Surgically Created Taste Aversions Develop in Rats Following Roux-en-Y Gastric Bypass
Background: Effective non-surgical treatment of morbid obesity continues to elude the medical community. Capturing positive effects of Roux-en-Y gastric bypass (RYGB) without surgery may be essential in achieving this goal. We have previously shown that patients experience taste changes and aversions following RYGB. A rat model for RYGB can help define these changes as physiological… Continue Reading

Sustaining Laparoscopic Suturing Proficiency by Maintenance Testing
Introduction: Proficiency-based training for laparoscopic suturing has been shown to translate to improved performance in the OR. However, testing to maintain proficiency in resident training programs has not been established. The purpose of this study is to determine the efficacy of a maintenance testing curriculum for resident skill retention. Methods: Surgical residents, previously trained to… Continue Reading

Suture Survival in an Acidic Environment: Implications for Natural Orifice Transgastric Endolumenal Surgery (NOTES)
Background: Recent interest in translumenal approaches to conventional surgical procedures such as NOTES has reintroduced the question of what is the ideal suture material for visceral closure of enterotomy sites. With necessity of secure closure from transgastric approaches, a study was designed to test the hypothesis that there would be variable longevity of suture ligature… Continue Reading

Telerobotic Surgery for Foregut Operations: 61 Consecutive Cases – One Surgeon
Background: This study evaluated the feasibility of using robotic assistance for foregut surgery. It described the experience, advantages, and disadvantages of using the da Vinci system on the basis of 61 consecutive foregut cases by a minimally invasive, fellowship-trained surgeon. Methods: Data were collected on 61 consecutive foregut operations performed with the da Vinci system… Continue Reading
Telesimulation: A Novel Method of Teaching Fls in Africa
Objective: Telesimulation (TS) is a novel concept that uses the internet to link simulators between an instructor and trainee in different locations.The objective of this study was to determine if TS could be used to teach FLS from Canada to Botswana, Africa. Methods: Pre-test FLS scores were obtained for each surgeon during a first visit… Continue Reading

The AirSeal TM : A new insufflation system for laparoscopic Surgery. Preliminary data concerning physiological changes.
Introduction:The physiopathologic consequences of pneumoperitoneum are well known. In the attempt to minimize CO2 peritonel uptake and the related physiological consequences, a new generation of insufflation systems and trocars are in development. This experimental animal study aims to assess the applicability and safety of a new insufflation and trocar system for laparoscopic surgery: the AirSeal… Continue Reading

The Benefit of Esophageal Acid Control Before and After Radiofrequency Ablation of Barrett\’s Mucosa
Background:BAARX is one of several techniques used to ablate Barrett’s mucosa. Twenty four pH monitoring was used to assess the effect of acid control on the ablation technique in patients who had medical or surgical therapy for GERD.Methods:Seventeen consecutive patients with Barrett’s esophagus who underwent BAARX ablation between 2005 and 2007 were entered into a… Continue Reading

The Diagnosis of Gastroesophageal Reflux: Which is Correct; Multichannel Intraluminal Impedance or pH Monitoring?
Background: Accurate identification of gastroesophageal reflux episodes is fundamental to the objective diagnosis of GERD. The diagnosis of GERD by multichannel intraluminal impedance (MII) is based on the detection of retrograde bolus propagation, irrespective of its pH. It is suggested that both the number and duration of acidic reflux episodes varies depending on the method… Continue Reading

The Effect of Laparoscopic Staplers on Porcine Small Bowel Perfusion.
Introduction: Few studies have been designed to assess the performance of laparoscopic surgical staplers. This study analyzes the effect of staples and staple height on tissue perfusion. Methods: Staple lines created on live porcine small bowel segments using laparoscopic surgical staplers were tested for perfusion using visible light spectroscopy to assess tissue oxygenation. Perfusion measurements… Continue Reading

The Effects of Laparoscopic Cholecystectomy, Hysterectomy, and Appendectomy on Nosocomial Infection Risks
Background: This paper presents precise estimates of nosocomial infection risks associated with laparoscopic as compared to open surgery in three procedures: cholecystectomy, appendectomy, and hysterectomy.Methods: A retrospective analysis was performed on 11,662 admissions from 22 hospitals that have a nosocomial infection monitoring system. The Nosocomial Infection Marker (NIM, patent-pending) was used to identify nosocomial infections… Continue Reading

The effects of obesity by the learning curve for Laparoscopy Assisted Distal Gastrectomy in patient with early gastric cancer
Background. Laparoscopy-assisted distal gastrectomy(LADG) has become a viable alternative treatment for patients suffering with early gastric cancer. Surgeons have long thought that obesity might increase the rate of intraoperative or postoperative complications. We set out to clarify the effect that obesity has on performing LADG for the treatment of early gastric cancer.Methods. We retrospectively reviewed… Continue Reading
