L'UTILIZZO DELLE SUTURATRICI MECCANICHE NEL TRATTAMENTO CHIRURGICO DEL CANCRO DEL RETTO NELL'ANZIANO

The aim of this study was to analyze the changes in surgical treatment of rectal cancer and in postsurgical complications as a result of the introduction of staplers in surgical practice, with particular reference to elderly patients (> or = 75 years). Since 1976, 320 patients have undergone rectal surgery in our department (207 colo-rectal or colo-anal anastomoses and 113 Miles operations have been performed). The patients were subdivided into two groups on the basis of age (> or = and < 75 years) and then further divided into subgroups operated on before and after 1983 (the year staplers were introduced). The morbidity rate (fistulas) was 16% in patients < 75 years old and 12% in elderly patients (P = n.s.); the mortality rate was 1% in patients < 75 years old and 12% in the more elderly group (P < 0.001). The utilization of staplers in surgical treatment of rectal cancer allows the surgeon to perform sphincter-sparing resections even in elderly patients without any changes in specific morbidity. Nevertheless, the complications are more severe in the elderly, with a higher mortality rate.
