5. Study Description

Brief Summary
Substudy of the RECOVER trial (a randomised controlled trial comparing the effect of low pressure pneumoperitoneum with deep neuromuscular block versus normal pressure pneumoperitoneum with moderate neuromuscular block during laparoscopic colorectal surgery on early quality of recovery) investigating innate immune homeostasis after laparoscopic colorectal surgery.
Detailed Description
Rationale: increased intra-abdominal pressure can cause peritoneal mesothelial cell injury either directly or by compression of the capillary vessels, causing a variable degree of ischemia reperfusion injury. The immune system can identify damage to host cells by recognising Danger-Associated Molecular Patterns (DAMPs) that are released upon cell death in an uncontrolled fashion, such as during surgical trauma. DAMPs elicit an immune response similar to the response to invading pathogens and induce an anti-inflammatory immune response strongly related to postoperative recovery, infectious complications and mortality. Low pressure PNP is associated with lower levels of serum pro- and anti-inflammatory cytokines and better preservation of innate immune function. Objective: to establish the relationship between the use of low pressure pneumoperitoneum with deep neuromuscular blockade and innate immune function after laparoscopic colorectal surgery. Study design: a multi-center, blinded, randomized controlled clinical trial. Study population: adult individuals scheduled for laparoscopic colorectal surgery with a primary colonic anastomosis. Intervention: participants will be randomly assigned in a 1:1 fashion to either the experimental group (group A): low pressure PNP (8 mmHg) with deep NMB (PTC 1-2) or the control group (group B): normal pressure PNP (12 mmHg) with moderate NMB (TOF count 1-2). Primary endpoint: mononuclear cell responsiveness ex-vivo as reflected by TNFα release upon LPS stimulation. Secondary endpoints: mononuclear cell responsiveness ex-vivo as reflected by IL-6, IL-10 and IL-1beta release upon LPS stimulation. Peritoneal mesothelial hypoxia as reflected by peritoneal HIF1α mRNA expression, histological peritoneal mesothelial cell injury and plasma levels of DAMPs and cytokines.
