PURPOSE: Outcomes of radical prostatectomy are prone to publication bias, because most of the data originated from highly specialized centers. We assessed in-hospital outcomes of all radical prostatectomies in Germany from 2006 to 2013 focusing on caseload volume, surgical approach, and certification status. METHODS: We analyzed the nationwide German hospital billing data covering 221,331 radical prostatectomies from 2006 to 2013. Outcomes were in-hospital mortality, surgical revision, and transfusion rates and the length of stay...

REVIEW
Fabio C M Torricelli, Joao Arthur B A Barbosa, Giovanni S Marchini
Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve...

Kara L Watts, Richard Ho, Reza Ghavamian, Nitya Abraham
INTRODUCTION AND HYPOTHESIS: High vesicovaginal fistulas (VVF) in the setting of good apical support are best repaired via a transabdominal approach. Laparoscopic VVF repair was first reported in 1998. Several series of robot-assisted VVF repairs have since been published. The robot-assisted approach allows repair of high apical vaginal fistulas while avoiding the morbidity of laparotomy, shortening convalescence, and facilitating the use of omental interposition flaps. This video presents the technique for robot-assisted extravesical VVF repair utilizing a laparoscopically mobilized omental flap...

Robot-assisted surgery on a broad front - without evidence for being cost-effective Robot-assisted surgery is currently heavily marketed. The HTA centre in Region Västra Götaland has produced five HTA reports regarding use of robot-assisted surgery in different clinical situations (prostatic cancer, benign gynaecological surgery, pediatric pyeloplasty and fundoplication, and rectal cancer), finding weak evidence for a patient value. The current report by Per Carlsson et al confirms that robot-assisted surgery indeed leads to increased costs that are not balanced by augmented patient value, i...

BACKGROUND: It is very important for robotically assisted minimally invasive surgery to achieve a high-precision and smooth motion control. However, the surgical instrument tip will exhibit vibration caused by nonlinear friction and unmodeled dynamics, especially when the surgical robot system is attempting low-speed, fine motion. METHODS: A fuzzy neural network sliding mode controller (FNNSMC) is proposed to suppress vibration of the surgical robotic system. Nonlinear friction and modeling uncertainties are compensated by a Stribeck model, a radial basis function (RBF) neural network and a fuzzy system, respectively...

Due to the urgent need for high precision surgical equipment for minimally invasive spinal surgery, a novel robot-assistant system was developed for the accurate placement of pedicle screws in lumbar spinal surgeries. The structure of the robot was based on a macro-micro mechanism, which includes a serial mechanism (macro part) and a bi-planar 5R parallel mechanism (micro part). The macro part was used to achieve a large workspace, while the micro part was used to obtain high stiffness and accuracy. Based on the transfer function of dimension errors, the factors affecting the accuracy of the end effectors were analyzed...

BACKGROUND: Although there is no agreement on a definition of elderly, commonly an age cutoff of ≥65 or 75 years is used. Nowadays most of malignancies requiring surgical treatment are diagnosed in old population. Comorbidities and frailty represent well-known problems during and after surgery in elderly patients. Minimally invasive surgery offers earlier postoperative mobilization, less blood loss, lower morbidity as well as reduction in hospital stay and as such represents an interesting and validated option for elderly population...
