In a 25-year retrospective cohort study of patients undergoing surgery for retrorectal tumors at a tertiary center, researchers found excellent long-term outcomes, with a 5-year recurrence-free survival rate of 98% and only two recurrences observed during follow-up. Most tumors were benign and detected incidentally, and complete surgical resection was achieved in all patients. Postoperative complications were uncommon (7%) and managed nonoperatively. Although preoperative biopsy was performed in a minority of cases, it was associated with a higher—though not statistically significant—rate of complications, supporting a selective rather than routine approach to biopsy. Overall, the findings highlight the effectiveness of anatomy-based surgical planning and long-term surveillance in managing these rare tumors.
