ObjectiveTo summarize and analyze the etiologies of recurrent acute pancreatitis (RAP) and then conclude the prevention and treatment strategies.MethodSearching relevant literatures of PubMed, CNKI, Wanfang data and other databases in recent years, the etiologies of RAP were analysed and reviewed, then the prevention and treatment strategies were developed.ResultsThe causes of RAP included abnormal function and structure of biliopancreatic duct, metabolic factors, bad living habits, genetic factors and so on. Then based on etiologies of RAP, prevention and treatment strategies of it were summarized.ConclusionsWith the developments of related researches and clinical diagnosis and treatment technologies, the etiologies of RAP are gradually revealed. It is of great significance to clarify the etiologies of RAP and make prevention and treatment strategies for reducing the recurrence of acute pancreatitis.
ObjectivesTo evaluate the effects of Pulmonary Embolism Response Team (PERT) on treatment strategies and long-term prognosis in patients with acute pulmonary embolism before and after the implementation of the first PERT in China. Methods The official start of PERT (July 2017) was took as the cut-off point, all APE patients who attended Beijing Anzhen Hospital of Capital Medical University one year before and after this cut-off time were included through the hospital electronic medical record system. The APE patients who received traditional treatment from July 5, 2016 to July 4, 2017 were recruited in the control group (Pre-PERT group), and the APE patients who received PERT mode treatment from July 5, 2017 to July 4, 2018 were recruited as the intervention group (Post-PERT group). Treatment methods during hospitalization were compared between the two groups. The patients were followed up for one year after discharge to evaluate their anticoagulant therapy, follow-up compliance and long-term prognosis. Results A total of 108 cases in the Pre-PERT group and 102 cases in the Post-PERT group were included. There was no significant statistical difference between the two groups in age and gender (both P>0.05). Anticoagulation therapy (87.3% vs. 81.5%, P=0.251), catheter-directed treatment (3.9% vs. 2.8%, P=0.644), inferior vena cava filters (1.0% vs. 1.9%, P=1.000), surgical embolectomy (2.0% vs. 0.9%, P=0.613), systemic thrombolysis (3.9% vs. 4.6%, P=0.582) were performed in both groups with no significant differences between the two groups. The use rate of rivaroxaban in the Post-PERT group was higher than that in the Pre-PERT group at one year of discharge, and the use rate of warfarin was lower than that of the Pre-PERT group (54.5% vs. 32.5%; 43.6% vs. 59.0%, P=0.043). The anticoagulation time of the Post-PERT group was longer than that of the Pre-PERT group (11.9 months vs. 10.3 months, P<0.001). The all-cause mortality within one year, hemorrhagic events and the rate of rehospitalization due to pulmonary embolism were not significantly different between the two groups, (10.4% vs. 8.6%), (14.3% vs. 14.8%), and (1.3% vs. 2.5%, χ2=3.453, P=0.485), respectively. Conclusions APE treatment was still dominated by anticoagulation and conventional treatment at the early stage of PERT implementation, and advanced treatment (catheter-directed treatment and surgical embolectomy) is improved, it showed an expanding trend after only one year of implementation although there was no statistical difference. At follow-up, there is no increase in one-year all-cause mortality and bleeding events with a slight increase in advanced treatment after PERT implementation.
