Interfractional diaphragmatic position variation according to stomach volume change during respiratory-gated radiotherapy for hepatocellular carcinoma.

Purpose: We evaluated the correlation between stomach volume change and interfractional baseline shifts of the diaphragm in image-guided radiotherapy (IGRT) for hepatocellular carcinoma (HCC).

Materials And Methods: Twenty-four patients with HCC underwent ten fractions of IGRT, and a total of 240 cone beam computed tomography (CBCT) and on-board imager (OBI) kV image sets were acquired. These image sets were retrospectively analyzed.

Prevalence of colorectal adenomas in asymptomatic young adults: a window to early intervention?

Objective: The prevalence of colorectal adenoma is increasing in the average-risk population. However, little research is available on colorectal adenoma in young adults under age 40. The aim of this study was to investigate the prevalence and risk factors of colorectal adenoma in 20- to 39-year-old adults.

[A case of superior mesenteric venous thrombosis due to protein C deficiency in a patient with duodenal ulcer bleeding].

Mesenteric venous thrombosis is a clinically very rare disease, and may cause bowel infarction and gangrene. Difficulty in the diagnosis the disease due to its non-specific symptoms and low prevalence can cause a clinically fatal situation. Mesenteric venous thrombosis may be caused by both congenital and acquired factors, and protein C deficiency, which is a very rare genetic disorder, is one of many causes of mesenteric thrombosis.
