RESUMO

OBJECTIVE: To describe the long-term consequences of necrotising pancreatitis, including complications, the need for interventions and the quality of life. DESIGN: Long-term follow-up of a prospective multicentre cohort of 373 necrotising pancreatitis patients (2005-2008) was performed. Patients were prospectively evaluated and received questionnaires. Readmissions (ie, for recurrent or chronic pancreatitis), interventions, pancreatic insufficiency and quality of life were compared between initial treatment groups: conservative, endoscopic/percutaneous drainage alone and necrosectomy. Associations of patient and disease characteristics during index admission with outcomes during follow-up were assessed. RESULTS: During a median follow-up of 13.5 years (range 12-15.5 years), 97/373 patients (26%) were readmitted for recurrent pancreatitis. Endoscopic or percutaneous drainage was performed in 47/373 patients (13%), of whom 21/47 patients (45%) were initially treated conservatively. Pancreatic necrosectomy or pancreatic surgery was performed in 31/373 patients (8%), without differences between treatment groups. Endocrine insufficiency (126/373 patients; 34%) and exocrine insufficiency (90/373 patients; 38%), developed less often following conservative treatment (p<0.001 and p=0.016, respectively). Quality of life scores did not differ between groups. Pancreatic gland necrosis >50% during initial admission was associated with percutaneous/endoscopic drainage (OR 4.3 (95% CI 1.5 to 12.2)), pancreatic surgery (OR 3.2 (95% CI 1.1 to 9.5) and development of endocrine insufficiency (OR13.1 (95% CI 5.3 to 32.0) and exocrine insufficiency (OR6.1 (95% CI 2.4 to 15.5) during follow-up. CONCLUSION: Acute necrotising pancreatitis carries a substantial disease burden during long-term follow-up in terms of recurrent disease, the necessity for interventions and development of pancreatic insufficiency, even when treated conservatively during the index admission. Extensive (>50%) pancreatic parenchymal necrosis seems to be an important predictor of interventions and complications during follow-up.

RESUMO

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) with fully covered self-expandable metal stent (FCSEMS) placement is the preferred approach for biliary drainage in patients with suspected distal malignant biliary obstruction (MBO). However, FCSEMS placement is associated with a high risk of post-ERCP pancreatitis (PEP). Endoscopic sphincterotomy prior to FCSEMS placement may reduce PEP risk. OBJECTIVE: To compare endoscopic sphincterotomy to no sphincterotomy prior to FCSEMS placement. DESIGN: This multicentre, randomised, superiority trial was conducted in 17 hospitals and included patients with suspected distal MBO. Patients were randomised during ERCP to receive either endoscopic sphincterotomy (sphincterotomy group) or no sphincterotomy (control group) prior to FCSEMS placement. The primary outcome was PEP within 30 days. Secondary outcomes included procedure-related complications and 30-day mortality. An interim analysis was performed after 50% of patients (n=259) had completed follow-up. RESULTS: Between May 2016 and June 2023, 297 patients were included in the intention-to-treat analysis, with 156 in the sphincterotomy group and 141 in the control group. After the interim analysis, the study was terminated prematurely due to futility. PEP did not differ between groups, occurring in 26 patients (17%) in the sphincterotomy group compared with 30 patients (21%) in the control group (relative risk 0.78, 95% CI 0.49 to 1.26, p=0.37). There were no significant differences in bleeding, perforation, cholangitis, cholecystitis or 30-day mortality. CONCLUSION: This trial found that endoscopic sphincterotomy was not superior to no sphincterotomy in reducing PEP in patients with distal MBO. Therefore, there was insufficient evidence to recommend routine endoscopic sphincterotomy prior to FCEMS placement. TRIAL REGISTRATION NUMBER: NL5130.

RESUMO

BACKGROUND AND AIMS: Biliary drainage by endoscopic retrograde cholangiography (ERCP) in patients with malignant distal bile duct obstruction (MBO) is frequently associated with complications, such as pancreatitis, hampering patient outcome. EUS-guided choledochoduodenostomy (EUS-CDS) with a lumen-apposing metal stent (LAMS) is a promising alternative in patients with MBO but is associated with a worrisome risk of stent dysfunction. Placement of a fully covered self-expandable metal stent (FCSEMS) through the LAMS, thereby changing the axis of biliary drainage towards the descending duodenum, may decrease the risk of stent dysfunction while maintaining high technical success and low adverse event rates. METHODS: Prospective single center pilot study in patients with a pathology confirmed MBO without gastric-outlet obstruction. Primary outcome was stent dysfunction, defined as recurrent jaundice after initial clinical success, ongoing jaundice in combination with persistent bile duct dilatation, or cholangitis. The study was registered in clinicaltrials.gov (registry number NCT05595122). RESULTS: Overall, 27 consecutive patients eligible for EUS-CDS were enrolled. The placement of a LAMS was successful in 24/27 patients (89%), and placement of FCSEMS through the LAMS was successful in 20/24 (83%), in the remaining 4 patients a coaxial double-pigtail plastic stent was placed. In 2 of these 20 patients there was persistent jaundice requiring stent revision (10%), leading to a clinical success rate of 90%. No patients developed stent dysfunction after initial clinical success. CONCLUSIONS: This study showed a stent dysfunction rate of 10% following technically successful EUS-CDS with placement of a FCSEMS through the LAMS. Improving the design of LAMS may further reduce the rate of stent dysfunction.

RESUMO

BACKGROUND: This study aimed to assess the safety and feasibility of endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) using a lumen-apposing metal stent (LAMS) as a primary drainage strategy in patients with distal malignant biliary obstruction (MBO). METHODS: A prospective, single-center, pilot study was conducted in patients with pathology-confirmed MBO without gastric outlet obstruction. The primary outcome was technical success. Secondary outcomes included clinical success, adverse events (AEs), and reinterventions. The study was registered in the Netherlands Trial Registry (registry number NL9757). RESULTS: 22 patients were enrolled (median age 69.5 years [interquartile range 64-75.3]). Technical success was achieved in 20/22 patients (91 %). AEs occurred in one patient, namely perforation following inadequate stent deployment (5 %), which was treated in the same procedure. Clinical success was achieved in 19/22 patients (86 %). Stent dysfunction was observed in 11/20 patients (55 %) after technically successful EUS-CDS: two patients were treated conservatively and nine patients underwent reintervention(s). One patient died within ≤ 30 days due to fulminant disease progression. CONCLUSIONS: The results confirmed the safety and feasibility of EUS-CDS using LAMS as a primary drainage strategy. The high incidence of stent dysfunction should be improved before EUS-CDS with LAMS can be seen as a valid alternative to endoscopic retrograde cholangiopancreatography.

RESUMO

Endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) with lumen apposing metal stent is emerging both as a rescue strategy and a primary treatment for distal malignant biliary obstruction. The large-scale diffusion of the procedure and improved overall survival of patients with pancreatobiliary neoplasms is resulting in a growing population of long-term EUS-CDS lumen apposing metal stent carriers. Recent studies have reported a need for reintervention during follow-up as high as 55%, and the Leuven-Amsterdam-Milan Study Group classification has been developed, identifying five mechanisms of stent dysfunction and 11 possible rescue strategies aimed at restoring biliary drainage. This illustrated technical review aims to further dissect the recent classification through a comprehensive analysis of nine illustrative cases, offering insights into the pathophysiology underlying dysfunction and clinical reasoning behind rescue interventions, as well as technical considerations and practical tips and tricks. By exploring mechanisms of dysfunction, this review also assists clinicians in selecting the ideal candidates for EUS-CDS while identifying patients deemed high risk for dysfunction or clinical failure.

RESUMO

BACKGROUND: Recurrent non-stenotic cholangitis (NSC) is a difficult-to-treat complication after hepaticojejunostomy (HJ) leading to multiple hospital admissions. The optimal treatment strategy is unclear as a systematic review is lacking. METHODS: A systematic review was performed including studies detailing treatment strategies and outcomes for recurrent NSC in patients with a surgical HJ in PubMed, Embase, and Cochrane Library (inception - September 2023). Primary outcome was resolution of NSC as defined by the included studies. RESULTS: Overall, 72 patients with recurrent NSC after HJ were included from seven retrospective studies. The rate of recurrent NSC (specified in five studies) was 4% (46/1143 HJs). Diagnosis of NSC was mostly made after excluding HJ stenosis and assessing bile reflux. Initial treatment consisted of short-course antibiotics for all patients. Second step treatment consisted of prolonged antibiotic therapy (n = 10, 13.8%). Third step treatment consisted of surgery (n = 9, n = 12.5%); mostly lengthening of the biliary loop. Together, the overall reported resolution-rate of recurrent NSC was 66.6% (n = 48). CONCLUSION: A 'step-up approach' may be effective in two-thirds of patients with recurrent NSC after HJ, starting with short-course antibiotics, and eventually adding prolonged antibiotic therapy and, ultimately, surgery aimed at preventing intestinal content and food reflux. Prospective studies are needed.

RESUMO

BACKGROUND: Cholangitis is a well-known complication after hepaticojejunostomy (HJ), which is mainly caused by a stenotic anastomosis. However, the rate of cholangitis in patients with a non-stenotic (i.e. patent) HJ is unknown. We aimed to evaluate the incidence and risk factors of recurrent cholangitis in patients with a non-stenotic HJ. METHODS: This single-center retrospective cohort study included all consecutive patients who had undergone hepatobiliary or pancreatic (HPB) surgery requiring HJ (2015-2022). Primary outcome was recurrent non-stenotic cholangitis, risk factors for recurrent non-stenotic cholangitis were identified using logistic regression. RESULTS: Overall, 835 patients with a HJ were included of whom 31/698 (4.4%) patients developed recurrent cholangitis with a non-stenotic HJ during a median follow-up of 34 months (IQR 22-50) and 98/796 (12.3%) patients developed a symptomatic HJ stenosis. These 31 patients experienced 205 cholangitis episodes, median 7.0 (IQR 3.8-8.8) per patient, and 71/205 (34.6%) cholangitis episodes required hospitalization. Male sex (aOR 3.17 (95% CI: 1.34-7.49)) and benign disease (aOR 2.97, 95% CI 1.40-6.33) were identified as risk factors for recurrent cholangitis in non-stenotic HJ in both univariate and multivariable analysis. CONCLUSION: This study shows that 4% of patients developed recurrent cholangitis without an underlying HJ stenosis.

RESUMO

OBJECTIVE: Routine urgent endoscopic retrograde cholangiopancreatography (ERCP) with endoscopic biliary sphincterotomy (ES) does not improve outcome in patients with predicted severe acute biliary pancreatitis. Improved patient selection for ERCP by means of endoscopic ultrasonography (EUS) for stone/sludge detection may challenge these findings. DESIGN: A multicentre, prospective cohort study included patients with predicted severe acute biliary pancreatitis without cholangitis. Patients underwent urgent EUS, followed by ERCP with ES in case of common bile duct stones/sludge, within 24 hours after hospital presentation and within 72 hours after symptom onset. The primary endpoint was a composite of major complications or mortality within 6 months after inclusion. The historical control group was the conservative treatment arm (n=113) of the randomised APEC trial (Acute biliary Pancreatitis: urgent ERCP with sphincterotomy versus conservative treatment, patient inclusion 2013-2017) applying the same study design. RESULTS: Overall, 83 patients underwent urgent EUS at a median of 21 hours (IQR 17-23) after hospital presentation and at a median of 29 hours (IQR 23-41) after start of symptoms. Gallstones/sludge in the bile ducts were detected by EUS in 48/83 patients (58%), all of whom underwent immediate ERCP with ES. The primary endpoint occurred in 34/83 patients (41%) in the urgent EUS-guided ERCP group. This was not different from the 44% rate (50/113 patients) in the historical conservative treatment group (risk ratio (RR) 0.93, 95% CI 0.67 to 1.29; p=0.65). Sensitivity analysis to correct for baseline differences using a logistic regression model also showed no significant beneficial effect of the intervention on the primary outcome (adjusted OR 1.03, 95% CI 0.56 to 1.90, p=0.92). CONCLUSION: In patients with predicted severe acute biliary pancreatitis without cholangitis, urgent EUS-guided ERCP with ES did not reduce the composite endpoint of major complications or mortality, as compared with conservative treatment in a historical control group. TRIAL REGISTRATION NUMBER: ISRCTN15545919.

RESUMO

INTRODUCTION: Necrotizing pancreatitis may result in a disrupted or disconnected pancreatic duct (DPD) with the potential for long-lasting negative impact on a patient's clinical outcome. There is a lack of detailed data on the full clinical spectrum of DPD, which is critical for the development of better diagnostic and treatment strategies. METHODS: We performed a long-term post hoc analysis of a prospectively collected nationwide cohort of 896 patients with necrotizing pancreatitis (2005-2015). The median follow-up after hospital admission was 75 months (P25-P75: 41-151). Clinical outcomes of patients with and without DPD were compared using regression analyses, adjusted for potential confounders. Predictive features for DPD were explored. RESULTS: DPD was confirmed in 243 (27%) of the 896 patients and resulted in worse clinical outcomes during both the patient's initial admission and follow-up. During hospital admission, DPD was associated with an increased rate of new-onset intensive care unit admission (adjusted odds ratio [aOR] 2.52; 95% confidence interval [CI] 1.62-3.93), new-onset organ failure (aOR 2.26; 95% CI 1.45-3.55), infected necrosis (aOR 4.63; 95% CI 2.87-7.64), and pancreatic interventions (aOR 7.55; 95% CI 4.23-13.96). During long-term follow-up, DPD increased the risk of pancreatic intervention (aOR 9.71; 95% CI 5.37-18.30), recurrent pancreatitis (aOR 2.08; 95% CI 1.32-3.29), chronic pancreatitis (aOR 2.73; 95% CI 1.47-5.15), and endocrine pancreatic insufficiency (aOR 1.63; 95% CI 1.05-2.53). Central or subtotal pancreatic necrosis on computed tomography (OR 9.49; 95% CI 6.31-14.29) and a high level of serum C-reactive protein in the first 48 hours after admission (per 10-point increase, OR 1.02; 95% CI 1.00-1.03) were identified as independent predictors for developing DPD. DISCUSSION: At least 1 of every 4 patients with necrotizing pancreatitis experience DPD, which is associated with detrimental, short-term and long-term interventions, and complications. Central and subtotal pancreatic necrosis and high levels of serum C-reactive protein in the first 48 hours are independent predictors for DPD.

RESUMO

BACKGROUND: Cholecystectomy in patients with idiopathic acute pancreatitis (IAP) is controversial. A randomized trial found cholecystectomy to reduce the recurrence rate of IAP but did not include preoperative endoscopic ultrasonography (EUS). As EUS is effective in detecting gallstone disease, cholecystectomy may be indicated only in patients with gallstone disease. This study aimed to determine the diagnostic value of EUS in patients with IAP, and the rate of recurrent pancreatitis in patients in whom EUS could not determine the aetiology (EUS-negative IAP). METHODS: This prospective multicentre cohort study included patients with a first episode of IAP who underwent outpatient EUS. The primary outcome was detection of aetiology by EUS. Secondary outcomes included adverse events after EUS, recurrence of pancreatitis, and quality of life during 1-year follow-up. RESULTS: After screening 957 consecutive patients with acute pancreatitis from 24 centres, 105 patients with IAP were included and underwent EUS. In 34 patients (32 per cent), EUS detected an aetiology: (micro)lithiasis and biliary sludge (23.8 per cent), chronic pancreatitis (6.7 per cent), and neoplasms (2.9 per cent); 2 of the latter patients underwent pancreatoduodenectomy. During 1-year follow-up, the pancreatitis recurrence rate was 17 per cent (12 of 71) among patients with EUS-negative IAP versus 6 per cent (2 of 34) among those with positive EUS. Recurrent pancreatitis was associated with poorer quality of life. CONCLUSION: EUS detected an aetiology in a one-third of patients with a first episode of IAP, requiring mostly cholecystectomy or pancreatoduodenectomy. The role of cholecystectomy in patients with EUS-negative IAP remains uncertain and warrants further study.


Some patients develop acute inflammation of the pancreas without a clear cause. These patients have a high risk of developing more episodes of acute inflammation of the pancreas. Potentially, such inflammation could be caused by tiny gallstones that physicians are not able to detect. If this is true, these patients may also benefit from surgical removal of the gallbladder. However, this is still controversial. Endoscopic ultrasonography is a diagnostic procedure during which a physician looks at the gallbladder and bile ducts in detail via a small ultrasound probe inserted through the mouth. This endoscopic ultrasonography may be able to detect gallstones better than physicians were able to previously. This study tested the value of endoscopic ultrasonography, and the number of patients who developed more episodes of acute inflammation after endoscopic ultrasonography was recorded. Some 106 patients with acute inflammation of the pancreas for the first time without a clear cause participated and were offered endoscopic ultrasonography. The number of times endoscopic ultrasonography found a cause for the acute inflammation was recorded, as well as safety parameters, number of patients who developed more episodes of acute inflammation, and quality of life. After screening 957 patients, 105 ultimately underwent endoscopic ultrasonography. A cause was found in one-third of patients. This was mostly (tiny) gallstones, but chronic inflammation and even tumours were found. These patients were mostly treated surgically for their gallstones and tumours. In the first year after the first acute episode of inflammation, the inflammation came back at least once in almost one in six patients in whom endoscopic ultrasonography did not find a cause. This occurred less in patients in whom a cause was found; the inflammation came back in 1 in 16 of these patients. It was also found that having inflammation coming back negatively affected quality of life. In this study, endoscopic ultrasonography was able to detect a cause in one-third of patients with first-time acute inflammation of the pancreas. In one in four patients, this cause could be treated by a surgical procedure. Whether surgical removal of the gallbladder can be helpful in patients in whom endoscopic ultrasonography is not able to detect an aetiology should be investigated in further studies.

RESUMO

BACKGROUND AND AIMS: Gastric outlet and biliary obstruction are common manifestations of GI malignancies and some benign diseases for which standard treatment would be surgical gastroenterostomy and hepaticojejunostomy (ie, "double bypass"). Therapeutic EUS has allowed for the creation of an EUS-guided double bypass. However, same-session double EUS-guided bypass has only been described in small proof-of-concept series and lacks a comparison with surgical double bypass. METHODS: A retrospective multicenter analysis was performed of all consecutive same-session double EUS-guided bypass procedures performed in 5 academic centers. Surgical comparators were extracted from these centers' databases from the same time interval. Efficacy, safety, hospital stay, nutrition and chemotherapy resumption, long-term patency, and survival were compared. RESULTS: Of 154 identified patients, 53 (34.4%) received treatment with EUS and 101 (65.6%) with surgery. At baseline, patients undergoing EUS exhibited higher American Society of Anesthesiologists scores and a higher median Charlson Comorbidity Index (9.0 [interquartile range {IQR}, 7.0-10.0] vs 7.0 [IQR, 5.0-9.0], P < .001). Technical success (96.2% vs 100%, P = .117) and clinical success rates (90.6% vs 82.2%, P = .234) were similar when comparing EUS and surgery. Overall (11.3% vs 34.7%, P = .002) and severe adverse events (3.8% vs 19.8%, P = .007) occurred more frequently in the surgical group. In the EUS group, median time to oral intake (0 days [IQR, 0-1] vs 6 days [IQR, 3-7], P < .001) and hospital stay (4.0 days [IQR, 3-9] vs 13 days [IQR, 9-22], P < .001) were significantly shorter. CONCLUSIONS: Despite being used in a patient population with more comorbidities, same-session double EUS-guided bypass achieved similar technical and clinical success and was associated with fewer overall and severe adverse events when compared with surgical gastroenterostomy and hepaticojejunostomy.

RESUMO

BACKGROUND: Endoscopic retrograde cholangiopancreatography (ERCP) with biliary brush cytology is commonly used to diagnose malignant pancreatobiliary strictures. This trial compared the sensitivity of two intraductal brush cytology devices. METHODS: A randomized controlled trial in which consecutive patients with suspected malignant, extrahepatic biliary strictures were randomized (1:1) to a dense or conventional brush cytology device. Primary endpoint was sensitivity. Interim analysis was conducted after 50% of the patients completed follow-up. Results were interpreted by a data safety monitoring board. RESULTS: Between June 2016 and June 2021, 64 patients were randomized to the dense (27 patients, 42%) or conventional brush (37 patients, 58%). Malignancy was diagnosed in 60 patients (94%) and benign disease in 4 patients (6%). Diagnoses were confirmed by histopathology in 34 patients (53%), cytopathology in 24 patients (38%), and clinical or radiological follow up in 6 patients (9%). Sensitivity of the dense brush was 50%, compared to 44% for the conventional brush (p = 0·785). DISCUSSION: The results of this randomized controlled trial showed that the sensitivity of a dense brush is not superior to a conventional brush for diagnosing malignant extrahepatic pancreatobiliary strictures. This trial was prematurely ended for reasons of futility. TRIAL REGISTRATION: Netherlands Trial Register number; NTR5458.

RESUMO

OBJECTIVES: Long-term outcomes of endoscopic ultrasound-guided choledochoduodenostomy (EUS-CDS) performed with lumen apposing metal stents (LAMS) have been poorly evaluated in small or retrospective series, leading to an underestimation of LAMS dysfunction. METHODS: All consecutive EUS-CDS performed in three academic referral centers were included in prospectively maintained databases. Technical/clinical success, adverse events (AEs), and dysfunction during follow-up were retrospectively analyzed. Kaplan-Meier analysis was used to estimate dysfunction-free survival (DFS), with Cox proportional hazard regression to evaluate independent predictors of dysfunction. RESULTS: Ninety-three patients were included (male 56%; mean age, 70 years [95% confidence interval (CI) 68-72]; pancreatic cancer 81%, metastatic disease 47%). In 67% of procedures, 6 mm LAMS were used. Technical and clinical success were achieved in 97.8% and 93.4% of patients, respectively, with AEs occurring in 9.7% (78% mild/moderate). Dysfunction occurred in 31.8% of patients after a mean of 166 days (95% CI 91-241), with an estimated 6 month and 12 month DFS of 75% and 52%, respectively; mean DFS of 394 (95% CI 307-482) days. Almost all dysfunctions (96%) were successfully managed by endoscopic reintervention. Duodenal invasion (hazard ratio 2.7 [95% CI 1.1-6.8]) was the only independent predictor of dysfunction. CONCLUSIONS: Endoscopic ultrasound-guided choledochoduodenostomy shows excellent initial efficacy and safety, although stent dysfunctions occurs frequently during long-term follow-up. Almost all stent dysfunctions can be managed successfully by endoscopic reinterventions. We propose a comprehensive classification of the different types of dysfunction that may be encountered and rescue procedures that may be employed under these circumstances. Duodenal invasion seems to increase the risk of developing EUS-CDS dysfunction, potentially representing a relative contraindication for this technique.

RESUMO

BACKGROUND: For palliative drainage of inoperable perihilar cholangiocarcinoma (pCCA) uncovered metal stents are preferred over plastic stents. However, there is a lack of data on re-interventions at the long-term. The aim is to evaluate the potential difference in the number of re-interventions in patients surviving at least 6 months. METHODS: Retrospective study including patients with pCCA who underwent plastic stent placement(s) or had metal stent(s) in situ for at least 6 months. The primary outcome was the number of re-interventions per patient-year. A propensity score matching (1:1) analysis was performed using age, Bismuth classification, reason for inoperability, pathological confirmation, systemic therapy and initial approach (endoscopic vs percutaneous). RESULTS: Patients in the metal stent group (n = 87) underwent fewer re-interventions compared with the plastic stent group (n = 40) (3.0 vs. 4.7 per patient-year; IRR, 0.64; 95% CI, 0.47 to 0.88). When only non-elective re-interventions were included, there was no significant difference (2.1 vs. 2.7; IRR, 0.76; 95% CI, 0.55 to 1.08). Results were similar in the propensity score-matched dataset. CONCLUSIONS: This study shows that, also in patients with inoperable pCCA who survive at least 6 months, placement of metal stent(s) leads to fewer re-interventions in comparison with plastic stents.

RESUMO

1: ESGE recommends a prolonged course of a prophylactic broad-spectrum antibiotic in patients with ascites who are undergoing therapeutic endoscopic ultrasound (EUS) procedures.Strong recommendation, low quality evidence. 2: ESGE recommends placement of partially or fully covered self-expandable metal stents during EUS-guided hepaticogastrostomy for biliary drainage in malignant disease.Strong recommendation, moderate quality evidence. 3: ESGE recommends EUS-guided pancreatic duct (PD) drainage should only be performed in high volume expert centers, owing to the complexity of this technique and the high risk of adverse events.Strong recommendation, low quality evidence. 4: ESGE recommends a stepwise approach to EUS-guided PD drainage in patients with favorable anatomy, starting with rendezvous-assisted endoscopic retrograde pancreatography (RV-ERP), followed by antegrade or transmural drainage only when RV-ERP fails or is not feasible.Strong recommendation, low quality evidence. 5: ESGE suggests performing transduodenal EUS-guided gallbladder drainage with a lumen-apposing metal stent (LAMS), rather than using the transgastric route, as this may reduce the risk of stent dysfunction.Weak recommendation, low quality evidence. 6: ESGE recommends using saline instillation for small-bowel distension during EUS-guided gastroenterostomy.Strong recommendation, low quality evidence. 7: ESGE recommends the use of saline instillation with a 19G needle and an electrocautery-enhanced LAMS for EUS-directed transgastric endoscopic retrograde cholangiopancreatography (EDGE) procedures.Strong recommendation, low quality evidence. 8: ESGE recommends the use of either 15- or 20-mm LAMSs for EDGE, with a preference for 20-mm LAMSs when considering a same-session ERCP.Strong recommendation, low quality evidence.

RESUMO

1: ESGE recommends the use of endoscopic ultrasound-guided biliary drainage (EUS-BD) over percutaneous transhepatic biliary drainage (PTBD) after failed endoscopic retrograde cholangiopancreatography (ERCP) in malignant distal biliary obstruction when local expertise is available.Strong recommendation, moderate quality evidence. 2: ESGE suggests EUS-BD with hepaticogastrostomy only for malignant inoperable hilar biliary obstruction with a dilated left hepatic duct when inadequately drained by ERCP and/or PTBD in high volume expert centers.Weak recommendation, moderate quality evidence. 3: ESGE recommends that EUS-guided pancreatic duct (PD) drainage should only be considered in symptomatic patients with an obstructed PD when retrograde endoscopic intervention fails or is not possible.Strong recommendation, low quality evidence. 4: ESGE recommends rendezvous EUS techniques over transmural PD drainage in patients with favorable anatomy owing to its lower rate of adverse events.Strong recommendation, low quality evidence. 5: ESGE recommends that, in patients at high surgical risk, EUS-guided gallbladder drainage (GBD) should be favored over percutaneous gallbladder drainage where both techniques are available, owing to the lower rates of adverse events and need for re-interventions in EUS-GBD.Strong recommendation, high quality of evidence. 6: ESGE recommends EUS-guided gastroenterostomy (EUS-GE), in an expert setting, for malignant gastric outlet obstruction, as an alternative to enteral stenting or surgery.Strong recommendation, low quality evidence. 7: ESGE recommends that EUS-GE may be considered in the management of afferent loop syndrome, especially in the setting of malignancy or in poor surgical candidates. Strong recommendation, low quality evidence. 8: ESGE suggests that endoscopic ultrasound-directed transgastric ERCP (EDGE) can be offered, in expert centers, to patients with a Roux-en-Y gastric bypass following multidisciplinary decision-making, with the aim of overcoming the invasiveness of laparoscopy-assisted ERCP and the limitations of enteroscopy-assisted ERCP.Weak recommendation, low quality evidence.

RESUMO

BACKGROUND: Endoscopic duodenal stenting is the current standard treatment for malignant gastric outlet obstruction (GOO) in patients with limited life expectancy. However, duodenal stenting is prone to stent dysfunction. Endoscopic ultrasound-guided gastroenterostomy (EUS-GE) is a novel technique with potentially superior stent patency. We compared clinical success, safety, and stent dysfunction of EUS-GE and duodenal stenting in patients with malignant GOO using propensity score matching. METHODS: This international, multicenter, retrospective study analyzed consecutive patients undergoing EUS-GE or duodenal stenting for GOO between 2015 and 2021 in three European centers. Primary outcomes were clinical success (GOO scoring system [GOOSS] ≥ 2) and stent dysfunction (GOOSS ≤ 1 after initial clinical success). A propensity score matching (1:1) analysis was performed using age, sex, underlying disease, disease stage, ascites, and peritoneal carcinomatosis as variables. RESULTS: 214 patients underwent EUS-GE (n = 107) or duodenal stenting (n = 107). After propensity score matching, 176 patients were matched and compared. Technical success rates for EUS-GE and duodenal stenting were 94 % (95 %CI 89 %-99 %) vs. 98 % (95 %CI 95 %-100 %), respectively (P = 0.44). Clinical success rates were 91 % (95 %CI 85 %-97 %) vs. 75 % (95 %CI 66 %-84 %; P = 0.008). Stent dysfunction occurred in 1 % (95 %CI 0-4 %) vs. 26 % (95 %CI 15 %-37 %) of patients (P < 0.001). Adverse event rate was 10 % (95 %CI 4 %-17 %) vs. 21 % (95 %CI 12 %-29 %; P = 0.09). CONCLUSION: EUS-GE had higher clinical success and lower stent dysfunction, with similar safety, compared with duodenal stenting, suggesting that EUS-GE may be preferred over duodenal stenting in patients with malignant GOO.

RESUMO

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.

RESUMO

Immune-mediated enteropathies are caused by excessive reactions of the intestinal immune system towards non-pathogenic molecules. Enteropathy leads to malabsorption-related symptoms and include (severe) chronic diarrhea, weight loss and vitamin deficiencies. Parenteral feeding and immunosuppressive therapy are needed in severe cases. Celiac disease has long been recognized as the most common immune-mediated enteropathy in adults, but the spectrum of immune-mediated enteropathies has been expanding. Histological and clinical features are sometimes shared among these enteropathies, and therefore it may be challenging to differentiate between them. Here, we provide an overview of immune-mediated enteropathies focused on clinical presentation, establishing diagnosis, immunopathogenesis, and treatment options.

RESUMO

BACKGROUND AND AIMS: In the management of gastric outlet obstruction (GOO), EUS-guided gastroenterostomy (EUS-GE) seems to be safe and more effective than enteral stent placement. However, comparisons with laparoscopic GE (L-GE) are scarce. Our aim was to perform a propensity score-matched comparison between EUS-GE and L-GE. METHODS: An international, multicenter, retrospective analysis was performed of consecutive EUS-GE and L-GE procedures in 3 academic centers (January 2015 to May 2020) using propensity score matching to minimize selection bias. A standard maximum propensity score difference of .1 was applied, also considering underlying disease and oncologic staging. RESULTS: Overall, 77 patients were treated with EUS-GE and 48 patients with L-GE. By means of propensity score matching, 37 patients were allocated to both groups, resulting in 74 (1:1) matched patients. Technical success was achieved in 35 of 37 EUS-GE-treated patients (94.6%) versus 100% in the L-GE group (P = .493). Clinical success, defined as eating without vomiting or GOO Scoring System ≥2, was achieved in 97.1% and 89.2%, respectively (P = .358). Median time to oral intake (1 [interquartile range {IQR}, .3-1.0] vs 3 [IQR, 1.0-5.0] days, P < .001) and median hospital stay (4 [IQR, 2-8] vs 8 [IQR, 5.5-20] days, P < .001) were significantly shorter in the EUS-GE group. Overall (2.7% vs 27.0%, P = .007) and severe (.0% vs 16.2%, P = .025) adverse events were identified more frequently in the L-GE group. CONCLUSIONS: For patients with GOO, EUS-GE and L-GE showed almost identical technical and clinical success. However, reduced time to oral intake, shorter median hospital stay, and lower rate of adverse events suggest that the EUS-guided approach might be preferable.
