Background
Surgical approaches for retrorectal tumors (RRT) are either abdominal, dorsal trans-sacrococcygeal, or perineal. Very few cases have been reported so far concerning a laparoscopic approach. The aim of this study was to assess the results of laparoscopy for the treatment of RRT.
Methods
All patients who underwent laparoscopy for RRT between 2003 and 2012 were reviewed. Data included patient and tumor characteristics, surgical morbidity, and mortality.
Results
A total of 12 consecutive women with a median age of 55 years underwent laparoscopy for RRT. Median operative time was 145 min (range 70–215). Two conversions in laparotomy occurred, and one patient needed a temporary diverting ileostomy for rectal injury. Postoperatively, two patients presented urinary tract infections. Median length of stay was 8 days (range 4–16). Pathological examinations showed complete resections (R0) for ten benign tumors and one malignant tumor (Ewing sarcoma). One lesion was incompletely resected, a colloid sarcoma (R1 status), and was re-operated on by laparotomy after neoadjuvant chemoradiation. No local recurrence was observed after a median follow-up of 34 months (range 12–79) for benign lesions, and 28 and 71 months for the two patients who underwent resection of Ewing and colloid sarcoma, respectively.
Conclusions
Laparoscopic resection for RRT seems feasible and safe. It allows complete excision of tumors located in the retrorectal space with low morbidity. Thus, this approach can be a valid alternative to standard Kraske or open abdominal approaches for the treatment of RRT.
