Background: Minimal invasive surgery has many advantages. In order to maintain and control  pain, one of the most effective technique is Transversus abdominis plane (TAP) block technique. Aim of the study was to demonstrate the efficacy of laparoscopic guided transversus abdominis plane block in post-operative analgesia requirement in elective laparoscopic cholecystectomy.

Methods: It was a hospital based prospective interventional study. Sample size was calculated at 0.05 α error and 80% study power assuming mean difference of VAS score between TAP block +/A group  and TAP block- /B group is 1 and standard deviation of VAS score 1.3 among patients undergoing elective laparoscopic cholecystectomy.

Results: A total of 60 patients were enrolled in this study. The mean age of group A was 48.56 years and for group B was 43.53 years. In group A 80% patients were females and for group B 83.3% patients were females. There was significant difference in VAS score at immediate post operation, at 1 hour, at 6 hours, at 18 hours and at 24 hours as p value was <0.0001 for all these groups. The mean VAS score was recorded less in group A at all the time duration compared to group B.

Conclusions: With advantages like maximum safety, efficacy, potential for lower visceral injury risk and shorter operational time and other numerous advantages (decreased analgesic requirements, etc.)  laparoscopic-guided TAP block counts as an ideal abdominal field block in the patients.
