RESUMO

BACKGROUND AND AIM: Some patients with functional gastrointestinal disorders exhibit pancreatic dysfunctions and pancreatic enzyme abnormalities. Thus, we aimed to clarify whether significant differences in clinical characteristics, prevalence of pancreatic enzyme abnormalities, duodenal inflammation, and protease-activated receptor 2 (PAR2) expression levels related to hypersensitivity exist between functional dyspepsia (FD) alone and FD-irritable bowel syndrome (IBS) overlap group. METHODS: Ninety-three patients based on the Rome IV criteria, FD alone (n = 44) and FD overlapped with IBS (n = 49) group were enrolled. The patients scored their own clinical symptoms after consuming high-fat meals. Serum trypsin, PLA2, lipase, p-amylase, and elastase-1 levels were measured. PAR2, eotaxin-3, and TRPV4 mRNA levels in duodenum were determined using real-time polymerase chain reaction methods. PRG2- and PAR2 in the duodenum were evaluated using immunostaining. RESULTS: FD score and global GSRS in patients with FD-IBS overlap were significantly higher than FD alone. Although the prevalence of pancreatic enzyme abnormalities in patients with FD alone was significantly (P < 0.01) higher than that in FD-IBS overlap, the ratio of aggravation of clinical symptoms following high-fat intake in patients with FD-IBS overlap was significantly higher (P = 0.007) than that in patients with FD alone. PAR2- and PRG2-double positive cells were localized in the degranulated eosinophils in the duodenum of patients with FD-IBS overlap. The number of PAR2- and PRG2-double positive cells in FD-IBS overlap was significantly (P < 0.01) higher than FD alone. CONCLUSIONS: Pancreatic enzyme abnormalities and PAR2 expression on degranulated eosinophils infiltrations in the duodenum may be associated with the pathophysiology of patients with FD-IBS overlap in Asian populations.

RESUMO

OBJECTIVES: Interventional endoscopic ultrasonography is performed for various situations that require drainage, after which stent migration is the most severe adverse event. Several lumen-apposing metal stents (LAMS) and covered self-expandable metal stents (CSEMS) provide antimigration systems; however, their anchoring ability has not been studied well. Therefore, we measured and compared the anchoring force (ACF) of commercially available LAMS and CSEMS. METHODS: Anchoring force was measured for five types of LAMS (NAGI, SPAXUS, Plumber, and AXIOS 8 and 10 mm) and seven types of CSEMS (BCL, SHCL, BCG, BPD [four types of HANAROSTENT], HILZO, Niti-S [Spring Stopper], and Wallflex). We created a phantom model for inducing stent migration. It has a rotatable part as a curved fixture, and we measured ACF at angles between 0° and 40°. RESULTS: The mean ACF at 0° and 20° were NAGI 1.50, 1.84 N, SPAXUS 1.73, 1.72 N, Plumber 2.64, 2.03 N, and AXIOS 3.96, 3.61 N, respectively; and BCL 0.48, 0.53 N, Wallflex 0.53, 0.48 N, SHCL 0.64, 0.73 N, HILZO 1.09, 1.09 N, BCG 1.22, 1.20 N, BPD 1.78, 1.67 N, and Spring Stopper 2.29, 2.51 N. CONCLUSION: We measured ACF in LAMS and CSEMS with a new phantom model. The highest value among the LAMS was for the AXIOS and among the CSEMS was for the Spring Stopper. Some of the ACF values varied with the direction of pull. These findings may have a significant impact on stent selection for interventional endoscopic ultrasonography, and this model can be used to evaluate newly developed stents.

RESUMO

BACKGROUND AND AIM: To clarify whether there were any significant differences in clinical symptoms and eating patterns between functional dyspepsia (FD) patients and FD with pancreatic enzyme abnormalities (FD-P) patients as refractory FD, we compared these factors in multicenter studies in Singapore and Japan. METHODS: One hundred ninety-eight consecutive patients presenting with FD (n = 88), FD-P patients (n = 81) based on Rome III classification and controlled group (n = 39) recruited from six institutions in Singapore and Japan. Clinical characteristics, clinical symptoms for dietary fat intake, and eating behaviors were estimated using questionnaires. Anxiety and health-related quality of life were determined by STAI-state/-trait and SF-8, respectively. RESULTS: There were no significant differences in age, sex, BMI, smoking, alcohol intake, past medical history, and history of allergy in FD and FD-P patients between Singapore and Japan. There were no significant differences in FD subtypes, gastrointestinal symptom rating scale score, severity of FD symptoms, and eating pattern in Singapore and Japan. Moreover, there were significant differences in certain eating behaviors between FD and FD-P patients in Singapore and Japan. Interestingly, epigastric pain and early satiety following fat meals in FD-P patients were significantly (P = 0.003 and P = 0.008, respectively) higher compared with those in FD patients in Japan. Physical component score in FD-P patients was significantly (P = 0.019) disturbed compared with those in FD patients in Japan. CONCLUSIONS: Epigastric pain and early satiety following fat meals in FD-P patients may be useful tools to differentiate FD-P patients from FD patients in Japan.

RESUMO

BACKGROUND: The diagnosis of chronic pancreatitis (CP) using endoscopic ultrasound (EUS) criteria, referred to as the Rosemont classification (RC), has been widely performed. However, the validity of the RC, which was based on expert opinion, is still controversial. If EUS findings are associated with CP, then they should be associated with risk factors for CP. In this study, to verify the appropriateness of the RC and each EUS finding, we performed a retrospective analysis from the viewpoint of risk factors for CP. SUMMARY: Three hundred and forty-four patients were enrolled in this study. Clinical background characteristics that associate with CP were alcohol intake, smoking, history of acute pancreatitis (AP), and age. The correlation between EUS criteria for CP and clinical background was investigated. All EUS findings except the presence of cysts showed significant correlations with one or 2 of the 3 following factors: ethanol (EtOH) intake, smoking status, and history of AP. Results of the univariate and multivariate analyses showed that 3 factors (EtOH intake, smoking, and history of AP) other than age were positively correlated with the RC. Moreover, the risk of progression from normal to consistent CP to indeterminate and suggestive CP was found to increase with increasing EtOH intake. Key Messages: The RC and each EUS finding was validated from the viewpoint of risk factors for CP.

RESUMO

BACKGROUND AND STUDY AIM: Management of bile duct stones (BDSs) in patients with surgically altered anatomies (SAAs) remains challenging. An endoscopic ultrasound-guided antegrade (EUS-AG) procedure and double-balloon enteroscopy-assisted endoscopic retrograde cholangiography (DB-ERC) have been used to remove BDSs from patients with SAAs. However, few comparative data have been reported. Therefore, we compared the efficacy and safety of the techniques. METHODS: This was a single-center retrospective study. Patients with SAA who underwent the EUS-AG procedure or DB-ERC to remove intra- or extra-BDSs between November 2010 and March 2020 were included. The primary outcome was the technical success rate, defined as stent insertion or stone removal during the initial session. The secondary outcomes were the procedure time, incidence of adverse events (AEs), and complete stone removal rate. RESULTS: Of the 54 patients enrolled, 23 underwent the EUS-AG procedure and 31 DB-ERC. The technical success rates of EUS-AG and DB-ERC were 87.0% and 64.5%, respectively (P = 0.11). The procedure time was significantly shorter in the EUS-AG group than in the DB-ERC group (51.9 ± 15.4 vs 72.6 ± 32.2 min; P = 0.01), and the early AE rates were 26.1% and 12.9%, respectively (P = 0.71). The complete stone removal rates in patients who underwent previous stone removal were 94.1% in the EUS-AG group and 85.7% in the DB-ERC group (P = 0.61). CONCLUSION: The EUS-AG afforded technical success and complete stone removal rates comparable with those of DB-ERC, but the former procedure was shorter. The AE rate was acceptable.

RESUMO

OBJECTIVES: Recent guidelines suggest that imaging surveillance be conducted for 5 years for patients with at most one high-risk feature. If there were no significant changes, surveillance is stopped. We sought to validate this follow-up strategy. METHODS: In study 1, data were analysed for 392 patients with intraductal papillary mucinous neoplasms (IPMNs) and at most one high-risk feature who were periodically followed up for more than 1 year with imaging tests. In study 2, data were analysed for 159 IPMN patients without worsening high-risk features after 5 years (stop surveillance group). RESULTS: In study 1, pancreatic cancer (PC) was identified in 12 patients (27.3%) in the endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) indication group and none in the non-EUS-FNA indication group (P < 0.01). In the EUS-FNA indication group, 11 patients (25%) died, whereas 29 (8.3%) died in the non EUS-FNA indication group (P < 0.01). In study 2 (stop surveillance group), PC was identified in three patients (1.9%) at 84, 103 and 145 months. CONCLUSIONS: PC risk and mortality for IPMNs not showing significant change for 5 years is likely to be low, and the non-EUS-FNA indication can provide reasonable decisions. However, three patients without worsening high-risk features for 5 years developed PC. The stop surveillance strategy should be reconsidered. KEY POINTS: • The AGA guidelines provide reasonable clinical decisions for the EUS-FNA indication. • In stop surveillance group, PC was identified in 3 patients (1.9%). • In stop surveillance group, 2 of 3 PC patients died from PC. • Risk of pancreatic cancer in "stop surveillance" group is not negligible.

RESUMO

Background/Objective: Interventional endoscopic ultrasound (I-EUS) is technically difficult and has risks of severe adverse events due to the scarcity of dedicated endoscopes and tools. A new EUS scope was developed for I-EUS and was modified to increase the puncture range, reduce the blind area, and overcome guidewire difficulties. We evaluated the usefulness and safety of a new EUS scope compared to a conventional EUS scope. Methods: All I-EUS procedures were performed at Juntendo University Hospital from April 2020 to April 2022. The primary outcomes included the procedure time and fluoroscopy time. The secondary outcomes included the technical success rate and the rates of procedure-related adverse events. Clinical data were retrospectively reviewed and statistically analyzed between the new and conventional EUS scopes. Results: In total, 143 procedures in 120 patients were analyzed. The procedure time was significantly shorter with the new EUS scope, but the fluoroscopy time was not different. Among the patients only undergoing EUS-guided biliary drainage (EUS-BD), 79 procedures in 74 patients were analyzed. Both the procedure time and fluoroscopy time were significantly shorter with the new EUS scope. Multivariate analysis revealed that a new EUS scope and use of covered metal stents could reduce the fluoroscopy time. The technical success rate and the adverse event rate were not significantly different between the total I-EUS and the EUS-BD only groups. However, the conventional scope showed stent deviation during stent placement, which did not happen with the new scope. Conclusions: The new EUS scope reduced procedure time for total I-EUS and fluoroscopy time for EUS-BD compared to a conventional EUS scope because of the improvement suitable for I-EUS.

RESUMO

A bronchobiliary fistula (BBF) is an uncommon but severe complication after radiofrequency ablation (RFA). However, the definitive salvage methods are controversial. We herein report a patient with hepatocellular carcinoma with hepatic abscess and BBF following RFA. We also review previous reports of BBF after RFA. The patient was a man in his 70s who underwent RFA for recurrent hepatocellular carcinoma in the subphrenic area. Despite percutaneous transhepatic abscess drainage, bilioptysis persisted. Finally, the BBF was occluded with an endobronchial Watanabe spigot under fiber-optic bronchoscopy. Placing an endobronchial Watanabe spigot should be considered as a salvage therapy for refractory BBF following RFA.

RESUMO

BACKGROUND: There have been few reports of covered self-expandable metallic stent (SEMS) placement for malignant hilar-biliary obstruction (MHBO) because of risk of biliary branch obstruction. We studied feasibility and efficacy of 6-mm-diameter, slim, fully covered SEMS (SFCSEMS) in a relatively large cohort. METHODS: We retrospectively evaluated SFCSEMS in unresectable MHBO from December 2016 to September 2021 in Juntendo University Hospital. RESULTS: We enrolled consecutive 54 unresectable MHBO (18 bile duct, 11 gallbladder, eight pancreatic, two hepatocellular, and 15 metastatic cancer cases) including Bismuth-type II (n = 11), III (n = 17), and IV (n = 26), and placed two (n = 35) or three (n = 19) SFCSEMS. The technical and clinical success rate was 100% and 92.5%, respectively, with 76.3 min of mean procedure time. Recurrent biliary obstruction (RBO) was observed in 35.2% and the median cumulative time to RBO (TRBO) was 181 days. Other adverse events were 11.1% (four mild-pancreatitis, one segmental-cholangitis, and one cholecystitis). There were no failed cases of stent exchange and second SFCSEMS (n = 6) showed significantly lower RBO (16.7% vs. 81.8%, P = .0364) and longer TRBO (undefined vs 86 days; P = .0617) than plastic stent (n = 11). CONCLUSIONS: Endoscopic placement of SFCSEMS for unresectable MHBO was effective and feasible with low incidence of segmental cholangitis, and exchange strategy of SFCSEMS was promising.

RESUMO

This study investigated the impact of partial splenic embolization (PSE) on portal hypertensive gastropathy (PHG). We retrospectively analyzed endoscopic findings and the portal venous system of 31 cirrhotic patients with PHG. The improved group was defined as the amelioration of PHG findings using the McCormack classification. Child-Pugh scores of the improved group (18 of 31 patients) were significantly lower compared with those of the non-improved group (p = 0.018). The changes in the diameters of the portal trunk and those of the spleno-portal junction and spleen hilum in the splenic vein of the improved group were significantly larger than those of the non-improved group (p = 0.007, p = 0.025, and p = 0.003, respectively). The changes in the diameters of the portal vein and splenic hilum of the splenic vein showed significant correlations with Child-Pugh score (r = 0.386, p = 0.039; r = 0.510, p = 0.004). In a multivariate analysis of baseline factors related to the improved group, Child-Pugh grade A was significantly associated with the improvement of PHG (odds ratio 6.875, p = 0.033). PSE could be useful for PHG, especially in patients with Child-Pugh grade A, at least in the short term.

RESUMO

One of the reasons for groove pancreatitis is caused by the leakage of pancreatic juice into the space between the pancreatic head, descending duodenum, and common bile duct. Endoscopic drainage of Santorini's duct (SD) via the minor papilla is reportedly efficacious but can be difficult due to duodenal stenosis. We report Santorini's duct drainage using endoscopic ultrasonography-guided pancreaticogastrostomy (EUS-PGS) for a case of groove pancreatitis with gastric outlet obstruction. Gastric outlet obstruction was improved after 7 months of EUS-PGS with internal drainage through the Santorini's duct/minor papilla. EUS-PGS may be effective for treating groove pancreatitis with duodenal stenosis. This is the first report of groove pancreatitis with duodenal stenosis, the symptoms of which were improved by EUS-PGS.

RESUMO

Background and Objectives: EUS-guided hepaticogastrostomy (EUS-HGS) is an effective salvage procedure when conventional endoscopic transpapillary biliary drainage is difficult or fails. However, the risk of stent migration into the abdominal cavity has not been resolved completely. In this study, we evaluated a newly developed partially covered self-expandable metallic stent (PC-SEMS) that has a spring-like anchoring function on the gastric side. Methods: This retrospective pilot study took place at four referral centers in Japan between October 2019 and November 2020. We enrolled 37 cases consecutively who underwent EUS-HGS for unresectable malignant biliary obstruction. Results: The rates of technical and clinical success were 97.3% and 89.2%, respectively. Technical failures included one case in which the stent was dislocated during the removal of the delivery system, requiring additional EUS-HGS on another branch. Early adverse events (AEs) were observed in four patients (10.8%): two with mild peritonitis (5.4%) and one each (2.7%) with fever and bleeding. No late AEs were observed during the mean follow-up period of 5.1 months. All recurrent biliary obstructions (RBOs) were stent occlusions (29.7%). The median cumulative time to RBO was 7.1 months (95% confidence interval, 4.3 to not available). Although stent migration in which the stopper was in contact with the gastric wall on follow-up computed tomography was observed in six patients (16.2%), no migration was observed. Conclusions: The newly developed PC-SEMS is feasible and safe for the EUS-HGS procedure. The spring-like anchoring function on the gastric side is an effective anchor preventing migration.

RESUMO

OBJECTIVES: The Japan Pancreas Society introduced the concept of early chronic pancreatitis (ECP) in 2009, but its epidemiology remains unclear. This study investigated challenges in ECP diagnosis. METHODS: Early chronic pancreatitis was diagnosed in 4 cohorts between April 2019 and November 2021 using the Clinical Diagnostic Criteria for Chronic Pancreatitis 2019. These cohorts included patients with abdominal/back pain, abnormal pancreatic enzyme levels, ECP suspected due to other reasons, and those who underwent endoscopic ultrasonography for other diseases. RESULTS: A total of 2502 cases were analyzed and 150 (40 alcoholic and 110 nonalcoholic) cases with ECP findings on endoscopic ultrasonography were included. Early chronic pancreatitis was confirmed in 14 cases (9%), including 9 (22.5%) alcoholic and 5 (4.5%) nonalcoholic cases. Early chronic pancreatitis was confirmed in 15%, 0%, 2.2%, and 0.13% cases in the 4 cohorts, respectively. Early chronic pancreatitis was confirmed in 10 (48%) of the 21 (14%) cases with pancreatic pain. CONCLUSIONS: Early chronic pancreatitis diagnostic rate was low, particularly in nonalcoholic cases, but was slightly higher in cases with pancreatic pain. The diagnostic rate was highest in the abdominal/back pain group. Further studies are required to establish appropriate diagnostic criteria for ECP.

RESUMO

This prospective study investigated the impact of cabozantinib exposure on proteinuria and muscle toxicity, in a cohort of 14 Japanese patients with unresectable hepatocellular carcinoma (uHCC). We measured the trough concentration of cabozantinib (Ctrough) weekly for 6 weeks after starting treatment. Although the initial dose was less than 60 mg in most cases, dose interruption occurred in 79%, primarily because of proteinuria and/or malaise. The median and coefficient of variation of maximum Ctrough at 7−42 d were 929.0 ng/mL and 59.2%, respectively. The urinary protein-to-creatinine ratio (UPCR), serum creatine kinase, and serum aldolase values were all significantly elevated following treatment. Moreover, maximum changes in serum creatine kinase and aldolase were significantly associated with maximum Ctrough (r = 0.736, p < 0.01; r = 0.798, p < 0.001; respectively). Receiver operating characteristic (ROC) curve analysis showed that changes in serum creatine kinase ≥70.5 U/L and aldolase ≥6.1 U/L from baseline relatively accurately predicted inclusion in the high-maximum Ctrough (≥929.0 ng/mL) group, with an area under the ROC of 0.929 and 0.833, respectively. Measurement of serum creatine kinase and aldolase may increase the clinical usefulness of cabozantinib treatment for uHCC and help alleviate difficulties with dose adjustments.

RESUMO

OBJECTIVES: Endoscopic ultrasound/endosonography-guided pancreaticogastrostomy (EUS-PGS) is a useful alternative when endoscopic retrograde pancreatography is difficult. Recently, many procedures, including peroral pancreatoscopy (POPS), have been performed through the mature fistula (MF) created by EUS-PGS. We evaluate the efficacy and safety of POPS to diagnose and treat pancreatic ductal stricture/pancreato-jejunal anastomotic stricture (PDS/PJAS) through the MF. METHODS: Twenty patients underwent EUS-PGS; 13 of these underwent POPS through the MF at Juntendo University Hospital. All patients were studied retrospectively in terms of technical and clinical success rates and adverse events (AEs). RESULTS: The technical and clinical success rates of EUS-PGS were 95% and 100%. The early and late AEs rates were 20% and 15%. The technical success rate of POPS was 100%, with one AE. Biopsy of PDS/PJAS under POPS guidance revealed recurrent/residual intrapapillary mucinous adenoma (3 patients) and benign fibrotic stricture (10 patients). In the latter patients, multiple plastic stents were placed to dilate PDS/PJAS. Four patients with improvement of PDS/PJAS were stent free, but the remaining patients were not yet. CONCLUSIONS: Endoscopic ultrasound/endosonography-guided pancreaticogastrostomy and various procedures (including POPS) performed through the MF are feasible and effective and can diagnose and treat PDS/PJAS with acceptable AEs rates.

RESUMO

Endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) is an effective biliary drainage procedure in adult cases with difficult biliary access. However, there have been no reports on this procedure being used in pediatric cases. We successfully performed EUS-HGS in a pediatric case with a surgically altered anatomy. A standard convex-type echoendoscope and standard devices were used, and there were no device-related complications. The benefit of EUS-HGS for pediatric patients was avoidance of a percutaneous tube, which is difficult to maintain in active children. The accumulation of further cases and performance of a prospective study are warranted to standardize and expand the experience with this procedure.
