BACKGROUND AND AIMS: Endoscopic mucosal resection (EMR) is the primary treatment of large laterally spreading colonic lesions (LSL). Residual or recurrent adenoma (RRA) is a major limitation. We aimed to identify a robust method to stratify risk of RRA. METHODS: Prospective multicenter data on consecutive LSL ≥ 20mm removed by piecemeal EMR from eight Australian tertiary centers was included (September 2008 until May 2016). A logistic regression model for endoscopically determined recurrence (EDR) was created on a randomly selected half of the cohort to yield the Sydney EMR Recurrence Tool (SERT), a 4-point score to stratify the incidence of RRA based on characteristics of the index EMR...

BACKGROUND AND AIMS: EUS-guided transluminal drainage (EUS-TD) and sequential direct endoscopic necrosectomy (DEN) for pancreatic fluid collections (PFCs) using a dedicated biflanged metal stent (BFMS) has been reported as a useful alternative to using plastic stents or a conventional metal stent. However, current dedicated BFMSs have limitations. Recently, a new BFMS with solidly constructed biflanges and various stent lengths matched to the PFC condition has been developed. Herein, we prospectively evaluated this new BFMS for the treatment of PFCs...

BACKGROUND: Endoscopic submucosal tunneling dissection (ESTD) has been proved to be safe and effective for removal of esophageal submucosal tumors (SMTs) and can maintain the mucosal integrity compared with other endoscopic methods. The aim of the study was to estimate the safety and efficacy of ESTD as well as compare its efficacy with thoracoscopic enucleation for esophageal SMTs, which is used increasingly as a minimally invasive approach. METHODS: We retrospectively collected the clinical data of the patients with esophageal SMTs smaller than 40 mm who underwent ESTD or thoracoscopic enucleation at Nanfang hospital between January 2008 and August 2016...

BACKGROUND AND AIMS: Endoscopic submucosal dissection (ESD) is currently commonly performed, but colorectal ESD has a substantial risk of adverse events, including post-ESD electrocoagulation syndrome (PEECS). We investigated whether the use of prophylactic antibiotics can reduce the occurrence of PEECS. METHODS: Patients who underwent colorectal ESD were randomly assigned to 1 of 2 treatment regimens. Ampicillin/sulbactam mixed with normal saline solution was administered 1 hour before ESD in group I, and then additionally injected every 8 hours twice more...

BACKGROUND AND AIMS: Targeting neoplasia in Barrett's esophagus (BE) is challenging. Volumetric laser endomicroscopy (VLE) is a new imaging technique that allows for real time cross-sectional microstructure imaging that can detect BE neoplasia. The interobserver agreement among users in practice is unknown. METHODS: Eight high-volume users of VLE from different academic centers in the United States evaluated 120-stored VLE images blinded to the endoscopic and clinical findings...

BACKGROUND AND AIMS: OncoGel is paclitaxel (PTX) formulated in a thermosensitive, biodegradable copolymer for focused cytotoxicity and radiosensitization. A phase IIa study suggested EUS-guided PTX injection into esophageal tumors subsequently receiving radiation therapy (RT) was safe. METHODS: In an international multicenter, prospective randomized phase IIb study, patients with local or locoregional adenocarcinoma or squamous cell carcinoma (SCCA) of the esophagus/GE junction and eligible for neoadjuvant chemoradiotherapy (CRT) before surgery were randomized to standard of care (SOC) plus EUS-guided PTX injection or SOC alone...

BACKGROUND AND AIMS: Interval colorectal cancer (iCRC) incidence is the criterion standard benchmark for measuring the effectiveness of colonoscopy. Colonoscopy surveillance guidelines are designed to minimize iCRC cases. Our aims were to (1) describe characteristics of iCRC patients; and (2) assess if development of iCRC is related to colonoscopy surveillance guideline intervals. METHODS: We performed a retrospective cohort study of post-colonoscopy iCRC cases in a large healthcare system...

BACKGROUND AND AIMS: Recently a low-volume polyethylene glycol containing ascorbic acid (PEG-Asc) formulation has proven as safe and effective as traditional 4L PEG solutions for colonoscopy preparation. However, currently available aqueous purgative formulations are poorly tolerated. The aim of this study was to compare a split-dose 2L PEG-Asc and a 1L PEG-Asc with bisacodyl (10 mg) formulation to determine the quality of bowel cleansing and patient tolerability. METHODS: A single-center, randomized, observer-blinded study was performed between May 2015 and September 2015...

BACKGROUND AND AIMS: Endoscopy is performed with air insufflation and is usually associated with abdominal pain. It is well recognized that carbon dioxide (CO2) is absorbed more quickly into the body than air; however, to date, few studies have investigated the use of CO2 insufflation during consecutive esophagogastroduodenoscopy and colonoscopy (CEC). Thus, this study evaluated the efficacy of CO2 insufflation compared with air insufflation in CEC. METHODS: From March 2014 to April 2016, a total of 215 consecutive patients were randomly assigned to receive CO2 insufflation (CO2 group, n=108) or air insufflation (air group, n=107)...

BACKGROUND AND AIMS: Endoscopic therapy is the standard treatment for high-grade dysplasia and some cases of T1a esophageal adenocarcinoma (EAC), but it is not appropriate for deeply invasive disease. Data on the value of EUS for patient selection for endoscopic or surgical resection are conflicting. We investigated the outcome of esophageal EUS for the staging and treatment selection of patients with treatment-naïve, premalignant Barrett's esophagus (BE) and suspected superficial EAC...

BACKGROUND & AIMS: Among the greatest hurdles to pancreatic cancer (PC) therapy is the limited tissue penetration of systemic chemotherapy due to tumor desmoplasia. The primary study aim was to determine the toxicity profile of EUS-guided fine-needle injection (EUS-FNI) with gemcitabine. Secondary endpoints included ability to disease downstage leading to a R0 resection, and overall survival at 6 months, 12 months, and 5 years after therapy. PATIENTS AND METHODS: In a prospective study from a tertiary referral center, gemcitabine (38mg/ml) EUS-FNI was performed in PC patients before conventional therapy...

BACKGROUND & AIMS: Multi-target stool DNA testing (MT-sDNA) is now FDA-approved for average-risk CRC screening. Trials leading to its approval used blinded colonoscopy as the reference standard. In the post-approval screen setting, the clinical performance and impact of MT-sDNA on unblinded colonoscopy has not been described. We measured the impact that knowledge of a positive MT-sDNA test result has on colonoscopy yield and quality. METHODS: The unblinded group comprised all patients with positive MT-sDNA results on screening from 9/1/14-9/30/15 at a single tertiary center...

BACKGROUND AND AIMS: Recent advances in endoscopic equipment and diagnostic techniques have made possible the detection of early dysplasia in the inflamed mucosa of ulcerative colitis (UC). The SCENIC consensus statement recommends the use of unified terminology for the morphology of dysplasia. In this study, we investigated the endoscopic features of high-grade dysplasia (HGD) in a clinical setting. METHODS: We retrospectively identified 62 patients with UC who were diagnosed with colitis-associated cancer or HGD between 1997 and 2015...

BACKGROUND AND AIMS: We investigated endocytoscopy (EC) findings that were considered risk factors for colorectal neoplasms and determined whether they could be used as new indices to identify carcinomas with massive submucosal invasion (SM-m) or worse outcomes. METHODS: We performed a multivariate analysis of 8 factors on EC images to determine whether they were associated with SM-m or worse. Based on the results, we divided the EC3a category of the EC classification into low grade or high grade, and investigated the diagnostic accuracy of this subclassification...
