Laparoscopic Radical Prostatectomy: The Learning Curve of a Low Volume Surgeon

OBJECTIVE Analyze the learning curve for laparoscopic radical prostatectomy in a low volume program. MATERIALS AND METHODS A single surgeon operated on 165 patients. Patients were consecutively divided in 3 groups of 55 patients (groups A, B, and C). An enhancement of estimated blood loss, surgery length, and presence of a positive surgical margin were all considered as a function of surgeon'...

Re: The Surgical Learning Curve for One-Stage Anterior Urethroplasty: A Prospective Single-Surgeon Study.

BACKGROUND The learning process for one-stage anterior urethroplasty has never been addressed before. OBJECTIVE To evaluate the surgical learning curve for one-stage anterior urethroplasty. DESIGN, SETTING, AND PARTICIPANTS Data from 641 consecutive patients treated with one-stage urethroplasty for urethral stricture were collected prospectively. All the procedures were performed by a singl...

Surgeon Volume in Parathyroid Surgery-Surgical Efficiency, Outcomes, and Utilization.

OBJECTIVES/HYPOTHESIS To test our hypothesis that high-surgeon volume is associated with improved surgical efficiency and 30-day outcomes, and lower hospital utilization. STUDY DESIGN Retrospective observational cohort, 2008-2013. METHODS A total of 3,135 patients with hemithyroidectomy or total thyroidectomy performed by a high-volume surgeon, propensity score-matched to 3,135 patients wit...

The single surgeon learning curve of laparoscopic liver resection

The aim of the study was to evaluate the single-surgeon learning curve (SSLC) in laparoscopic liver surgery over an 11-year period with risk-adjusted (RA) cumulative sum control chart analysis.Laparoscopic liver resection (LLR) is a challenging and highly demanding procedure. No specific data are available for defining the feasibility and reproducibility of the SSLC regarding a consistent and c...
