Result: The mean ± standard deviation of age of the patients from Group A, Group B and Group C is 40.2 ± 12.1 years, 43.7 ± 13.6 years and 49.4 ± 17.3 years respectively. The age range for patients enrolled in the study was between 16 – 80, mean age being 42.78 years. 1) Values are Mean and standard deviation (SD). P-values by One-way analysis of variance (ANOVA) with Post-Hoc Boferroni’s test for multiple group comparisons. P-value <0.05 is considered to be statistically significant. *P-value<0.05, **P-value<0.01, ***P-value<0.001, NS: Statistically Non-Significant. Postoperative shoulder tip pain was present in all three groups, 4 patients group A, 3 patients in group B & 4 patients in the control group complained of shoulder tip pain postoperatively. However chi square test yielded that the results were insignificant with a p value = 0.392

Conclusion: The present study was conducted on a group of 90 patients diagnosed to have symptomatic cholelithiasis and who underwent elective laparoscopic cholecystectomy under General Anaesthesia at the department of surgery. Majority of patients were females (73.4%). To conclude, Instillation of bupivacaine intra-peritoneally and at port sites in laparoscopic cholecystectomy irrespective of the timing of instillation is an effective method of achieving pain control in the post-operative period as long as 12 hours after surgery.
