Results of surgical palliation for cancer of the head of the pancreas and periampullary region.

Between 1977 and 1986, 101 patients underwent surgical bypass for periampullary carcinoma. The hospital mortality rate was 18 per cent and the morbidity rate 43 per cent. Mortality was not influenced by the extent of the tumour. Survival rates at 1,2 and 3 years were 28, 9 and 4 per cent, respectively. The median survival time was 17 months for localized tumours, 10 months for those that had invaded surrounding tissues, 6 months in the presence of lymph node involvement and 3 months with distant metastasis. The quality of survival was good for most patients with localized tumours but poor for those with parenchymal metastasis, in whom palliation was transient for 85 per cent and effective for less than half of their survival time for 60 per cent. These results suggest that patients with distant metastasis but without impending duodenal obstruction should undergo palliation by endoscopic or percutaneous routes while those with less advanced disease or with duodenal involvement remain candidates for surgical bypass.
