OBJECTIVE To describe the use of argon plasma coagulation in the endoscopic treatment of eroded Marlex mesh. DESIGN Case report. SETTINGS Endoscopy Unit, University of Iowa Hospitals and Clinics, Iowa(More)
Endoscopic electronic medical record systems (EEMRs) are now increasingly utilized in many endoscopy centers. Modern EEMRs not only support endoscopy report generation, but often include features such as practice management tools, image and video clip management, inventory management, e-faxes to referring physicians, and database support to measure quality(More)
The close proximity of the endoscopic ultrasound probe to the pancreas results in superior spatial resolution compared to CT scan and MRI. In addition, endoscopic ultrasound (EUS) is a minimally invasive procedure that does not share the relatively high complication rate of ERCP. Due to these advantages, EUS has evolved into an important technique to assess(More)
INTRODUCTION Gastroparesis is a common chronic and costly disorder for which medical therapy is often unsuccessful. Gastric electrical stimulation (GES) has been used to treat refractory cases, however, response is variable and difficult to predict. This study aims to assess whether pre-operative opioid analgesics (OA) use affects clinical success of GES.(More)
UNLABELLED Colonic configuration during insertion phase (IP) and withdrawal phase (WP) is different and some polyps seen during IP are difficult to find during WP and vice versa. To determine if polypectomy performed during both IP and WP of colonoscopy (study arm) increases adenoma detection rate (ADR) compared to WP only (control arm). In this prospective(More)
OBJECTIVES Regulatory changes requiring the use of capnographic monitoring for endoscopic procedures using moderate sedation have placed financial challenges on ambulatory and hospital endoscopy centers across the United States due to the increased cost of training endoscopy personnel and purchasing both capnography-monitoring devices and specialized(More)
BACKGROUND EUS-guided Trucut biopsy (TCB) enables the acquisition of tissue cores for histologic assessment. Touch imprint cytology (TIC) can be performed at the time of a biopsy to assess the adequacy of the sample; however, limited information is available on the diagnostic value of TIC of these specimens. OBJECTIVE To investigate the diagnostic(More)
