Pulmonary Embolism in Laparoscopic Cholecystectomy
Introduction: Pulmonary embolism (PE) is a relatively uncommon complication following laparoscopic cholecystectomy (LC). When the abdomen is insufflated with CO2, increased intrabdominal pressure diminishes venous return causing potentially low cardiac output and venous stasis. Our study was to determine whether this phenomenon is significant enough to increase the risk of PE while performing LC. Methods:… Continue Reading

Quantitative Ergonomics Assessment of NOTES Techniques: A Study of Physical Workload, Body Movement and Posture
Introduction: This study investigates through biomechanical analyses NOTES and laparoscopic physical workloads. Research confirms that surgeons experience physical symptoms due to the unfavorable ergonomics of MIS performance. The ergonomics of NOTES—potentially the next evolutionary surgical step—is only now being quantitatively and systematically assessed Methods and Procedures: Six surgeons with varying MIS experience were recruited for… Continue Reading
Radical Transanal Endoscopic Microsurgey (tem): Endoluminal Surgery for Complex Rectal Lesions
Introduction: TEM represents the only longstanding approach to endoluminal surgery. Guidelines excluding large lesions and those that may require entry into the peritoneal cavity limit the applicability of TEM surgery. This study evaluates the feasibility, safety, and efficacy of radical application of TEM for the treatment of complex rectal lesions. Methods: From a prospective TEM… Continue Reading

Randomized Study Comparing Hemodynamic and Pulmonary Effects of Transgastric Endoscopic Surgery with the Insuflation of Co2 and Air.
INTRODUCTION: There is currently interest in further expanding the capabilities of flexible endoscopic surgery to accomplish procedures that presently require laparoscopic access. Natural orifice transluminal endoscopic surgery (NOTES) is a new and rapidly evolving hybrid procedure in which flexible endoscopic technology is used to perform intra-abdominal laparoscopic surgical procedures. Flexible endoscope based endoluminal surgical procedures… Continue Reading

Rare Case of Laparoscopic Repair of a Strangulated Obturator Hernia
Introduction: Obturator hernias are rare, comprising less than 0.1% of all hernias and occurring in approximately 0.4% of bowel obstructions. Typically these hernias affect elderly, frail, debilitated women; 85% of patients are female with mean age of 82 years and mean weight of 34.5 kg. Only 1 of 10 cases is correctly diagnosed preoperatively. The… Continue Reading

Real-time Fluorescence Imaging of Biliary Anatomy During Laparoscopic Cholecystectomy
Background: We evaluate real-time fluorescence imaging of biliary anatomy using indocyanine green (ICG) during laparoscopic cholecystectomy. Patients and Methods: This study enrolled eight patients who underwent laparoscopic cholecystectomy. ICG was injected 2 hours before exploration. Under general anesthesia, we observed biliary tract under the guidance of real-time fluorescence imaging produced by prototype laparoscope. The flow… Continue Reading

Real-time Intraoperative Detection of Tissue Hypoxia in Endoscopic Gastrointestinal Surgery By a Novel Wireless Pulse Oximeter (wipox)
ObjectiveDehiscence or leakage following bowel anastomoses occurs at a rate of 0-50% with a high associated mortality. Vascular perfusion and tissue oxygenation (SpO2) at the anastomotic site are fundamental determinates of anastomotic viability. We aimed to construct a wireless pulse oximeter (WiPOX) to monitor intraoperative real-time tissue oxygenation, permitting the identification of unrecognized compromised blood… Continue Reading
Reconstruction of the Anterior Abdominal Wall with Bilateral Endoscopic Component Separation, Laparoscopic Assisted Medialization of the Rectus and Laparoscopic Mesh Placement
Introduction:Standard laparoscopic repair of a large midline ventral hernia with mesh is frequently associated with seroma formation. In addition the rectus muscles cannot be medialized in large defects, thereby potentially leading to a less functional abdominal wall. We present a novel approach of repairing the midline abdominal wall defect while repairing the hernia laparoscopically with… Continue Reading

Recurrent Paraesophageal Hernia with Gastrobronchial Fistula: Laparoscopic Repair
Introduction: The optimal method to manage a second recurrence of a paraesophageal hernia and a simultaneous gastrobronchial fistula is debatable. This video demonstrates a laparoscopic approach to this complex revisional operation performed on a 62 year old female who presented to our office with this diagnosis.History: This patient’s surgical history began with a laparoscopic paraesophageal… Continue Reading

Reoperative Antireflux Surgery for Dysphagia
Background: Little is known regarding the predictors of favorable outcomes following re-do Anti-reflux surgery (Re-ARS). The aims of this study were: (1) to analyze the efficacy of Re-ARS in resolving dysphagia; and (2) to identify risk factors for persistent or new-onset dysphagia after Re-ARS. Methods: After IRB-approval, a prospectively maintained database was retrospectively reviewed to… Continue Reading

Reoperative Laparoscopic Paraesophageal Herniorraphy Can Produce Excellent Outcomes
Introduction: Patients undergoing laparoscopic paraesophageal herniorraphy, either initial or recurrent, present with a myriad of esophageal and extra-esophageal symptoms. Given an overall recurrence rate of approximately 8%, reoperative paraesophageal herniorraphy is necessary on a significant number of patients. The goal of this study is to determine whether patients proceeding with laparoscopic reoperative paraesophageal herniorraphy experienced… Continue Reading

Repair of a Hiatal Defect Using a Rotational Falciform Flap
Background: Closure of the hiatal defect in laparoscopic surgery of the foregut remains a challenging problem. Over the years, several materials have been used- varying compounds of nonabsorbable synthetics as well as absorbable biologic material. Yet, there is a high recurrence rate associated with primary closure and an unacceptably high rate of esophageal erosion and… Continue Reading

Repeated Laparoscopic Hepatectomy for the Recurrent Hepatocellular Carcinoma
We have pursued laparoscopic hepatectomy as a means of surgical therapy for hepatocellular carcinoma (HCC) since 1993. It has been reported that laparoscopic hepatectomy in the patient with HCC appears to be a viable surgical alternative providing less invasion in selected cases. This procedure is expected to develop further in the future as a new… Continue Reading
Results and Perspective to the Future in the Field of Laparoscopic Cholecystectomy of Japanese Endoscopic Surgical Skill Qualification System
Purpose: The Japan Society for Endoscopic Surgery (JSES) started Endoscopic Surgical Skill Qualification system (ESSQS) in 2003 in order to improve the safety of procedure, and carried out five examinations since 2004 up to 2008. We reported these 5 years’ results of cholecystectomy field in ESSQS. Methods: Assessment was performed by reviewing documents, laparoscopic surgery… Continue Reading

Results of Laparoscopic Repair of Primary and Recurrent Incisional Hernias At a Single Uk Institution
IntroductionLaparoscopic incisional hernia repair has been gaining increasing recognition with its perceived benefits of shorter hospital stay, decreased postoperative pain and the ability to diagnose and treat previously unrecognised defects at the time of operation. In this study incisional hernia repairs at a single UK institution between 1994 and 2008 were analysed with respect to… Continue Reading
