To assess the value of pneumatic dilatation of the cardia, 63 patients with achalasia have undergone a total of 107 Rider-Moeller dilatations over the last six years. There was a marked improvement in swallowing immediately after dilatation in all but two patients, there were no deaths attributable to the procedure and serious complications were rare (1.6% of patients). The first 50 cases have ...

AIM To evaluate the use of anorectal manometry to select patients for controlled anal dilatation. METHODOLOGY A prospective study was performed using anorectal manometry on all patients with chronic anal fissure who did not have a good response to conservative treatment. Those with increased anal resting pressure were treated with controlled anal dilatation using a two valved anuscope. A seco...

BACKGROUND The treatment of urethral stricture in female patients is through dilatation of the urethra by tubes of increasing diameter. There are two main methods: intermittent dilatation and on demand dilatation. OBJECTIVES The main aim of this study was to compare the results of these two methods, and to determine the best one. PATIENTS AND METHODS In this clinical trial study, we reviewe...

BACKGROUND Bicuspid aortic valve (BAV) is related to aortic dilatation, but patterns/rates are conflicting with no comparison among aneurysms of different aetiology. We sought to define ascending aorta dilatation patterns/progression rates in BAV versus other aortopathies (Marfan syndrome (MFS), degenerative aortopathy (DA)). DESIGN AND SETTING Retrospective, observational study. Aortic dilat...

OBJECTIVE To compare the results of balloon dilatation (BD) vs. telescopic metal dilators (TMDs) in establishing the tract for percutaneous nephrolithotomy (PCNL) in patients with calyceal stones or staghorn stones, but with no hydronephrosis. PATIENTS AND METHODS Data from selected patients over 4 years were recorded retrospectively. Patients with complex staghorn stones, an undilated target...

Objective: The cows that don’t have access to sufficient energy in their ration can get sickness. Milk production has a high priority in metabolism of dairy cows so lactating cows are more prone to get sick This can ruin all the benefits of higher milk yield because of the higher prevalence of the disorders. Methods: Data for this research had gathered from a herd with 1600 Holstein cattle in E...

Balloon dilatation angioplasty was successfully performed in five patients (ages 18 months to 17 years) with discrete aortic coarctation. The catheter size was No. 8F or 9F. Selection of balloon diameter was based on angiographic measurements of the aorta determined proximal and distal to the coarctation site. A 10 sec inflation-deflation cycle at 6 to 8 atmospheres (90 to 120 psi) was performe...

OBJECTIVES (a) To assess the echocardiographic incidence of restenosis after successful balloon dilatation of the mitral valve at a mid-term follow up of one year among a population of predominantly United Kingdom patients. (b) To identify any factors, assessed before or during dilatation, which may predict the development of restenosis. DESIGN Successful dilatation of the mitral valve was de...

One thousand consecutive labours in primigravid patients were evaluated to show the value of the combined use of a cervical dilatation graph and a policy of active management. Intervention was required at a significantly higher rate in patients with abnormal cervical dilatation patterns. Significantly more Caesarean sections were performed in patients with abnormal cervical dilatation pattern. ...

Cervical dilatation is a key event for successful vaginal delivery of young ones that occur just before parturition. Failure of cervical dilatation due to alterations in cervical ripening mechanism or insufficient uterine contraction poses problems in delivery of fetus. Cervical ripening is a multifactorial process which is an outcome of hormonal regulation, inflammatory process and enzymatic b...
