Postoperative gastrointestinal tract (GIT) dysfunction (POGD) and postoperative ileus (POI) are common symptoms resulting from small or large bowel surgery associated with extended hospitalizations, increase risk of infections and billions of dollars in health care costs. Open surgery is associated with higher gut surgical trauma / manipulation and worse outcomes compared to minimal invasive surgery. Robotic Surgery may offer added benefit to Colon Enhanced Recovery After Surgery (CERAS) protocols but do not solve the problem. Ultimately, a better understanding of the pathogenic mechanisms of POI and POGD can lead to prophylaxis and enhanced recovery after surgery. The impact of High Pressure Pneumoperitoneum and gut surgical manipulation on GIT dysfunction deserve further investigation.
