The Cost of Achalasia: Quantifying the Effect of Symptomatic Disease on Patient Cost Burden, Treatment Time and Decreased Work Productivity
OBJECTIVES – Achalasia is an uncommon disease of esophageal motility, characterized physiologically by failure of the lower esophageal sphincter to relax upon swallowing, and the absence of effective peristalsis in the body of the esophagus. Although the incidence of achalasia is low, the burden of suffering is high because it is a chronic incurable disease… Continue Reading

The Development and Testing of a Tethered, Independent Camera for NOTES and Single-site Laparoscopic Procedures
Background:“Tunnel vision” associated with flexible endoscopes used in NOTES and rigid laparoscopes used in Single Site Laparoscopic (SSL) procedures can present the surgeon with a disorienting view of familiar surroundings. Because the working tools are in-line with the view in these approaches, it is also difficult to achieve adequate instrument triangulation, a critical component of… Continue Reading

The Development and Testing of New Rigid and Flexible Fixation Staplers for NOTES Applications
Background:Many of the devices used in early human NOTES procedures were originally designed for intralumenal work and are therefore limited in functionality due to constraints imposed by current flexible endoscopes. The invention of large diameter flexible trocars, however, has opened the door for delivery of true surgical capabilities such as stapling. Additionally, the transvaginal approach… Continue Reading

The Diagnostic Efficacy of Natural Orifice Translumenal Endoscopic Surgery (notes): Is There a Role in the Intensive Care Unit?
Background: Evaluation of a potential source of abdominal sepsis in a critically ill patient can be challenging. With flexible endoscopy being readily available in this setting, we sought to evaluate the diagnostic efficacy of a trans-gastric NOTES peritoneoscopy vs. laparoscopic exploration in the identification of common intra-abdominal pathology in a porcine model.Methods: In this acute… Continue Reading

The Effect of Colectomy on Pancreatic Infections in a Model of Experimentally Induced Acute Pancreatitis.
Introduction; Prevention and treatment of secondary pancreatic infection is currently the main goal of treatment for acute necrotizing pancreatitis. The colon has been considered a major source of bacteria causing infection of pancreatic necrosis in acute pancreatitis. Our aim is to study the role of near total colectomy in reducing bacterial translocation and infection of… Continue Reading
The Effect of Inhaled Lps on the Development of Bronchiolitis Obliterans.
Introduction: Gastroesophageal reflux-associated chronic aspiration contributes to the development of various lung disease processes including chronic pulmonary allograft dysfunction, as manifested by the histologic finding of bronchiolitis obliterans (BO). The TLR-4 innate immune pathway is thought to play a role in these processes and may be activated by bacteria within the gastric contents. Here we… 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

The effect of videogame “warm-up” on performance of LS surgery tasks
Introduction: “Warming up” before performing a skill can lead to early and sustained excellence. Performing procedures in the laparoscopic arena requires special training to perform at a superior level. Our previous studies suggest that videogame play is associated with superior laparoscopic performance (1), so we investigated whether surgeons benefited from practicing video games immediately before… Continue Reading

The Effectiveness of Gastric Band: A Retrospective Seven-year U.s. Follow-up Study
Objectives: To assess the efficacy of gastric band during 7 years of follow-up. Methods: A retrospective database analysis was conducted using longitudinal data from gastric band patients between Jan 1, 2000 and Feb 29, 2008. Patients were included for the efficacy analysis if they were at least 18 years of age at surgery date and… Continue Reading

The Healthy Culture of Competition
In August 2008 the American Board of Surgeons announced new requirements for general surgery residents seeking board certification that will be implemented beginning July 2009. All residents in the class of 2009-10 and later will have to complete the Fundamentals of Laparoscopic Surgery (FLS) certification in addition to the current necessary certifications in ACLS and… Continue Reading

The Huge Hiatal Hernias. Can the Robot Help?
Introduction: Over the past decade, laparoscopic surgery became the standard approach for the repair of hiatal hernias. Large hiatal hernias remain challenging to the laparoscopic surgeon. The difficulties originate from the depth of the hernia in the mediastinum as well as the narrow orifice (hiatus) to dissect beyond.We present a novell study for the robotic… Continue Reading
The Immediate Re- Resection of T1b Incidental Gallbladder Carcinoma- Indication or Overtreatment
Introduction: The indication for an immediate re-resection (IRR) in T1b incidental gallbladder carcinoma (IGBC) is debated in the literature, and different recommendations are often drawn based on data collected from only small groups. But the management of IGBC is difficult, because there are no established guidelines.A IRR is recommended in cases of T2 tumours and… Continue Reading

The Impact of Body Mass Index (bmi) and Intraperitoneal Fat Tissue on Laparoscopy Assisted Gastrectomy for Gastric Cancer
Introduction) After adopting preoperative assessment of the perigastric vessels using 3D-CT and standardization of the procedures, obesity still influences smooth laparoscopy assisted gastrectomy (LAG). We evaluated the impact of body mass index (BMI) and area of intraperitoneal fat tissue on the risks of LAG.Patients and methods) The 51 patients who performed LAG for gastric cancer… Continue Reading

The Impact of Co2-pneumoperitoneum on Liver Regeneration After Liver Resection in a Rat Model.
IntroductionDuring the past years, laparoscopic hepatic resection is beeing performed by an increasing number of surgeons. Despite many advantages of the laparoscopic procedure, it is unclear if the pneumoperitoneum affects the postoperative liver regeneration after liver resection. The aim of the present study was to investigate the influence of a CO2-pneumoperitoneum (PP) on liver regeneration… Continue Reading

The Impact of Different Commercially Available Antiadhesive Barriers in Experimental Ipom Hernia Repair Using a Polypropylene Mesh
Background:Intraperitoneal onlay mesh plastic technique (IPOM) is a common technique for ventral hernia repair. Adhesion formation, seroma formation, impared functionality of the abdominal wall, and chronic pain are frequently observed complications. Adhesions are probably the most important side effect and can be evoked by meshes as well as fixation devices. Different mesh concepts for adhesion… Continue Reading
