teaching polypectomy

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: The goal of this study is to examine utilization of early repeat colonoscopy ≤ 6 months after an index procedure. METHODS: We identified persons having repeat colonoscopy ≤ 6 months following outpatient colonoscopy without prior colonoscopy ≤ 5 years or prior diagnosis of colorectal cancer (CRC). We modeled repeat colonoscopy using a generalized estimating equation with an exchangeable correlation structure to account for clustering of patients by endoscopist...

OBJECTIVE: To estimate the positive predictive value of Pipelle endometrial sampling in detecting the presence of an underlying endometrial polyp. The secondary objective is to examine the histologic features that can predict the presence of endometrial polyps. STUDY DESIGN: This is a retrospective case review study. 195 women who had undergone diagnostic hysteroscopy and/or polypectomy were identified in a University teaching hospital. All patients had a prior polyp diagnosis in the Pipelle endometrial sample...

BACKGROUND/AIM: Increased demand for colon cancer screening procedures can significantly impact on routine colonoscopy management at dedicated facilities, prompting a review of the factors that can negatively affect workflow. Although potential adverse effects and impact on costs of deep sedation have been documented elsewhere, this study focuses on variables that can influence performance of colonoscopy in deep sedation and interfere with normal procedure scheduling in settings where the presence of an anesthesiologist is mandatory...

BACKGROUND: Paediatric endoscopy performed by adult gastroenterologists is a service delivery model that increases the access of children to endoscopy in countries where paediatric gastroenterologists with endoscopy skills are scarce. However, studies on the usefulness of this model in Nigeria and Sub-Saharan Africa are scarce. We aimed to evaluate the indications, procedures, diagnostic yield and safety of paediatric endoscopy performed by adult gastroenterologists in a Nigerian tertiary health facility...

OBJECTIVES/HYPOTHESIS: Office-based procedures have been proposed for the treatment of vocal polyps, including indirect laryngoscopic surgery and angiolytic laser photocoagulation. Our previous report documented good treatment outcomes by combining the two aforementioned procedures. This study was intended to further compare the treatment outcomes of office transnasal vocal fold polypectomy (VFP) with those of microlaryngoscopic surgery (MLS). STUDY DESIGN: A matched cohort study...

OBJECTIVES: The management of complex colorectal polyps varies in practice. Accurate descriptions of the endoscopic appearance by using a standardized classification system (Paris classification) and size for complex colon polyps may guide subsequent providers regarding curative endoscopic resection vs. need for surgery. The accuracy of this assessment is not well defined. Furthermore, the factors associated with decisions for endoscopic vs. surgical management are unclear. To characterize the accuracy of physician assessment of polyp morphology, size, and suspicion for malignancy among physician subspecialists performing colonoscopy and colon surgery...

BACKGROUND: Colonoscopic perforation (CP) has a low incidence rate. However, with the extensive use of colonoscopy, even low incidence rates should be evaluated to identify and address risks. Information on CP is quite limited in China. OBJECTIVE: Our study aimed to determine the frequency of CP in colonoscopies performed by surgeons at a large teaching hospital in China over a 12-year period. METHODS: A retrospective review of medical records was performed for all patients who had CPs from 1 January 2000 to 31 December 2012...

The aim of this study was to establish if there are any symptoms which can predict increased patient satisfaction following Endoscopic Sinus Surgery (ESS) and whether these symptoms correlate with Lund-Mackay score on Computerised Tomography (CT). A prospective observational study was performed. Ninety-three consecutive patients who were offered ESS were recruited from an otolaryngology department in a UK Teaching Hospital. All patients had failed medical therapies for chronic rhinosinusitis (CRS), recurrent acute sinusitis and/or nasal polyposis...

STUDY OBJECTIVE: To evaluate the usefulness of clinical, ultrasonographic, hysteroscopic, and immunohistochemical parameters in differentiating endometrial polyps from endometrial cancer. DESIGN: Cross-sectional study (Canadian Task Force classification II-2). SETTING: Tertiary public hospital, university teaching center. PATIENTS: Eighty-two women who underwent hysteroscopic polypectomy and 20 women who underwent surgery to treat endometrial cancer...

BACKGROUND: Colorectal cancer (CRC) is the second most common malignancy in Germany. Screening colonoscopies with polypectomy have been demonstrated to reduce the incidence of CRC. Detailed recommendations on scheduling screening and follow-up colonoscopies have therefore been included into national guidelines. Knowledge about CRC guidelines and adherence to guideline recommendations varies greatly among physicians. METHODS: We combined different implementation strategies (training courses, case discussion, handouts, wall charts) to improve adherence of recommendations for scheduling follow-up colonoscopy...

IMPORTANCE: Vocal polyps are common exophytic laryngeal lesions that usually necessitate microscopic laryngeal surgery under general anesthesia. Office-based indirect laryngoscopic procedures provide an alternative management option and can be performed comfortably under flexible endoscopic guidance. Combining angiolytic potassium titanyl phosphate (KTP) laser treatment and flexible endoscopic polypectomy should alleviate the risks of surgery under general anesthesia and expedite lesion regression...

The purpose of this study is to evaluate the current practice of Dutch gynecologists in the removal of benign endometrial polyps and compare these results with the results of a previous study from 2003. In 2009 Dutch gynecologists were surveyed by a mailed questionnaire about polypectomy. Gynecologists answered questions about their individual performance of polypectomy: setting, form of anesthesia, method, and instrument use. The results were compared with the results from the previous survey. The response rate was 70% (585 of 837 gynecologists)...

BACKGROUND: Proficiency and competence of endoscopists is perhaps the mainstay of successful diagnostic and therapeutic colonoscopy. AIM: To analyze indications, diagnostic findings, and complications of colonoscopies performed by resident physicians in a university teaching hospital. METHODS: Were analyzed 1,000 colonoscopies consecutively performed by fourth-year residents under direct supervision of experienced colonoscopists. Information on patients' demographic data, bowel preparation, indications for the procedure, success of the procedure, diagnostic findings, and complications were obtained...

UNLABELLED: Endoscopic removal of colon polyps is the main tool in colorectal cancer prevention programs. Although several quality indicators and guidelines have been proposed, polypectomy practices are still subject to great variation among endoscopist and little data is available regarding polypectomy practices in real life settings. METHODS: The records of the 1061 screening colonoscopies performed in 2010 in a tertiary care teaching hospital in Bucharest were reviewed and all colonoscopies where at least one polyp was detected were selected for analysis...

BACKGROUND: Following polypectomy, colectomy is performed selectively to ensure complete clearance of neoplasia. OBJECTIVE: This study aimed to determine the risk factors associated with residual disease at colectomy following malignant polypectomy. DESIGN: This is a retrospective study. SETTING: This investigation took place at a tertiary teaching cancer center. PATIENTS: Consecutive patients undergoing polypectomy followed by colectomy from 1990 to 2007 were identified from a prospective database...

BACKGROUND: The growing demand for colonoscopies and inappropriate colonoscopies have become a significant problem for health care.

To compare the results of the European Panel of Appropriateness of Gastrointestinal Endoscopy (EPAGE) and the EPAGE-II criteria. DESIGN: Cross-sectional study. SETTING: Endoscopy unit of a teaching hospital in Spain...

OBJECTIVES: To evaluate the significance of P53 and Ki-67 expression as immunohistochemical markers in early detection of premalignant changes in different types of colorectal adenomas. Also, to correlate immunohistochemical expression of the two markers with different clinicopathological parameters including; age, and sex of the patient, type, site, size and grade of dysplasia of colorectal adenomas. METHODS: Forty-seven polypectomy specimens of colorectal adenomas were retrieved from the archival materials of the Gastrointestinal and Hepatic Diseases Teaching Hospital in Baghdad from 2009 - 2010...

BACKGROUND: Informed consent is a phrase often used in the law to indicate that the consent a person gives meets certain minimum standards. It relies on patients' ability to understand risk information. Evidence suggests that people may extract the gist of any risk information to make medical decisions. Existing evidence also suggests that there is an inverse relationship between the perception of risk and the perception of benefit. Informed consent is the method by which fully informed, rational persons may be involved in choices about their health care...

BACKGROUND: Colonic endoscopic submucosal dissection (ESD) has developed in recent years to permit en bloc resection of larger colorectal lesions that cannot be done by standard polypectomy or mucosal resection techniques. Colonic ESD is technically demanding and has a steep learning curve. Adequate training is essential to make ESD a reliable treatment for colorectal neoplasms. We aim to share our early experience with an in vitro porcine training model for colonic ESD. METHOD: Resected porcine distal colon was used to set up a training model for ESD, which was performed as in human using a standard endoscope and dissecting devices...
