RESUMEN
A 62-year-old man was referred to our hospital with enlargement of mucosa-associated lymphoid tissue (MALT) lymphoma of the rectum after the eradication of Helicobacter pylori. The patient was given a diagnosis of stage I MALT. Endoscopic observation revealed an enlarged rectal tumor with 3, 18 double trisomy. Rituximab monotherapy was given and complete remission was achieved. Rituximab monotherapy can be useful for MALT lymphoma of the rectum.

OBJECTIVE: Salivary chromogranin A (CgA) was recently reported to be a useful marker of mental stress. In this study, mental stress during upper gastrointestinal endoscopy was evaluated by measuring salivary CgA levels in young and elderly subjects. METHODS: The subjects were 9 healthy subjects aged less than 50 years (young group) and 15 subjects aged 70 years or older (elderly group). The heart rate, blood pressure, blood oxygen saturation level, and salivary CgA concentration were measured before and after upper gastrointestinal endoscopy and compared. RESULTS: In the young group, the CgA level decreased significantly (p<0.05) during endoscopy compared with the level during rest before endoscopy. In the elderly group, it also decreased significantly (p<0.05) during endoscopy compared with the level during rest before endoscopy. However, CgA levels were significantly higher (p<0.05) in the elderly group than in the young group both before and during endoscopy. The decrease in CgA levels was significantly greater (p<0.05) in the young group than in the elderly group. CONCLUSIONS: In this study, mental stress associated with endoscopy appears to be higher in elderly subjects than in younger subjects. Attention to complications due to increased stress is considered to be necessary in elderly patients during endoscopy.

Hepatic portal venous gas (HPVG) was detected by CT in a 64-year-old woman who suddenly complained of lower abdominal pain. However, the abdominal symptoms disappeared rapidly, and lower gastrointestinal endoscopy indicated only terminal ileitis. Conservative treatment alone was performed, and HPVG completely disappeared approximately 18 hours later. The use of CT proved to be useful for following the course of HPVG.
