RESUMO
Background:One effective method for detecting stomach cancer is serological screening.Aims:To improve the prognosis and better direct clinical practice,this research compares the usefulness of the new scoring system and the ABC method in the screening of high-risk lesions of gastric cancer.Methods:This study involved the consecutive enrollment of 2 306 individuals(of whom 1 232 were male and 1 074 were female)who had gastroscopy at the Physical Examination Department of Xiamen Humanity Hospital between December 2020 and December 2022 and were above the age of 40.Before endoscopy,the population was classified as low-risk,intermediate-risk,and high-risk based on the serological ABC method and the new scoring system,respectively,and based on the age,gender,serum Helicobacter pylori antibody,PGR,and G-17 test findings of the studied population.An analysis was conducted on the identification of high-risk lesions of stomach cancer using the two distinct approaches,and the usefulness of the two distinct techniques for identifying high-risk lesions associated with stomach cancer was assessed.Results:Based on the serological ABC method of 2 306 patients,there were 1 293 cases in the low-risk group,856 cases in the intermediate-risk group,and 157 cases in the high-risk group.Of the three groups,759 cases(58.7%)had high-risk lesions of gastric cancer,492 cases(57.5%)in the intermediate-risk group,and 82 cases(52.2%)in the high-risk group.There were 1 899 cases in the low-risk category,383 cases in the intermediate-risk group,and 27 cases in the high-risk group,based on the novel scoring system.Among them,1 044 patients had high-risk stomach cancer lesions found.There were 18 instances(75.0%)in the high-risk group and 271 cases(70.8%)in the intermediate-risk group.The identification rate of high-risk lesions of gastric cancer in the new scoring method increases progressively as the group grade rises(χ2=35.482,P<0.001).Conclusions:While both approaches are useful for identifying high-risk gastric cancer lesions,the novel scoring system may be more beneficial for identifying these lesions early on.
RESUMO
Objective To investigate the clinical outcome of pancreatic pseudocyst(PPC)treated with non-surgical methods,and to compare the efficacy and safety between percutaneous drainage and endoscopic drainage in the management of PPC.Methods From February 2010 to July 2017,clinical data of patients with PPC,who received percutaneous drainage or endoscopic drainage,were retrospectively analyzed.The symptom relief rate,short-term and long-term radiologic remission rate,complication rate, recurrence rate and length of hospital stay were compared between patients treated by ultrasound guided percutaneous drainage(percutaneous group),by endoscopic ultrasonography-guided drainage(EUS group)and by endoscopic retrograde pancreatography guided transpapillary drainage(ERP group).Two independent samples t test,one-way analysis of variance,non-parametric test and Fisher′s exact test were performed for statistical analysis.Results A total of 153 patients were treated and the operation was successfully conducted in 148 patients(96.7%),of whom 39 were in percutaneous group,73 in EUS group and 36 in ERP group.The median follow-up time was 26 weeks(two weeks to 358 weeks).The symptom relief rate,long-term radiographic remission rate,complication rate,recurrence rate and retreatment rate of percutaneous group,EUS group and ERP group were 87.2%(34/39),79.5%(58/73),80.6%(29/36);81.5%(22/27),88.6%(39/44),66.7%(16/24);17.9%(7/39),28.8%(21/73),16.7%(6/36);15.0%(3/20),13.8%(8/58),10.0%(2/20);and 10.3%(4/39),8.2%(6/73),2.8%(1/36),respectively.There was no statistically significant difference among three groups (all P> 0.05).The short-term radiographic remission rate of ERP group was significantly lower than those of percutaneous group and EUS group(46.7%,14/30 vs 77.1%,27/35 and 87.7%,64/73),and the differences were statistically significant(χ2 =6.442 and 19.450,both P<0.01).The median hospital stay of percutaneous group was longer than those of EUS group and ERP group(14.0 days vs 9.0 days and 8.0 days),and the differences were statistically significant(Z= -3.687 and -2.630,both P<0.01).Conclusions The efficacies of percutaneous drainage and EUS-guided drainage are both better than ERP,and they are effective and safe methods especially for the patients with complication of pseudocysts and necrosis debris in pseudocysts.However,the hospitalization time of percutaneous drainage is longer. In addition,percutaneous drainage can be an alternative method after failed endoscopic drainage.
RESUMO
Objective@#To investigate the history, risk factors for prognosis of malignant biliary stricture (MBS) patients receiving conservative therapy after endoscopic retrograde cholangiopancreatography(ERCP) and to set up a predictive model for overall survival (OS).@*Methods@#MBS patients who underwent ERCP and conservative therapy in Xijing Hospital and PLA No.451 Hospital from January 2009 to December 2013 were enrolled to the present study. Predictive factors associated with OS were identified in the training cohort by stepwise multivariate Cox regression analysis. A predictive model was then developed and externally validated in the validation cohort.@*Results@#Between January 2009 and December 2013, 152 and 149 patients were eligible to the training and validation cohort respectively. In the training cohort, tumors were mainly originated from bile duct (33.6%), pancreas (23.5%) or ampulla (20.4%). 76.3% (116/152) patients died during the observation period. The median OS for the training population was 5.0 months (3.9-6.2 months). CA19-9≥1 000 U/mL, non-ampulla tumor, metastasis, pre-ERCP total bilirubin≥7 mg/dL and hilar stricture were identified as independent predictive factors of poor OS (all P<0.05). Based on these factors, the COMTH predictive model was developed. The median OS of patients with COMTH>8 in the training and validation cohorts were both 3.0 months, which were significantly shorter than those with COMTH≤8 (10.0 and 6.9 months in the training and validation cohorts respectively, both P<0.001).@*Conclusion@#The prognosis of MBS patients undergoing ERCP is poor. The survival chance of patients with COMTH>8 is even more dismal.
RESUMO
Objective To analyze the risk factors of post-ERCP pancreatitis (PEP) and to evaluate the relationship between cannulation time and PEP.Methods The data of cannulation time in 1 625 patients who underwent ERCP from 2010 to 2012 were retrospectively studied.The risk factors associated with PEP were analyzed by univariate and multivariate Logistic regression analysis.The effect of different cannulation time on PEP was evaluated.Results The incidence of overall PEP was 4.6％ (75/1 625) including 4.1％ (67/1 625)of mild and 0.5％ (8/1 625)of moderate-to-severe.Univariate analysis revealed that diabetes mellitus (P =0.02),choledocholithiasis (P =0.02),malignant biliary stenosis (P =0.007),duodenal stenosis (P =0.029),precut (P＜0.01),cannulation time ≥ 8 min (P＜0.01),blood platelet count ≥ 180× 109/L(P =0.089),alkaline phosphatase ≥ 120 U/L (P =0.083) and total bilirubin ≥ 17.1 μmol/L (P =0.094)were associated with PEP.Multivariate analysis revealed that precut (OR=1.93,95％CI:1.10-3.39,P=0.022),cannulation time ≥8 min (OR =3.50,95％CI:2.00-6.13,P＜0.01) and duodenum stenosis (OR=2.92,95％CI:1.08-7.86,P=0.034) were independent risk factors of PEP.Within 30 min of cannulation,longer cannulation time was accompanied with higher PEP rate.Conclusion The cannulation time is an independent risk factor of PEP.Overall PEP is increased when cannulation time is more than 8 min.
RESUMO
Objective To explore the success rate and failure risk factors of biliary stenting on the patients with type Ⅰor Ⅱ duodenal malignant stricture treated by self-expandable metallic stent (SEMS). Methods A total of 36 patients with unresectable duodenal stricture after endoscopic SEMS placement be-tween February 2010 and February 2014 at Xijing Digestive Disease Hospital were enrolled.These patients underwent ERCP biliary metal stenting subsequently due to the malignant biliary stenosis.The clinical and imaging features of these patients were retrospectively analyzed.Results ERCP biliary stenting was suc-cessfully completed in 66.7% of patients with previous duodenal SEMS treatment.The success rates of pa-tients with type Ⅰ and Ⅱ duodenal stricture were 88.0% and 18.2% respectively(P <0.001).The suc-cess rates of patients with different lengths of duodenal stenosis were 88.9% for <3.5 cm and 44.4% for ≥3.5 cm (P =0.005).Compared with 80 or 90 mm duodenal stent,patients with 60 mm stent had a higher completion rate for ERCP biliary stent (88.0% VS 18.2%,P <0.001).Multivariate logistic regression a-nalysis revealed that length of duodenal stenosis ≥3.5 cm and 80 or 90 mm duodenal stent were independent factors for failure of ERCP in patients with previous SEMS placement.Conclusion For unresectable DMS patients with SEMS placement,subsequently ERCP biliary metal stenting is safe and effective.The length of duodenal malignant stenosis and longer duodenal stent are high-risk factors for the failure of ERCP biliary stenting.

RESUMO
Objective To investigate the role of endoscopic retrograde cholangiopancreatography (ERCP) management in the diagnosis and treatment and illustrate clinical features of non-iatrogenic hemobi lia.Methods A total of 35 patients diagnosed as hemobilia via endoscope from August 2009 to September 2012 were reviewed retrospectively.Patients with iatrogenic causes of hemobilia were excluded in this study.Results The clinical features of hemobilia mainly included jaundice (77.1％),abdominal pain (62.9％),hematemesis (5.7％),melena (2.9％) and hematochezia (2.9％).Quincke triad was found in 4 patients with hemobilia.Hemobilia were caused by hepatobiliary malignancies in 29 patients and benign biliary tract diseases in the other six.Biliary obstruction caused by hemobilia was successfully ameliorated by ERCP in 34 patients.Postoperative pancreatitis ocurred in 1 patient.Conclusion The common noniatrogenic causes of hemobilia were hepatobiliary and pancreatic malignancies.ERCP is recommended as the initial management to confirm the hemobilia and solve biliary obstruction.
RESUMO
Objective To investigate the efficacy and complications of therapeutic ERCP for patients over 80 years. Methods Data of 80 patients aging over 80 years, who tnderwent therapeutic ERCP from August 2007 to August 2009 were retrospectively studied. The etiology, complications and therapeutic effects were evaluated. Results A total of 51 patients (63. 8% ) were accompanied by cardiovascular diseases, and 43 patients were diagnosed as having malignant bile duct stricture (53. 8% ). The overail therapeutic efficacy was 96. 3%. The incidence of post-operative complications was 12. 5% (10/80). Occurrence of complications in patients with malignant tumors ( 18. 6% ) was significantly higher than that in patients with bile duct stones (5.6% ,P ＜0. 05). Incidence of complications in those with cardiopulmonary diseases was similar with that in patients without (11.8% vs. 13.8%,P＞0.05). Conclusion Age more than 80should not be considered as contraindication of ERCP. Therapeutic ERCP is effective in senior patients. Patients with advanced ages shows a relatively high incidence of complication after ERCP, which may not be related to other accompanying diseases.
