Laparoscopic cholecystectomy: Low pressure vs standard pressure pneumoperitoneum

Abstract

Background: Laparoscopic cholecystectomy is quite common surgery performed now a days.
Objective: To compare the surgical outcomes in using low pressure vs standard pressure pneumo-peritoneum for
laparoscopic cholecystectomy.
Methodology: Study Design: Comparative cross sectional study. Settings: Department of Surgery, Sheikh Zayed
Hospital, Rahim Yar Khan. Duration of Study: January to October 2018. Total 70 cases (35 in each group) were
selected non-probability, consecutive sampling irrespective of gender and age more than 20 years undergoing
laparoscopic cholecystectomy. These cases were divided into two groups. The cases in group A underwent low
pressure and in group B, standard pressure of pneumo-peritoneum was employed. The surgery was done according to
the set protocol of cholecystectomy and post operatively these cases were assessed on the basis of pain on VAS (Visual
Analogue Score) and operative time counted from incision to closure in minutes. Data was analyzed by SPSS 23.
Results: In this study, out of total 70 cases; 35 were divided in each group. The mean age was 51.47±7.39 vs
50.23±8.18 years and mean duration of symptoms was 6.12±2.39 vs 7.11±4.29 months in group A and B respectively
with p= 0.91 and 0.78. There were 16 (45.71%) males in group A and 15 (4.86%) in group B with p= 0.67. Mean
operative time was 63.19±11.89 vs 74.77±10.59 minutes and pain on VAS was 1.49±0.37 vs 3.11±1.07 in group A and
B respectively with p values of 0.03 and 0.001.
Conclusion: Low pressure pneumo-peritoneum cholecystectomy is better than standard pressure both in terms
operative time and post operative pain.
