title: Implications of emergency operations on the colon.
abstract: The records of 137 patients undergoing elective colonic operations and 45 patients requiring emergency large bowel operations were reviewed. The mortality rate was 37.8 percent after emergency operations compared with 5.1 percent after elective operations (p less than 0.001). Patient age was not a significant prognostic variable although physiologic status of the patient had a high correlation with both morbidity and mortality. Complications followed 86.7 percent of the emergency operations and 57.7 percent of the elective operations (p less than 0.001). Respiratory failure, renal and hepatic dysfunction, and cardiac events more frequently followed emergency colonic operations. Intraabdominal complications developed after 57.8 percent of the emergency operations compared with 29.9 percent of the elective operations (p less than 0.005). Colonic resection and primary anastomosis in the elective setting was associated with a 7.9 percent mortality rate. A large bowel anastomosis during an emergency operation resulted in a 70 percent mortality rate (p less than 0.001). When emergency colonic operation included creation of a colostomy the mortality rate was 34.4 percent. Although this mortality rate was substantial, it was significantly better than the 70 percent rate that followed attempted anastomosis under unfavorable circumstances (p less than 0.02).
