RA05.09: THE INFLUENCE OF AGE ON OVERALL SURVIVAL AND COMPLICATIONS AFTER IVOR LEWIS TOTALLY MINIMALLY INVASIVE ESOPHAGEAL SURGERY

Abstract Background Worldwide, the number of elderly patients suffering from esophageal cancer is increasing due to the increasing incidence of esophageal cancer and increasing life expectancy of the general population. The effect of age on morbidity, mortality and survival after Ivor Lewis totally minimally invasive esophagectomy (TMIE) with curative intention are not well known since elderly patients have been excluded in randomized trials. Methods A retrospective analysis of a prospectively documented database from December 2010 to June 2017 was performed, including all patients who underwent Ivor Lewis TMIE with curative intent for esophageal cancer in three Dutch hospitals. Patients younger than 75 years (younger group) were compared to patients aged 75 years or older (elderly group). Postoperative complications, in-hospital mortality, 30 and 90 days mortality, long-term complications and survival were compared between these two groups. Results Four hundred and forty-six patients were included, 89 patients in the elderly group and 357 patients in the younger group. In the elderly group, a significantly higher incidence of non-surgical complications (77.5% versus 66.7%; P = 0.048), cardiovascular complications (24.7% versus 14.0%; P = 0.014) and delirium (27.0% versus 11.8%; P = 0.000) was found. There was no significant difference in surgical complications, overall complications, 30-day mortality, 90-day mortality, 1-year survival and 2-year survival. Conclusion Although Ivor Lewis TMIE in elderly patients is associated with a higher rate of non-surgical complications, it can be safely performed without increasing postoperative mortality.
