BACKGROUND Due to differences in surgical operations between free-hand and robot-assisted vessel anastomosis, there exist new challenges in applying the manipulation criteria of free-hand surgery to robot-assisted surgery in order to guarantee successful completion of the surgical procedure. METHODS A mathematical model is established to optimize the process variables in vessel anastomosis. T...

Most surgeons perform coronary bypass surgery with the aid of cardiopulmonary bypass, which inflicts a massive systemic inflammatory response to the body leading to adverse clinical outcome. In an attempt to make CABG less invasive, interest have been diverted to the off pump technique.The current review attempts to bring an insight onto the last ten years knowledge on the off-pump impact in en...

Context: To measure central macular thickness (CMT) in diabetic patients after instilling intracameral dexamethasone at the end of cataract surgery and compare this measure with control group. Design: Prospective case-control study. Participants: 100 eyes of 100 diabetic patients undergoing cataract extraction. Methods: 50 eyes received intracameral dexamethasone 0.4mg/0.1ml at the end of surge...

background: erythropoietin (epo) is known as a regulating hormone for the production of red blood cells, called erythropoiesis. some studies have shown that epo exerts some non-hematopoietic protective effects on ischemia-reperfusion injuries in myocytes. using echocardiography, we evaluated the effect of epo infusion on reducing ischemia-reperfusion injuries and improvement of the cardiac func...

AIM To compare the success and complication rates, duration of surgeries and clinical comfort after endoscopic dacryocystorhinostomy (END-DCR) or external dacryocystorhinostomy (EXT-DCR). METHODS Fifty patients who underwent EXT- or END-DCR between January 2010-2012 were involved in the study. A questionnaire was applied to patients preoperatively, and postoperatively. Subjective success was ...
