Narrow pelvis has been considered an adverse factor for postoperative and oncologic outcomes after rectal cancer surgery. The aim of this study was to investigate the validity using only axial CT scan images calculate pelvic cross-sectional area prediction surgery.The medical records patients who underwent surgery were reviewed analyzed retrospectively. Axial used measure area. Pelvic surgical site infection (SSI), positive resection margin, early local recurrence adopted as end-points analyze impact pelvimetry on outcome.The mean 84.3 ± 10.9 cm2. Males had significantly smaller areas than females (P < 0.001). Comparing according outcomes, results indicated that with SSI failure (positive margin or within 1 year) have cross-sectional-area failure-free = 0.013 P 0.031). A calculated 88.8 cm2 determined cutoff value and/or failure, which significant in a validating analysis.The obtained from routine image associated SSI, recurrence. It might be intuitive, feasible, easily adoptable method predicting outcomes.
