Procedure: standard-pressure pneumoperitoneum
Registration Number
NCT04779515
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
NameTimeMethod
change from baseline in ESR value at 24hr post opbaseline and 24 hours post-op

calculate the rise in erythrocyte sedimentation rate value as inflammatory marker post-op in millimeters per hour.

change = (post-op ESR) - (baseline ESR)

change from baseline in TNF level at 24hr post opbaseline and 24 hours post-op

calculate the rise in tumor necrosis factor alpha level as inflammatory marker post-op in pg/mL change = (post-op TNF) - (baseline TNF)

change from baseline in WBC count at 24hr post opbaseline and 24 hours post-op

calculate the rise in white blood cycles count as inflammatory marker post-op in 1000 cells per cubic millimeter of blood.

change = (post-op WBC count) - (baseline WBC count)

change from baseline in pain on the 11-point short pain scale (SPS-11) at hour 12 post-opbaseline and 12 hours post-op

the SPS-11 is a validated, self-reported numeric instrument assessing pain intensity, ranging from 0 to 10; where 0 is no pain, and 10 is the worst pain felt ever.

change = (pain score at 12-hr post-op) - (baseline pain score assessed at 6-hr post-op)

change from baseline in pain on the 11-point short pain scale (SPS-11) at hour 24 post-opbaseline and 24 hours post-op

the SPS-11 is a validated, self-reported numeric instrument assessing pain intensity, ranging from 0 to 10; where 0 is no pain, and 10 is the worst pain felt ever.

change = (pain score at 24-hr post-op) - (baseline pain score assessed at 6-hr post-op)

change from baseline in cortisol level at 4hr post opbaseline and 4 hours post-op

calculate the rise in cortisol level as inflammatory marker post-op in nmol/L change = (post-op cortisol ) - (baseline cortisol )

change from baseline in pain on the 11-point short pain scale (SPS-11) at day 7 post-opbaseline and 7 days post-op

the SPS-11 is a validated, self-reported numeric instrument assessing pain intensity, ranging from 0 to 10; where 0 is no pain, and 10 is the worst pain felt ever.

change = (pain score at post-op day 7) - (baseline pain score assessed at 6-hr post-op)

change from baseline in Plt count at 24hr post opbaseline and 24 hours post-op

calculate the rise in platelets count as inflammatory marker post-op in × 10\^9/L of blood change = (post-op Plt count) - (baseline Plt count)

change from baseline in CRP level at 24hr post opbaseline and 24 hours post-op

calculate the rise in C reactive protein level as inflammatory marker post-op in mg/L change = (post-op CRP) - (baseline CRP)

change from baseline in IL-6 level at 24hr post opbaseline and 24 hours post-op

calculate the rise in interleukin 6 level as inflammatory marker post-op in pg/mL change = (post-op IL-6) - (baseline IL-6)

change from baseline in IL-1 level at 24hr post opbaseline and 24 hours post-op

calculate the rise in interleukin 1 level as inflammatory marker post-op in pg/mL change = (post-op IL-1) - (baseline IL-1)

change from baseline in Alb level at 24hr post opbaseline and 24 hours post-op

calculate the drop in albumin level as inflammatory marker post-op in g/dL change = (baseline Alb) - (post-op baseline Alb)

change from baseline in IL-17 level at 24hr post opbaseline and 24 hours post-op

calculate the rise in interleukin 17 level as inflammatory marker post-op in pg/mL change = (post-op IL-17) - (baseline IL-17)

Secondary Outcome Measures
NameTimeMethod
Difference in surgery time among two groupsthrough study completion, an average of 1 year

assessing difference in insufflation time calculated in minutes between low and standard pressure pneumoperitoneum groups.

insufflation time was calculated from time of creation of pneumoperitoneum to deflation of the abdomen.

Difference assessed by calculating average between groups

Difference in surgery difficulty level among two groupsthrough study completion, an average of 1 year

assessing level of surgery difficulty between low and standard pressure pneumoperitoneum groups.

Difficulty was self reported by operating surgeon as easy (score=1), moderate (score=2), or difficult (score=3).

Difference assessed by calculating average between groups
