3d NOTES Navigation System By Magnetic Scope Detection and Osirix Virtual Laparoscopy
Purpose：In NOTES (Natural orifice translumenal endoscopic surgery), the first barrier of the operation in the abdominal cavity is scope orientation. Particularly transgastric NOTES is regarded as a challenging endoscopic procedure because of the unpredictable nature of scope formation and location in the abdominal cavity. These forced situations may result in an incomplete or lengthy procedure… Continue Reading

A Comparison of the Clinical and Economic Outcomes for Open Versus Minimally Invasive Appendectomy and Colectomy: Evidence From a Large Commercial Payer Database
INTRODUCTION: Appendectomy and colectomy are commonly performed surgical procedures. Despite evidence demonstrating advantages to the minimally invasive surgical (MIS) approach, the prevalence of open procedures is higher. It remains controversial whether the MIS approach is safer or more cost effective. METHODS: A retrospective analysis was performed using a large commercial payer database. The data included… Continue Reading

A Metastatic Colon Cancer Model Using Non-operative Trans-Anal Rectal Injection
(^) denotes superscript Background: This study was conducted to develop a non-invasive orthotopic model for metastasis of colon and rectal cancer using a trans-anal approach that is non-operative, reproducible, and easy to perform. Currently, the most accurate orthotopic representation of metastatic human colon cancer is a cecal injection. The trans-anal model allows for further examination… Continue Reading

A Multitasking Platform for NOTES; A Bench Top Comparison of a New Device for Flexible Endoscopic Surgery and Standard Dual Channel Endoscope * *supported By a Noscar Grant (2006)
Background: Complex surgery requires precise, independent coordination of two instruments that can perform multiple tasks such as traction and counter traction, precise dissection, and tissue approximation. All of these are difficult to achieve with standard dual channel scopes, which have been used for most of the human NOTES cases today. The development of a multitasking… Continue Reading

A NOTES Survival Study of a Novel Gastric Closure Device: Loop-Anchor Purse-string
INTRODUCTION: Gastric closure is a key consideration in NOTES. Numerous closure methods have been reported, but none stands out as superior. Whatever the method, it should be effective, durable, tight, and easy to perform. We report our results with a new enteric closure device: Loop-Anchor Purse-String (LAPS). METHODS: Our method was previously described on explanted… Continue Reading

A Population-based Analysis of Emergent Vs. Elective Hospital Admissions for an Intrathoracic Stomach
Introduction: Large scale population based analyses of the demographics and management and healthcare resource use in patients with an intrathoracic stomach are largely unknown. This issue has become even more important with the aging of the population. Our objective was to estimate the magnitude of the problem and to assess the use of hospital resources… Continue Reading

A Prospective, Randomized, Double-blind, Placebo Controlled Trial of Dexamethasone in Preventing Postoperative Nausea in the Laparoscopic Gastric Bypass Patient.
Postoperative nausea in patients undergoing laparoscopic gastric bypass remains a common source of patient discomfort and can lengthen hospital stay. The reported incidence of nausea ranges from twenty to thirty percent. A single dose of dexamethasone has been shown to prevent postoperative nausea and vomiting in patients undergoing strabismus surgery and laparoscopic cholecystectomy. Dexamethasone has… Continue Reading

A Prospective Study Comparing the Surgical Outcomes Between Laparoscopic Surgery for Transverse and Descending Colon Cancer and Laparoscopic Surgery for Other Colon Cancers.
Introduction: Several prospective randomized trials have demonstrated the long-term oncological safety of laparoscopic surgery for colon cancer. However, transverse/descending colon cancers were excluded from prior randomized controlled trials, mainly because of technical difficulties. This study was designed to compare surgical outcomes between laparoscopic surgery for transverse/descending colon cancers and that for other colon cancers, in… Continue Reading

A Randomized Clinical Trial Comparing Cost and Effectiveness of Bipolar Vessel Sealers to Clips and Vascular Staplers in Straight Laparoscopic Colectomy
Introduction: This study compares the costs and effectiveness of two standard techniques for vascular control in straight laparoscopic colectomy.Methods: Patients scheduled for laparoscopic colectomy were randomized to bipolar vessel sealer (BVS; Ligasure Atlas, Covidien) or laparoscopic clips and vascular staplers (LCS). Time and ability to control the main vascular pedicles were recorded. Costs of disposable… Continue Reading

A Simplified Technique for Intrathoracic Stomach Repair: Laparoscopic Fundoplication with Vicryl Mesh and Bioglue Crural Reinforcement
Background: The laparoscopic repair of an intrathoracic stomach has been associated with a high recurrence rate of up to 50%. Studies describing the use of biological and non-absorbable mesh report a more durable repair. The aim of our study was to assess a simplified technique for intrathoracic stomach repair using absorbable vicryl mesh and bioglue… Continue Reading

Advanced Laparoscopic Techniques Significantly Improve Function of Peritoneal Dialysis Catheters
Background: Continuous Ambulatory Peritoneal Dialysis (CAPD) catheters provide an alternative to hemodialysis in an increasing population of patients with chronic kidney disease. However, CAPD catheters have traditionally been associated with high rates of non-function using both the open and laparoscopic approaches. New advanced laparoscopic techniques utilizing rectus sheath tunneling and selective omentopexy have been reported… 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
Auditory Stress Versus Mental Loading: The Effects on Laparoscopic Motor Skill Performance

Augmented Reality for Laparoscopic Surgery Using a Novel Imaging Method- Initial Results From a Porcine Model
Background: Intraoperative appreciation of visible anatomy along with awareness of underlying structures and vasculature is invaluable to the operating surgeon. The advent of minimally invasive techniques, with reduced tactile feedback and limited visual displays has only heightened the need for improved visualization of target anatomy and adjacent but visually imperceptible structures. Current laparoscopic images are… Continue Reading
