Methane gas in breath test is associated with non-alcoholic fatty liver disease.

Although the associations between a patient's body mass index (BMI) and metabolic diseases, as well as their breath test results, have been studied, the relationship between breath hydrogen/methane levels and metabolic diseases needs to be further clarified. We aimed to investigate how the composition of exhaled breath gases relates to metabolic disorders, such as diabetes mellitus, dyslipidemia, hypertension, and nonalcoholic fatty liver disease (NAFLD), and their key risk factors. An analysis was performed using the medical records, including the lactulose breath test (LBT) data of patients who visited the Ajou University Medical Center, Suwon, Republic of Korea, between January 2016 and December 2021.

Anterior segment congestion of a right liver lobe graft in living-donor liver transplantation and strategy to prevent congestion.

Background/purpose: A left lobe graft from a small donor will not usually fulfill the metabolic demands of a larger recipient in adult-to-adult living-donor liver transplantation (LDLT). One solution to this problem is to use a right lobe graft. However, the necessity of middle hepatic vein (MHV) outflow drainage from the anterior segment (AS) of a right lobe graft has not yet been clearly described in the literature.

Safety of anti-hepatitis B core antibody-positive donors for living-donor liver transplantation.

Serologic evidence of resolved hepatitis B virus (HBV) infection (HBV surface antigen negative, anti-HBV core antibody [HBc] positive) in a liver donor can be regarded as an occult infection with episomal HBV in the liver. The purpose of this study was to evaluate the safety of anti-HBc-positive living donors. Between March 2001 and January 2002, 127 donors underwent hepatectomy for living-donor liver transplantation at Asan Medical Center.

Approach to anatomic variations of the graft portal vein in right lobe living-donor liver transplantation.

Right lobe living-donor liver transplantation (LDLT) is often not attempted in donors with anomalous portal venous branching (APVB). The authors describe their experience with portal vein (PV) reconstruction in 17 cases of APVB in right lobe LDLT. From July 1997 to December 2001, 214 right liver LDLT were performed at the Asan Medical Center.
