VATS Vagotomy for the treatment of Chronic Marginal Ulcer
Background:Gastric Bypass is an increasingly common procedure. Associated rare complications have a related increased occurrence. Marginal ulceration at the gastrojejunal anastomosis has a reported incidence of 5 to 12%. In most instances these ulcers can be managed conservatively using acid suppression with proton pump inhibitors and sucralfate. There is a troublesome subset of this population,… Continue Reading

Validation that a one-year fellowship in minimally invasive/bariatric surgery can eliminate the “learning curve” for laparoscopic Roux-en-Y gastric bypass (LRYGB): Fellows’ first 100 cases in practice replicate the quality of their training institution.
INTRODUCTION: The concept that advanced surgical training can reduce or eliminate the “learning curve” for complex procedures makes logical sense but is difficult to verify and has not been tested for LRYGB. We sought to determine if minimally invasive / bariatric surgery fellowship graduates would demonstrate complication-related outcomes (CRO) equivalent to the outcomes achieved during… Continue Reading

Validation of Laparoscopic Surgical Skills Training Outside the Operating Room: A Long Road
Intro: Surgical skills training outside the OR is beneficial. The best methods have yet to be identified. In a series of three studies, we attempted unsuccessfully to document predictive validity of simulation training. Methods: In each study we used Global Operative Assessment of Laparoscopic Skills (GOALS) to evaluate operative performance 1.) Prospective, randomized, multi-center trial… Continue Reading

Validation of a Simple Camera Navigation Trainer
IntroductionA common challenge during laparoscopic surgery is proper usage of the 30 degree laparoscope. Optimal images are obtained by adjusting both the axis of the scope and the angle of lens as determined by the orientation of the light cord. Hence, utilizing a novice as the primary camera operator often results in a frustrating and… Continue Reading

Vagal Blocking for Obesity Control (vbloc) : Interim Six Month Results in an Ongoing Trial Using a Second Generation System
BACKGROUND: A new therapy (VBLOC) that intermittently blocks both vagi near the esophagogastric junction using high-frequency electrical algorithms has been reported to lower excess weight 14.2 (+/-) 2.2% in obese subjects as part of an earlier 6 month feasibility trial. The therapy is delivered by laparoscopically implanted electrodes. The proposed mechanisms for weight loss are… Continue Reading

Utilization of the Intragastric Balloon (bib) in Pre-operative Preparation for Super Obese Patients with High Surgical Risk Comparing with Two Steps Surgery.
Background: Super obese patients show a high surgical risk (major complications in 30% and mortality rate of 5-12%). The present study evaluates the use of BIB as a preoperative procedure aiming an initial weight loss and reduction of surgical risk. Methods: From November 2000 to February 2006, 66 super obese patients (mean BMI= 60.3 ±… Continue Reading

Utilization of Laparoscopic and Open Inguinal Hernia Repair
BACKGROUND: Laparoscopic inguinal hernia repair is a safe and effective treatment for inguinal hernias, and is considered by some to be the procedure of choice for recurrent inguinal hernias. Little is known, however, about the frequency with which laparoscopic inguinal hernia repair is performed and the determinants of its utilization.METHODS: We performed a retrospective cohort… Continue Reading

Utility of Drainage Catheters for Gastrojejunal Leaks After Laparoscopic Roux-en-Y Gastric Bypass: A Retrospective Review of 434 Cases
BACKGROUND: A leak at the gastrojejunal anastomosis (GJ) is a well recognized and occasionally fatal complication of obesity surgery. Closed suction drains have been routinely placed in the region of the GJ at the time of laparoscopic Roux-en-Y gastric bypass (LRYGBP) in order to aid in the recognition and treatment of such leaks. However, drains… Continue Reading

Using the Cellular Space for Telemedicine Applications-First Remote Presence Sessions
Introduction: Telemedicine applications are necessary developments in today’s “stressed” healthcare environment. Remote Presence® applications for tele-rounding and tele-mentoring using the Wireless Local Area Network-WLAN (802.11) portion of the radio-frequency spectrum and the public internet, have been previously reported by our group. This report documents the first use of a different part of the spectrum, the… Continue Reading
Using a Dynamic Training Environment to Assess Laparoscopic Skill
Current physical laparoscopic surgical simulators contain only static tasks, which do not develop the advanced hand-eye coordination skills needed to navigate the dynamic surgical environment. A dynamic minimally invasive training environment (DynaMITE) was developed to fill this need. Preliminary testing showed a potential for the device to improve the hand-eye coordination skills of even expert… Continue Reading
Usefulness of real-time blood vessel detectable forceps for lymph node dissection for training qualified laparoscopic surgeons
Aims: In the clinical education of recently qualified laparoscopic surgeons who have been trained only with simulation models, it is important to make them precisely localize the blood vasculature when conducting lymph node dissection in laparoscopic colectomy and gastrectomy. We developed a Doppler forceps with a foot controller that allows the detection of the blood… Continue Reading

Use of Routine Intraoperative Endoscopy in Elective Laparoscopic Colorectal Surgery – Can It Further Avoid Anastomotic Failure?
Background: Anastomotic leakage, bleeding and local recurrence remain serious complications of laparoscopic colorectal surgery. We aimed to study the usefulness of routine intraoperative endoscopy (RIOE) in elective laparoscopic colorectal surgery with distal anastomosis to predict postoperative anastomotic failure. Method: A retrospective review of 244 consecutive patients between January 2004 and May 2007 was performed. While… Continue Reading

Use of Magnets in Laparoscopic Cholecystectomy with Only One Port
Our surgical group has performed laparoscopic cholecystectomy with a single port since 10 years ago using needles instead of attendance ports. From May to August of 2007, we have used in selected cases (5 cases), magnets for traction of the gallbladder fundus as an alternative for the use of the reins and to improve the… Continue Reading
Use of Endoluminal Therapies for Obese Patients with GERD
Introduction: Body mass index > 30 is a preoperative predictor of failure after antireflux surgery, limiting therapeutic options for obese patients with medically refractory GERD. This study seeks to evaluate outcomes after two different endoluminal GERD therapies for these patients.Methods: Obese patients (BMI>30) presenting with medically-refractory GERD underwent either a single endoscopic full thickness (EFT)… Continue Reading
