Laparoscopic-Assisted Transversus Abdominus Plane Block Versus Intraperitoneal Irrigation of Local Anesthetic for Patients Undergoing Laparoscopic Cholecystectomy

This study is being performed to investigate whether the administration of local anaesthetic into the muscles in the abdomen or onto squirting the local anaesthetic onto the liver following keyhole gallbladder surgery is more beneficial in reducing pain post-operatively. Keyhole gallbladder surgery is typically performed under general anaesthesia (or while the patient is 'fully asleep'), however doctors use other pain relief types to reduce pain after the operation.
