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
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

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
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

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

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
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
Intussusception Complicating Post Gastric Bypass Pregnancy
OBJECTIVE: Only 10 cases of intussusception after Roux-en-Y gastric bypass (RYGB) surgery and 11 cases of intussusception complicating pregnancy have been reported in the literature with one previous case common to both groups. We present an unusual case of intussusception complicating pregnancy following open RYGB. METHODS: 34-year-old female had a normal vaginal delivery at full… Continue Reading

Reversal Rather Than Revision of Failed Bariatric Operation
Reversal Rather Than Revision of Failed Bariatric OperationsOperative revision and reversal represent treatment alternatives for patients who fail primary bariatric operations. This review focuses on a small group of patients who had reversal rather than revision of their primary operation.METHODS: This study reviews 2532 primary and 238 revisional operations that were performed by one surgeon… Continue Reading

Splenic Upper Pole Ischemia Following Sleeve Gastrectomy: First Case Report
Introduction: Laparoscopic Sleeve gastrectomy is relatively new surgical therapy for morbid obesity. The spleen receives it blood supply from the splenic artery and the short gastric vessels. We are reporting a first case of splenic upper pole ischemia following resection of the short gastric arteries in laparoscopic sleeve gastrectomy. Material and method: Gastrectomy and related… Continue Reading

Anastomotic Leak After Gastric Bypass for Morbid Obesity: Laparoscopic Management.
INTRODUCTION – Postoperative anastomotic leak after bariatric surgery is of low incidence but it has significant morbidity and mortality. This complication is often treated by open surgical means. We present our experience with laparoscopic management of anastomotic leak after laparoscopic Roux-en-Y gastric bypass (LGB).METHODS AND PROCEDURES –We retrospectively reviewed all anastomotic leak cases after LGB… Continue Reading

Does Visceral Fat Resection Give an Additional Benefit to Gastric Banding
Background Although the function of visceral fat has gradually become clear, the effect of visceral fat resection is still unknown. The aim of this study is to clarify the additional effect of visceral fat resection in an obese rat model of gastric banding. Methods Fourty male Zucker fatty rats were followed for 8 weeks after… Continue Reading

Laparoscopic Sleeve Gastrectomy: Early Outcomes At a Military Training Center
Background: Laparoscopic sleeve gastrectomy (LSG) has recently gained support as a single-staged and stand-alone bariatric procedure. Reports of excess weight loss of 51-83%, reduction in patient co-morbidities, and decreased operative morbidity compared to laparoscopic gastric bypass have garnered support for LSG. This study represents an initial outcome analysis of LSG performed solely at a military… Continue Reading

A Comparison Study of 100 Consecutive Laparoscopic Roux-en-Y Gastric Bypasses and 100 Lap-bands During the Learning Curve
The learning curve for laparoscopic gastric bypass has been estimated at 100 cases. We compared data from the first 100 consecutive laparoscopic roux-en-y gastric bypasses (LRYGB) with the first 100 consecutive laparoscopic adjustable gastric bands (LAGB) in a minimally invasive fellowship-trained surgeon's experience upon joining an established bariatric practice. Results: Patients undergoing LRYGB were slightly… Continue Reading
