简介：摘要Functional dyspepsia (FD) and gastroparesis are two common functional gastrointestinal diseases, affecting millions of people in both China and around the world. However, treatment options are limited and difficult due to multiple factors involved in their pathophysiologies. Therefore it is critically important to assess and understand pathophysiologies of these diseases before a treatment is given. In this minireview we provide updates on recent development in the pathophysiologies and treatments of FD and gastroparesis. In addition to common abnormalities in gastric accommodation, antral hypomotility and visceral hypersensitivity, FD has recently been reported to display a number of impairment in duodenal functions, such as low-grade inflammation and increased permeability. For gastroparesis, macrophages have recently been reported to play an important role in its pathophysiology. A brief overview on the assessment of pathophysiologies of FD and gastroparesis is also provided; pros and cons of clinically available methodologies as well as emerging methods are discussed. Finally, available treatment options for FD and gastroparesis are presented in this minireview, including authors′ opinions on the advantages and disadvantages of each therapy. Potential novel therapies for FD and gastroparesis, especially those associated with Traditional Chinese Medicine, are also introduced and discussed.

简介：AbstractBackground:Gastroparesis is a debilitating medical condition with limited treatment options. Gastric per-oral pyloromyotomy (G-POEM) has emerged as a promising treatment option with remarkable short-term clinical success shown in multiple studies. While the post-procedure protocol is not standardized across many centers, the majority of the centers observes these patients in the hospital after the procedure for monitoring. In this single-center prospective study, we evaluated the safety and feasibility of same day discharge after the G-POEM procedure.Methods:All the patients with refractory gastroparesis undergoing G-POEM from October 2019 to March 2020 were enrolled. A total of 25 patients were enrolled in the procedure. Based on the pre-defined criteria, patients were either discharged on the same day after the procedure or admitted to the hospital for further observation. The patient and procedure-related data were extracted from the chart review. Univariate analysis was performed (chi-squared test) on categorical variables after organizing categorical variables as numeric counts or percentages. The student t test was performed on continuous variables after reporting as mean and standard deviation. For analysis with a smaller sample size, Fisher exact and Mann–Whitney tests were used.Results:A total of 25 patients were enrolled. The technical success of G-POEM was 100% and clinical success was 80% (20/25) at 1-month follow-up. Of the 25 patients, 9 patients (36%) were discharged on the same day according to the procedure from the recovery unit. Of the remaining 16 patients who were admitted to the hospital post-procedure, 10 (40%) were admitted due to procedure-related causes while other admissions were either pre-planned or due to social reasons. The average Charlson comorbidity index was lower in the same day discharge group (P < 0.05). The number of patients requiring double myotomy was higher in the same day discharge group (P < 0.05). The overall complication rate of G-POEM in the study cohort was 12% (3/25) with all complications being mild without any severe adverse events.Conclusion:G-POEM is a safe and effective method of treatment for refractory GP with higher clinical success in short-term follow-up. The same day discharge after G-POEM is safe and feasible in >50% of patients with close periprocedural monitoring.
