Background/Aims:
With the recent technical advancement to deliver high doses of radiation to a liver mass, radiation treatment has been increasingly used in patients with hepatocellular carcinoma. The aim of this study was to investigate the clinical characteristics of the gastrointestinal adverse effects after radiation therapy in patients with hepatocellular carcinoma.
Methodology:
Between 1994 to 2002, 153 patients with hepatocellular carcinoma have been treated with radiation therapy. Medical records were systemically reviewed.
Results:
Upper endoscopic examinations were done in 34 patients. Radiation-induced ulcers were found in the stomach (n=9) and duodenum (n= 14). Radiation-induced gastroduodenitis was found in 9 patients. Bleeding from radiation-related lesions in 11 patients (7.2%) was caused by gastroduodenitis (n=7), gastric ulcer (n=2), and duodenal ulcer (n=2). There were 7 patients with rebleeding. Bleeding was fatal in only one patient. Two patients with obstruction were treated by stent insertion. Two patients with perforation improved after surgical repair. Hematologic toxicity was found in 53 patients (34.6%) and hepatobiliary complications were found in 40 patients (26.1%). Radiation-induced pneumonitis was found in 3 patients (2%).
Conclusions:
We found that radiation-induced complications in patients with hepatocellular carcinoma are rather frequent. However, most complications were effectively managed by intensive treatments including endoscopic hemostasis, stent insertion and surgery.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Clinical manifestations of acute gastritis
The patient with acute gastritis may have a rapid onset of symptoms, such as epigastric pain or discomfort, dyspepsia, anorexia, hiccups, or nausea and vomiting, which can last from a few hours to a few days. Erosive or hemorrhagic gastritis may cause bleeding, which may manifest as blood in vomit or as...
