Does emergency surgery affect resectability of colorectal cancer?
OBJECTIVE
Emergency surgery for colorectal cancer is common in daily practice, and is mainly implied by bowel obstruction. It is related to increased morbidity and mortality. Its relation with the stage and respectability of the disease is uncertain. This study aims to further clarify these parameters.


METHODS
Over the past 24-year period 121 patients had an emergency operation (12%) from a total of 1009 patients with colorectal carcinoma. There were 59 men (48.8%) and 62 women (51.2%) with a mean age of 68 years (range 21-93); 61 patients (50.4%) were > or = 70-years-old. The data of all these patients were studied retrospectively in comparison with those who underwent elective surgery. Emergency cases were further divided into two age groups (> or = 70 and < 70 years) and compared. The tumour location was mainly in the left colon, whereas obstruction was the predominant reason for acute presentation.


RESULTS
On operation, absence of macroscopic spread was noted in 57.8% of emergency cases and 72% of elective cases (p < 0.05). The resectability rates were 75% and 90% respectively (p < 0.05), and were not significantly affected by the age factor. There were no differences in the grade of malignant cell differentiation or in the depth of microscopic invasion (p > 0.05) in either group. For emergency operations, the morbidity was 20% (24 patients) and the 30-day mortality rate was 5.8% (7 patients). Both parameters were higher in patients > or = 70-years-old.


CONCLUSIONS
Emergency surgery for colorectal carcinoma is related to lower resectability and to higher--but acceptable--postoperative morbidity and mortality rates, when compared with elective surgical management.
