Plasma Levels of Svegfr2 Are Decreased and Svegfr1 Increased Early After Colectomy for Cancer; the Net Impact Is Decreased Binding of Free Vegf Which May Account for Increased Plasma Vegf Levels Early Postoperatively
Purpose : Plasma VEGF levels are elevated after minimally invasive colon resection (MICR) and may pose a danger for colon cancer (CRC) patients. It is thought that surgical wounds produce VEGF which enters the circulation. VEGF induces angiogenesis in wounds and tumors by binding to endothelial cell bound VEGF-Receptor 1 (VEGFR1) and VEGF-Receptor 2 (VEGFR2).… Continue Reading

Poor Outcomes After Laparoscopic Adjustable Gastric Band
Background: Recent studies document EWL >50% for the laparoscopic adjustable gastric band (LAGB). This study reviews the LAGB experience at an urban academic center regarding complications, re-operative rate, and co-morbidities. Methods: 146 consecutive patients undergoing LAGB from August 2005 to December 2007 were reviewed. Pre and postoperative data were collected including weight, BMI, EWL, co-morbidities,… Continue Reading

Port Site Local Anesthetic Injection Does Not Decrease Postoperative Pain Level or Narcotic Use: A Randomized Blinded Study
Introduction:Trocar-site pain is a common complaint following laparoscopic cholecystectomy (LC). The purpose of this study was to determine whether local anesthetic use at trocar sites during LC decreases post-operative pain; and whether the timing of anesthetic injection influences this outcome. Methods and Procedures:After IRB approval, patients were randomized in a blinded fashion into four groups;… Continue Reading

Portal Vein Thrombosis After Laparoscopic Splenectomy for Massive Splenomegaly
Background Laparoscopic splenectomy has become the surgical procedure of choice in the therapy of various hematologic diseases. Portal vein thrombosis (PVT) is a well known complication of splenectomy, but the true incidence is not well established with several reports of up to 50% incidence. Massive splenomegaly is considered a risk factor for developing post operative… Continue Reading

Post-operative Gastric Bypass Marginal Ulcers and Strictures Lead to Increased Weight Loss
IntroductionMorbid Obesity is the leading public health epidemic of the industrialized world with bariatric surgery as the only effective and enduring treatment for this disease. Gastric Bypass is known to be very effective for weight loss but can have complications like marginal ulcers or strictures. We hypothesized that gastric bypass patients with ulcers/strictures have differing… Continue Reading

Posterior Partial Fundoplication Provides Good Control of Reflux with a Low Incidence of Mechanical Complications: A Prospective Review.
Introduction: Laparoscopic Nissens fundoplication is the most common surgical procedure performed for gastroesophageal reflux disease (GERD). It is however associated with a number of mechanical complications with as many as one in three patients experiencing troublesome dysphagia or gas bloat . Partial fundoplication, either posterior or anterior, has been advocated in an attempt to reduce… Continue Reading

Posterior Retroperitoneoscopic Adrenalectomy in Large Adrenal Tumors: A Comparison to the Standard Anterior Laparoscopic Technique
Background: Posterior retroperitoneoscopic adrenalectomy comprises an alternative option in minimally invasive adrenal surgery. Since the main contraindication to the retroperitoneal access seems to be the presence of a large tumor mass, we prospectively compared the posterior endoscopic technique to the laparoscopic in a case-controlled setting.Patients: From May 2008 to September 2008 eleven patients with large… Continue Reading

Pre-operative Warm-up Using Simulators. Duration of Effectiveness Decreases Over Time.
Previous randomized controlled double-blind studies have validated that practicing on a specifically designed simulation on a laptop will improve both cognition and psychomotor skills such that there is a reduction in errors and a decrease in operating time on an simulated surgical procedure. This study examines for how long the duration of improved performance following… Continue Reading

Predicting Marginal Ulcers After Laparoscopic Roux En Y Gastric Bypass
BACKGROUND: Marginal ulcer formation after Laparoscopic Roux en Y Gastric Bypass (LRYGB) is a known complication. Few studies have clearly identified risk factors and recommendations for prophylaxis have been controversial. METHODS: From July 2001 until January 2006, 764 patients underwent LRYGB for morbid obesity. Prospectively collected data were reviewed and demographic information, co-morbidities, and Body… Continue Reading

Predicting That Occult Metastatic (stage Iv) Disease Will Be Discovered with Diagnostic Laparoscopy and Peritoneal Lavage Cytology in Locally-Advanced Pancreatic Cancer
Background: In a group of 74 patients where computed tomography (CT) showed locally extending but not metastatic pancreatic cancer, we have demonstrated (Surg Endosc 2005;19:638-42) that 1/3 will have occult metastatic disease using diagnostic laparoscopy and peritoneal lavage for cytology (DL-PLC). Using a larger cohort, we asked if there are predictive factors that increase the… Continue Reading

Predictive Value of Computerized Tomography Scan on Conversion in Laparoscopic Surgery for Diverticulitis
Computerized tomography scan (CT) is an important tool in evaluation and assessment of diverticulitis disease. Previous Studies demonstrated different approaches depending on CT scan findings, which vary from clinic treatment to guided drainage or even urgent surgery.The aim of this study was to find out if CT findings have any predictive value for conversion in… Continue Reading

Predictors of Mortality in Laparoscopic Foregut, Hindgut and End-organ Surgery
INTRODUCTION A number of studies have identified predictors of perioperative mortality for open surgery and include variables such as ASA score, ascites, electrolyte abnormalities, and surgeon experience. In comparison, predictors of 30-day mortality in patients undergoing laparoscopy have yet to be defined. This study aims to identify factors predictive of 30-day mortality in patients undergoing… Continue Reading

Preoperative Angulation of the Distal Esophagus and Outcome After Heller Myotomy and Anterior Fundoplication for Achalasia
Introduction: Achalasia is defined by esophageal dysmotility and obstruction. Over time, obstruction may result in esophageal elongation and angulation of the distal esophagus. The aim of this study was to determine if preoperative distal esophageal angulation correlates with symptom relief after laparoscopic Heller myotomy and anterior fundoplication. Methods: 63 patients undergoing laparoscopic Heller myotomy with… Continue Reading

Preoperative Endoscopy in the Evaluation of Patients Before Bariatric Surgery
BACKGROUND: This study evaluates the diagnostic yield of esophago-gastroduodenoscopy (EGD) before bariatric surgery and its influence on the planned surgery. METHODS: Endoscopy reports of all patients having undergone an EGD at our endosurgical unit were reviewed. We identified a non-consecutive series of morbidly obese patients that had an endoscopic evaluation before their primary bariatric procedure… Continue Reading
Preoperative Evaluation of the Accessory Hepatic Ducts in the Calot Triangle with the 3-dimensional CT Image of Cholangiogram (3d-dic-ct) to Avoid Its Injury At Laparoscopic Cholecystectomy.
Introduction: Bile duct injury is one of the common problems which should be avoided in the Laparoscopic cholecystectomy. Endoscopic retrograde cholangiogram (ERC) is useful to find them, but it force to the patient burden and pain for more than 20 minutes. For the sake, we have been trying to figure out clear 3 dimensional (3D)… Continue Reading
