摘　　要：BACKGROUND Rectal cancer has increased in incidence,and surgery remains the cornerstone of multimodal treatment.Pelvic anatomy,particularly a narrow pelvis,poses challenges in rectal cancer surgery,potentially affecting oncological outcomes and postoperative complications.AIM To investigate the relationship between radiologically assessed pelvic anatomy and surgical outcomes as well as the impact on local recurrence following rectal cancer surgery.METHODS We retrospectively analyzed 107 patients with rectal adenocarcinoma treated with elective rectal surgery between January 1,2017,and September 1,2022.Pelvimetric measurements were performed using computed tomography(CT)-based two-dimensional methods(n=77)by assessing the pelvic inlet area in mm²,and magnetic resonance imaging(MRI)-based three-dimensional techniques(n=52)using the pelvic cavity index(PCI).Patient demographic,clinical,radiological,surgical,and pathological characteristics were collected and analyzed in relation to their pelvimetric data.RESULTS When patients were categorized based on CT measurements into narrow and normal/wide pelvis groups,a significant association was observed with male sex,and a lower BMI was more common in the narrow pelvis group(P=0.002 for both).A significant association was found between a narrow pelvic structure,indicated by low PCI,and increased surgical morbidity(P=0.049).Advanced age(P=0.003)and male sex(P=0.020)were significantly correlated with higher surgical morbidity.Logistic regression analysis identified four parameters that were significantly correlated with local recurrence:older age,early perioperative readmission,longer operation time,and a lower number of dissected lymph nodes(P<0.05).However,there were no significant differences between the narrow and normal/wide pelvis groups in terms of the operation time,estimated blood loss,or overall local recurrence rate(P>0.05).CONCLUSION MRI-based pelvimetry may be valuable in predicting surgical difficulty and morbidity in rectal cancer surgery,as indicated by the
