Long-term Improvement of Pulmonary Function after Laparoscopic Gastric Bypass Surgery
INTRODUCTION: Morbidly obese patients often have impaired respiratory mechanics leading to restrictive lung disease. Weight loss after bariatric surgery has been shown to improve or resolve many obesity-related comorbidities; however, little is know about the long-term changes in pulmonary mechanics after bariatric surgery. We hypothesize that pulmonary function may improve with weight loss after laparoscopic… Continue Reading

Long-term quality of life after laparoscopy-Assisted distal gastrectomy
Background : Laparoscopy-assisted distal gastrectomy (LADG) needs longer@operation time, but brings lesser pain, invasiveness after operation compared with open distal gastrectomy (ODG). Patients undergone LADG can recover earlier than ODG. However comparative study of long-term quality after LADG and ODG is not performed.Patients and Method : From August 2007 to July 2006, 197 patients with… Continue Reading

Magnetic Retraction for NOTES Transvaginal Cholecystectomy
Introduction: Natural orifice surgery (NOTES) has the potential to decrease the burden of an operation on a patient. Limitations of the endoscopic platform require innovative solutions to provide retraction and create an operation comparable to the gold standard, laparoscopic cholecystectomy. Methods: Four patients underwent transvaginal cholecystectomy. All procedures were performed under laparoscopic vision to ensure… Continue Reading

Maximizing the donor pool: Use of right kidneys and multiple arteries for live donor kidney transplantation
Introduction: The first laparoscopic donor nephrectomy (LDN) was performed in 1996. Since that time, LDN is becoming standard of care for organ procurement. Donor and recipient outcomes have been proven equivocal for laparoscopic and open nephrectomy. In the past, LDN was avoided when procuring the right kidney or organs with multiple arteries. Reviewing our experience… Continue Reading

Mechanisms of Ventral Hernia Recurrence Following Laparoscopic Repair
Objective: To determine mechanisms of ventral hernia recurrence following laparoscopic repair.Background: Laparoscopic ventral hernia repair techniques have demonstrated low recurrence rates in recent years. Mechanisms of recurrence following open repair are well-documented, but there is less data defining how laparoscopically-repaired hernias recur.Methods: We performed a retrospective analysis of 25 patients who had previously undergone at… Continue Reading

Mesh Complications after Prosthetic Reinforcement of Hiatal Closure. A 29 Case Series.
Background:Primary laparoscopic hiatal hernia repair is associated with up to a 42% recurrence rate. This has lead to the use of mesh for crural repair, which has resulted in an improved recurrence rate (0-24%). However, mesh complications have been reported. Methods:We compiled three cases and our senior author contacted other experienced esophageal surgeons who provided… Continue Reading

Minimally invasive colon resection is associated with increased sVEGFR1 and decreased sVEGFR2 plasma levels early after surgery; the net impact is decreased binding of free VEGF which may account for increased plasma VEGF levels early post surgery
Introduction: Plasma VEGF levels are increased after minimally invasive colorectal resection (MICR) for both benign and malignant disease. VEGF, which is critical to both wound healing and tumor growth, induces angiogenesis by binding to endothelial cell bound VEGF-Receptor 1 (VEGFR1) and VEGF-Receptor 2 (VEGFR2). Soluble VEGF-Receptor-1 (sVEGFR1) and soluble VEGF-Receptor-2 (sVEGFR2), which are not capable… Continue Reading

Minimally Invasive Ivor-Lewis Esophagogastrectomy for Gastric Cardia Cancer
Introduction: Gastric cardia cancer with involvement of the esophagus may require an esophagogastrectomy to obtain negative tumor margins. We have shown that minimally invasive esophagectomy is a safe approach for the treatment of esophageal cancer. We describe the technique of a minimally invasive Ivor Lewis esophagectomy in a patient with a large gastric cardia tumor.Methods:… Continue Reading

Morbidly Obese Patients Do Not Have Increased Incidence of Early Recurrence After Laparoscopic Ventral Hernia Repair
INTRODUCTION: Previous studies have raised concern that morbid obesity is associated with a markedly increased risk of recurrence after repair of ventral hernias. This study compared the incidence of early post-operative recurrence after laparoscopic ventral hernia repair in morbidly obese patients and non-morbidly obese patients.METHODS: Case notes were reviewed for consecutive patients who underwent laparoscopic… Continue Reading

Multicenter study of laparoscopic surgery for colon cancer in Japan
Objective: To evaluate short and long-term results of laparoscopic surgery for colon cancer, we conducted a nationwide survey and prospective randomized controlled trial (RCT) in Japan, supported by Grants for Clinical Cancer Research from the Ministry of Health, Labor and Welfare in Japan.A retrospective nationwide survey: The study group comprised 2036 patients undergoing laparoscopic surgery… Continue Reading

Natural Orifice Cholecystectomy Using a Miniature Robot
Introduction: Natural Orifice Translumenal Endoscopic Surgery (NOTES) is surgically challenging. Current endoscopic tools provide an insufficient platform for visualization and manipulation. This study demonstrates the feasibility of using a miniature in vivo robot to enhance visualization and provide off-axis dexterous manipulation capabilities for NOTES. Methods: We developed a dexterous, miniature robot with six degrees-of-freedom capable… Continue Reading

Natural Orifice Transesophageal Mediastinoscopy and Thoracoscopy: A Survival Series in Swine
Introduction: Mediastinoscopy (MX) and thoracoscopy (TX) are common procedures with painful incisions and prominent scars. A natural orifice transesophageal endoscopic surgery (NOTES) approach could reduce pain, eliminate intercostal neuralgia, provide access to the posterior mediastinal compartment or hilum, and improve cosmesis. The purpose of this study is to create a survival animal model for NOTES… Continue Reading

Natural Orifice Translumenal Endoscopic Drainage for Pancreatic Abscesses
INTRODUCTION: Endoscopic pseudocyst drainage is well documented, but few series describe endoscopic drainage of pancreatic abscesses. Abscesses are complications of pancreatitis, presenting with sepsis and/or peritonitis. We report the feasibility and efficacy of natural orifice translumenal endoscopic surgery for pancreatic abscesses. METHODS: We reviewed consecutively treated patients (1994-2007). Approaches alone or in combination were: (1)… Continue Reading

Natural Orifice Translumenal Endoscopic Surgery with a Miniature in Vivo Surgical Robot
Introduction: The application of flexible endoscopy tools for Natural Orifice Translumenal Endoscopic Surgery (NOTES) is constrained due to limitations in dexterity, instrument insertion, navigation, visualization, and retraction. Miniature endolumenal robots that are not constrained by the natural orifice can mitigate these constraints through providing a stable platform for visualization and dexterous manipulation. This video demonstrates… Continue Reading

Near total laparoscopic pancreatic resection for chronic pancreatitis
In the past, a minimally invasive technique in pancreatic surgery was only used for diagnostic laparoscopy in evaluating periampullary malignancy. Recent advances in operative techniques and instrumentation have empowered surgeons to perform all procedures in the pancreas surgery, including the Whipple procedure. Some of these tecniques represent the most sophisticated application of minimally invasive surgery.A… Continue Reading
