We introduce visualization methods for augmented and virtual reality displays that guide minimally invasive tumor-targeting interventions, such as radio-frequency ablation (RFA). Our experimental RFA guidance system performs virtual ablations that geometrically match the real ablations in statically registered phantoms. It provides a head-tracked stereoscopic display that shows a real-time, mot...

As patients and their physicians become more demanding, the desire to make the procedures "minimally invasive" is growing constantly. In short, "minimally invasive" is a code phrase for life saving procedures which in same time disrupt our quality of life the least. Its goals include reducing incision size, decreasing surgical trauma and pain, and improving cosmesits, patient satisfaction, and ...

Traditionally, urologists recommend an interval of at least 4 weeks after prostate biopsy before radical prostatectomy. The aim of our study was to evaluate whether the interval from prostate biopsy to radical prostatectomy affects immediate operative outcomes, with a focus on differences in surgical approach. The study population of 1,848 radical prostatectomy patients was divided into two gro...

BACKGROUND AND OBJECTIVES To evaluate the feasibility of a minimally invasive approach for hysterectomy for benign disease at a university teaching hospital. METHODS Five hundred thirty-seven consecutive patients underwent hysterectomy for benign disease at Penn State Milton S. Hershey Medical Center in 2010. No cases were excluded. Minimally invasive approaches included total vaginal hystere...

Introduction Hemodynamic monitoring is typically performed to ensure tissue oxygenation in critically ill patients in different settings. Until recently the pulmonary artery catheter (PAC) was widely used for this task in order to assess cardiac output (CO), the primary determinant of oxygen delivery. Today, a variety of minimally invasive hemodynamic monitors are available decreasing the wides...

BACKGROUND Our working hypothesis was that minimally invasive surgery was superior to conventional surgery for total hip arthroplasty procedure. We compared THR results in the minimally invasive posterior approach with THR results in the conventional posterior approach. METHODS Prospective, randomised trial. Fifty patients were selected and then divided into two groups based on treatment (min...

Abstract Introduction Primary Hyperparathyroidism (PH) is common cause of hypercalcaemia (0.3% the population). Minimally invasive radio-guided parathyroidectomy (MIRP) has been made possible due to advancements in pre-operative imaging i.e. sestamibi scans allowing localisation areas parathyroid hyperactivity. Method Due disagreement literature regarding which intra operative adjunct best used...

Recognition of the significant advantages of minimizing surgical trauma has resulted in the development of minimally invasive surgical procedures. Endoscopic surgery offers patients the benefits of minimally invasive surgery, and surgical robots have enhanced the ability and precision of surgeons. Consequently, technological advances have facilitated totally endoscopic robotic cardiac surgery, ...
