Robot-Assisted Extended Pelvic Lymph Nodes Dissection for Prostate Cancer: Personal Surgical Technique and Outcomes

Objective: Extended pelvic lymph nodes dissection (EPLND) allows the removal of a higher number of lymph nodes than limited PLND. The aims of this study were to describe our robot-assisted EPLND (RAEPLND) technique with related complications, and to report the number of lymph nodes removed and the rate of lymph nodal metastasis. Materials and Methods: 153 patients underwent RAEPLND prior to robot-assisted radical prostatectomy (RARP). Indications were defined according to Briganti nomogram, to predict risk of lymph-nodal metastasis. Lymphatic packages covering the distal tract of the common iliac artery, the medial portion of the external iliac artery, the external iliac vein and the internal iliac vessels, together with the obturator and the presacral lymphatic packages were removed on both sides. Results: Median preoperative PSA was 7.5 ng/mL (IQR 5.5–11.5). Median operative time was 150 min (135–170). Median RAEPLND alone operative time was 38 min (32.75–41.25); for right and left side, 18 (15–29) and 20 min (15.75–30) (p=0.567). Median number of lymph nodes retrieved per patient was 25 (19.25–30); 13 (11–16) and 11 (8–15) for right and left side. In 19 patients (12.41%) metastasis was found at the level of pelvic lymph nodes. Median number of positive lymph nodes was 1 (1–4.6) per patient. Complications occurred in 11 patients (7.3%). Conclusions: the number of lymph nodes removed was comparable to published data about open series, allowing the increase of detection rate of lymph nodal metastasis for minimally invasive approach without compromising complications' rate if performing the procedure following reported technique.

Feasibility, complications and oncologic results of a limited inguinal lymph node dissection in the management of penile cancer

In patients with penile cancer (PeCa) and increased risk of inguinal lymphatic dissemination, inguinal lymphadenectomy offers a direct histological staging as the most reliable tool for assessment of the nodal metastasic status and a definitive oncologic treatment simultaneously. However, peri- and/or postoperative mutilating sequalae often occurn. We report on clinical outcome and complications of a limited inguinal lymph node (LN) dissection.

The use of enoxaparin to prevent venous thromboembolism in patients undergoing radical retropubic prostatectomy: feasibility and utility

OBJECTIVE: To assess the utility of enoxaparin in prevention of venous thromboembolism (VTE) in men poorly compliant with pneumatic compression stockings (PCS) in the immediate postoperative period after a radical retropubic prostatectomy (RP). MATERIALS AND METHODS: This retrospective study included 47 men who underwent RP at an inner-city tertiary care hospital. All patients were started on enoxaparin 40 mg subcutaneously 6-8 hours postoperatively and daily while hospitalized. Preoperative, operative, and postoperative data were collected and analyzed. Median follow-up was 18 months. RESULTS: Median patient age was 64 ± 7 years, median prostate-specific antigen level was 4.9 ng/mL and median prostate biopsy-determined Gleason score was 6. Forty-one men (87 percent) underwent a pelvic lymph node dissection. Median operative time was 181 minutes (range 164-450 minutes). Median estimated blood loss was 700 mL. Approximately 36 percent of the men wore PCS the recommended > 19 hours/day. On average PCS were worn 10.3 ± 7.5 hours/day. Postoperative complications were not increased in this cohort. Two patients developed pulmonary embolism requiring long-term anticoagulation. There were no mortalities. CONCLUSIONS: In men non-compliant with PCS, initiation of enoxaparin in the immediate postoperative setting was well-tolerated and maintained a low (4 percent) rate of VTE. Thus, enoxaparin may be useful in adjunct with PCS in these patients.
