Liver Transplantation for Unresectable Colorectal Liver Metastasis: Perspective and Review of Current Literature.

The treatment of unresectable colorectal liver metastasis (CRLM) has previously been limited to palliative chemotherapy. Traditionally, the role of liver transplant has not been associated with sufficient survival to justify a patient undergoing a major operation with the associated requirement for postoperative immunosuppression. With improvements in chemotherapy options, a certain subset of patients can experience stable disease for years, which has prompted investigation into the role of liver transplant in these patients.

Management of ectopic intestinal variceal bleeding following pancreatic transplant: Two cases.

Ectopic variceal bleeding is a potentially under recognized source of gastrointestinal (GI) hemorrhage. While vascular complications following pancreatic transplant are relatively common, the development of symptomatic ectopic venous varices has rarely been reported. We report two patients with a remote history of simultaneous kidney pancreas transplant (SPK) presenting two decades after transplant with an occult GI bleed.

Acute liver failure secondary to acute antibody mediated rejection after compatible liver transplant: A case report.

Background: The liver has traditionally been regarded as resistant to antibody-mediated rejection (AMR). AMR in liver transplants is a field in its infancy compared to kidney and lung transplants. In our case we present a patient with alpha-1-antitrypsin disease who underwent ABO compatible liver transplant complicated by acute liver failure (ALF) with evidence of antibody mediated rejection on allograft biopsy and elevated serum donor-specific antibodies (DSA).

Endoscopic removal of eroded laparoscopic adjustable gastric bands: a preferred approach.

Background: Complications related to laparoscopic adjustable gastric banding (LAGB) have led to an increased number of removals. An uncommon but potentially devastating complication is gastric band erosion into the gastric lumen, which can be managed by open surgical, laparoscopic, and endoscopic approaches.

Objective: A wide array of management techniques has been reported for removal of LAGB that have eroded into the stomach.

Stable isotopes in elephant hair document migration patterns and diet changes.

We use chronologies of stable isotopes measured from elephant (Loxodonta africana) hair to determine migration patterns and seasonal diet changes in elephants in and near Samburu National Reserve in northern Kenya. Stable carbon isotopes record diet changes, principally enabling differentiation between browse and tropical grasses, which use the C3 and C4 photosynthetic pathways, respectively; stable nitrogen isotopes record regional patterns related to aridity, offering insight into localized ranging behavior. Isotopically identified range shifts were corroborated by global positioning system radio tracking data of the studied individuals.
