teaching polypectomy

Tingxi Wen, David Medveczky, Jackie Wu, Jianhuang Wu
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...

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...

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: 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...
