Summary

This study is designed to compare three different methods of pain control after laparoscopic gallbladder surgery (laparoscopic cholecystectomy). Although this surgery is minimally invasive, participants often experience different types of pain after the operation, such as pain at the incision site, pain inside the abdomen, and shoulder pain caused by the gas used during surgery.

The investigators will compare three commonly used pain relief techniques:

Local infiltration - injecting a numbing medicine (bupivacaine) into the gallbladder bed and at the sites where the surgical instruments are placed.

Erector spinae plane (ESP) block - an ultrasound-guided nerve block performed in the back to reduce both abdominal and incisional pain.

Intrathecal morphine - a very small dose of morphine given into the spinal fluid before surgery to provide long-lasting pain relief.

The goal is to determine which method provides the best pain control, reduces the need for opioid medications, and improves recovery after surgery.

Conditions

  • Postoperative Pain Management
  • Cholecystectomy, Laparoscopic

Interventions

DRUG

Bupivacaine Infiltration

After removal of the gallbladder, 40 mL of 0.25% bupivacaine will be applied to the gallbladder bed with a sterile sponge for 10-15 minutes. At the end of the surgery, 15 mL of 0.25% bupivacaine will be infiltrated into trocar insertion sites (5 mL umbilical port, 5 mL epigastric port, 5 mL each auxiliary port).

PROCEDURE

Erector Spinae Plane Block

Before induction of anesthesia, a bilateral ultrasound-guided erector spinae plane block will be performed at the T7 transverse process level. A total of 40 mL of 0.25% bupivacaine will be injected (20 mL per side) using an in-plane technique under ultrasound guidance.

DRUG

Intrathecal Morphine

With the patient in the sitting position, a 27-gauge spinal needle will be inserted at the L3-L4 interspace. A dose of 100 mcg morphine will be administered intrathecally before induction of anesthesia.
