Schwannomas are usually benign tumors arising from Schwann cells of the peripheral nerve sheath. Most schwannomas are benign, although malignant cases are known to occur. Retroperitoneal schwannoma is a rare entity comprising only 0.5% to 12% of all retroperitoneal tumors. In the retroperitoneal position, they occur most commonly between 40 and 60 years of age, […]
Background: Although there is data in the literature about the safety and efficacy of laparoscopic liver resections, there are not many studies comparing laparoscopic versus open approaches in a case-matched design. The purpose of this study is to compare the perioperative outcome of laparoscopic versus open liver resections from a single institution.Methods: Twenty-two patients underwent […]
Objectives: The goal of our study was to determine the safety and durability of an endolumenal plication of the stomach. Methods and Procedures: Ten 25-kg female swine underwent standard upper endoscopy, during which a single, 12 mm intragastric laparoscopic trocar was placed. Using the EndoStitch device (U.S. Surgical), an 8cm gastric sleeve was created by […]
BACKGROUND: Understanding abdominal wall thickness (AWT) is a key to optimal trocar design and enhancing surgical workspace layout, with a view to developing low profile laparoscopic ports, reducing clutter, and improving operative workflow. In order to establish a knowledge base upon which design can build, we measured AWT at the point of trocar insertion. METHODS: […]
Objective of the Technique: To introduce a novel technique for mesh placement during laparoscopic GPH repair. Recent data support the use of prosthetic mesh in the repair of large (>5cm) paraesophageal hernias, with decreased recurrence rates compared to primary repair. There is no consensus, however, as to the optimal type and shape of mesh, or […]
