骶骨肿块可以通过前进、后进或联合手术方式进行切除。通过仅采用后进方式实施全部骶骨切除，手术时间缩短，组织损伤最小，且并发症风险降低。本研究旨在介绍我们在26例患者中采用后进方式实施全部骶骨切除的经验，并评估其在我中心的临床结果。本回顾性研究考察了26例不同骶骨肿块病变的患者的临床进展、手术反应和结果。我们从医院记录中获取了患者信息。研究对象中有14名男性（占54%），12名女性（占46%），平均年龄为49.8岁。大多数病例的BMI正常，而有6例超重。12例患者进行了高位骶骨切除，14例进行了中位骶骨切除。除疼痛外，发现9例患者有运动功能障碍，5例患者有括约肌功能障碍。11例患者在术前进行了栓塞治疗。最常见病变为占8例的脊索瘤，占4例的恶性周围神经鞘肿瘤，占3例的巨细胞瘤，占3例的孤立浆细胞瘤。手术后仅有一例患者出现暂时的部分运动障碍。没有发生脑脊液泄漏。5例患者出现局部复发，1例患者出现远处转移。通过后进方式实施骶骨切除以治疗大型或巨大骶骨肿瘤是可行且安全的，可以减少发病率，并且对总体生存率没有显著影响。 版权所有 © 2023 Elsevier Inc. 保留所有权利。

Sacral masses can be removed using anterior, posterior, or combined approaches. Achieving total sacrectomy through a posterior-only approach results in a shorter procedure time, minimal tissue damage, and a reduced risk of complications.In this study, we aimed to share our experience with performing total sacrectomy using a posterior-only approach in 26 patients and to assess their clinical outcomes at our center.This retrospective study examines the clinical progression, surgical response, and outcomes of 26 patients with various sacral mass pathologies. We accessed patient information from our hospital records.The study included fourteen men (54%) and twelve women (46%), with an average age of 49.8 years. Most cases had a normal BMI, while six were overweight. Sacrectomy was performed at a high level in 12 patients and at a middle level in 14 patients. In addition to pain, motor deficits were observed in 9 patients, and sphincter dysfunction was found in 5. Preoperative embolization was conducted for 11 patients. The most prevalent lesions were Chordoma (8 patients), Malignant Peripheral Nerve Sheath Tumor (4 patients), Giant cell tumor (3 patients), and Solitary plasmacytoma (3 patients). Only one patient experienced a temporary partial motor deficit after surgery. There were no instances of cerebrospinal fluid leakage. Five patients experienced local recurrence, and one had distant metastasis.Performing sacrectomy for large or giant sacral tumors through a posterior approach is both feasible and safe, resulting in reduced morbidity and no significant change in overall survival.Copyright © 2023 Elsevier Inc.
