Pilot study on a new endoscopic platform for colorectal endoscopic submucosal dissection.

Background: The endoscopic submucosal dissection (ESD) is a technically demanding and time-consuming procedure, with an increased risk of adverse events compared to standard endoscopic resection techniques. The main difficulties are related to the instability of the operating field and to the loss of traction. We aimed to evaluate in a pilot trial a new endoscopic platform [tissue retractor system (TRS); ORISE, Boston scientific Co.

Feasibility and safety of a new dedicated biliary stent for EUS-guided hepaticogastrostomy: The FIT study (with video).

Background And Objectives: EUS-guided biliary drainage (BD) through hepaticogastrostomy (HGS) is an option in case of ERCP failure. Available data suggest that this procedure may be challenging with possible severe adverse events (AEs) mainly due to stent migration. The aim of our pilot study was to prospectively assess the technical and clinical outcomes of EUS-HGS using a new dedicated partially covered self-expandable metal stent with anti-migratory systems.

Endoscopic submucosal dissection for colorectal neoplasia: outcomes and predictors of recurrence.

The role of endoscopic submucosal dissection (ESD) for colorectal lesions in Western communities is unclear and its adoption is still limited. The aim of this study is to assess the long-term outcomes of a large cohort of patients treated with colorectal ESD in a tertiary Western center. A retrospective analysis was conducted on patients treated by ESD for superficial colorectal lesions between February 2011 and November 2019.

Cap-Assisted Endoscopic Septotomy of Zenker's Diverticulum: Early and Long-Term Outcomes.

Introduction: Multiple therapeutic modalities including surgery and rigid and flexible endoscopy have been adopted to manage Zenker's diverticulum (ZD). Minimally invasive flexible endoscopic septotomy (FES) techniques have been increasingly favored over the past 20 years; however, long-term data are still scanty. The aim of this study is to evaluate early and long-term outcomes of FES for naive ZD in a single-center setting.

Flexible endoscopic treatment for Zenker's diverticulum: from the lumen to the third space.

Zenker's diverticulum (ZD) is a rare outpouching of the esophageal mucosa herniating posteriorly through Killian's triangle. Treatments of ZD aim to dissect the cricopharyngeal muscle to remove the underlying dysfunctional condition. In the last decade, a septotomy performed utilizing a flexible endoscope has been reported as a safe and effective alternative to both open surgery and rigid endoscopic diverticulotomy.

Risk of Covert Submucosal Cancer in Patients With Granular Mixed Laterally Spreading Tumors.

Background And Aims: Granular mixed laterally spreading tumors (GM-LSTs) have an intermediate level of risk for submucosal invasive cancer (SMICs) without clear signs of invasion (covert); the optimal resection method is uncertain. We aimed to determine the risk of covert SMIC in GM-LSTs based on clinical and endoscopic factors.

Methods: We collected data from 693 patients (50.

Coronavirus (COVID-19) outbreak: what the department of endoscopy should know.

Italy recorded its first case of confirmed acute respiratory illness because of coronavirus on February 18, 2020, soon after the initial reports in China. Since that time, Italy and nations throughout the world have adopted very stringent and severe measures to protect populations from spread of infection. Despite these measures, the number of infected people is growing exponentially, with a significant number of patients developing acute respiratory insufficiency.

Cost analysis and outcome of endoscopic submucosal dissection for colorectal lesions in an outpatient setting.

Background And Study Aims: Endoscopic submucosal dissection (ESD), a minimally invasive treatment for early gastrointestinal (GI) cancer, is considered challenging and risky in the colorectum. As such, most patients undergoing ESD are hospitalized due to the perceived increased risk of adverse events. The aim of this study was to compare the costs, safety and efficacy of colorectal-ESD in an outpatient vs inpatient setting in a tertiary level center.

Self-Expanding Metal Stents for the Treatment of Post-Surgical Esophageal Leaks: A Tertiary Referral Center Experience.

Background/aims: The study aimed to evaluate the effectiveness and safety of self-expanding metal stents (SEMS) in the management of post-surgical esophageal leaks.

Methods: Retrospective data of consecutive patients with a post-surgical esophageal leak treated by means of a metal stent between January 2008 and December 2014 at the Humanitas Research Hospital (Milan, Italy) were extracted from a prospectively maintained register of SEMS used for benign indications, such as post-surgical benign esophageal strictures and/or leaks. The primary outcome of the study was to assess the rate of successful leak closure and to identify the variables associated with its achievement.

Endoscopic Management of Benign Esophageal Ruptures and Leaks.

Esophageal leaks (EL) and ruptures (ER) are rare conditions associated with a high risk of mortality and morbidity. Historically, EL and ER have been surgically treated, but current treatment options also include conservative management and endoscopy. Over the last decades, interventional endoscopy has evolved as an effective and less invasive alternative to primary surgery in these cases.

Natural history and management of refractory benign esophageal strictures.

Background And Aims: The natural history of refractory benign esophageal strictures (RBES) is unclear, and surgery or percutaneous endoscopic gastrostomy (PEG) may be the only viable long-term options. The aim of the present study was to assess the long-term outcomes of patients with RBES.

Methods: Clinical data of consecutive patients with RBES treated in the previous 15 years in 2 tertiary-care referral academic centers with specialized interest in esophageal stricture management were retrospectively analyzed.

Endo-sponge therapy for management of anastomotic leakages after colorectal surgery: A case series and review of literature.

Background: Endo-sponge treatment is a novel approach to manage selected patients with anastomotic leakage following colorectal surgery. However, the available data are still scanty.

Aims: To evaluate the efficacy and safety of the endo-sponge therapy in a large series, and to perform a review of the current evidence concerning such a treatment.

Timing of antibiotic prophylaxis in acute pancreatitis: a controlled randomized study with meropenem.

Objectives: Antibiotic prophylaxis improves the outcome of acute pancreatitis. Since bacterial translocation from the gut occurs in the first h of disease, early therapy is likely to achieve the maximal effect. The study compares early antibiotic treatment with treatment started after the demonstration of pancreatic necrosis.
