Colonic Sterilization for NOTES Procedures – a Comparison of Two Decontamination Protocols
Introduction:In the 2005 White Paper, prevention of infection was named as one of the ten potential barriers to performing NOTES surgery. The aim of this study was to evaluate the effect of two different sterilization protocols on the bacterial counts in the swine colon while preparing for NOTES surgery.Methods:After placing a proximal colon balloon, 16… Continue Reading

Combined Prone Thoracoscopy and Supine Laparoscopy for treatment of an Epiphrenic Diverticulum
The laparoscopic treatment of epiphrenic diverticula via a totally abdominal approach has been well described. One of the challenges of the laparoscopic approach to the treatment of large epiphrenic diverticula has been safe and adequate proximal dissection. Thoracoscopy provides another means of accessing the mid to distal esophagus, while addition of this modality allows for… Continue Reading

Comparative analysis on clinical outcomes between laparoscopic distal pancreatectomy and open distal pancreatectomy : single center, single operator, same period experience
Purpose) Laparoscopic pancreatic surgery on distal lesion is in development state now. However benefit of laparoscopic distal pancreatectomy over the open surgery is not well known yet. We compared the clinical data of the patients underwent laparoscopic distal pancreatectomy (LDP group) with the patients underwent open surgery (ODP group) on the base of same operator,… Continue Reading

Comparison of oncological outcomes after laparoscopic transhiatal esophagectomy and open esophagectomy for pT1 esophageal adenocarcinoma
INTRODUCTION: This study compared pathological characteristics and patterns of disease recurrence for patients with pT1 esophageal adenocarcinoma treated with either laparoscopic transhiatal esophagectomy or open esophagectomy (Ivor Lewis or transhiatal).METHODS: Case notes were reviewed for consecutive patients, who had esophagectomy with pT1 adenocarcinoma at final pathological staging, during January 2000-December 2006. No patient had neo-adjuvant… Continue Reading

Composite Analysis of Surgical Review Corporation Bariatric Surgery Centers of Excellence Hospitals
Introduction: Surgery is currently the only effective long-term therapy for morbid obesity and its complications. A variety of surgical procedures can now offer durable and safe weight control as well as previously unrealized full remission of costly co-morbidities. This is a preliminary investigation of patient outcomes at Bariatric Surgery Centers of Excellence (BSCOE) Hospitals. Methods… Continue Reading

CyberDome, novel 3-dimension hemispherical display system, improves procedures of laparoscopic surgery
(Background) Despite of current advances with technology associated with laparoscopic surgery, laparoscopic surgeons still need a long experience to overcome the lack of depth perception on a 2-dimensional (2D) display. Although it was reported over two decades that 3-dimensional (3D) imaging provided depth perception and might improve laparoscopic procedures, 3D systems have not been widely… Continue Reading
Deconstructing Operative Flow – a Focus on Anticipatory Movements
Introduction: Efficient instrument movement is a vital part of a well-coordinated operating environment, and is a reflection of optimized ergonomic and human factor issues. In order to make assessments of these movements, objective, reproducible metrics are needed. In this study, instrument flow analysis is utilized to characterize anticipatory movements of the operative team.Methods: Five laparoscopic… Continue Reading
Development of minimally invasive surgery in infants less than 5kg: The first decade’s experience
Introduction: Pediatric minimally invasive surgery (MIS) has undergone significant development over the last 10 years but the role in complex neonatal and infant surgery is still being evaluated.. Technical advances and new procedures have allowed the evolution of MIS in even the smallest neonates. This report documents our experience in MIS in infants under 5kg.Methods:… Continue Reading

Directed Submucosal Tunneling for Transgastric NOTES Procedures
Background: Prior natural orifice translumenal endoscopic surgery (NOTES) work has shown the feasibility and the advantages of obtaining peritoneal access by using a tunneled translumenal approach. Objective: We evaluated the feasibility of creating directed transgastric submucosal tunnels with the goal of positioning the endoscope in an in-line position with target abdominal locations. Methods: We obtained… Continue Reading

Do Hybrid Simulator-generated Metrics Correlate with Content Valid Outcome Measures?
Objective: Hybrid simulators provide objective metrics for laparoscopic task performance. The aim of this study was to evaluate the correlation between hybrid simulator-generated metrics and content valid outcome measures.Methods and Procedures: Residents underwent training with a previously validated 5-task simulation model (5-TSM). Tasks included: clip/divide vessel, excise lesion, loop appendectomy, mesh placement with tacks, and… Continue Reading

Does Access to Minimally Invasive Surgery Account for Racial Differences in Surgical Outcome
Introduction: Minority populations consistently demonstrate poorer medical and surgical outcomes. Given that surgery is a rapidly evolving field, we hypothesized that poorer surgical outcomes by black patients are related to lack of access to minimally invasive surgery (MIS). Methods: We used data from the Nationwide Inpatient Sample, a 20% stratified random sample of patients admitted… Continue Reading

Does Incision Length Have Any Impact on Short Term Benefits of Laparoscopic Colon Surgery?
INTRODUCTION: With the recent introduction of hand-assist devices in laparoscopic colorectal surgery, there is renewed interest in the impact of incision length. The aim of this study is to define the impact of incision length on short-term postoperative outcomes.METHODS: Consecutive patients undergoing laparoscopic left-sided colorectal resection by 4 surgeons from 4 different academic centers from… Continue Reading

Does Increasing Experience with Laparoscopic Colorectal Surgery Influence the Outcome of Complex Cases?
OBJECTIVES: To define major risk factors for intraoperative complications (IOC) in laparoscopic colorectal surgery, and to assess whether surgeon experience influences the outcomes of complex cases.METHODS: Consecutive patients undergoing laparoscopic colorectal procedures from 1991-2005 were analyzed from a prospectively-collected database. All patients referred to the four surgeons involved in this study were offered a minimally… Continue Reading

Dysregulation of Gene Expression within the PPAR pathway in Obese Patients
Background: The causes of obesity are multifactorial and may include dysregulation of certain genes, such as peroxisome proliferator activated receptor gamma (PPAR gamma). When activated, the PPAR gamma pathway promotes lipid metabolism. This study uses microarray technology to evaluate differential gene expression profiles in obese patients undergoing bariatric surgery versus non-obese controls. Methods: Blood samples… Continue Reading

Early Experience with Transgastric NOTES Cholecystectomy in Humans
Natural orifice transluminal endoscopic surgery has enjoyed an accelerated development, going from theory to clinical application in less than 4 years. Early concepts of NOTES procedures seldom included cholecystectomy as it was considered too complex and challenging to approach with current technology. An unprecedented evolution of flexible endoscopes and endoscopic tools changed this and currently… Continue Reading
