Abstract
PURPOSE This study investigated the effects of ice cream consumption on chyle leakage after left lateral neck dissection in patients with thyroid cancer. METHODS A total of 491 patients with thyroid cancer underwent left lateral neck dissection with identification of the thoracic duct following ice cream consumption. Before closing the wound, the anesthesiologist increased the intrathoracic pressure to observe chyle leakage. If chyle leakage occurred postoperatively, the drain was removed using the drain negative pressure release test. RESULTS Postoperative chyle leakage was observed in 18 of the 491 patients who underwent left lateral neck dissection. We treated 17 patients conservatively and 1 patient surgically. Drains were removed within five days in all patients. After the drain negative pressure release test had been performed in eight patients, the drainage volume significantly decreased from an average of 175 ml to 31 ml per day. The average number of days until the removal of the drainage tube was 3.2 days. No perioperative complications were associated with ice cream consumption. CONCLUSIONS In left lateral neck dissection for thyroid cancer, performing surgery following ice cream consumption does not completely prevent chyle leakage; however, early drain removal is possible because there is only mild leakage.

Peritoneal flap for lymphocele prophylaxis following robotic-assisted laparoscopic radical prostatectomy with pelvic lymph node dissection: study protocol and trial update for the randomized controlled PELYCAN study. Trials 2021; 22:236. [PMID: 33781339 PMCID: PMC8008541 DOI: 10.1186/s13063-021-05168-x] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2020] [Accepted: 03/02/2021] [Indexed: 11/17/2022] Open
Abstract
Background Data from interventional studies suggest that a peritoneal flap after pelvic lymph node dissection (LND) during laparoscopic, robotic-assisted radical prostatectomy (RARP) may reduce the rate of symptomatic lymphoceles in transperitoneal approach. However, most of these studies are not conducted in a randomized controlled fashion, thus limiting their scientific value. A recent prospective, randomized, controlled trial (RCT) did not show superiority of a peritoneal flap while further trials are lacking. Therefore, the aim of the presented RCT will be to show that creating a peritoneal flap decreases the rate of symptomatic lymphoceles compared to the current standard procedure without creation of a flap. Methods/design PELYCAN is a parallel-group, patient- and assessor-blinded, phase III, adaptive randomized controlled superiority trial. Men with histologically confirmed prostate cancer who undergo transperitoneal RARP with pelvic LND will be randomly assigned in a 1:1 ratio to two groups—either with creating a peritoneal flap (PELYCAN) or without creating a peritoneal flap (control). Sample size calculation yielded a sample size of 300 with a planned interim analysis after 120 patients, which will be performed by an independent statistician. This provides a possibility for early stopping or sample size recalculation. Patients will be stratified for contributing factors for the development of postoperative lymphoceles. The primary outcome measure will be the rate of symptomatic lymphoceles in both groups within 6 months postoperatively. Patients and assessors will be blinded for the intervention until the end of the follow-up period of 6 months. The surgeon will be informed about the randomization result after performance of vesicourethral anastomosis. Secondary outcome measures include asymptomatic lymphoceles at the time of discharge and within 6 months of follow-up, postoperative complications, mortality, re-admission rate, and quality of life assessed by the EORTC QLQ-C30 questionnaire. Discussion The PELYCAN study is designed to assess whether the application of a peritoneal flap during RARP reduces the rate of symptomatic lymphoceles, as compared with the standard operation technique. In case of superiority of the intervention, this peritoneal flap may be suggested as a new standard of care. Trial registration German Clinical Trials Register DRKS00016794.

Abstract
Pelvic lymph node dissection (PLND) is an important component in the staging and prognostication of prostate cancer. We performed a narrative review to assess the literature surrounding PLND: (I) the current guideline recommendations and contemporary utilization, (II) the calculation of patient-specific risk to perform PLND using available nomograms, (III) to review the extent of dissection, and its associated outcomes and complications. Due to the improved lymph node yield, better staging, and theoretical improvement in the control of micro-metastatic disease, guidelines have supported the use of (extended-) PLND in patients deemed to be at intermediate or high risk of lymph node involvement (often at a threshold of 5% on modern risk nomograms). However, in practice, real-world utilization of PLND varies considerably due to multiple reasons. Conflicting evidence persists with no clear oncological benefit to PLND, and a small, but important, risk of morbidity. Complications are rare, but include lymphoceles; thromboembolic events; and more rarely, obturator nerve, vascular, and ureteric injury. Furthermore, changing disease incidence and stage migration in the context of earlier detection overall have led to a decreased risk of nodal disease. The trade-offs between the benefits, harms, and risk tolerance/threshold must be carefully considered between each patient and their clinician.

Abstract
OBJECTIVE To determine an accurate incidence of lymphocele formation and its sequela after robot-assisted radical prostatectomy (RARP) and extended lymph node dissection (eLND) in a contemporary prostate cancer cohort. PATIENTS AND METHOD Consecutive patients who underwent RARP and eLND and had a minimum follow-up of 3 months were included. All surgeries were performed by one surgeon via a transperitoneal approach, with patients uniformly receiving low-molecular-weight heparin. Patients were followed with serial ultrasonography (US) based on a predetermined schedule for lymphocele surveillance. Incidence and sequelae of lymphoceles were retrospectively assessed. RESULTS In all, 521 patients were analysed. The mean (sd) follow-up was 33.5 (22.8) months. Lymphocele developed in 9% and became symptomatic in 2.5%. All except one were detected at the 1-month postoperative US; however, 76% regressed by the 3-month US. If lymphocele persisted at 3 months, 64% developed symptoms associated with infection and required drainage. Having diabetes mellitus was significantly associated with a higher risk of developing an infected lymphocele. Other symptoms related to lymphocele were rare. Comparisons of patient characteristics between patients with and without lymphoceles did not show any significant prognostic indicators to predict the occurrence of lymphocele in neither univariate nor multivariate analysis in the present cohort. CONCLUSION The incidence of symptomatic lymphocele after transperitoneal RARP and eLND is rare. However, during follow-up, US imaging at 3 months after surgery appears advisable. If a lymphocele is detected at the 3-month follow-up US discussing percutaneous external drainage with the patient appears to be wise, as it may prevent the development of a symptomatic lymphocele in two-thirds of such patients.

Abstract
Pelvic lymphocele is a potential complication of radical prostatectomy. Although lymphoceles often regress spontaneously, many may progress, precipitate clinical symptoms, and ultimately require intervention. To date, the best treatment of pelvic lymphoceles has not yet been fully defined. However, laparoscopic marsupialization is a definitive and efficacious surgical alternative to percutaneous drainage. It is effective, results in minimal patient morbidity, and allows for rapid recovery. We report our experience with management of clinically symptomatic pelvic lymphoceles following robotic-assisted prostatectomy using laparoscopic marsupialization.

Abstract
BACKGROUND Pelvic lymphoceles (LCs) following radical prostatectomy (LC-RPs) are a well-described complication. Symptomatic LC-RPs are the most frequent, nonfunctional, postradical prostatectomy complications. OBJECTIVES Description of the clinical presentations of LC-RPs and the detailed technique of laparoscopic pelvic LC marsupialisation (LM), including perioperative results and follow-up. DESIGN, SETTING, AND PARTICIPANTS Data from 105 patients (age range: 57-76 yr) with symptomatic LC-RPs who underwent surgery in our institute were evaluated retrospectively. Pelvic ultrasound (US) and computed tomography scans, performed on all patients, revealed LC volumes ranging from 100 to 1200 ml. Fifty-five patients were refractory to prior percutaneous tube drainage and/or sclerotherapy. LM was performed using a three-trocar (n=60 patients) or two-trocar technique (n=45 patients). SURGICAL PROCEDURE With the patient in Trendelenburg position, LCs were accurately identified by inspection, compressibility, and/or laparoscopic needle aspiration. A Foley catheter was inserted. Through one or two working trocars in the left lower abdomen, an adequate peritoneal window (wide ellipse) was excised. The LC cavity was inspected and septae, membranes, and haematomas were removed. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Perioperative surgical outcomes, analgesic medication, and inflammation parameters were recorded. Follow-up and success rates were estimated with US for LC recurrence. RESULTS AND LIMITATIONS Five pelvic LC locations could be identified: paravesical, lateral pelvic (encapsulated and uncapsulated), prevesical, and with retroperitoneal extension. These were relevant for clinical diagnosis and management options. Pelvic LCs were right-sided in 37 patients, left-sided in 15, and on both sides in 53. All LM were uneventful and operating time (mean) ranged from 15 to 265 (31.7) min, which became shorter with increasing experience. One conversion with postoperative blood transfusion was necessary. Patients were discharged between 2 and 4 (mean: 2.3) d postoperatively. Postoperative US revealed primary success in all cases. Three patients developed recurrence from 1 to 3 wk posthospitalisation; otherwise, none had treatment for LC during a mean follow-up of 20 mo. Limitations include the retrospective study design and the small number of patients. CONCLUSIONS LC-RPs are common and can be classified into five different patterns of clinical/anatomic presentation. LM is simple, feasible, and safe as the first-line treatment for large, noninfected, symptomatic or refractory LC-RPs with fewer complications and an overall 97% success rate.

Abstract
AIM To compare the clinical outcomes and associated costs between laparoscopic and abdominal surgery for patients with endometrioid endometrial cancer. METHODS From 2003 to 2008, 115 patients who underwent laparoscopically-assisted surgery for endometrioid endometrial cancers were enrolled in this retrospective study. Another 123 patients who had abdominal surgery for the same histological type of endometrial cancer were included as the control group. The clinico-pathological variables, surgical outcome, costs, death and case recurrence of the two groups were compared. RESULTS There was no difference in the patients' age, body mass index, FIGO stage, histological grade or surgical types between the two groups. The patients in the laparoscopy group had less blood loss (P = 0.010), a shorter hospital stay (P < 0.001), less postoperative pain (P < 0.001) and lower complication rates (P < 0.001) than those treated by laparotomy. The total costs in the laparoscopy group were higher than that in the laparotomy group ($2073 vs $1638, P < 0.001). Patients in the laparoscopy group returned to usual activity more quickly (P = 0.001) and went back to work earlier (P = 0.013) than those in laparotomy group. With a median follow-up of 42 months for the laparoscopy group and 40 months for the laparotomy group, there was no significant difference in the number of cases with respect to death (P = 1.000) or recurrence (P = 1.000). CONCLUSIONS Laparoscopically-assisted surgery is as effective as the laparotomy approach for the treatment of early-stage and advanced-stage endometrial cancer. The relatively higher cost of the laparoscopic surgery may be compensated by its benefits. In developing countries such as China, laparoscopically-assisted surgery is also an attractive alternative for selected patients with endometrial cancer.

Abstract
Pelvic lymphocele is a postoperative complications than can result after endoscopic extraperitoneal radical prostatectomy and pelvic lymph node dissection. Radical prostatectomy have many risk factors of deep vein thrombosis including location of target organ, malignancy, old age, Trendelenburg position, pelvic lymph node dissection, and long procedure time. A 57-year-old man with a localized prostate cancer was treated with endoscopic extraperitoneal radical prostatectomy and pelvic lymph node dissection. Deep vein thrombosis was detected as a first sign of pelvic lymphocele. Lymphocele was managed with a percutaneous drainage without sclerosant. We report a case of deep vein thrombosis due to pelvic lymphocele after endoscopic extraperitoneal radical prostatectomy.

Abstract
OBJECTIVE • To determine the incidence and predictive factors of lymphocele formation in patients undergoing pelvic lymph node dissection (PLND) during robot-assisted radical prostatectomy (RARP). PATIENTS AND METHODS • Between April and December 2008, 76 patients underwent PLND during RARP for ≥cT2c, prostate-specific antigen level ≥10, Gleason score ≥7 prostate cancer. • All patients were prospectively followed up with pelvic computed tomography 6-12 weeks after the procedure. • All patients received s.c. heparin preoperatively and postoperatively. PLND was limited to zones 1 and 2 as defined by Studer. • Plasma-kinetic bipolar forceps were used for haemostasis during PLND. RESULTS • At a mean follow-up of 10.8 weeks, 51% (39/76) of patients had developed a lymphocele. Of these 39 lymphoceles 32 (82%) were unilateral and seven (18%) were bilateral. • The mean (range) lymphocele size was 4.3 × 3.2 (1.5-12.3) cm; 41% of lymphoceles were <4 cm, 53.9% were 4-10 cm, and 5.1% were >10 cm in diameter. Six of the 39 lymphoceles (15.4%) were clinically symptomatic. The symptoms were as follows: pelvic pressure in five patients, abdominal distension with ileus in three patients, leg pain/weakness in one patient and costovertebral tenderness in one patient. Two lymphoceles required intervention. • On the logistic regression model the presence of nodal metastases, tumour volume in the prostate specimen and extracapsular extension (ECE) were independent risk factors for the development of a lymphocele. • There was no correlation between estimated blood loss, body mass index, pathological Gleason score or number nodes dissected and the presence of lymphocele. CONCLUSIONS • The incidence of lymphoceles was higher than anticipated given the believed protective effect of the transperitoneal approach against lymphocele formation. • The risk of lymphocele seemed to increase linearly with the presence of more extensive disease, particularly ECE and nodal involvement. • The benefit of PLND during RARP should be weighed against the elevated risk of lymphocele formation and its potential complications.

Abstract
PURPOSE Our goal was to assess outcomes of a selective drain placement strategy during laparoscopic radical prostatectomy (LRP) with a running urethrovesical anastomosis (RUVA) using cystographic imaging in all patients. MATERIALS AND METHODS A retrospective chart review was performed for all patients undergoing LRP between January 2003 and December 2004. The anastomosis was performed using a modified van Velthoven technique. A drain was placed at the discretion of the senior surgeon when a urinary leak was demonstrated with bladder irrigation, clinical suspicion for a urinary leak was high, or a complex bladder neck reconstruction was performed. Routine postoperative cystograms were obtained. RESULTS 208 patients underwent LRP with a RUVA. Data including cystogram was available for 206 patients. The overall rate of cystographic urine leak was 5.8%. A drain was placed in 51 patients. Of these, 8 (15.6%) had a postoperative leak on cystogram. Of the 157 undrained patients, urine leak was radiographically visible in 4 (2.5%). The higher leak rate in the drained vs. undrained cohort was statistically significant (p = 0.002). Twenty-four patients underwent pelvic lymph node dissection (8 drained, 16 undrained). Three undrained patients developed lymphoceles, which presented clinically on average 3 weeks postoperatively. There were no urinomas or hematomas in either group. CONCLUSIONS Routine placement of a pelvic drain after LRP with a RUVA is not necessary, unless the anastomotic integrity is suboptimal intraoperatively. Experienced clinical judgment is essential and accurate in identifying patients at risk for postoperative leakage. When suspicion is low, omitting a drain does not increase morbidity.

Abstract
PURPOSE Sealing the lymphatic vessels during abdominal and pelvic surgery is important to prevent the leakage of lymphatic fluid and its resultant sequelae. To our knowledge we compared for the first time the quality of lymphatic sealing by each of 4 commonly used laparoscopic dissection devices. MATERIALS AND METHODS A total of 12 domestic pigs were used to test dissecting devices, including monopolar scissors (Ethicon Endo-Surgery, Cincinnati, Ohio), Harmonic ACE Scalpel, LigaSure V, EnSeal and Trissector. A midline incision was made from mid sternum to umbilicus, the diaphragm was divided and the porcine thoracic duct was isolated. In all animals each device was used to seal an area of the duct and each seal was placed at least 2 cm from the prior seal. In group 1 the thoracic duct of 6 pigs was cannulated with a 5Fr catheter and the seal was subjected to burst pressure testing using a burst pressure measuring device (Cole-Parmer, Vernon Hills, Illinois). In the 6 pigs in group 2 each seal was immediately sent for histopathological evaluation. Specimens were given a score for the extent of cautery damage, including 0-none, 1-minimal, 2-moderate, 3-severe and 4-extreme. RESULTS A total of 64 seals were created, of which 35 were subjected to burst pressure testing. Mean size of the thoracic duct was 2.6 mm. No acute seal failures were observed with any bipolar device or the harmonic shears. However, 2 immediate failures (33%) were seen with monopolar scissors. Mean burst pressure for monopolar scissors, Harmonic ACE Scalpel, LigaSure V, EnSeal and Trissector was 46 (range 0 to 165), 540 (range 175 to 795), 258 (range 75 to 435), 453 (range 255 to 825) and 379 mm Hg (range 175 to 605), respectively (p <0.05). Trissector, Harmonic ACE Scalpel and EnSeal generated seals with significantly higher burst pressure than that of monopolar scissors (p <0.05). Histopathological evaluation revealed that LigaSure caused less thermal damage than Trissector and EnSeal (p <0.05). CONCLUSIONS Each device tested except monopolar scissors consistently produced a supraphysiological seal and should be suitable for sealing lymphatic vessels during laparoscopic surgery.

Abstract
BACKGROUND Lymphoceles are frequent complications of pelvic lymph node dissection. While small lymphoceles often remain undetected, larger ones can cause complications and require further treatment, e.g. percutaneous tube drainage alone or in combination with sclerotherapy. However, recurrence rates are considerable, and long-lasting drainage may lead to infection, prolonged hospitalization, and as a consequence, increased overall costs. We report the results of a simplified laparoscopic approach to drain lymphoceles after radical prostatectomy plus pelvic lymphadenectomy using methylene blue instillation. METHODS 13 patients with large symptomatic pelvic/retroperitoneal lymphoceles refractory to percutaneous tube drainage and doxycycline sclerotherapy received a laparoscopic transperitoneal marsupialization following instillation of a sterile diluted methylene blue solution into the drained cavity to refill and mark the lymphocele. RESULTS All lymphoceles were sterile and ranged in size from 7 x 6 x 4 to 15 x 12 x 6 cm. Clinical symptoms included lower abdominal swelling, tenderness in the iliac fossa, ipsilateral lymphedema, deep venous thrombosis, wound fistula, and hydronephrosis due to ureteral obstruction. After methylene blue instillation, the lymphoceles were easily identified and opened. Median total operative time was 50 (range 25-70) min; blood loss was negligible. There was one complication in the form of a metachronous infection in the operating field and no relapses. Patients were discharged 1-5 (median 3) days after the surgical procedure. CONCLUSIONS Laparoscopic peritoneal drainage requires greater operative skill than percutaneous approaches. However, the instillation of a methylene blue solution simplifies this procedure as the extent and location of the lymphoceles can be precisely identified during laparoscopy. We recommend early application of laparoscopic peritoneal drainage following methylene blue instillation for patients with sterile lymphoceles after pelvic lymph node dissection in whom temporary percutaneous drainage and sclerotherapy failed to resolve the lymph fluid collection.

Abstract
Pelvic lymphocele, also known as lymphocyst, is a cystic structure caused by lymphatic injury usually secondary to pelvic lymphadenectomy and renal transplantation. Lymphoceles can cause morbidity and rarely mortality by compression of adjacent structures and infectious complications. This review discusses etiology and treatment options for pelvic lymphoceles including surgical and percutaneous methods with emphasis on percutaneous techniques particularly in conjunction with sclerotherapy. Percutaneous catheter drainage with sclerotherapy procedure with various sclerosing agents is described in detail. Ethanol, povidone-iodine, tetracycline, doxycycline, bleomycin, talc and fibrin glue can be used as sclerosing agents. Combination of sclerosing agents to percutaneous catheter drainage significantly improves success rate in the treatment of pelvic lymphoceles. Infected lymphoceles are usually treated solely with percutaneous catheter drainage. Percutaneous treatment can be tailored according to volume of lymphoceles. We generally prefer single session sclerotherapy and 1 day catheter drainage in lymphoceles less than 150 mL, and larger ones are treated by multi-session sclerotherapy until daily drainage decreases below 10 mL. Percutaneous treatment preferably with sclerotherapy should be considered as the first-line treatment modality for pelvic lymphoceles due to its effectiveness, widespread applicability on an outpatient basis, ease of procedure and low complication rate.

Abstract
OBJECTIVE To evaluate the feasibility, safety and utility of the ultrasonic shears for laparoscopic pelvic and para-aortic lymph node retrieval in the treatment of gynecologic cancers. METHODS Data on laparoscopic lymphadenectomy performed for gynecologic malignancies using ultrasonic shears over a 5-year period were collected and analyzed prospectively. RESULTS Laparoscopic lymphadenectomy using ultrasonic shears was performed on 100 patients with a median age of 58 (17-87) years. The types of malignancies included cervical (n = 29), endometrial (n = 48), ovarian (n = 15), fallopian tube (n = 2), malignant mixed mesodermal tumor (n = 2), vaginal (n = 2) and synchronous ovarian and endometrial cancers (n = 2). Sites of lymphadenectomy included pelvic (n = 49), para-aortic (n = 30) or both pelvic and para-aortic (n = 21). The median nodal yield was 22 (0-87). 66/100 were complete lymphadenectomies with a median nodal yield of 28 (2-71). The median length of hospital stay was 2 (1-13) days and the average blood loss was 148 (0-500) ml. Overall complication rate was 13%. There were 3 intra-operative complications, which were all managed laparoscopically. There were no unplanned conversions to laparotomy. There were 10 post-operative complications including port-site metastasis in a patient with positive nodes (n = 1), trocar-site hernia requiring a second laparoscopy (n = 1), deep leg vein thrombosis (n = 1), and a small bowel obstruction (n = 1). CONCLUSIONS This is the largest series to date demonstrating the safety and efficacy of ultrasonic shears in laparoscopic lymphadenectomy for gynecologic malignancies. In addition to the potential for lowering the risk for tissue damage, ultrasonic shears offer multifunctionality which allows for a simpler technique with the use of fewer instruments.

Abstract
OBJECTIVE Evaluate complications of pelvic and para aortic laparoscopic lymphadenectomies in oncologic gynaecology to confirm the surgical approach and include it in current therapy. PATIENTS AND METHODS From December 1998 to March 2004, 915 patients underwent pelvic and/or aortic lymphadenectomies by laparoscopy. Among them, 771 were operated on at the centre Oscar-Lambret (Lille, France), whereas 144 underwent surgery at the institut Claudius-Regaud (Toulouse, France). Laparoscopic lymphadenectomies could be indicated along with other procedures in 98 early adnexal carcinomas, in 237 cervical carcinomas and 216 locally advanced cervical carcinomas. It may also be included as part of cancer therapy with (radical) hysterectomy/trachelectomy in 161 endometrial and 203 up front surgical cervical carcinomas. RESULTS A total of 1102 pelvic and aortic lymphadenectomies have been performed: 714 pelvic (694 trans peritoneal, 20 extra peritoneal) and 388 aortic lymphadenectomies (154 transperitoneal, 234 extraperitoneal). Seventeen open surgeries (1.85%) were necessary for technical reasons or complications. DISCUSSION AND CONCLUSIONS Laparoscopic lymphadenectomies are safe and accurate with no more complications than by laparotomy and no death up to now.

Abstract
OBJECTIVE To determine the incidence and treatment of lymphoceles after retropubic radical prostatectomy (RP). PATIENTS AND METHODS Up to January 2004, 260 patients who had a retropubic RP in one institution by one surgeon were assessed retrospectively, using the patients' notes or the computerized results system to determine whether a lymphocele was suspected and then confirmed by imaging studies (computed tomography or ultrasonography). RESULTS Nine patients developed symptomatic lymphoceles; eight of these were detected by imaging. Four lymphoceles required intervention while the remainder regressed spontaneously. No complications were reported in the group that was treated. CONCLUSION The rate of symptomatic lymphocele formation was low after RP, with an overall incidence of 3.5%. Ultrasonography was effective in detecting lymphoceles and ultrasonographically guided percutaneous drainage an effective treatment.

Abstract
OBJECTIVE To compare the frequencies of pelvic lymphocele formation after laparoscopic and open pelvic lymph node dissection in patients with prostate cancer. MATERIAL AND METHODS A total of 132 patients operated on with pelvic lymph node dissection (PLND) underwent CT scanning of the abdomen and pelvis at a median of 29 days postoperatively. Open pelvic lymph node dissection (OPLND) was performed in 94 patients (71%) and 38 patients (29%) were operated on using a laparoscopic technique (LPLND). The frequency and size of pelvic lymphoceles were registered. Lymphoceles with a horizontal diameter of </=4.9 cm were classified as small and those with a horizontal diameter of >/=5.0 cm were classified as large. RESULTS The overall frequency of lymphoceles was 54%. The frequencies in the OPLND and LPLND groups were 61% and 37%, respectively. A total of 27% of the OPLND patients had large lymphoceles, compared to 8% of the LPLND patients. Three patients (2.3%), all in the OPLND group, had clinically significant lymphoceles. CONCLUSIONS Although the overall frequency of lymphocele formation was high, clinically significant lymphoceles were scarce. LPLND was associated with a statistically significant lower frequency of lymphocele formation compared to OPLND.

Abstract
PURPOSE This article describes our experience of using a totally extraperitoneal approach for endoscopic pelvic lymphadenectomy and inguinal hernia repair with the mesh technique in one procedure. MATERIALS AND METHODS A total of 52 patients underwent modified pelvic lymph node dissection for the staging of prostate cancer. Eight of them had hernia defects; 1 was recurrent. Five patients with direct and 3 patients with indirect inguinal hernias were treated by totally extraperitoneal hernia repair with the placement of a mesh measuring at least 10 x 15 cm (prolene mesh with incision and flap). RESULTS The mean duration of the lymphadenectomy itself was decreased from 150 min (first 20 patients) to 70 min (n = 21-52). The mean additional procedure time for hernioplasty was 15 min. The overall lymph node-positive rate was 9.6%. The complication rate was 7.7%. Four patients developed symptomatic lymphoceles, 1 of whom developed deep venous thrombosis. No complications occurred which were attributed to hernia repair. Morbidity did not rise, and hospitalization time did not increase for the patients who underwent hernioplasty. There were no recurrences or neuralgias on follow-up up to 2 years. CONCLUSIONS By avoiding entry into the peritoneal cavity, the extraperitoneal approach obviates intra-abdominal complications (ileus, bowel injury, peritonitis) in both techniques. The extraperitoneal approach for pelvic lymph node dissection allows concomitant inguinal hernia to be repaired with low morbidity and within an acceptable operating time.

Abstract
Clearly, pelvic lymphadenectomy can provide important staging information in the management of prostate cancer, but this benefit is counterbalanced by a modest increase in morbidity and the significant cost of the procedure. It is difficult to provide universal recommendations concerning the indications for pelvic lymphadenectomy. Part of the problem lies in the fact that urologists perform pelvic lymphadenectomy for several different reasons. Some surgeons perform pelvic lymphadenectomy to better counsel patients after radical prostatectomy about their risk for disease progression and for planning adjuvant radiotherapy or hormonal therapy. For these surgeons, preoperative clinical staging parameters do not exclude patients from pelvic lymphadenectomy, and frozen section analysis intraoperatively provides no useful information. Alternatively, the staging information from pelvic lymphadenectomy can be used to justify cancellation of the subsequent prostatectomy should regional spread of prostate cancer be identified, sparing the patient the morbidity of an unnecessary radical prostatectomy. With this approach, despite the false-negative rate of up to 30%, the expense of frozen section analysis seems justified. For this second group of surgeons, the problem becomes balancing the modest morbidity and cost of pelvic lymphadenectomy against the probability that nodal spread of prostate cancer will be missed if the procedure is omitted. The authors consider a greater than 4% risk for missing regional disease to be unacceptable in this setting. Following this assumption, Table 3 outlines parameters for clinical stage, Gleason score, and preoperative PSA within which pelvic lymphadenectomy is indicated. These recommendations are based on [table: see text] predictions from the Partin nomogram, which has been validated using a series of over 4000 patients. For the large number of patients with clinical T1c disease and a preoperative PSA less than 10 ng/mL, bilateral pelvic lymphadenectomy is indicated only if prostate biopsy identifies tumor of Gleason grade 4 or higher. For lower-grade tumors in this patient population, the risk for nodal metastasis was less than 5% in the Johns Hopkins and Mayo Clinic series of over 5800 patients with prostate cancer. For a large pool of patients, the several thousand dollar cost of pelvic lymphadenectomy and the risk for injury to the obturator nerves and vessels, the formation of lymphoceles, and chronic genital edema can be eliminated with low risk. A nomogram-based approach provides only a starting point for a decision analysis framework to determine whether the surgeon should perform lymphadenectomy at the time of radical prostatectomy because current nomograms predict only lymph node positivity. In a decision analysis framework, some patient and physician value is derived from a negative lymphadenectomy. Moreover, the morbidity associated with pelvic lymphadenectomy and the potential inconvenience associated with treating such morbidity also would be factored into the decision. Consequently, a decision analysis framework that takes into account prognostic value, costs, morbidity, and health state uses ultimately will provide the most informative method for determining when pelvic lymphadenectomy is indicated in patients with prostate cancer.
