Currently, no optimal curriculum exists for the Fundamentals of Laparoscopic Surgery (FLS) manual skills training program. The objective was to create a proficiency-based training curriculum that would allow both successful completion of the FLS manual skills exam and improved performance in the operating room. Two experienced laparoscopic surgeons(More)
Findings have shown that single-incision laparoscopic cholecystectomy (SILC) is feasible and reproducible. The authors have pioneered a two-trocar SILC technique at the University of Texas Southwestern. Their results for 100 patients are presented. From January 2008 to March 2009, 100 patients with symptomatic gallbladder disease underwent SILC through a(More)
BACKGROUND Routine cholecystectomy is often performed at the time of gastric bypass for morbid obesity. The aim of our study was to determine the incidence of gallstone formation requiring cholecystectomy following a laparoscopic Roux-en-Y gastric bypass (LRYGBP). METHODS 289 LRYGBP were performed between November 1999 and May 2002. 60 patients (21%) who(More)
The critical state of intensive care unit (ICU) patients demands close monitoring, and as a result a large volume of multi-parameter data is collected continuously. This represents a unique opportunity for researchers interested in clinical data mining. We sought to foster a more transparent and efficient intensive care research community by building a(More)
Natural orifice translumenal endoscopic surgery (NOTES) is an evolving field and suitable instruments are lacking. The purpose of this study was to perform transvaginal cholecystectomies using instruments incorporated into a magnetic anchoring and guidance system (MAGS). Non-survival procedures were conducted in pigs (n = 4). Through a vaginotomy created(More)
BACKGROUND The purpose of this study was to develop a performance-based laparoscopic suturing curriculum using simulators and to test the effectiveness (transferability) of the curriculum. STUDY DESIGN Surgical residents (PGY1 to PGY5, n = 17) proficient in basic skills, but with minimal laparoscopic suturing experience, were enrolled in an IRB-approved,(More)
OBJECTIVE The extent to which treatment modifies the excess in morbidity and mortality in acromegaly remains uncertain. This study investigates the determinants of final outcome following therapy for acromegaly. DESIGN A retrospective analysis of patients treated at the Departments of Endocrinology and Neurosurgery, Auckland Hospital, New Zealand. (More)
One of the benefits of Digital PCR (dPCR) is the potential for unparalleled precision enabling smaller fold change measurements. An example of an assessment that could benefit from such improved precision is the measurement of tumour-associated copy number variation (CNV) in the cell free DNA (cfDNA) fraction of patient blood plasma. To investigate the(More)
PURPOSE To measure the sensitivity and accuracy of double-contrast magnetic resonance (MR) imaging for the diagnosis of hepatocellular carcinoma (HCC) in the cirrhotic liver. MATERIALS AND METHODS Twenty-seven patients with MR features of dysplastic nodules and/or HCC were examined. T2-weighted spin-echo and T1-weighted gradient-echo imaging was performed(More)
Although case reports link proton-pump inhibitor (PPI) use and hypomagnesemia, no large-scale studies have been conducted. Here we examined the serum magnesium concentration and the likelihood of hypomagnesemia (<1.6 mg/dl) with a history of PPI or histamine-2 receptor antagonist used to reduce gastric acid, or use of neither among 11,490 consecutive adult(More)
