Objective: To evaluate health system use, health outcomes, and avoided costs when patients with chronic gastrointestinal (GI) conditions are managed in the medical home.
Design: A retrospective, observational cohort study was conducted through a single-point-of-entry referral system.
Setting: Calgary, Alta.

Background And Aims: Endoscopic treatment is a definitive and cost-effective management strategy for early neoplasia in Barrett's oesophagus (BE). However, little is known of its impact on quality of life (QoL). This study reports outcomes of endoscopic eradication treatment (EET), focusing on QoL and costs in a Canadian tertiary referral centre.

After initial reports of high efficacy, there has been an increasing recognition of variability in the effectiveness of CADe systems. The aim of this study was to evaluate a CADe system in a varied colonoscopy population.

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.

We conducted a systematic study with this aim.
Methods: All experiments were performed in an porcine gastrointestinal tract model.
Background: According to guidelines, all visible lesions in Barrett's esophagus (BE) should be endoscopically resected. Available methods of endoscopic resection include the cap-assisted technique and, more recently, multiband mucosectomy (MBM). Data on the efficacy and safety of MBM have yet to be systematically reviewed.
View Article and Find Full Text PDFBackground And Aims: Peroral endoscopic myotomy (POEM) has been recommended for achalasia treatment. To prevent the potential of infective risk, antibiotic prophylaxis is usually administered, whereas the additional need of antibiotic therapy after POEM is uncertain. The primary endpoint was to determine whether prophylaxis versus prophylaxis plus short therapy was needed after POEM.

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.

Methods: Data from the National Ambulatory Medical Care Survey were used to estimate annual rates and associated costs of ambulatory visits for symptomatic irritable bowel syndrome, chronic functional abdominal pain, constipation, or diarrhea.
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.
Background: Treatments of Zenker's diverticulum aim to dissect the cricopharyngeal muscle, removing the underlying source of dysfunction. This is difficult in patients with a short-septum (≤ 20 mm) diverticulum because the limited anatomical space restricts the operating area for either rigid or flexible endoscopic approaches. The aim of this study was to investigate the efficacy and safety of a novel third-space approach, peroral endoscopic septotomy (POES), for treating symptomatic patients with short-septum Zenker's diverticulum.
View Article and Find Full Text PDFBackground: Endoscopic retrograde cholangio-pancreatography (ERCP) is commonly performed in the management of pancreatic and biliary disease. Duodenoscopes are specialized endoscopes used to perform ERCP, and inherent to their design, a high rate of persistent bacterial contamination exists even after automated reprocessing and disinfection. Consequently, in recent years, ERCP has been associated with infection transmission, leading to several fatal patient outbreaks.
View Article and Find Full Text PDFBackground And Aims: Endoscopic sphincterotomy (ES) with stone extraction is the standard treatment for choledocholithiasis. After stone retrieval, balloon-occluded cholangiography is generally performed to confirm bile duct clearance but can miss residual stones particularly in patients with residual small-sized stones, a large bile duct or pneumobilia. In addition, difficult common bile duct (CBD) stones requiring advanced endoscopic techniques for retrieval are a potential risk factor for choledocholithiasis recurrence.

Core biopsies of the left supraclavicular lymph node showed squamous cell carcinoma, which required differentiation between secondary and primary pancreatic neoplasms. Endoscopic ultrasound-guided sampling using a novel fine needle biopsy system was key to making a definite histological diagnosis and determining the best treatment plan.
View Article and Find Full Text PDFBackground: As endoscopic ultrasound-guided tissue acquisition techniques evolve, there is increasing interest in obtaining optimal histological samples to improve diagnostic accuracy. In this study, we aimed to assess the tissue acquisition success rate and test performance characteristics of a novel endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) system.
Methods: We performed a retrospective review of consecutive patients undergoing EUS-guided tissue sampling of solid lesions using the SharkCore fine needle system in a tertiary referral facility.
Background And Study Aims: It is unclear to what extent EUS influences the surgical management of patients with pancreatic adenocarcinoma. This systematic review sought to determine if EUS evaluation improves the identification of unresectable disease among adults with pancreatic adenocarcinoma.
Patients And Methods: We searched MEDLINE, EMBASE, bibliographies of included articles and conference proceedings for studies reporting original data regarding surgical management and/or survival among patients with pancreatic adenocarcinoma, from inception to January 7th 2017.

Objective: To determine the incidence of gastrointestinal (GI) bleeding in patients after cardiac surgery, assess the perioperative risk factors, and determine the type of GI tract pathology associated with bleeding events.
Methods: At a tertiary referral hospital, all cardiac surgery patients having a postoperative GI bleed from April 2002 to March 2012 were identified. To determine bleeding etiology, only patients requiring endoscopy were included in the analysis.
