BACKGROUND/AIM Balloon dilatation is a standard approach to the initial achalasia treatment. Modified dilatation is also applied to rise efficacy and to lower complications. METHODS A total of 57 patients were analysed within a median follow-up of 8.2 years. No premedication was used, dilatation was performed up to the pain treshold, while introduction and positioning of a dilatator was done ...

1. In 13 patients with hypertension and renal artery stenosis the stenosis was dilated by an intra-arterial balloon catheter under local anaesthesia. 2. In all but one instance arteriography after the dilatation showed considerable widening of the stenosed area. 3. Six patients had a temporary increase of serum creatinine that lasted only a few days. 4. In seven patients, who had a prolonged tr...

BACKGROUND The occurrence of anastomotic stricture at the level of the rectum gives rise to three broad therapeutic options, namely major pelvic and abdominal revisional surgery, faecal diversion (stoma), or local revision by transanal approaches (including endoscopic and fluoroscopic). This article updates the current evidence and focuses on the results of the balloon dilatation technique. M...

Operative balloon dilatation of the aortic valve was performed in seven neonates with critical stenosis of the aortic valve. The procedure was followed by the development of severe aortic regurgitation in four patients. Necropsy was performed in three and revealed partial detachment of the right coronary cusp of the aortic valve. Damage to the valve leaflet caused by balloon dilatation was prob...

Title: Endoscopic balloon dilatation for benign hepaticojejunostomy anastomotic stricture using short double-balloon enteroscopy in patients with a prior Whipple's procedure: a retrospective study Authors: Sho Mizukawa ([email protected]) Koichiro Tsutsumi ([email protected]) Hironari Kato ([email protected]) Shinichiro Muro ([email protected]) Yutaka Akimoto ([email protected])...

PURPOSE To clarify what is safe use of balloons in interventional neuroradiologic procedures. METHODS Critical parameter values of balloon inflation and cerebral artery dilatation and rupture were determined. Dimensions and internal pressure were measured for a variety of latex and silicone balloons during inflation in both unconstrained and constrained environments including glass tubes, cad...

PURPOSE To evaluate the efficacy of Palmaz balloon-expandable metallic stents for the maintenance of luminal patency in the treatment of recurrent nasolacrimal duct, obstructions after failed transluminal balloon dilatation. METHODS Metallic stents were implanted in the nasolacrimal duct of four patients with recurrent epiphora. All the patients had already undergone transluminal balloon dila...

Subcostal echocardiography of the left ventricle was continuously recorded during balloon dilatation of the aortic valve in ten consecutive elderly patients. Left ventricular wall motion decreased gradually during a minute of maintained complete balloon inflation. Blind analysis of M mode echocardiograms showed a significant reduction in fractional shortening. Deflation of the balloon resulted ...

Pressure in oesophageal varices has been measured either by using an invasive puncture technique, or a non-invasive pneumatic pressure sensor. Experience with these techniques and their limitations prompted a new way of measuring pressure in oesophageal varices. This was done by observing through a transparent plastic balloon fixed to the tip of a gastroscope the pressure equilibrium between th...
