Non-operative Treatment of Gastric Ulcer Perforation with Contrast Leakage in an Elderly Patient / 대한내과학회지

Peptic ulcer remains an important public health concern due to an aging society and the increasing use of non steroidal anti-inflammatory drugs (NSAIDs). Perforated peptic ulcer is a major life-threatening complication of peptic ulcer. While the preferred treatment is surgery, conservative treatment does not result in significantly different outcomes in young, hemodynamically stable patients. However, conservative treatment of perforated peptic ulcer is associated with high failure rates in elderly patients. We report a case of an 87-year-old patient with a perforated peptic ulcer with contrast agent leakage. The patient was treated conservatively without complications; the treatment included non per os (NPO), insertion of a Levin tube, intravenous antibiotics, and a proton pump inhibitor.

Case of Malignant Mesothelioma of the Peritoneum and Pleura / 대한내과학회지

Malignant mesothelioma is a rare aggressive tumor and arises from mesothelial cells in the pleural, peritoneal and pericardial cavities. Median survival is -1 year and the incidence is approximately 0.7 per million persons, and is increasing annually in Korea. It is difficult to diagnose malignant mesothelioma because of nonspecific symptoms, signs and laboratory findings. It needs to be confirmed by histological examination and immunohistochemistry. There is no case report of malignant mesothelioma of the peritoneum and pleura in Korea. We report a rare case of malignant mesothelioma with simultaneous involvement of the peritoneum and pleura in a 75-year-old man without evidence of asbestos exposure.
