One hundred ninety-three consecutive colonoscopic procedures were carried out over a recent 1-year period. An overall success rate of 92.7% was achieved for 178 attempted polypectomies. Bleeding was a complication in two patients. No colonic perforations resulted from the procedures. The results represent experience gained with 1,450 colonoscopic polypectomies.
A case of hepatic metastasis with a clinical differential diagnosis of amebic and bacterial abscess is presented. Hepatic scanning with 67Ga-citrate did not diagnostically differentiate the lesion. Hepatic arteriography combined with a therapeutic trial of metronidazole proved useful in defining the lesion. An understanding of the pathophysiologic process involved in 67Ga scanning of hepatic lesions suggests a non-invasive method of discriminating among these clinical diagnostic possibilities.
