BACKGROUND: Hiatal hernias are common. In some reports, hiatal hernias have been implicated in causing dyspnea, syncope, and heart failure. CASE PRESENTATION: An 82-year-old woman with a hiatal hernia was admitted to our hospital because she had experienced postprandial syncope during the last few years. Esophagogastroduodenoscopy revealed a large hiatal hernia and a pedunculated polyp of the stomach antrum that fit into the pylorus. An upper gastrointestinal contrast study showed that the entire stomach had relocated to the thoracic cavity and that the body of the stomach was located above the fundus, resulting in a so-called upside-down stomach...

OBJECTIVES: Although large polyps are known to harbor more advanced neoplasia than small polyps, the extent of the relationship between size and type is not fully known. The study aim was to establish benchmarks for the prevalence of different histologic polyp types among varying size categories. METHODS: The Miraca Life Sciences Database is an electronic repository of histopathologic patient records from private practices throughout the United States. We extracted the records of 483,998 unique patients who underwent colonoscopy with polypectomy between January 2008 and December 2014...

OBJECTIVE: We present the case of a 57-year-old man with a history of Roux-en-Y gastric bypass (RYGB) and colonic polyps who presented with an upper gastrointestinal obstruction based on massive stomach polyposis in the pouch. METHODS: Two months prior to this acute admission, he had undergone resection of the gastric remnant due to massive refractory intraluminal bleeding from a polypoid mass. Ten years earlier, right colectomy was performed due to hypertrophic polyposis unsuitable for endoscopic polypectomy...

Gastrointestinal (GI) schwannoma is one of the rarest tumors of the GI tract. We herein describe the case of a 70-year-old female patient who presented for surveillance colonoscopy. The examination detected a 1-cm polyp that was removed by snare cautery polypectomy. Immune and histochemical staining revealed spindle cells that were positive for S-100 and vimentin, but negative for CD34 and smooth muscle actin, consistent with GI schwannoma. This case is noteworthy as GI schwannomas usually present in the stomach, making the finding of a colonic schwannoma of clinical interest...

TEAD4 (TEA domain family member 4) was recently revealed as an oncogenic character in tumorigenesis. However, its role remains unclear in colorectal tumorigenesis. Here, we firstly found that the expression level of TEAD4 was significantly elevated in clinical samples of colorectal adenomas (CRA) and correlated with the size and histological type of CRA. Moreover, patients with higher TEAD4 expression in normal colon mucosa are more prone to be recurrent after polypectomy. TEAD4 knockdown significantly inhibited colorectal cell proliferation in vitro and suppressed tumor growth in vivo...

BACKGROUND AND AIMS: The optimal technique for the resection of sessile serrated polyps (SSPs) is unknown, with established limitations and risks with conventional polypectomy. Although cold snare polypectomy is safe, the efficacy of piecemeal resection for large lesions is untested. In this study, we evaluate the safety and efficacy of cold endoscopic mucosal resection (EMR) for large SSPs. METHODS: Patients presenting for elective colonoscopy at an academic endoscopy center with 1 or more SSPs ≥10mm in size were enrolled, excluding those on anticoagulants or antiplatelets other than aspirin...

BACKGROUND: Colorectal cancer is a leading cause for cancer-related mortality. Adenomatous polyps are typically resected endoscopically to prevent cancer while giant and complex polyps are managed surgically. No criteria clearly define the indications for surgical versus endoscopic resection. AIM: To evaluate factors associated with short-term efficacy and safety of endoscopic resection of large (≥20mm) and giant (≥40mm) adenomas. METHODS: Consecutive cases with colonic adenomas larger than 20mm, resected endoscopically were included...

REVIEW
Maurice B Loughrey, Neil A Shepherd
Two issues commonly arise for pathologists reporting adenomatous polyps of the colorectum. Particularly problematic within large sigmoid colonic adenomas is the distinction between benign misplacement of epithelium into the submucosa and invasive malignancy. This distinction requires careful morphologic evaluation of key discriminatory features, assisted only rarely by the application of selected adjunctive immunohistochemistry. Following a diagnosis of adenocarcinoma within a polypectomy or other local excision specimen, systematic assessment is required of features that may indicate the risk of residual local and/or nodal neoplastic disease and inform management decision-making regarding the need for further endoscopic or surgical intervention...

BACKGROUND AND AIMS: Patients with spinal cord injury (SCI) suffer significant morbidity from neurogenic bowel. Chronic constipation has long-been a proposed risk factor for polyp development. We performed a retrospective cohort study in veterans with SCI to assess polyp presence in the setting of colonic stasis. METHODS: All consecutive patients at the James A. Haley Veterans Affairs Hospital with SCI and neurogenic bowel who completed screening colonoscopy between January 1, 2004 to June 30, 2013 were included...

Chemoprevention is a practical approach to reduce the risk of various cancers including colorectal cancer (CRC). The goal is to reduce the incidence of pre-neoplastic adenomatous polyps and prevent its progression to CRC. Curcumin and silibinin prevent intestinal polyp formation in mice. Curcumin sensitizes silymarin to exert synergistic anticancer activity in colon cancer cells. Patients presenting with multiple colorectal adenomatous polyps (MCRA) have a high lifetime risk for CRC. We present a 57-year-old man with MCRA, without deleterious germline APC or MYH mutations...

Colon perforation is a very serious complication of colonoscopy. The correct diagnosis and management of therapy improve the prognosis of patients. The treatment can be conservative, endoscopic and surgical. In this case report we present microperforation as a complication of polypectomy in the caecum during colonoscopy, followed by laparoscopic surgery.Key words: colonoscopy - complication -perforation polypectomy.

INTRODUCTION: Linked-color imaging (LCI) is a recently developed system used in endoscopy. It creates clear and bright endoscopic images using short-wavelength, narrow-band laser light combined with white laser light. The illuminating light and signal processing emphasize slight color differences in abnormal regions that approximate the normal color of the mucosa. As a result, regions initially appearing red become a deeper shade of red, while regions originally appearing white become brighter, yet with natural tones...

Introduction Colonoscopy trainers have gained recognition for improving endoscopy skills and preparing for real procedures on humans. Unfortunately, due to their high price, commercial simulators are hard to obtain, especially for small medical centers. However, a solution might be to construct a device for themselves. Aim Our goal was to build a relatively cheap and easy-to-construct simulator for residents who want to start learning colonoscopy. Materials and methods The box model colonoscopy trainer was designed and constructed...

BACKGROUND AND AIMS: Large sessile/flat colonic polyps are traditionally removed by lift polypectomy. Underwater endoscopic mucosal resection (UEMR) is a novel technique where air is suctioned out and replaced by water to decompress the colon so that the flat lesions assumes a more polypoid shape facilitating its removal with the standard snare resection. We report the feasibility and safety in our series of patients utilizing this technique. PATIENTS AND METHODS: A retrospective, observational study of all patients who underwent removal of large colonic polyps (>10 mm) over a period of 3 years (January 2012 - January 2015) at a tertiary care center by UEMR were included in the study...

BACKGROUND AND AIMS: The U.K. guidelines for risk stratification after colon polypectomy differ from the U.S. guidelines in 2 ways: the U.K. guidelines consider ≥5 adenomas as high risk and do not consider histology (villous or high-grade dysplasia) in the assessment. Thus, we aimed to investigate the risk of advanced colorectal neoplasm (CRN) by categorized risk groups, considering both ≥5 adenomas and histology. METHODS: A total of 2570 patients with ≥1 adenoma at index colonoscopy were included...

BACKGROUND: Sessile serrated polyps (SSPs) are associated with higher rates of incomplete resection compared to conventional adenomas after traditional snare polypectomy. Outcomes after endoscopic mucosal resection (EMR) are less established. The aim of this study was to evaluate the rate of residual neoplasia at surveillance colonoscopy for SSPs compared to conventional adenomas ≥ 10 mm after en bloc EMR. METHODS: Retrospective cohort study of consecutive patients referred for EMR of a colonic lesion ≥ 10 mm from 2005 to 2013...

Histological features of colorectal lesions are currently evaluated via a magnifying chromoendoscopy [pit pattern (PIT) classification]. Advanced histological features are rarely observed in diminutive (≤5 mm) adenomatous polyps (DAPs). The Japanese guidelines indicate that diminutive neoplastic lesions without carcinomatous findings may be left untreated and followed up. At the present institution, DAPs with type IIIL PIT are left untreated in various cases, whereas lesions with type III, IV or V PIT are typically resected via routine colonoscopy...

BACKGROUND AND AIMS: Inadequate polypectomy leads to incomplete resection, interval colorectal cancer, and adverse events. However, polypectomy competency is rarely reported, and quality metrics are lacking. The primary aims of this study were to assess polypectomy competency among a cohort of gastroenterologists and to measure the correlation between polypectomy competency and established colonoscopy quality metrics (adenoma detection rate and withdrawal time). METHODS: We conducted a prospective observational study to assess polypectomy competency among 13 high-volume screening colonoscopists at an academic medical center...
