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 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)
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 grades. Data of(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)
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 order to(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)
BACKGROUND Laparoscopic surgery has been associated with a perioperative decrease in renal function. As a result, an open approach may be preferred in patients with impaired renal function when prolonged laparoscopic procedures are anticipated. The aim of this study was to examine changes in renal function following colorectal operations and compare between(More)
BACKGROUND Weight loss in morbidly obese patients is associated with changes in thyroid function. Studies have demonstrated equivalent changes following bariatric surgery. Changes in thyroid function were reported following laparoscopic Roux-en-Y gastric bypass (LRYGB), biliopancreatic diversion (BPD), and laparoscopic adjustable gastric banding (LAGB). No(More)
