Abstract
A 66-year-old man visited another hospital complaining of abdominal distention. Close examination revealed ileus, and he was referred to our hospital for detailed examination and treatment. Abdominal CT revealed thickening of the peritoneum and mesenterium, and ascites. Gastrografin enema revealed stenosis of the jejunum. We suspected intestinal tumor, possibly malignant. Therefore, a diagnostic laparoscopy was performed. Laparoscopy revealed multiple white nodules on the peritoneum and wall of the intestine, and mucous ascites with slightly muddy yellow fluid. Laparoscopic biopsy of the lesions was performed for pathological diagnosis and selection of the appropriate treatment protocol. The pathological diagnosis was peritoneal malignant mesothelioma. Thus diagnostic laparoscopy was useful for detecting peritoneal malignant mesothelioma.
