Surgical strategies in the management of recurrent retrorectal tumours.

BACKGROUND

The aim of this study was to review a consecutive series of patients who had undergone excision of recurrent retrorectal tumours and propose surgical strategies to tackle such recurrences.

METHODS

Patients were identified from a prospectively maintained database. Demographic details, preoperative imaging and pathology, intra- and post-operative problems and follow-up details were noted.

RESULTS

Fifteen patients (11 females) with a median age of 38 years (range 19-75 years) underwent excision of recurrent retrorectal tumours (13 benign) between 2002 and 2012. The median interval between the first and second surgical procedure was 3.5 years (range 1-19 years). Three patients had surgery performed via the transperineal approach, while 12 patients had resection via the abdominal approach. En bloc resection of adjacent organs was needed in three patients. Major pelvic bleeding occurred in two patients. R0 resection was achieved in all 15 patients, and there have been no subsequent recurrences [median follow-up 73 months (range 12-148 months)].

CONCLUSIONS

Benign recurrent retrorectal tumours can be safely excised usually without sacrifice of adjacent organs, while en bloc resection is needed for malignant tumours.
