A 56-year-old woman with a history of sciatica, who had been taking nonsteroidal anti-inflammatory drugs (NSAIDs) for one year complained of abdominal fullness, rectal bleeding, and decreased stool caliber for the past six months. An endoscope could not be extended beyond a stenosed region within the descending colon. This narrowed area appeared suggestive of a diaphragm-like stricture and was ...

The purpose of this investigation was to evaluate the efficacy and safety of implanting expandable intravascular stents in pulmonary arteries and systemic veins. Twenty-seven balloonexpandable grafts were placed in 13 mongrel dogs under anesthesia. A long sheath was introduced over a wire and catheter or dilator into the pulmonary artery or target vein. A collapsed stainless steel expandable me...

Malignant strictures of the proximal to mid small bowel have been successfully managed by deploying enteral stents with the use of an overtube [1,2]. In case reports and published series, stents have been deployed only to the ligament of Treitz and rarely into the proximal jejunum [3,4]. We present here the case of a benign stricture in the distal jejunum managed by deploying a partially covere...

We report a case with a large bladder diverticulum caused by the bladder outlet obstruction, which was successfully treated with laparoscopic extraperitoneal diverticulectomy. The patient was a 71-year-old man, who had had dysuria, micturition pain and cloudy urine. We found the patient to have benign prostatic hyperplasia and a large diverticulum of the bladder. We removed the diverticulum by ...

transluminal balloon valvuloplasty is an alternative to surgical valvotomy for congenital pulmonary valve stenosis. the aim of this study was to evaluate the long term results (to 13.5 years) of balloon pulmonary valvuloplasty. from june 1998 to january 2012, percutaneous balloon pulmonary valvuloplasty for congenital pulmonary valve stenosis was performed in 98 patients (50 males, 48 females, ...

background : approach to the small intestine has been difficult even with newer methods. double-balloon enteroscopy (dbe) has been created for diagnostic and therapeutic interventions in diseases of the small intestine. small intestinal diseases have different etiologies in each country. the dbe has been introduced in recent years in iran. our aim was to study the indications and results of dbe...

introduction: insome cases, assist devices are required to ensure an adequate cardiac output after cardiac surgery. intra-aortic balloon pump (iabp) is the most commonly used cardiac assist device, which provides first-line support for patients with heart failure. the aim of this study was to determine factors affecting the mortality rate of patients receiving iabp. materials & methods:  in thi...

OBJECTIVES To evaluate the technique of laparoscopic kidney transplant and demonstrate the feasibility of this procedure by an extraperitoneal approach. MATERIALS AND METHODS The procedure was performed on 2 human cadavers. Retroperitoneal endoscopic left nephrectomy was performed. An extraperitoneal space was established by inflation of a balloon dilator. The external iliac artery and vein w...

Needle cricothyrotomy is a safe, relatively easy procedure and has been described to enable pulmonary ventilation for patients in both elective and emergency situations. Conventional IV cannulae are short, thin-walled, and easily kinked and, therefore, do not provide a secure system to jet oxygen into the trachea. The vessel dilators of most 7-9 French introducer kits are firm, pliable, resist ...
