Long-term oncological and surgical outcomes after Video Endoscopic Inguinal Lymphadenectomy (VEIL) in patients with penile cancer

ABSTRACT Objective: To report outcomes from the largest multicenter series of penile cancer patients undergoing video endoscopic inguinal lymphadenectomy (VEIL). Materials and Methods: Retrospective multicenter analysis. Authors of 21 centers from the Penile Cancer Collaborative Coalition-Latin America (PeC-LA) were included. All centers performed the procedure following the same previously described standardized technique. Inclusion criteria included penile cancer patients with no palpable lymph nodes and intermediate/high-risk disease and those with non-fixed palpable lymph nodes less than 4 cm in diameter. Categorical variables are shown as percentages and frequencies whereas continuous variables as mean and range. Results: From 2006 to 2020, 210 VEIL procedures were performed in 105 patients. Mean age was 58 (45-68) years old. Mean operative time was 90 minutes (60-120). Mean lymph node yield was 10 nodes (6-16). Complication rate was 15.7%, including severe complications in 1.9% of procedures. Lymphatic and skin complications were noted in 8.6 and 4.8% of patients, respectively. Histopathological analysis revealed lymph node involvement in 26.7% of patients with non-palpable nodes. Inguinal recurrence was observed in 2.8% of patients. 10y- overall survival was 74.2% and 10-y cancer specific survival was 84.8%. CSS for pN0, pN1, pN2 and pN3 were 100%, 82.4%, 72.7% and 9.1%, respectively. Conclusion: VEIL seems to offer appropriate long term oncological control with minimal morbidity. In the absence of non-invasive stratification measures such as dynamic sentinel node biopsy, VEIL emerged as the alternative for the management of non-bulky lymph nodes in penile cancer.

Gonadal Function and Reproductive System Anatomy in Postpubertal Prune-Belly Syndrome Patients.

OBJECTIVE: To gain insight into the causes of infertility in Prune Belly Syndrome (PBS) by evaluating reproductive system anatomy and gonadal function in a cohort of postpubertal PBS patients. METHODS: We contacted all PBS patients 14 years old or older treated and followed at our institution. Age at orchiopexy, type of orchiopexy (with or without ligation of gonadal vessels), testicular volumes and positions were evaluated. Pelvic magnetic resonance imaging (to assess prostate size, seminal vesicles, and vas) and hormonal profile were ordered. Sperm analysis and analysis of urine after masturbation were performed after informed consent. RESULTS: Fifteen patients were included in this study. Mean age was 19.2 years. Mean age at orchiopexy was 18 months. Fourteen patients (93.3%) had normal and orthotopic testes. Mean testicular volume was 6.9 cc. Eight patients collected semen, 5 of them (62.5%) had spermatozoa in the specimen and motile sperm was found in 4 (50%). Mean hormone levels were LH: 5.3 mg/dL, FSH: 6.9 mg/dL, testosterone 531 mg/dL. Magnetic resonance imaging revealed hypoplastic prostates in 66.6% and unilateral seminal vesicle absence in 66.6%. No vasal abnormality was noted. CONCLUSION: Patients with PBS may have normal sexual hormonal levels. Motile spermatozoa were found in half of the patients. Our study highlights a high prevalence of prostate and seminal vesicle abnormalities that may represent an important cause for their infertility.

Modified abdominoplasty for patients with the Prune Belly syndrome.

OBJECTIVE: To present the results of a new technique for abdominoplasty in patients with the Prune Belly syndrome (PBS). METHODS: Since 1985, 46 children with PBS underwent surgical treatment that included urinary tract reconstruction (UTR), orchidopexy, and abdominoplasty. In 41 patients, we performed the abdominoplasty as follows: (1) fusiform longitudinal resection of the mid-abdominal skin and subcutaneous tissue, with preservation of the musculo-aponeurotic fascia (MAF) and umbilicus, (2) ellipsoid unilateral longitudinal incision of the MAF in the most weakened side of the abdomen, producing 2 flaps, with the umbilicus being kept intact in the widest flap, (3) after UTR and bilateral orchiopexy, suture fixation of the widest MAF layer to the inner side of the contralateral abdominal wall, creating an inner MAF layer, (4) lateral suture fixation of the other flap over the inner layer, creating an outer MAF layer with a buttonhole exposing the umbilicus, that is sutured to the outer layer, and (5) approximation of the skin edges with incorporation of the umbilicus in the suture. RESULTS: Skin coaptation was excellent in all patients, and no trimming was necessary in incision extremities. There was no dehiscence or skin necrosis and all patients presented immediate improvement of the abdominal tonus and appearance. Further improvement with growth was observed in all except 4 patients, 2 requiring secondary abdominoplasties. CONCLUSION: We conclude that this technique is applicable in all forms of weakened abdomen typical of PBS, even in asymmetrical cases, requiring only 1 MAF incision, with good cosmetic and functional results.

Long-term Treatment Outcomes Between Surgical Correction and Conservative Management for Penile Fracture: Retrospective Analysis.

PURPOSE: Early surgical management is the standard of care for penile fracture. Conservative treatment is an option with recent reports revealing lower success rates. We reviewed the data and long-term outcomes of patients with penile injury submitted to surgical or conservative treatment. MATERIALS AND METHODS: Between January 2004 and February 2012, 42 patients with penile blunt trauma on an erect penis were admitted to our center. We analyzed the following variables: age, etiology, symptoms and signs, diagnostic tests, treatment used, complications and erectile function during the follow-up. One patient was excluded due to missing information. Thirty-five patients underwent surgical repair and 6 patients were submitted to conservative management. RESULTS: Mean follow-up was 19.2 months (range, 7 days to 72 months). The mean elapsed time from trauma to surgery was 21.3±12.5 hours. Trauma during sexual relationship was the main cause (80.9%) of penile fracture. Urethral injury was present in five patients submitted to surgery. Dorsal vein injury occurred in three patients with false penile fracture and concomitant spongious corpus lesion was present in three patients. During follow-up, 31 cases (88.6%) of the surgical group and four cases (66.7%) of the conservative group reported sufficient erections for intercourse, with no voiding dysfunction and no penile curvature. However, the remaining two patients (33.3%) from the conservative group developed erectile dysfunction and three patients (50%) developed penile deviation. CONCLUSIONS: Surgical approach provides excellent functional outcomes and lower complications. Early surgical management of penile fracture provides superior results and conservative approach should be avoided.

Topical betamethasone and hyaluronidase in the treatment of phimosis in boys: a double-blind, randomized, placebo-controlled trial.

PURPOSE: To compare the efficacy of three different formulations containing Betamethasone Valerate versus placebo in the topical treatment of phimosis. As a secondary goal, we compared the outcomes after 30 and 60 days of treatment. MATERIALS AND METHODS: Two hundred twenty boys aged 3 to 10 years old with clinical diagnosis of phimosis were enrolled. Patients were randomized to one of the following groups: Group 1: Betamethasone Valerate 0.2% plus Hyaluronidase; Group 2: Betamethasone Valerate 0.2%; Group 3: Betamethasone Valerate 0.1% or Group 4: placebo. Parents were instructed to apply the formula twice a day for 60 days and follow-up evaluations were scheduled at 30, 60 and 240 days after the first consultation. Success was defined as complete and easy foreskin retraction. RESULTS: One hundred ninety-five patients were included at our final analysis. Group 1 (N = 54), 2 (N = 51) and 3 (N = 52) had similar success and improvement rates, all treatment groups had higher success rates than placebo (N = 38). After 60 days of treatment, total and partial response rates for Groups 1, 2 and 3 were 54.8% and 40.1%, respectively, while placebo had a success rate of 29%. Success and improvement rates were significantly better in 60 days when compared to 30 days. CONCLUSIONS: Betamethasone Valerate 0.1%, 0.2% and 0.2% in combination with Hyaluronidase had equally higher results than placebo in the treatment of phimosis in boys from three to ten years-old. Patients initially with partial or no response can reach complete response after 60 days of treatment.

Long-term outcome of laparoscopic pyeloplasty: multicentric comparative study of techniques and accesses.

PURPOSE: The aim of the present study was to analyze long-term follow up (18-108 months) of different techniques and routes for laparoscopic repair of uretero-pelvic junction obstruction comparing efficacy and results. MATERIALS AND METHODS: A retrospective analyses of 133 laparoscopic pyeloplasties in 132 patients (mean age 35 years) between August 1995 and November 2008 was performed. Transperitoneal route was performed in 114 patients, and retroperitoneal route was performed in 19 patients. Different repair techniques (dismembered and non-dismembered) were applied at the surgeon's discretion. RESULTS: Average operative time was 127 minutes (range 45-370). Average blood loss was 127 mL, and mean hospital stay was 24 hours. Complications occurred in 9.6% of surgeries, and conversion rate was 1.7%. Urinary leak occurred after eight (6.1%) surgeries, all managed conservatively. Overall success rate of laparoscopic repair was 96%, higher for dismembered versus non-dismembered procedures (97% versus 89%, P = .04). CONCLUSION: Laparoscopic pyeloplasty is a reproducible, highly effective, and minimally invasive treatment for uretero-pelvic junction obstruction. Surgical technique affects operative time and long-term success rates. Dismembered techniques seem to remain more effective after a long-term follow up. Surgical route does not seem to affect success rates.

Video game as a preoperative warm-up for laparoscopic surgery / Jogo de video game como aquecimento pré-operatório para cirurgia laparoscópica

Objective: The aim of the present study was to assess the influence of video game as warm-up before dry-lab laparoscopic activities. Methods: Eleven medical students participated in this prospective randomized crossover study. Students were divided into two groups. Students in Group 1 had to execute an interrupted suture with the dominant hand using a standardized technique (non-video game group). Students in Group 2 performed the same suture, but after playing a video game match (video game group). After this initial task, groups were crossed. The time spent to complete each task was recorded, and the participants and observers had to judge the performance for each laparoscopic exercise. These variables were used as a measure of performance. Results: Mean time for laparoscopic surgery in this subset of inexperienced laparoscopic students was similar between non-video game versus video game groups (254.6 ± 187.7 versus 255.8 ± 183.6; p = 0.875). Subjective impression of observers regarding students? performance was also similar (p = 0.662), but subjective impression of the participant about his own performance was different between both groups, with 64.7 versus 20.0% of participants that considered their performance good for video game versus non-video game groups (p = 0.044). Conclusions: In conclusion, video games used as warm-up for laparoscopic practice seem to make inexperienced surgeons more confident and comfortable with the procedures, even though objective measures, as operative time and observers impression of surgeons performance do not seem to be affected by video game warm-up.

Objetivo: Avaliar o efeito de um jogo de video game como aquecimento pré-operatório para o cirurgião laparoscópico. Métodos: Foi realizado um estudo prospectivo cruzado com 11 estudantes de medicina e médicos residentes com pouca experiência em laparoscopia. Um grupo realizou suturas laparoscópicas em caixa preta sem aquecimento inicial, enquanto outro realizou aquecimento por meio de jogos de video game. Os grupos foram cruzados em um segundo momento. Resultados: O tempo médio para confecção de sutura laparoscópica foi semelhante entre os grupos Direto versus Video game (254,6 ± 187,7 versus 255,8 ± 183,6; p = 0,875). A impressão subjetiva dos avaliadores sobre o grau de dificuldade para a realização da tarefa também foi semelhante entre os grupos (p = 0,662). Em relação à percepção do cirurgião quanto ao grau de dificuldade para a realização do procedimento cirúrgico, observou-se que os cirurgiões do grupo Video game versus Direto tiveram uma percepção subjetiva de maior facilidade para a realização do exercício, sendo que a porcentagem de exercícios considerados de dificuldade baixa ou moderada foi de 64,7 versus 20,0% entre os grupos (p = 0,044). Conclusões: O emprego de jogo de video game como aquecimento para a cirurgia laparoscópica em cirurgiões pouco experientes parece torná-los mais receptivos para as dificuldades do procedimento, embora não altere o tempo para a realização dos procedimentos e nem a percepção alheia do grau de dificuldade.

Laparoscopic renal surgery in infants and children: is it a feasible and safe procedure for all pediatric age groups?

PURPOSE: Although laparoscopy is considered the mainstay for most renal procedures in adults, its role in the pediatric population is still controversial, especially for smaller children. We reviewed our experience in pediatric renal laparoscopic surgery in three pediatric age groups in an attempt to identify if age has an impact on feasibility and surgical outcomes. MATERIALS AND METHODS: From November 1995 to May 2006, 144 pediatric laparoscopic renal procedures were performed at our institution. The charts of these patients were reviewed for demographic data, urologic pathology and surgical procedure, as well as perioperative complications and post-operative outcomes. The findings were stratified into 3 groups, according to patient age (A: < 1 year, B: 1 to 5 years and C: 6-18 years). RESULTS: Median age of the patients was 4.2 years (42 days - 18 years). We performed 54 nephrectomies, 33 nephroureterectomies, 19 upper pole nephrectomies, 11 radical nephrectomies, 22 pyeloplasties and 4 miscellaneous procedures. The 3 age groups were comparable in terms of the procedures performed. Conversion rates were 0%, 1.4% and 1.9% for groups A, B and C, respectively (p = 0.72). Incidence of perioperative complications was 5%, 8.2% and 7.8% for age groups A to C, respectively (p = 0.88). CONCLUSIONS: Most renal procedures can be performed safely by laparoscopy in the pediatric population, with excellent aesthetic and functional outcomes. The morbidity related to the procedure was minimal irrespective of the age group.

Can video endoscopic inguinal lymphadenectomy achieve a lower morbidity than open lymph node dissection in penile cancer patients?

BACKGROUND AND PURPOSE: Radical lymphadenectomy improves survival in penile cancer patients, but the morbidity of the classic open procedure exceeds 50%. We report the updated results of Video Endoscopic Inguinal Lymphadenectomy (VEIL), an original minimally invasive procedure recently reported for extended inguinal node dissection in clinical settings. PATIENTS AND METHODS: Fifteen consecutive patients who underwent the VEIL technique were prospectively followed and included in this study. The first 10 patients underwent bilateral inguinal dissection for nonpalpable lymph nodes: VEIL at one side and standard open lymph node dissection at the other side. A second cohort consisted of five patients who underwent bilateral VEIL, either for nonpalpable or for palpable (N1) inguinal nodes. Operative data and postoperative outcomes were assessed, and VEIL and the open technique were compared. RESULTS: Twenty limbs underwent VEIL and 10 limbs underwent the open procedure. Mean operative time was 120 minutes for VEIL and 92 minutes for the open procedure. There was no difference in the number of nodes removed or in the positivity for metastatic lymph nodes. Complications were observed in 70% of limbs that underwent open surgery and in 20% of limbs that underwent VEIL (P 0.015). Patients who underwent a bilateral VEIL could be discharged from the hospital after an average of 24 hours (range 12-36 hrs), while patients who underwent an open dissection in addition to contralateral VEIL were discharged after an average of 6.4 days (range 5-10 d) There were no recurrences detected during a mean follow-up of 31.9 months (median 33 months). CONCLUSION: This preliminary series suggests that VEIL can reduce morbidity, including hospitalization times,compared with standard open surgery. Oncologic results are premature but seem similar to the results from the conventional open operation. VEIL is a promising minimally invasive approach for radical inguinal dissection in penile cancer patients with nonpalpable or low-volume palpable inguinal disease.

Video endoscopic inguinal lymphadenectomy: a new minimally invasive procedure for radical management of inguinal nodes in patients with penile squamous cell carcinoma.

PURPOSE: Video endoscopic inguinal lymphadenectomy is a recently described lymphadenectomy with the same template of the open technique but performed with laparoscopic instruments under video guidance. It was developed to decrease procedure related morbidity while maintaining good oncological results. We report our initial results in a trial comparing video endoscopic inguinal lymphadenectomy with standard inguinal lymphadenectomy. MATERIALS AND METHODS: From 2003 to 2005, 10 patients with penile carcinoma who were at high risk for inguinal metastases underwent bilateral inguinal lymphadenectomy. We performed standard lymphadenectomy in 1 limb and video endoscopic inguinal lymphadenectomy on the contralateral side. Perioperative results and followup data were compared. RESULTS: No intraoperative complications occurred. Mean operative time was 92 and 126 minutes for open and endoscopic surgery, respectively (p=0.00002). Despite the small number of patients we noted a decrease in cutaneous complications with video endoscopic inguinal lymphadenectomy (0% vs 50%, p=0.017) and a trend toward decreased overall morbidity with this endoscopic technique (20% vs 70%, p=0.059). The mean number of retrieved and positive lymph nodes were similar for the 2 techniques. At a mean followup of 18.7 months (range 12 to 31) no signs of recurrence or disease progression were noted. In the postoperative period 9 of the 10 patients identified video endoscopic inguinal lymphadenectomy as the preferred technique in terms of surgical morbidity. CONCLUSIONS: Video endoscopic inguinal lymphadenectomy is a safe and feasible technique in patients with penile carcinoma and nonpalpable nodes. These preliminary results suggest that video endoscopic inguinal lymphadenectomy may decrease postoperative morbidity without compromising oncological control. Future studies should include the bilateral procedure, longer term followup and a greater number of patients.

Video endoscopic inguinal lymphadenectomy (VEIL): initial case report and comparison with open radical procedure.

OBJECTIVES: Inguinal metastases are one of the major determinants of mortality in patients with penile cancer. In high risk patients, while prophylatic inguinal lymphadenectomy may offer survival advantages, it still carries a relatively high morbidity. We describe in this paper the first report of the Video Endoscopic Inguinal Lymphadenectomy (VEIL) in the clinical practice, a technique which aims at reducing the morbidity of the procedure without compromising the cancer control or reducing the template of the dissection. METHODS: A 40 year old male with a pT2 penile cancer underwent prophylatic bilateral inguinal lymphadenectomy 6 weeks after partial penectomy. We performed the VEIL technique at the right and a standard radical inguinal lymphadenectomy through an inguinal incision at the left (control). After developing a plane deep to Scarpa's fascia, locating 3 ports and infusing gas at 5-10 mmHg, a retrograde dissection with the same limits as the standard open surgery was performed. Intraoperative data, patology, post operatory evolution and oncological follow-up is described for both sides. RESULTS: Operative time was 130 min for the VEIL and 90 min for open surgery. Eight and 7 lymphnodes were retrieved at the VEIL side and open side, respectively, and none of then showed positivity at pathology. There were no complications in the limb which underwent the VEIL and there was skin necrosis in the side of the open surgery. After 25 months of follow up, no signs of disease progression were noted. Asked about how he felt about both surgeries, the patient chose the endoscopic approach. CONCLUSION: VEIL is feasible in clinical practice. New studies with a greater number of patients and long-term follow-up may confirm the oncological efficacy and possible lower morbidity of these new approach.

Video endoscopic inguinal lymphadenectomy (VEIL): minimally invasive resection of inguinal lymph nodes.

OBJECTIVES: Describe and illustrate a new minimally invasive approach for the radical resection of inguinal lymph nodes. SURGICAL TECHNIQUE: From the experience acquired in 7 operated cases, the video endoscopic inguinal lymphadenectomy (VEIL) technique was standardized in the following surgical steps: 1) Positioning of the inferior member extended in abduction, 2) Introduction of 3 work ports distal to the femoral triangle, 3) Expansion of the working space with gas, 4) Retrograde separation of the skin flap with a harmonic scalpel, 5) Identification and dissection of the long saphenous vein until the oval fossa, 6) Identification of the femoral artery, 7) Distal ligature of the lymph node block at the femoral triangle vertex, 8) Liberation of the lymph node tissue up to the great vessels above the femoral floor, 9) Distal ligature of the long saphenous vein, 10) Control of the saphenofemoral junction, 11) Final liberation of the surgical specimen and endoscopic view showing that all the tissue of the region was resected, 12) Removal of the surgical specimen through the initial orifice, 13) Vacuum drainage and synthesis of the incisions. COMMENTS: The VEIL technique is feasible and allows the radical removal of inguinal lymph nodes in the same limits of conventional surgery dissection. The main anatomic repairs of open surgery can be identified by the endoscopic view, confirming the complete removal of the lymphatic tissue within the pre-established limits. Preliminary results suggest that this technique can potentially reduce surgical morbidity. Oncologic follow-up is yet premature to demonstrate equivalence on the oncologic point of view.

Hand-assisted laparoscopic nephrectomy as a minimally invasive option in the treatment of large renal specimens

INTRODUCTION: We describe our experience with hand-assisted laparoscopy (HAL) as an option for the treatment of large renal specimens. MATERIALS AND METHODS: Between March 2000 and August 2004, 13 patients candidate to nephrectomies due to benign renal conditions with kidneys larger than 20 cm were included in a prospective protocol. Unilateral nephrectomy was performed in cases of hydronephrosis (6 patients) or giant pyonephrosis (4 patients). Bilateral nephrectomy was performed in 3 patients with adult polycystic kidney disease (APKD) with low back pain refractory to clinical treatment previous to kidney transplant. The technique included the introduction of 2 to 3 10 mm ports, manual incision to allow enough space for the surgeon's wrist without a commercial device to keep the pneumoperitoneum. The kidney was empty, preferably extracorporeally, enough to be removed through manual incision. We have assessed operative times, transfusions, complications, conversions, hospital stay and convalescence. RESULTS: The patients mean age (9 women and 4 men) was 58 years. Mean operating time was 120 n 10 min (hydronephrosis), 160 n 28 min (pyonephrosis) and 190 n 13 min (bilateral surgery for APKD). There was a need for a conversion in 1 case and another patient needed a transfusion due to a lesion in the renal vein; 2 patients had minor complications. CONCLUSION: HAL surgery is a minimally invasive alternative in the treatment of large renal specimens, with or without significant inflammation.
