Popis: Aim This study aims to investigate the association of patient age with defecation disorders and anal function after lower rectal cancer surgery. Methods We retrospectively reviewed the data of 141 consecutive patients with lower rectal cancer who underwent sphincter‐preserving operation. The patients were classified into five categories by age thresholds at 65, 70, 75, 80, and 85 years, for disaggregate analysis. Anal manometry was used for measuring the maximum resting pressure, high‐pressure zone, and maximum squeeze pressure. Anal manometry was performed preoperatively and at 3, 6, 9, and 12 months postoperatively. The Wexner and low anterior resection syndrome scores were assessed at 1, 3, 6, 9, and 12 months after rectal surgery or stoma closure for patients with ileostomy. Results The data of 117 patients were reviewed. No significant differences were found between the younger and elderly groups in any characteristics across the six age groups. The preoperative intra‐anal pressures of the elderly patients were slightly lower than those of the younger patients; however, there was no significant difference in the course of postoperative intra‐anal pressures. Defecation disorder, as measured by the Wexner and low anterior resection syndrome scores, improved significantly in elderly patients compared to younger patients. Conclusion There was no significant difference in the course of postoperative intra‐anal pressures between the elderly and younger patients. However, defecation disorders in elderly patients significantly improved compared with younger patients. Sphincter‐preserving operation can be a viable treatment option for active elderly patients.
The intra‐anal pressures were the same between the younger and the elderly after rectal surgery; however, defecation disorders in elderly patients significantly improved compared with those in younger patients. These new findings may help determine the optimal surgical procedure for lower rectal cancer in elderly patients. Sphincter‐preserving operation can be a good treatment option for active elderly patients.
