Ultrasonically guided percutaneous aspiration biopsy of the pancreas.

One hundred and twenty-six patients had fine needle aspiration of the pancreas under ultrasonic guidance. The aspirates of 66 patients contained malignant cells. Two of 38 patients who had negative cytology subsequently were diagnosed at laparotomy as having carcinoma of the pancreas. The results of this study show that the sensitivity of the cytologic method was 97%, and the specificity and predictive value were 100%.

Cancer in chronic ulcerative colitis. Diagnostic role of segmental colonic lavage.

Saline colonic lavage in 74 patients with chronic ulcerative colitis was performed utilizing a commercially available dental irrigating unit through a polyethylene catheter in the biopsy channel of a colonoscope or through a sigmoidoscope via a lavage-aspirating double-lumen probe. Six patients were found with colonic carcinoma. Two diagnoses of malignancy were established by cytologic smears and cell block alone. Two patients had positive mucosal biopsies and cell block. One patient with a hepatic flexure carcinoma and a second patient with a malignancy proximal to the left colon stricture were missed by these techniques. Considering the established proclivity for carcinoma in these patients, it is felt that segmental lavage in areas of stricutre, grossly dostorted mucosa, or endoscopically inaccessible areas represents a valuable adjunct in the diagnosis of carcinoma in chronic ulcerative colitis.
