Abstract： Objective:To investigate the safety and efficacy of early oral feeding in the treatment of mild acute pancreatitis (MAP).Methods:Data of 100 MAP patients from April 2015 to June 2018 admitted in Department of General Surgery in Shanxi Bethune Hospital were collected. According to the time of food intake through the mouth, the patients were divided into early oral feeding group (food intake started when the symptoms of abdominal pain and abdominal distension were alleviated with gastrointestinal functional recovery, but serum amylase and lipase did not decrease to a level below 2 times of normal upper limits) and traditional oral feeding group (food intake started when the symptoms of abdominal pain and abdominal distension were alleviated with gastrointestinal functional recovery, but serum amylase and lipase decreased to a level below 2 times of normal upper limits), with 50 cases in each group. The incidence of abdominal pain or bloating, serum amylase, CRP, organ dysfunction, morbidity and mortality, and median length of hospital stay after eating were compared between the two groups.Results:There were no statistically significant differences on gender, age, etiology, abdominal pain and distension, increased serum amylase, increased blood CRP, and number of organ dysfunction cases between two groups, and there were no deaths in either group. However, the feeding time and length of hospital stay in the early oral feeding group were significantly shorter than those in the traditional oral feeding group, and the differences were statistically significant [(3.00±0.18)d versus (4.84±0.27)d, (8.24±0.33) D versus (9.00±0.26)d, both P<0.05]. Conclusions:Early oral feeding in MAP patients did not aggravate the disease, but helps to correct the nutritional status of the patients, with higher safety and effectiveness.
