Abstract
INTRODUCTION: This paper assessed the association between operative approach and postoperative in-hospital mortality in elderly patients undergoing emergency abdominal surgery. Patients undergoing emergency laparotomy have high morbidity and mortality rates. One-third of patients requiring emergency surgery are over 75 years old, and their in-hospital mortality rate exceeds 17%. Fewer than 20% of emergency abdominal operations in the UK are attempted laparoscopically, and only 10% are completed laparoscopically. Little is known about how laparoscopic emergency surgery in the elderly might affect outcomes. METHODS: An observational UK study was performed using the prospectively maintained National Emergency Laparotomy Audit (NELA) database. Operative approach, NELA risk-prediction score and in-hospital mortality were recorded. The effect of operative approach on in-hospital mortality was analysed, both on a national basis and in a high-volume laparoscopic centre. RESULTS: A total of 47,667 patients were included in the study, of whom 15,068 were over 75 years of age. Nationally, surgery was completed by the laparoscopic approach in 7.8% of patients aged over 75; both crude mortality (9.2%) and risk-adjusted mortality (7.1%) were significantly reduced (p<0.0001). In our unit, surgery was completed laparoscopically in 48.4% of patients aged over 75; both crude mortality (6.6%) and risk-adjusted mortality (3.3%) were significantly reduced (p<0.0001). CONCLUSION: Laparoscopy in emergency surgery has been shown in this study to significantly reduce in-hospital mortality in elderly patients and should be embraced in every centre dealing with emergency abdominal surgery.
