(21) In our study, most of our cases were performed with balloon dilators
without any failure.
has many advantages like one step dilation of the tract and also helps in renal displacement prevention throughout tract creation.
*Regimen 1: A balloon dilator
was initially used to expand the stenosis.
Nephrostomy tract dilation using a balloon dilator
in percutaneous renal surgery: Experience with 95 cases and comparison with the fascial dilator system.
There are several dilatation methods available, including Amplatz polyurethane serial dilators (ASDs), metallic telescopic dilators as described by Alken, and balloon dilators
. Amplatz-assisted serial dilators have currently been shown to be superior to balloon dilators
in a large multicentre international study.
The failures resulted from organ damage (2) and inability to insert over-the-wire balloon dilator
into gastric puncture (3).
9 November 2011 - Boston Scientific Corporation (NYSE:BSX) has received CE Mark for the use of its Wireguided Balloon Dilator
for endoscopic dilation of the Sphincter of Oddi following sphincterotomy.
This is dilated using a balloon dilator
. Flexible cystoscopy and flexible urethroscopy is performed and a guidewire is placed antegrade.
The dilatations were carried out using either a Rigiflex (Microvasive) achalasia balloon dilator
(diameter 35 mm) or a Witzel endoscopic pneumatic dilator.
For patients in the EPLBD alone group, a large-size balloon dilator
[greater than or equal to] 12 mm (CRE wire-guided dilator, Boston Scientific, MA, USA) was passed over a prepositioned guidewire, positioning the deflated balloon across the main duodenal papilla.
An 18x20-mm esophageal stent (Cook Evolution fully covered stent) was advanced to the stomach with the help of previously placed guide wire under fluoroscopic visualization (Figure 1), 18-20-mm balloon dilator
was inserted through the stent, and dilation was performed.
Three types of dilators are available: Amplatz fascial dilator, telescopic metal dilator, and balloon dilator
. Balloon dilators
are limited in use because of their high costs, although they are safe and widely accepted.
