RESUMO
BACKGROUND AND AIM: This study aimed to determine safety and risk factors for adverse events (AEs) of endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) with long-term indwell of lumen-apposing metal stents (LAMS). METHODS: This study is a multicenter prospective observational study on consecutive high surgical-risk patients requiring gallbladder drainage who underwent EUS-GBD with LAMS over 12 months. Centralized telephone follow-up interviews were conducted every 3 months for 1 year. Patients were censored at LAMS removal, cholecystectomy, or death. AE-free survival was determined using log-rank tests. Cumulative risks were estimated using life-table analysis. RESULTS: Eighty-two patients were included (53.7% male, median [interquartile range] age of 84.6 [76.5-89.8] years, and 85.4% with acute cholecystitis). Technical success was achieved in 79 (96.3%), and clinical success in 73 (89%). No patient was lost to follow-up; 45 patients (54.9%) completed 1-year follow-up with in situ LAMS. Median (interquartile range) LAMS indwell time was 364 (47-367) days. Overall, 12 (14.6%) patients presented 14 AEs, including 5 (6.1%) recurrent biliary events (3 acute cholangitis, 1 mild acute pancreatitis, and 1 acute cholecystitis). Patients with pancreatobiliary malignancy had an increased risk of recurrent biliary events (33% vs 1.5%, P = 0.001). The overall 1-year cumulative risk of recurrent biliary events was 9.7% (4.1-21.8%). The 1-year risk of AEs and of severe AEs was 18.8% (11-31.2%) and 7.9% (3.3-18.2%), respectively. Pancreatobiliary malignancy was the single risk factor for recurrent biliary events; LAMS misdeployment was the strongest risk factor for AEs. CONCLUSIONS: Long-term LAMS indwell does not increase the risk of delayed AEs following EUS-GBD.

Acute pancreatitis is associated with significant morbidity and mortality. It can develop complications such as fluid collections and necrosis. Infection of necrosis occurs in about 20-40 % of patients with severe acute pancreatitis, and is associated with organ failure and worse prognosis. In the past few years the treatment of pancreatic collections has shifted from open surgery to minimally invasive techniques such as endoscopic ultrasound-guided drainage. These guidelines from a selection of experts among the Endoscopic Ultrasound Group, Spanish Society of Gastrointestinal Endoscopy (GSEED-USE) are intended to provide advice on the management of pancreatic collections based on a thorough review of the available scientific evidence. It also reflects the experience and clinical practice of the authors, who are advanced endoscopists or clinical pancreatologists with extensive experience in managing patients with acute pancreatitis.

BACKGROUND: Removing lumen-apposing metal stents (LAMSs) may be difficult and even harmful, but these features have seldom been analyzed. We aimed to generate a comprehensive assessment of the feasibility and safety of LAMS retrieval procedures. METHODS: A prospective multicenter case series including all technically successfully deployed LAMSs between January 2019 and January 2020 that underwent endoscopic stent removal. All retrieval-related data were prospectively recorded using standardized telephone questionnaires as part of centralized follow-up that ended after stent removal had been performed. Multivariable logistic regression models assessed the potential risk factors for complex removal. RESULTS: For the 407 LAMSs included, removal was attempted in 158 (38.8â%) after an indwell time of 46.5 days (interquartile range [IQR] 31-70). The median (IQR) removal time was 2 (1-4) minutes. Removal was labelled as complex in 13 procedures (8.2â%), although advanced endoscopic maneuvers were required in only two (1.3â%). Complex removal risk factors were stent embedment (relative risk [RR] 5.84, 95â%CI 2.14-15.89; Pâ=â0.001), over-the-wire deployment (RR 4.66, 95â%CI 1.60-13.56; Pâ=â0.01), and longer indwell times (RR 1.14, 95â%CI 1.03-1.27; Pâ=â0.01). Partial and complete embedment were observed in 14 (8.9â%) and five cases (3.2â%), respectively. The embedment rate during the first 6 weeks was 3.1â% (2/65), reaching 15.9â% (10/63) during the following 6 weeks (Pâ=â0.02). The adverse event rate was 5.1â%, including seven gastrointestinal bleeds (5 mild, 2 moderate). CONCLUSIONS: LAMS removal is a safe procedure, mostly requiring basic endoscopic techniques attainable in conventional endoscopy rooms. Referral to advanced endoscopy units should be considered for stents with known embedment or long indwell times, which may require more technically demanding procedures.

Endoscopic retrograde cholangiopancreatography (ERCP) is the technique of choice for the treatment of biliopancreatic pathology. However, fluoroscopic imaging does not always allow an adequate diagnosis. On the other hand, some large stones cannot be removed by the usual methods. In these situations, cholangioscopy has proven to be an essential tool for the diagnosis of biliary strictures and the treatment of large stones. Its role in pancreatic pathology is also increasing. The development of a single-operator, disposable cholangioscope has made it possible to expand the technique to a large number of hospitals that perform ERCP. For this reason, the Spanish Society of Digestive Endoscopy has developed this consensus document on the use of the Spyglass-DS cholangioscope. The document has been prepared by a group of endoscopists with expertise in cholangioscopy, reviewing the scientific evidence on the main current indications for cholangiopancreatoscopy.

INTRODUCTION: deep sedation controlled by the endoscopist is safe in patients with low anesthetic risk (ASA I-II). However, scarce evidence is available in patients with intermediate risk (ASA III). OBJECTIVE: to evaluate the safety of deep sedation with propofol controlled by the usual endoscopy staff (endoscopist, nurse, assistant) in outpatients classified as ASA III and the risk factors for the occurrence of complications during deep sedation. PATIENTS AND METHODS: this observational and single-center cross-sectional study included consecutive patients undergoing non-complex procedures in which deep sedation was administered by the endoscopy staff. Patients were divided into group I (ASA = III) and group II (ASA < III). RESULTS: a total of 562 patients were included and 80 (14.2 %) were in group I. Complications related to deep sedation were more frequent in group I (23.8 % vs 14.5 %; p = 0.036), mainly mild desaturations (13.8 % vs 7.5 %; p = 0.058). Emergency intervention or death were not registered. The adjusted analysis identified age as the only independent baseline risk factor for developing global adverse events. CONCLUSION: ASA III patients developed more sedation-related complications than ASA I-II patients. However, these complications were mild and did not prevent the correct performance of the procedure.

INTRODUCTION: there is controversy with regard to the risks associated with lumen-apposing metal stents (LAMSs), with significant variations between available reports. OBJECTIVES: to describe the types and proportions of complications that arise during the permanence time and removal of Axios™ LAMS. Furthermore, the relationship between patency time, therapeutic target and the presence of complications was also described. METHODS: a retrospective, multicenter case series study was performed of all patients with an implanted LAMS to access extra-luminal structures during 2017. Only technically successful cases were recorded. RESULTS: a total of 179 patients from seven sites (range, 4-68 cases/site) were included in the study, with a mean age of 64.3 years (SD: 15.8; range: 24.6-98.8 years) and 122 (68.2%) were male. Most common indications included encapsulated necrosis (58, 32.4%), pseudocysts (31, 17.3%) and gallbladder drains (26, 14.5%). Complications during LAMS stay were reported in 19 patients (10.9%); stent lumen or gastroduodenal obstruction (8, 4.5%) and bleeding (7, 3.9%) were the most common. LAMS were not removed in 86 (48%) patients due to the following reasons: a permanent stent was used (46, 53.5%), loss to follow-up (18, 20.9%), patient demise (16, 18.6%) and stent migration (6, 7%). Five (5.4%) complications were reported during stent removal, which were three bleeds and two perforations. No association was found between stent duration and complications (p = 0.67). CONCLUSION: complications secondary to LAMS insertion are uncommon but may be serious. This study found no association between complications and stent duration.

With the increasingly widespread use of imaging techniques pancreatic cystic lesions (PCLs) are now commonly identified. Their prevalence among the symptom-free population ranges from 2.4% to 13.5%. However, a recent study by our group revealed PCLs in up to 21.5% of patients undergoing endoscopic ultrasound (EUS) for non-pancreas conditions, an incidence that increases with age. Identifying PCLs in an otherwise asymptomatic population has become a significant clinical issue.

BACKGROUND AND OBJECTIVES: Before starting programs for colorectal cancer screening it is necessary to evaluate the quality of colonoscopy. Our objectives were to develop a group of quality indicators of colonoscopy easily applicable and to determine the variability of their achievement. PATIENTS AND METHODS: After reviewing the bibliography we prepared 21 potential indicators of quality that were submitted to a process of selection in which we measured their facial validity, content validity, reliability and viability of their measurement. We estimated the variability of their achievement by means of the coefficient of variability (CV) and the variability of the achievement of the standards by means of chi(2). RESULTS: Six indicators overcome the selection process: informed consent, medication administered, completed colonoscopy, complications, every polyp removed and recovered, and adenoma detection rate in patients older than 50 years. 1928 colonoscopies were included from eight endoscopy units. Every unit included the same number of colonoscopies selected by means of simple random sampling with substitution. There was an important variability in the achievement of some indicators and standards: medication administered (CV 43%, p<0.01), complications registered (CV 37%, p<0.01), every polyp removed and recovered (CV 12%, p<0.01) and adenoma detection rate in older than fifty years (CV 2%, p<0.01). CONCLUSIONS: We have validated six quality indicators for colonoscopy which are easily measurable. An important variability exists in the achievement of some indicators and standards. Our data highlight the importance of the development of continuous quality improvement programmes for colonoscopy before starting colorectal cancer screening.
