Laparoscopic sleeve gastrectomy (LSG) remains under scrutiny as a stand-alone bariatric procedure. The most feared complication after LSG is staple line leak. Eight bariatric centers in Israel participated in this study. A retrospective analysis was performed by querying all the LSG cases performed between June 2006 and June 2010. The data collected(More)
Early detection of colorectal cancer (CRC) is currently based on fecal occult blood testing (FOBT) and colonoscopy, both which can significantly reduce CRC-related mortality. However, FOBT has low-sensitivity and specificity, whereas colonoscopy is labor- and cost-intensive. Therefore, the discovery of novel biomarkers that can be used for improved CRC(More)
BACKGROUND The principal role of sentinel lymph node (SLN) sampling and ultrastaging in colon cancer is enhanced staging accuracy. The utility of this technique for patients with colon cancer remains controversial. PURPOSE This multicenter randomized trial was conducted to determine if focused assessment of the SLN with step sectioning and(More)
Torsion of an accessory spleen is extremely rare. We report a case of an acute torsion of an accessory spleen in a young patient who presented with acute left abdominal pain and discuss the computed tomographic findings of this exceptional condition. Awareness of this entity and familiarity with typical imaging findings are mandatory for preoperative(More)
Obstruction of the small intestine is a recognized complication after Roux-en-Y gastric bypass surgery for morbid obesity. Reported causes after bariatric surgery include volvulus, adhesion, internal hernia, hemorrhagic bezoar, incarcerated ventral hernia, and intussusception. Intussusception after Roux-en-Y gastric bypass for morbid obesity is rare. The(More)
BACKGROUND Uniform and accurate reporting of surgical complications is the basis for quality control. We developed a computerized system for reporting and grading surgical complications in colorectal surgery. This study was conducted to evaluate this computerized reporting system. STUDY DESIGN A retrospective chart review was conducted of all surgical(More)
Intraoperative ultrasonography (US) is used in many centers before oncologic liver resections to detect additional tumors and to evaluate the relationship of tumors to major vascular structures. As preoperative imaging improves, it is expected that the diagnostic yield from intraoperative US will diminish. In this study we attempt to determine if fewer(More)
Laparoscopic sleeve gastrectomy (LSG) has grown in popularity in recent years for the treatment of morbid obesity. Controversy exists regarding the usefulness of upper gastrointestinal (UGI) swallow studies on the first postoperative day in detecting possible complications. The aim of our study was to determine the efficacy and cost benefit of routine UGI(More)
BACKGROUND Long non-coding RNAs (lncRNAs) have been shown to have functional roles in cancer biology and are dys-regulated in many tumors. Colon Cancer Associated Transcript -1 (CCAT1) is a lncRNA, previously shown to be significantly up-regulated in colon cancer. The aim of this study is to determine expression levels of CCAT1 in gastric carcinoma (GC). (More)
To investigate the contributions of two surgical gut manipulations-exclusion of the proximal intestine from alimentary flow and exposure of the jejunum to partially digested nutrients-to body weight regulation and metabolism, we have developed a rat model of an investigational device, the endoluminal sleeve (ELS). The ELS is a 10 cm, nutrient-impermeable,(More)
