ABSTRACT

Objective:To explore the preventive effects of pancreatic duct stent combined with rectal administration of indomethacin suppository for post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP) after difficult bile duct intubation during endoscopic retrograde cholangiopancreatography (ERCP).Methods:From January 2019 to December 2021, patients with biliary and pancreatic diseases undergoing ERCP in Hangzhou Hospital Affiliated to Nanjing Medical University were given 100 mg indomethacin suppository to anal canal 30 minutes before the operation. And those with difficult bile duct intubation during the operation ( n=204) were included in this study. According to the random number table, they were divided into the combination group (implanted with pancreatic duct stent during the operation, n=104) and the indomethacin group (not implanted with stent, n=100). The incidences of hyperamylasemia and PEP were compared between the two groups. Results:The incidences of postoperative hyperamylasemia [21.2% (22/104) VS 34.0% (34/100), χ2=4.22, P=0.040] and PEP [14.4% (15/104) VS 32.0% (32/100), χ2=8.88, P=0.003] in the combination group were significantly lower than those in the indomethacin group. There was no significant difference in the incidence of severe PEP between the two groups [1.0% (1/104) VS 1.0% (1/100), χ2=0.001, P=0.978]. Conclusion:Compared with rectal administration of indomethacin suppository alone, the incidences of hyperamylasemia and PEP after difficult bile duct intubation during ERCP can be further reduced when it is combined with pancreatic duct stent placement.

ABSTRACT

Objective:To compare the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) assisted with colonoscope and enteroscope in patients with history of Roux-en-Y anastomosis.Methods:A retrospective study was performed on the data of 70 patients who underwent ERCP assisted with standard colonoscope or single balloon enteroscope after Roux-en-Y reconstruction in Hangzhou Hospital Affiliated to Nanjing Medical University from January 2017 to December 2020. Patients were divided into the standard colonoscopy group ( n=43) and the single balloon enteroscopy group ( n=27) according to endoscopy. The success rates of insertion, intubation and ERCP, and incidence of complications were compared. Results:A total of 81 ERCP procedures were performed in 70 patients. The insertion success rates of the standard colonoscopy group and the single balloon enteroscopy group were 91.8% (45/49) and 78.1% (25/32), respectively, showing no significant difference ( χ2=2.04, P=0.153). The success rates of primitive papilla intubation in the two groups were 74.1% (20/27) and 1/6, showing significant difference ( P=0.016). The ERCP success rates of the standard colonoscopy group and the single balloon enteroscopy group were 75.5% (37/49) and 59.4% (19/32), showing no significant difference ( χ2=2.36, P=0.124). The post operative complication incidences of the standard colonoscopy group and the single balloon enteroscopy group were 4.1% (2/49) and 9.4% (3/32), showing no significant difference ( χ2=0.25, P=0.620). Conclusion:ERCP assisted with standard colonoscope and single balloon enteroscope is safe and effective in patients after Roux-en-Y anastomosis. Standard colonoscopic ERCP can become an endoscopy solution for patients with biliary tract disease after Roux-en-Y reconstruction.

ABSTRACT

To evaluate the clinical efficacy and safety of Hot AXIOS, a novel luminal metal stent with a cautery system guided by endoscopic ultrasound, for the treatment of infected pancreatic necrosis (IPN), 5 cases of IPN treated with endoscopic ultrasound-guided Hot AXIOS placement in Hangzhou First People's Hospital from December 2021 to January 2022 were retrospectively analyzed. The results showed that all 5 cases successfully completed the treatment, with 8-21 minutes of the operation time. The symptoms of abdominal pain and bloating on the first day after operation were significantly relieved, and the abdominal CT showed that the walled-off necrosis was significantly reduced. After 2-9 times of direct endoscopic necrosectomy, supplemented by antibiotics, patient's temperature and blood inflammatory indexes returned to normal, the cavity was reduced and necrosis was removed. The Hot AXIOS stent was indwelled for 12-40 days and then removed. After 25-113 days of the follow-up, all patients survived without recurrence. Preliminary results suggest that endoscopic ultrasound-guided Hot AXIOS placement is safe and effective for the treatment of IPN.

ABSTRACT

Objective:To evaluate the safety, efficacy and performance of disposable cholangiopancreatoscope in the diagnosis and treatment of bile duct diseases.Methods:A total of 20 subjects were selected and 16 subjects were enrolled in the prospective and exploratory clinical study which were performed in the Digestive Endoscope Center of Hangzhou First People's Hospital Affiliated to Zhejiang University School of Medicine from July 2021 to August 2021. The disposable cholangiopancreatoscope was used to diagnose bile duct diseases in routine endoscopic retrograde cholangiopancreatography. Biopsies were performed in cases where malignancy was considered. The use related indexes and performance indexes of the instruments were analyzed.Results:Among the 16 patients, there were 6 cases of biliary space-occupying lesions, 6 cases of biliary calculi, and 4 cases of benign biliary stricture before operation. The success rate of the disposable insertion was 100.00% (16/16), and the success rate of observation was 100.00% (16/16). Three biliary space-occupying lesions diagnosed as malignant tumor under cholangiopancreatoscope were confirmed by pathology after operation. Diagnosis of other patients was consistent with preoperative diagnose, so no biopsy was conducted. The rate of positive feedback from operators in directional control was 81.25% (13/16), the image failure rate was 18.75% (3/16), and the rate of positive feedback for image clarity was 93.75% (15/16). In terms of clinical performance, the imaging quality of excellence was 93.75% (15/16), the flexible degree of excellence was 81.25% (13/16), and other indexes were all 100.00% excellence. During the period, there were no instrument defects, pancreatitis, perforation, bleeding or other instrument-related adverse events.Conclusion:The effectiveness, safety and performance indexes of domestic disposable cholangiopancreatoscope have reached the standards of clinical application with high pixel, integration, and portability. It's worthy of clinical recommendation.

ABSTRACT

Objective:To evaluate the efficacy and safety of lumen-apposing metal stent (LAMS) for the treatment of pancreatic walled-off necrosis (WON).Methods:A retrospective cohort study was performed on data of 43 consecutive patients with pancreatic WON who underwent endoscopic ultrasound-guided drainage by LAMS or plastic stents (PS) in Hangzhou First People's Hospital from December 2010 to June 2020. According to the type of stent used, the patients were divided into the LAMS group ( n=16) and the PS group ( n=27). The technical success rate, the clinical success rate, the operation time, the session of endoscopic necrosectomy, the stent insertion time and adverse events were compared between the two groups. Results:All 43 patients were successfully stented, indicating a technical success rate of 100% in both groups. For the LAMS group, the clinical success rate, the operation time, the session of endoscopic necrosectomy, the stent insertion time and overall incidence of adverse events were 75.0% (12/16), 26.0 (19.1, 39.8) min, 0.5 (0, 2.0) times, (41.3±28.4) days, and 43.7% (7/16), respectively, whereas these indices of the PS group were 37.0% (10/27) ( χ2=5.795, P=0.016), 31.0 (26.0, 48.0) min ( Z=1.221, P=0.222), 0 (0, 0) times ( Z=2.245, P=0.025), (176.1±99.1) days ( t=5.187, P<0.001) and 14.8% (4/27) ( χ2=8.893, P=0.064), respectively. Conclusion:LAMS placement is safe and effective for the treatment of pancreatic WON with a higher clinical success rate compared with PS. However, it requires more endoscopic intervention.

ABSTRACT

Objective:To study the influencing factors of postoperative complications in patients with malignant biliary obstruction treated by endoscopic radiofrequency ablation(RFA).Methods:Data of patients with malignant biliary obstruction who underwent endoscopic RFA at the Department of Gastroenterology, Affiliated Hangzhou First People's Hospital, Zhejiang University School of Medicine from January 2010 to June 2021 were retrospectively analyzed. There were 62 males and 48 females, with age (74.1±11.1) years. Based on occurrence of postoperative complications, these patients were divided into the complication group ( n=18) and the control group ( n=92). Univariate and multivariate logistic regression analysis were used to analysis the influencing factors of complications. Results:RFA was successfully performed in 110 patients with malignant biliary obstruction, and the technical success rate was 100.0% (110/110). Postoperative complications occurred in 18 patients (16.4%), including 12 patients with of biliary tract infection (8 patients with acute cholangitis, 4 patients with acute cholecystitis) and 6 patients with acute pancreatitis. All these patients responded well to treatment. The proportion of patients who developed complications having associated diabetes, bile duct stenosis length >2.5 cm, fractional RFA for bile duct stenosis, and single stent drainage were significantly higher than those in the control group (all P<0.05). Multivariate logistic regression analysis showed that the risk of complications after endoscopic RFA was significantly increased in patients with diabetes ( OR=6.967, 95% CI: 1.256-38.658) and fractional RFA of bile duct stenosis ( OR=8.297, 95% CI: 1.526-45.122), while the risk of complications after multiple stents drainage ( OR=0.037, 95% CI: 0.008-0.169) was significantly decreased (all P<0.05). Conclusion:Diabetes and fractional RFA of bile duct stenosis were risk factors for complications after endoscopic RFA of malignant biliary obstruction. Multiple stents drainage was a protective factor. Better clinical attention should be paid to the patients with high risk factors.

ABSTRACT

To evaluate the value of endoscopic retrograde cholangiopancreatography(ERCP)and SpyGlass in the diagnosis of intraductal papillary mucinous neoplasm of the bile duct (IPMN-B). Data of patients who underwent ERCP and SpyGlass in Hangzhou First People′s Hospital from January 2016 to December 2019 were analyzed. ERCP and SpyGlass features, complications, clinicopathologic characteristics and prognosis were retrospectively analyzed.A total of 9 patients (5 benign lesions and 4 malignant lesions) were included.ERCP was successfully performed in 9 cases, while SpyGlass was technically successful in 8 cases. Endoscopy showed mucus outflow from the papilla in 5 cases, and the mucus was removed by the balloon of ERCP in 8 cases.ERCP showed bile duct diffuse dilatation and filling defects in all patients. SpyGlass found the mucus in the bile duct in all patients. SpyGlass showed lesion mucosa were fish-egg like without vascular images (Ⅱtype, 3 cases), fish-egg like with vascular images (Ⅲ type, 1 case), villous (Ⅳtype, 4 cases). SpyGlass defined extent of the lesion in 8 cases. SpyGlass found that the lesion involved the intra and extrahepatic bile ducts in one case. Therefore, liver transplantation was recommended to avoid surgical exploration. One type Ⅲ lesion underwent a direct biopsy. The pathology showed moderate dysplasia, which was consistent with the postoperative pathology. No complication occurred. ERCP combined with SpyGlass could clarify the scope of IPMN-B and provide basis for surgical options, which is safe and effective in IPMN-B diagnosis.

ABSTRACT

Objective:To evaluate the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) for pancreas divisum(PD)with chronic pancreatitis (CP) in adults.Methods:Data of patients older than 18 years old diagnosed as having PD with CP in Hangzhou First People′s Hospital from January 2008 to January 2020 were retrospectively analyzed, i. e.the general information, ERCP procedures and follow-up data of the patients. The number of acute pancreatitis attacks, visual analogue scale (VAS) of abdominal pain, and the diameter of pancreatic duct before and after ERCP were compared.Results:A total of 61 patients diagnosed as having PD with CP underwent 301 ERCP procedures with the median number of 4(3.0-6.5). The median number of pancreatic stent replacement was 3 (2-6). The success rate of the first minor papilla cannulation was 90.2% (55/61), and the total success rate of minor papilla cannulation was 98.0% (295/301). The efficacy rate of the first ERCP was 82.0% (50/61). ERCP-related complication rate was 2.7% (8/301). The median follow-up time was 54 months (31.0-97.5 months). The median number of acute pancreatitis attacks decreased from 2.40 to 0 ( Z=-6.726, P<0.001) compared with that before ERCP. The median VAS decreased from 7 to 2 ( Z=-6.621, P<0.001). The median pancreatic duct diameter decreased from 5.0 mm to 4.0 mm ( Z=-2.330, P=0.020). However, the mean weight increased from 56.04±10.75 kg to 58.62±10.79 kg ( t=-5.285, P<0.001)one year after the procedure. Conclusion:ERCP is safe and effective in the diagnosis and treatment of PD with CP in adults.

ABSTRACT

Objective:To investigate the risk factors of duodenal papilla hemorrhage after endoscopic papillary balloon dilatation (EPBD) for choledocholithiasis.Methods:Clinical data of 411 cases of choledocholithiasis treated by EPBD in Hangzhou First People′s Hospital from January 2016 to December 2019 were analyzed retrospectively. Based on the development of hemorrhage after EPBD, patients were divided into the hemorrhage group and the non-hemorrhage group. The risk factors of hemorrhage after EPBD were analyzed by single and Logistic regression.Results:Among 411 patients who received EPBD, 29 patients had EPBD-related duodenal papilla hemorrhage and the overall incidence was 7.1%.Univariate analysis showed that there were significant differences between the hemorrhage group and the non-hemorrhage group in diameter≥1.2 cm of balloon dilation ( P=0.001), endoscopic sphincterotomy (EST) ( P=0.002)and the incision length of EST ( P<0.001). Logistic regression analysis showed that the incision length of EST ( OR=69.771, 95% CI: 7.544-645.296, P<0.001) was the independent risk factor for duodenal papilla hemorrhage after EPBD. Diameter≥1.2 cm of balloon dilation( OR=0.192, 95% CI: 0.071-0.524, P=0.001) was a protective factor. Conclusion:The incision length of EST is an independent risk factor of duodenal papilla hemorrhage after EPBD. Endoscopic papillary large balloon dilation is a protective factor for postoperative hemorrhage, which can reduce the incidence of bleeding.

Objective:To evaluate the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) for diagnosis and treatment of pancreas divisum (PD) combined with chronic pancreatitis (CP) in children.Methods:Data of patients under 18 years old diagnosed as having PD with CP in Hangzhou First People′s Hospital from January 2010 to January 2020 were retrospectively analyzed. The general information, endoscopic procedures and follow-up of the children were recored. The number of acute pancreatitis attacks, visual analogue scale (VAS) scores of the abdominal pain, and the diameter of pancreatic duct before and after ERCP were compared.Results:A total of 19 children diagnosed as having PD with CP underwent 82 ERCP procedures with the mean number of 4.31 (1-9). The mean number of pancreatic stent replacement was 3.21 (0-8). The success rate of minor papilla cannulation was 97.6% (80/82) with the pain relief rate of 89.5% (17/19) after the first ERCP. ERCP-related complication rate was 4.9% (4/82)without transference to surgery. The mean follow-up time was 55.8 months (9-114 months). The median number of acute pancreatitis attacks decreased from 3.0 to 0 compared with that before the procedure ( Z=-3.839, P<0.001) and the median VAS score decreased from 6 to 1 ( Z=-3.748, P<0.001), both of which had significant difference. However, the median diameters of main pancreatic duct were both 0.35 cm before and after procedure with no significant difference ( Z=-0.699, P=0.484). Conclusion:ERCP is safe and effective to diagnose and treat pediatric patients with PD with CP.

ABSTRACT

Objective:To evaluate the efficacy and safety of clip-with-endoloop method during endoscopic submucosal dissection (ESD) in treatment of early gastric angle cancer and precancerous lesions.Methods:A total of 59 patients with early gastric angle cancer or precancerous lesions underwent ESD from January 2018 to December 2018 were randomly divided into the routine ESD group ( n=28) and the clip-with-endoloop group ( n=31). The frequency of supplementary submucosal injection, ESD procedure time, area of the resected specimen, dissection time, submucosal dissection speed, complete resection rate and complications were compared between the two groups. Results:The frequency of supplementary submucosal injection in the clip-with-endoloop group was less than that in the routine ESD group (2.3±1.1 VS 3.7±1.4, t=4.557, P<0.001). There was no significant difference in the area of the resected specimen between the two groups (12.7±2.6 cm 2 VS 11.7±2.7 cm 2,t=1.485, P=0.143). The ESD procedure time (72.4±24.7 min VS 93.6±28.9 min, t=3.043, P=0.004) and dissection time (67.7±23.3 min VS 88.2±28.3 min, t=3.054, P=0.003) in the clip-with-endoloop group were significantly shorter compared with those in the routine ESD group. The submucosal dissection speed in the clip-with-endoloop group was higher than that in the routine ESD group (20.2±3.2 mm 2/min VS 14.3±3.4 mm 2/min, t=6.879, P<0.001). The complete resection rate was 100.0% in the both groups. No perforation or postoperative bleeding occurred in the two groups. The incidence of intraoperative bleeding in the clip-with-endoloop group was lower than that in the routine ESD group [19.4% (6/31) VS 35.7% (10/28), χ2=1.992, P=0.158]. Conclusion:Clip-with-endoloop method makes ESD procedures easier and faster, with a lower possibility of intraoperative bleeding in treatment of early gastric angle cancer.

ABSTRACT

Objective To investigate the characteristics of population and the changes of disease spectrum in patients treated by endoscopic retrograde cholangiopancreatography ( ERCP ) . Methods Data of 20170 patients, who underwent ERCP in the First People' s Hospital of Hangzhou from May 2004 to February 2018, were enrolled in the retrospective analysis. According to the year of diagnosis and treatment,patients were divided into 2004-2008, 2009-2013, and 2014-2018 group; according to the postoperative diagnosis of ERCP, they were divided into biliary tract diseases ( including calculus, benign stenosis, malignant stenosis, and other causes ) and pancreatic diseases ( including acute pancreatitis, chronic pancreatitis, pancreatic malignant tumor, and other causes ) group; and according to the age, they were divided into the younger age (0-18 years old), young and middle age (19-65 years old), old age (66-85 years old), and advanced age (>85 years old) group. Statistical analysis was performed in the different groups. Results Among the 20170 patients, there were 10260 males and 9910 females, with age of 62. 65± 17. 11 years. The proportion of the younger age group and the advanced age group was 1. 04%( 24/2308 ) , 1. 69% ( 127/7520 ) , 2. 39% ( 247/10342 ) , and 2. 95% ( 68/2308 ) , 4. 19%( 315/7520 ) , 6. 15% ( 636/10342 ) , respectively, in the 2004-2008, 2009-2013 and 2014-2018 subgroups, with a rising trend (P<0. 017). A total 20032 patients had a clear postoperative diagnosis, including 15618 ( 77. 97%) of biliary diseases and 4414 ( 22. 03%) of pancreatic diseases. Biliary stones accounted for the majority of biliary diseases (63. 2%, 9863/15618), and its proportion increased from 59. 9% ( 1191/1987 ) in 2004-2008 to 64. 5% ( 5118/7939 ) in 2014-2018 ( P= 0. 000 ) . Acute pancreatitis accounted for the majority of pancreatic diseases (67. 4%, 1973/4414), and its proportion increased from 52. 4% ( 162/309) in 2004-2008 to 69. 9% ( 1636/2340) in 2014-2018 ( P=0. 000) . The top 3 diseases in the younger group and the advanced age group were acute pancreatitis ( 32. 58%, 129/396) , biliary stones ( 25. 25%, 100/396 ) , chronic pancreatitis ( 22. 22%, 88/396 ) , and biliary stones (56. 46%, 568/1006), malignant biliary stenosis (12. 52%, 126/1006), benign biliary stricture ( 10. 34%, 104/1006) , respectively. Conclusion The main disease of patients receiving ERCP is biliary stone, and the proportion of acute pancreatitis is increased. The overall age of the patients is old, and the proportion of the elderly and underaged patients is gradually increasing. Biliary diseases and pancreatic diseases are the main diseases in elderly patients and younger patients, respectively.

ABSTRACT

Objective To investigate the efficacy and safety of endoscopic ultrasound-guided gallbladder drainage ( EUS-GBD) for patients with acute cholecystitis, who are unfit for cholecystectomy. Methods Patients who underwent EUS-GBD at Hangzhou First People′s Hospital from April 2015 to December 2016 were enrolled in this study. Clinical data were collected, and effectiveness and complications were analyzed. Results EUS-GBD was achieved in all 5 patients, and the mean procedure time of EUS-GBD was 26. 0±3. 1 min. Double pigtail plastic stents were successfully placed in 4 patients. A nasobiliary drainage tube was placed in 1 patient and the tube was endoscopically cut 5 days after procedure acting as internal drainage. All patients recovered without complications and no procedure-related death occurred. During the follow-up period (46-692 d), no patient experienced recurrent cholecystitis and stent migration. Conclusion At an experienced endoscopic center, EUS-GBD is a safe, effective and minimally invasive method for patients with acute cholecystitis and high surgical risk.

ABSTRACT

Objective To study the efficacy and safety of endobiliary radiofrequency ablation (RFA) with stent placement in treatment of unresectable extrahepatic cholangiocarcinoma (EHCC).Methods The patients with unresectable EHCC in Hangzhou First People's Hospital between October 2013 and January 2015 were enrolled in a prospective, randomized, single-blind cohort study, and were assigned randomly into two groups: RFA+stent group and stent-only group.The jaundice fade time, stent patency period, overall survival rate, and postoperative adverse events were analyzed between two groups.Results Among 59 patients with non-resectable EHCC, 28 were divided into RFA+stent group, and 31 were in stent-only group.There was no statistical difference in preoperative serum total bilirubin between the two groups.Mean serum bilirubin decrease time was significantly lower in the RFA+stent group than that in the stent-only group[17.9 d(7-22 d) VS 29.9 d(10-55 d),P=0.03].The biliary patency period in RFA+stent group was significantly longer than that of stent-only group (8.9 months VS 4.5 months, P=0.02).The mean survival time in RFA+stent group was significantly longer than that of stent-only group[13.3 months(6.2-16.5 months) VS 8.6 months(4.5-11.7 months), P=0.000).Incidence of postoperative adverse events showed no statistical difference between the two groups(P=0.727).Conclusion RFA with stent placement is effective and safe as a palliative measure in the treatment of non-resectable EHCC, and it can significantly shorten the jaundice fade time, prolong the biliary patency period and overall survival, while without increase of the incidence of adverse events.

ABSTRACT

Objective To evaluate the safety and efficacy of endoscopic retrograde cholangiopancreatography (ERCP) for the diagnosis and treatment of pancreas divisum(PD) associated with recurrent acute pancreatitis(RAP) in children and teenagers. Methods Data of patients with symptomatic PD associated with RAP under 18 years old who were diagnosed and treated with ERCP from January 2011 to January 2015 were retrospectively analyzed. Patients with complete pancreas divisum underwent endoscopic minor sphincterotomy combined with dorsal duct stenting ( ESCS ) , and those with incomplete pancreas divisum underwent bi?papilla endoscopic sphincterotomy combined with dorsal duct stenting ( Bi?ESCS ) . ERCP?related data, complications were recorded. Long?term follow?up was conducted for procedure related complications. Results Nine patients with symptomatic PD associated with RAP were firstly diagnosed. A total of 18 ERCP procedures were performed in these patients, with success rate of 100. 0% ( 18/18) in the minor papilla cannulation, and mild ERCP?related complication rate of 11. 1% ( 2/18) . One was acute mild pancreatitis and the other was hyperamylasemia. During follow?up from 3 to 60 months, all patients had pain relief, among whom 7 were asymptomatic, with no onset of acute pancreatitis. Dorsal ducts of all patients were not obviously dilated in MRCP or CT scan. All patients gained weight and presented normal physical and intelligence development. Conclusion Symptomatic PD associated with RAP can be completely diagnosed with ERCP . ESCS and Bi?ESCS are safe and effective endoscopic treatment techniques for pediatric cases.
