Comparison of Kinect and Leap Motion for Intraoperative Image Interaction.

Touchless interaction devices have increasingly garnered attention for intraoperative imaging interaction, but there are limited recommendations on which touchless interaction mechanisms should be implemented in the operating room. The objective of this study was to evaluate the efficiency, accuracy, and satisfaction of 2 current touchless interaction mechanisms-hand motion and body motion for intraoperative image interaction. We used the TedCas plugin for ClearCanvas DICOM viewer to display and manipulate CT images.

Effects of a Virtual Pointer on Trainees' Cognitive Load and Communication Efficiency in Surgical Training.

We investigated the cognitive load effect of a trainer providing surgical instruction by pointing/drawing over laparoscopic video to a trainee. Results showed that while cognitive load is higher overall with the use of the instructional system, there is a decrease by the second experience of being instructed by the Virtual Pointer. Further analysis showed that trainees were more likely to perform the surgical task and watch/listen to the trainer's instruction at the same time when the instructional system was used.

Virtual pointer for gaze guidance in laparoscopic surgery.

Background: A challenge of laparoscopic surgery is learning how to interpret the indirect view of the operative field. Acquiring professional vision-understanding what to see and which information to attend to, is thereby an essential part of laparoscopic training and one in which trainers exert great effort to convey. We designed a virtual pointer (VP) that enables experts to point or draw free-hand sketches over an intraoperative laparoscopic video for a novice to see.

A virtual pointer to support the adoption of professional vision in laparoscopic training.

Purpose: To assess a virtual pointer in supporting surgical trainees' development of professional vision in laparoscopic surgery.

Methods: We developed a virtual pointing and telestration system utilizing the Microsoft Kinect movement sensor as an overlay for any imagine system. Training with the application was compared to a standard condition, i.

Intraoperative "Micro Breaks" With Targeted Stretching Enhance Surgeon Physical Function and Mental Focus: A Multicenter Cohort Study.

Objective: The aim of this study was to investigate the effect of intraoperative targeted stretching micro breaks (TSMBs) on the experienced pain and fatigue, physical functions, and mental focus of surgeons.

Background: Surgeons are routinely subject to mental and physical stresses through the course of their work in the operating room. One of the factors most contributory to the shortening of a surgeon's career is work-related pain and its effects on patient safety and personal relationships.

Potential Operating Room Fire Hazard of Bone Cement.

Approximately 600 cases of operating room (OR) fires are reported annually. Despite extensive fire safety education and training, complete elimination of OR fires still has not been achieved. Each fire requires an ignition source, a fuel source, and an oxidizer.

Porcine acellular dermal matrix (PADM) vascularises after exposure in open necrotic wounds seen after complex hernia repair.

Biological alternatives to synthetic meshes are increasingly utilised in complex abdominal wall reconstruction. There is a lack of evidence demonstrating that non-cross-linked porcine acellular dermal matrix vascularizes and integrates with human tissue in suboptimal wound conditions. We aimed to evaluate these properties in Strattice™ (Life Cell Inc.

Raising the quality of hernia care: Is there a need?

Introduction: With a focus on raising the quality of hernia care through creation of educational programs, SAGES formed the Hernia Task Force (HTF). This study used needs assessment survey to target opportunities for improving surgical training and thus patient outcomes and experience.

Methods: This qualitative study included structured interviews and online surveys of key stakeholders: HTF members, surgeons, nurses, patients, hospital administrators, healthcare payers and medical suppliers.

A modified approach to component separation using biologic graft as a load-sharing onlay reinforcement for the repair of complex ventral hernia.

Background: Components separation has been proposed as a means to close large ventral hernia without undue tension. We report a modification on open components separation that allows for the incorporation of onlaid noncrosslinked porcine acellular dermal matrix (Strattice, LifeCell Corp, Branchburg, NJ) as a load-sharing structure.

Methods: This was a retrospective case series including all cases using Strattice from July 2008 through December 2009.

Mental and physical impact of body contouring procedures on post-bariatric surgery patients.

Objective: The rapid rate of weight loss following bariatric surgery leads to areas of excessive skin that can cause physical ailments and distortion of body image. Dissatisfaction with the excessive skin can lead patients to seek plastic surgery. This study aims to assess the changes in mental and physical quality of life after body contouring procedures in the post-bariatric surgery population.

Prognostication for body contouring surgery after bariatric surgery.

Objective: Body contouring surgery has become a steadily increasing part of weight loss treatment in the population of patients electing to undergo bariatric surgery. This study aims to elicit factors that can be used to prognosticate which bariatric surgery patients will choose to undergo body contouring procedures.

Methods: A database of 381 patients who underwent gastric bypass surgery between August 2002 and December 2005 was retrospectively reviewed.

An effective technique for salvage of cardiac-related devices.

Millions of patients require implantable cardiac devices for management of cardiac dysrhythmias. These devices are susceptible to erosion, exposure, or infection and plastic surgeons are consulted when salvage is required. As of yet, an anterior muscle-splitting approach to effectively and safely relocate the device into the subpectoral position has not been described in the plastic surgery literature.

Sternal reconstruction after cardiac transplantation: a case of an oversized donor heart.

Background: We present a unique case of a cardiac transplant recipient who received an oversized heart.

Methods: To allow the chest to accommodate the organ, extensive resection of the bony chest wall was performed. As both pectoralis major myocutaneous flaps and omental transposition were insufficient to cover the wound, a chest rotational flap was chosen.

Significant predictors of complications after sternal wound reconstruction: a 21-year experience.

Background: We sought to identify patient comorbidities that predict complications after tissue flap sternal reconstruction.

Methods: A retrospective study, December 1989 to December 2010, analyzed numerous comorbidities, including diabetes mellitus (DM), hypertension (HTN), coronary artery disease, congestive heart failure (CHF), and renal insufficiency, as independent risk factors for postoperative complications. Pearson χ2 test, Fisher exact test, 2-sample t test, and median-unbiased estimation were used for data analysis.

Bile salt supplementation acts via the farnesoid X receptor to alleviate lipopolysaccharide-induced intestinal injury.

Background: Intestinal barrier integrity may be disrupted in many conditions allowing for bacterial invasion and ensuing systemic illness. We investigated the efficacy and mechanism of bile salts in protecting the intestinal mucosa integrity after injury through stimulation of cell proliferation and an increased resistance to apoptosis.

Methods: Over 7 days, wild-type C57Bl/6J and Nr1h4(tm1Gonz)/J (farnesoid X receptor [FXR] knockout) male mice received either liquid rodent chow alone (for control animals) or with added 50 mg/kg per day of taurodeoxycholic acid (TDCA; for experimental animals).

Z-mammaplasty: a novel concept in mastopexy.

Background: The inverted-T technique is the most popular skin pattern used for mastopexy, but short scar variations have increased in popularity over recent years. With respect to nipple elevation, superior, superomedial, medial, inferior, lateral, and central pedicle designs have been described.

Objectives: We introduce a novel concept for mastopexy, the glandular Z-mammaplasty, and assess its anatomic and technical feasibility.

The sentinel fat pads: the relationship of the ROOF and SOOF to the temporal nerve in facial rejuvenation.

Background: A great number of studies have reported on the temporal branch anatomy and its relationship to the fascial layers and various fat pads of the temporal region, but no article has included information on the relationship of the temporal nerve to the retro-orbicularis oculi fat (ROOF) and/or the suborbicularis oculi fat (SOOF).

Objectives: The authors report the results of a series of human cadaver temporal nerve dissections, with particular attention paid to its relation to the ROOF and the SOOF. The results of a literature review and a subsequent open browlift are also reported to confirm the results of the cadaver study.
