The primary aim of this randomized controlled prospective study (www.clinicaltrials.gov NCT00599144) was assessing effectiveness on pain control after videolaparoscopic cholecystectomy (VLC) of 0.5% Bupivacaine-soaked sheet of regenerated oxidized cellulose positioned in the gallbladder bed. We randomized in three equal groups 45 patients that underwent elective videolaparoscopic cholecystectomy: group A - Bupivacaine-soaked sheet of regenerated oxidized cellulose positioned in the gallbladder bed; group B - Bupivacaine infiltrated in the muscular fasciae of the trocars' seat; group C - control group, not using local anesthetic. Six and 24 hours after the intervention we recorded the type of the pain and its intensity, using a visual analog scale (VAS). We observed no statistically significant difference in pain intensity. Considering the type of pain, 55,56% of patients referred visceral pain, 62,22% parietal pain and 44,44% shoulder pain. Group A shows, at both endpoints, a statistically significant reduction (p < 0.05) of visceral and shoulder pain versus other groups. Moreover, the use of a local anesthetic significantly reduces the use of post-operative pain drugs, both for group A and B. A Bupivacaine-soaked sheet of regenerated oxidized cellulose positioned in the gallbladder bed post-VLC is safe and not economically demanding, and can give advantages in increasing post-operative comfort.
