Nonsteroidal anti-inflammatory drugs (NSAIDs), such as sulindac, have cancer chemopreventive properties by a mechanism that has been suggested to involve cyclooxygenase inhibition and reduction of prostaglandin (PGE2) levels in the target tissue. To test this hypothesis, we studied the effect of dietary sulindac sulfone (500-2000 ppm), a metabolite of(More)
Anal fistulas were recorded in 112 patients out of a series of 329 patients with Crohn's disease admitted to St Mark's Hospital for the first time between 1965 and 1976. Only 13 of 112 patients had small bowel disease alone. The remainder all had involvement of some part of the large bowel. There were 125 fistulas in the 112 patients. No treatment was(More)
Between 1957 and 1985, 886 women with Crohn's disease and an intact distal large bowel were seen at St. Mark's Hospital. Ninety of these patients developed a fistula between the vagina and anus or rectum at an average age of 34 years. The track of the fistula was clearly documented in 80 patients and was extrasphincteric or suprasphincteric in 36,(More)
Four hundred and fifty-three patients who underwent ileostomy and excisional large bowel surgery for chronic inflammatory disease at two teaching hospitals and 35 non-teaching hospitals within the North East Metropolitan Hospital Region during the years 1955-66 were surveyed through a study of hospital case records. The surgical results and complications(More)
269 patients with ulcerative colitis and a history of less than 6 months when first seen at St. Mark's Hospital in the decade 1966--75 have been followed for up to 11 years. The outcome has been correlated with the maximum extent of the disease observed within 3 months of presentation. 75 patients required hospital admission, 56 within a year of(More)
Myelosuppression is an important and potentially lethal complication of azathioprine treatment. The blood count has been reviewed in all patients treated with azathioprine for inflammatory bowel disease over 27 years in one hospital. Altogether 739 patients (422 with Crohn's disease, 284 with ulcerative colitis, and 33 with indeterminate colitis) were(More)
The cancer risk among 229 patients with extensive ulcerative colitis observed during January 1, 1966 to February 29, 1976 is correlated with the length of history and the histological findings in rectal and colonic biopsies. Five patients are known to have developed carcinoma. No carcinoma was observed in 578 patient years of follow-up within 10 years of(More)
The incidence of various cancers, especially non-Hodgkin lymphoma (NHL), is higher among patients who receive azathioprine for immunosuppression after organ transplants than in the general population. We have studied the risk of neoplasia after azathioprine in 755 patients treated for inflammatory bowel disease. The patients received 2 mg/kg daily for a(More)
The surgical treatment of 3163 patients seen at St Mark's Hospital with a single adenocarcinoma of the rectum in the years 1948-72 is described and the results analysed. In 2948 patients (93-2 per cent) the primary tumour was removed. The operative mortality fell from 7-0 per cent in the years 1948-52 to 2-1 per cent in 1968-72. The proportion of(More)
