Comparative Study
A human factors analysis of technical and team skills among surgical trainees during procedural simulations in a simulated operating theatre.
High-risk organizations such as aviation rely on simulations for the training and assessment of technical and team performance. The aim of this study was to develop a simulated environment for surgical trainees using similar principles. ⋯ The simulated operating theatre could serve as an environment for the development of surgical competence among surgical trainees. Objective, structured, and multimodal assessment of performance during simulated procedures could serve as a basis for focused feedback during training of technical and team skills.

We sought to quantitatively and objectively evaluate histomorphologic tumor regression and establish a relevant prognostic regression classification system for esophageal cancer patients receiving neoadjuvant radiochemotherapy. ⋯ Histomorphologic tumor regression and lymph node status (ypN) were significant prognostic parameters for patients with complete resections (R0) following neoadjuvant radiochemotherapy for esophageal cancer. A regression classification based on 2 parameters could lead to improved objective evaluation of the effectiveness of treatment protocols, accuracy of staging and restaging modalities, and molecular response prediction.

Randomized Controlled Trial Multicenter Study Comparative Study
Efficacy of sacral nerve stimulation for fecal incontinence: results of a multicenter double-blind crossover study.
This is the first double-blind multicenter study examining the effectiveness of sacral nerve stimulation in a significant number of fecally incontinent patients. ⋯ The significant improvement in FI during the ON versus OFF period indicated that the clinical benefit of sacral nerve stimulation was not due to placebo.

Randomized Controlled Trial Comparative Study
Fibrin sealant versus mechanical stapling for mesh fixation during endoscopic extraperitoneal inguinal hernioplasty: a randomized prospective trial.
To compare the clinical outcome of simultaneous bilateral endoscopic totally extraperitoneal inguinal hernioplasty (TEP) using fibrin sealant (FS) and mechanical stapling for prosthetic mesh fixation. ⋯ This randomized prospective clinical trial demonstrated a significant reduction of analgesic consumption by using FS for mesh fixation during bilateral TEP, but it was associated with an increased incidence of postoperative seroma.

Comparative Study
Simultaneous pancreas-kidney transplantation from donation after cardiac death: successful long-term outcomes.
The outcomes of simultaneous pancreas-kidney (SPK) transplantation with donor organs procured from donation after cardiac death (DCD) are compared with transplants performed with donor organs recovered from donation after brain death (DBD). ⋯ SPK transplantation using selected DCD donors is a safe and viable method to expand the organ pool for transplantation.
