Notes Transanal Endoscopic Rectosigmoid and Left Colon Resection Using an Innovative Sterile Sigmoid Access Platform With Integrated Endoscopic Overtube
Introduction: NOTES transanal endoscopic rectosigmoid resection was previously demonstrated using the TEM platform (Transanal Endoscopic Microsurgery). However, the length of left colonic mobilization has been limited due to difficulties with instrument reach and tissue manipulation using standard TEM and endoscopic instrumentation. Recently, a novel innovative sterile sigmoid access platform (ISSA, Storz, Tuttlingen, Germany) was developed… 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
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
Novel Method for Comprehensively Assessing the Biomechanical Risks Associated With the Use of Minimally-invasive Surgical Instruments
OBJECTIVE OF THE TECHNOLOGYAs the incidence of neuromuscular disorders among laparoscopic surgeons increases, research to understand the biomechanical risks associated with the use of minimally-invasive surgical instruments has been underdeveloped. A method using detailed simultaneous biomechanical measurements was developed in order to analyze the quantities that are closely related to potential risks and to yield… Continue Reading
Port-less Laparoscopic Distal Gastrectomy.
Introduction: The single port laparoscopic surgery has becoming attractive technique prior to NOTES from points of view such as cosmetic figure and reduction of wound pain. In Japan this technique has been increasing recently. Aim and Methods: The aim of this paper was to assess the feasibility of single port laparoscopic distal gastrectomy. The indication… Continue Reading
PVDF to Detect and Autonomously Prevent Slip During Retraction in Laparoscopic Surgery
Objective During laparoscopic surgery tissue retraction is necessary for exposure of the operating field. Currently this is performed manually by grasping the tissue in laparoscopic forceps but could be performed automatically with an appropriate device. This would need to automatically detect when tissue is slipping from its grasp and react appropriately. Method Polyvinylidene fluoride (PVDF), a piezoelectric… Continue Reading
Real-time 2d-3d Image Converting Software With a Monocular Small Camera Toward the Lesser Invasive Laparoscopic Surgery
<Introduction and Objectives> 3D images for laparoscopic surgery had been rapidly accepted as useful tool especially in suturing maneuvering. Since recent trials such as single port surgery or NOTES require smaller devices, thinner camera will be effective to retain space inside the port. To provide depth cue using smaller endoscope, combination of small monocular endoscope… Continue Reading
Role of Ksarasutra Management in High Anal Fistula With a Histo-pathological Study
Introduction:High anal fistula, an ano rectal disorder usually results to a sequel to some variety of ano rectal abscesses. This problem is challenging task to surgeons and available surgical procedures like fistulotomy and fistulectomy not only results with incontinence and even recurrences (26.5%) are established. The surgical procedures not only makes the patients to undergo… 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. This study looks into the safety of clip-less hook diathermy division of cystic artery against the standard cystic artery division between clips. Objective: To study the outcome and safety of the clip-less hook diathermy… Continue Reading
Sleeve Tube: Novel Tool to Standardize Laparoscopic Sleeve Gastrectomy (lsg)
Objective: Laparoscopic sleeve gastrectomy [LSG] has been increasingly accepted as a definitive weight loss surgery. LSG is less complex than Roux En Y Gastric bypass with lesser complication profile but comparable outcome. Complications arising out of LSG are results of technical failures: misidentification of vital surgical landmarks, use of improper staple heights, inadvertent traction, unguided… Continue Reading
Sumotm System Facilitates Mucosotomy and Submucosal Tunnel Creation for Per-oral Esophageal Myotomy (POEM)
Objective:The POEM procedure for achalasia is a complex therapeutic flexible endoscopic technique, requiring extensive practice to learn. Initial experience with the POEM demonstrates that it has the potential to become the therapeutic procedure of choice in the future. However, in order for this to be achieved, the procedure needs to be simple, safe and easily… Continue Reading
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
