Backgrounds And AimOmentoplasty is frequently used as a safeguard in rectal cancer surgery for wrapping the anastomosis or filling up the pelvic cavity. The omentum is known for its infection defence and haemostatic and angiogenic properties. A disadvantage was hypothesized to be prolonged post-operative ileus, as omentoplasty interrupts the blood flow from an epiploic artery to the stomach.Materials And MethodsPatients who had had an uncomplicated surgical treatment for primary rectal cancer between January 2006 and March 2007 were included. Clinical parameters of post-operative ileus were collected and compared between procedures with a concomitant omentoplasty (n = 31) and without (n = 20).ResultsPatients needed their gastric tube significantly longer after omentoplasty than those without (3.9 vs 1.6 days, p < 0.001). Similar significant results were found for time to normal diet (p = 0.004), time to first discharge of faeces (p = 0.007), need for parenteral feeding (p = 0.036) and length of hospital stay (p = 0.008). Furthermore, there was a non-significant trend for more days to first discharge of air (3.4 vs 2.4 days, p = 0.165). There were no significant differences in patients' and procedure characteristics, except for more low anterior resections in the group without an omentoplasty (p < 0.001). None of these characteristics had any clinically relevant interference with the parameters of post-operative ileus.ConclusionA trend for prolonged post-operative ileus was found in patients who underwent an omentoplasty concomitant with their treatment for primary rectal cancer. When assessing the importance of omentoplasty in the future, post-operative ileus should be taken into account.
