Safety of artificial intelligence-assisted optical diagnosis for leaving colorectal polyps in situ during colonoscopy (PRACTICE): a non-inferiority, randomised controlled trial.

Background: Guidelines recommend leaving in situ rectosigmoid polyps diagnosed during colonoscopy that are 5 mm or smaller if the endoscopist optically predicts them to be non-neoplastic. However, no randomised controlled trial has been done to examine the efficacy and safety of this strategy.

Methods: This open-label, multicentre, non-inferiority, randomised controlled trial enrolled adults age 18 years or older undergoing colonoscopy for screening, surveillance, or clinical indications across four Italian centres.

Clinical Outcome After Entero-Enteric Anastomosis for Crohn's Disease: A Case-Control Study.

Background And Aims: The outcome of Crohn's Disease (CD) patients with entero-enteric anastomosis (EEA) after small bowel resection is undefined. The primary aim of the present case-control study was to compare the clinical recurrence rate within the first 5 years after surgery in CD patients with small bowel EEA (Cases) versus age-matched patients with ileo-colonic anastomosis (ICA, Controls).

Methods: All CD patients with EEA were matched for age at diagnosis (±5years) and smoking habits with 2 Controls with ICA.

Endoscopic ultrasound-guided gallbladder versus bile duct drainage for first-line therapy of malignant biliary obstruction: international multicenter trial.

Background:  Endoscopic ultrasound (EUS)-guided gallbladder drainage (GBD) and EUS-guided choledochoduodenostomy (CDS) with lumen-apposing metal stents are alternative approaches to endoscopic retrograde cholangiopancreatography. We compared EUS-GBD and EUS-CDS as first-line therapies in the management of distal malignant biliary obstruction (MBO).

Methods:  This was an international, multicenter, retrospective, observational study at 28 tertiary care centers from April 2017 to August 2024.

Underwater versus standard endoscopic submucosal dissection for superficial colorectal neoplasms: a propensity score matched analysis.

Background And Study Aims: Underwater ESD (UESD) has recently emerged as a less complex technical alternative to standard endoscopic submucosal dissection (SESD), but only small retrospective data are currently available. Our aim was to evaluate the effectiveness and safety of UESD, as compared to the current standard of care.

Patients And Methods: We performed a 1-to-4 nearest-neighbor retrospective propensity-score-matched-analysis between all UESD cases and all SESD cases performed and collected prospectively in a Western and an Eastern interventional endoscopy referral center, respectively.

Impact of age and comorbidities on colorectal endoscopic submucosal dissection outcomes: Large multicenter study in a Western cohort.

Background And Study Aims: Endoscopic submucosal dissection (ESD) has emerged as the standard treatment for colorectal lesions. Considering aging of the global population, we aimed to assess effectiveness and safety of colorectal ESD in patients aged ≥ 80 years compared with those aged 65 to 79 years in a large Western cohort.

Patients And Methods: We retrospectively enrolled patients aged > 64 years undergoing colorectal ESD, classifying them into a very elderly group (VE-Group, aged > 80 years) and elderly group (E-Group, 65-79 years).

Malignant Bowel Occlusion: An Update on Current Available Treatments.

Malignant bowel obstruction (MBO) is a critical complication occurring in patients with advanced malignancy. Current treatments are both surgical and non-surgical, the latter including medical, endoscopic, and percutaneous approaches. Surgery is still the treatment of choice for MBO.

Development and validation of a risk score for incomplete resection during endoscopic papillectomy: PANETH score.

Objectives: Endoscopic papillectomy (EP) is the gold standard treatment for ampullary adenomas. However, EP is still burdened by a nonnegligible rate of incomplete resections (IR). Different predictors have been linked to higher rates of IR, but the interaction between these factors is still unclear.

Endoscopic Ultrasound-Guided Anastomoses of the Gastrointestinal Tract: A Multicentric Experience.

This multicenter retrospective study included patients undergoing EUS-guided GI anastomoses from 2016 to 2023. Indications for EUS-guided anastomosis were GOO, ALS or patients with altered anatomy needing endoscopic interventions. The primary outcome was technical success, while secondary outcomes included clinical success, safety, lumen-apposing metal stent (LAMS) patency, and the need for reinterventions.

Efficacy and safety of H-APC in Barrett's esophagus: Italian prospective multicenter study.

Background And Study Aims: Hybrid argon plasma coagulation (H-APC) is a novel technique for ablation of neoplastic Barrett's esophagus (BE), consisting in submucosal fluid injection and subsequent APC of visible BE. The aim of this study was to assess H-APC efficacy, safety, and tolerability.

Patients And Methods: We prospectively included patients undergoing H-APC ablation at four Italian Hospitals from September 2022 to March 2024.

Neuronal hyperactivity in neurons derived from individuals with gray matter heterotopia.

Periventricular heterotopia (PH), a common form of gray matter heterotopia associated with developmental delay and drug-resistant seizures, poses a challenge in understanding its neurophysiological basis. Human cerebral organoids (hCOs) derived from patients with causative mutations in FAT4 or DCHS1 mimic PH features. However, neuronal activity in these 3D models has not yet been investigated.

Outcomes of endoscopic submucosal dissection for high-risk colorectal colitis-associated neoplasia in inflammatory bowel disease.

Background:  Patients with inflammatory bowel disease (IBD) have an increased risk of colorectal cancer. High-risk colorectal colitis-associated neoplasia (HR-CAN) can be difficult to treat using traditional endoscopic resection methods. This study evaluated the outcomes of endoscopic submucosal dissection (ESD) in patients with IBD and HR-CANs.

Palliation of Gastric Outlet Obstruction in Case of Biliary Obstruction-A Retrospective, Multicenter Study: The B-GOOD Study.

Background: EUS-guided gastroenterostomy (EUS-GE) is a novel and effective procedure for the management of malignant gastric outlet obstruction (GOO) with more durable results when compared to enteral stenting (ES). However, data comparing EUS-GE to ES in patients already treated with EUS-guided choledocoduodenostomy (EUS-CDS) for distal malignant biliary obstruction (DMBO) are lacking. We aimed to compare outcomes of EUS-GE and ES for the palliation of GOO in this specific population of patients.

Endoscopic ultrasound-guided entero-colostomy with lumen-apposing metal stent as a rescue treatment for malignant intestinal occlusion: a multicenter study.

Background: Surgery is the first-choice treatment for malignant intestinal obstruction (MIO); however, many patients are deemed unfit for surgery. Endoscopic ultrasound-guided entero-colostomy (EUS-EC) with a lumen-apposing metal stent (LAMS) could represent a new treatment option.

Methods: Consecutive patients undergoing EUS-EC for MIO from November 2021 to September 2023 at four European tertiary referral centers were retrospectively enrolled.

Technical failure during colorectal endoscopic full-thickness resection: the "through thick and thin" study.

Background:  Endoscopic full-thickness resection (EFTR) is an effective and safe technique for nonlifting colorectal lesions. Technical issues or failures with the full-thickness resection device (FTRD) system are reported, but there are no detailed data. The aim of our study was to quantify and classify FTRD technical failures.
