AIM Micro-vascular anastomosis is a difficult art. It can be learnt and perfected only by practice using vessels of small animals in the laboratory. The purpose of the study was to practice various anastomotic techniques using rat femoral vessels and study the patency rates. MATERIAL AND METHODS Sixty-four Sprague-Dawley rats were used in the study. The following procedures were conducted on ...

The fungus Pseudocercospora griseola is the causal agent of angular leaf spot, a common bean (Phaseolus vulgaris L.) disease. The successful development of angular leaf spot-resistant cultivars depends on understanding the levels of variability in pathogen populations. P. griseola shows great pathogenic and genetic variation using inoculation on differential bean cultivars and molecular markers...

The proximal anastomosis of the apicoarotic bypass is technically demanding. We describe our novel surgical technique to reinforce the proximal anastomosis of the apicoaortic bypass. After moving circular muscle of the left ventricle (LV) under ventricular fibrillation, an inverted tube graft is inserted into LV through the opening of the apex. Then, end-to-end anastomosis is made with horizont...

OBJECTIVE Mechanical suture (stapler) has been in use for bowel anastomosis since the second half of the 20th century, however, it became popular since it was used widely by the United States of America in the late 1960. Since it is more expensive than the conventional method, a local experimental assessment was introduced to compare stapler with conventional methods. METHODS Eighteen local d...

Here we report a case of moyamoya disease in which cortical veins reddened after superficial temporal artery (STA) to middle cerebral artery (MCA) anastomosis, following postoperative hyperperfusion. A 37-year-old man with moyamoya disease suffered cerebral infarction in his right hemisphere. Single photon emission computed tomography (SPECT) showed impaired cerebral blood flow (CBF) in both ce...

PURPOSE Ileal pouch-anal anastomosis has come to represent the procedure of choice for patients requiring surgery for mucosal ulcerative colitis. In contrast, a proven diagnosis of Crohn's disease is generally held to preclude ileal pouch-anal anastomosis. However, patients with ileal pouch-anal anastomosis for apparent mucosal ulcerative colitis who are subsequently found to have Crohn's disea...

Background: Total colectomy is used in children with total colonic aganglionosis, Ulcerative colitis (UC) and familial adenomatous polyposis (FAP). The purpose of this study was to maintain ileocecal valve and rectal-sparing surgery for the prevention of fecal incontinence in these children. Methods: From1990 to 2011, 14 children with diagnosis of UC, FAP and Hirschsprung’s disease were operat...

BACKGROUND  Compared with hand-sewn anastomoses, microvascular anastomotic coupling devices (MACDs) provide equivalent flap survival and reduced operative time. To date, an economic analysis of MACDs has not been reported. The objective of this study was to evaluate the economics of a venous anastomosis performed using a coupling device compared with a hand-sewn anastomosis. METHODS  Economic...

In the retroperitoneal space the gonadal veins form a collateral circulation that has a great clinical impact on sclerotherapy or surgical ligation of varicoceles. The aim of this study was to examine the communications of the gonadal veins (according to classification, frequency of appearance, gender and syntopic differences) in human foetuses of both sexes (71 males and 59 females) aged 4--6 ...
