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
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

Evaluation of New Operation for Morbid Obesity
Abstract Background: Bariatric surgery in particular malabsorptive procedures with the rapid weight loss, and anatomical changes in the gastrointestinal tract of patients leads to sever nutritional and metabolic complications .This work is aiming to avoid the nutritional and trace elements deficiency post bariatric malabsorptive procedures.Aim of the work is to avoid vitamins and trace elements… Continue Reading
Experienced Laparoscopic Surgeons Gain Significant Advantages Using 3d Passive Polarising Displays
Objective 3D surgical imaging systems provide stereoscopic depth cues that are lost in conventional 2D display systems. Recent improvements in stereoscopic projection technology using passive polarising displays have significantly improved novice surgeon performance during the acquisition of minimally invasive surgical skills. This study aims identify if passive polarising 3D displays provide similar benefits for expert… Continue Reading
Feasibility of Endoscopic Transumbilical Thoracic Surgical Lung Biopsy and Pericardial Window Creation
BACKGROUND To date there are no practical platforms for performing natural orifice transluminal endoscopic surgery (NOTES) in the thoracic cavity. Using the canine model, this study evaluates the feasibility of single incision transumbilical endoscopic surgery for thoracic exploration, lung biopsy, and pericardial window creation.METHODS Eight dogs were used for this study. A homemade metallic tube… Continue Reading
Fluorescent Augmentation of Bile Ducts’ Visualization at Laparoscopic Cholecystectomy By Using Fluorescein and Ultraviolet Generating and Conducting Device
Objective and backgroundThe purpose of this new technique is to improve visualization of the extrahepatic bile ducts at laparoscopic cholecystectomy. The idea depends on the fact that intravenously-administered fluorescein is excreted by the liver and its concentration in bile reaches 500 times that of plasma. Ultraviolet A (UVA) excites fluorescein and causes it to emit… Continue Reading
Functional Results of Lower Esophageal Sphincter Mechanism Following Different Techniques Used for Cruroraphy for Laparoscopic Hiatal Hernia Repair ; Early Results of Randomized Controlled Trial
Aim:The prospective randomized trial was designed to evaluate the impact of different cruroraphy techniques used for laparoscopic repair of hiatal hernias. Material and Methods:Between January 2010-december 2011 , patients were randomly assigned for 3 groups having hiatal hernia> 2 cm. 24 h pH monitoring was performed using pHday2 Menfis,Italy and esophageal manometry was performed using… 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
Hepatic Inflow Restriction Device
During partial hepatectomy, most commonly performed for the treatment of liver tumors, blood loss is a significant patient risk, as the liver is a highly vascular organ with blood flow rates on the order of 1500 ml/min., which is approximately 25% of total cardiac output. Excessive liver bed bleeding can also obscure the operative field,… Continue Reading
Initial Experience With a Modified Mini Laparoscopic Technique for Cholecystectomy
Introduction: The use of smaller instruments in laparoscopic cholecystectomy has been well described in a number of trials, but the range of patients in which this minimalist technique can be used in is narrow. Here, we report on the use of a modified mini laparoscopic cholecystectomy in a range of patients with variable BMI’s. … Continue Reading
Laparoscopic Bile Duct Exploration Using Video-gastroscope
Background: Laparoscopic bile duct exploration (LBDE) is now a standard procedure in many centers for the management of ductal stones in calcular GB patients. The lowest incidence of retained CBD stone after duct exploration is achieved only with the use of operative choledochoscopy. Available choledochoscopes are so fragile, with fine channels and minimal control of… Continue Reading
Leveraging Mobile Health Technology in a Model for Home-based Primary Care: a Demonstration Project
House calls by physicians and physician extenders are time-consuming and have historically been poorly reimbursed. Nevertheless a number of factors are driving a resurgence in this form of patient-provider encounter. The burgeoning fields of mobile health technology, mobile communications and electronic medical records are converging to create new opportunities to leverage advances in a robust… 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
Measuring tissue oximetry as a method for evaluating acute tissue response to compression
INTRODUCTION Tissue percent oxygenation levels are affected by the amount of compression applied, the purpose of this study was to develop a method to evaluate the change in tissue oxygen saturation level during compression and uncompression. During surgery, tissue is compressed for various reasons, including grasping, manipulation and stapling. Excessive compression may irreparably damage tissue… Continue Reading
