affecting both dorsal and ventral rami, thereby offering posterior and visceral pain relief, whereas M-TAPA directly targets the thoracoabdominal nerves, resulting in better anterior and lateral abdominal wall analgesia. Understanding which technique offers superior or more balanced analgesia could help to optimise regional anaesthesia strategies in LC and to improve patient outcomes.
