Abstract
Thirty operated cases of colorectal cancer in aged patients over 80 years old were studied with reference to their characteristics, surgical outcomes, postoperative laboratory findings, and postoperative complications.
1) Well-differentiated advanced colonic carcinomas were predominant; and emergency operation for ileus or perforation represented 33.3%. 2) Resection rate was 96.7%; curative resection rate, 79.3%; and 5-year survival rate in curative resections, 54.3%. 3) Postoperative complications occurred in a high rate of 51.7%. The complications were commonly found in a patient group having 4 to 5 abnormal laboratory findings among 8 items and perforation, too. 4) Preoperative abnormal laboratory findings were commonly seen in terms of the lung and nutrition, which well corresponded with frequent occurrence of pneumonia and anastomotic breakdown. Moreover, encephalopathy or phrenophathy characteristic of aged people was also frequently observed. 5) It is thought that safe operation and postoperative management in response to each patient, which are able to prevent these postoperative complications and operative death, are necessary.
