[Factors relating to postoperative infections in cancer patients].
Some factors relating to the increasing prevalence of postoperative infections after gastroenterological surgery were investigated from the standpoint of both patients profile and isolated bacteria. Data were collected from 542 cancer patients comprising 39 with esophagus cancer, 229 with gastric cancer, 149 with hepato-biliary tract and pancreatic cancer and 125 with colon cancer. Respiratory infections after operations were most frequently caused by aging, disturbance of glucose tolerance and respiratory dysfunction, whereas with intraabdominal abscess the major factors were disturbance of glucose tolerance, hepatic dysfunction and respiratory dysfunction in this order. Two factors in the management of patients during operation were singled out as mainly contributing to infection: these were prolonged operative time as in the case of esophagus cancer or hepato-biliary tract and pancreatic cancer, and massive intraoperative bleeding as in hepato-biliary tract, pancreatic and gastric cancer. As isolated bacteria, the most frequent clinical isolates were MRSA, Enterococcus, P. aeruginosa and Enterobacter, and it is noteworthy that all of these were strongly resistant to all antimicrobial agents. The greater emphasis on prevention control of postoperative infections, therefore, should be focussed on aging, preoperative risk factors, surgical stress and the kinds of antimicrobial agents administered.
