Inadequately managed acute pain following abdominal surgery originates from somatic pain signals in the abdominal wall and is linked to various unfavorable postoperative outcomes. These consequences encompass patient distress, respiratory complications, delirium, myocardial ischemia, extended hospital stays, an elevated risk of chronic pain, heightened analgesic consumption, delayed bowel function, and an increased need for rescue analgesics.

This study aims to assess the postoperative analgesic efficacy of ultrasound-guided Transversus Abdominis Plane (TAP) block using oblique subcostal and posterior approaches in hepatectomy.

Pain control is vital to achieve enhanced recovery after abdominal surgeries . TAP block had been demonstrated to improve pain related outcomes after abdominal surgeries.

Postoperative pain management for patients undergoing hepatic resection is a challenge due to the risk of perioperative liver dysfunction.TAP block is a promising regional analgesic technique. This study aimed to evaluate the effect of US-guided subcostal approach versus combination of both subcostal and posterior approaches of TAP block

The patients will be randomly divided into two groups :

group A will recieve oblique subcostal TAP block and group B will recieve both subcostal and posterior TAP block .
