Objective To systemically review andquantify the incidence of oral feeding intolerance in acute pancreatitis. Methods Randomized controlled trials that reported the oral feeding intolerance rates of acute pancreatitis were searchedfrom PubMed, EMBASE, Medline, Cochrane Library, WanFang, CNKI, CMCC and VIP dal,abase wilh the" Acute pancreatitis " " Feeding intolerance" " Incidence" " Meta- analysis "from January 2002 to May 2017. Date were analyzed by using R 3. 4. 0 software. The heterogeneity of data were analyzed using 12test. Results Eleven randomized controlled trials including 658 cases were enrolled in Meta-analysis. The incidence of oral feeding of intolerance was 12. 2% . The result of subgroup analysis showed that there were no significant difference in the incidence of oral feeding intolerance when region, sample size and published year were taken into analysis (P > 0. 05). The oral feeding intolerance rate of mild acute pancreatitis was lower than that when moderately severe acute pancreatitis and severe acute pancreatitis were, included (8. 2% and 19. 9% , respectively; P = 0. 002 7). Conclusion Oral feeding intolerance affects approximately l in 8 patients with acute pancreatitis. The incidence of oral feeding intolerance of patients with severe acute pancreatitis is higher than that of patients with mild acute pancreatitis

Objective:To summarize the clinical experience in treating acute superior mesenteric artery embolization with intestinal necrosis.Methods:Clinical data, surgical methods, complications and 30-day follow-up of patients with acute superior mesenteric artery embolization and intestinal necrosis admitted at Xijing Hospital of Air Force Military Medical University from Jan 2008 to Dec 2020 were retrospectively analyzed.Results:A total of 46 patients were included. The 30-day overall mortality rate was 19.6%, and that of those treated by enterostomy after enterectomy was 12.1%, and that was 38.5% in those undergoing primary entero-anastomosis after enterectomy. Univariate analysis showed that rebound pain was positive ( P=0.025), MAP was higher than 105mmHg ( P=0.04), heart rate was less than 120 beats/min ( P=0.04), and Fullen intestinal ischemia grade ( P=0.03) was significantly related to survival rates. Conclusions:Rebound pain, MAP, heart rate, Fullen grade, and surgical methods significantly affect the prognosis of patients. More patients survive with intestinal resection and enterostomy than those with intestinal resection and immediate anastomosis.
