Popis: The number of geriatric patients is expected to grow 3-fold over the next 30 years, and as many as 50% of the surgeries done in the United States may occur in geriatric patients. Geriatric patients often have increased comorbidities and more often present in a delayed manner for acute appendicitis. The aim of this study was to evaluate outcomes between geriatric patients and younger patients undergoing appendectomy, hypothesizing that geriatric patients will have a higher risk of abscess and/or perforation, conversion to open surgery, postoperative intra-abdominal abscess, and 30-day readmission.The 2016 to 2017 American College of Surgeons National Surgical Quality Improvement Program Procedure Targeted Appendectomy database was queried for patients with preoperative image findings consistent with acute appendicitis. Geriatric patients (age ≥65 years old) were compared with younger patients (age65 years old). A multivariable logistic regression model was used for analysis.From 21,586 patients undergoing appendectomy, 2,060 (9.5%) were geriatric patients. Compared with the younger cohort, geriatric patients were less likely to have leukocytosis (59.0% vs 65.8%, P.001) and more likely to have a tumor and/or malignancy involving the appendix on final pathology (2.0% vs 0.8%, P.001), an unplanned laparoscopic conversion to open surgery (4.2% vs 1.5%, P.001), and 30-day readmission (7.0% vs 3.3%, P.001). Geriatric patients had a longer median length of stay (2 vs 1 days, P.001) and higher mortality rate (0.5% vs0.1%, P.001). After adjusting for covariates, there was an increased associated risk of intraoperative abscess and/or perforation (odds ratio 2.23, 2.01-2.48, P.001) and postoperative intra-abdominal abscess (odds ratio 1.43, 1.12-1.83, P = .005) but no difference in associated risk for mortality (odds ratio 2.56, 0.79-8.25, P = .116), compared with the younger cohort.Nearly 10% of laparoscopic appendectomies are done on geriatric patients with geriatric patients having a higher rate of conversion to open surgery and tumor and/or malignancy on final pathology. Geriatric patients have an associated increased risk of intraoperative perforation and/or abscess and postoperative intra-abdominal abscess but have similar risk for mortality compared with nongeriatric patients undergoing laparoscopic appendectomy.
