While neck dissection is an important primary and adjunctive procedure in the treatment of head and neck cancer, there is a paucity of studies evaluating outcomes. A retrospective review of the National Surgical Quality Improvement Program (NSQIP) database was performed to identify factors associated with adverse events (AEs) in patients undergoing neck dissection. A total of 619 patients were identified, using CPT codes specific to neck dissection. Of the 619 patients undergoing neck dissection, 142 (22.9%) experienced an AE within 30 days of the surgical procedure...

The aim of this study is to identify optimal patients for adjuvant radiation therapy (ART) in pT3 prostate cancer. The role of ART for patients with adverse pathologic features after radical prostatectomy (RP) has been demonstrated, but over- or under-treatment remains a significant concern. Two-hundred and five patients with pT3N0M0 who underwent robot-assisted RP without ART were analyzed. Multivariate Cox proportional regression analyses were used to identify predictors of biochemical recurrence (BCR) and clinical progression (CP)...

OBJECTIVES: Successful kidney transplant depends partly on the normal physiologic functioning of the bladder, which involves effective urine storage and emptying. The bladder may become abnormal owing to various urologic and neuropathic disorders. Patients with abnormal bladders need careful management before and after transplant. In this study, we aimed to determine the outcomes of renal transplants in relation to various causes of abnormal bladder. MATERIALS AND METHODS: We conducted a retrospective review of 25 patients with abnormal bladder who received 30 renal transplants between 1990 and 2014...

Dexterous continuum manipulators (DCMs) offer great potential for increasing instrument reach in minimally-invasive surgical procedures. We previously designed and fabricated a tendon driven DCM with a large instrument channel and evenly distributed compliant joints for minimally-invasive skull base surgery and the treatment of osteolysis during hip revision surgery. The evenly distributed compliant joints, in some cases, may limit the reach of the DCM during lesion removal. In this paper, we propose a finite element analysis (FEA) method for optimizing the distribution of the compliant joints based on treatment space requirements determined preoperatively...

BACKGROUND: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has been the "gold standard" for weight loss surgery. Long-term data are limited, and reporting methods for LRYGB outcomes vary in the literature. In addition, follow-up compliance within bariatric centers is poor due to insurance and access to care issues, making long-term follow-up evaluation difficult. OBJECTIVE: Evaluate long-term LRYGB outcomes using standard outcome reporting definitions. SETTING: Integrated multispecialty health system...

OBJECTIVE: Presurgical language assessment can help minimize damage to eloquent cortex during resective epilepsy surgery. Two methods for presurgical language mapping are functional MRI (fMRI) and direct cortical stimulation (DCS) of implanted subdural electrodes. We compared fMRI results to DCS to help optimize non-invasive language localization and assess its validity. METHODS: We studied 19 patients referred for presurgical evaluation of drug-resistant epilepsy...
