Novel hands-free pointer improves instruction efficiency in laparoscopic surgery.
OBJECTIVE: To determine if a novel, hands-free, multi monitor, pointer improves instruction efficiency in a simulated laparoscopy environment.METHODS: Twenty arbitrary instruction points were selected on a picture of a partially dissected cholecystectomy within a laparoscopic trainer box. A single instructor guided twenty trainees to locate points with a laparoscopic instrument. Points were visible to the… Continue Reading

Optical Chest Tube Placement: A Feasability Study
Traditionally, chest tube placement has occurred as a blind technique, as such having inherent possibility for error. Given the advancement of optics and the evolution of trocar technologies we have developed a novel method for optically guided chest tube insertion. Using a standard 12mm dilating optical trocar and 0 degree 10mm lens we place chest… Continue Reading

A Comparison of Permanent and Nonpermanent Staple Line Buttressing Materials for Linear Staple Lines During Laparoscopic Roux-en-Y Gastric Bypass (lgbp)
Objective: This study analyzed our experience with 3 different buttressing materials for creating the gastric division during LGBP.Methods: From June 2001 to October 2006, 1451 consecutive patients undergoing LGBP had buttressing material used for the staple creation of the gastric pouch. Permanent bovine pericardial strips, Peristrips Dry® (PSD) was used in 926 cases, Seamguards® (SG),… Continue Reading
The Patient as Instrument Stand – A Time-Motion Study of Sub-optimal Instrument Placement
Background: When not in use, instruments are sometimes placed on top of the patient’s body during laparoscopic procedures. Such instrument “hoarding” has been previously mentioned as a non-optimal practice. Ergonomic design of surgical workplaces may improve efficiency while maintaining safety. However, no studies have been carried out to describe where instruments are placed during surgery.… Continue Reading

Deconstructing Operative Flow – a Focus on Anticipatory Movements
Introduction: Efficient instrument movement is a vital part of a well-coordinated operating environment, and is a reflection of optimized ergonomic and human factor issues. In order to make assessments of these movements, objective, reproducible metrics are needed. In this study, instrument flow analysis is utilized to characterize anticipatory movements of the operative team.Methods: Five laparoscopic… Continue Reading
Eliminating Paradoxical Imaging During Laparoscopic Surgery in the Age of Head-Mounted Display
BACKGROUND: Complex laparoscopic tasks are nearly impossible to complete when the telescope is pointed toward the operator (paradoxical image). Attempts at image manipulation have been reported, but altered monitor displays may introduce even more confusion. The availability of high-quality, lightweight head-mounted displays (HMD) now allows individualization of the laparoscopic image. We sought to demonstrate that… Continue Reading

Minimal Thermal Effects of a Continuous Power Delivery System with Bipolar Sealing Capability As Measured By High Definition Thermography
Objective of the study: Evaluate the real time thermal footprint of a continuous power delivery technique with bipolar sealing technology as measured by high-definition thermography. Description of the methods: Thermography is the use of an infrared imaging camera to record the radiating heat in real time, as thermal energy is emitted from an object. In… Continue Reading

Better Performance of Laparoscopic Simulator Tasks with High Definition Camera Technology: A Pilot Study
Background: The availability of a High Definition (HD) laparoscopic camera improves image quality, however whether this translates into improved performance compared to a standard camera (SD) is not known. We investigated whether performance in a laparoscopic simulator would be affected by the use of a HD camera.Methods: 5 subjects (2 surgical residents and 3 laparoscopic… Continue Reading

Laparoscopic Adjustable Gastric Banding in patients older than 65 years is safe and effective
There are few publications in the literature reporting the outcome of laparoscopic adjustable gastric banding (LAGB) in the elderly population. From November 2001 to March 2007, 708 LAGB procedures were performed by two surgeons at Loyola University Medical Center. Twenty-one of the 708 patients were age 65 or older at the time of operation (65… Continue Reading

The Trans-Gastric Endoscopic Rendez-vous Technique (TGER) for Removal of Eroded Non-Adjustable Gastric Bands
Introduction:The application of the nonadjustable gastric band for the treatment of morbid obesity was common in the 1980s. Unfortunately, it was associated with an unacceptable re-operative rate with numerous post-operative complications such as gastric erosion. Removing an eroded gastric band is fraught with difficulty secondary to the extensive inflammatory response around the proximal stomach and… Continue Reading

VATS Vagotomy for the treatment of Chronic Marginal Ulcer
Background:Gastric Bypass is an increasingly common procedure. Associated rare complications have a related increased occurrence. Marginal ulceration at the gastrojejunal anastomosis has a reported incidence of 5 to 12%. In most instances these ulcers can be managed conservatively using acid suppression with proton pump inhibitors and sucralfate. There is a troublesome subset of this population,… Continue Reading

Comparative Weight Loss Analysis of Laparoscopic Gastric Bypass and Adjustable Gastric Band
Introduction: Comparative weight loss analysis between the gastric bypass (GB) and the adjustable gastric bypass (AGB) is difficult due to the need for long-term follow-up the need to control for potential confounders (i.e. initial BMI).Methods: Longitudinal mixed-effects models were used to analyze weight loss after either the GB or AGB. The multivariable analysis included controls… Continue Reading

Low Complication Rates Following Laparoscopic Gastric Bypass. a Report from the Bariatric Surgery Center of Excellence.
Introduction: Bariatric surgery remains the only modality to provide morbidly obese patients with a significant and sustained weight loss. Laparoscopic Roux-en-Y Gastric Bypass (LRGB) has become the gold standard of bariatric procedures. However significant but variable complication rates following laparoscopic gastric bypass were reported. Materials and Methods: We present our experience with 434 consecutive patients… Continue Reading

Laparoscopic Gastric Bypass Does Not Necessarily Increase the Propensity to Develop Internal Hernias
Background: Although laparoscopic Roux en Y gastric bypass (LGB) has been proven to have numerous advantages over the open technique, internal hernia formation has been cited as a common and life-threatening complication associated more frequently with the laparoscopic technique.Methods: A review of all patients who underwent a LGB between 2003 and 2007 by a single… Continue Reading
