Postoperative mortality and morbidity in older patients undergoing emergency right hemicolectomy for colon cancer.

Introduction: Even with the advances in surgical technique and perioperative care, morbidity and mortality after colorectal cancer surgery remain considerable, and patients (pt) who present as an emergency have an even higher mortality and morbidity rate.

Methods: A total of 35 pt with caecum or ascending colon cancer between January 2007 and June 2015, three departments in Italy and in Poland, were included in the study. The intention of surgery in all cases was curative resection with ileo-colic anastomosis. Comparative statistical analysis was performed.

Results: Acute bowel obstruction was the major complication of CRC that led to an emergency hemicolectomy. Postoperative mortality and morbidity rates were in total 12.5 and 28.1%, respectively. All the deaths happened in Poland. Of the pt, 42.8% had morbidity in Poland and 16.6% in Italy. Out of the pt, 25% presenting with perforation: 25% died, 25% had wound dehiscence, 12.5% had pulmonary oedema, and 12.5% had an intra-abdominal abscess. The mean age of the pt with complications in Poland and in Italy was 79.3 and 72.0 years, respectively.

Conclusion: We observed that particularly lethal combination is older age, perforation with peritonitis and advanced stage of the cancer.
