To investigate the clinical outcomes of endoscopic diagnosis and treatment in patients with duodenal variceal bleeding, a retrospective analysis was conducted on clinical data of patients with ectopic duodenal variceal bleeding diagnosed and treated endoscopically at the Digestive Endoscopy Center of Beijing Friendship Hospital, Capital Medical University, from August 2011 to December 2024. Five male patients (mean age 50.4 years) were included. Etiologies included alcohol-related cirrhosis (1 case), hepatitis B virus-related cirrhosis (2 cases), autoimmune disease-associated portal hypertension (1 case), and thrombophilia-related portal hypertension (1 case). Immediate hemostasis was achieved endoscopically in all cases. Two patients (1 alcohol-related and 1 hepatitis B virus-related cirrhosis) exhibited persistent decline in hemoglobin levels post-procedure and received sequential interventional therapy before discharge. The remaining 3 patients recovered uneventfully. Duodenal variceal bleeding, though rare and life-threatening, can be effectively managed through multidisciplinary collaboration. Endoscopic hemostasis should be prioritized when technically feasible.

Objective This study aims to summarize the situation,development experiences,and existing problems in the development of Hospital S,and provide relevant suggestions as a reference for the high-quality development path of public hospitals.Methods Thirteen managers of Hospital S(including hospital leaders,functional departments,and clinical depart-ment heads)and eight experts in the field of hospital management were selected as research subjects.The phenomenological re-search method of qualitative research was used,and semi-structured interviews were conducted to collect relevant data.The Co-laizzi phenomenological data analysis method was used to analyze the interview data.Results Through the analysis of the inter-view data,four themes related to high-quality development were identified:medical care,scientific research and teaching,tal-ents,and disciplines.Each theme has specific areas that need priority and focused attention.Under the theme of medical care,there are four sub-themes:medical quality,medical safety,medical technology,and medical services.Scientific research and teaching,as a strategic support for promoting the hospital's sustained high-quality development,includes four sub-themes:re-search innovation,achievement transformation,teaching system,and mentor team.Talents,as the core competitiveness of the hospital,include three sub-themes:top-level design,high-level talents,and training system.The discipline theme includes four sub-themes:development ideas,development opportunities,development directions,and discipline leaders.Conclusion Public hospitals are facing new situations in high-quality development,and accelerating the improvement of medical service capabilities is a direct manifestation of high-quality development.It is necessary to promote key work such as research innovation,teaching management,talent team building,and discipline construction in a coordinated manner to achieve synchronous improvement in quality and efficiency.

Objective:To explore a multimodal perioperative analgesia plan for patients undergoing microvascular decompression surgery for trigeminal neuralgia.Methods:Eighty patients who underwent microvascular decompression surgery for trigeminal neuralgia admitted to the Xiangya Hospital, Central South University from April 2017 to April 2019 were randomly divided into a nerve block group (group A) and a control group (group C) using a random number table method, with 40 patients in each group. The group A underwent surgical block of the lateral occipital and auricular nerves under ultrasound guidance before induction, with 3 ml of 0.5% ropivacaine used at each site. The group C did not undergo nerve block. Both groups received intravenous injections of midazolam, sufentanil, cisatracurium, etomidate, and lidocaine for anesthesia induction, followed by tracheal intubation and maintenance of anesthesia with propofol and remifentanil. After surgery, an analgesic pump was connected. The total amount of intraoperative use of sufentanil and remifentanil in both groups was recorded, as well as the pain Visual Analogue Scale (VAS) and postoperative anesthesia related complications at 2, 6, 24, and 48 hours after surgery.Resultsl:The total amount of sufentanil and remifentanil used during surgery in the group A was less than that in the group C (all P<0.05). The incidence of postoperative nausea and vomiting in the group A patients was lower than that in the group C ( P<0.05), and the nausea and vomiting score was also lower than that in the group C ( P<0.05). There was no statistically significant difference in the incidence of other postoperative complications (all P>0.05). There was a statistically significant difference in VAS scores between the two groups at 6 hours after surgery ( P<0.05). Conclusions:Occipital and auricular nerve blockade can reduce the amount of opioid drugs used during microvascular decompression surgery in patients with trigeminal neuralgia, thereby reducing the incidence of nausea and vomiting. The postoperative analgesic effect is good.

Objective To analyze the etiological characteristics and the variation of pathogens spectrum in hospitalized children with a-cute respiratory tract infection(ARTI)before and after COVID-19 under"the level B of management for class B"of infectious diseases(Level B for Class B)in Shenzhen,in order to provide reference for the clinical diagnosis,treatment and prevention of ARTI.Meth-ods The ARTI cases from January 8,2022 to July 30,2022 were selected as before"Level B for Class B",and the cases from Janu-ary 8,2023 to July 30,2023 were selected as after"Level B for Class B".The pharyngeal swab samples submitted for analyzing 11 common pathogens,such as COVID-19,influenza virus(Ⅳ),respiratory syncytial virus(RSV)and mycoplasma pneumoniae(MP)in the children with ARTI admitted to Shenzhen Children's Hospital.Results SARS-CoV-2 were detected as positive in 347 cases,a-mong which 225 cases were before"Level B for Class B"including 29 cases combined with other pathogens(12.89％,29/225)and human parainfluenza viruses(HPIV)was the most common(31.03％,9/29).After"Level B for Class B",SARS-CoV-2 were detec-ted as positive in 122 cases,including 28 cases combined with other pathogens(22.95％,28/122),and RSV was the most common(28.57％,8/28).There was a statistical difference between the positive rate of SARS-CoV-2 combined with other pathogens before and after"Level B for Class B"(X2=5.834,P=0.016).After"Level B for Class B",the total pathogen detection rate(positive for at least one pathogen)was 60.82％(2 864/4 709)in the spring(January 8,2023 to April 30,2023),and influenza virus A(IVA)(22.64％,1 066/4 709),rhinovirus(HRV)(19.86％,935/4 709)and RSV(13.29％,626/4 709)were the main pathogens,and there were 301 cases(6.39％,301/4 709)of mixed infections.In the summer(May 1,2023 to July 30,2023),the total detection rate of pathogens was 70.26％(4 012/5 710),among which RSV(21.63％,1 235/5 710),MP(13.91％,794/5 710),HPIV(10.05％,574/5 710)were the main pathogens,and there were 710 cases(12.43％,710/5 710)of mixed infections,all of which were significantly higher than the same period before"Level B for Class B".The difference was statistically significant(P＜0.05).Conclusion After"Level B for Class B"for COVID-19,the detection rate of 11 common pathogens increased significantly and the pathogen spectrum of ARTI changed significantly.

Objective:To evaluate the clinical efficacy of endoscopy for early cancer of duodenal papilla.Methods:A retrospective analysis was performed on data collected from 23 consecutive patients with early cancer of duodenal papilla, who underwent endoscopic treatment from January 2015 to January 2021 in Beijing Friendship Hospital. Baseline data, endoscopic and pathological data, occurrence and outcome of complications were studied.Results:Twenty-three patients successfully received endoscopic treatment. The maximal diameter of lesions evaluated under endoscopy was 1.90±0.83 cm. Among the 23 cases, 20 underwent endoscopic mucosal resection and 3 underwent endoscopic piecemeal mucosal resection. Delayed bleeding occurred in 5 cases (21.7%), 3 patients (13.0%) developed postoperative hyperamylasemia, 6 patients (26.1%) developed mild acute pancreatitis, and 1 patient (4.3%) had pancreatic duct stent displacement after the operation, which improved after medical or endoscopic treatment. No perforation occurred during the perioperative period. In terms of final pathology, the en bloc resection rate was 82.6% (19/23), and the complete resection rate was 78.3% (18/23). Preoperative endoscopic ultrasonography showed that 19 lesions were confined to the mucosal layer, which were all demonstrated by postoperative pathology. Four other cases were suspected to be involved in the submucosa or the end of the pancreaticobiliary duct under endoscopic ultrasonography, two of which were confined to the mucosal layer, and the other 2 cases involved the submucosal layer, so additional surgery was performed. A total of 18 patients were followed up, among whom 14 achieved complete resection of postoperative pathology, and 2 patients (14.3%, 2/14) were found to have recurrence at 12 and 51 months respectively after the treatment and did not relapse after surgical treatment and endoscopic treatment respectively. Among 4 other patients of follow-up whose pathology did not achieve complete resection, 1 had no recurrence, and the other 3 received additional surgical treatment without recurrence.Conclusion:Endoscopic treatment for early cancer of duodenal papilla is safe and effective. It is necessary to improve preoperative evaluation, stay alert to perioperative complications, and pay attention to regular postoperative endoscopic follow-up.

Objective:To evaluate the clinical efficacy of endoscopic treatment for early nonampullary duodenal cancer.Methods:Data of patients with early nonampullary duodenal cancer, who underwent endoscopic treatment from January 2015 to January 2021 at Beijing Friendship Hospital were retrospectively analyzed. Baseline data, endoscopic treatment methods, wound closure, pathology, the occurrence and outcome of complications of patients were studied.Results:A total of 47 patients who successfully went through endoscopic treatment were enrolled. Seventeen cases received endoscopic mucosal resection (EMR), 5 cases received endoscopic submucosal dissection (ESD), and 7 cases received ESD+EMR (hybrid ESD). Six cases were converted to hybrid ESD due to difficulty in ESD. Four cases received full-thickness resection with over-the-scope clip system (OTSC), and 8 cases received endoscopic piecemeal mucosal resection (EPMR). Among the 47 cases of early cancer, the en bloc resection rate was 83.0% (39/47), and the complete resection rate was 85.1% (40/47). Four patients (8.5%) had perforation which occurred at the duodenal descending part during the perioperative period, among whom, 2 patients (4.3%) recovered after endoscopic treatment, 2 others (4.3%) recovered after surgical intervention. There were no complications such as postoperative bleeding or infection during the perioperative period.Conclusion:Endoscopic treatment for early nonampullary duodenal cancer is safe and effective. A specific treatment plan can be selected according to the location, size and specific conditions of the lesion. For the operation of the descending part, it is necessary to be more vigilant to against the occurrence of perforation complications.

The aim of this study was to investigate the preventive effect of pancreatic duct stent on acute pancreatitis after endoscopic retrograde cholangiopancreatography. A retrospective analysis of the case data of patients who first underwent endoscopic retrograde cholangiopancreatography for choledocholithiasis in the Beijing Friendship Hospital from January 2015 to December 2019 for 5 years. According to whether the pancreatic duct stent was indwelled during the operation, they were divided into pancreatic duct stent group (147 cases) and non-indwelling pancreatic duct stent group (192 cases). The incidence of acute pancreatitis after endoscopic retrograde cholangiopancreatography was compared between the two groups according to COTTON criteria. Independent sample t test, Pearson Chi-square test (χ 2) and Fisher′s exact test were used to compare groups′ differences. There were 2 cases of acute pancreatitis in the pancreatic duct stent group, all of which improved after 48 hours. There were 22 cases of acute pancreatitis in the non-indwelling pancreatic duct stent group, of which 20 cases improved within 48 hours, and the other 2 cases had severe pancreatitis, which improved and discharged after 30 days of treatment. There was significant difference in the incidence of acute pancreatitis between the pancreatic duct stenting group (1.4%) and the group without placement of pancreatic duct stents (11.5%) (χ2=12.905, P<0.001). In conclusion, Pancreatic duct stent may be an effective method to prevent PEP.
