BACKGROUND AND AIMS: Malignant vascular invasion usually results from gross direct infiltration from a primary tumor, and impacts cancer staging, prognosis, and therapy. However, patients may also develop a remote malignant thrombi (RMT), defined as a malignant intravascular thrombus located remote and noncontiguous to the primary tumor. Our aim was to compare the endoscopic ultrasound (EUS) and the computed tomography (CT) and magnetic resonance imaging (MRI) findings of RMT and impact on cancer staging and resectability...

BACKGROUND: The American Society for Gastrointestinal Endoscopy recommends that distal colon hyperplastic lesions can be left in place without resection if adenomatous histology can be excluded with > 90% negative predictive value. However, some of the lesions could be sessile serrated adenoma/polyp (SSA/P), which is also precancerous. AIM: Describe the prevalence of SSA/P in hyperplastic appearing diminutive rectosigmoid polyps. METHODS: We prospectively placed 513 consecutive diminutive rectosigmoid polyps that appeared hyperplastic to an expert endoscopist in individual bottles for pathologic examination...

BACKGROUND: and study aim: Endoscopic submucosal dissection (ESD) is a useful method for complete resection of early gastric cancer (EGC). However, there are still some cases that underwent additional gastrectomy after ESD because of non-curative resection. There is no model that can accurately predict non-curative resection of ESD. We aimed to create a model for predicting non-curative resection of ESD in patients with EGC. PATIENTS AND METHODS: We reviewed the medical records, including all gross findings of EGC, of patients who underwent ESD for EGCs...

BACKGROUND AND AIMS: To elucidate the efficacy of pancreatic juice cytology with the cell block method (CB-PJC) for the determination of surgery in patients with branch duct intraductal papillary mucinous neoplasm (BD-IPMN). METHODS: In 138 patients with BD-IPMN from whom pancreatic juice was collected under ERCP for CB-PJC, we retrospectively evaluated the following: (1) the rate of the CB-PJC successfully evaluated, (2) the ability of CB-PJC for the diagnosis of malignant BD-IPMNs and for the identification of pathological subtypes in resected BD-IPMNs, (3) the rate of development into invasive cancer and progression of BD-IPMNs in patients with BD-IPMN diagnosed as benignancy by CB-PJC, and (4) post-ERCP adverse events...

BACKGROUND AND AIMS: The recent development of endosonography (EUS)-guided gallbladder drainage (EGBD) with a lumen-apposing stent has made endoscopic assessment and advanced gallbladder interventions via the stent possible. The aim of this study was to assess the feasibility and safety of per-oral cholecystoscopy and the types of gallbladder interventions that can be performed. METHODS: This was a retrospective review conducted in the Prince of Wales Hospital from June 2012 to March 2016...

BACKGROUND: Per-oral endoscopic myotomy (POEM) has become an accepted treatment for patients with achalasia. Despite its excellent efficacy rate of greater than 80%, a small percentage of patients remain symptomatic postprocedure. Limited data exist as to the best management for recurrence of symptoms after POEM. We present the first international, multicenter experience on the efficacy and safety of a repeat POEM in the management of achalasia. METHODS: Patients who underwent a redo POEM from 15 centers in 9 countries were included in a dedicated registry...

BACKGROUND: Classification schemes for differentiation of conventional colorectal adenomas from serrated lesions rely on patterns of blood vessels and pits. Morphologic features have not been validated as predictors of histology. AIM: Describe the prevalence of the "valley sign" and validate it as a marker of conventional adenomas METHODS: Three experts judged the prevalence of the valley sign in 301 consecutive small adenomas. Medical students were taught to recognize the valley and tested on their recognition of the valley sign...

BACKGROUND AND AIMS: Extensive excision of the esophageal mucosa by endoscopic submucosal dissection (ESD) frequently evokes a luminal stricture. This study aimed to determine the efficacy of a high-density collagen patch for the prevention of esophageal stricture in extensive ESD. METHODS: Six pigs underwent circumferential esophageal ESD under general anesthesia. In 3 pigs, artificial ulcers were covered by 2 collagen patches. The other 3 pigs underwent circumferential ESD only...

BACKGROUND AND AIMS: Although the number of gastric cancer patients aged ≥85 years indicated for endoscopic submucosal dissection (ESD) has increased, little is known about their outcomes and prognostic factors. This study aimed to investigate the clinical outcomes and factors prognostic of overall survival (OS) of patients aged ≥85 years who underwent ESD for gastric cancer. METHODS: We retrospectively reviewed 108 patients aged ≥85 years with 149 gastric cancers treated by ESD between 1999 and 2014 at our institution...

BACKGROUND AND AIMS: Endoscopist fatigue may impact colonoscopy quality, but prior studies conflict, and minimal data exist from community-based practices where most colonoscopies are performed. METHODS: Within a large, community-based integrated healthcare system, we evaluated the associations among 4 measures of endoscopist fatigue and colonoscopic adenoma detection during the years 2010 to 2013. Fatigue measures included afternoon versus morning colonoscopy and the number of GI procedures performed before a given colonoscopy, including consideration of prior procedure complexity...

BACKGROUND AND AIMS: Surveillance programs of patients with head and neck cancer (HNC) detect synchronous or metachronous esophageal squamous cell carcinoma (ESCC) in up to 15% of the patients. Non-invasive probe-based confocal laser endomicroscopy (pCLE) technique may improve the diagnosis allowing acquisition of high-resolution in vivo images at the cellular and microvascular levels. The aim was to evaluate the accuracy of pCLE for the differential diagnosis of non-neoplastic and neoplastic Lugol-unstained esophageal lesions in patients with HNC...
