Thickness of Cadaveric Human Lung Tissue.

Background: Choosing the correct surgical staple height is dependent on knowledge of specific tissue thickness and compressibility. The purpose of this study was to measure the thickness of cadaveric human lung tissue.

Materials And Methods: Between December 2012 and February 2013, whole lungs were procured from 12 donors.

Gastrectomy and D2 Lymphadenectomy for Gastric Cancer: A Meta-Analysis Comparing the Harmonic Scalpel to Conventional Techniques.

The ultrasonic Harmonic scalpel has demonstrated clinical and surgical benefits in dissection and coagulation. To evaluate its use in gastrectomy, we conducted a systematic review and meta-analysis of randomized controlled trials comparing the Harmonic scalpel to conventional techniques in gastrectomy for patients with gastric cancer. International databases were searched without language restrictions for comparisons in open or laparoscopic gastrectomy and lymphadenectomy.

Surgical stapling device-tissue interactions: what surgeons need to know to improve patient outcomes.

The introduction of both new surgical devices and reengineered existing devices leads to modifications in the way traditional tasks are carried out and allows for the development of new surgical techniques. Each new device has benefits and limitations in regards to tissue interactions that, if known, allow for optimal use. However, most surgeons are unaware of these attributes and, therefore, new device introduction creates a "knowledge gap" that is potentially dangerous.

Device-tissue interactions: a collaborative communications system.

Medical devices, including surgical staplers, energy-based devices, and access enabling devices, are used routinely today in the majority of surgical procedures. Although these technically advanced devices have proved to be of immense benefit to both surgeons and patients, their rapid development and continuous improvement have had the unintended consequence of creating a knowledge gap for surgeons due to a lack of adequate training and educational programs. Thus, there is an unmet need in the surgical community to collect existing data on device-tissue interactions and subsequently develop research and educational programs to fill this gap in surgical training.

Costs and clinical outcomes of conventional single port and micro-laparoscopic cholecystectomy.

Background And Objective: This study compares hospital costs and clinical outcomes for conventional laparoscopic, single-port, and mini-laparoscopic cholecystectomy from US hospitals.

Methods: Eligible patients were aged ≥18 years and undergoing laparoscopic cholecystectomy with records in the Premier Hospital Database from 2009 through the second quarter of 2010. Patients were categorized into 3 groups-conventional laparoscopic, single port, or mini-laparoscopic-based on the International Classification of Diseases, Ninth Revision and Current Procedural Terminology codes and hospital charge descriptions for surgical tools used.

Electromagnetic energy sources in surgery.

The biophysics, mechanism of actions, applications, benefits and complications of electromagnetic (EM) energy-based surgical instruments, and their current use are reviewed. Understanding the mechanism of action, tissue effects, and appropriate applications of EM devices is critical to achieving an optimal surgical outcome. Although a more diverse range of EM devices are used in human medicine, current use in veterinary medicine is limited to conventional electrosurgery and CO(2) lasers.
