Barium study associated with water siphon test in gastroesophageal reflux disease and its complications.
2007
PURPOSE: The aim of this study was to evaluate the role of digital cineradiography associated with the water siphon test (WST) in the diagnosis of gastroesophageal reflux and to compare the results with oesophageal motility study, pH monitoring and endoscopy associated with biopsy and histology. MATERIALS AND METHODS: One hundred and sixty consecutive patients underwent digital cineradiography with WST, motility study, pH monitoring and endoscopy with biopsy. The presence of gastroesophageal reflux, oesophagitis, Barrett''s oesophagus and intestinal metaplasia was evaluated. RESULTS: WST vs. pH monitoring showed sensitivity of 71%, specificity of 31%, positive predictive value (PPV) of 53% …
Rectal perforation during defecography: extraluminal barium impaction removed by TEM (Transanal Endoscopic Microsurgery).
2016
Defecography is the standard diagnostic technique for the diagnosis of functional disorders of the posterior pelvic compartment. However it has some limits as radiation exposure, low-contrast resolution, some degrees of embarrassment and discomfort for the patients. Furthermore it often fails to directly visualize the changes that affect the pararectal space. Here we present a never described case of rectal perforation after defecography with barium impaction removed by TEM (Transanal Endoscopic Microsurgery).We present a case of a 50 years old woman with extraluminal barium impaction due to perforation occurred during defecography. Both pelvic MR and endoanal ultrasound confirmed the prese…
Verlaufskontrolle des Morbus Crohn: Kann die Hydro-MRT die fraktionierte Magen-Darm-Passage ersetzen?
1997
PURPOSE: To compare the value of hydro-MRI with follow-through examinations in the follow-up of Crohn's disease. METHOD: 22 patients known to be suffering from Crohn's disease were examined via 1.5 T-MR system; an oral contrast examination using 1000 ml of a 2.5% mannitol solution was performed in all patients. T2-weighted TSE sequences and T1-weighted SE sequences were performed before and after the intravenous injection of Gd-DTPA. To reduce movement artifacts caused by peristalsis of the gut, intravenous injection of 40 mg Buscopan was given. The findings of hydro-MRI were compared with the follow-through examinations. RESULTS: In the upper gastrointestinal tract, the follow-through exam…
Inhibition of the precipitation of barium salts in sodium dodecyl sulfate/0.1 M HCl/n-pentanol microemulsions and liquid crystals
1989
Abstract The phase ternary diagram of the sodium dodecyl sulfate (SDS)/0.1 M HCl/n-pentanol system is studied. Three monophase regions were observed: water rich and n-pentanol rich microemulsions, and a liquid crystal. These media have a strong ability to control the rate of crystal growth of barium sulfate and barium dodecyl sulfate, the precipitation being totally inhibited in the liquid crystal region.
Accuracy of the water-siphon test associated to barium study in a high prevalence gastro-oesophageal reflux disease population: a novel statistical a…
2010
Abstract RATIONALE, AIMS AND OBJECTIVES: Gastro-oesophageal reflux disease (GORD) is 'a condition which develops when the reflux of gastric content causes troublesome symptoms or complications'. Instrumental diagnostic tests generally used for GORD are 24-hour pH-metry and upper gastrointestinal (GI) endoscopy but barium study associated with provocative manoeuvres such as the water-siphon test (WST), has also been used for GORD. The aim of this paper was to estimate the accuracy of several tests in patients with GORD in a tertiary care setting, focusing on WST, which is rapid and non-invasive, simple to perform and well-tolerated by patients. METHOD: A total of 172 consecutive patients, sy…

Small-Bowel Diagnosis in Patients with Familial Adenomatous Polyposis: Comparison of Push Enteroscopy, Capsule Endoscopy, Ileoscopy, and Enteroclysis
2009
BACKGROUND: Conventional upper endoscopy (EGD), EGD with side-view endoscope and ileoscopy are established procedures for endoscopic evaluation of patients with familial adenomatous polyposis (FAP). However, we still have little data on the frequency and relevance of adenomas in those parts of the small bowel which are not accessible to EGD and ileoscopy. Adenomas distal to the duodenum are found more often in FAP patients with known duodenal adenomas. The question is, whether these patients can benefit from additional endoscopic and/or radiographic examinations. METHODS: Between July 2001 and August 2006 we performed comparative small bowel studies with push enteroscopy (PE), capsule endos…
El uso precoz de la tomografía computarizada en el manejo de la diverticulitis aguda
2007
Objetivo: valorar el uso precoz de la tomografía computarizada (TC) para el diagnóstico, estadificación y manejo de la diverticulitis aguda. Material y métodos: realizamos un estudio prospectivo de 102 pacientes con el diagnóstico clínico de diverticulitis aguda de colon izquierdo. La diverticulitis aguda fue inicialmente dividida en tres estadios. Los pacientes fueron reestadiados en los estadios I, IIa, IIb y III de acuerdo a los hallazgos encontrados en la TC. El diagnóstico se confirmó después intraoperatoriamente, por colonoscopia o estudio con bario. Resultados: fueron incluidos 102 pacientes (52 mujeres y 50 hombres) con una edad media de 59,4 (DS ± 14,96). En 84 (82,35%) paci…
