A New Technique for Fascia Closure
Introduction: Because of the risk of herniation, all port sites are recommended to be closed after laparoscopic surgery. However, port-site closure is difficult especially in obese case. Full-thickness closure of trocar wound is a time-consuming and frustrating task. A lot of devices for this closure have been introduced. However, they are not cost-effective. We report… Continue Reading

A Pain in the Neck! the Relationship of Video Monitors to Surgeon’s Stress
Introduction: Surgeon-technology interfaces are a vital factor contributing to ergonomic risk. The display monitor is one such interface associated with physical eye and neck symptoms experienced by laparoscopic surgeons. The development of new technologies has permitted the traditional CRT display stationed on an instrument cart to be replaced by LCD system located on a boom.… Continue Reading

Attention Disruptions to the Operating Surgeon During Laparoscopic Cholecystectomy
Introduction: Disruptions to surgical workflow have been correlated with an increase in surgical errors and suboptimal outcomes in patient safety measures. Yet, our ability to quantify such threats to patient safety are woefully inadequate. Data is needed to gauge how the laparoscopic operating room (OR) work environment, where the visual and motor axes are no… Continue Reading
Bioluminescent Endoscopic Imaging: Technical Requirements of the Chemistry and Camera System
Objective: Bioluminescent chemistry can be infused as an angiography media and by developing endoscopic techniques for bioluminescent imaging (BLI) we have previously demonstrated sensitive visualization of anatomic structures, including the biliary tree and vascular beds. In nature bioluminescence is light produced by a chemical reaction within a living organism. In BLI applications, a luciferin (the… Continue Reading
Broad-view Camera System for Endoscopic Surgery
Introduction:The disadvantage of endoscopic surgery (laparoscopic surgery, NOTES, etc.) is the narrow operative field provided by a single endoscope. The broad-view camera system (BVCS) has been developed with the aim of providing a wide-ranging view by using miniature camera units located on the inside of the patient's body. The BVCS can automatically record not only… Continue Reading

Comparative Analysis of the Optical Characteristics of a Fixed-Angle, Flexible-tip, and Variable-view Laparoscope
Objective: Standard rigid laparoscopes have a fixed-angle of view and flexible-tip laparoscopes require external deflection of the tip to alter the viewing angle; therefore requiring additional room for maneuverability in restricted spaces. The purpose of this study is to compare the optical properties and characteristics of fixed-angled laparoscopes and an externally deflectable, flexible-tip laparoscope to… Continue Reading

Comparison of Two Different Energy-based Vascular Sealing Systems for the Hemostasis of Various Types of Arteries in a Porcine Model – Evaluation of Ligasure Forcetriad –
Background: Bipolar electrosurgical and ultrasonic devices are routinely used for hemostasis in open and advanced laparoscopic surgery. Currently available ultrasonic and bipolar electrosurgical instruments with tissue sensing technology can seal blood vessels with efficacy equal to that obtained with surgical clips or ligatures. Recently, a new generator (ForceTriadTM) has been developed . This new electrosurgical… Continue Reading

Effect of Laparoscopic Surgery on Surgeons’ Health
A lack of understanding the ergonomics of laparoscopic surgery has a potential to pose health problems for the surgeons. This study was planned to asses the prevalence of ergonomic problems associated with laparoscopy. Questionnaires designed to asses the frequency and degree of physical discomfort practicing surgeons during laparoscopy were evaluated in 210 cases.The average age… Continue Reading

Optimized Vessel Sealing Utilizing Temperature Control
Introduction: Temperature-controlled vessel sealers generate strong vessel welds and maintain a high safety profile. Combining focused bipolar RF energy, tissue compression, and time these devices forge collagen welds in 7 mm vessels with a burst strength averaging 800 mmHg. A novel technology enables precise temperature control at a molecular level, thus preventing overheating, char, and… Continue Reading

Quantified Surgeon Spared Mental Resource in a Laparoscopic Suturing Task
Introduction: A surgeon’s level of mental workload is elevated in suturing, particularly during the learning phase. Training decreases the workload of the surgeon as movements become automatic and require less mental resources. To objectively quantify mental workload during learning, we developed a simple bench-top measurement tool to assess the spared mental resources that are available… Continue Reading
Simple Technique of Less
Introduction : Laparoscopy is now established as a surgical treatment of choice for many abdominal problems. Laparo Endoscopic Single Site Surgery (LESS) has emerged as a novel laparoscopic surgical technique. Ports for LESS are under development. We have developed a simple technique of performing LESS.Methods and Procedures : A curvilinear sub-umbilical incision was made. An… Continue Reading

Single Port Cholecystectomy with the Transenterix System: Simple and Safe
Introduction: Single port or single incision cholecystectomy with current devices is limited by in-line visualization and instrumentation. A single port access system with articulating arms and strong instrumentation should minimize these issues. The TransEnterix system may facilitate safe and straightforward single port surgery. Methods: The TransEnterix single port surgery system was used to complete laparoscopic… Continue Reading
The Effect of Tissue Compression on Staple Line Failure
Introduction: Circular staplers are often used to form a gastrojejunostomy. However, leaks occur 0.1-3% of the time resulting in serious morbidity and mortality. The purpose of this study is to evaluate the effect of tissue compression on the acute strength of a stapled anastomosis. Methods: Twenty-seven freshly harvested porcine stomachs and segments of small intestine… Continue Reading

Usefulness of Co2 Gas Conditioner in Laparoscopic Surgery
Background:Cloudiness and dirt on a tip of endoscopy are one of the causes to stop an operation. An operator feels great stress from this trouble in order to perform a best operation. In this paper we present a new system to solve this problem. There are two kinds of problem on the tip of endoscope,… Continue Reading

Using Vibration to Provide Force Information in Surgery
USING VIBRATION TO PROVIDE FORCE INFORMATION DURING SURGERYBell, A., *Schwaitzberg, S.D., Cao, C.G.L., Tufts University, Cambridge Health Alliance Laparoscopic surgeons receive distorted force feedback during tissue manipulation. Research shows that sensory augmentation using vibrotactile stimulation with amplitude modulation enhances performance in tissue differentiation tasks. It was hypothesized that the capacity of information transmission through vibration… Continue Reading
