The Development of a Virtual Reality Colonoscopy Training Curriculum
The success of colonoscopy in colorectal cancer (CRC) prevention is dependent on operator competence in the detection and removal of adenomatous polyps. However, studies have shown substantial variability in polyp detection rates. Changes in clinical practice have led to a reduction in training opportunities; thus alternative methods of teaching have been developed. The advert of… Continue Reading
Gastrectomy and Hepatectomy By Multi Piercing Surgery Using 3-mm Diameter Electronic Control Forceps
INTRODUCTION: It is described in medical documents that Needlescopic Surgery by use of 3-mm diameter forceps is a minimally invasive surgery method which does not damage somatic pain nerves on the body surface. However, when we deal with bigger organs to be operated such as in gastrectomy or hepatectomy, we are faced with the problem… Continue Reading
Electrical Stimulation Therapy (est) of the Lower Esophageal Sphincter (LES) – Emerging Treatment for Preventing GERD in Achalasia Patients Treated With Les Mytomy
Objective of the technology or device – EST of LES is an effective treatment for GERD (Am J Gastro 2011; 106: S6). Chronic LES-EST improves LES pressure, reduces esophageal acid exposure and improves symptoms in GERD patients. Our objective was to see if LES-EST can control GERD in a patient treated with Heller myotomy who… Continue Reading
Novel Cmos Image Sensor Technology Improves Diagnostic Accuracy and Enables Economic Viability of Disposable Medical Imaging Devices
Objective/Background Image senor technologies such as charge-coupled devices (CCDs) image sensors have played a major role in digital medical imaging during past twenty years. With technological advancements such as backside illumination (BSI), CMOS image sensors began to take off in medical imaging applications. Novel CMOS-based image sensors offer enhanced image quality, low power consumption, improved… Continue Reading
The Subxiphoid Approach to Thyroidectomy Using the Ddes, a Flexible, Articulating, Single-incision Platform
OBJECTIVEThe cultural desire to avoid cervical incisions has motivated surgeons to develop alternative approaches to thyroid surgery. The most common technique employs an axillary incision and subcutaneous tunneling for resection of the thyroid. This access is more challenging in the obese patient, limiting the patients who are candidates for minimally invasive thyroid surgery. Further, traditional… Continue Reading
Verrotouch: Detection of Instrument Vibrations for Haptic Feedback and Skill Assessment in Robotic Surgery
Objective: Surgeons currently rely on visual cues to compensate for the lack of haptic information during robotic minimally invasive surgery (RMIS). We have developed VerroTouch, an RMIS accessory that provides surgeons with realistic audio and haptic feedback of instrument vibrations. This system has been implemented in both a box-trainer and a live porcine model. The… Continue Reading
New Area in Laparoscopic Hernia Repair: Devices for Mesh Introducing, Placing and Deploying
Background: The modern Meshes for intraperitoneal Ventral hernia repair create a barrier for bowel adhesion beside of capability of incorporation into the abdominal wall. Groin meshes become less irritating by reducing mesh weight and having bigger porosity. In spite of meshes progression and guidelines for the recommended surgical techniques the adaptation of Lap Hernias repair… Continue Reading
Early Experience With Peroral Endoscopic Myotomy (POEM)
OBJECTIVE: Peroral Endoscopic Myotomy (POEM) is an emerging new technique for treatment of achalasia. Here we describe the results of our early clinical experience with POEM. DESCRIPTION: Five patients (3 female, 2 male; age 30-73, mean 53) with manometry proven achalasia were enrolled in our IRB approved study and underwent POEM between June and October… Continue Reading
Wearable Technology Enables High Definition Wireless Audio-video (av) Communication to the Operating Room
Background: This group has previously reported work on a cart-based AV system for communication to the OR using the internet. This technology has been transformed into wearable technology to enable a less restrictive interface between the operating surgeon and mentor.Objective: To develop a mobile system using wearable technology that enables a mentor surgeon to communicate… Continue Reading
A Virtual Electrosurgery Simulator for Teaching and Training in Safe Usage of Energy
ObjectiveTo develop a virtual Reality (VR) simulator to teach the various mechanisms through which injury can occur when using electrosurgery during minimally invasive surgery. Description and MethodsInadvertent thermal injuries do occasionally occur when using electrosurgical devices. The 3 main mechanisms responsible are insulation failure, direct coupling and capacitive coupling. A force feedback enabled VR simulator… Continue Reading
Limited Incision Ileorectal Anastomosis and Cholecystectomy: A Case Report
Introduction: The trend towards minimally invasive procedures has progressed rapidly over the past several decades. Novel techniques and new technologies are constantly being introduced to perform increasingly complex procedures through very limited incisions. Utilization of an ostomy site for laparoscopic colorectal surgery has been described. We performed a cholecystectomy and ileorectal anastamosis (IRA) through an… Continue Reading
Novel Mesh Deployment Device Improves Efficiency of Laparoscopic Ventral Hernia Repair
Device Objective:Laparoscopic ventral hernia repair (VHR) is a well-accepted method for addressing abdominal wall hernia. The BARD ECHO mesh positioning system is a newly marketed device used to facilitate mesh placement and improve the efficiency of laparoscopic VHR. Description:The BARD ECHO device consists of a pre-attached inflatable balloon packaged with Ventralight ST polypropylene mesh and… Continue Reading
The Sealed Incision Multiport (simport) for Laparoendoscopic Surgery
Objective As minimal access surgery continues to evolve for greater patient benefit, there is a need for enabling technology that performs simply, reliably and efficiently in response to surgeons' real-world requirements. Furthermore, novel devices need to function intuitively and seem immediately familiar and so need be compatible with existing instrumentation and accommodate variety of use in… Continue Reading
Safety of Clip-less Hook Diathermy Division Against Standard Clipped Division of Cystic Artery in Laparoscopic Cholecystectomy
Back ground: Laparoscopic Cholecystectomy is one of the most commonly performed surgery. Various methods of Cystic artery division are in practice.

Back to the Future: Open Cholecystectomy ‘hybrid’ Model Developed Through Historical Re-enactment.
Objective: Cholecystectomy is the most frequently performed general surgical procedure. Prior to Mouret (1987), surgical trainees were routinely exposed to the open procedure which was the gold standard treatment of the time. The aims of reducing postoperative morbidity and length of hospital stay have historically driven the change in surgical approach; from open to laparoscopic,… Continue Reading
