Fine needle aspiration biopsy in a diagnostic workup algorithm of salivary gland tumors.

The ultrasonic diagnosis of salivary gland diseases can give a more accurate information than clinical data alone. In diagnosis of the parotid gland diseases, it is necessary to differentiate clearly tumors from other diseases. When a tumor is suspected, its presence should be confirmed, and determined if it is solitary, multiple, unilateral or bilateral, intra or extraglandular, and benign or malignant. In the period of May 1998 to January 2001 ultrasound examinations were performed in 354 patients, FNAB with ultrasound control were performed in 152 patients with a mean age of 49.7 years. The ultrasound and cytologic findings were correlated with surgical and histologic findings. Results indicate that in patients with solid mass of the salivary gland, ultrasound examination confirmed the finding of salivary gland tumor in all patients (100%). In non-solid diseases of salivary glands the diagnostic accuracy was slightly lower. The use of ultrasound techniques in the study of salivary gland pathology is well justified, due to its capacity to provide high resolution and improving clinical diagnosis. FNAB is a simple quick, accurate and virtually complications free investigative modality. The data on its ability to distinguish between lesions requiring surgery or not are encouraging.

[Personal experiences with endoscopic polypectomies of the gastrointestinal tract]. / Unsere Erfahrungen mit endoskopischen Polypektomien im Gastrointestinaltrakt.

The authors performed from 1983 86 gastrofiberoscopic diathermocoagulations and 132 colonoscopic polypectomies. The finding of the high number of adenomas in the stomach - 22.35%/63.15% in diameter to 10 mm/-is surprising. As to complications they recorded in one case mucosal bleeding after gastrofiberoptic polypectomy and in one case a covered perforation of the sigmoid at the site of colonoscopic polypectomy. The discussion is devoted to the present views of the importance of the endoscopic polypectomy in the diagnosis and treatment of polyps in the gastrointestinal tract with the accentuation of the problems of the endoscopic polypectomy from the proximal part of the digestive tube. The authors state the necessity to keep this method for removal of the gastric hyperplasiogenous polyps and the polyps to 10 mm in diameter. Finally, the advantages of the endoscopic polypectomy: unpretentiousness, no risk for patient, high diagnostic and therapeutic value and the economy, as compared with transabdominal surgical approach, are stressed.
