骶骨肿瘤骶神经切除后肛门直肠及膀胱排便功能的观察

The Evaluation of the Anorectal and Bladder Function after Sacrifice of the Sacral Nerves in Sacral Tumor Operation

目的:评价骶骨肿瘤手术骶神经切除后肛门直肠及膀胱排便功能。方法:对58例骶骨肿瘤手术中骶神经切除患者肛门直肠及膀胱排便功能分析。结果:58例中,23例保留双侧S1～S3神经根,86.96%和78.26%患者肛门直肠和膀胱排便功能于3个月内正常。3例保留单侧S1～S5神经根,3个月内肛门直肠及膀胱排便功能均正常。5例双侧S2～S5神经根切除,3个月内肛门直肠及膀胱排便功能均不正常。结论:保留至少一侧S1～S3神经根对患者肛门直肠及膀胱排便功能至关重要;肛门直肠及膀胱的功能恢复大多在3个月内。

Objective: To evaluate the anorectal and bladder functions after sacral nerve resection in the patients with sacral bone tumors. Methods: Bowel and bladder function in patients undergoing major sacral resection were analyzed retrospectively. Fifty-eight cases were enrolled in the study. Results: In all the cases with sacral nerves resection, 23 had preserved their bilateral S1～S3 nerve roots in the operation and the recovery rate of normal bowel and of bladder function in the patients within three months accounted for 86.96% and 78.26%, respectively; three cases had underwent unilateral sacrectomy, in which the contralateral sacral nerves were preserved, normal bowel and bladder functions were totally recovered within three months; five cases had sacrificed the bilateral S2～S5 nerve roots and all had abnormal bowel and bladder function within three months. Conclusion: Preservation of at least unilateral S1～S3 nerve roots is very important for the patients in keeping normal bowel and bladder function. Recovery of normal bowel and bladder function for the majority of patients is within three months.
