Objective:To analyze the psychological stress of infertile patients after COVID-19 epidemic and its related factors by Chinese version of the perceived stress scale (CPSS).Method:The basic information, reproductive history, impact of the epidemic, psychological status of patients undergoing assisted reproductive technology at the General Hospital of Northern Theater Command from March 29, 2021 to April 29, 2021 were collected by questionnaire. According to CPSS, group comparison and correlation analysis were used to explore factors related to patients' psychological stress.Results:A total of 251 valid questionnaires were received. The average CPSS score of the patients was 22.43±7.07. During the epidemic, about 33.86% (85/251) of the infertility patients postponed the fertilization plan; there were significant differences in the psychological stress among patients of different genders, occupations, and postponed fertilization plans at different stages of fertilization ( P=0.001, P=0.005, P=0.002). There was no significant difference in CPSS score between infertile patients who delayed treatment or not ( P>0.05). Correlation analysis showed that the perceived stress of patients was negatively correlated with their age, income, and delay duration ( r=-0.192, P=0.002; r=-0.323, P=0.001; r=-0.282, P=0.009). Among all patients who delayed treatment, patients with higher CPSS score would restart treatment sooner; most of the infertile patients knew little about the vaccine. Conclusion:The COVID-19 epidemic has caused a certain impact on the psychological pressure of infertile couples who accepted treatment in our hospital. The psychological care for infertile patients is particularly important. In the future, in order to dispel the doubts of infertile patients about the vaccine, we should pay attention to the correct scientific promotion of the COVID-19 vaccine during the treatment process.

A postoperative follow-up study, through the subcutaneouslyplaced afferent loop of a choledocho-jejunostomy by retrograde cholangiography and/or choledochoscopy in 116 patients with intrahepatic lithiasis, was made. The retained stones, worms, ductal strictures, or suppurative cholangitis were found in 41 cases over a period of one month to six years postoperatively. All these conditions required further management and some even emergency intervention. The patients were all treated successfully by a Dormia basket or other instruments through this conduit with exception of four failures, the overall success rate was 90%. It is suggested that this type of Roux-en-y choledocho-jejunostomy is recommended in the cases with intrahepatic lithiasis which can provide a permanent access from outside to thebiliary tree and appropriate instruments can be passed through this route for diagnostic and therapeutic interventions such as postoperative cholangiography, retained stones removal, and biliary drainage. We believe this route has some advantages over the T-tube tract for non- operative management of intrahepatic residual lesions.
