A hybrid technique of lap perineal pelvic lymphadenectomy after open radical perineal prostatectomy in localized carcinoma prostate: Our initial experience.

OBJECTIVE

The major disadvantage of radical perineal prostatectomy (RPP) is the difficulty to perform pelvic lymphadenectomy via the same incision. Open retropubic, mini laparotomy, and transperitoneal laparoscopic pelvic lymphadenectomy as an adjunct to open RPP have been tried but need change in patient position and separate incision, thereby decreasing the acceptability of this procedure. Open RPP followed by a lap perineal pelvic lymphadenectomy via the same perineal incision is a hybrid technique that is aimed to decrease morbidity of lymphadenectomy.

MATERIAL AND METHODS

Patients of low and intermediate risk localized carcinoma prostate with a Partin score of >5% were taken for this procedure. After completing prostatectomy part of RPP, lap perineal pelvic lymphadenectomy was performed via same incision using single incision laparoscopic surgery port.

RESULTS

We performed this new hybrid technique in eight patients. Bilateral lymph node dissection required an additional mean time of 35 minutes. A total of 68 nodes were retrieved from eight patients with a median number of eight nodes (range: 6-12). None of our cases had any complications related to lymphadenectomy. Bilateral lymph node dissection was feasible in seven patients, and in one patient, it could be done on one side only.

CONCLUSION

Sandwiching lap perineal pelvic lymphadenectomy between prostatectomy part of RPP and urethra-vesical anastomosis (by open approach) is a safe, reproducible, and feasible approach to pelvic lymphadenectomy compared to lymphadenectomy from other routes with simultaneous reduction in the operative time, patient morbidity, and discomfort. Ease of doing lymphadenectomy from same incision can increase the acceptability of this excellent procedure.
