Abstract
PURPOSE
The aim of this study is to investigate whether previous abdominal surgery (PAS) affected stage I-III colorectal cancer (CRC) patients who underwent radical resection.
METHODS
Stage I-III CRC patients who received surgery at a single clinical center from Jan 2014 to Dec 2022 were retrospectively included in this study. Baseline characteristics and short-term outcomes were compared between the PAS group and the non-PAS group. Univariate and multivariate logistic regression analyses were used to find risk factors for overall complications and major complications. A 1:1 ratio propensity score matching (PSM) was used to minimize the selection bias between the two groups. Statistical analysis was performed using SPSS (version 22.0) software.
RESULTS
A total of 5895 stage I-III CRC patients were included according to the inclusion and exclusion criteria. The PAS group had 1336 (22.7%) patients, and the non-PAS group had 4559 (77.3%) patients. After the PSM, there were 1335 patients in each group, and no significant difference was found in all baseline characteristics between the two groups (P > 0.05). After comparing the short-term outcomes, the PAS group had a longer operation time (before PSM, P < 0.01; after PSM, P < 0.01) and more overall complications (before PSM, P = 0.027; after PSM, P = 0.022) whether before or after PSM. In univariate and multivariate logistic regression analyses, PAS was an independent risk factor for overall complications (univariate analysis, P = 0.022; multivariate analysis, P = 0.029) but not for major complications (univariate analysis, P = 0.688).
CONCLUSION
Stage I-III CRC patients with PAS might experience longer operation time and have a higher risk of postoperative overall complications. However, it did not appear to significantly affect the major complications. Surgeons should take steps to improve surgical outcomes for patients with PAS.
