Laparoscopic radical prostatectomy: functional and oncological outcomes

Men's experiences following laparoscopic radical prostatectomy: a qualitative descriptive study

BACKGROUND

Laparoscopic radical prostatectomy is a less invasive surgical option to the open retropubic approach for prostate cancer that will likely grow in popularity commensurate with availability. However, since little is known about what men experience throughout the postoperative period, our ability to ensure informed decision-making remains compromised.

OBJECTIVES

The aim of this study was to explore what men experience following laparoscopic radical prostatectomy and how adequately their pre- and postoperative needs are being met.

DESIGN

This was a qualitative descriptive study.

PARTICIPANTS

Nineteen men, aged 46-76, who had undergone laparoscopic radical prostatectomy within the previous 3-6 months period were recruited from the treatment and control arms of a randomized controlled trial. Men who were not in the trial were recruited via letters mailed from surgeons' offices.

METHODS

Data were generated during loosely structured individual (n=5) and focus group interviews (n=3). Inductive content analysis helped to ensure that participants' perspectives were accurately represented.

RESULTS

Men had actively sought information prior to surgery but seemed unprepared for the intensity of discomfort and incontinence they experienced. They particularly valued opportunities for informal discussion with former prostatectomy patients; however, erectile dysfunction remained a major concern and most did not know where to turn for help.

CONCLUSION

Nurses could play a pivotal role in the laparoscopic radical prostatectomy experience by ensuring men are well informed both pre- and postoperatively. Facilitating contact with other men who have undergone laparoscopic radical prostatectomy (LRP) and initiating conversation about potential side-effects such as urinary incontinence and erectile dysfunction would be an important starting point. Particularly in light of early discharge and concerns regarding erectile dysfunction, additional follow-up seems warranted.

Oncological and functional results of open, robot-assisted and laparoscopic radical prostatectomy: does surgical approach and surgical experience matter?

The treatment of prostate cancer has undergone a fundamental change in the last decade. New surgical and nonsurgical minimal invasive methods have evolved. As the methodology of the different treatments is commonly known to urologists, this article focuses on oncological and functional outcome of open retropubic (ORP), trans- or extraperitoneal endoscopical (LRP), and robot-assisted radical prostatectomy (RALP), based on personal experience and review of the literature. A MEDLINE search was performed to review the literature on LRP and RALP between 1982 and 2007 with special emphasis on oncological and functional results, technical considerations, comparison of LRP and RALP to ORP, laparoscopic training, historical aspects, and cost-efficiency of the techniques. Based on diligent training and proctoring programs, a continuous dissemination of laparoscopic techniques takes place. There is a trend towards the extraperitoneal access in most of the minimal invasive programs at least in the European community. Mid-term outcomes of LRP and short-term outcomes of RALP achieved equivalence to open surgery with regards to complications, oncologic and functional results. Distinct advantages of LRP include less postoperative pain, lower transfusion rates, shorter convalescence, and better cosmetics. In contrast to RALP, LRP reaches cost-equivalence with open surgery in selected centers. LRP and RALP reproduce the short-term results of open surgery while providing the advantages of a minimal access. Video-assisted teaching improves the transfer of anatomical knowledge and technical knowhow, but the discussion about the longer learning curve for laparoscopy handling remains. The future will show if European centers adopt the use of robots comparable to the United States.

Endoscopic extraperitoneal radical prostatectomy: the University of Leipzig experience of 1,300 cases

We herein review our experience with endoscopic extraperitoneal radical prostatectomy (EERPE) as a first line therapy for localized prostate cancer. A series of 1,300 patients underwent EERPE ("wide excision", standard nervesparing technique (nsEERPE), or intrafascial nsEERPE). The mean age of the patients was 63.3 years. Preoperative PSA mean value was 10.1 ng/ml. A total of 415 patients had undergone previous surgical procedure in the lower abdomen (n = 336) and prior surgery of the prostate (n = 79), respectively. The EERPE was employed in all cases without any specific selection criteria. Mean operative time was 153 (50-320) min. including lymphadenectomy with no conversion to open surgery. Seven intraoperative, 91 early and 4 late complications occurred. The transfusion rate was 0.9%. Positive surgical margins were found in 83 patients with pT2 stage (9.8%) and in 154 patients in pT3 stage (34.3%). The mean catheterization time was 6.2 days. The 12 month follow up indicated continence rate of 91.9% and potency rates of 34% in the unilateral nerve sparing group and 69.8% in the bilateral group. In the intrafascial nsEERPE group potency rates were 33.3% (unilateral) and 79.1% (bilateral) after 12 months. Postoperative positive surgical margins rate were 6.1% for pT2 and 20% for pT3 and the complications rate 4%. The results of this large series of 1,300 patients are promising. The recently introduced intrafascial nsEERPE further ameliorates the outcome of the procedure.

Anatomical Landmarks of Radical Prostatecomy

INTRODUCTION

In the present study, we review current literature and based on our experience, we present the anatomical landmarks of open and laparoscopic/endoscopic radical prostatectomy.

METHODS

A thorough literature search was performed with the Medline database on the anatomy and the nomenclature of the structures surrounding the prostate gland. The correct handling of puboprostatic ligaments, external urethral sphincter, prostatic fascias and neurovascular bundle is necessary for avoiding malfunction of the urogenital system after radical prostatectomy.

RESULTS

When evaluating new prostatectomy techniques, we should always take into account both clinical and final oncological outcomes. The present review adds further knowledge to the existing "postprostatectomy anatomical hazard" debate. It emphasizes upon the role of the puboprostatic ligaments and the course of the external urethral sphincter for urinary continence. When performing an intrafascial nerve sparing prostatectomy most urologists tend to approach as close to the prostatic capsula as possible, even though there is no concurrence regarding the nomenclature of the surrounding fascias and the course of the actual neurovascular bundles. After completion of an intrafascial technique the specimen does not contain any periprostatic tissue and thus the detection of pT3a disease is not feasible. This especially becomes problematic if the tumour reaches the resection margin.

DISCUSSION

Nerve sparing open and laparoscopic radical prostatectomy should aim in maintaining sexual function, recuperating early continence after surgery, without hindering the final oncological outcome to the procedure. Despite the different approaches for radical prostatectomy the key for better results is the understanding of the anatomy of the bladder neck and the urethra.

[Laparoscopic extraperitoneal radical prostatectomy: changes in time and updated results]

Laparoscopic radical prostatectomy has been established and adopted by specialized urologic centers around the world as the primary approach to the surgical management of localized prostate cancer. Urologists are on a continuous search for development of technical modifications and refinements, to reduce morbidity and ameliorate clinical and quality of life outcome. In 2002 we have initially reported our technique and experience with the totally extraperitoneal endoscopic radical prostatectomy (EERPE). In the present review paper we present the evolution of the technique and the latest results.

Nerve-Sparing Endoscopic Extraperitoneal Radical Prostatectomy: University of Leipzig Technique

PURPOSE

To describe the various operative steps as well as the functional and oncologic results of nerve-sparing endoscopic extraperitoneal radical prostatectomy (nsEERP).

PATIENTS AND METHODS

One hundred twenty preoperatively potent patients have been treated with bilateral nsEERPE in our department. The average age of the patients was 60.3 years (range 41-74 years), and the mean prostate weight was 48.6 g (range 24-117 g).

RESULTS

The mean operative time was 136 minutes (range 75-210 minutes). No conversions to open surgery were necessary. The mean catheterization time was 5.7 days (range 4-20 days). Lymphadenectomy was performed in 26 patients. The pathologic stages were pT2 in 78 and pT3 in 42 patients. Positive margins were detected in 7.7% (N = 6) and 19% (N = 8) of the patients with pT2 and pT3 disease, respectively. Erections sufficient for intercourse were reported in interviews with 58 patients (48.3%) during the 6-month follow-up period. Follow-up of at least 1 year is deemed necessary to draw more definite conclusions about erectile function. One week postoperatively, 32 patients (26.7%) required a maximum of 1 pad, 59 patients (49.2%) 2 or 3 pads, and 29 patients (24.2%) more than 3 pads per day because of incontinence, whereas 3 and 6 months after the procedure, 98 (82%) and 106 (88%) of the patients required a maximum of 1 pad, respectively.

CONCLUSION

Our results demonstrate that nsEERPE can be performed with equal efficacy and preliminary results similar to those of standard open radical prostatectomy as well as transperitoneal laparoscopic prostatectomy while completely avoiding intraperitoneal complications.

Laparoskopische Beckenchirurgie

Laparoscopic radical prostatectomy has become an equivalent alternative to the open retropubic approach, offering the advantages of minimally invasive surgery. It is being applied increasingly in Germany and the rest of Europe. Whether the surgical robot da Vinci will be used for this procedure to the same extent as in the United States is unpredictable because of high investment and maintenance costs. Similarly, laparoscopic sacrocolpopexy has proven to be a viable option compared to open transabdominal or transvaginal surgery, showing a significant reduction in postoperative morbidity. The value of radical cystectomy is controversial despite proven feasability. On one hand, the technical difficulties of purely laparoscopic urinary diversion result in very long operating times, and in the case of the laparoscopically assisted creation of a neobladder, the advantage of this approach has to be questioned. On the other hand, a maximum rate of 30% of local recurrences and distant metastases indicates at least poor patient selection. In conclusion, this procedure should be limited to a few experienced centers.

Anatomic nerve-sparing laparoscopic radical prostatectomy: Comparison of retrograde and antegrade techniques

OBJECTIVES

To compare the anatomic retrograde and antegrade preservation of the neurovascular bundle (NVB) during laparoscopic radical prostatectomy.

METHODS

Anatomic studies were reviewed, focusing on the fascial layers surrounding the prostate and NVB and the terminology used as described by Walsh and colleagues. Important operative steps have been illustrated using video clips. For the retrograde technique, after incision of levator fascia, the NVBs were released from the apex before division of the urethra. Along the plane between the laterally incised Denonvilliers and perirectal fascia, the prostate was mobilized from the rectum. Isolated clipping of the seminal vesicle arteries was performed in an antegrade manner, followed by control of the lateral pedicles, and identification of the course of the NVB. For the antegrade technique, after dissection of the seminal vesicles, the levator fascia was incised to develop a lateral NVB groove. After bladder neck division and lateral pedicle ligation, the lateral NVB groove was used as a guide for antegrade preservation of the NVB. During anastomosis, the NVBs located at the 5-o'clock and 7-o'clock positions were avoided in both techniques.

RESULTS

A questionnaire-based potency rate of 67% and 76%, respectively, was reported after bilateral nerve sparing using retrograde and antegrade laparoscopic radical prostatectomy techniques.

CONCLUSIONS

Both techniques allowed replication of open surgical principles. The video magnification enabled excellent demonstration of the periprostatic anatomy. The principles of interfascial dissection of the NVB, use of task-specific instrumentation, and avoiding energy sources around the NVB may be more important than the actual nerve-preservation technique used.

Use of a validated quality of life questionnaire to assess sexual function following laparoscopic radical prostatectomy

Wide variations exist in the methods for evaluating potency following radical prostatectomy. We describe our technique of laparoscopic radical prostatectomy (LRP), present our methods for assessing the return of potency following LRP, and discuss the relevant literature. Sexual function was assessed pre- and postoperatively using the Expanded Prostate Cancer Index Composite questionnaire (EPIC). Sexual function subscale scores (SFSS) were reported as a percentage of preoperative baseline sexual function. The EPIC was also used for single-question assessment of successful intercourse. We also reviewed the literature on prospective health-related quality of life results following LRP and open radical retropubic prostatectomy. Only patients reporting preoperative intercourse were analyzed. Of these, 72 and 35% undergoing bilateral and unilateral nerve sparing (NS) reported postoperative intercourse at 12 months (P=0.01). Mean SFSS at 12 months was 61 and 57% of baseline after bilateral and unilateral NS, respectively (P=0.71). Following NS procedures, 74% of patients < or =58 years of age and 41% of patients >58 years of age reported successful intercourse at 12 months (P=0.015). Mean SFSS was 64 and 52% of baseline function (P=0.249) at 12 months for patients < or =58 and >58 years of age, respectively. In patients <58 years of age who underwent bilateral NS surgery, 82% reported intercourse at 12 months. In conclusion, return of sexual function following NS LRP in our experience is comparable to reports from centers of excellence in open prostatectomy. Standardizing data collection using validated quality of life instruments can provide both surgeon and patient with a realistic forecast of relative return to normal sexual function following prostatectomy.

Sexual dysfunction after pelvic surgery

Pelvic surgeries are among the most common causes of organic sexual dysfunction in men and women. The impact of nerve-sparing surgery on potency has been well documented in radical prostatectomy. However, its impact on potency needs to be evaluated in other pelvic surgeries. Sexual dysfunction is highly prevalent even after multiple technical advances in the field of oncological surgeries. The prevalence varies from 8 to 82%, depending on the type of pelvic surgery. In females, sexual dysfunction has not been evaluated adequately using validated questionnaires. However, in subspecialized circles, treatment for female sexual dysfunction is becoming routine. Currently, physicians have several options for the treatment of erectile dysfunction (ED) in men. Since the introduction of oral PDE-5 inhibitors, oral therapy has become the first-line treatment option for ED, irrespective of etiology. Currently available treatment options for the female sexual dysfunction include estrogens, androgens, phosphodiesterase inhibitors, and dopamine receptor antagonists. Initial reports regarding the role of early rehabilitation are encouraging and may become the part of routine practice in the management of ED after pelvic surgery. In this article, we summarize the sexual dysfunction following pelvic surgeries and their management.

Laparoscopic and Robotic Assisted Radical Prostatectomy – Critical Analysis of the Results

OBJECTIVE

To evaluate the role of laparoscopic radical prostatectomy (LRP) and robotic assisted radical prostatectomy (RLRP) based on personal experience and a review of the literature.

MATERIAL AND METHODS

Own experience at one European and one American LRP-center includes more than 2000 cases. We performed a MEDLINE search reviewing the literature on LRP and RLRP between 1992 and 2005 with special emphasis on historical aspects, technical considerations, comparison to open retropubic (RRP) and perineal radical prostatectomy (PRP), laparoscopic training, and the cost-efficiency of the techniques.

RESULTS

Based on sophisticated training programs a continuous dissemination of the technique took place. In the United States, this process was accelerated by the use of the daVinci-robot. There is a trend towards the extraperitoneal access. Mid-term outcomes of LRP achieved equivalence to open surgery with regards to complications, oncologic and functional results. Distinct advantages of LRP include less postoperative pain, lower rate of complications, shorter convalescence, and better cosmesis. In contrast to RLRP, LRP may reach cost-equivalence with open surgery (i.e. by reduction of OR-time, use of multi-usable instruments).

CONCLUSIONS

LRP reproduces the excellent results of open surgery providing the advantages of minimal access. Video-assisted teaching improves the transfer of anatomical knowledge and technical knowhow. In contrast the United States, the use of robots is likely to remain limited in Europe.

Functional outcomes and oncological efficacy of Vattikuti Institute prostatectomy with Veil of Aphrodite nerve-sparing: an analysis of 154 consecutive patients

OBJECTIVES

To report updated results, at 1 year of follow-up, of a modified nerve-sparing robotic radical prostatectomy that preserves the lateral prostatic fascia (Veil of Aphrodite).

PATIENTS AND METHODS

From January to December 2003, 154 consecutive men had a Vattikuti Institute prostatectomy with Veil of Aphrodite nerve-sparing by one surgeon. A prospective database recorded patient demographics, intraoperative, peri-operative, and pathological variables. Peri-operative complications were recorded using the Clavien classification. Patients had serum prostate-specific antigen (PSA) levels measured every 3 months and self-administered the International Prostate Symptom Score and Sexual Health Inventory for Male questionnaires before and at 1 year after surgery.

RESULTS

The men had a mean age of 57.4 years, a mean body mass index of 27.2 kg/m(2), and a mean PSA level before surgery of 5.11 ng/mL. The mean operative duration was 122 min. At 1 year, 96% of the men reported having had intercourse and 71% had recovered normal erectile function. One man had a Clavien grade II complication, 4.6% of men with organ-confined disease had positive surgical margins, and no patient had a PSA recurrence at 12 months; 97% of the men were continent at 1 year, and the median time to continence was 14 days.

CONCLUSION

Veil of Aphrodite nerve-sparing surgery provides better recovery of sexual function at 1 year than in contemporary series from centres of excellence, without compromising cancer control and urinary function.

Nerve Sparing Laparoscopic Radical Prostatectomy: Our Technique

PURPOSE

To describe our technique of nerve sparing laparoscopic radical prostatectomy (LRP). We present the oncological and functional results (potency and urinary continence).

MATERIAL AND METHODS

LRP has become standard at our institution based on experience with more than 2800 consecutive cases operated on between 1997 and 2005. From May 2003 to March 2005 a total of 677 LRP were performed, 425 consecutive patients candidates for a nerve sparing technique have been operated using the intrafascial approach. The challenge of our technique is to remove the prostate without any thermic and mechanic traumatism, avoiding dissection of outer layer. Oncological data were assessed by pathological examination and post-operative PSA level. Functional results were assessed with a self questionnaire.

RESULTS

By pathological stage, 2 pT2a specimens (7.4%), 7 pT2b specimens (21%), 44 pT2c specimens (24%), 63 pT3a specimens (43%), 11 pT3b specimens (46%) were found to have positive surgical margins (SMs). In 86 specimen (59%) positive SMs were focal inframillimetric. Median follow-up was 11 months (range 1-22). The continence rate (no leakage/no pad) was 95% at 6 months, confirmed at 12 months among 202 patients. For 137 patients, potency rate was 58.5% at 12 months.

CONCLUSION

Intrafascial LRP provides satisfactory results in regard to recovery of continence and sexual function. Long-term progression and survival outcome are necessary before this procedure should be offered as a replacement for interfascial nerve sparing technique.

Nerve Sparing Endoscopic Extraperitoneal Radical Prostatectomy– Effect of Puboprostatic Ligament Preservation on Early Continence and Positive Margins

INTRODUCTION

A technical modification of nerve sparing endoscopic extraperitoneal radical prostatectomy (nsEERPE) with preservation of the puboprostatic ligaments is presented and compared to a previous technique.

MATERIALS AND METHODS

nsEERPE was performed in 100 men with clinically localized adenocarcinoma of the prostate from March 2004 through February 2005. Patients were divided into two groups: Group A included patients in whom a standard nsEERPE was performed (n=50), and group B included patients in whom a puboprostatic ligament sparing nsEERPE was performed (n=50). The postoperative follow-up was 2 weeks and 3 months evaluating preliminary effects on early continence and positive margins.

RESULTS

The early return to continence at 2 weeks postoperatively was achieved by 6 patients (12%) in group A, and 12 patients (24%) in group B. Three months after the procedure 24 (48%) and 38 (76%) patients were continent, in groups A and B respectively. Clinical outcome (early continence) was significantly better for Group B patients, at 2 weeks (chi-square test, p=0.0019) and at 3 months (chi-square test, p=0.0347) following surgery. No cases of complete or severe incontinence (more than 5 pads/day) were observed at 3 months after surgery, in either groups. Groups A and B did not exhibit significant differences regarding their histological status. In group A, positive margins were detected in 6.5% and 26.3% of patients with pT2 and pT3, respectively. In group B, positive margins were found in 3.2% and 15.8% of patients with pT2 and pT3, respectively

CONCLUSION

We propose the use of puboprostatic ligament-sparing nsEERPE as an intriguing method to ascertain recuperation of early continence after nerve sparing procedures, without hindering the final oncological outcome.

Laparoscopic Radical Prostatectomy Using an Extraperitoneal Approach: Nordwest Hospital Technique and Initial Experience in 255 Cases

PURPOSE

We report on our modifications in technique and initial experience with 255 extraperitoneal laparoscopic radical prostatectomy (eLRP).

PATIENTS AND METHODS

Using significant surgical modifications, our laparoscopic method replicates the steps of the retropubic descending RP. We evaluated 255 consecutive patients who underwent an eLRP with pelvic lymph-node dissection.

RESULTS

The mean operative time was 136 minutes (range 84-266 minutes). Because of technical difficulty, the first three patients were converted to open surgery. One major complication, myocardial infarction, and one surgical reintervention in a case of secondary rectourethral fistula after open surgical repair of a laparoscopic rectal injury were observed. The blood transfusion rate was 1.2%. The pathologic stage was pT2a in 56 patients (22%), pT2b in 50 (20%), pT2c in 74 (29%), pT3a in 42 (16%), pT3b in 29 (11%), and pT4 in 3 (2%). Positive margins were found in 7% of patients (13/180) with pT2 tumors and 27% of patients (19/71) with pT3 tumors. The mean catheterization time was 7 days. The continence rates (no pads at all) at 3, 6, and 12 months were 73.7% (146/198), 89.6% (112/125), and 92.7% (38/41), respectively. After a nerve-sparing procedure, the total potency rates at 3 and 6 months were 37.5% (21/56) and 48.8% (21/43), respectively.

CONCLUSION

The eLRP seems to be safe with short-term oncologic and functional results at least as favorable as those of open radical prostatectomy and classical transperitoneal LRP. The operative times are shorter, and the complication rate appears to be lower.

Laparoscopic Radical Prostatectomy - the Experience of the German Laparoscopic Working Group

PURPOSE

To present the current status of laparoscopic radical prostatectomy (LRP) in Germany, Austria and Switzerland with respect to transferability, learning curve, and outcome.

MATERIAL AND METHODS

The data of 5824 patients who underwent LRP in 18 centers by 50 urologists from March 1999 to August 2004 were analyzed retrospectively. Three centers performed more than 500, and six more than 250 cases. A transperitoneal descending technique with was used in 2701, a transperitoneal ascending in 1234, an extraperitoneal descending in 1814, and an extraperitoneal ascending modification in 75 cases. Specimen showed pT2 in 3535, pT3a in 1555, pT3b in 623, and pT4 in 111 cases.

RESULTS

Mean operating time averaged 211 (131-292) minutes, with shorter duration of the extraperitoneal descending technique. Conversion to open surgery averaged 2.4 (0-14.1) %. Re-intervention rate amounted to 2.7 (0.3-7.7) %. Complication rate averaged 8.9 (1.8-10.8) % including bleeding (0.3-2.5%) and rectal lesion (1.5-2.5%). The rate of positive margins was 10.6 (3.2-18) % for pT2- and 32.7 (20-38.5) % for pT3a-tumors Continence after 12 months was 84.9 (72-94) %. Data about potency (7 centers) revealed 52.5 (35-67) % full erections following bilateral nerve preservation. 5 year-PSA recurrence rate (3 centers) was 8.6 (4-15.3) % for pT2-tumors and 17.5 (15-20.6) % for pT3a-stages.

CONCLUSIONS

The results confirm the efficacy of the training program with safe transfer of LRP (i.e. low complication rate), however including all known problems of a retrospective study.

ENDOSCOPIC EXTRAPERITONEAL RADICAL PROSTATECTOMY: ONCOLOGICAL AND FUNCTIONAL RESULTS AFTER 700 PROCEDURES

PURPOSE

We review our experience with endoscopic (totally) extraperitoneal radical prostatectomy (EERPE) as first line therapy for localized prostate cancer.

MATERIALS AND METHODS

A total of 700 consecutive patients underwent EERPE. Mean patient age was 63.4 years (range 42 to 77). Mean preoperative prostate specific antigen was 10.7 ng/ml (range 1.4 to 82). A total of 206 patients (29.4%) had a history of previous lower abdominal or pelvic surgery including inguinal hernioplasty with mesh placement and 43 patients (6.1%) had a history of prostatic intervention (transurethral resection of the prostate, high intensity focused ultrasound, Millin prostatectomy, radiotherapy). After preparation of the preperitoneal space the technique of EERPE duplicates the steps of classic open descending retropubic radical prostatectomy including a nerve sparing EERPE when indicated.

RESULTS

Mean operative time was 151 minutes (range 50 to 320). There was no conversion and the transfusion rate was 0.9% in 6. Four patients (0.6%) had intraoperative rectal injuries which were treated endoscopically with a 2-layer suture. A total of 14 patients (2%) required early and 3 patients (0.4%) required late postoperative reintervention. Pathological stage was pT2a in 89 patients (12.7%), pT2b in 54 (7.7%), pT2c in 245 (35%), pT3a in 229 (32.7%), pT3b in 79 (11.2%) and pT4 in 4 patients (0.6%). Positive surgical margins were found in 10.8% (42 of 388) of patients with a pT2 tumor and in 31.2% (96 of 308) of patients with a pT3 tumor. Pelvic lymph node dissection was performed in 266 patients (38%), of whom 14 (5.3%) were found to have lymph node involvement. Mean catheterization time was 6.2 days. Six months after surgery 83.8% of the patients were completely continent, 10.4% needed 1 to 2 pads daily and 5.8% of patients needed more than 2 pads daily. Of all patients who underwent nerve sparing procedures, 100 patients had a postoperative followup of 6 months. Of the 66 patients with the unilateral nerve sparing approach 8 (12.1%) had erections sufficient for intercourse and 16 of 34 patients (47.1%) with the bilateral nerve sparing procedure had erections sufficient for intercourse with or without the help of phosphodiesterase type 5 inhibitors.

CONCLUSIONS

The results of this series are promising. Perioperative morbidity is low, and short-term oncological and functional results are favorable. Although the followup is too short to draw definite conclusions, it is obvious that a nerve sparing approach in EERPE is feasible and reproducible. Our data demonstrate that EERPE can be performed with equal efficacy and results compared with laparoscopic transperitoneal radical prostatectomy, while providing the ease and safety of a totally extraperitoneal approach, completely avoiding intraperitoneal complications.

Laparoscopic Radical Prostatectomy: The Value of Intraoperative Frozen Sections

OBJECTIVE

To examine the clinical and pathological value of intraoperative frozen section (IFS) in patients undergoing laparoscopic radical prostatectomy (L-RPE) for clinically localized prostate cancer.

METHODS

The study includes 198 consecutive cases of L-RPE. After removal of the prostate, a 2-3mm circumferential specimen was obtained from the apical and bladder neck soft-tissue margin and submitted for IFS examination. In cases suspicious for capsular incision (n=57), IFS were taken from the neurovascular bundle/lateral pedicle.

RESULTS

The IFS diagnosis from the apical, bladder neck, and neurovascular bundle/lateral pedicle soft-tissue margins was adenocarcinoma in 12 (6%), 1 (0.5%), and 2 (1%) cases, respectively. Patient age, clinical stage, and mean specimen weight were not associated with cancer at the apical IFS. The accuracy, sensitivity, specificity, positive and negative predictive value of the apical IFS to predict cancer in the permanent section of the apical soft-tissue margin was 96%, 70%, 97%, 58%, and 98%, respectively. All the patients (n=15) with cancer at IFS had wide resections of additional tissue in the area of positive soft-tissue margin and all had no cancer in the additional resected tissue. Especially at the apex, IFS decreases the overall PSM status on surgical specimen by 5.1% (apical PSM from 8.6% to 3.5%).

CONCLUSION

Because of the low predictive value of IFS of bladder neck and neurovascular bundle/lateral pedicle their use is not recommended. IFS of the apex should be performed to reduce the PSM rate.

Comparison of training modalities for performing laparoscopic radical prostatectomy: experience with 1,000 patients

PURPOSE

We report a detailed analysis of different training modalities on the transferability of laparoscopic radical prostatectomy to generations of surgeons.

MATERIAL AND METHODS

The first generation surgeon with experience with 600 cases and the second generation surgeon with 150 were trained in open retropubic radical prostatectomy and laparoscopy, whereas the third generation surgeon with 150 cases was trained only laparoscopically. The fourth generation of surgeons with a total of 50 cases was trained in our fellowship program. We analyzed groups of 50 operations. The groups were comparable with respect to patient age, prostate weight and pathological tumor stage.

RESULTS

We observed a continual decrease in operative time between (322 to 247 minutes.) and within (332 to 196 minutes.) the analyzed groups. This result was also expressed in a decrease in the time required for anastomosis. A significant decrease was observed for the initial transfusion rate (4% to 10%). No difference was found in the complication rate (ie conversion in 8% to 0% of cases). Pathological outcomes (ie positive margins for pT2/pT3) were comparable in the first 3 surgeon groups (14.9%, 14.2% and 22%, respectively) and available functional results (followup greater than 2 years) did not reveal any influence of the learning curve. A learning curve was observed only for overall operative time and the time required for anastomosis but it was shown to be significantly shorter for the following generations.

CONCLUSIONS

Based on a specific training program the personal level of education has a minor impact on the results and reproducibility of the laparoscopic radical prostatectomy technique.

Prosthetic mesh hernioplasty during laparoscopic radical prostatectomy

OBJECTIVES

To evaluate the role of simultaneous laparoscopic mesh prosthetic hernioplasty during laparoscopic radical prostatectomy (LRP), because 5% to 10% of candidates for radical prostatectomy present with a detectable inguinal hernia at their preoperative physical examination. Moreover, data have suggested a greater incidence of inguinal hernia after open radical prostatectomy.

METHODS

During 1035 LRP procedures, 50 laparoscopic mesh prosthetic hernioplasty procedures were performed in 37 patients (3.6%) for 13 bilateral and 24 unilateral inguinal hernias. We compared the outcome of LRP with simultaneous laparoscopic inguinal hernioplasty (group 1) with that of 37 match-paired patients treated by LRP alone (group 2). Both groups were matched according to age, prostate-specific antigen level, prostate volume, pathologic stage, and Gleason score. Perioperative parameters (ie, operative time, analgesic requirements) and postoperative results were analyzed.

RESULTS

The patient age was 64.1 +/- 6.4 years versus 62.8 +/- 4.9 years old and had a body mass of 26.5 +/- 3.0 versus 27.4 +/- 3.2 kg/m2 in groups 1 and 2 (with and without laparoscopic hernioplasty), respectively. The mean operating time (221.9 versus 191.2 minutes, P = 0.011) and the total amount of narcotic analgesic requirements (26.8 mg versus 17.5 mg, P = 0.026) was significantly increased in the patients who underwent simultaneous laparoscopic inguinal hernia mesh repair. No statistically significant difference was found in the complication rate (4% versus 2%), median catheter time (7 days), and positive surgical margins (21.8%).

CONCLUSIONS

Simultaneous repair of inguinal hernia during LRP using prosthetic mesh is feasible without adverse effects on surgical and functional parameters. Neither the transperitoneal nor extraperitoneal approach is associated with an increase in complications or morbidity. However, an extraperitoneal access allows an easier repair without the refixation of the peritoneum.

Update on laparoscopic and robotic radical prostatectomy

PURPOSE OF REVIEW

Laparoscopic and robotic-assisted prostatectomy have been proposed as alternatives to traditional open retropubic prostatectomy. In this review, we update the more recent data concerning the results, technical trends and controversies regarding these novel, minimally invasive procedures.

RECENT FINDINGS

As a result of improved patient selection, a better understanding of surgical anatomy, and refinements in surgical techniques, traditional retropubic prostatectomy set the standards very high, leaving little room for improvement. In this review, the results of laparoscopic prostatectomy are compared with contemporary in addition to historical series. Besides the transperitoneal laparoscopic approach, which was almost exclusively used in the initial series, the introduction and development of the extraperitoneal laparoscopic approach meant a significant change in the surgical strategy of a number of teams worldwide. The relative merits of the transperitoneal and extraperitoneal approaches are discussed. Robotic radical prostatectomy is a promising technical innovation that allows us to overcome many of the inherent limitations of laparoscopic surgery. As a result of financial constraints, the experience has been limited to a few centres worldwide.

SUMMARY

Although long-term results are still lacking, novel minimally invasive techniques seem to fulfil the highest standards of radical prostatectomy in terms of early oncological cure, functional results and morbidity. A standardization of data collection and evaluation methodology will be indispensable for a better comparison of the different series.

THE EFFECT OF PREVIOUS TRANSPERITONEAL LAPAROSCOPIC INGUINAL HERNIORRHAPHY ON TRANSPERITONEAL LAPAROSCOPIC RADICAL PROSTATECTOMY

PURPOSE

Previous laparoscopic herniorrhaphy has been considered a contraindication to laparoscopic radical prostatectomy (LRP). In this study we analyzed the impact of previous laparoscopic or open inguinal hernia repair on the outcome of transperitoneal laparoscopic radical prostatectomy using the Heilbronn technique.

MATERIALS AND METHODS

In our database of 1,089 patients with LRP we identified 20 who underwent transperitoneal LRP and had a history of transperitoneal laparoscopic inguinal herniorrhaphy using prosthetic mesh (group 1). The outcome in that group was compared to that of 20 matched pair patients of a total of 95 in whom LRP was performed following open inguinal herniorrhaphy (group 2) and 20 matched pair patients of a total of 771 without previous surgery (group 3). Perioperative parameters (operative time, blood donation and complications) and postoperative results (duration and amount of analgesic treatment, catheterization and the continence rate) were analyzed.

RESULTS

According to the matched pair algorithm the 3 groups did not differ with respect to age (63.8, 66.2 and 63.0 years, p = 0.226), prostate volume (47.2, 43.3 and 47.7 gm, p = 0.501) or body mass index (26.1, 25.8 and 26.2 kg/m, respectively, p = 0.641). Ten pelvic lymphadenectomies and 8 nerve sparing (4 unilateral and 4 bilateral) procedures were performed per group. Ten and 12 patients in groups 1 and 2 had a history of bilateral herniorrhaphy, while previous unilateral herniorrhaphy was noted in the remaining 10 and 8, respectively. Mean operative time +/- SD (203.3 +/- 3.54, 196.7 +/- 43.7 and 214.7 +/- 37.7 minutes, p = 0.346) and mean catheterization time (8.1 +/- 2.8, 7.7 +/- 2.5 and 7.4 +/- 2.1 days, respectively, p = 0.684) did not differ significantly among the 3 groups. However, the mean amount of narcotic analgesic was significantly higher in group 1 compared with groups 2 and 3 (32.1 +/- 11.9, 21.8 +/- 11.9 and 19.5 +/- 10.1 mg, respectively, p = 0.002). Continence rates were similar in the groups at 88%, 87% and 92%, respectively, 1 year after surgery.

CONCLUSIONS

Previous laparoscopic inguinal herniorrhaphy using prosthetic mesh does not adversively affect the operative outcomes or functional results of LRP, while the total amount of narcotic analgesics was significantly higher, reflecting increased postoperative morbidity.

Transperitoneal laparoscopic radical prostatectomy: ascending technique

BACKGROUND AND PURPOSE

To demonstrate the operative steps of transperitoneal laparoscopic radical prostatectomy with the ascending approach (Heilbronn technique).

PATIENTS AND METHODS

The technique is based on our experience with more than 1000 cases of clinically localized prostate cancer from March 1999 to April 2004. The technical steps, instrumental requirements, patient data, complications, and reintervention rate were reviewed.

RESULTS

The principles of the technique include the routine use of a voice-controlled robot (AESOP) for the camera, exposure of the prostatic apex with 120 degree retracting forceps, free-hand suturing for Santorini plexus control, application of 5-mm clips during the nerve-sparing technique, control of the prostatic pedicles by 12-mm Hem-o-Lock clips, the bladder neck-sparing technique in patients with stage T1c and T2a tumors, and use of interrupted sutures for the urethrovesical anastomosis. A considerable improvement was observed when comparing the first 300 with the most recent 300 cases (mean operating time 280 v 208 minutes; conversion rate 2.7% v 0.3%; reintervention rate 3.7% v 1.0%).

CONCLUSIONS

Through our experience with more than 1000 cases, transperitoneal access for laparoscopic radical prostatectomy has proven to be feasible and transferable with results comparable to those of the original open approach. Besides the well-known advantages of minimally invasive surgery, the video endoscopic approach may offer further benefits in permitting optimization of the technique by video assessment.

Comparison of transperitoneal and extraperitoneal laparoscopic radical prostatectomy using match-pair analysis

PURPOSE

Based on the experience of 1000 cases of laparoscopic radical prostatectomy, we compared the operative parameters of transperitoneal and extraperitoneal approaches in match-paired patient groups.

PATIENTS AND METHODS

We reviewed the charts of 53 consecutive patients who underwent selectively extraperitoneal laparoscopic radical prostatectomy comparing it to 53 match-paired patients treated by transperitoneal laparoscopic radical prostatectomy. The patients were matched for age, PSA (ng/ml), prostate volume (g), pathologic stage, Gleason score, presence of pelvic lymph node dissection and type of nerve-sparing technique. Perioperative parameters (operating time, blood donation, complications) and postoperative results (duration and amount of analgesic treatment, catheterization time) as well as oncological (surgical margin status) and functional (continence rate) results were analyzed.

RESULTS

Patients were 62.9 +/- 5.5 versus 62.9 +/- 5.4 years old, had 27.5 +/- 3.5 kg/m2 versus 26.7 +/- 2.8 kg/m2 body mass indices in the extraperitoneal and transperitoneal groups, respectively. Preoperative mean PSA and prostate volume were 7.4 +/- 4.6 ng/ml and 41.8 +/- 16.3 g in the extraperitoneal, 7.6 +/- 3.8 ng/ml and 42.0 +/- 14.8 g in the transperitoneal group. Pathologic stages were T2a in 12 vs. 13, T2b in 21 vs. 20, T2c in 7 vs. 8, T3a in 11 vs. 10 and T3b in 2 vs. 2 patients for both groups. Overall 211.8 vs. 197.1 minutes mean operative time (p = 0.328) and 21.9 +/- 15.4 mg vs. 26.3 +/- 15.8 mg narcotic analgesic requirements (p = 0.111) did not differ significantly in both groups. However, mean operating time was significantly longer in the extraperitoneal group when performing pelvic lymphadenectomy (244.5 vs. 209.6 minutes, p = 0.017). There was no statistical difference of complication rate (4% vs. 2%) and median catheter time (7 vs. 7 days), positive surgical margins (22.6% vs. 20.7%) and 12 months continence (86.7% vs. 84.9%).

CONCLUSIONS

There was no significant difference between the extraperitoneal and transperitoneal approaches using the Heilbronn technique regarding all important parameters. In addition to the preference and experience of the individual surgeon, previous abdominal surgery, gross obesity and requirement of simultaneous inguinal hernia repair may be considered as selective indications for extraperitoneal laparoscopic radical prostatectomy.

Laparoscopic Radical Prostatectomy: Prospective Evaluation of the Learning Curve

OBJECTIVE

We prospectively evaluated the learning curve (LC) of laparoscopic radical prostatectomy (L-RPE) regarding the improvements in operative times (OT) and technical difficulty in one-operator-practice as it compares with open RPE.

METHODS

Over 18 months, 50 L-RPE were performed by an inexperienced surgeon in laparoscopy but skilled in open surgery. Difficulty scores were obtained at the completion of each L-RPE comparing L-RPE to open RPE. OT, estimated blood loss (EBL), length of stay, and catheterization time were also obtained.

RESULTS

In the ablative part of L-RPE the median difficulty score was significantly higher (p<0.001) for the first 10 cases, decreased dramatically by case 11 becoming equivalent (p=0.3) to open RPE and by case 31 the L-RPE becomes significantly easier than open RPE (p=0.002). The difficulty scores for the urethrovesical anastomosis performance is always uniformly higher for the whole patient series (p<0.001). Median OT decreased significantly from 293 minutes in the first 10 cases to 114 minutes in the last 10 cases (p<0.001). Catheterization time and length of hospitalization, decreased significantly with the progression of the LC. EBL remained stable throughout the patient cases. Obesity, prior surgery, and extension of the procedure (lymphadenectomy, nerve-sparing) significantly increased the OT.

CONCLUSION

Although the ablative part of L-RPE has a relatively short LC for a skilled open surgeon reflected by the rapid decrease in difficulty scores and OT by case 21, the performance of anastomosis shows a longer LC. Intensive training on anastomosis may be necessary to master this skill.

Prostatectomía radical laparoscópica. ¿Sólo en Centros de excelencia?

OBJECTIVES

To present and evaluate our experience and initial results in radical laparoscopic prostatectomy which we have been using for two and an half years in our General Hospital (covering a total population of 200.000 inhabitants).

MATERIAL AND METHODS

Between December 2002 and August 2005, were selected 26 patients for radical laparoscopic prostatectomy (25 transperitoneal and 1 extraperitoneal). Mean age was 62.3 +/- 5.3 years (range 52-69). Mean PSA level was 9.16 +/- 4.20 ng/mL (range 5.26 to 24.3). Pre-operative classification was Tlc in 10 patients (38.4%), T2a in 8 (30.8%) and T2b in 8. Mean Gleason Score was 6 +/- 0.8 (range 4-7). Three patients had undergone preoperatively neo-adjuvant hormonal blockage (11.5%). Simultaneous bilateral inguinal lymphadenectomy was performed in two patients. In no case did we consider a nerve sparing approach.

RESULTS

The procedure was accomplished in 20 patients. Mean follow-up was 12.4 +/- 8.6 months (range 3 - 34). There was no perioperative mortality. Conversion to open surgery was required six times in the ten first cases but not thereafter. Mean operating time for the whole series was 303 +/- 95 minutes (range 150-540) but with a distinct difference between the first fourteen and the last six cases: 332 +/- 92.58 versus 236.6 +/- 66.5 (p<0.02). Mean blood loss was 90.25 +/- 46.5 ml. There were early postoperative complications in 4 patients (15.38%). Final pathological staging was: T2a in three patients (15%), T2b (50%) in 10, T3a (15%) in three and T3b (20%) in four. Positive margins were found in three cases (11.5%): T2b, T3a and T3b. Mean hospitalisation time was 4.7 +/- 3.1 days. Provided there was no urinary leakage, the urinary catheter was removed at 12.7 +/- 2.7 days. Full continence at three months was achieved in 17 of the patients (85%) who had undergone the full laparoscopic procedure.

CONCLUSIONS

Our previous experience in other major laparoscopic procedures has allowed us to perform radical laparoscopic prostatectomy with a fast learning curve even in a setting of a relatively low population. Initial long term results seem similar to those achieved with conventional surgery.

Comparison of Early Oncologic Results of Laparoscopic Radical Prostatectomy by Extraperitoneal versus Transperitoneal Approach

PURPOSE

Compare the early oncological results of laparoscopic radical prostatectomy performed by either an extraperitoneal or a transperitoneal approach.

METHODS

330 consecutive men underwent laparoscopic radical prostatectomy for localized prostate cancer, the first 165 by transperitoneal approach, and the last 165 by extraperitoneal approach. Clinical stage, serum PSA, Gleason score of biopsy were recorded, as well as operating time, surgical and medical complications, blood loss, length of hospital stay and catheterization time. The weight of the specimen, pathological stage (1997 TNM classification) and status of the surgical margins were noted. The Fisher test as well as the chi2-test were used for statistical analysis. Differences were considered significant when p < 0.05.

RESULTS

There were no significant differences between the two groups in terms of preoperative characteristics except for Gleason score of the biopsies which was higher in the extraperitoneal group (p < 0.0001). The operating time was longer with the transperitoneal approach (248.5 min vs. 220.0 min, p < 0.0001). There was no difference in transfusion rate (1.2% vs. 5.4%, transperitoneal vs. extraperitoneal, respectively, p = 0.6). There was no difference in hospital stay, medical and surgical complications. Respectively, in the transperitoneal and extraperitoneal groups, there were 108 and 88 pT2 tumors. There were no differences in terms of positive surgical margins between the two groups, 23% and 29.7% (p = 0.21) overall, 13.0% and 17.0% (p = 0.42) in pT2 tumors and 43.6% and 44.7% (p = 0.99) in pT3 tumors.

CONCLUSIONS

Extraperitoneal approach offers the same early oncological results as transperitoneal approach with a shorter operative time.
