Short-term effects of gallbladder perforations during laparoscopic cholecystectomy on respiratory mechanics and depth of pain

Abstract

Background: In this study the effects of gallbladder perforations during laparoscopic cholecystectomy on respiratory mechanics and depth of pain in the postoperative period was evaluated.

Methods: Between April 2004 and February 2006 we planned to perform 179 laparoscopic cholecystectomies. One hundred of these patients were included in this study. Patients were divided into two groups: group 1 with gallbladder perforation during the operation and group 2 without perforation. Two groups were compared regarding age, gender, comorbidities, mean hospital stay, respiratory function tests, and postoperative pain scores.

Results: Gallbladder perforation occurred in 33 patients (33%). The male-to-female ratio of group I was 5/28. In group 2 the male-to-female ratio was 12/55. Age and perforation had a significant correlation according to Spearman's correlation test (p < 0.05, r = 0.211). Regarding respiratory function tests and arterial blood gases analysis, there was a significant decrease in both groups postoperatively but perforation had no effect on them. No statistically significant difference occurred regarding mean hospital stay and postoperative visual pain scores (p > 0.05).

Conclusion: Gallbladder perforation during laparoscopic cholecystectomy had no effect on postoperative respiratory mechanics and depth of pain.
