高齢者に対する腹腔鏡下膀胱全摘除術の検討

Abstract

We compared the perioperative and oncological outcomes of laparoscopic radical cystectomy (LRC) between elderly patients over 75 years old and younger patients. Fifty-three patients underwent LRC between 2003 and 2014 at Tenriyorozu Hospital. Eighteen patients were classified as elderly (over 75) and the other 35 patients were considered young. The median operating time (434 vs 465 min, p＝0.35), estimated bloodloss (534 vs 525 g, p＝0.74), time to recommencing foodintake (7 vs 6 days, p＝1.00), and hospital stay (35 vs 32 days, p＝0.81) were not significantly different between the groups. Perioperative pyelonephritis was significantly more frequent in the elderly group (50% vs 20%, p＝0.02), while other complications were not significantly different between the two groups. The perioperative mortality rate was 0% in both groups. There were no significant differences between the elderly and young groups with respect to 2-year overall survival (74. 4% vs 91. 6%), cancer-specific survival (74. 4% vs 91. 6%), and recurrence-free survival (70.2% vs 81. 8%). LRC is a safe andefficient procedure for selected elderly patients.
