Management of Early-Stage Esophageal Adenocarcinoma by Endoscopic Spray Cryotherapy in the Setting of Portal Hypertension With Varices.

The use of endoscopic spray cryotherapy to manage pathological conditions of the esophagus has become increasingly common. This mucosal ablation technique is believed to carry a lower risk of bleeding than other modalities. A 71-year-old woman and a 64-year-old man with portal hypertension and varices were diagnosed with invasive esophageal adenocarcinoma during routine variceal surveillance.

Percutaneous image-guided splenic biopsy in the oncology patient: an audit of 156 consecutive cases.

Purpose: To assess the safety and diagnostic accuracy of percutaneous image-guided splenic biopsy in patients known to have or suspected of having malignancy.

Materials And Methods: Data from all image-guided splenic biopsies performed at a single institution from January 1992 to March 2007 were retrospectively reviewed. One hundred fifty-six splenic biopsies were performed in 147 patients (78 male and 69 female patients; mean age, 54.

Transarterial versus transhepatic portal vein embolization to induce selective hepatic hypertrophy: a comparative study in swine.

Purpose: Portal vein embolization (PVE) is used to induce liver hypertrophy for surgical candidates with marginal future liver remnant (FLR) volumes. We compared the feasibility, safety, and effectiveness of a transarterial approach for PVE (TA-PVE) with those of a transhepatic approach for PVE (TH-PVE) in a swine model.

Materials And Methods: Ten experimental pigs (TA-PVE, n = 5; TH-PVE, n = 5) and six controls (TA, n = 3; TH, n = 3) were studied.

Splenic arterial interventions: anatomy, indications, technical considerations, and potential complications.

Splenic arterial interventions are increasingly performed to treat various clinical conditions, including abdominal trauma, hypersplenism, splenic arterial aneurysm, portal hypertension, and splenic neoplasm. When clinically appropriate, these procedures may provide an alternative to open surgery. They may help to salvage splenic function in patients with posttraumatic injuries or hypersplenism and to improve hematologic parameters in those who otherwise would be unable to undergo high-dose chemotherapy or immunosuppressive therapy.
