Peroral Endoscopic Submucosal Pyloromyotomy in In Animal Model for a New Concept of Minimally Invasive Surgery for Pyloric Stenosis
BACKGROUND: In current therapeutic strategies, pyloric stenosis is managed by open or laparoscopic myotomy. Thanks to recent improvements in flexible endoscopic instrumentation and techniques, totally peroral endoscopic approaches could reduce the invasiveness of the procedure. The aim of this study is to establish the feasibility and efficacy of endoscopic submucosal pyloromyotomy in a nonsurvival porcine… Continue Reading

Physicomechanical Evaluation of Absorbable and Nonabsorbable Barrier Composite Meshes for Laparoscopic Ventral Hernia Repair
INTRODUCTION: The objective of this study was to compare the physicomechanical properties of composite prostheses with both absorbable and nonabsorbable barriers. The primary function of these barriers is to prevent adhesion formation. It is unknown how these barriers affect the physicomechanical properties of the prostheses. Seven composite prostheses commonly utilized for laparoscopic ventral hernia repair… Continue Reading

Pictorial Documentation of Laparoscopic Cholecystectomy
Introduction: Concerns have been raised as to how to maintain pictorial documentation of an interesting finding during laparoscopic cholecystectomy (LC). We believe that documentation of surgery is of essential benefit, especially if a complication arises. In addition, documentation may be utilized for future reference for patient care. Methods: We reviewed the pictorial documentation of 100… Continue Reading

Plasma Levels of Placenta Growth Factor (plgf), a Proangiogenic Protein, Are Elevated for 3 Weeks After Minimally Invasive Colorectal Cancer Resection
Introduction: Placenta Growth Factor (PlGF) is a key protein in the “angiogenic switch” in the pathologic setting that stimulates tumor growth via modulation of VEGF’s effects and via inhibition of apoptosis. Plasma VEGF levels are elevated for weeks after minimally invasive colorectal resection (MICR) and may encourage residual tumor to grow. The purpose of this… Continue Reading

Plasma Soluble Vascular Adhesion Molecule-1 Levels Are Persistently Elevated During the First Month After Colorectal Cancer Resection
Introduction: Human Vascular Cell Adhesion Molecule -1(VCAM1) is a 110 kDa transmembrane glycoprotein expressed in vascular endothelial cells (EC), neurons, fibroblast and macrophages. Expression is regulated by inflammatory cytokines such as IL-1, TNFalpha, IL-4 and IL-13. Soluble VCAM-1 (sVCAM-1) is made when the extracellular part of VCAM-1 is shed from the cell surface into the… Continue Reading

Playing Nintendo® Wii™ Improves Virtual Reality Laparoscopic Simulator Performance
Background: Video games have been shown to improve eye-hand coordination, spatial visualization, manual dexterity, and rapid mental processing, which are important in the acquisition of laparoscopic skills. The primary goal of this study was to determine whether or not playing a Nintendo® Wii™ video game (VG) would improve virtual reality (VR) laparoscopic surgery simulator performance.… Continue Reading

Pneumatosis Coli From Endoscopy: A Case Report
Recent advances in technology have expanded the use of endoscopy in the diagnosis and treatment of gastrointestinal conditions. The majority of endoscopic procedures are performed on the principle of air insufflating hollow organs. While perforation from increased intraluminal pressure is a known complication of endoscopy, pneumatosis from endoscopy is uncommon and has not been well… Continue Reading

Pneumoretroperitoneum: An Alternative Approach for Completion Adrenalectomy in a Hostile Abdomen
A 43-year-old woman developed morning headaches, sweating, palpitations and uncontrolled hypertension for 12 months. She was known to have Von Hippel-Lindau and had previously had a left adrenalectomy in 1995 (open anterior approach) and a partial right adrenalectomy in 2000 (open lateral approach). She required an exploratory laparotomy in 1991 for a gunshot wound to… Continue Reading

Polyester Composite Versus Ptfe in Laparoscopic Ventral Hernia Repair
Polyester Composite versus PTFE in Laparoscopic Ventral Hernia RepairIntroduction:Both polyester composite (PCO) and polytetrafluoroethylene (PTFE) dual meshes are commonly utilized for laparoscopic ventral hernia repair. Sparse information exists, however, comparing perioperative and long-term outcome by mesh repair. Methods:A prospective database was utilized to identify 116 consecutive patients who underwent laparoscopic ventral hernia repair at The… Continue Reading

Portable, Self-practice Laparoscopic Box Trainers Underutilized By Surgical Trainees
Background: Surgical skills training is becoming an integral part of general surgery residency programs. While the RRC and ACGME require access to a skills training laboratory, and the ACS and APDS offer a surgical skills curriculum template, there is no consensus as to what comprises a mandatory curriculum. The TASKit portable laparoscopic simulator (Cincinnati, OH)… Continue Reading

Post Colonoscopy Colonic Intussusception Reduced Via a Laparoscopic Approach: A Case Report
Colonic intussusception in adults is uncommon and intussusception after colonoscopy is rare. We present a case of colo-colonic intussusception that was successfully treated by laparoscopic reduction. In this case report, we identified a patient who presented to the emergency room with abdominal pain and radiographic evidence of intussusception. METHOD: A 32 year old healthy male… Continue Reading

Post-operative Chronic Pain and Recurrence Following Laparoscopic Inguinal Hernia Repair: To Staple or Not to Staple?
The purpose of this study was to review the experiences of a single surgeon who, over a 17-year period, performed a total of 3125 laparoscopic inguinal hernia repairs in 2540 patients. In the first 1700 repairs, the mesh was tacked and in the last 1425 repairs, the mesh was not tacked. We then compared the… Continue Reading

Posterior Vagus Nerve Within or Outside Nissen Fundoplication: Does It Matter?
Background: Laparoscopic Nissen surgery is the gold standard surgical treatment for gastro-esophageal reflux disease. Either one or both vagus nerves can be within or outside the fundoplication. The aim of this study was to determine if placing the posterior vagus nerve within or outside the fundoplication had any effect on patient symptom relief. Materials and… Continue Reading
