Gallbladder varices: diagnosis in children with portal hypertension on duplex sonography.

We established the prevalence of gallbladder varices (GBVs) as seen on duplex sonogram of children with portal hypertension. Fifty-five consecutive children with portal hypertension underwent duplex sonographic examination by an experienced sonologist who was blinded to clinical presentation. Forty children had extrahepatic portovenous obstruction (EHPVO), 12 had cirrhosis, and three had noncirrhotic portal hypertension. GBVs were seen on sonography in 10 of 40 children with EHPVO (25%), two of 12 children with cirrhosis (16.6%), and no children with noncirrhotic portal hypertension. Sonographic findings of GBVs were confirmed on duplex sonographic imaging. Among patients with EHPVO, GBVs did not correlate with size of esophageal varices, number of sessions of sclerotherapy, presence or absence of gastric varices, portal gastropathy, or splenorenal shunt placement. In cirrhotic patients, GBVs did not correlate with Child Pugh grade. Children with EHPVO have a higher incidence of developing GBVs. The clinical significance of GBVs is their propensity to bleed during biliary surgery; thus, the operating surgeon should be made aware of them.

Achalasia cardia dilatation using polyethylene balloon (Rigiflex) dilators.

OBJECTIVE: Results of 20 dilatation sessions in 15 patients with achalasia cardia were assessed to determine the safety and efficacy of polyethylene balloon achalasia dilators (Rigiflex). METHODS: All patients underwent an initial dilatation by inflating a 30 mm balloon to 9 psi for one minute. Need for subsequent dilatations was assessed on symptom assessment; 35 mm balloon was used for repeat procedure. RESULTS: Overall success rate was 93.3%. The 30 mm balloon achieved a satisfactory result in 73.3% and the 35 mm balloon in 75% of the remainder. Only one patient needed surgery. No short-term complications were observed. The only late complication encountered over an average follow-up period of 16.2 months was gastroesophageal reflux in two patients. CONCLUSIONS: Dilatation using Rigiflex dilators is a safe, effective and simple procedure for treating patients with achalasia.

Asymptomatic spinal tuberculosis presenting as esophageal stricture.

Esophageal tuberculosis is rare and is usually due to secondary extension from contiguous structures. We report a patient who presented with dysphagia and was found to have esophageal stricture. Endoscopic biopsy was not suggestive of malignancy or tuberculosis. CT scan of the thorax revealed involvement of the fourth thoracic vertebra with paratracheal lymphadenopathy. The patient responded to anti-tubercular therapy.
