ABSTRACT
Objective:To investigate the surgical efficacy and prognosis influencing factors of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment.Methods:The retrospective cohort study was conducted. The clinicopathological data of 91 patients with hilar cholangiocarcinoma who underwent surgery in Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from April 2004 to April 2021 were collected. There were 59 males and 32 females, aged (61±10)years. Patients who were admitted from April 2004 to March 2014 underwent traditional surgical diagnosis and treatment, and patients who were admitted from April 2014 to April 2021 underwent multidisciplinary diagnosis and treatment. Observation indica-tors: (1) surgical situations; (2) postoperative situations; (3) postoperative pathological examina-tions; (4) postoperative prognosis analysis; (5) influencing factors of postoperative prognosis. Follow-up was conducted using telephone interview and outpatient examination. Patients were followed up once every 6 months after surgery to detect survival. The follow-up was up to April 2023. Measure-ment data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Comparison of ordinal data was conducted using the rank sum test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test or Fisher exact probability. The Kaplan-Meier method was used to draw survival curve and calculate survival rate. The Log-Rank test was used for survival analysis. Univariate and multivariate analyses were conducted using the COX proportional hazard model. Results:(1) Surgical situations. Of the 91 patients, there were 65 cases receiving hemi- or expanded hemi-hepatectomy, 13 cases receiving tri-hepatectomy, 9 cases receiving partial hepatectomy, 4 cases receiving extrahepatic bile duct resection. There were 24 cases receiving combined vein resection and reconstruction, 8 cases receiving combined pancreaticoduodenectomy, 6 cases receiving com-bined hepatic artery resection and reconstruction, including 24 cases receiving extended radical surgery (tri-hepatectomy, hepatic artery resection and reconstruction, hepatopancreaticoduodenec-tomy). The operation time, volume of intraoperative blood loss and intraoperative blood transfusion rate of 91 patients was (590±124)minutes, 800(range, 500?1 200)mL and 75.8%(69/91), respectively. Of the 91 patients, cases receiving extended radical surgery, the volume of intraoperative blood loss were 4, 650(range, 300?1 000)mL in the 31 patients who were admitted from April 2004 to March 2014, versus 20, 875 (range, 500?1 375)mL in the 60 patients who were admitted from April 2014 to April 2021, showing significant differences between them ( χ2=4.39, Z=0.31, P<0.05). (2) Post-operative situations. The postoperative duration of hospital stay and cases with postoperative infectious complications were (27±17)days and 50 in the 91 patients. Cases with abdominal infection, cases with infection of incision, cases with bacteremia and cases with pulmonary infection were 43, 7, 5, 8 in the 91 patients. One patient might have multiple infectious complications. Cases with bile leakage, cases with delayed gastric emptying, cases with chylous leakage, cases with liver failure, cases with pancreatic fistula, cases with intraperitoneal hemorrhage, cases with reoperation, cases dead during the postoperative 90 days were 30, 9, 9, 6, 5, 3, 6, 3 in the 91 patients. Cases with abdominal infection was 10 in the 31 patients who were admitted from April 2004 to March 2014, versus 33 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=4.24, P<0.05). Cases dead during the postoperative 90 days was 3 in the 31 patients who were admitted from April 2004 to March 2014, versus 0 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( P<0.05). (3) Post-operative pathological examinations. Of the 91 patients, cases with Bismuth type as type Ⅰ?Ⅱ, type Ⅲ, type Ⅳ, cases with T staging as Tis stage, T1 stage, T2a?2b stage, T3 stage, T4 stage, cases with N staging as N0 stage, N1 stage, N2 stage, cases with M staging as M0 stage, M1 stage, cases with TNM staging as 0 stage, Ⅰ stage, Ⅱ stage, Ⅲ stage, ⅣA stage, ⅣB stage, cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 46, 30, 1, 9, 25, 30, 26, 49, 36, 6, 85, 6, 1, 7, 13, 58, 6, 6, 63, 28. Cases with R 0 radical resection, cases with R 1 or R 2 resection were 15, 16 in the 31 patients who were admitted from April 2004 to March 2014, versus 48, 12 in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=9.59, P<0.05). (4) Postoperative prognosis analysis. Of the 91 patients, 3 cases who died within 90 days after surgery were excluded, and the 5-year overall survival rate and median overall survival time of the rest of 88 cases were 44.7% and 55 months. The 5-year overall survival rate was 33.5% in the 28 patients who were admitted from April 2004 to March 2014, versus 50.4% in the 60 patients who were admitted from April 2014 to April 2021, showing a significant difference between them ( χ2=5.31, P<0.05). Results of further analysis showed that the corresponding 5-year overall survival rate of cases without lymph node metastasis was 43.8% in the 16 patients who were admitted from April 2004 to March 2014, versus 61.6% in the 31 patients who were admitted from April 2014 to April 2021. There was a significant difference in the 5-year overall survival rate between these patients without lymph node metastasis ( χ2=3.98, P<0.05). The corresponding 5-year overall survival rate of cases with lymph node metastasis was 18.5% in the 12 patients who were admitted from April 2004 to March 2014, versus 37.7% in the 29 patients who were admitted from April 2014 to April 2021. There was no significant difference in the 5-year overall survival rate between these patients with lymph node metastasis ( χ2=2.25, P>0.05). (5) Influencing factors of postoperative prognosis. Results of multivariate analysis showed that poorly differentiated tumor and R 1 or R 2 resection were inde-pendent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma ( hazard ratio=2.62, 2.71, 95% confidence interval as 1.30?5.29, 1.30?5.69, P<0.05). Conclusions:Compared with traditional surgical diagnosis and treatment, treatment of hilar cholangiocarcinoma based on multidisciplinary diagnosis and treatment can expand surgical indications, reduce proportion of dead patients within 90 days after surgery, improve proportation of radical resection and long-term survival rate. Poorly differentiated tumor and R 1 or R 2 resection are independent risk factors influencing prognosis after surgical treatment of hilar cholangiocarcinoma.
ABSTRACT
Objective:To evaluate the application value of small IT knife pre-cut in assistance to duodenal papillary cannulation compared with conventional guidewire cannulation.Methods:A retrospective analysis was performed on the data of 90 patients with choledocholithiasis including 52 patients with small IT knife pre-cut assisted intubation (small IT knife group) and 38 patients with conventional guidewire intubation (conventional group) in endoscopic retrograde cholangiopancreatography (ERCP) from May 2016 to July 2019 in the digestive endoscopy center of Nanjing Drum Tower Hospital. The basic data, curative effect and complications of the two groups were collected and compared.Results:There was statistically significant difference in gender composition between the small IT knife group and the conventional group ( χ2=5.679, P=0.017), but no significant difference in other baseline data between the two groups (all P>0.05). The median intubation time of the small IT knife group was significantly shorter than that of the conventional group (141.5 s VS 270.0 s, Z=1 268.0, P=0.022). There were no significant differences in the success rate of intubation [98.1% (51/52) VS 94.7% (36/38), χ2=0.760, P=0.571], the incidence of intraoperative bleeding [15.4% (8/52) VS 7.9% (3/38), χ2=1.148, P=0.345], postoperative pancreatitis [5.8% (3/52) VS 7.9% (3/38), χ2=0.159, P=0.694], and postoperative cholangitis [1.9% (1/52) VS 5.3% (2/38), χ2=0.760, P=0.571] between the two groups. No perforation occurred in the two groups. After stratifying according to the operator′s proficiency, the median intubation time was significantly different between the small IT knife expert group and the conventional expert group (116.0 s VS 258.0 s, Z=276.0, P=0.038), while there was no significant difference in the intubation time among other groups (all P>0.05). Conclusion:The small IT knife is safe and effective to pre-cut and assist intubation in ERCP, and it may shorten the intubation time.
ABSTRACT
Objective:To investigate the application of accurate endoscopic retrograde cholangiopancreatography (ERCP)drainage guided by IQQA ?-Liver CT(an image interpretation and analysis system)to preoperative jaundice reduction for hilar cholangiocarcinoma. Methods:Data of 12 patients with hilar cholangiocarcinoma who planned to receive surgical treatment in the hepatobiliary surgery department of Nanjing Drum Tower Hospital, the Affiliated Hospital of Nanjing University Medical School from May 2017 to December 2018 were reviewed. All patients were treated with ERCP drainage before surgery. The procedure success rate, postoperative drainage volume and postoperative complications of the patients were analyzed.Results:ERCP was successful in all patients, and the median daily volume of endoscopic nasobiliary drainage was 675 mL(400-1 500 mL). Only 1 patient developed postoperative cholangitis, and another patient developed postoperative mild pancreatitis. The mean serum total bilirubin was 173.3±62.8 μmol/L in the patients before ERCP, which decreased to 35.6±13.9 μmol/L before surgery.Conclusion:Accurate ERCP drainage can effectively reduce the serum bilirubin level in patients with hilar cholangiocarcinoma and reduce the incidence of cholangitis after the procedure, creating favorable conditions for subsequent surgical operations.
ABSTRACT
Objective:To evaluate the safety and efficacy of indwelling cutting with guidewire in treatment of difficult pancreatic duct stricture.Methods:A retrospective study was performed on the data of patients with chronic pancreatitis, who failed to implant pancreatic duct stent by endoscopic retrograde cholangiopancreatography (ERCP) and whose narrow pancreatic duct only allowed the guidewire to pass through, in Nanjing Drum Tower Hospital from November 2017 to April 2019. The dilatation effect of guidewire indwelling on difficult pancreatic duct stenosis was studied. The duration of guidewire indwelling, the success rate of stent re-implantation, the level of postoperative amylase, recent complications, and follow-up results were analyzed.Results:A total of five patients received indwelling guidewire after failure of dilation of pancreatic duct stenosis during ERCP. After 2.4 days of mean indwelling time, all patients received re-ERCP. The narrow pancreatic duct was successfully expanded and the stent was placed. In terms of complications, only one patient suffered from acute pancreatitis after the first ERCP, and was improved after medical treatment.Conclusion:Guidewire indwelling is a new simple, safe, and effective method for dilatation of pancreatic duct stenosis, and has important clinical value in the management of difficult intubation of pancreatic duct in chronic pancreatitis.

ABSTRACT
Intrahepatic cholangiocarcinoma (ICC) is the second most common primary liver cancer with a very poor prognosis.In order to guide better clinical management of ICC patients,the American Joint Committee on Cancer (AJCC) cancer staging manual (7th edition) have established a unique TNM staging scheme for separating ICC from hepatocellular carcinoma (HCC) for the first time,and reflected a difference between risk factor of ICC and HCC.This TNM staging system for ICC has been most recently updated by the AJCC cancer staging manual (8th edition),in which T staging has been redefined without gross features,and lymph node metastasis (N1) in N staging has been grouped as stage Ⅲ B,but not stage Ⅳ as required by the 7th edition of AJCC cancer staging manual.In addition,region lymphatic and distant metastases have been clearly redefined by the AJCC cancer staging manual (8th edition) that also requires recovering at least 6 lymph nodes for the N staging scheme.The apparent advantages of the AJCC cancer staging manual (8th edition) for ICC pathologic staging may better stratify the prognosis of ICC patients and provide an improved guidance in clinical practice.
ABSTRACT
Objective To assess the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) for children with pancreaticobiliary diseases.

ABSTRACT
Objective To explore the effects of different treatments on prognosis of patients with Gynura segetum caused hepatic vein occlusion disease (HVOD).Methods From July 2008 to January 2016,85 patients with Gynura segetum caused HVOD were enrolled and received treatment of liver function protection and microcirculation improvement.According to different treatment options,patients were divided into non-anticoagulation group,nowanticoagulation transfered to transjugular intrahepatic portosystem stent-shunt (TIPS) group,anticoagulation group,anticoagulation transfered to TIPS group and anticoagulation-TIPS step-by-step treatment group.The efficacy of each group was observed.Chi square test was performed for statistical analysis.Results Among 22 patients who received nonanticoagulation treatment,six (27.3％) patients were cured and 14 (63.6％) patients died during the treatment period;besides two (9.1 ％) patients received TIPS because of ineffective treatment and achieved longterm survival.Among 63 patients treated with combination of low-molecular-weight heparin and warfarin,six (9.5％) patients died and 36(57.1％) patients were cured.The cure rate was higher than that of nonanticoagulation group (x2 =5.820,P=0.016).Other 21 patients received TIPS treatment,achieved longterm survival except one patient died from surgical complications.The cure rate of anticoagulation-TIPS step treatment group was 88.9 ％ (56/63) which was higher than that of non-anticoagulation group,and the difference was statistically significant (x2 =31.350,P＜0.01).Conclusions Compared to conventional liver function protection treatment and symptomatic treatment,anticoagulation therapy significantly increases the cure rate of patients with Gynura segetum caused HVOD.Anticoagulation-TIPS step-by-step treatment further improves the cure rate.
ABSTRACT
Objective To explore the correlation between wedged hepatic vein pressure (WHVP) and directly measured portal vein pressure (PVP) and further analyze the correlation between hepatic venous pressure gradient (HVPG) and portal pressure gradient (PPG).Methods From December 2012 to April 2014,the related data including WHVP,free hepatic venous pressure (FHVP),inferior vena cava pressure (IVCP) and PVP of patients who received transjugular interahepatic portosystem stentshunt (TIPS) treatment were collected,and HVPG and PPG were calculated.The correlations between WHVP and PVP,between FHVP and IVCP,between HVPG and PPG were analyzed.Pearson's correlation analysis were performed for correlation analysis.Results Twenty two patients matched the criteria were enrolled during the December 2012 to April 2014.The mean pressures of PVP and WHVP were (28.07±4.43) mmHg (1 mmHg=0.133 kPa) and (26.22±5.91) mmHg,respectively.PVPand WHVP were positively correlated,the correlation coefficient of them was 0.431 (P=0.045) and slope was0.323.The mean pressures of FHVP and IVCP were (7.31±3.37) mmHg and (6.82±4.01) mmHg,respectively.FHVP and IVCP were positively correlated,the correlation coefficient of them was 0.845 (P＜0.01) and slope was 0.711.The mean pressures of PPG and HVPG was (21.02±3.76) mmHg and (18.90±4.86) mmHg,respectively.There was no correlation between PPG and HVPG,the correlation coefficient of them was 0.014 (P=0.951).Conclusions There is a good correlation between PVP and WHVP,and so is the correlation between FHVP and IVCP.However,there is no good correlation between HVPG and PPG in this study because of the effects of many factors.
ABSTRACT
Objective To study the risk factors for pathological upgrading after diagnosis of esophageal low?grade intra?epithelial neoplasia with ESD preoperative biopsy. Methods The endoscopic and pathological data of 85 lesions with ESD preoperative biopsy were analyzed, and grouped based on pathological upgrading after ESD. The risk factors for pathological upgrading after ESD was studied through single and multiple factor analysis. Results Pathological upgrading occurred in 45(52?94%) lesions after ESD, among whom 38 lesions developed up to high?grade intra?epithelial neoplasia and 7 lesions developed to esophageal early cancer. NBI?ME was performed on 37 patients and the accuracy of detecting the pathological invasion was 83?8%(31/37).Multi?factor analysis showed that reddish surface(OR=9?478, 95%CI:2?775?32?368, P = 0?000 3 ) and nodular lesion ( OR = 15?628, 95%CI:1?475?165?617, P =0?022 5) were independent factors for pathological upgrading after ESD. Conclusion Pathological upgrading of low?grade intra?epithelial neoplasia was common, especially esophageal mucosa with red surface and nodular lesion.Biopsy combined with NBI?ME is of significant importance to improve diagnostic accuracy.

ABSTRACT
<p><b>OBJECTIVE</b>To assess the safety and clinical efficacy of transjugular intrahepatic portosystemic shunt (TIPS) with various stents for treating patients with cirrhosis and esophageal gastric varices bleeding.</p><p><b>METHODS</b>One hundred and five patients were stratified according to stent type: bare stent group, covered stent-grafts group, combined stents group. Rates of success, shunt insufficiency, rebleeding, patient survival, and major complications were observed. The shunt insufficiency rate, rebleeding rate, and survival rate were calculated by the life tables method, the Kaplan-Meier analytical curve, and the log-rank test; a p-value less than 0.05 was considered statistically significant.</p><p><b>RESULTS</b>The overall success rate of all TIPS for treating the esophageal gastric varices bleeding was 100%. The overall shunt insufficiency rates at 6-, 12-and 24-months post-TIPS were 8%, 9% and 16%, rebleeding rates were 2%, 6% and 17%, and survival rates were 100%, 97% and 94%. The shunt insufficiency rate was 26% in the bare stent group, 14% in the covered stent-grafis group, and 5% in the combined stents group (x2=1.00, P=0.61). The rebleeding rate was 33% in the bare stent group, 7% in the covered stent-grafts group, and 3%in the combined stents group (x2=1.69, P=0.43). The survival rate was 92% in the bare stent group, 93% in the covered stent-grafts group, and 100% in the combined stents group (x2=1.91, P=0.39). The shunt insufficiency rates were higher in patients with splenectomy than in those without splenectomy (30% vs.14%; x2=4.15, P=0.04). The intraperitoneal hemorrhage rates in the covered stent-grafis group and the combined stents group were significantly lower than that in the bare stent group (0% vs 0% vs 13%; x2=8.88, P=0.01).</p><p><b>CONCLUSIONS</b>TIPS with an 8 mm stent effectively treated and prevented esophageal gastric varices bleeding in patients with cirrhosis. Intraperitoneal hemorrhaging caused by TIPS was significantly decreased in the covered stent-grafts group and combined stents group,which represented an improvement in safety of this treatment. However, the influence of covered stent-grafis and combined stents towards the clinical efficacy of TIPS needs further study.</p>

ABSTRACT
Objective To investigate the risk factors of post-ERCP pancreatitis( PEP). Methods Data of 4,234 patients who underwent ERCP in Nanjing Drum Tower Hospital were retrospectively analysed. Information of patients and operations,including age,gender,operation history,major disease history,labora-tory examination before operation,abdominal ultrasound,CT,MRCP,detailed ERCP operation process,com-plications and treatment were carefully recorded. Then Chi-square test was used for univariate analysis,and stepwise multivariate Logistic regression for variate analysis. Linear correlations between risk factors were de-tected. Results There were totally 226 PEPs,with 5. 3% incidence rate. Univariate analysis showed that the female(χ2 =9. 715,P=0. 002),young( <60 years)(χ2 =6. 108,P=0. 013),chronic pancreatitis(χ2 =14. 703,P=0. 001),initial ERCP(χ2 =14. 899,P=0. 000),hypertension(χ2 =4. 489,P=0. 034),nor-mal bilirubin levels before operation(χ2 =19. 159,P =0. 000 ),difficult cannulation(χ2 =45. 824,P =0. 000),pancreatic guide wire(χ2 =30. 223,P=0. 000),papillary pre cut(χ2 =45. 928,P=0. 000),pan-creatography(χ2 =20. 170,P=0. 000)may be risk factors for PEP. Non conditional Logistic regression analy-sis showed that female(OR=1. 449,P=0. 011),initial ERCP(OR=1. 745,P=0. 003),normal bilirubin levels before operation(OR=1. 917,P=0. 000),difficult cannulation(OR=3. 317,P=0. 000)and pancre-atography(OR=1. 823,P=0. 004)were independent risk factors for PEP. Linear correlation analysis sugges-ted that pancreatic duct guide wire and papillary precut were related to the difficult cannulation,and the corre-lation coefficients were -0. 788 and -0. 699. Conclusion Female,young(<60 years),chronic pancreati-tis,initial ERCP,hypertension,normal bilirubin levels,difficult cannulation,pancreatic duct guide wire,pa-pillary precut,pancreatography may induce PEP. Female,normal bilirubin levels before operation,initial ER-CP,difficult cannulation and pancreatography are independent risk factors for PEP,while pancreatic duct guide wire,papillary precut are not,as they were linear correlated to difficult cannulation.
ABSTRACT
Objective To investigate the efficacy of pancreatic duct stent in preventing post-ERCP pancreatitis (PEP) of difficult bile duct cannulation.Methods A total of 120 patients who underwent difficult bile duct cannulation during routine ERCP were randomized to receive pancreatic duct stent placement (S group) or not (NS group),and the incidence of PEP,hyperamylasemia and scores of abdominal pain were analyzed.Results There were 15 cases of hyperamylasemia and 5 cases of PEP occurred in S group,but no severe PEP was observed.The score of abdominal pain was (3.82 ± 1.48) in S group.There were 18cases of hyperamylasemia and 14 cases of PEP occurred,including 2 severe PEP in NS group.The score of abdominal pain was (7.48 ± 1.93) in NS group.There was no significant difference in the incidence of hyperamylasemia between the two groups (P ＞ 0.05).The incidence of PEP,severe PEP and the scores of abdominal pain were lower in the S group (P ＜ 0.05).Conclusion Placement of pancreatic duct stent can reduce the PEP rate of difficult bile duct cannulation and relieve the abdominal pain.
ABSTRACT
Objective To evaluate the efficacy and safety of endoscopic therapy in the treatment of symptomatic pancreatic divisum (PD).Methods Data of 8 patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) with the diagnosis of pancreas divisum at our institution from June 2006 to June 2013 was retrospectively analyzed.Results The patients were identified as pancreatic divisum with 28 ERCP procedures.All patients received stent placement,7 underwent minor papilla sphincterotomy,6 pancreatic duct stricture dilatation,and 1 stone extraction.Post-endoscopic retrograde cholangiopancreatography pancreatitis occurred in 1 patient,and no other complications occurred.After a follow-up of 2-47 months,1 patient died of pancreatic carcinoma,3 patients removed the stents,3 patients were followed up regularly,and 1 was unavailable for the interview.The episode of chronic pancreatitis and the extent of abdominal pain decreased after the operations.Conclusion Endoscopic therapy is effective and safe for the pancreatic divisum patients.It can reduce the episode of chronic pancreatitis and relieve the chronic abdominal pain in PD patients with low incidence of complication.
ABSTRACT
DNA vaccine plays an important role in the treatment of cancer, infectious disease and self-immune disease. Further enhancement of immune responses to DNA vaccines is one of the hot spots in the vaccine development. Among the research combining the electroporation with DNA vaccination improves plasmid gene expression in vivo and significantly enhances the immune responses. This review gives an overview of the application, effectiveness and prospect of electroporation in improving the efficacy of DNA vaccine.
