CT Scan: An Effective Way to Measure Gastric Pouch´s Volume in Gastric Bypass
Introduction: Weight regain after bariatric surgery is a controversial issue. Some authors argue that this happens because of dilated gastric pouch, others because limb length, hormonal reasons etc. Concerning gastric volume, several procedures have been described to measure this volume. Three dimension CT scan is a reproductible and effective procedure to measure gastric volume. Objective:… Continue Reading

CT Scan As a Complementary Study for Colon Tumor Localization
Introduction: Our hypothesis is that a CT scan may complement colonoscopy in preop localization of colon tumors.Erroneous tumor localization via colonoscopy creates a challenging intraoperative problem for surgeons. The ideal method to minimize these errors is unclear. In this study, we have examined the ability of CT scans to properly localize colon lesions, and potentially… Continue Reading

Dedicated Laparoscopic Skills One Month Rotation for General Surgery Interns
Introduction: Laparoscopic skills acquisition is an important part of residency training. Early training may help with more advanced laparoscopic skills acquisition. Thus, we feel that laparoscopic skills should be taught to first year general surgery residents. This study investigated the hypothesis that a one month dedicated laparoscopic skills rotation would yield appropriate laparoscopic skill levels… Continue Reading

Deficiency of Knowledge in General Surgery Residents on Surgical Stapling Devices: The Role of a Focused Instructional Session
Introduction: There is a paucity of knowledge on the application and usage of common surgical stapling devices by general surgery residents. Our study aimed to elicit the deficiencies that exist in this particular area and assess a short term teaching strategy to determine if a didactic review of stapling devices would improve knowledge and skill… Continue Reading

Defining the Host Immune Response to NOTES
Before natural orifice translumenal endoscopic surgery (NOTES) can be safely introduced for human use in the United States, several technical and physiologic factors need to be elucidated. Among these are the host systemic and peritoneal responses to inflammation. The inflammatory response to laparoscopy (LAP) has been well characterized, and has been shown to favorably alter… Continue Reading

Detail Analysis of Vessel Sealing Perfomance of Bipolar Vessel Sealing System for Laparoscopic Surgery
INTRODUCTION: Vessel sealing devices of 5 mm in diameter for laparoscopic surgery provide only a small breadth of sealing area. Therefore, various double sealing techniques have been tried to enhance bursting pressure of the sealed vessels by surgeons. However, there have been no reports to reveal which technique achieved best performance of vessel sealing. Those… Continue Reading

Development and Validation of Mental Practice As a Training Strategy for Laparoscopic Surgery
BackgroundConcerns for patient safety have rendered the need for alternative training strategies outside of the operating-theatre. Mental Practice (MP), ‘the cognitive rehearsal of a task prior to performance,’ has been successful in sport and aviation to enhance imagery and thus skill. This study aims to develop and validate a MP training strategy for laparoscopic surgery.MethodA… Continue Reading

Development of a New Computer Aided Diagnosis System to Detect Lymph Nodes in the Abdomen: Further Utility for Sentinel-node Navigated Laparoscopic Surgery in Gastrointestinal Cancers and Its Education.
Introduction: Preoperative imaging is highly useful to make a planning of operation and preoperative simulation. Recently, sentinel-node navigated surgery has been advocated in gastrectomy for gastric cancer to minimize surgical stress without curability. Little has been reported about computer aided diagnosis system (CADS) to detect lymph nodes (LNs). We herein introduce our new CADS. Methods:… Continue Reading

Development of a Pancreatic Tumor Animal Model and Assessment of Feasibility of NOTES™ Tumor Enucleation As a Multidisciplinary Approach – a Noscar™-funded Project.
BACKGROUND: Laparoscopic distal pancreatectomy is associated with a high morbidity and mortality. We could demonstrate the feasibility of endoscopic transgastric distal pancreatectomy in the porcine animal model. NOTES tumor enucleation may provide an alternative to distal pancreatectomy. The goal of this study was to determine the feasibility of NOTES tumor creation and enucleation as a… Continue Reading

Dexterous Robot for Single Incision Advanced Minimally Invasive Surgery
Introduction: This study demonstrates the feasibility of using a miniature robot platform to perform complex, single-incision, minimal access surgery, including colon resection and Nissen fundoplication. Open surgical procedures are highly invasive; single-incision laparoscopic surgery is complicated by instrument position and lack of triangulation. Using minimally invasive techniques with miniature robotic platforms offers significant clinical benefits.… Continue Reading

Diagnosis, Treatment, and Outcomes of Duodenal Neoplasms
Duodenal neoplasms are rare and range from benign lesions that can be treated with endoscopic techniques to adenocarcinoma that often requires surgical resection. The purpose of this project was to evaluate the incidence, diagnosis, treatment, and outcomes of duodenal neoplasms at a large tertiary-care hospital. A retrospective review was conducted (2002-2007). Patients were identified from… Continue Reading

Diagnostic Transgastric Endoscopic Peritoneoscopy: Extension of Initial Human Trial for Staging of Pancreatic Head Masses
OBJECTIVE(S): We validated Natural Orifice Translumenal Endoscopic Surgery (NOTES) in a human trial of ten patients undergoing diagnostic transgastric endoscopic peritoneoscopy (DTEP) for staging of pancreatic head masses. Reported herein is an update with 10 additional patients.METHODS: Patients in this IRB approved human trial were scheduled to undergo diagnostic laparoscopy for abdominal staging of a… Continue Reading

Different Approaches for Laparoscopic Adrenalectomy Looking for a Tailored Route
Aim: to report our experience in laparoscopic adrenalectomy (LA) through anterior, lateral and submesocolic approaches .Methods: 267 patients (pts) underwent LA in our departments. The choice of the surgical route was based on patient (BMI, previous abdominal surgery) and lesion features (size, side, secreting mass, suspect malignancy). Dissection and coagulating technology did change over the… Continue Reading

Differential Expression of Mmp-2 in the Gastrohepatic Ligament of the Gastroesophageal Junction
Introduction: Ligamentous attachments maintain the normal anatomical position of the gastroesophageal (GE) junction. Failure of these elastic ligaments through an alteration in collagen synthesis, deposition and metabolism may be a primary etiology of hiatal hernia formation. Differential expression of zinc-dependent matrix metalloproteinases (MMPs) is largely responsible for collagen remodeling. The purpose of this study was… Continue Reading
