Diagnostic potential of T1ρ and T2 relaxations in assessing the severity of liver fibrosis and necro-inflammation.

Purpose: To investigate the utility of T1ρ and T2 relaxations for assessing the severity of liver fibrosis (F stage) and necro-inflammation (A stage) in patients with chronic liver disease (CLD).

Materials And Methods: We calculated T1ρ and T2 relaxations of the liver parenchyma in 82 patients who underwent liver surgery. F and A stages of enrolled patients were assessed by referring to surgically resected specimens.

A new method of transanal catheter fixation for neonates with long segment-type Hirschsprung's disease.

We managed long-segment aganglionosis in two neonates by performing colonic irrigation through an indwelling transanal catheter for 65 and 30 days, respectively, until a laparoscopy-assisted primary pull-through operation could be performed. The catheter was fixed by tying it to the tubes, criss-crossed at the anus, and securing the opposite ends of the tubes away from the diaper. This form of management with our devised method of transanal catheter fixation and simple frequent tube washouts improved the preoperative quality of life of both the babies and their parents remarkably.
