A clinical and surgical challenge: Retrorectal tumors.

AIMS: Retrorectal tumors are rare, mostly benign tumors and named due to their localization. Diagnoses of these tumors are usually delayed because of nonspecific complaints and symptoms. Magnetic resonance imaging has beneficial uses both for diagnosis and treatment. In this study, we reviewed a case series of retrorectal tumors.

SUBJECTS AND

METHODS

The patients who were diagnosed with retrorectal tumors between 2008 and 2015 were analyzed. This investigation was conducted at a Tertiary Education and Research Hospital. Sixteen patients were included in this study. Patients' demographic data, imaging workups, surgical operation reports, pathologic examination results, postoperative complications, and follow-up results were examined. Descriptive statistics, median, and standard deviation for continuous variables were used. The primary outcomes measured were diagnostic conflict, knowledge, and preference for surgery.

STATISTICAL ANALYSIS USED: Definitive statistical methods (mean, standard deviation, median, frequency, and percentage) were used to evaluate the study data.

RESULTS

One patient refused operation and one was in preoperative preparation period. Fourteen of sixteen patients were operated. Two (14.3%) of operated patients have malignant histopathological result (one gastrointestinal stromal tumor, one ganglioneuroblastoma). Rest of the operated patients' histopathological reports was as follows: Four schwannomas, three epidermoid cysts, two tailgut cyst, one dermoid cyst, one teratoma, and one angiomyolipoma. Eight patients were operated by posterior incision, five patients with transabdominal approach, and one patient with combined approach.

CONCLUSIONS

Retrorectal tumors are rare cases, and treatment of retrorectal tumors is surgery and should be operated in referenced hospitals to avoid diagnostic and therapeutic problems.
