Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Our hypothesis is that in laparoscopic cholecystectomy, bilateral TAP blocks will reduce postoperative pain scores when compared to conventional postoperative pain control with local infiltration of trochar insertion sites.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
TAP Block
Patient will received bilateral ultrasound-guided TAP block with total of 30 ml of ropivacaine 0.5% after induction of general anesthesia
TAP Block
Patient will received bilateral ultrasound-guided TAP block with total of 30 ml of ropivacaine 0.5% after induction of general anesthesia
Local infiltration
20 ml of Ropivacaine 0.5% will be injected at port sites after induction of general anesthesia. 7 ml each for 10 mm ports, 3 ml each of 5 mm ports
Local infiltration
20 ml of Ropivacaine 0.5% will be injected at port sites after induction of general anesthesia. 7 ml each for 10 mm ports, 3 ml each of 5 mm ports

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
2. American Society of Anesthesiology Physical Status I, II or III
3. Inpatients scheduled to undergo laparoscopic cholecystectomy at Ben Taub General Hospital
Exclusion Criteria
2. Scheduled for ambulatory surgery
3. Renal dysfunction (Serum Cr \> 1.2) - excluded due to potential altered metabolism of anesthetic and pain medications
4. Coagulopathy or anticoagulation - increased risk of bleeding from nerve block injection
5. Allergy or contraindication to any of the study medications or anesthetic agents
6. Chronic opioid analgesic use at home - excluded due to potential difficulty in assessing pain caused by the procedure alone
7. Patient inability to properly describe postoperative pain to investigators (language barrier, dementia, delirium, psychiatric disorder)
8. Pregnancy
9. Prisoners
10. Patient or surgeon refusal
