RESUMO
BACKGROUND: Hepaticogastrostomy drainage through endoscopic ultrasound (EUS-HGS) has emerged in the 2010s as a new technique for biliary decompression in cases of endoscopic retrograde cholangiopancreatography (ERCP) failure for malignant biliary obstruction (MBO). Substantial technical and procedural progress in performing EUS-HGS has been achieved, allowing high technical and clinical success and an acceptable risk of adverse events in studies mainly focusing on short-term outcomes. However, the long-term effects of EUS-HGS and the risk of recurrent biliary obstruction (RBO) have not been fully evaluated. OBJECTIVES: To evaluate the long-term effects of EUS-HGS and the risk of RBO. METHODS: Data from 211 patients undergoing technically successful EUS-HGS in three academic centers were retrospectively collected. Clinical success, adverse events, RBO, and reinterventions were evaluated. RESULTS: In total, 198 patients underwent technically successful EUS-HGS for MBO. The median overall survival was 144 days [108, 2011] after the procedure. Mean patient age was 69.39 (12.91) years. The cause of MBO was pancreatic cancer (n = 98, 49.5%) followed by cholangiocarcinoma (n = 29, 14.6%). The location of MBO was distal in 27.6% of cases and proximal in 68.4%. Adverse events were observed during the follow-up in 65 patients (33%). On multivariate analysis, the use of partially covered self-expandable metal stents (PCSEMS) was associated with a lower risk of RBO (HR = 0.47 [0.24-0.95], p = 0.034). Additionally, patients with distal stenoses had a trend toward better stent patency (HR = 0.06[0-0.77], p = 0.031). RBO developed in 38 cases (19.1%) mainly due tumor ingrowth (36.8%) with a high success rate of endoscopic management. CONCLUSIONS: While RBO occurred in a notable proportion of patients, the primary cause of mortality was progression of the underlying malignancy rather than stent dysfunction. The efficiency of stents, particularly PCSEMS, and the high success rate of endoscopic management for RBO underscore the effectiveness and reliability of these treatments in managing biliary complications.
RESUMO
INTRODUCTION: This document is a summary of the French intergroup guidelines of the management of biliary tract cancers (BTC) (intrahepatic, perihilar and distal cholangiocarcinomas, and gallbladder carcinomas) published in September 2023, available on the website of the French Society of Gastroenterology (SNFGE) (www.tncd.org). METHODS: This collaborative work was conducted under the auspices of French medical and surgical societies involved in the management of BTC. Recommendations were graded in three categories (A, B and C) according to the level of scientific evidence until August 2023. RESULTS: BTC diagnosis and staging is mainly based on enhanced computed tomography, magnetic resonance imaging and (endoscopic) ultrasound-guided biopsy. Treatment strategy depends on BTC subtype and disease stage. Surgery followed by adjuvant capecitabine is recommended for localised disease. No neoadjuvant treatment is validated to date. Cisplatin-gemcitabine chemotherapy combined to the anti-PD-L1 inhibitor durvalumab is the first-line standard of care for advanced disease. Early systematic tumour molecular profiling is recommended to screen for actionable alterations (IDH1 mutations, FGFR2 rearrangements, HER2 amplification, BRAFV600E mutation, MSI/dMMR status, etc.) and guide subsequent lines of treatment. In the absence of actionable alterations, FOLFOX chemotherapy is the only second-line standard-of-care. No third-line chemotherapy standard is validated to date. CONCLUSION: These guidelines are intended to provide a personalised therapeutic strategy for daily clinical practice. Each individual BTC case should be discussed by a multidisciplinary team.

BACKGROUND AND AIMS: Endoscopic resection is standard treatment for adenomatous colorectal lesions. Depending on lesion morphology and resection technique, recurrence can occur. Scarred adenomas are challenging to resect and may require surgical management. This study evaluated the safety and effectiveness of an endoscopic powered resection (EPR) system for scarred adenomatous colorectal lesions. METHODS: This single-arm, prospective, multicenter study was conducted from January 2018 to January 2021 at 12 sites. Patients with persistent flat or sessile colorectal lesions were enrolled. Primary end points were technical success (the ability of the device to resect the lesion[s] without use of other resection devices without device-related serious adverse events [AEs]) and safety (the occurrence of AEs through 90 days). Secondary end points included endoscopic confirmation of resection completeness, occurrence of colon stenosis, disease persistence, and diagnostic value of resected specimens. RESULTS: Sixty-five patients were in the intention-to-treat/safety analysis population. Primary analysis was performed on 45 per-protocol (PP) patients with 48 lesions. All PP patients were solely treated by using the EPR device. Technical success was achieved in 44 (98%) patients. Three (5%) serious AEs occurred: 2 delayed self-limited bleeds and 1 perforation. Nonserious AEs included 4 (6%) cases of mild intraprocedural bleeding. Completeness of resection and histopathologic diagnosis of tissue specimens were achieved in all patients. Twenty-one (46.7%) patients had disease persistence after the first treatment, and there was no colon stenosis. CONCLUSIONS: EPR is safe and effective for benign, persistent, large (>20 mm), scarred colorectal adenomas and should be considered as an alternative treatment in lieu of surgery. A persistence rate of 46.7% indicates that >1 treatment is necessary for effective endoscopic treatment. (Clinical trial registration number: NCT04203667.).
RESUMO
Background and study aims The costs of reusable endoscope reprocessing have been evaluated, yet external validity of the findings remains challenging. The aim of this study was to assess the costs of purchase, maintenance, microbiological control, and reprocessing of a reusable duodenoscope per endoscopic retrograde cholangiopancreatography (ERCP) in France. Study findings exclude the costs of infection, downtime due to breakdown, reprocessing single-use material disposal, and device disposal, all of which should also be considered. Materials and methods The study encompassed both observational and theoretical approaches. Observational data were collected in four hospitals, from December 2019 to December 2020, with an ad hoc survey, based on 2016 and 2018 national guidelines for duodenoscope reprocessing. Costs were modeled, using the same guidelines, assuming a mean workload of 223 ERCP/duodenoscope/year. Results The mean observed cost of purchase, maintenance, microbiological control, reprocessing (human resources and consumables), and overhead (additional 35%) with a reusable duodenoscope was 80.23 (standard deviation 3.77) per ERCP. The corresponding mean theoretical cost was 182.71 for manual reprocessing without endoscope drying cabinet (EDC), 191.36 for manual reprocessing with EDC, 235.25 for automated endoscope reprocessing (AER) without EDC, and 253.62 for AER with EDC. Conclusions Because procedures, equipment, volume activity, number of duodenoscopes, human resources, and internal work organizations are hospital-dependent, observed costs varied between hospitals. Theoretical costs were higher than observed costs, showing that the theoretical approach is not sufficient. Hypotheses to explain the difference between the two approaches include failing to measure some costs in the survey and challenges in guideline implementation.
RESUMO
OBJECTIVES: A new short device for percutaneous endoscopic cholangioscopy was recently developed. However, feasibility and safety has not yet been evaluated. The aim of this study was to assess clinical success, technical success, and adverse events (AEs). METHODS: This observational multicenter retrospective study included all patients who underwent percutaneous cholangioscopy using a short cholangioscope between 2020 and 2022. The clinical success, defined as the complete duct clearance or obtaining at least one cholangioscopy-guided biopsy, was assessed. The histopathological accuracy, technical success, and the AE rate were also evaluated. RESULTS: Fifty-one patients (60 ± 15 years, 45.1% male) were included. The majority of patients had altered anatomy (n = 40, 78.4%), and biliary stones (n = 34, 66.7%) was the commonest indication. The technique was predominantly wire-guided (n = 44, 86.3%) through a percutaneous sheath (n = 36, 70.6%) following a median interval of 8.5 days from percutaneous drainage. Cholangioscopy-guided electrohydraulic lithotripsy was performed in 29 cases (56.9%), combined with a retrieval basket in eight cases (27.6%). The clinical success was 96.6%, requiring a median of one session (range 1-3). Seventeen patients (33.3%) underwent cholangioscopy-guided biopsies. There were four (7.8%) cholangioscopy-related AEs (cholangitis and peritonitis). Overall, the technical success and AE rates were 100% and 19.6%, respectively, in a median follow-up of 7 months. CONCLUSION: Percutaneous endoscopic cholangioscopy with a new short device is effective and safe, requiring a low number of sessions to achieve duct clearance or accurate histopathological diagnosis.
RESUMO
INTRODUCTION: Ampullary neuroendocrine neoplasia (NEN) is rare and evidence regarding their management is scarce. This study aimed to describe clinicopathological features, management, and prognosis of ampullary NEN according to their endoscopic or surgical management. METHODS: From a multi-institutional international database, patients treated with either endoscopic papillectomy (EP), transduodenal surgical ampullectomy (TSA), or pancreaticoduodenectomy (PD) for ampullary NEN were included. Clinical features, post-procedure complications, and recurrences were assessed. RESULTS: 65 patients were included, 20 (30.8%) treated with EP, 19 (29.2%) with TSA, and 26 (40%) with PD. Patients were mostly asymptomatic (n = 46; 70.8%). Median tumor size was 17 mm (12-22), tumors were mostly grade 1 (70.8%) and pT2 (55.4%). Two (10%) EP resulted in severe American Society for Gastrointestinal Enterology (ASGE) adverse post-procedure complications and 10 (50%) were R0. Clavien 3-5 complications did not occur after TSA and in 4, including 1 postoperative death (15.4%) of patients after PD, with 17 (89.5%) and 26 R0 resection (100%), respectively. The pN1/2 rate was 51.9% (n = 14) after PD. Tumor size larger than 1 cm (i.e., pT stage >1) was a predictor for R1 resection (p < 0.001). Three-year overall survival and disease-free survival after EP, TSA, and PD were 92%, 68%, 92% and 92%, 85%, 73%, respectively. CONCLUSION: Management of ampullary NEN is challenging. EP should not be performed in lesions larger than 1 cm or with a endoscopic ultrasonography T stage beyond T1. Local resection by TSA seems safe and feasible for lesions without nodal involvement. PD should be preferred for larger ampullary NEN at risk of nodal metastasis.

BACKGROUND: It is unclear whether preoperative biliary drainage (PBD) by endoscopic retrograde cholangiopancreatography (ERCP) is equivalent to electrocautery-enhanced lumen-apposing metal stent (ECE-LAMS) before pancreatoduodenectomy (PD). METHODS: Patients who underwent PBD for distal malignant biliary obstruction (DMBO) followed by PD were retrospectively included in nine expert centers between 2015 and 2022. ERCP or endoscopic ultrasound-guided choledochoduodenostomy with ECE-LAMS were performed. In intent-to-treat analysis, patients drained with ECE-LAMS were considered the study group (first-LAMS group) and those drained with conventional transpapillary stent the control group (first-cannulation group). The rates of technical success, clinical success, drainage-related complications, surgical complications, and oncological outcomes were analyzed. RESULTS: Among 156 patients, 128 underwent ERCP and 28 ECE-LAMS in first intent. The technical and clinical success rates were 83.5% and 70.2% in the first-cannulation group versus 100% and 89.3% in the first-LAMS group (p = 0.02 and p = 0.05, respectively). The overall complication rate over the entire patient journey was 93.7% in first-cannulation group versus 92.0% in first-LAMS group (p = 0.04). The overall endoscopic complication rate was 30.5% in first-cannulation group versus 17.9% in first-LAMS group (p = 0.25). The overall complication rate after PD was higher in the first-cannulation group than in the first-LAMS group (92.2% versus 75.0%, p = 0.016). Overall survival and progression-free survival did not differ between the groups. CONCLUSIONS: PBD with ECE-LAMS is easier to deploy and more efficient than ERCP in patients with DMBO. It is associated with less surgical complications after pancreatoduodenectomy without compromising the oncological outcome.

Background and study aims Esophageal stricture is the most frequent adverse event after endoscopic resection for early esophageal neoplasia. Currently available treatments for the prevention of esophageal stricture are poorly effective and associated with major adverse events. Our aim was to identify transcripts specifically overexpressed or repressed in patients who have developed a post-endoscopic esophageal stricture, as potential targets for stricture prevention. Patients and methods We conducted a prospective single-center study in a tertiary endoscopy center. Patients scheduled for an endoscopic resection and considered at risk of esophageal stricture were offered inclusion in the study. The healthy mucosa and resection bed were biopsied on Days 0, 14, and 90. A transcriptomic analysis by microarray was performed, and the differences in transcriptomic profile compared between patients with and without esophageal strictures. Results Eight patients, four with esophageal stricture and four without, were analyzed. The mean ± SD circumferential extension of the mucosal defect was 85â±â11â%. The transcriptomic analysis in the resection bed at day 14 found an activation of the interleukin (IL)-1 group (Z scoreâ=â2.159, P â=â0.0137), while interferon-gamma (INFγ) and NUPR1 were inhibited (Z scoreâ=â-2.375, P â=â0.0022 and Z scoreâ=â-2.333, P â=â0.00131) in the stricture group.âNone of the activated or inhibited transcripts were still significantly so in any of the groups on Day 90. Conclusions Our data suggest that IL-1 inhibition or INFγ supplementation could constitute promising targets for post-endoscopic esophageal stricture prevention.
RESUMO
BACKGROUND: Acute cholangitis (AC) is an infection of the biliary tract secondary to biliary obstruction requiring biliary drainage through endoscopic retrograde cholangiopancreatography. This study aims to compare the outcome between the early and delayed ERCP in patients with severe AC. METHODS: Patient with severe AC due to choledocholithiasis admitted to intensive care unit were included. Early ERCP was defined was as ERCP performed within 24 h following hospital admission. Propensity-score matching was used to reduce the imbalance between groups. The primary outcome was 30-day mortality. Secondary outcomes included length of hospital and ICU stay, onset or persistent organ failure. RESULTS: The delayed ERCP group had a higher mortality rate at 30 days (45,5 versus 13%, <0.001) and at 1 year (59,7% versus 15,6%, p <0.001). Delayed ERCP had also a higher rate of respiratory adverse events (54,5 versus 27,8%, p = 0,002), longer ICU (7.41 versus 4.61, p = 0,004) and hospital (11,88 versus 9,22, p = 0,042) length of stay. Predictors of delayed ERCP were cardiac arrythmias, liver disease, creatinine value and white blood cell count at baseline. CONCLUSIONS: Delays in ERCP for patients with severe AC appear to be associated with higher mortality rate and prolonged ICU and hospital stays.

RESUMO
INTRODUCTION: The coronavirus disease 2019 (COVID-19) pandemic has had a dramatic impact on cancer diagnosis and care pathways. Here, we assessed the mid-term impact of the COVID-19 pandemic on older adults with cancer before, during and after the lockdown period in 2020. MATERIALS AND METHODS: We performed a retrospective, observational, multicentre cohort study of prospectively collected electronic health records. All adults aged 65 or over and having been newly treated for a digestive system cancer in our institution between January 2018 until August 2020 were enrolled. RESULTS: Data on 7,881 patients were analyzed. Although the overall 10-month mortality rate was similar in 2020 vs. 2018-2019, the mortality rate among for patients newly treated in the 2020 post-lockdown period was (after four months of follow-up) significantly higher. A subgroup analysis revealed higher mortality rates for (i) patients diagnosed in the emergency department during the pre-lockdown period, (ii) patients with small intestine cancer newly treated during the post-lockdown period, and (iii) patients having undergone surgery with curative intent during the post-lockdown period. However, when considering individuals newly treated during the lockdown period, we observed lower mortality rates for (i) patients aged 80 and over, (ii) patients with a biliary or pancreatic cancer, and (iii) patients diagnosed in the emergency department. DISCUSSION: There was no overall increase in mortality among patients newly treated in 2020 vs. 2018-2019. Longer follow-up is needed to assess the consequences of the pandemic. A subgroup analysis revealed significant intergroup differences in mortality.

Background Biliary tract emergencies are managed with endoscopic retrograde cholangiopancreatography (ERCP) using duodenoscopes, which are reusable devices that require high-level disinfection to minimize risk of cross-contamination. Recent reports about newly developed single-use duodenoscopes (SUDs) suggest equivalent performance with reusable duodenoscopes, but the effectiveness of SUDs in emergency ERCP has not yet been studied. Patients and methods We conducted a prospective case series of emergency ERCP procedures using SUDs (EXALT model D-Boston Scientific, United States) in a real-life, tertiary care setting without any possibility of using a back-up reusable duodenoscope. Results Twenty-one emergent ERCPs (acute cholangitis 48%, severe jaundice 38â%, others 14â%) were performed in 19 patients (mean age 49.5±15 years). Almost all procedures (20 of 21; 95â%) were technically and clinically successful, whereas selective cannulation failed in one case. Among the successful ERCPs, five (24â%) were achieved by a novice operator. The image was often considered skewed toward yellow tones (48â%), whereas stiffness and pushability for stent insertion were found suboptimal in 5â% of the procedures, without any impact on procedure success. Conclusions SUDs are effective and appropriate devices for emergent situations in real life even in non-expert hands and even if a regular duodenoscope is unavailable as a backup.
RESUMO
Endoscopic mucosal resection (EMR) is the recommended treatment for superficial non-ampullary duodenal epithelial tumors larger than 6 mm. This endoscopic technique carries a high risk of adverse events. Our aim was to identify the risk factors for adverse events following EMR for non-ampullary duodenal adenomatous lesions. We retrospectively analyzed a prospectively collected database of consecutive endoscopic resections for duodenal lesions at a tertiary referral center for therapeutic endoscopy. We analyzed patients with non-ampullary duodenal adenomatous lesions ≥ 10 mm resected by EMR, and searched for factors associated with adverse events after EMR. 167 duodenal adenomatous lesions, with a median size of 25 (25-40) mm, were resected by EMR between January 2015 and December 2020. Adverse events occurred in 37/167 (22.2%) after endoscopic resection, with 29/167 (17.4%) delayed bleeding, 4/167 (2.4%) immediate perforation and 4/167 (2.4%) delayed perforation. In logistic regression, the size of the lesion was the only associated risk factor of adverse events (OR = 2.81, 95% CI [1.27; 6.47], p = 0.012). Adverse events increased mean hospitalization time (7.7 ± 9 vs. 1.9 ± 1 days, p < 0.01). None of the currently recommended preventive methods, particularly clips, affected the adverse event rate. EMR of centimetric and supracentimetric duodenal adenomatous lesions carries a high risk of adverse events, increasing with the size of the lesion and with no benefit from any preventive method. These results suggest that these procedures should be performed in expert centers, and underline the need for novel endoscopic tools to limit the rate of adverse events.

RESUMO
Pancreatic ductal adenocarcinoma (PDAC) is expected to become the second leading cause of death from cancer by 2030. Despite intensive research in the field of therapeutics, the 5-year overall survival is approximately 8%, with only 20% of patients eligible for surgery at the time of diagnosis. The tumoral microenvironment (TME) of the PDAC is one of the main causes for resistance to antitumoral treatments due to the presence of tumor vasculature, stroma, and a modified immune response. The TME of PDAC is characterized by high stiffness due to fibrosis, with hypo microvascular perfusion, along with an immunosuppressive environment that constitutes a barrier to effective antitumoral treatment. While systemic therapies often produce severe side effects that can alter patients' quality of life, locoregional therapies have gained attention since their action is localized to the pancreas and can thus alleviate some of the barriers to effective antitumoral treatment due to their physical effects. Local hyperthermia using radiofrequency ablation and radiation therapy - most commonly using a local high single dose - are the two main modalities holding promise for clinical efficacy. Recently, irreversible electroporation and focused ultrasound-derived cavitation have gained increasing attention. To date, most of the data are limited to preclinical studies, but ongoing clinical trials may help better define the role of these locoregional therapies in the management of PDAC patients.

OBJECTIVES: Endoscopic ultrasound-guided digestive anastomosis (EUS-A) is a new alternative under evaluation in patients presenting with afferent limb syndrome (ALS) after Whipple surgery. The aim of the present study is to analyze the safety and effectiveness of EUS-A in ALS. METHODS: This is an observational multicenter study. All patients ≥18 years old with previous Whipple surgery presenting with ALS who underwent an EUS-A using a lumen-apposing metal stent (LAMS) between 2015 and 2021 were included. The primary outcome was clinical success, defined as resolution of the ALS or ALS-related cholangitis. Furthermore, technical success, adverse event rate, and mortality were evaluated. RESULTS: Forty-five patients (mean age: 65.5 ± 10.2 years; 44.4% male) were included. The most common underlying disease was pancreatic cancer (68.9%). EUS-A was performed at a median of 6 weeks after local tumor recurrence. The most common approach used was the direct/freehand technique (66.7%). Technical success was achieved in 95.6%, with no differences between large (≥15 mm) and small LAMS (97.4% vs. 100%, P = 0.664). Clinical success was retained in 91.1% of patients. A complementary treatment by dilation of the stent followed by endoscopic retrograde cholangiopancreatography through the LAMS was performed in three cases (6.7%). There were six recurrent episodes of cholangitis (14.6%) and two procedure-related adverse events (4.4%) after a median follow-up of 4 months. Twenty-six patients (57.8%) died during the follow-up due to disease progression. CONCLUSION: EUS-A is a safe and effective technique in the treatment of malignant ALS, achieving high clinical success with an acceptable recurrence rate.
