Abstract
BACKGROUND: This study aims to evaluate the predictive level of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) risk calculator for post-appendectomy complications. METHODS: A total of 292 patients who were hospitalized for general appendectomy were included in the study. The age range of the patients was 18-76 years (mean: 35.3±13.6 years). The mean body mass index was 25.8±4.6. Twenty data points were entered into the ACS-NSQIP surgical risk calculator (SRC), which yielded the 17 most common complications and the average LOHS. Compli-cations encountered in 30-day follow-up were categorized according to the complications predicted by SRC. The actual and observed complication rates and LOHS were compared RESULTS: Post-operative complications developed in 13.4% of the patients, surgical site infection in 11.3%, serious complications in 3.1%, and readmission in 2.1%. Serious complications included pneumonia, sepsis, cardiac complications, and renal failure. The mean LOHS was 1.91±1.64 days (range: 1-14 days). No thromboembolism or mortality was observed. When the comparison of compli-cations using SRC was made with the ROC curve, the predictive value of SRC was 84.2% for any complication, 86.7% for serious complication, 47.6% for surgical site infection, 95.9% for renal failure, 99.0% for resurgery, and 88.3% for sepsis. CONCLUSION: Although it is rare to see complications after simple appendectomy, it is known that complication rates increase sig-nificantly in the elderly, the obese, and those with comorbidities. Tools such as SRC will be beneficial for patients with these risk factors.
