Retrorectal Surgery Linked to Low Recurrence

A 25-year tertiary center cohort reports high recurrence-free survival following surgery and suggests preoperative biopsy should be used selectively.

Objective:

To evaluate long-term surgical outcomes and the clinical implications of preoperative biopsy in patients undergoing retrorectal tumor resection from 2000 to 2025.

Approach:

Key Findings:

5-year recurrence-free survival rate of 98%.
Local recurrence rate of 3%.
Complete resection achieved in all patients.
Postoperative complications occurred in 7% of patients.
95% of tumors were benign.
12% of patients underwent preoperative biopsy.

Interpretation:

Preoperative biopsy is not routinely recommended due to potential complications and limited diagnostic yield; imaging often provides sufficient information for surgical planning.

Limitations:

Single-center design.
Small number of recurrence and complication events limiting multivariate analysis.

Conclusion:

Surgical resection of retrorectal tumors is associated with low recurrence rates and manageable complications; selective use of preoperative biopsy is advised.
