The Treatment Efficacy of Transparasacral Approach For Presacral Tumor: A Single Center Experience

Abstract

Background: Presacral tumors, also known as retrorectal tumors, locate in the presacral space and are clinically rare and the approaches for the diagnosis and treatment of presacral tumors are still deficient. The four accepted surgical approaches for presacral tumors include transabdominal approach, sacrococcygeal approach, perineal approach, and combined approach. This study aims to evaluate the treatment efficacy of transparasacral approach for presacral tumors.Methods: 23 patients (7 males and 16 females) who are diagnosed with presacral tumors and receive surgery in transsacral approach at our department were chosen. The gender, age, body mass index (BMI), and clinical symptoms were recorded. The clinical data, postoperative complications, and short and long-term rehabilitation data were recorded and analyzed. Conclusions: The surgery was performed smoothly and the patients recovered well without signs of intestinal fistula, abdominal and pelvic infection, lung infection, organ dysfunction, or organ failure. The incision edema occurred in only one patient. In terms of the histopathological types, presacral tumors can be classified into tailgut cyst (n=10), epidermoid cyst (n=5), teratoma (n=3), and lipoma (n=10). One patient diagnosed with tailgut cyst was accompanied by adenocarcinoma transition. Tumor recurrence didn’t occur in any patients. In addition, no patients complained about dysuria, sacrococcygeal sensory disturbance, or sacrococcygeal and perineal discomfort. Surgical resection with transparasacral approach is effective for the treatment of presacral tumors with the advantages of high safety, good treatment efficacy, few complications, good oncological prognosis, and fast recovery.
