OBJECTIVE To evaluate the immediate results of mechanical aorto-saphenous anastomosis compared with conventional anastomosis. METHOD We evaluated 12 patients. The mean age ranged from 62.33 +/- 7.30 years. Of 12 patients submitted to surgery without extracorporeal circulation, 10 (83.3%) patients were male. Thirty-three proximal anastomoses were evaluated, 21 of them being performed through t...

Introduction An 80-year-old man with a previous history of recurrent urinary tract infections presented with intermittent, painful and whole stream gross haematuria for 2 months. Physical examination was unrevealing. The result of urine cytology was negative for malignancy. Intravenous pyelography (IVP) revealed left hydronephrosis with obstruction at left ureterovesical junction, radiolucent f...

Vesicoureteral reflux (VUR) is simply described as incompetence of the unidirectional valve at the ureterovesical junction (UVJ), leading to backflow of urine to the kidney. Today, it is clear that VUR is not only related to the UVJ function but also to a combination of processes including immunity, bladder and pelvic floor function, dysfunctional voiding, and constipation. Although our surgica...

BACKGROUND AND AIMS Colorectal cancer is one of the most frequent digestive malignancies, being the third cause of death by cancer, despite early diagnosis and therapeutic progress made over the past years. Standard treatment in these patients is to preserve the anal sphincter with restoration of intestinal function by mechanical colorectal anastomosis or coloanal anastomosis, and to maintain g...

The only curative treatment for familial adenomatous polyposis (FAP) is prophylactic surgery and the two most popular options are total colectomy with ileorectal anastomosis and restorative proctocolectomy with ileal pouch-anal anastomosis. Today, ileal pouch-anal anastomosis has gained wider acceptance as a safer procedure, but ileorectal anastomosis still remains an option, especially for you...

Training of microvascular anastomosis techniques comprise the major part of surgical skills, necessary for revascularization surgeries. Training can be performed in several stages based on the experience of trainees. This should mainly start with various models of artificial materials that simulate tissues. In the next stage, trainee should practice microsurgical skill on a non-living tissue mo...

abstract vascular injury presents a great challenge to the emergency resident because these injuries require urgent intervention to prevent loss of life or limb. sometimes serious vascular injury presents with only subtle or occult signs or symptoms. the patient may present weeks or months after initial injury with symptoms of vascular insufficiency, embolization, pseudoaneurysm, arteriovenous ...

abstract   background: iatrogenic airway injury after endotracheal intubation and tracheotomy remains a serious clinical problem. in this study we reviewed post-intubation and traumatic tracheal stenosis in 47 patients with a special attention to the cause, hense surgical treatment of the stenosis was performed and the results compared with the literatures.   methods: since february 1995 throug...

Recent developments in laparoscopic gastrectomy have led to the introduction of various methods of stapled anastomosis. We have also introduced stapled anastomosis to reconstruction of the digestive tract with the aim of performing safe and quick anastomosis and enabling an early return to oral feeding. Reconstruction of the digestive tract following pancreaticoduodenectomy in our institution i...

Ureteric stones are a common cause of obstruction of the urinary tract, usually presenting with characteristic signs and symptoms, such as acute ureteric colic and hematuria. Occasionally, stones may present with non-specific symptoms such as low back pain and remain unidentified, leading to stone growth, chronic ureteric obstruction and complications such as hydronephrosis and renal damage. He...
