Open resection for colorectal cancer was associated with high overall morbidity for both colon (37.2%) and rectal (40.2%) excisions, predominantly due to respiratory and cardiac complications.
Cohort (n=1,846)
PURPOSE: The aim of this study was to report the prevalence of postoperative complications and mortality of patients with colorectal cancer when treated by conventional surgery. METHODS: Morbidity and mortality following open resection for colorectal cancer were analyzed in 1,846 patients whose clinical, operative, and pathology data were prospectively documented over a 20-year period. RESULTS: Mortality following elective resection of the left and right colon was low, whereas overall morbidity was high (37.2 percent). Respiratory and cardiac complications were especially common. Incidence of clinically significant leakage was similar following right (0.5 percent) or left (1.1 percent) hemicolectomy. Incidence of anastomotic leakage was significantly higher after emergency right hemicolectomy (4.3 percent). Overall morbidity following excision of the rectum was high (40.2 percent). Respiratory and cardiac complications predominated. Incidence of clinically significant anastomotic leakage following anterior resection was low (2.9 percent). Over the years, there has been a decline in the number of patients with tumor demonstrated histologically in a line of resection, suggesting an improved local surgical clearance. CONCLUSIONS: These results following conventional surgery may be useful when evaluating new techniques.
Bokey et al. (Mon,) conducted a cohort in Colorectal cancer (n=1,846). Open resection (conventional surgery) was evaluated on Postoperative morbidity and mortality. Open resection for colorectal cancer was associated with high overall morbidity for both colon (37.2%) and rectal (40.2%) excisions, predominantly due to respiratory and cardiac complications.
