Increased Prevalence of Left Lobe Atrophy in Long-standing Extrahepatic Portal Vein Obstruction.

Objectives: The aim of this study was to describe long-term changes in standard blood tests and ultrasound (US) findings in pediatric patients with Extrahepatic Portal Vein Obstruction (EHPVO) who have not undergone Meso-Rex Bypass (MRB) surgery.

Methods: US, laboratory, and endoscopic data of 77 patients were analyzed and compared at 2 different points in time: at initial workup and at most recent follow-up. Differences were assessed using McNemar and Wilcoxon tests, while correlations were evaluated using generalized estimating equations.

Ultrasonographic predictors of esophageal varices.

Objective: The aim of this study was to identify ultrasonographic predictors of esophageal varices (EVs) in children and adolescents with chronic liver disease (CLD) and extrahepatic portal venous obstruction (EHPVO).

Methods: This study evaluates 53 patients younger than 20 years with CLD or EHPVO and no history of bleeding or prophylactic EVs treatment. They were divided into 2 groups: group I (35 with CLD) and group II (18 with EHPVO).

Partial internal biliary diversion through a cholecystojejunocolonic anastomosis--a novel surgical approach for patients with progressive familial intrahepatic cholestasis: a preliminary report.

Background/purpose: The purpose of the study was to describe the initial experience with a novel approach to the surgical treatment of progressive familial intrahepatic cholestasis (PFIC), avoiding the creation of a permanent stoma.

Methods: Two teenaged patients, aged 15 and 17 years, underwent partial internal biliary diversion to treat uncontrollable pruritus associated with PFIC. The surgical technique involved the creation of an isolated jejunal conduit, anastomosed proximally in a terminolateral fashion to the gallbladder and distally to the ascending colon.
