[Show abstract][Hide abstract] ABSTRACT: The aim of this study was to evaluate the clinical characteristics and treatment outcomes, including surgical safety, in patients over 80 years of age who underwent an appendectomy.
This study involved 160 elderly patients who underwent an appendectomy for acute appendicitis: 28 patients over 80 years old and 132 patients between 65 and 79 years old.
The rate of positive rebound tenderness was significantly higher in the over 80 group (P = 0.002). Comparisons of comorbidity, diagnostic tool and delay in surgical treatment between the two groups were not statistically different. American Society of Anesthesiologists score was significantly higher in the over 80 group than in the 65 to 79 group (2.4 ± 0.5 vs. 1.6 ± 0.5; P < 0.00005). Comparisons of operative times and use of drainage between the two groups were not statistically different. In the pathologic findings, periappendiceal abscess was more frequent in the over 80 group (P = 0.011). No significant differences existed between the two groups when comparing the results of gas out and the time to liquid diet, but the postoperative hospital stay was significantly longer in the over 80 group (P = 0.001). Among the postoperative complications, pulmonary complication was significantly higher in the over 80 group (P = 0.005). However, operative mortality was zero in each group.
In case of suspicious appendicitis in elderly patients, efforts should be made to use aggressive diagnostic intervention, do appropriate surgery and prevent pulmonary complications especially in patients over 80 years of age.
