Hypothesis: Live donor adult liver transplantation (LDALT) is a safe and efficacious treatment for patients with end-stage liver disease.Design: Case-control study.Setting: Hepatobiliary surgery and liver transplantation unit.Patients: From December 10, 1998, through April 10, 2000, a single team performed 15 LDALT procedures with 2 simultaneous living donor kidney transplants. During this period, 66 potential donors were screened and evaluated.Interventions: Potential donors were evaluated with 3-dimensional helical computed tomographic scan, including volume renderings for hepatic lobar volume, vascular anatomy, virtual resection planes, and morphologic features. Suitable donors undergo complete medical and psychiatric evaluation and preoperative arteriography.Main Outcome Measures: Donor demographics, evaluation data, operative data, hospital length of stay, and morbidity.Results: A total of 38 men (58%) and 28 women (42%) were evaluated with 15 donors participating in LDALT. Two additional donors provided kidney grafts for simultaneous transplantation at the time of LDALT. Thirtytwo donors (48%) were rejected for either donor or recipient reasons, and 10 patients (15%) elected not to participate after initial screening. Three-dimensional volume renderings by helical computed tomographic scan predicted right lobe liver volume within 92% of actual graft volume. Donor morbidity, including all complications, was 67% with no mortality. Residual liver regenerated to approximately 70% of initial volume within 1 week and 80% within 1 month after surgery.Conclusions: Donor evaluation is an important component of LDALT. Significant donor morbidity is encountered even with careful selection. To minimize donor morbidity, groups considering initiating living donor programs should have expertise in hepatic resection and vena cava preservation using the "piggyback" technique during liver transplantation.

Ataxia and myelopathy secondary to acquired copper deficiency are rare complications of major gastric resection. This is quite similar to the syndrome of vitamin B(12) deficiency. Vitamin B(12) repletion does not improve symptoms. Bariatric procedures such as gastric bypass surgery result in a similar functional anatomy of the proximal gut and may place more patients at increased risk. Early recognition and therapy with oral or parenteral copper may lead to a decrease in both neurologic and hematologic consequences.

Patients with intestinal failure and short bowel syndrome usually require chronic parenteral nutrition (PN). PN is associated with risks, including infections, vascular thrombosis, and liver disease. PN‐associated liver disease (PNALD) can progress from steatosis to chronic hepatitis and ultimately to cirrhosis. The etiology of PNALD is not completely understood. Therapies for PNALD include carbohydrate or lipid calorie reduction, antibiotics, or the use of ursodeoxycholic acid. When these efforts fail, therapeutic options are limited and liver transplantation may be required. The transition from a soybean‐ to a fish oil–based lipid formulation, such as the ω‐3 parenteral lipid formulation (Omegaven), has shown a dramatic reversal of PNALD within the pediatric population. This is the first report of a PN‐dependent adult in the United States complicated by PNALD and hepatic failure who had improvement of liver disease with an ω‐3 fish oil–based parenteral formulation.

Worldwide, there is an epidemic of obesity and overweight, with two‐thirds of Americans affected. A strong association exists between excessive body weight and nonalcoholic fatty liver disease (NAFLD), the most common etiology of abnormal liver function tests. Nonalcoholic fatty liver disease is a spectrum of liver disease, from a “bland” fatty infiltration to chronic hepatitis (nonalcoholic steatohepatitis or NASH), that can result in cirrhosis and organ failure. With the increasing prevalence of obesity in the world, the proportion of people affected by NAFLD is only expected to be parallel. Although primarily noted in obese individuals, NAFLD has also been associated with a number of surgical procedures, metabolic conditions, and medications. NASH is commonly underdiagnosed as most affected patients are symptom free, and routine screening is not performed. Noninvasive diagnostic testing is not sensitive in diagnosis or staging the severity of disease. Fatty infiltration and oxidative injury to the hepatocytes are believed to be the major factors behind the progression of disease from simple fatty infiltration of the liver to chronic hepatitis. Understanding the inflammatory pathways involved in NASH is a subject of extensive research. Currently, few proven treatment options exist, and controlled weight reduction is the only safe modality recommended for treatment of NASH.

Life-threatening hypophosphatemia (phosphorus < 1.0 mg/dL) has been reported only once after liver resection for tumor and was associated with a significant increase in postoperative complications. Hypophosphatemia is associated with reversible cardiac dysfunction, hypoventilation, and impaired immunity. The purpose of this study was to determine the incidence of hypophosphatemia after elective right hepatic lobectomy for live donor adult liver transplantation (
