简要总结

Intra-abdominal pressure (IAP) needed to create sufficient workspace during laparoscopic surgery affects the surrounding organs with ischemia-reperfusion injury and a systemic immune response. This effect is related to postoperative recovery, pain scores, opioid consumption, bowel function recovery, morbidity and possibly mortality. In clinical practice standard pressures of 12-16mmHg are applied instead of the lowest possible IAP, but accumulating evidence shows lower pressure pneumoperitoneum (PNP) (6-8mmHg) to be non-compromising for sufficient workspace, when combined with deep neuromuscular blockade (NMB) in a vast majority of patients. Therefore, low impact laparoscopy, meaning low pressure PNP facilitated by deep NMB, could be a valuable addition to Enhanced Recovery After Surgery (ERAS) Protocols.

The use of low pressure PNP may also reduce hypoxic injury and the release of DAMPs and thereby contributing to a better preservation of innate immune function which may help to reduce the risk of infectious complications.

The participants will be randomly assigned to one of the experimental groups with low impact laparoscopy or one of the control groups with standard laparoscopy.

This effect is related to postoperative recovery, pain scores, opioid consumption, bowel function recovery, morbidity and possibly mortality. Therefore, low impact laparoscopy, meaning low pressure PNP facilitated by deep NMB, could be a valuable addition to Enhanced Recovery After Surgery (ERAS) Protocols.

The use of low pressure PNP may also reduce hypoxic injury and the release of DAMPs and thereby contributing to a better preservation of innate immune function which may help to reduce the risk of infectious complications.

The participants will be randomly assigned to the experimental group 1: low impact laparoscopy (low pressure (8 mmHg) and deep NMB (PTC 1-2)); 8 mmHg IAP after trocar introduction for perfusion measurement or the experimental group 2: low impact laparoscopy (low pressure (8 mmHg) and deep NMB (PTC 1-2)); 12 mmHg IAP after trocar introduction for perfusion measurement, or control group 1: standard laparoscopy (standard pressure (12 mmHg) and moderate NMB (TOF 1-2)); 8 mmHg IAP after trocar introduction for perfusion measurement, or control group 2: standard laparoscopy (standard pressure (12 mmHg) and moderate NMB (TOF 1-2)); 12 mmHg IAP after trocar introduction for perfusion measurement.

ICG injection will take place with starting pressure to quantify parietal peritoneum perfusion, and a parietal peritoneal biopsy will be taken. At the end of surgery, a second parietal peritoneum biopsy will be taken.

NB: After introduction of the camera trocar, insufflation of carbon dioxide is titrated to an IAP of 8mmHg in group A and C, and 14 mmHg in group B and D. After placement of the last trocar the injection of ICG and video registration of peritoneum will take place, and a peritoneal biopsy will be taken. There after surgery will take place with an IAP of 14mmHg in the control groups (C and D), and an IAP of 8mmHg in the experimental groups (A and B). In the control groups (C and D)
