Incidence, pattern, and etiology of elevated liver enzymes in pediatric inflammatory bowel disease.

OBJECTIVES: Patients with inflammatory bowel disease (IBD) often develop elevated liver enzymes (ELE), which are frequently a benign, transient finding, but may be related to treatment or IBD-associated liver diseases. Distinguishing benign from pathologic ELE is crucial for focused diagnostic and therapeutic interventions. We sought to characterize the incidence, character, chronicity, degree, and etiology of ELE in children with IBD. METHODS: Institutional review board-approved retrospective review of all of the patients with IBD (2-21 years) seen between October 2009 and October 2012 with >9 months of follow-up were included in the study. We examined body mass index, disease activity, extent, phenotype, concurrent medications, and character, chronicity, degree of enzyme elevation, and final diagnosis. RESULTS: A total of 219 of 514 patients with IBD had ≥1 episode of ELE. Five patients were excluded for preexisting liver disease, leaving 214 patients (Crohn disease [CD]: 14.8 ±â€Š3.5 years, 46% girls; ulcerative colitis [UC]: 14.4 ±â€Š4.2 years, 37% girls). One hundred forty-eight patients (69%) had a hepatic, 17 (8%) cholestatic, and 49 (23%) mixed character of ELE. There were no significant differences in character, chronicity, or degree of ELE between CD and UC (P = 0.71, P = 0.58, P > 0.33). Of the 128 patients with sufficient data to determine chronicity, 98 (77%) had transient elevations, (CD: n = 66, 75% and UC: n = 32, 80%). Episodes of ELE were idiopathic in 87% of patients with IBD. A final diagnosis of idiopathic ELE was associated with a lower degree of ELE elevation (P < 0.0001). CONCLUSIONS: Pediatric patients with IBD commonly experience transient, idiopathic ELE. Our findings suggest that higher degrees of ELE, specifically alanine aminotransferase, are associated with an etiology that requires more extensive evaluation.

Migration of Gastric Varix Coil After Balloon-Occluded Antegrade Transvenous Obliteration.

This is a case report of a man with alcoholic cirrhosis who underwent transjugular intrahepatic portosystemic shunt and balloon-occluded antegrade transvenous obliteration for gastric fundal varices in 2017. After almost a year, we found extensive migration of the coil into the gastric fundus on upper endoscopy. Continued vigilant surveillance endoscopy may help detect this complication.

Pancreatic Cystic Lesions: Pathogenesis and Malignant Potential.

Pancreatic cancer remains one of the most lethal cancers despite extensive research. Further understanding of precursor lesions may enhance the ability to treat and prevent pancreatic cancer. Pancreatic cystic lesions (PCLs) with malignant potential include: mucinous PCLs (intraductal papillary mucinous neoplasms and mucinous cystic neoplasm), solid pseudopapillary tumors and cystic neuroendocrine tumors. This review summarizes the latest literature describing what is known about the pathogenesis and malignant potential of these PCLs, including unique epidemiological, radiological, histological, genetic and molecular characteristics.
