OBJECTIVE.We evaluated the safety and efficacy of using a 14-gauge Tru-Cut needle without imaging guidance vs using an 18-gauge Biopty gun with sonographic guidance for percutaneous biopsy of kidney transplants. MATERIALS AND METHODS. We retrospectively analyzed data from 105 biopsies (in 68 patients) in which the Biopty gun with an 18-gauge needle was used and data from 100 biopsies (in 64 patients) in which a 14-gauge Tru-Cut needle was used.RESULTS. Significantly fewer major complications (p = .03) occurred when the
The use of laparoscopic US for the accurate evaluation of the CBD and biliary anatomy requires that the surgeon has surpassed the learning curve, which we have defined as having performed >10 US exams.
High resolution computed tomography (CT) was used to scan the wrists of 19 patients with idiopathic carpal tunnel syndrome. Thirteen normal volunteers were used as controls. Measurements obtained from the CT images included the cross-sectional area of the carpal tunnel, the relative amount of synovium within the carpal tunnel, the attenuation coefficient of the carpal tunnel, and the thickness of the transverse carpal ligament. No significant difference in any of these measurements was found when comparing the wrists of symptomatic patients with controls. High resolution CT of the wrist does not appear to be of value in the preoperative evaluation of patients with idiopathic carpal tunnel syndrome.
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.
