INTRODUCTION Long-term outcome of patients following conversion during laparoscopic surgery for colorectal cancer is not often reported. Recent data suggest a negative impact of conversion on long-term survival. This study aimed to evaluate the impact of conversion on the perioperative outcome and on long-term survival in patients who underwent laparoscopic(More)
BACKGROUND A grading system for postoperative complications is important for quality control and comparison among investigations. The objective of the current study was to evaluate complications associated with laparoscopic colorectal surgery according to a standardized grading system, and to examine risk factors associated with different complication(More)
BACKGROUND The effect of anti-platelet drugs on surgical blood loss and perioperative complications has not been studied in depth and the management of surgical patients taking anti-platelet medications is controversial. OBJECTIVE To assess the effect of anti-platelet therapy on perioperative blood loss in patients undergoing appendectomy either(More)
BACKGROUND Cancer is a leading cause of mortality worldwide. Screening is a key strategy for reducing cancer morbidity and mortality. METHODS We aimed to describe the experience of an integrated cancer prevention center in screening an asymptomatic population for the presence of neoplasia. One-thousand consecutive asymptomatic, apparently healthy adults,(More)
BACKGROUND Cancer is a leading cause of mortality worldwide. The most effective way to combat cancer is by prevention and early detection. OBJECTIVES To evaluate the outcome of screening an asymptomatic population for the presence of benign and neoplastic lesions. METHODS Routine screening tests for prevention and/or early detection of 11 common cancers(More)
BACKGROUND Allogeneic perioperative blood transfusion (PBT) has been associated with higher rates of postoperative complications in patients undergoing colorectal surgery and increased tumor recurrence in cancer patients. Our aim is to evaluate possible predictive factors for PBT, specifically, in patients undergoing laparoscopic colorectal surgery, in(More)
INTRODUCTION The accumulated data in recent years on the safety of laparoscopy in colorectal cancer patients encourage more surgeons to use this approach for different colorectal pathologies. However, laparoscopic colorectal surgery consists of different heterogeneous complex procedures that necessitate extensive experience and laparoscopic surgical skills(More)
Reflectance spectroscopy can be used to quantitate subtle differences in color. We applied a portable reflectance spectrometer to determine its utility in the evaluation of pulsed dye laser treatment of port wine stains (PWS) and in prediction of clinical outcome, in a prospective study. Forty-eight patients with PWS underwent one to nine pulsed dye laser(More)
Epiphrenic diverticulum of the esophagus is an uncommon finding. Small diverticula are usually asymptomatic in nature. Large diverticula may present with dysphagia, chest or upper abdominal discomfort, vomiting, irritating cough or halitosis. There are a few different surgical approaches to epiphrenic diverticulum resection. It can be performed with an(More)
