Problems in diagnosis and treatment of retrorectal tumors: Our experience in 50 patients

Retrorectal tumors are rare lesions in adults,which remains a difficult diagnostic and management problem. the purpose of this study was to evaluate the results of surgical management of retrorectal tumors in our institution. in a retrospective study,a consecutive series of patients who underwent surgical excision of a retrorectal tumor were identified from a database. medical records,radiology,pathology reports and surgical approach were checked retrospectively. the data was analyzed using spss statistical software (version 18). from 50 patients,24 were male,and 26 were female with the mean age of 41.7 years. the origin of mass was congenital in 46% (23 cases) and neurogenic in 14% (7 patients),bone origin in 12% (6 cases) and miscellaneous in 24% (12 cases). in total,56.7% (21 cases) were malignant. surgical approaches included laparotomy in 11 cases,the sacral approach in 17 cases,the anterior-posterior approach in 14 cases and one case through abdomino-sacral approach. the mean follow-up was 56.7 (10-277) month. ten patients died due to extensive metastases with a mean survival of 46.6 (1-158) months. primary urethrorectal tumors are very rare. successful treatment of these tumors requires careful clinical evaluation and expertise in pelvic surgery. © 2016 tehran university of medical sciences. all rights reserved.
