A very low local recurrence rate of 3%-6% (associated with improved 5 year survival) is possible when proper oncological surgery is performed of mid and distal rectal adenocarcinoma. Restoration of bowel continuity is possible in most cases, without compromise of cancer clearance. Re-anastomosis can be performed with stapled, transabdominal hand-sewn or coloanal pull-through techniques. However...
BACKGROUND Gastrointestinal anastomosis remains associated with a considerable burden of morbidity and, in some cases, mortality. Functional end-to-end anastomosis, whilst extremely efficient, is vulnerable to increased intestinal pressure in the immediate postoperative period, which may predispose to development of anastomotic leakage or bleeding. Therefore, there is a requirement for new tech...
In advanced cancers of hepatobiliary and pancreatic lesions, major vascular resection and reconstruction are necessary to accomplish curative resection. Stenosis of vascular anastomosis is a concern in case of portal or superior mesenteric venous anastomosis with different vascular calibers. We attempted to apply parachute anastomosis in such a situation, which has often been used in the field ...
BACKGROUND Transperitoneal robot-assisted laparoscopic prostatectomy (RALP) urethrovesical anastomosis is a critical step. Although the prevalence of urine leaks ranges from 4.5% to 7.5% at high-volume RALP centers, urine leaks prolong catheterization and may lead to ileus, peritonitis, and require intervention. Barbed polyglyconate sutures maintain running suture line tension and may be advant...
INTRODUCTION The aim of this study was to evaluate the plasma levels of hypoxanthine (HX) and xanthine in the renal vein blood samples for prediction of delayed graft function (DGF). MATERIALS AND METHODS Two blood samples were taken from 47 kidney recipients, intraoperatively. The first sample was obtained from a peripheral vein before vascular anastomosis and the second from the allograft r...

Failure of intestinal anastomosis is a major complication following abdominal surgery. Biological materials have been introduced as reinforcement of abdominal wall hernia in contaminated setting. An innovative application of biological patch is its use as reinforcement of gastrointestinal anastomosis. The aim of study was to verify whether the bovine pericardium patch improves the healing of an...
Markowitz’s portfolio selection problem chooses weights for stocks in a portfolio based on a covariance matrix of stock returns. Our study proposes to reduce noise in the estimated covariance matrix using a Tikhonov filter function. In addition, we propose a new strategy to resolve the rank deficiency of the covariance matrix, and a method to choose a Tikhonov parameter which determines a filte...
