Abstract

ABSTRACT Objective The aim of this study was to conduct a survey of the different complications of partial, total or extended sacrectomy for the treatment of spinal tumors. Method This study is a descriptive analysis of medical records from a series of 18 patients who underwent sacrectomy between 2010 and 2019 at a tertiary center specializing in spinal tumor surgeries. The variables analyzed were sex, age, hospitalization time, oncologic diagnosis, posterior fixation pattern, rate of complications, and Frankel, ASA and ECOG scales. Results Of the 18 patients, 10 (55.5%) were male and 8 (44.5%) were female, and the mean age was 48 years. The mean hospitalization time was 23 days. Of the 18 patients, 8 (44.5%) contracted postoperative infections requiring surgery. Perioperative complications included liquoric fistula (22.25%), hemodynamic instability requiring vasoactive drugs in the immediate postoperative period (22.25%), wound dehiscence (11.1%), acute obstructive abdomen (11.1%), occlusion of the left external iliac artery (11.1%), immediate postoperative death due to acute myocardial infarction (11.1%), and intraoperative death due to hemodynamic instability (11.1%). Conclusions Partial, total or extended sacrectomy is a complex procedure with high morbidity and mortality, even in centers specializing in the treatment of spinal tumors. Level of evidence IV; case series study.

Summary

Introduction

Sacral tumors are rare and may be malignant or benign. They represent 1% to 7% of all tumors of the spine. The response to chemotherapy and radiotherapy is not satisfactory for these tumors.[1,2] En bloc sacrectomy is currently the recommended treatment for malignant sacral tumors.[3,4,5,6,7] The term total sacrectomy refers to resection and attachment of the dural sac below bilateral S1, with the resection extending to L5, L4 and to the iliac region if necessary.[3,4,5,6,7]. As the diagnosis of various sacral tumors is complicated and usually delayed, due to the slow and indolent growth of most tumors, it is usually made incidentally, or when the tumor is already at an advanced stage.[9]
