Postoperative Gastric Perforation in a Newborn with Duodenal Atresia.

Gastric perforation (GP) in neonates is a rare entity with high mortality. Although the etiology is not completely understood, it mostly occurs in premature neonates on assisted ventilation. Combination of duodenal atresia and gastric perforation is very rare.

Resistance index in mural arteries of thickened bowel wall: predictive value for Crohn disease activity assessment in pediatric patients.

Objective: To define reliable Doppler parameters in mural arteries of affected bowel loops for quantitative assessment of Crohn disease (CD) activity in pediatric population and compare Doppler parameters with Pediatric Crohn Disease Activity Index (PCDAI).

Patients And Methods: Thirty-four pediatric patients (7 with inactive, 27 with active disease of different severity; 13 male and 21 female; mean age 13; range 7-18) with CD were prospectively evaluated by Doppler ultrasound (DUS) of affected bowel segments. Using semiquantitative color and power Doppler assessment of vascularization of thickened bowel wall and mesentery, patients were divided in four grades.

[High resolution B-mode and Doppler ultrasound in diagnostic evaluation of Crohn's disease].

Evaluation of extension and complications as well as assessment of Crohn's disease activity, include different diagnostic methods, of which many utilize ionizing radiation. In our routine work, high resolution B-mode and Doppler ultrasound with measurements of bowel wall thickness and hyperemia, as well as calculation of resistance index of mural arteries and visualisation of extramural changes, represent valuable diagnostic tools in screening, assessment of disease activity, and follow up of the patients with Crohn's disease. Therefore, we reduce the use of ionization radiation in diagnostic workup, which is particulary important considering the fact that Crohn's disease predominantly affects young patients.

Assessment of Crohn's disease activity by doppler ultrasound of superior mesenteric artery and mural arteries in thickened bowel wall: cross-sectional study.

Aim: To define sensitive and reliable Doppler parameters for measurements in the superior mesenteric artery and mural arteries of affected bowel loops used in the assessment of Crohn disease activity.

Methods: We performed cross-sectional study at a tertiary care setting in Zagreb, Croatia, between January 2001 and March 2005. We measured arterial flow in the superior mesenteric artery and affected bowel wall in 138 patients with Crohn disease (74 with active, 64 with inactive disease) and 67 healthy volunteers.

[Primary sclerosing cholangitis: case report of a young patient with an atypical diagnostic process in complications of the disease].

The primary sclerotic colangitis is the chronic disease of the liver which in its finish very often requires the liver transplantation. The disease gets diagnosed mainly in males of middle age and is often joined with the inflammation disease of the intestines. The course of the disease not rarely is complicated by the stenosis of the liver ducts or by the occurrence of the concrements.
