The rapid development and deployment of novel laparoscopic instruments present the surgical educator and trainee with a significant challenge. Several useful instruments have been particularly difficult to teach the novice. We have developed a platform that allows the combination of the actual instrument handle with a virtual re-creation of the instrument tip. We chose the Autosuture Endo Stitch device as the prototypical instrument because it satisfies our subjective experience of "useful, but hard to teach." A software package was developed to support the re-creation of the needle and suture that accompany the device. The apparatus has haptic capabilities and collision detection so that the needle driver is "aware" of suture and instrument contact. The developed virtual environment allows re-creation of the necessary motion to simulate the instrument, the trainee can use the actual instrument handle, and the system can be altered to accommodate other instruments.

Introduction: The aim of this retrospective study was to evaluate the impact of stapling devices use on overweight and obese bladder cancer patients treated with radical cystectomy (RC).
Materials And Methods: Fifty-two overweight and 24 obese patients underwent open RC for muscle invasive bladder cancer. Bladder removal was performed using standard suture technique (SST) or multifire autosuture articulated vascular Endo-GIA (eG).
Ultrastructural analysis of different-made staplers' staples.

Aim: Recently, Chinese-made mechanical staplers with lower price respect to American-made ones have been introduced in clinical practice. In literature, small case series compare the clinical outcomes of different staplers concluding that the new stapler devices perform as well as the American ones. The aim of this study is to compare with an ultrastructural analysis the staples of different staplers in order to verify the existence of differences that might explain significant price disparity and condition clinical outcomes.

Objectives/hypothesis: The purpose of this study is to review a consecutive series of patients with Zenker's diverticulum who were treated with endoscopic diverticulostomy using either the endoscopic stapler (ENDO GIA 30 Autosuture; Covidien, Dublin, Ireland) or Harmonic Ultrasonic Surgical Instrumentation (Ethicon Endo-Surgery, Cincinnati, OH) to evaluate the safety and optimal application of Harmonic technology to the treatment of patients with Zenker's diverticulum.
Study Design: This is a retrospective review at a tertiary academic hospital with institutional review board approval.
Methods: All patients undergoing endoscopic repair of Zenker's diverticulum between April 1, 2009 and December 1, 2010 at a single institution were studied.

Objectives: To compare effectiveness in terms of blood loss and operative time of stapling devices among surgeons with different levels of surgical volume.
Methods: We evaluated a group of 29 male patients with invasive bladder cancer who underwent radical cystectomy by two groups of surgeons. The first group included two high-volume surgeons, and the second group two low-volume surgeons.
