RESUMEN
Pancreatic fluid collections (PFCs), including pancreatic pseudocysts (PPs) and walled-off pancreatic necrosis (WON), are common complications of pancreatitis and pancreatic surgery. Historically, the treatment of these conditions has relied on surgical and radiological approaches; however, it has later shifted toward an endoscopy-based approach. With the development of dedicated lumen-apposing metal stents (LAMS), interventional Endoscopic Ultrasound (EUS)-guided procedures have become the standard approach for PFC drainage. However, there is still limited consensus on several aspects of the multidisciplinary management of PFCs. The interventional endoscopy and ultrasound (i-EUS) group is an Italian network of clinicians and scientists with special interest in biliopancreatic interventional endoscopy, especially interventional EUS. This manuscript describes the first part of the results of a consensus conference organized by i-EUS with the aim of providing evidence-based guidance on aspects such as indications for treating PFCs, the timing of intervention, and different technical strategies for managing patients with PFCs.
RESUMEN
Despite the introduction of serological neoplastic biomarkers and typical radiological characteristics in clinical practice, liver biopsy (LB) is often still necessary to establish a histological diagnosis, especially in ambiguous cases. Nowadays, LB via the percutaneous approach (PC-LB), under computed tomography (CT) scan or ultrasonography (US) guidance, is the route of choice. However, certain focal liver lesions can be challenging to access percutaneously. In such cases, endoscopic ultrasound (EUS)-guided fine needle biopsy (FNB) may represent an attractive, minimally invasive alternative. This retrospective observational study aimed to evaluate the efficacy, diagnostic performance, and safety of EUS-FNB conducted on 58 focal liver lesions located in both liver lobes. The adequacy of FNB samples for focal liver lesions located in the left and right lobes was 100% and 81.2%, respectively, and the difference was statistically significant (p = 0.001). Technical success was 100% for both liver lobes. The overall sensitivity and specificity were 95% and 100%, respectively. EUS-FNB is effective in making an accurate diagnosis with an excellent safety profile for focal liver lesions located in both liver lobes.
RESUMEN
Pancreatic fluid collections (PFCs), including pancreatic pseudocysts (PPs) and walled-off pancreatic necrosis (WON), are common complications of pancreatitis and pancreatic surgery. Historically, the treatment of these conditions has relied on surgical and radiological approaches. The treatment of patients with PFCs has already focused toward an endoscopy-based approach, and with the development of dedicated lumen-apposing metal stents (LAMS), it has almost totally shifted towards interventional Endoscopic Ultrasound (EUS)-guided procedures. However, there is still limited consensus on several aspects of PFCs treatment within the multidisciplinary management. The interventional endoscopy and ultrasound (i-EUS) group is an Italian network of clinicians and scientists with special interest in biliopancreatic interventional endoscopy, especially interventional EUS. This manuscript focuses on the second part of the results of a consensus conference organized by i-EUS, with the aim of providing evidence-based guidance on several intra- and post-procedural aspects of PFCs drainage, such as clinical management and follow-up.

Mirizzi syndrome (MS) is a challenging diagnosis due to its similar presentation with other biliary diseases; thus, the role of endoscopy is sometimes unclear, especially in altered anatomy. Radiological examinations may usually suspect it, but deeper examinations could be necessary to confirm it. Endoscopic retrograde cholangiopancreatography (ERCP) certainly has a therapeutic role in cases of jaundice, cholangitis or concurrent choledocolithiasis, although surgery is without doubt the definitive treatment in most of the cases. Therefore, surgeons may have a clearer picture of the condition of the biliary tree with respect to fistulas thanks to ERCP, particularly in patients with a higher grade of MS (type higher than 2 in the Csendes classification). Therefore, a complete removal of biliary stones is sometimes not possible due to size and location, so biliary stenting becomes the only option, even if transitory. Our brief report is a further demonstration of the fundamental role of ERCP in managing MS, even when it has no long-term therapeutic aim but is performed as bridge-to-surgery, especially in cases with a more difficult biliary anatomy due to the type of fistula. Moreover, we truly suggest discussing patients affected with MS in a multidisciplinary board, preferably in tertiary hepatobiliary centers.
RESUMEN
Background and Objectives: Biliary drainage (BD) in patients with surgically altered anatomy (SAA) could be obtained endoscopically with different techniques or with a percutaneous approach. Every endoscopic technique could be challenging and not clearly superior over another. The aim of this survey is to explore which is the standard BD approach in patients with SAA. Materials and Methods: A 34-question online survey was sent to different Italian tertiary and non-tertiary endoscopic centers performing interventional biliopancreatic endoscopy. The core of the survey was focused on the first-line and alternative BD approaches to SAA patients with benign or malignant obstruction. Results: Out of 70 centers, 39 answered the survey (response rate: 56%). Only 48.7% of them declared themselves to be reference centers for endoscopic BD in SAA. The total number of procedures performed per year is usually low, especially in non-tertiary centers; however, they have a low tendency to refer to more experienced centers. In the case of Billroth-II reconstruction, the majority of centers declared that they use a duodenoscope or forward-viewing scope in both benign and malignant diseases as a first approach. However, in the case of failure, the BD approach becomes extremely heterogeneous among centers without any technique prevailing over the others. Interestingly, in the case of Roux-en-Y, a significant proportion of centers declared that they choose the percutaneous approach in both benign (35.1%) and malignant obstruction (32.4%) as a first option. In the case of a previous failed attempt at BD in Roux-en-Y, the subsequent most used approach is the EUS-guided intervention in both benign and malignant indications. Conclusions: This survey shows that the endoscopic BD approach is extremely heterogeneous, especially in patients with Roux-en-Y reconstruction or after ERCP failure in Billroth-II reconstruction. Percutaneous BD is still taken into account by a significant proportion of centers in the case of Roux-en-Y anatomy. The total number of endoscopic BD procedures performed in non-tertiary centers is usually low, but this result does not correspond to an adequate rate of referral to more experienced centers.

BACKGROUND: Although endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) using lumen-apposing metal stents (LAMS) has become one of the treatments of choice for acute cholecystitis (AC) in fragile patients, scant data are available on real-life settings and long-term outcomes. METHODS: We performed a multicenter retrospective study including EUS-guided GBD using LAMS for AC in 19 Italian centers from June 2014 to July 2020. The primary outcomes were technical and clinical success, and the secondary outcomes were the rate of adverse events (AE) and long-term follow-up. RESULTS: In total, 116 patients (48.3% female) were included, with a mean age of 82.7 ± 11 years. LAMS were placed, transgastric in 44.8% of cases, transduodenal in 53.3% and transjejunal in 1.7%, in patients with altered anatomy. Technical success was achieved in 94% and clinical success in 87.1% of cases. The mean follow-up was 309 days. AEs occurred in 12/116 pts (10.3%); 8/12 were intraprocedural, while 1 was classified as early (<15 days) and 3 as delayed (>15 days). According to the ASGE lexicon, two (16.7%) were mild, three (25%) were moderate, and seven (58.3%) were severe. No fatal AEs occurred. In subgroup analysis of 40 patients with a follow-up longer than one year, no recurrence of AC was observed. CONCLUSIONS: EUS-GBD had high technical and clinical success rates, despite the non-negligible rate of AEs, thus representing an effective treatment option for fragile patients.
RESUMEN
BACKGROUND: Endoscopic ultrasonography-guided gastroenterostomy (EUS-GE) is a novel endoscopic method to palliate malignant gastric outlet obstruction. We aimed to assess whether the use of EUS-GE with a double balloon occluder for malignant gastric outlet obstruction could reduce the need for reintervention within 6 months compared with conventional duodenal stenting. METHODS: The was an international, multicentre, randomised, controlled trial conducted at seven sites in Hong Kong, Belgium, Brazil, India, Italy, and Spain. Consecutive patients (aged ≥18 years) with malignant gastric outlet obstruction due to unresectable primary gastroduodenal or pancreatobiliary malignancies, a gastric outlet obstruction score (GOOS) of 0 (indicating an inability in intake food or liquids orally), and an Eastern Cooperative Oncology Group performance status score of 3 or lower were included and randomly allocated (1:1) to receive either EUS-GE or duodenal stenting. The primary outcome was the 6-month reintervention rate, defined as the percentage of patients requiring additional endoscopic intervention due to stent dysfunction (ie, restenosis of the stent due to tumour ingrowth, tumour overgrowth, or food residue; stent migration; or stent fracture) within 6 months, analysed in the intention-to-treat population. Prespecified secondary outcomes were technical success (successful placement of a stent), clinical success (1-point improvement in gastric outlet obstruction score [GOOS] within 3 days), adverse events within 30 days, death within 30 days, duration of stent patency, GOOS at 1 month, and quality-of-life scores. This study is registered with ClinicalTrials.gov (NCT03823690) and is completed. FINDINGS: Between Dec 1, 2020, and Feb 28, 2022, 185 patients were screened and 97 (46 men and 51 women) were recruited and randomly allocated (48 to the EUS-GE group and 49 to the duodenal stent group). Mean age was 69·5 years (SD 12·6) in the EUS-GE group and 64·8 years (13·0) in the duodenal stent group. All randomly allocated patients completed follow-up and were analysed. Reintervention within 6 months was required in two (4%) patients in the EUS-GE group and 14 (29%) in the duodenal stent group [p=0·0020; risk ratio 0·15 [95% CI 0·04-0·61]). Stent patency was longer in the EUS-GE group (median not reached in either group; HR 0·13 [95% CI 0·08-0·22], log-rank p<0·0001). 1-month GOOS was significantly better in the EUS-GE group (mean 2·41 [SD 0·7]) than the duodenal stent group (1·91 [0·9], p=0·012). There were no statistically significant differences between the EUS-GE and duodenal stent groups in death within 30 days (ten [21%] vs six [12%] patients, respectively, p=0·286), technical success, clinical success, or quality-of-life scores at 1 month. Adverse events occurred 11 (23%) patients in the EUS-GE group and 12 (24%) in the duodenal stent group within 30 days (p=1·00); three cases of pneumonia (two in the EUS-GE group and one in the duodenal stent group) were considered to be procedure related. INTERPRETATION: In patients with malignant gastric outlet obstruction, EUS-GE can reduce the frequency of reintervention, improve stent patency, and result in better patient-reported eating habits compared with duodenal stenting, and the procedure should be used preferentially over duodenal stenting when expertise and required devices are available.

BACKGROUND: The new dedicated stents for endoscopic ultrasound (EUS)-guided transluminal drainage of peripancreatic fluid collections (PFCs) demonstrated optimal efficacy and safety profiles. AIMS: This study aimed to evaluate the safety, technical and clinical success, and recurrence rate of PFCs drained with Lumen Apposing Metal Stent (LAMS) or Bi-Flanged Metal Stent (BFMS). METHODS: Data from a multicenter series of PFCs treated with LAMS or BFMS at 30 Italian centers during a 5-year period were retrieved. The rate of adverse events (AEs), technical success, clinical success, PFC recurrence were evaluated. To overcome biases, a 1-to-1 match was created using propensity score analysis. RESULTS: Out of 476 patients, 386 were treated with LAMS and 90 with BFMS, with a median follow-up of 290 days (95% CI 244 to 361). Using propensity score matching, 84 patients were assigned to each group. The incidence of AEs did not differ between the two stents (13.1% versus 15.5%, p = 0.29), mainly bleeding or recurrence rate (4.7% versus 3.5%, p = 1). Technical and clinical success in the BFMS and LAMS groups were 92% versus 95% (p = 0.36) and 91% versus 94% (p = 0.64), respectively. CONCLUSION: Our study demonstrates that LAMS and BFMS have comparable safety profiles with similar technical and clinical success rates for EUS-guided PFC drainage.

RESUMEN
Therapeutic endoscopy permits many and various treatments for cancer palliation in patients with bilio-pancreatic cancers, enabling different options, supporting patients during their route to oncologic treatments, and trying to improve their quality of life. Therefore, both endoscopic and endoscopic ultrasound (EUS)-guided techniques are performed in this scenario. We performed a literature review focusing on the role of endoscopy in the palliation of those advanced pancreatic and biliary cancers developing malignant biliary obstruction (MBO), gastric outlet obstruction (GOO), and pain unresponsive to medical therapies. Therefore, we explored and focused on the clinical outcomes of endoscopic procedures in this scenario. In fact, the endoscopic treatment is based on achieving biliary drainage in the case of MBO through endoscopic retrograde cholangiopancreatography (ERCP) or EUS-guided biliary drainage (EUS-BD), while GOO is endoscopically treated through the deployment of an enteral stent or the creation of EUS-guided gastro-entero-anastomosis (EUS-GEA). Furthermore, untreatable chronic abdominal pain is a major issue in patients unresponsive to high doses of painkillers, so EUS-guided celiac plexus neurolysis (CPN) or celiac ganglia neurolysis (CGN) helps to reduce dosage and have better pain control. Therefore, therapeutic endoscopy in the palliative setting is an effective and safe approach for managing most of the clinical manifestations of advanced biliopancreatic tumors.

RESUMEN
BACKGROUND AND AIMS: EUS-guided gallbladder drainage (EUS-GBD) with lumen-apposing metal stents (LAMSs) has been reported as a rescue treatment with encouraging results for the relief of jaundice in patients with distal malignant biliary obstruction (DMBO) and after failure of both ERCP and EUS-guided choledochoduodenostomy. METHODS: This was a multicenter retrospective analysis of all cases of consecutive EUS-GBD with LAMSs used as a rescue treatment for patients with DMBO in 14 Italian centers from June 2015 to June 2020. Primary endpoints were technical and clinical success, whereas the secondary endpoint was the adverse event (AE) rate. RESULTS: Forty-eight patients (52.1% women) with a mean age of 74.3 ± 11.7 years were included in the study. Biliary stricture was related to pancreatic adenocarcinoma (85.4%), duodenal adenocarcinoma (2.1%), cholangiocarcinoma (4.2%), ampullary cancer (2.1%), colon cancer (4.2%), and metastatic breast cancer (2.1%). The mean diameter of the common bile duct was 13.3 ± 2.8 mm. LAMSs were placed transgastrically in 58.3% of cases and transduodenally in 41.7%. Technical success was 100%, whereas clinical success was 81.3%, with a mean total bilirubin reduction after 2 weeks of 66.5%. The mean procedure time was 26.4 minutes, and the mean hospital stay was 9.2 ± 8.2 days. AEs occurred in 5 patients (10.4%): 3 were classified as intraprocedural and 2 were classified as delayed because they occurred after >15 days. When the American Society for Gastrointestinal Endoscopy lexicon was used, 2 AEs were mild and 3 were moderate (2 buried LAMSs). The mean follow-up was 122 days. CONCLUSIONS: Our study shows that EUS-GBD with LAMSs used as a rescue treatment for patients affected by DMBO represents a valuable option in terms of technical and clinical success rates, with an acceptable AE rate. To the best of our knowledge, this is the largest study concerning the use of this procedure. (Clinical trial registration number: NCT03903523.).
