In this limited, first of its kind feasibility study, the computer-assisted colonoscope was shown to perform colonoscopy safely and effectively. The colonoscope's unique design limited loop formation during colonoscopy. Large-scale clinical trials are indicated.
The presence of a bile duct stenosis is significantly related to bile duct stone recurrence after treatment with LISL. The impact of the body mass index on stone recurrence is interesting. The gallbladder status did not predict stone recurrence in our study.
The intact gallbladder is not a risk factor for recurrent biliary complications after ESWL of common bile duct stones; therefore, as far as patients with complicated bile duct stones which require additional lithotripsy techniques are concerned, elective cholecystectomy after endoscopic clearance of the bile duct no longer seems appropriate.
Progression of ERD is an unlikely event. Once-in-lifetime endoscopy is an adequate screening tool that may serve as a basis for a Barrett's esophagus surveillance program.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
