* Preoperative assessment: Patients who fulfill inclusion criteria will be evaluated by medical history, physical examination and clinical laboratory tests which are a complete blood picture (CBC), kidney function tests, liver function tests, international normalized ratio(INR), prothrombin time(PT), and chest X-Ray. An electrocardiograph (ECG) will be done for patients above 40 years old. Patients will be prepared by 8 hours of preoperative fasting, receiving a tablet of Omeprazole 20 mg and Alprazolam 0.5 mg at bedtime the day before surgery. * All patients will be educated about the standard Numerical Rating Scale (NRS) for pain score of 0-10 (0 = no pain, 10 = the most severe pain) during preanesthetic evaluation visit. * In our study, 70 patients will be randomly divided into two equal groups, with 35 pt. in each. Spinal anesthesia will be performed at L3-L4 with 3.5 ml of hyper¬baric bupivacaine 0.5% and 0.25 ml normal saline only for the E group or 0.1 mg morphine in 0.25 ml normal saline for the M group (9). Group {E} will receive ESPB on the ipsilateral side of the surgery then 3.5 ml of bupivacaine 0.5% and 0.25 ml of normal saline intrathecal.
