Assessment of age-specific safety of laparoscopic surgery in elderly patients with ovarian tumors.

Aim: We assessed the age-specific safety of laparoscopic surgery in elderly patients with ovarian tumors.

Material And Methods: We performed a retrospective analysis of 55 elderly patients treated by laparoscopic salpingo-oophorectomy under the diagnosis of an ovarian tumor between January 2009 and December 2014. We divided patients into three groups: "young-elderly" (aged 65-74), "old-elderly" (aged 75-84), and "super-elderly" (aged 85-105) and assessed clinical characteristics, surgical results and postoperative course. Statistical significance of categorical variables was examined by the Student's t-test, Mann-Whitney U test, or Fisher's exact test. Multiple regression analysis was used for multivariate analysis.

Results: Of a total of 55 patients who underwent laparoscopic surgery, there were 36 patients in the young-elderly group, 17 in the old-elderly group, and two in the super-elderly group. Statistical analysis was performed between the young-elderly and the old-elderly groups because of the small number in the super-elderly group. More frequent comorbidities were found in the patients in the old-elderly than in the young-elderly group (Fisher's exact test, P = 0.007). There were no significant differences in operative time, estimated blood loss and postoperative hospital stay between the young-elderly and old-elderly groups. Intraoperative complications only occurred in the young-elderly group. Postoperative complications occurred in all groups.

Conclusions: Although patients in the old-elderly group had a significantly higher risk for surgery, they had equivalent surgical results to the young-elderly group for laparoscopic salpingo-oophorectomy.
