INTRODUCTION: Due to its technical ease and greater precision Robotic Assisted Laparoscopic radical Prostatectomy (RALP) allows a better preservation of the neurovascular bundles, thereby improving functional outcomes. The intrafascial dissection has been proposed to allow a more complete preservation of these bundles. However, this technique harbors a high rate of positive surgical margins, justifying another trend: the interfascial approach. To date, there are still few publications directly comparing these 2 techniques and our study is the first to offer a 2-year follow-up...

OBJECTIVE: Literature showed the impact of surgical margin status on prognosis after radical prostatectomy (mostly on biochemical survival). Margin status is an easy self-evaluation of surgical practice to assess. The aim of this paper was to define what a positive surgical margin (PSM) is and how to prevent the occurrence, to precise the impact on survival and how to treat. METHOD: A literature analysis with Pubmed has been performed to 2012, furthermore conclusions of the main congresses with selection committee and review publication have also been studied...

BACKGROUND: Laparoscopic spleen-preserving Splenic hilar lymphadenectomy (LSPL) is required in laparoscopy-assisted total gastrectomy for advanced proximal gastric cancer. However, it is considerably difficult and risk in clinical practice. Thus, we explore the application of LSPL performed by following the perigastric fascias and the intrafascial space in D2 radical gastrectomy for advanced upper-third gastric cancer. METHODS: From July 2010 to December 2012, 109 patients with T2-3 upper-third gastric cancer underwent LSPL...

PURPOSE OF REVIEW: Although cure of prostate cancer is the primary goal of radical prostatectomy, preserving erectile function is also tantamount, given the indolent clinical course of most prostate cancers, particularly low-risk disease. In order to optimize postprostatectomy erectile function during a robotic-assisted radical prostatectomy, there must be a detailed understanding of pelvic anatomy to recognize the optimal nerve-sparing plane and technical finesse to minimize stretch injury to the neurovascular bundle...

The preservation of sexual potency after radical prostatectomy has always been the topic of much anxiety and debate. While cancer control and urinary continence are of supreme importance, the preservation of sexual function completes the trifecta that both patient and surgeon strive to achieve. The introduction of robotic assistance to modern laparoscopic surgery has provided many advantages, the two greatest being improved three-dimensional magnified vision and wristed instrumentation. These technical enhancements provide the surgeon with improved surgical tools that have the potential to facilitate a more precise surgical approach...

INTRODUCTION: Few studies have examined the patient characteristics that lead to early continence after robot-assisted radical prostatectomy (RARP), and to date, there has been no investigation into the predictors of immediate continence. In the current study, we examine a large multisurgeon population of patients undergoing RARP to assess for predictors of this outcome. PATIENTS AND METHODS: Between January 2008 and December 2010, 1270 patients who underwent RARP at our institution, with complete preoperative and follow-up data, were assessed for urinary function prospectively...

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Incremental nerve-sparing techniques (NSTs) improve postoperative erectile function after robot-assisted radical prostatectomy (RARP). However, there are no studies to date that histologically confirm the surgeon intended NST. Thus, in the present study, we histologically confirmed that the surgeon performed the nerve preservation as his intended NSTs during RARP. Also, we found that there was more variability in fascia width outcome on the left side compared with the right...

PURPOSE: To introduce and evaluate our open antegrade radical prostatectomy (ARP) technique, a nerve-sparing technique which offers patients better postsurgical urinary continence by our technique of 'Veil of Aphrodite'. METHODS: Ninety consecutive bilateral nerve-sparing ARPs performed using the Veil technique (intrafascial dissection) were compared to control ARP cases using non- or unilateral nerve sparing. Correlation of urinary continence with immunohistochemical (IHC) stains of nerves (S-100) around the prostate capsule was investigated in 20 consecutive patients whose ARPs were performed by a single surgeon...

INTRODUCTION: Improved visualization and magnification in robot-assisted laparoscopic radical prostatectomy (RALRP) has tempted many urologists to dissect the neurovascular bundle closer to the prostate following the layers of the pseudo-capsule of the prostate. This might bear a higher risk of decreased tumor control. MATERIALS AND METHODS: An analysis of a consecutive series of 186 patients who underwent RALRP at our institution was performed. The outcome of patients with intrafascial nerve-sparing (INS) was compared with the outcome of patients who underwent interfascial, extrafascial or no nerve-sparing (non-INS)...
