Effect of Low-pressure Pneumoperitoneum on Pain and Inflammation in Laparoscopic Cholecystectomy

Not Applicable

Completed

• Conditions: Pain; Pneumoperitoneum; Inflammatory Response

• Registration Number: NCT05530564
• Lead Sponsor: University of Jordan

Brief Summary

The purpose of this study is to assess the effect of low-pressure pneumoperitoneum on post operative pain and inflammation in patients undergoing elective laparoscopic cholecystectomy by comparing it to standard practice.

Detailed Description

After obtaining informed consent from eligible study participants. patients were randomized into one of two masked groups, labelled red and green. The red-label group was operated at standard-pressure pneumoperitoneum, while the green-label group was operated at low-pressure pneumoperitoneum. Baseline blood samples were obtained pre-operatively for ten inflammatory markers, patients' demographics and intra-operative details collected, then post-operative pain and change in inflammatory markers were followed.

Primary Outcome Measures

Name	Time	Method
assessment of pain with SPS-11 at 6hr post-op	pre-op to 6 hours post op	measure difference in pain on the 11-point short pain scale (SPS-11) at 6-hour post-op compared to baseline at pre-op, minimum score of 0 , maximun score of 10; = pain at 6 hour post op - pain at pre-op
change in IL-6	pre op to 24 hours post -op	measure differance of inflammatory marker from baseline; = baseline value- post op value (calculated in pg/mL) post-op collected at 24 hours from end of surgery

Secondary Outcome Measures

Name	Time	Method
assessment of difficulty of surgery	start to end of the study, 1 year	to measure difference in surgery difficulty between the two groups using a scale of 1; easy, 2; moderate, 3; difficult.; analysis done using Chi-square cross table on SPSS V 1.0.0.1406
assessment of difference in operation time	start to end of the study, 1 year	to look for difference in operation time between the two groups, calculated in minutes.; analysis done using Student's 2-tailed t-test on SPSS V 1.0.0.1406
