Introduction: Laparoscopic or robotic-assisted laparoscopic radical prostatectomy (RALP) is a frequently used approach for localized carcinoma prostate. For intermediate and high-risk cancers, extended pelvic lymph node dissection (e-PLND), is often performed. Conventional e-PLND involves piecemeal retrieval of lymphatic tissue. We describe a novel technique of laparoscopic e-PLND, which involves en-masse removal of pelvic lymph nodes from each side, based on an overlying peritoneal scaffold. Materials and Methods: Fifteen cases of intermediate and high-risk carcinoma prostate underwent laparoscopic radical prostatectomy (LRP) with peritoneal scaffold based e-PLND within a period of 1 year. We describe the surgical techqniue and outcomes in terms of operative time and lymph nodes retrieved. Results: The mean operating times for "peritoneal scaffold" lymphatic dissection was 48 min (38-64). The total number of lymph nodes retrieved was 18 (14-22). There were no cases with postoperative lymph collection or hematoma. Conclusion: The "peritoneal scaffold" technique of e-PLND is a novel technique, which involves having a peritoneal scaffold to bind and hold all the lymphatic tissues together in its anatomical orientation during dissection. This enables complete retrieval of specimen during LRP and RALP.
