The preventive effect of oral 76% Meglumine Diatrizoate for the postoperative ileus

After emergency surgery for intestinal obstruction caused by colorectal cancer, postoperative ileus (POI) is more likely to occur in the early-stage oral intake. POI incited the occurrence of postoperative complications and prolongs hospital stay. Reducing the occurrence of POI will Enhance Recovery After Surgery (ERAS). Aim: The aim of this study is to observe and evaluate the preventive effect of postoperative oral administration of 76% Meglumine Diatrizoate in reducing the incidence of POI and promoting intestinal absorption during the recovery of intestinal peristalsis in patients after intestinal obstruction surgery. Methods: From October 2018 to December 2021, 94 patients (47 vs 47) with intestinalobstruction were rolled. Patients with an ASA score of 4 or higher and gastrointestinal perforation with peritonitis were excluded. After 24 hours of surgery, the patients were divided into experimental group and control group disposed of with an opaque airtight envelope method, patient-side single blind. After intestinal peristalsis recovery (2.45 ± 0.62 d vs 2.60 ± 0.68 d, P > 0.05), the experimental group was given 76% Meglumine Diatrizoate 20 ml orally 9am and the control group was given 10% glucose 20 ml for three consecutive days. POI cases, the time taken to achieve full daily oral calorie and discharge days were counted. Results: The time required to achieve full daily oral calorie (11.04 ± 2.70 d vs 14.09 ± 3.74 d, p < 0.05), POI cases (10/47 vs 20/47, p < 0.05) and discharge days (14.00 ± 4.89 d vs 16.77 ± 5.94 d, p < 0.05) are significantly different between the two groups. Conclusions: Oral 76% Meglumine Diatrizoate is safe and effective, which can reduce the occurrence of POI, promote the recovery of intestinal absorption and shorten the length of hospital stay effectively.
