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 investigate the serum levels of angiopoietin-like protein-3(ANGPTL3)and nuclear factor of active T cells cytoplasmic 1(NFATc1)in patients with cerebral infarction,and their relationship with the severity and prognosis of the disease.Methods A total of 180 patients with cerebral infarction set as cere-bral infarction group who underwent treatment in our hospital from January 2021 to January 2023 were collected as research subjects.According to the NIHSS score,the patients were divided into mild group(n = 68),moderate group(n = 76),and severe group(n = 36),respectively.According to the mRS Score,they were divided into a good prognosis group(n = 117)and a poor prognosis group(n = 63).Another 180 healthy people were enrolled as the control group.The levels of serum ANGPTL3 and NFATc1 were compared among the groups.Multivariate logistic regression was adopted to analyze the influencing factors of prognosis in the patients with cerebral infarction.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of serum ANGPTL3 and NFATc1 on the prognosis of the patients with cerebral infarction.Results The serum levels of ANGPTL3 and NFATc1 in the cerebral infarction group were significantly higher than those in the control group(P<0.05).The levels of serum ANGPTL3 and NFATc1 were significantly increased in an ascending order across the mild,moder-ate,and severe groups(P<0.05).The volume of cerebral infarction,white blood cell count,ANGPTL3,and NFATc1 levels in the patients with poor prognosis were significantly higher than those in the patients with good prognosis(P<0.05).Regression analysis showed that cerebral infarction volume,white blood cell count,ANG-PTL3,and NFATc1 were the influencing factors of the prognosis of cerebral infarction patients(P<0.05).The levels of ANGPTL3 and NFATc1 together were more effective than they were alone in predicting the prognosis of the patients with cerebral infarction(Z combined detection-ANGPTL3 = 3.345,Z combined detection-NFATc1 = 2.898;P = 0.001,0.004).Conclusion The serum levels of ANGPTL3 and NFATc1 in patients with cerebral infarction are significantly increased,with the increase amplitude depending on the severity of the condition.ANGPTL3 and NFATc1,when combined,are more effective and valuable for predicting the prognosis of cerebral infarction patients.

Objective:To evaluate the diagnostic efficacy of brush cytology and transpapillary biopsy sampling under the guidance of endoscopic retrograde cholangiopancreatography (ERCP) in distinguishing between benign and malignant biliary strictures.Methods:A total of 470 patients with unknown biliary strictures who underwent ERCP at Department of Gastroenterology, Beijing Friendship Hospital from January 2013 to January 2022 were enrolled. Brush cytology was performed before biopsy in a single procedure, and with multiple ERCP brush cytologies or biopsy performed for challenging cases. Clinical data, ERCP procedures, pathological results, and follow-up data were collected. With the final diagnosis as the golden standard, the diagnostic efficacy of brush cytology and biopsy sampling were calculated.Results:The final diagnosis showed 251 cases of malignant and 219 cases of benign biliary strictures. All 470 patients received brush cytology, among whom, 37 patients underwent multiple brush cytologies. Additionally, 114 patients were treated with biopsy sampling. The single brush cytology showed a sensitivity of 49.40% (124/251) and a specificity of 99.09% (217/219) for diagnosing malignant biliary strictures. Multiple brush cytologies showed a sensitivity of 68.42% (13/19) and a specificity of 100.00% (18/18). Biopsy sampling showed a sensitivity of 68.18% (45/66) and a specificity of 97.92% (47/48). Among the 114 patients who underwent both brush cytology and biopsy sampling, the results showed that the diagnostic sensitivity of brush cytology combined with biopsy sampling [77.27% (51/66)] and the sensitivity of single biopsy sampling [68.18% (45/66)] were significantly higher than that of single brush cytology [43.94% (29/66), χ 2=13.99, P<0.001; χ 2=6.92, P=0.009]. Conclusion:Combining brush cytology and biopsy forceps during ERCP enhances diagnostic sensitivity in identifying malignant biliary strictures. Biopsy sampling stands out as more sensitive compared with single brush cytology, emphasizing its role in improving diagnostic capabilities.

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.
