Background: The rising prevalence of gastric, biliary, and pancreatic surgeries has led to an increasing population of patients with surgically altered anatomy (SAA). In this setting, conventional endoscopic retrograde cholangiopancreatography (ERCP) is often limited by anatomical barriers, resulting in high rates of technical failure and complications. While device-assisted enteroscopy (DAE) has expanded therapeutic possibilities, its efficacy remains modest in complex reconstructions. Methods: This review analyzed recent literature from PubMed, Embase, and Scopus up to April 2025, focusing on diagnostic and therapeutic roles of endoscopic ultrasound (EUS) in SAA. Particular attention was given to cases where standard endoscopic, percutaneous, or surgical techniques failed and to studies comparing EUS-guided approaches with alternative modalities. Results: EUS has transitioned from a primarily diagnostic modality to a versatile therapeutic platform in SAA. Techniques such as EUS-guided rendezvous, antegrade drainage, and hepaticogastrostomy have shown technical and clinical success rates exceeding 80–90%, often comparable or superior to interventional radiology, while reducing the need for external drains. Innovative procedures, including EUS-directed transgastric ERCP (EDGE) and EUS-directed enteroenteric bypass (EDEE), have transformed the management of Roux-en-Y gastric bypass and bilioenteric anastomoses, providing durable and reusable access for repeated interventions. Despite these advances, EUS-guided interventions remain technically demanding, requiring advanced endoscopic and radiologic skills, specialized devices, and are best performed in tertiary referral centers. Conclusions: EUS has redefined the treatment paradigm of biliopancreatic diseases in patients with SAA, increasingly emerging as the preferred minimally invasive approach when conventional techniques fail. Future developments will focus on dedicated devices, standardized guidelines, and structured training programs to optimize outcomes. Multidisciplinary collaboration and centralization in high-volume centers remain essential to ensure safety, efficacy, and reproducibility.

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.

Background and Study Aim: Advance biliopancreatic endoscopies are nowadays performed in non-operating room anesthesia (NORA) under general anesthesia (GA). We evaluate the outcomes of non-intubated patients in prone position who received GA for endoscopic ultrasound (EUS) and endoscopic retrograde cholangiopancreatography (ERCP) in a tertiary referral center for digestive endoscopy. Patients and Methods: Anesthesiological records, anamnestic, and intraoperative data of patients who underwent advanced therapeutic biliopancreatic endoscopies at our tertiary referral center from January 2019 until January 2020 were collected in the present observational study. Results: One hundred fifty-three patients (93 M; median age: 68-year-old; mean ASA status: 2) were considered eligible for a procedure in the prone position with GA in spontaneous breathing. Prone position was always the initial setting. Propofol administration through a target-controlled infusion (TCI) pump was the choice to achieve GA. In our experience, desaturation appears to be the most frequent adverse event, accounting for 35% of cases (55/153). Treatment foresaw additional oxygen through a nasopharyngeal catheter, which proved to be a sufficient measure in almost all patients (52/55). Other adverse events (i.e., inadequate sedative plan, pain, and bradycardia) accounted for 2.6% of cases (4/153). Conclusions: Non-intubated GA in the prone position may be regarded as a safe procedure, as long as the anesthesiological criteria of exclusion are respected and the anesthesiological team has become acquainted with the peculiar NORA setting and familiar with the management of possible adverse events.

Background: Postoperative fluid collections (POFCs) after abdominal surgeries, particularly pancreatic surgeries, are associated with high morbidity and mortality rates and were historically managed with surgical re-exploration and drainage. In particular, postoperative pancreatic fluid collections (PPFCs) are the most common complications after pancreatic surgery resulting from pancreatic leaks. They occur in up to 50% of cases, and approximately 10% of them need to be drained to avoid further sequelae. Endoscopic ultrasonography (EUS)-guided drainage of PPFCs represents the first-line treatment nowadays, but many aspects are still debated. Methods: We describe a retrospective case series of patients from multiple Italian centers who underwent EUS-guided drainage (EUS-D) of POFCs, aiming to provide data on the efficacy and safety of this procedure, supported by a review of the existing literature on this topic. The primary outcomes were technical and clinical success, and the secondary outcomes were the type and rate of adverse events (AEs) and the rate of recurrence. Results: A total of 47 patients were included. The procedure demonstrated a technical success rate of 98% (46/47) and a clinical success rate of 96% (45/47). The rate of AEs was 11% (5/47), represented by bleeding (3/5), stent occlusion (1/5), and buried syndrome (1/5). Conclusions: Management of POFCs has shifted over time towards an endoscopic approach with optimal efficacy and safety.

Dysphagia in patients with lung cancer is usually due to direct invasion from bronchogenic carcinomas or nodal localizations, while metastases from distant lung neoplasms are considered rare. We report a case of a smooth esophageal narrowing secondary to intramural metastasis from pulmonary adenocarcinoma in a patient with no previous history of neoplasia. Since standard linear echoendoscope could not overpass the malignant stricture, we obtained a histological diagnosis by fine-needle aspiration biopsy using an echobronchoscope (EBUS), due to its lower diameter. The EBUS scope represents a valuable tool to obtain cytological specimens in patients with esophageal strictures.

Cricopharyngeal myotomy with flexible endoscope is a well-known and safe treatment for Zenker’s diverticulum. We describe hereafter how we perform this flexible endotherapy. From January 2011 to January 2017, we treated 28 patients with this endotherapy. Our technique is described step-by-step in the paper: the main principle is to perform an endoscopic cut of the diverticular septum and cricopharyngeal muscle’s fibers (see the video). We describe an objective measurement of the cutting length and depth of the myotomy. Technical success was achieved in all the patients. As to clinical success, 76.2% of patients showed a significant improvement and relevant disappearance of preoperative dysphagia. The present follow-up ranges from 6 months to 5 years. This flexible endoscopic technique can overcome some limitations of rigid endoscopic technique (i.e., upper teeth protrusion, inadequate jaw opening, or limited neck mobility). The main indication was based on clinical presentation and referred to the diverticular dimensions between 2 and 5 cm. Tips for the technique are described in the paper. This variant of cricopharyngeal myotomy with flexible endoscopy is feasible and effective for the treatment of Zenker’s diverticulum in selected patients.

Background and aimIn surgically altered anatomy (SAA), endoscopic retrograde cholangiopancreatography (ERCP) can be challenging, and it remains debatable the choice of the optimal endoscopic approach within this context.We aim to show our experience and evaluate the technical and clinical success of endoscopic treatment performed in the setting of adverse events (AE) after pancreaticoduodenectomy (PD).MethodsThis study was conducted on a retrospective cohort of patients presenting biliopancreatic complications after PD from 01/01/2012 to 31/12/2022. All patients underwent ERCP at our Endoscopy Unit. Clinical, instrumental data, and characteristics of endoscopic treatments were collected.Results133 patients were included (80 M, mean age = 65 y.o.) with a total of 296 endoscopic procedures (median = 2 procedures/treatment). The indications for ERCP were mainly biliary AE (76 cases, 57.1%). Technical success was obtained in 121 patients of 133 (90.9%). 112 out of 133 (84.2%) obtained clinical success. Nine patients out of 112 (8%) experienced AEs. Clinical success rates were statistically different between patients with biliary or pancreatic disease (93.4% vs 73.6%, p < 0.0001). Septic patients were 38 (28.6%) and showed a worse prognosis than non-septic ones (clinical success: 65.7% vs 91.5%, p = 0.0001). During follow-up, 9 patients (8%), experienced recurrence of the index biliopancreatic disease with a median onset at 20 months (IQR 6–40.1).ConclusionOur case series demonstrated that the use of a pediatric colonoscope in ERCP procedures for patients with AEs after PD is both safe and effective in treating the condition, even in a long-term follow-up.

BackgroundMalignant Distal Biliary Obstruction (MBDO) is a common event occurring along the natural history of both pancreatic cancer and cholangiocarcinoma. Epidemiological and biological features make MBDO one of the key elements of the clinical management of patients suffering for of pancreatic cancer or cholangiocarcinoma. The development of dedicated biliary lumen-apposing metal stents (LAMS) is changing the clinical work up of patients with MBDO. i-EUS is an Italian network of clinicians and scientists with a special interest in biliopancreatic endoscopy, EUS in particular.MethodsThe scientific methodology was chosen in line with international guidance and in a fashion similar to those applied by broader scientific associations. PICO questions were elaborated and subsequently voted by a broad panel of experts within a simplified Delphi process.Results and conclusionsThe manuscripts describes the results of a consensus conference organized by i-EUS with the aim of providing an evidence based-guidance for the appropriate use of the techniques in patients with MBDO.

Non-celiac gluten sensitivity (NCGS) is characterized by the onset of symptoms after eating gluten-containing food. We aimed to single out NCGS subjects among subjects with functional gastrointestinal symptoms. Patients were enrolled in a multicenter double-blind placebo-controlled trial with crossover. Symptoms and quality of life were evaluated by means of 10-cm VAS and SF36. Iron parameters, transaminases and C reactive protein (CRP) were evaluated. After a three-week-long gluten-free diet (GFD), responsive patients were randomly assigned to gluten intake (5.6 g/day) or placebo for seven days, followed by crossover. The primary endpoint was the worsening of symptoms (VAS increase ≥3 cm) during gluten ingestion compared to placebo. One hundred and forty patients were enrolled and 134 (17 males, mean age 39.1 ± 11.7 years, BMI 22.4 ± 3.8) completed the first period. A total of 101 subjects (10 males, mean age 39.3 ± 11.0 years, BMI 22.3 ± 4.0) reported a symptomatic improvement (VAS score 2.3 ± 1.2 vs. 6.5 ± 2.2 before and after GFD, p = 0.001). 98 patients underwent the gluten challenge and 28 (all females, mean age 38.9 ± 12.7 years, BMI 22.0 ± 2.9) reported a symptomatic relapse and deterioration of quality of life. No parameters were found to be statistically associated with positivity to the challenge. However, 14 patients responded to the placebo ingestion. Taking into account this finding, about 14% of patients responding to gluten withdrawal showed a symptomatic relapse during the gluten challenge. This group is suspected to have NCGS.

Background Pancreatic leaks occur as a complication of upper gastrointestinal surgery, acute pancreatitis, or abdominal trauma. Pancreatic fistulas and leaks are primarily managed conservatively. Overall, conservative measures are successful in more than half of cases. Whenever conservative treatment is not efficient, surgery is usually considered the treatment of choice. Nowadays however, endoscopic treatment is being increasingly considered and employed in many cases, as a surgery sparing intervention. Aim To introduce a classification of pancreatic fistulas according to the location of the leak and ductal anatomy and finally propose the best suited endoscopic method to treat the leak according to current literature. Methods We performed an extensive review of the literature on pancreatic fistulae and leaks. Results In this paper, we review the various types of leaks and propose a novel endoscopic classification of pancreatic fistulas in order to standardize and improve endoscopic treatment. Conclusions A proper and precise diagnosis should be made before embarking on endoscopic treatment for pancreatic leaks in order to obtain prime therapeutic results. A multidisciplinary team of interventional endoscopists, pancreatic surgeons, and interventional radiologists is best suited to care for these patients.
