The use of a short double-balloon endoscope facilitates the endoscopic removal of bile duct stones in patients with surgically altered anatomy [1,2]. However, the narrow and long working channel of the double-balloon endoscope occasionally makes the procedure difficult and timeconsuming. Herein, we present the case of a patient with a history of hepaticojejunostomy in whom large bile duct stone...

balloon dilatation of stricture is one of the new treatment methods among patients with gastric outlet obstruction (goo). however, the prevalence and underlying etiologies of goo in various populations are different. the goal of the present study was to determine the effectiveness of endoscopic balloon dilatation and factors that would affect its success rate patients with benign etiology for g...

Experiments were undertaken to determine the influence of increasing left atrial pressure on renal function in the nonhuman primate. Significant elevations of left atrial pressure, produced by using an intra-atrial balloon, had no effect on salt or water excretion, renal plasma flow, or glomerular filtration rate. There were no significant changes in heart rate or blood pressure. We conclude th...

Background: The aim of this study is to evaluate whether the location of the balloon placement into either the cervical canal or uterine cavity during sonohysterography can affect the intensity of pain. Materials and Methods: A total of 300 infertile women undergoing sonohysterography were randomized to intracervical or intrauterine balloon placement. The examination was scheduled in the early ...

Balloon water vapour in situ and remote measurements in the tropical upper troposphere and lower stratosphere (UTLS) obtained during the HIBISCUS campaign around 20 S in Brazil in February–March 2004 using a tunable diode laser (μSDLA), a surface acoustic wave (SAW) and a Vis-NIR solar occultation spectrometer (SAOZ) on a long duration balloon, have been used for evaluating the performances of ...

OBJECTIVES To determine the action of the Foley catheter in the posterior nasal cavity in relation to balloon volume, and to deduce its implications in the treatment of posterior epistaxis. DESIGN Human cadaveric study. MATERIALS Twenty nasal fossae of 10 adult cadavers. INTERVENTIONS A Foley catheter (size 14) was inserted into the nasopharynx via each nostril. The catheter balloon was i...

Our group is currently developing an intravenous respiratory assist device that uses a centrally located pulsatile balloon within a hollow fiber bundle to enhance gas exchange rate via active mixing mechanism. We tested the hypothesis that the non-symmetric inflation and deflation of the balloon lead to both nonuniform balloon-generated secondary flow and nonuniform gas exchange rate in the fib...
