Contains fulltext : 305450.pdf (Publisher’s version ) (Open Access), BACKGROUND: Percutaneous cholangioscopy (PerC) offers an alternative for patients with an inaccessible biliary tree. This systematic review and meta-analysis aimed to evaluate the performance of this technique. METHODS: A search in Medline, Cochrane and ClinicalTrials.gov databases was performed for studies assessing PerC up to October 2022. The primary outcome was diagnostic success, defined as successful stone identification or stricture workup. Secondary outcomes included therapeutic success (stone extraction, stenting) and complication rate. A subgroup analysis compared previous-generation and modern cholangioscopes. We performed meta-analyses using a random-effects model and the results were reported as percentages with 95% confidence interval (CI). RESULTS: Fourteen studies (682 patients) were eligible for analysis. The rate of diagnostic success was 98.7% (95%CI 97.6-99.8%; I(2)=31.19%) and therapeutic success was 88.6% (95%CI 82.8-94.3%; I(2)=74.92%). Adverse events were recorded in 17.1% (95%CI 10.7-23.5%; I(2)=77.56%), of which 15.9% (95%CI 9.8-21.9%; I(2)=75.98%) were minor and 0.6% (95%CI 0.1-1.2%; I(2)=0%) major. The Spyglass system showed null heterogeneity for all outcomes; compared with older-generation endoscopes it offered comparable diagnostic success, but yielded significantly superior therapeutic success (96.1%, 95%CI 90-100%; I(2)=0% vs. 86.4%, 95%CI 79.2-93.6%; I(2)=81.41%; P=0.02]. CONCLUSION: PerC, especially using currently available cholangioscopes, is associated with high diagnostic and therapeutic success.

- Abstract
01 februari 2023, Item does not contain fulltext, BACKGROUND: Digital single-operator pancreatoscopy (DSOP)-guided lithotripsy is a novel treatment modality for pancreatic endotherapy, with demonstrated technical success in retrospective series of between 88 % and 100 %. The aim of this prospective multicenter trial was to systematically evaluate DSOP in patients with chronic pancreatitis and symptomatic pancreatic duct stones. METHODS: Patients with symptomatic chronic pancreatitis and three or fewer stones ≥ 5mm in the main pancreatic duct (MPD) of the pancreatic head or body were included. The primary end point was complete stone clearance (CSC) in three or fewer treatment sessions with DSOP. Current guidelines recommend extracorporeal shock wave lithotripsy (ESWL) for MPD stones > 5 mm. A performance goal was developed to show that the CSC rate of MPD stones using DSOP was above what has been previously reported for ESWL. Secondary end points were pain relief measured with the Izbicki pain score (IPS), number of interventions, and serious adverse events (SAEs). RESULTS: 40 chronic pancreatitis patients were included. CSC was achieved in 90 % of patients (36/40) on intention-to-treat analysis, after a mean (SD) of 1.36 (0.64) interventions (53 procedures in total). The mean (SD) baseline IPS decreased from 55.3 (46.2) to 10.9 (18.3). Overall pain relief was achieved in 82.4 % (28/34) after 6 months of follow-up, with complete pain relief in 61.8 % (21/34) and partial pain relief in 20.6 % (7/34). SAEs occurred in 12.5 % of patients (5/40), with all treated conservatively. CONCLUSION: DSOP-guided endotherapy is effective and safe for the treatment of symptomatic MPD stones in highly selected patients with chronic pancreatitis. It significantly reduces pain and could be considered as an alternative to standard ERCP techniques for MPD stone treatment in these patients.

- Abstract
Item does not contain fulltext, BACKGROUND: Over 20 susceptibility single-nucleotide polymorphisms (SNP) have been identified for esophageal adenocarcinoma (EAC) and its precursor, Barrett esophagus (BE), explaining a small portion of heritability. METHODS: Using genetic data from 4,323 BE and 4,116 EAC patients aggregated by international consortia including the Barrett's and Esophageal Adenocarcinoma Consortium (BEACON), we conducted a comprehensive transcriptome-wide association study (TWAS) for BE/EAC, leveraging Genotype Tissue Expression (GTEx) gene-expression data from six tissue types of plausible relevance to EAC etiology: mucosa and muscularis from the esophagus, gastroesophageal (GE) junction, stomach, whole blood, and visceral adipose. Two analytical approaches were taken: standard TWAS using the predicted gene expression from local expression quantitative trait loci (eQTL), and set-based SKAT association using selected eQTLs that predict the gene expression. RESULTS: Although the standard approach did not identify significant signals, the eQTL set-based approach identified eight novel associations, three of which were validated in independent external data (eQTL SNP sets for EXOC3, ZNF641, and HSP90AA1). CONCLUSIONS: This study identified novel genetic susceptibility loci for EAC and BE using an eQTL set-based genetic association approach. IMPACT: This study expanded the pool of genetic susceptibility loci for EAC and BE, suggesting the potential of the eQTL set-based genetic association approach as an alternative method for TWAS analysis.

- Abstract
Item does not contain fulltext, BACKGROUND AND AIMS: Percutaneous cholangioscopy (PC) is more complex and invasive than a transpapillary approach, with the need for a large percutaneous tract of 16 French (Fr) on average in order to advance standard percutaneous cholangioscopes. The aim of this study was to investigate whether percutaneous single-operator cholangioscopy (pSOC) using the SpyGlass(™) DS system is feasible, safe, and effective in PC for diagnostic and therapeutic indications. MATERIALS AND METHODS: The data of 28 patients who underwent pSOC in 4 tertiary referral centers were retrospectively analyzed. Technical and clinical success for therapeutic procedures was assessed as well as diagnostic accuracy of pSOC-guided biopsies and visualization. Adverse events and the required number and size of dilatations were reviewed. RESULTS: 25/28 (89%) patients had a post-surgical altered anatomy. The average number of percutaneous dilatations prior to pSOC was 1.25 with a mean dilatation size of 11 French. Histopathology showed a 100% accuracy. Visual impression showed an overall accuracy of 96.4%. Technical and clinical success was achieved in 27/28 (96%) of cases. Adverse events occurred in 3/28 (10.7%) cases. CONCLUSION: pSOC is a feasible, safe, and effective technique for diagnostic and therapeutic indications. It may be considered an alternative approach in clinical cases where gastrointestinal anatomy is altered. It has the potential to reduce peri-procedural adverse events and costs. Prospective randomized-controlled trials are necessary to confirm the previously collected data.

- Abstract
Contains fulltext : 235640.pdf (Publisher’s version ) (Closed access), Genome-wide association studies (GWAS) of esophageal adenocarcinoma (EAC) and its precursor, Barrett's esophagus (BE), have uncovered significant genetic components of risk, but most heritability remains unexplained. Targeted assessment of genetic variation in biologically relevant pathways using novel analytical approaches may identify missed susceptibility signals. Central obesity, a key BE/EAC risk factor, is linked to systemic inflammation, altered hormonal signaling and insulin-like growth factor (IGF) axis dysfunction. Here, we assessed IGF-related genetic variation and risk of BE and EAC. Principal component analysis was employed to evaluate pathway-level and gene-level associations with BE/EAC, using genotypes for 270 single-nucleotide polymorphisms (SNPs) in or near 12 IGF-related genes, ascertained from 3295 BE cases, 2515 EAC cases and 3207 controls in the Barrett's and Esophageal Adenocarcinoma Consortium (BEACON) GWAS. Gene-level signals were assessed using Multi-marker Analysis of GenoMic Annotation (MAGMA) and SNP summary statistics from BEACON and an expanded GWAS meta-analysis (6167 BE cases, 4112 EAC cases, 17 159 controls). Global variation in the IGF pathway was associated with risk of BE (P = 0.0015). Gene-level associations with BE were observed for GHR (growth hormone receptor; P = 0.00046, false discovery rate q = 0.0056) and IGF1R (IGF1 receptor; P = 0.0090, q = 0.0542). These gene-level signals remained significant at q < 0.1 when assessed using data from the largest available BE/EAC GWAS meta-analysis. No significant associations were observed for EAC. This study represents the most comprehensive evaluation to date of inherited genetic variation in the IGF pathway and BE/EAC risk, providing novel evidence that variation in two genes encoding cell-surface receptors, GHR and IGF1R, may influence risk of BE.

- Abstract
Item does not contain fulltext, BACKGROUND: Stenosis of the pancreaticojejunostomy is a well-known long-term complication of pancreaticoduodenectomy. Traditionally, the endoscopic approach consisted of endoscopic retrograde pancreatography (ERP). Endoscopic ultrasound (EUS)-guided intervention has emerged as an alternative, but the success rate and adverse event rate of both treatment modalities are poorly known. We aimed to compare the outcome data of both interventions. METHODS: We performed a systematic literature search using the Pubmed/Medline and Embase databases in order to summarize the available data regarding efficacy and complications of ERP- and EUS-guided pancreatic duct (PD) drainage and compare these outcome data using uniform outcome measures in a multilevel logistic model. RESULTS : 13 studies were included, involving 77 patients who underwent ERP-guided drainage, 145 who underwent EUS-guided drainage, and 12 patients who underwent both modalities. An EUS-guided approach was significantly superior to an ERP-guided approach with regard to pancreatic duct opacification (87 % vs. 30 %; P < 0.001), cannulation success (79 % vs. 26 %; P < 0.001), and stent placement (72 % vs. 20 %; P < 0.001). An EUS-guided approach also appeared superior with regard to clinical outcomes such a pain resolution. The adverse event rate between the two treatment modalities could not be compared due to insufficient data. All included studies were found to be of low quality. CONCLUSION: Based on limited available data, EUS-guided PD intervention appears superior to ERP-guided PD intervention.

- Abstract
Item does not contain fulltext, BACKGROUND AND AIMS: Motorized spiral enteroscopy (MSE) was recently introduced into clinical practice and shown to be safe and effective for antegrade enteroscopy. The aim of the current trial was to prospectively study the efficacy and safety of MSE for visualization of the entire small bowel. METHODS: All consecutive patients with indications for complete enteroscopy meeting the inclusion criteria were enrolled in a prospective observational bicentric trial, starting with antegrade MSE; a retrograde approach was performed if MSE remained incomplete from antegrade. The primary objective was to ascertain the total enteroscopy rate (TER); secondary objectives were diagnostic yield, procedural success, time, depth of maximum insertion (DMI), therapeutic yield, and adverse events (AEs). RESULTS: Thirty patients (16 women, 14 men; median age 64 years [range, 37-100]) were enrolled. Technical success rate of antegrade MSE (advancement beyond the ligament of Treitz) and retrograde MSE (advancement beyond the ileocecal valve [ICV]) were 100% and 100%, respectively. Overall TER was 70%: 16.6% antegrade approach alone and 53.4% bidirectional approach. Median antegrade DMI distal from the ligament of Treitz was 490 cm (range, 160-600); median insertion time 26 minutes (range, 15-110). The median retrograde DMI beyond the ICV was 120 cm (range, 40-600), and median insertion time was 17 minutes (range, 1-68). Overall diagnostic and therapeutic yields were 80% and 86.7%, respectively. Overall AE rate was 16.7%. No serious AEs occurred. CONCLUSIONS: This prospective study showed that complete enteroscopy is feasible with MSE, either from antegrade alone or bidirectionally, with high success rates and short procedural duration. These results justify further evaluation of MSE in a large prospective multicenter study, preferably with inclusion of a control group. (Clinical trial registration number: NCT03438695.).

- Abstract
Item does not contain fulltext, OBJECTIVE: Currently available methods for small bowel endoscopy are often time consuming; motorised PowerSpiral Enteroscopy (PSE) is a further development of spiral enteroscopy to facilitate the approach to the small bowel. The aim of this bicentric prospective trial was to study feasibility and yield of peroral PSE. DESIGN: Consecutive patients with suspected small bowel disease and indication for antegrade enteroscopy were included in two tertiary referral centres. Primary objective was diagnostic yield of antegrade PSE. Secondary objectives included technical success (defined as successful endoscope insertion at least to ligament of Treitz), depth of maximum insertion (DMI), median insertion time to DMI, rate of therapeutic procedures and adverse events. RESULTS: During a 30-month period, 140 procedures were performed on 132 patients (58 female, 74 male; median age: 68 (20-100) years) under general anaesthesia. Overall diagnostic yield of PSE was 74.2%; with 68.2% of procedures including some form of endotherapy. Technical success rate of PSE was 97%; median DMI was 450 cm (0-600) with a median insertion time to DMI of 25 min (3-122). Antegrade panenteroscopy to the cecum was achieved in 14 cases (10.6%). Overall adverse event (AE) rate was 14.4%; two major serious AEs occurred (1.5%), one delayed perforation, one bleeding from Mallory-Weiss lesion. CONCLUSION: This pilot clinical trial demonstrates that PSE is effective for diagnostic and therapeutic antegrade enteroscopy and may compare favourably with traditional methods of deep enteroscopy in ease of use and procedural duration. More comparative data are required to assess clinical application and safety of PSE. TRIAL REGISTRATION NUMBER: NCT02965209.

Contains fulltext : 235632.pdf (Publisher’s version ) (Open Access), BACKGROUND: Although colonoscopy is the gold standard for colorectal cancer screening, colonic looping may make complete colonoscopy challenging. Commonly available stiffening device colonoscopy has been described as helpful but not effective enough to prevent looping. In this context the effect on cecal intubation time and rate was described differently in various studies and in some studies had no impact on cecal intubation time at all. The aim of this study was to evaluate whether a novel colonoscope with gradual stiffness (Fujifilm EC760R-V/I- flexibility adjuster, Tokyo, Japan) using four significantly different grades of stiffness can be an alternative to established devices in terms of loop prevention, cecal intubation rate and time, adverse events, and patient/examiner satisfaction. METHODS: Consecutive patients without previous colorectal surgery were analyzed retrospectively. Colonoscopy was performed with the new colonoscope and performance characteristics, including time to cecum, withdrawal time, total examination time, and patient and endoscopist satisfaction were recorded. RESULTS: Among 180 consecutive procedures, 98.3% of examinations were complete to the cecum. The endoscopic flexibility adjuster was used in 150 of 180 cases (83.3%). Overall, the device was scored by the examiner as helpful to prevent looping in 146 of the 150 cases (97.7%). Mean cecal intubation time was 6.5 min, with 35% of examination performed in under 5 min with a mean withdrawal time of 7 min. Mean total examination time was 18 min. Patient satisfaction was rated as high in all examinations performed. CONCLUSION: The new flexibility adjuster colonoscope was shown to be helpful in loop prevention, allowed for fast and successful cecal intubation, and led to a high rate of patients satisfaction.

- Abstract
Item does not contain fulltext, BACKGROUND: Colorectal endoscopic mucosal resection (EMR) is an effective, safe, and minimally invasive treatment for large lateral spreading and sessile polyps. The reported high recurrence rate of approximately 20% is however one of the major drawbacks. Several endoscopic interventions have been suggested to reduce recurrence rates. We conducted a systematic review and meta-analysis to assess the efficacy of endoscopic interventions targeting the EMR margin to reduce recurrence rates. METHODS: We searched in PubMed and Ovid for studies comparing recurrence rates after interventions targeting the EMR margin with standard EMR. The primary outcome was the recurrence rate at the first surveillance colonoscopy (SC1) assessed histologically or macroscopically. For the meta-analysis, risk ratios (RRs) were calculated and pooled using a random effects model. The secondary outcome was post-procedural complication rates. RESULTS: Six studies with a total of 1335 lesions were included in the meta-analysis. The techniques performed in the intervention group targeting the resection margin were argon plasma coagulation, snare tip soft coagulation, extended EMR, and precutting EMR. The interventions reduced the adenoma recurrence rate with more than 50%, resulting in a pooled RR of 0.37 (95% CI 0.18, 0.76) comparing the intervention group with the control groups. Overall post-procedural complication rates did not increase significantly in the intervention arm (RR 1.30; 95% CI 0.65, 2.58). CONCLUSION: Interventions targeting the EMR margin decrease recurrence rates and may not result in more complications.

The article titled "Surgery versus Endoscopic therapy for Mirizzi Syndrome (SEIZE)-study: A Multicentre International Experience" compares the outcomes and safety of digital single-operator cholangioscopy (dSOC)-guided lithotripsy with the surgical approach for the management of Mirizzi syndrome. Mirizzi syndrome is a condition that affects the bile ducts and is typically treated surgically. However, the introduction of dSOC has allowed for an endoscopic approach. The study found that dSOC was highly effective in removing intraductal stones and had superior safety compared to surgery, even in patients with underlying comorbidity. The use of dSOC also reduced the need for subsequent surgery and cholecystectomy in two-thirds of patients. The authors advocate for dSOC as the primary modality in the management of Mirizzi syndrome. [Extracted from the article]

- Abstract
Contains fulltext : 220009.pdf (Publisher’s version ) (Closed access), BACKGROUND: Obesity is a major risk factor for esophageal adenocarcinoma (EA) and its precursor Barrett's esophagus (BE). Research suggests that individuals with high genetic risk to obesity have a higher BE/EA risk. To facilitate understanding of biological factors that lead to progression from BE to EA, the present study investigated the shared genetic background of BE/EA and obesity-related traits. METHODS: Cross-trait linkage disequilibrium score regression was applied to summary statistics from genome-wide association meta-analyses on BE/EA and on obesity traits. Body mass index (BMI) was used as a proxy for general obesity, and waist-to-hip ratio (WHR) for abdominal obesity. For single marker analyses, all genome-wide significant risk alleles for BMI and WHR were compared with summary statistics of the BE/EA meta-analyses. RESULTS: Sex-combined analyses revealed a significant genetic correlation between BMI and BE/EA (r(g) = 0.13, P = 2 × 10(-04)) and a r(g) of 0.12 between WHR and BE/EA (P = 1 × 10(-02)). Sex-specific analyses revealed a pronounced genetic correlation between BMI and EA in females (r(g) = 0.17, P = 1.2 × 10(-03)), and WHR and EA in males (r(g) = 0.18, P = 1.51 × 10(-02)). On the single marker level, significant enrichment of concordant effects was observed for BMI and BE/EA risk variants (P = 8.45 × 10(-03)) and WHR and BE/EA risk variants (P = 2 × 10(-02)). CONCLUSIONS: Our study provides evidence for sex-specific genetic correlations that might reflect specific biological mecha-nisms. The data demonstrate that shared genetic factors are particularly relevant in progression from BE to EA. IMPACT: Our study quantifies the genetic correlation between BE/EA and obesity. Further research is now warranted to elucidate these effects and to understand the shared pathophysiology.

- Abstract
Contains fulltext : 220059.pdf (Publisher’s version ) (Closed access), BACKGROUND AND AIMS: Accurately diagnosing indeterminate biliary strictures is challenging but important for patient prognostication and further management. Biopsy sampling under direct cholangioscopic vision might be superior to standard ERCP techniques such as brushing or biopsy sampling. Our aim was to investigate whether digital single-operator cholangioscopy (DSOC) compared with standard ERCP workup improves the diagnostic yield in patients with indeterminate biliary strictures. METHODS: Patients with an indeterminate biliary stricture on the basis of MRCP were randomized to standard ERCP visualization with tissue brushing (control arm [CA]) or DSOC visualization and DSOC-guided biopsy sampling (study arm [SA]). This was a prospective, international, multicenter trial with a procedure-blinded pathologist. RESULTS: The first sample sensitivity of DSOC-guided biopsy samples was significantly higher than ERCP-guided brushing (SA 68.2% vs CA 21.4%, P < .01). The sensitivity of visualization (SA 95.5% vs CA 66.7%, P = .02) and overall accuracy (SA 87.1% vs CA 65.5%, P = .05) were significantly higher in the SA compared with the CA, whereas specificity, positive predictive value, and negative predictive value showed no significant difference. Adverse events were equally low in both arms. CONCLUSIONS: DSOC-guided biopsy sampling was shown to be safe and effective with a higher sensitivity compared with standard ERCP techniques in the visual and histopathologic diagnosis of indeterminate biliary strictures.

- Abstract
Contains fulltext : 229320.pdf (Publisher’s version ) (Closed access), BACKGROUND & AIMS: Esophageal adenocarcinoma (EA) and its premalignant lesion, Barrett's esophagus (BE), are characterized by a strong and yet unexplained male predominance (with a male-to-female ratio in EA incidence of up to 6:1). Genome-wide association studies (GWAS) have identified more than 20 susceptibility loci for these conditions. However, potential sex differences in genetic associations with BE/EA remain largely unexplored. METHODS: Given strong genetic overlap, BE and EA cases were combined into a single case group for analysis. These were compared with population-based controls. We performed sex-specific GWAS of BE/EA in 3 separate studies and then used fixed-effects meta-analysis to provide summary estimates for >9 million variants for male and female individuals. A series of downstream analyses were conducted separately in male and female individuals to identify genes associated with BE/EA and the genetic correlations between BE/EA and other traits. RESULTS: We included 6758 male BE/EA cases, 7489 male controls, 1670 female BE/EA cases, and 6174 female controls. After Bonferroni correction, our meta-analysis of sex-specific GWAS identified 1 variant at chromosome 6q11.1 (rs112894788, KHDRBS2-MTRNR2L9, P(BONF) = .039) that was statistically significantly associated with BE/EA risk in male individuals only, and 1 variant at chromosome 8p23.1 (rs13259457, PRSS55-RP1L1, P(BONF) = 0.057) associated, at borderline significance, with BE/EA risk in female individuals only. We also observed strong genetic correlations of BE/EA with gastroesophageal reflux disease in male individuals and obesity in female individuals. CONCLUSIONS: The identified novel sex-specific variants associated with BE/EA could improve the understanding of the genetic architecture of the disease and the reasons for the male predominance.

- Abstract
Contains fulltext : 229424.pdf (Publisher’s version ) (Closed access), BACKGROUND AND AIMS: Minimally invasive treatments of anastomotic benign biliary stricture (BBS) after orthotopic liver transplantation (OLT) include endoscopic placement of multiple plastic stents or fully covered self-expandable metal stents (FCSEMSs). No multiyear efficacy data are available on FCSEMS treatment after OLT. METHODS: We prospectively studied long-term efficacy and safety of FCSEMS treatment in adults aged≥18 years with past OLT, cholangiographically confirmed BBS, and an indication for ERCP with stent placement. Stent removal was planned after 4 to 6 months, with subsequent follow-up until 5 years or stricture recurrence. Long-term outcomes were freedom from stricture recurrence, freedom from recurrent stent placement, and stent-related serious adverse events (SAEs). RESULTS: In 41 patients, long-term follow-up began after FCSEMS removal (n = 33) or observation of complete distal migration (CDM) (n = 8). On an intention-to-treat basis, the 5-year probability of remaining stent-free after FCSEMS removal or observation of CDM was 48.9% (95% confidence interval [CI], 33.2%-64.7%) among all patients and 60.9% (95% CI, 43.6%-78.2%) among 31 patients with over 4 months of FCSEMS indwell time. In 28 patients with stricture resolution at FCSEMS removal or observed CDM (median, 5.0 months indwell time), the 5-year probability of no stricture recurrence was 72.6% (95% CI, 55.3%-90%). Sixteen patients (39%) had at least 1 related SAE, most commonly cholangitis (n = 10). CONCLUSIONS: By 5 years after temporary FCSEMS treatment of post-OLT BBS, approximately half of all patients remained stent-free on an intention-to-treat basis. Stent-related SAEs (especially cholangitis) were common. FCSEMS placement is a viable long-term treatment option for patients with post-OLT BBS. (Clinical trial registration number: NCT01014390.).

- Abstract
Contains fulltext : 220107.pdf (Publisher’s version ) (Closed access), BACKGROUND AND AIMS: Temporary single, fully covered self-expanding metal stent (FCSEMS) placement for benign biliary strictures (BBSs) associated with chronic pancreatitis (CP) may require fewer interventions than endotherapy with multiple plastic stents and may carry less morbidity than biliary diversion surgery. This study aimed to assess long-term outcomes in CP-associated BBSs after FCSEMS placement and removal. METHODS: In this open-label, multinational, prospective study, subjects with CP and a BBS treated with FCSEMS placement with scheduled removal at 10 to 12 months were followed for 5 years after FCSEMS indwell. Kaplan-Meier analyses assessed BBS resolution and cumulative probability of freedom from recurrent stent placement to 5 years after FCSEMS indwell. RESULTS: One hundred eighteen patients were eligible for FCSEMS removal. At a median of 58 months (interquartile range, 44-64) post-FCSEMS indwell, the probability of remaining stent-free was 61.6% (95% confidence interval [CI], 52.5%-70.7%). In 94 patients whose BBSs resolved at the end of FCSEMS indwell, the probability of remaining stent-free 5 years later was 77.4% (95% CI, 68.4%-86.4%). Serious stent-related adverse events occurred in 27 of 118 patients (22.9%); all resolved with medical therapy or repeated endoscopy. Multivariate analysis identified severe CP (hazard ratio, 2.4; 95% CI, 1.0-5.6; P = .046) and longer stricture length (hazard ratio, 1.2; 95% CI, 1.0-1.4; P = .022) as predictors of stricture recurrence. CONCLUSION: In patients with symptomatic BBSs secondary to CP, 5 years after placement of a single FCSEMS intended for 10 to 12 months indwell, more than 60% remained asymptomatic and stent-free with an acceptable safety profile. Temporary placement of a single FCSEMS may be considered as first-line treatment for patients with CP and BBSs. (Clinical trial registration number: NCT01014390.).

- Abstract
Item does not contain fulltext, BACKGROUND: Standard endoscopic treatment might fail to treat biliary stone disease. Here, we investigated the efficacy and safety of recently introduced digital single-operator video cholangioscopy (SOVC) for the treatment of difficult biliary stones. METHODS: Digital SOVC procedures, performed in two tertiary referral centers between 2015 and 2018, were retrospectively analyzed. Only patients with a previous failure of endoscopic standard treatment and a SOVC-based biliary stone treatment using electrohydraulic lithotripsy (EHL) or laser lithotripsy (LL) were included. The primary endpoint was to evaluate the stone removal rate per procedure and per patient. RESULTS: In total, 75 examinations with a digital SOVC-assisted biliary stone treatment, performed in 60 patients, were identified. Biliary stones were mainly located extrahepatic (64%) and less frequently intrahepatic (36%). The median stone size was 20 mm (interquartile range [IQR]: 10-25 mm) and the median stone number was 1 (IQR: 1-2). Digital SOVC-based treatment of biliary stone disease was successful in 95% of patients and 15% needed at least two treatment sessions. Evaluated per procedure, a complete stone removal was accomplished in 67% of all examinations (including initial and repeated procedures), while an incomplete stone removal was observed in 33% of cases. The per procedure analyzes revealed that the success rates for a complete stone removal were similar between LL and EHL (66% vs. 68%; p = 0.87). Complications, such as postinterventional cholangitis and pancreatitis occurred in 16% of examinations; however, except from one case, all were mild or moderate and no procedure-associated mortality occurred. CONCLUSIONS: Digital SOVC-assisted biliary stone treatment is highly effective even in cases with difficult biliary stones and might be considered the new standard of care for these patients. Furthermore, mild up to moderate complications were intermittently observed which might document the com

- Abstract
Contains fulltext : 229384.pdf (publisher's version ) (Open Access), Biliary diseases are common, but clinical symptoms are often unspecific and direct access and visualization of the biliopancreatic system for diagnostic purpose is difficult. In the last decades endoscopic ultrasound (EUS) has become a primary method in the gastrointestinal tract. It significantly changed the role of endoscopy in diagnostic imaging in the gastrointestinal tract and adjacent organs. EUS has become an effective diagnostic tool in biliary stone disease as well as in the diagnosis of indeterminate biliary strictures. Furthermore, an EUS-directed transmural approach emerged as a safe and effective alternative to ERCP in patients requiring biliary drainage, in particular as a backup method if standard ERCP-approach fails. Development of new techniques, specific accessories and stents during the last decade led to an enormous step forward in terms of efficacy and safety of an EUS-directed approach. In the current article technical and clinical aspects of EUS-guided diagnostic and therapeutic approaches in different clinical indications will be discussed together with a review of the available data.

On an intention-to-treat basis, the 5-year probability of remaining stent-free after FCSEMS removal or observation of CDM was 48.9% (95% confidence interval [CI], 33.2%-64.7%) among all patients and 60.9% (95% CI, 43.6%-78.2%) among 31 patients with over 4 months of FCSEMS indwell time. In 28 patients with stricture resolution at FCSEMS removal or observed CDM (median, 5.0 months indwell time), the 5-year probability of no stricture recurrence was 72.6% (95% CI, 55.3%-90%). Sixteen patients (39%) had at least 1 related SAE, most commonly cholangitis (n = 10). Conclusions: By 5 years after temporary FCSEMS treatment of post-OLT BBS, approximately half of all patients remained stent-free on an intention-to-treat basis. Stent-related SAEs (especially cholangitis) were common. FCSEMS placement is a viable long-term treatment option for patients with post-OLT BBS. (Clinical trial registration number: NCT01014390.)

Background and Aim: Pancreatic plastic stents (PPS) can reduce the risk of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP). Prospective multicenter documentation of PEP rate after PPS placement is scarce. A new 4-Fr stent designed to be deployed over a 0.035-inch guidewire was used to assess the effectiveness of PEP prophylaxis. Methods: High-PEP-risk patients received a 4-Fr PPS for primary or secondary prophylaxis at seven centers in four countries. Patients were followed until spontaneous PPS migration, endoscopic stent removal, or for 4 months, whichever came first. Main outcome was PEP rate. Results: One hundred six (106) patients received PPS for PEP prophylaxis [61 (58%) primary, 45 (42%) secondary prophylaxis]. Median age was 54 years. Eighty-one (76%) PPS were placed using a 0.035-inch guidewire. By investigator choice 99 (93%) stents were single pigtail. Median stent length was 8 cm (range 3–12 cm). Technical success achieved in 100% of cases. Two patients in the primary prophylaxis group (3%, 95% CI 0.4–11%) experienced mild/moderate PEP. Seventy-eight PPS available for analysis underwent spontaneous migration after a median of 29 days. There were no reports of stent-induced ductal trauma. Post-hoc analysis of migration rate by PPS length showed no statistically significant trend. Conclusions: Among high-risk patients in the primary prophylaxis group, observed rates of PEP are low (3%, 95% CI 0.4– 11%) with the use of prophylactic 4-Fr pancreatic duct stents compatible with a 0.035-inch guidewire. This low rate is not unequivocally due to the prophylactic stent.

Contains fulltext : 215282.pdf (publisher's version ) (Closed access), BACKGROUND & AIMS: Epidemiology studies of circulating concentrations of 25 hydroxy vitamin D (25(OH)D) and risk of esophageal adenocarcinoma (EAC) have produced conflicting results. We conducted a Mendelian randomization study to determine the associations between circulating concentrations of 25(OH)D and risks of EAC and its precursor, Barrett's esophagus (BE). METHODS: We conducted a Mendelian randomization study using a 2-sample (summary data) approach. Six single-nucleotide polymorphisms (SNPs; rs3755967, rs10741657, rs12785878, rs10745742, rs8018720, and rs17216707) associated with circulating concentrations of 25(OH)D were used as instrumental variables. We collected data from 6167 patients with BE, 4112 patients with EAC, and 17,159 individuals without BE or EAC (controls) participating in the Barrett's and Esophageal Adenocarcinoma Consortium, as well as studies from Bonn, Germany, and Cambridge and Oxford, United Kingdom. Analyses were performed separately for BE and EAC. RESULTS: Overall, we found no evidence for an association between genetically estimated 25(OH)D concentration and risk of BE or EAC. The odds ratio per 20 nmol/L increase in genetically estimated 25(OH)D concentration for BE risk estimated by combining the individual SNP association using inverse variance weighting was 1.21 (95% CI, 0.77-1.92; P = .41). The odds ratio for EAC risk, estimated by combining the individual SNP association using inverse variance weighting, was 0.68 (95% CI, 0.39-1.19; P = .18). CONCLUSIONS: In a Mendelian randomization study, we found that low genetically estimated 25(OH)D concentrations were not associated with risk of BE or EAC.

- Abstract
Item does not contain fulltext, INTRODUCTION: Treatment of chronic calcifying pancreatitis is challenging and requires an interdisciplinary approach including endoscopist, surgeon and radiologist. With advances in endoscopic technology therapeutic interventions in the pancreatic duct became available. Extracorporeal shock wave lithotripsy (ESWL) is still recommended to be first line treatment, hence peroral pancreatoscopy- (POP) -guided intracorporal lithotripsy is a promising supplement in endoscopic therapy especially if ESWL is unsuccessful or not available. EVIDENCE AQUISITION: Evidence from published trials, abstracts and case reports on direct pancreatoscopic treatment of main pancreatic duct (MPD) stones was reviewed with focus on efficiency and safety of available technologies, endoscopes and lithotripsy devices. A systematic Medline and Cochrane Database search for relevant studies was performed. EVIDENCE SYNTHESIS: Seventeen relevant publications meeting the inclusion criteria have been identified (two prospective series, seven retrospective trials, six case reports, two abstracts, for a total of 225 patients). Successful ductal clearance for POP-guided treatment was reported between 37.5% and 100%. Clinical success was reported between 74% and 100%. Adverse event (AE) rate for POP-guided therapy is reported with 0-30%. There is no reported mortality following POP treatment. Three ongoing trials found to be registered. CONCLUSIONS: POP-guided lithotripsy seems to be a promising alternative in a very selected patient cohort. Good powered randomized controlled trials are needed to prove efficiency and safety of the new technique also for large numbers of patients before it can be recommended as general practice. The focus of future studies should not only be on technical success, but also clinical success and patient-reported outcomes (quality of life).
