Physical status is the principal determinant of outcome after emergency admission of patients with colorectal cancer.

A prospective study of 825 consecutive patients with colorectal cancer presenting to three general surgeons in a district general hospital over a 10-year period are reported. In all, 735 patients had an operation and are grouped according to whether their operation was within 24 h of admission (n = 63), more than 24 h after admission (n = 151), or elective (n = 521). Operative mortalities for these groups were 15.9%, 15.2% and 6.5%, respectively, significantly higher in both the emergency groups. Delayed surgery to allow complete resuscitation did not improve the operative mortality when compared with those patients having urgent surgery. Both groups of emergency patients, delayed (27%) urgent (19%), showed poorer 5-year survival than the electively treated patients (36%), many dying of non-cancer causes. Patients who undergo emergency surgery for colorectal carcinoma are more likely to be in poorer physical condition than patients undergoing elective surgery for the same condition. It appears that the physical status is the principal determinant of outcome after emergency colorectal surgery rather than any other factor.
