Flexible Endoscopic Scissors: A Comparative Study
INTRODUCTION: The long length and small diameter of endoscopic working channels present significant design obstacles for instruments such as endoscopic scissors that require reliable function and strong closing force. This study compares the function of four endoscopic shears.METHODS: Endoscopic scissors from four companies were trialed - the Olympus FS-3L-1 (Olympus, Tokyo, Japan), EES Prototype Device… Continue Reading

Flexible Endoscopic Sub-rectal Sheath Tunneling Allowing Intraperitoneal Visualization During Single Incision Ventral Hernia Mesh Repair
Objective: Dual-layer mesh products are optimal for a subset of ventral hernia repair. While small umbilical defects are easily accessed through a single incision, intraperitoneal visualization is limited and only possible prior to mesh placement. The purpose of our study was to evaluate the feasibility of a single-incision flexible endoscopic sub-rectal sheath tunneling technique to… Continue Reading

Fluorescent Cholangiography During Laparoscopic Cholecystectomy By Intravenous Injection of Indocyanine Green
Objective of the technique: To delineate bile duct anatomy during laparoscopic cholecystectomy (LC) using fluorescent cholangiography with preoperative intravenous injection of indocyanine green (ICG).Methods: Our fluorescent cholangiography technique is based on the principle that ICG is excreted into bile and that protein-bound ICG emits light with a peak wavelength of around 830 nm when illuminated… Continue Reading
Follow-up and Distance From Centre Are Important Determinants in Weight Loss Post Laparoscopic Adjustable Gastric Banding.
IntroductionIn this study, we examine the importance of regular post-operative follow-up and the effect of geographical distance from the centre of follow-up on long term weight loss post laparoscopic adjustable gastric banding (LAGB). MethodOver 11 years (1997- 2008), 140 patients underwent LAGB. Post-operatively patients were invited to attend a monthly nurse-led follow-up clinic, to assess… Continue Reading

From Start to Finish: 117 Consecutive Laparoscopic Adrenalectomies
Introduction: Laparoscopic adrenalectomy has quickly replaced open adrenalectomy as the procedure of choice. The purpose of this study is to describe a single institution experience with laparoscopic adrenalectomy over a 12 year period.Methods: Retrospective chart review was done for all patients who underwent laparoscopic adrenalectomy between 1996 and 2008. Patient preoperative, intraoperative and postoperative data… Continue Reading

Functional and Comparative Evaluation of Flexible Monopolar Endoscopic Scissors.
1. Objective of the study: The success of natural orifice translumenal endoscopic procedures requires reliable, accurate tissue dissection and suture cutting comparable to current laparoscopic tools. A prototype flexible endoscopic scissor for tissue biopsy, dissection, enterotomy creation and suture cutting was evaluated.2. Description of the methods: Acute study in 2 domestic pigs. Laparoscopic access provided… Continue Reading

Fundamental Surgical Skills Were Retained Three Months After Completion of Our Robotic Surgery Training Program
Introduction: Evaluation of the learning curve of robotic surgery has shown reduced errors and decreased task completion and training times, as compared with regular laparoscopic surgery. However, most training evaluations of robotic surgery have only addressed retention in less than a month after completion of training. Aim: Our goal was to investigate the amount of… Continue Reading
Gages: A Valid Measurment Tool for Technical Skills in Flexible Endoscopy
Introduction: GAGES (Global Assessment of Gastrointestinal Endoscopic Skills) was created to provide an objective measure of endoscopic skills to better assess training curricula. Pilot data have shown GAGES to meet high standards of reliability and validity. The aim of this multicenter study was to demonstrate the practicality and external validity of this instrument, while providing… Continue Reading

Gastric Band Manometry: Are Pressure Measurements and the Band Pressure Ratio Useful?
Introduction: Successful band adjustment requires a method to measure adequate restriction without over-inflation. There is no standardized optimal volume of saline used during band filling. We investigated what the relationship was between subjective optimal band filling and band pressure measurements.Methods: Band pressure measurements were recorded at the first and second band adjustments in patients who… Continue Reading

Gastric Bypass Improves Musclo-skeletal Quality of Life
IntroductionMorbid Obesity is the leading public health epidemic of the industrialized world with bariatric surgery as the only effective and enduring treatment for this disease. Gastric Bypass is known to be very effective for weight loss and can also improve obesity related comorbidities like joint disease. Joint disease may be difficult to assess without radiographs.… Continue Reading

Gastric Bypass Pouch Revision and Stoma Plication: A Novel Technique Using a New Endoluminal Suturing Device
Weight regain following gastric bypass has been associated with enlargement of the gastric pouch and with dilation of the gastro-jejunal anastomotic stoma. We developed a new technique for revision of the pouch and stoma using a novel endolumenal suturing device in an ex vivo model porcine stomach model. The novel prototype device is a flexible… Continue Reading

Gastro-colonic Fistula After Roux-en-Y Gastric Bypass for Morbid Obesity
IntroductionThe incidence of morbid obesity in the United States is increasing. Roux-en-Y Gastric Bypass is a surgical treatment for morbid obesity resulting in weight loss and control or resolution of obesity-related co-morbidities, however, is not without complications. More common post-surgical complications include anastamotic leaks or strictures, bowel obstruction or vitamin/mineral deficiency. While relatively rare, marginal… Continue Reading

Gastrointestinal Bacterial Clearance Levelizer for NOTES Using a Cleaning Unit and a Digital Image Analyzer with a Confocal Laser Microscope
In NOTES, it is mandatory to maintain a high bacterial clearance level in the gastrointestinal tract, the route of access to intraperitoneal cavity. In NOTES that is conducted through the lower gastrointestinal tract that is convenient among routes of access to intraperitoneal cavity, it is very difficult to obtain a bacterial clearance level at which… Continue Reading
