BACKGROUND AND STUDY AIMS Reliable closure of the transluminal incision is the crucial step for natural orifice transluminal endoscopic surgery (NOTES) procedures. The aim of this study was to evaluate the feasibility and effectiveness of transgastric access closure with a flexible stapling device in a porcine survival model. PATIENTS AND METHODS We(More)
OBJECTIVE The aim of our study was to compare the age-standardized incidence of esophageal cancer (EC) in Puerto Ricans (PRs) with that for non-Hispanic White (NHW), non-Hispanic Black (NHB), and Hispanic (USH), groups in the United States (US) as reported by the Surveillance, Epidemiology, and End Results program for the 1992-2005 period. METHODS We(More)
BACKGROUND AND STUDY AIMS Creation of a submucosal cushion before endoscopic mucosal resection (EMR) significantly reduces perforation risk. We evaluated six solutions as cushioning agents in live pigs. MATERIAL AND METHODS 5 ml of normal saline, normal saline plus epinephrine, albumin 12.5 %, albumin 25 %, hydroxypropyl methylcellulose, and the pig's own(More)
CONTEXT The incidence of post-ERCP pancreatitis is 1-22%. It continues to be a difficult problem for endoscopist and patient. Uncovering an agent that may be used to prevent its occurrence is critical. OBJECTIVE The aim of our study was to investigate the role of etanercept in the prevention of post-ERCP pancreatitis. DESIGN Endoscopic retrograde(More)
BACKGROUND Ampullary adenomas are increasingly being recognized, particularly in patients with familial adenomatous polyposis. A capsule endoscopy (CE) is routinely recommended for surveillance of small-intestinal polyposis. Performance characteristics of CE for the detection of periampullary lesions are unclear. OBJECTIVE To evaluate the ability of CE to(More)
BACKGROUND AND STUDY AIMS Pancreatitis complicates 1% - 22% of endoscopic retrograde cholangiopancreatography procedures. The study aims were to develop a reproducible animal model of post-ERCP pancreatitis (PEP), and investigate the impact of endoscopic technique on severity of PEP. PATIENTS AND METHODS ERCP was carried out in six male hound dogs.(More)
Reliable closure of the translumenal incision is one of the main challenges facing natural orifice translumenal endoscopic surgery (NOTES). This study aimed to evaluate the use of an automated flexible stapling device (SurgASSIST) for closure of the gastrotomy incision in a porcine model. A double-channel gastroscope was advanced into the stomach. A gastric(More)
BACKGROUND Several designs of endoscopic clips are now commercially available, and the indications for endoclip application are rapidly expanding. However, very limited data have been published to aid in choosing between the different types of endoclips. OBJECTIVE To compare the duration of clip attachment between all commercially available endoclips. (More)
BACKGROUND Transluminal access site closure remains a major challenge in natural orifice transluminal endoscopic surgery (NOTES). OBJECTIVE Our purpose was to develop in vivo leak tests for evaluation of the integrity of transgastric access closure. SETTINGS Survival experiments on 12 50-kg pigs. DESIGN AND INTERVENTIONS After a standardized(More)
BACKGROUND & AIMS The suspected blood indicator (SBI) feature of wireless capsule endoscopy (WCE) was developed for rapid screening of intestinal lesions with bleeding potential. Our aim was to assess the accuracy and performance characteristics of the SBI according to the indications for study in a large cohort of patients. METHODS We reviewed collected(More)
