PURPOSE OF REVIEW: The purpose of this review is to summarize the management of serrated colorectal polyps (SPs), with a particular focus on the most common premalignant SP, sessile serrated adenoma or polyp (SSA/P). These lesions present a challenge for endoscopists with respect to detection and resection, and are also susceptible to pathologic misdiagnosis. RECENT FINDINGS: Patients with SSA/Ps are at an increased risk of future colorectal neoplasia, including advanced polyps and cancer...

Background/Aims: Colonoscopic surveillance is currently recommended after polypectomy owing to the risk of newly developed colonic neoplasia. However, few studies have investigated colonoscopy surveillance in Asia. This multicenter and prospective study was undertaken to assess the incidence of advanced adenoma based on baseline adenoma findings at 3 years after colonoscopic polypectomy. Methods: A total of 1,323 patients undergoing colonoscopic polypectomy were prospectively assigned to 3-year colonoscopy surveillance at 11 tertiary endoscopic centers...

BACKGROUND: Endoscopic resection of all colonic adenomas prevents the occurrence of colon cancer and death. The European Society of Gastrointestinal Endoscopy Clinical Guideline recommends resection of all polyps predicted to be adenomas and cold snare polypectomy (CSP) for removal of adenomas ≤ 9 mm on the basis of safety; however, it also states that this recommendation lacks adequate evidence of efficacy. The residual adenoma rate after resection is an important indicator of efficacy, but there have been no reports showing this prospectively...

REVIEW
Fadi H Mourad, Rupert W Leong
Despite the recent advances in endoscopic hemostatic techniques, the management of lower gastrointestinal bleeding could be sometimes challenging. Hemostatic powders such as hemospray, endoclot and Ankafred Blood Stopper have found their way into digestive endoscopy and are licenced in many countries especially for use in upper gastrointestinal bleeding. We reviewed the literature on the use of these hemostatic powders in different situations in lower gastrointestinal bleeding and looked at the success rate and rebleeding rate...

Introduction: Patients with inflammatory bowel disease (IBD) undergoing polypectomy are recommended by current guidelines to have biopsies taken from adjacent mucosa to determine whether there is dysplasia present. With improvements in endoscopic imaging it is now possible to characterise colonic lesions with higher levels of confidence than previously. We reviewed the diagnostic yield of polyp-adjacent biopsies in IBD. Materials and Methods: A systematic search of our histopathology database revealed cases where polyps had been endoscopically resected or biopsied in patients with IBD...

BACKGROUND: Colonoscopy plays an important role in the clinical screening and management of colorectal cancer. The traditional 'see one, do one, teach one' training style for such invasive procedure is resource intensive and ineffective. Given that colonoscopy is difficult, and time-consuming to master, the use of virtual reality simulators to train gastroenterologists in colonoscopy operations offers a promising alternative. METHODS: In this paper, a realistic and real-time interactive simulator for training colonoscopy procedure is presented, which can even include polypectomy simulation...

BACKGROUND: Colonoscopy is the gold standard for colorectal screening and surveillance. Advanced endoscopic polypectomy techniques such as endoscopic submucosal dissection (ESD) have been introduced to remove large colorectal polyps. Our aim was to compare the outcomes of patients who underwent ESD with those of who underwent laparoscopic colectomy for benign colorectal polyps. METHODS: Patients with a preoperative diagnosis of benign colorectal polyp who underwent ESD or colectomy between 2011 and 2016 were case matched for age, sex, body mass index, American Society of Anesthesiologists status, polyp size, and location...

Gastric heterotopia of the intestinal tract can have a diverse clinicopathologic presentation, resulting in a diagnostic dilemma. We present a series of four cases, two male and two female patients with age range of 31-82 year, found in the duodenum, jejunum, and transverse colon. The most common and rather unusual clinical presentation was iron deficiency anemia, seen in three cases, while one patient presented with abdominal pain. Endoscopically two cases were visualized as pedunculated polyps and two as sessile/plaques like lesions...

Background/Aims: Because of the national screening program for colorectal carcinoma in The Netherlands, the number of colonoscopies has increased. In case of incomplete colonoscopy, computed tomography colonography (CTC) and double-balloon colonoscopy (DBc) are alternative options. This study evaluated cecal intubation rate and pathology detection rate in the previously unexplored part of the colon, complication rate of DBc, and CTC results after incomplete colonoscopy. Methods: Retrospective observational study in a tertiary referral hospital regarding DBc and CTC reports from cases with incomplete colonoscopy...

PUPRPOSE: Benign polyps that are technically challenging and unsafe to remove via polypectomy are known as complex polyps. Concerns regarding safety and completeness of resection dictate they undergo advanced endoscopic techniques, such as endoscopic mucosal resection or surgery. We provide a comprehensive overview of complex polyps and current treatment options. METHODS: A review of the English literature was conducted to identifyarticles describing the management of complex polyps of the colon and rectum...

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...

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...
