To analyze the safety and effectiveness of preoperative oral carbohydrates intake for patients undergoing endoscopic retrograde cholangiopancreatography (ERCP).

The clinical data of patients with various biliary diseases who received ERCP from March 2019 to August 2019 were retrospectively analyzed. They were divided into control group (n=63) and ERAS group (n=69) according to the different perioperative diet management concepts. The fasting time was 6 hours in the control group and 2 hours in the ERAS group respectively. 400 ml of oral carbohydrate was given in the ERAS group 2 hours before ERCP. SPSS21.0 software was used to analyze the data. The scores of postoperative fatigue, the scores of abdominal pain, the serological indicators at 18h after ERCP were expressed as mean±standard deviation and were examined by independent t test. The post-operative complications were examined by chisquare test, and Fisher exact probability method was used for correction. A P value of <0.05 was considered as statistically significant.

The scores of postoperative fatigue(2.4±1.6), the serum glucose at 18h after ERCP(5.3±1.5 mmol/L), the length(26.6±5.0 h) and the cost of stay (20897.9±2108.5 yuan) were lower in the ERAS group than those in the control group (P<0.05). There was no significant difference between two groups in the scores of abdominal pain, complication rate, serum amylase and leukocyte at 18h after ERCP (P>0.05).

Preoperative oral carbohydrates intake is safe for patients undergoing ERCP, which is beneficial to relieve perioperative fatigue and hunger, reduce insulin resistance, accelerate postoperative rehabilitation, shorten the length of stay and reduce the cost of hospitalization.
