摘要:

&NA;Colonscopy resulted in detection of cancers in 10 per cent of patients examined. These cancers were at an earlier stage than expected, possibly due to colonoscopy. Many were small, suggesting that the most fruitful approach to eradicating cancer is through the management of polyps. The indications for colonoscopy should remain the clinical or radiologic suspicion of colonic cancer.These encouraging results suggest that colonoscopy offers a significant advance in cancer detection. Further results from much larger series are eagerly awaited to see whether they confirm these preliminary findings.

摘要:

&NA;Preoperative LDH, CPK, alkaline phosphatase and liver scan results were compared with the presence or absence of hepatic metastases at operation in 124 laparotomies in 123 patients with colorectal carcinomas during a three‐year period.The overall accuracy rates for the four tests ranged from 74 to 84 per cent. The false‐negative rates were acceptably low (9‐13 per cent) for all but the CPK determination. The false‐positive rates were unacceptably high for all four tests (38 to 60 per cent). A “metastatic score” for reducing the high false‐positive rate is described.In view of the high false‐positive rates of preoperative screening tests, laparotomy is presently the most accurate method of diagnosing hepatic metastases.

摘要:

&NA;We have reported long‐term results in the cases of 42 patients following total colectomy and ileorectal anastomosis for inflammatory bowel disease. In this group, 35 patients had Crohn's disease and seven had ulcerative colitis. Five of those seven patients with ulcerative colitis had carcinoma of the colon at the time of colectomy. A diverting loop ileostomy was constructed in 14 of the 35 patients who had Crohn's colitis at the time of operation, and none of these patients had any anastomotic leakage either before or after the ileostomy was closed. However, there were three patients with Crohn's colitis in whom anastomotic leaks developed postoperatively; all three patients died. In the group with ulcerative colitis, one patient had an anastomotic leak but there was no operative mortality. Of the 29 patients with Crohn's disease followed for one to 18 years, 12 (41 per cent) developed recurrences in the ileum and/or rectum, and seven of these patients had to have their anastomoses taken down.
