Nearly all surgical disciplines have developed endoscopic operations over the last 2 decades that have become the standard of care. In cardiac surgery and specifically for coronary artery bypass grafting (CABG), the adoption of minimally invasive techniques was challenging for the following reasons: First, most procedures are already complex, and endoscopic approaches further increase the degre...

The classic Dieulafoy lesion is a minute gastric mucosal defect which bleeds massively from an exposed artery. The typical endoscopic appearance of this lesion is a single, round mucosal defect with an artery protruding from its base in the absence of surrounding ulceration. We encountered an 89-year-old man who developed sudden massive fresh rectal bleeding. The source of hemorrhage was found ...

PURPOSE To describe a minimally invasive technique for conjunctivodacryocystorhinostomy with the Jones tube. This technique creates a direct communication between the conjunctiva and the middle meatus with the use of a 14-gauge angiocatheter. The glass tube is inserted under endoscopic or direct visualization. METHODS A retrospective review of consecutive patients who underwent the minimally ...

Inverted papilloma is a common, benign sinonasal tumor with known high rate of recurrence. To prevent recurrences, complete excision inverted essential. In excision, especially, identifying the attachment site and managing meticulously important. this study, we introduce two surgical methods for that can reduce recurrence rate: prelacrimal approach ‘origin cauterization drilling (painting washi...

OBJECTIVE Aneurysms of the vertebral artery are rare, comprising less than 5% of all aneurysms. They can present with subarachnoid hemorrhage, medullary compression, and cranial neuropathies. In consideration of their surrounding regional anatomy, they present a formidable surgical challenge to the neurosurgeon using traditional techniques. Recent advances in endoscopic transnasal surgery have ...

Endoscopic treatment for non-variceal upper gastrointestinal bleeding has evolved over decades. Injection with diluted epinephrine is considered as a less than adequate treatment, and the current standard therapy should include second modality if epinephrine injection is used initially. Definitive hemostasis rate following mono-therapy with either thermo-coagulation or hemo-clipping compares fa...

The benefits of minimally invasive cardiac surgery are manifold, including less trauma to tissue and consequently less pain, shorter hospital stay and faster recovery. Nevertheless problems remain in the complex operative procedure with long instruments and small aditus to the operating field. In coronary artery bypass graft operations the exact identification of the target artery on the heart ...
