RESUMEN
STUDY OBJECTIVES: Pelvic lymph node dissection (PLND) is part of the primary treatment for early-stage cervical cancer and high-intermediate risk or high-risk endometrial cancer. Pelvic lymphocele is a postoperative complication of PLND, and when symptomatic, lymphoceles necessitate treatment. The aim of this study was to investigate the incidence and risk factors of symptomatic lymphocele after robot-assisted laparoscopic PLND in cervical and endometrial cancer. DESIGN: Retrospective cohort study. SETTING: Single-center academic hospital. PATIENTS: Two hundred and fifty-eight patients with cervical cancer and 129 patients with endometrial cancer. INTERVENTIONS: Pelvic lymphadenectomy by robot-assisted laparoscopic surgery. MEASUREMENTS AND MAIN RESULTS: The authors retrospectively included all patients with early-stage cervical cancer and high-intermediate risk or high-risk endometrial cancer who underwent pelvic lymphadenectomy by robot-assisted laparoscopic surgery between 2008 and 2022. Medical records were reviewed for the occurrence of a symptomatic lymphocele. Univariate and multivariate logistic regression analyses were conducted to identify risk factors for developing a symptomatic lymphocele. In total, 387 patients, 258 with cervical cancer and 129 with endometrial cancer, were included in the study. The overall incidence of symptomatic lymphoceles was 9.6% with a median follow-up of 47 months [interquartile range 23-61]. For the entire cohort, smoking was the only significant risk factor for symptomatic lymphoceles identified in univariate (OR 2.47, 95% CI 1.19-5.11) and multivariate analysis (OR 2.42, 95% CI 1.16-5.07). For cervical cancer, body mass index (BMI) (OR 1.09, 95% CI 1.00-1.17) and prior abdominal surgery (OR 2.75, 95% CI 1.22-6.17) were also identified as significant independent risk factors. For endometrial cancer, age was identified as a significant independent risk factor (OR 0.90, 95% CI 0.83-0.97). CONCLUSION: This single-center cohort study demonstrated an incidence of almost 10% of symptomatic lymphoceles after robot-assisted laparoscopic PLND for cervical cancer and endometrial cancer, with a higher risk observed among patients who smoke at the time of diagnosis. Furthermore, risk factors differ between the 2 populations, necessitating further studies to establish risk models.

PURPOSE: Lymphocele formation following anterior lumbar interbody fusion (ALIF) is not common, but it can pose diagnostic and treatment challenges. The purpose of this case is to report for the first time the treatment of a postoperative lymphocele following a multi-level ALIF using a peritoneal window made through a minimally invasive laparoscopic approach. METHODS: Case report. RESULTS: A 74-year-old male with a history of prostatectomy and pelvic radiation underwent a staged L3-S1 ALIF (left paramedian approach) and T10-pelvis posterior instrumented with L1-5 decompression/posterior column osteotomies for degenerative scoliosis and neurogenic claudication. Three weeks after surgery, swelling of the left abdomen and entire left leg was reported. Computed tomography of the abdomen/pelvis demonstrated a large (19.2 × 12.0 × 15.4 cm) retroperitoneal fluid collection with compression of the left ureter and left common iliac vein. Fluid analysis (80% lymphocytes) was consistent with a lymphocele. Percutaneous drainage for 4 days was ineffective at clearing the lymphocele. For more definitive management, the patient underwent an uncomplicated laparoscopic creation of a peritoneal window to allow passive drainage of lymphatic fluid into the abdomen. Three years after surgery, he had no back or leg pain, had achieved spinal union, and had no abdominal swelling or left leg swelling. Advanced imaging also confirmed resolution of the lymphocele. CONCLUSIONS: In this case report, creation of a peritoneal window minimally invasively via a laparoscope allowing passive drainage of lymphatic fluid into the abdomen was safe and effective for management of an abdominal lymphocele following a multi-level ALIF.

INTRODUCTION: Symptomatic lymphocele remains a relevant complication after pelvic tumor surgery. This study aims to investigate how the number of lymph nodes removed may influence postoperative outcomes and if it increases the probability of detecting lymph node metastasis. METHODS: The study included 500 patients who underwent RARP including lymphadenectomy performed by a single surgeon. Patients were divided into two groups: group 1 consisted of 308 patients with 20 or fewer lymph nodes removed (mean 15), while group 2 had 192 patients with over 20 nodes removed (mean 27). Perioperative data were analyzed, and postoperative outcomes were compared between groups. RESULTS: Overall, lymph node metastasis was detected in 17.8% of men. In detail, out of 19.6 lymph nodes removed, an average of 3.14 lymph nodes per patient showed metastasis, with a slightly higher incidence of 19.7% in group 2 compared to 16.5% in group 1, though not statistically significant (p = 0.175). The number of lymph node metastases was significantly higher in group 2 patients (3.47) versus group 1 (2.37) (p = 0.048). All complications except symptomatic lymphoceles (p = 0.004) were not significantly different between groups. Univariate linear regression analysis revealed no correlation between the number of removed lymph nodes and symptomatic lymphocele. However, it did correlate with catheter days and readmissions. CONCLUSION: A correlation may exist between the number of lymph nodes removed during RARP and an increased incidence of complications, particularly symptomatic lymphocele. A more extensive PLND may result in prolonged catheter days and increased readmissions. With the increased extent of pelvic lymphadenectomy, the probability of detecting lymphogenic metastasis rises. The diagnostic value of PLND is well established. Further randomized trials are needed to weigh its necessity and extent.

INTRODUCTION: Postoperative chronic lymphocele and lymphedema represent severe burdens for soft tissue sarcoma patients who are already physically handicapped after an extensive surgery and a long recovery time. Incidences are high in the upper medial thigh. We have shifted our focus to lymphedema and lymphocele risk reduction with immediate lymphovenous anastomosis (LVA) after sarcoma resection. METHODS: We performed immediate lymphatic reconstruction in 11 patients after soft tissue sarcoma resection in the upper medial thigh. The postoperative course was followed up closely, and postoperative occurrence of lymphocele and lymphedema was clinically assessed. A literature search outlining the latest clinical data, current treatment strategy landscape, and their application into clinical practice was added to the investigation. RESULTS: A total of 19 LVA and 2 lympho-lymphatic anastomoses were performed in 11 patients immediately after tumor resection in an end-to-end manner. We found a postoperative lymphedema rate of 36% and a postoperative lymphocele rate of 27%. Mean follow-up time was 17 months. Average tumor volume was 749 cc. Our literature search yielded 27 articles reporting on immediate LVA in cancer patients. Incidences of secondary lymphedema after LVA for lymphedema prevention vary between 0% and 31.1%. Lymphocele prevention with LVA is poorly studied in sarcoma patients. CONCLUSION: Immediate lymphatic reconstruction improved the overall postoperative course of our patients. The current literature does not serve with high-quality studies about primary LVA preventing lymphedema and lymphocele formation. We conclude that this technique should be seen as an additional concept to achieve overall better postoperative outcomes in these challenging surgical settings. We strongly recommend to either anastomose or ligate severed lymphatics under the microscope primarily after sarcoma resection in the upper medial thigh area.

INTRODUCTION: Robot-assisted radical prostatectomy (RARP) has become a popular surgical approach for localized prostate cancer due to its favorable oncological and functional outcomes, as well as lower morbidity. In cases of intermediate- and high-risk prostate cancer, bilateral pelvic lymphadenectomy (PLND) is recommended as an adjunct to RARP (1-3). Despite its benefits, PLND can lead to surgical complications, with postoperative lymphocele formation being the most common. Most postoperative lymphoceles are clinically insignificant with variable incidence, reaching up to 60% of cases 4. However, a small percentage of patients 2-8% may experience symptomatic lymphoceles (SL), which can cause significant morbidity (4, 5). SURGICAL TECHNIQUE: We perform our RARP technique with our standard approach in all patients (6). After vesicourethral anastomosis a modified PF created to prevent symptomatic lymphocele. We start by suturing the peritoneal fold on the right side, medially to the vas deferens, followed by a similar stitch on the left side to approximate the edges in the midline. A running suture bunches the bladder peritoneum from both sides, passing through the pubic bone periosteum to secure it in place (7). This approach keeps the lateral pelvic gutters open for lymphatic drainage, while allowing fluid drainage from the true pelvis into the abdomen. A pelvic ultrasound was done for all patients at 6 weeks post operative, and additional clinical follow-up was carried out at 3 months following surgery. CONSIDERATIONS: We have demonstrated a modified technique of peritoneal flap (PBFB) with an initial decrease in postoperative symptomatic lymphoceles, the technique is feasible, safe, does not add significant morbidity, and does not require a learning curve.

Early postoperative wound complications in revascularization procedures in the groin very often include complications associated with injury to the lymphatic system such as lymphocele and lymphorrhea with subsequent local infectious complications and the risk of infection of prosthetic grafts. We present a case report of successful treatment of postoperative lymphocele with subsequent lymphatic fistula and dehiscence of the surgical wound by intranodal embolization of the injured lymph node with Histoacryl tissue glue.

PURPOSE: This study evaluated the effectiveness of sclerotherapy in treating lymphoceles after kidney transplantation, focusing on factors such as recurrence rates and procedural success. MATERIALS AND METHODS: Retrospective studies using sclerotherapy as the only form of treatment for postrenal transplant lymphoceles were included. All studies used percutaneous transcatheter sclerotherapy as treatment, and the success rate of the intervention was recorded. Sixty-one references were obtained by manually searching the MEDLINE (n = 20), Embase (n = 41), and Cochrane Library databases (n = 0) for retrospective research studies that included the keywords "sclerotherapy post renal transplant lymphoceles." After removing 3 duplicates, 50 of the remaining articles were excluded after the screening, and the remaining studies were extracted for demographic data and our primary outcome of the success rate of sclerotherapy. RESULTS: A descriptive analysis of the outcomes and complication rates associated with sclerotherapy interventions for lymphoceles is provided. A high degree of variation across the different studies was observed. According to the Kruskal-Wallis test, there was no correlation between the sclerosant used and the sclerotherapy complication rate (P = .472) or the success rate (P = .591). There was also no correlation between the gender of the patient and the success rate; however, there was a significant difference in the complication rate by gender (P < .005). CONCLUSIONS: In conclusion, different sclerosant products have been used for therapy with no consensus on the most efficacious product because the success rate has been variable. In addition, the gender of the patient may influence the complication rates associated with sclerotherapy for lymphoceles in patients post-kidney transplant.

Lymphocele is one of the most common complications after radical prostatectomy. Multiple authors have proposed the use of vessel sealants or peritoneal interposition techniques as preventive interventions. This study aimed to aggregate and analyze the available literature on different interventions which seek to prevent lymphocele through a Bayesian Network. A systematic review was performed to identify prospective studies evaluating strategies for lymphocele prevention after robot assisted laparoscopic prostatectomy + pelvic lymph node dissection. Data was inputted into Review Manager 5.4 for pairwise meta-analysis. Data was then used to build a network in R Studio. These networks were used to model 200,000 Markov Chains via MonteCarlo sampling. The results are expressed as odds ratios (OR) with 95% credible intervals (CrI). Meta-regression was used to determine coefficient of change and adjust for pelvic lymph node dissection extent. Ten studies providing data from 2211 patients were included. 1097 patients received an intervention and 1114 patients served as controls. Interposition with fenestration had the lowest risk of developing a lymphocele (OR 0.14 [0.04, 0.50], p = 0.003). All interventions, except sealants or patches, had significant decreased odds of lymphocele rates. Meta-analysis of all the included studies showed a decreased risk of developing a lymphocele (OR 0.42 [0.33, 0.53], p < 0.00001) for the intervention group. Perivesical fixation and interposition with fenestration appear to be effective interventions for reducing the overall incidence of lymphocele.

BACKGROUND The purpose of the present study was to analyze the rate of lymphoceles in kidney transplant operations meticulously performed by the same senior surgeon. MATERIAL AND METHODS The present study included 315 patients who were operated on in our organ transplantation center and followed up in the polyclinic after July 2013. The patients were retrospectively divided into 2 groups: patients with and without lymphocele. Symptomatic lymphocele (SL) has been defined as symptomatic fluid collection around the graft that necessitates an intervention for the graft or patient. RESULTS Lymphocele was observed in 82 (26%) patients. An intervention was needed in 16 (5.1%) of these cases. Demographic data such as age and sex of both groups were similar. Lymphocele cases were mostly asymptomatic, with a size <6 cm (75.6%). However, intervention was needed in 16 (75%) of the patients with a size ≥6 cm that were symptomatic. The length of time on dialysis in the pretansplant period was shorter in the group that developed lymphocele, and a lower rate of graft loss was observed in these patients. No statistically significant difference was found between the 2 groups in terms of rejection rates, serum albumin/globulin levels, and development of de novo DSA. CONCLUSIONS The risk factors reported in the literature related with lymphocele formation were not found to be statistically significant in our study. Complications, except lymphocele, were observed less frequently, but lymphocele formation was encountered in our patients despite meticulous surgery.

Introduction: For localized clinically significant prostate cancer (csPCa), robotically assisted laparoscopic radical prostatectomy (RALP) is the gold standard surgical treatment. Despite low overall complication rate, continued quality assurance (QA) efforts to minimize complications of RALP are important, particularly given movement toward same-day discharge. In 2019, National Surgical Quality Improvement Program (NSQIP) began collecting RALP-specific data. In this study, we assessed pre- and perioperative factors associated with postoperative complications for RALP to further QA efforts. Materials and Methods: Surgical records of csPCa patients who underwent RALP were retrieved from the 2019 to 2021 NSQIP database, including new RALP-specific data. Multivariate logistic regression evaluated the association between risk factors and outcomes specific to RALP and pelvic lymph node dissection (PLND). Input variables included American Society of Anesthesiologists (ASA) class, age, operative time, and body mass index (BMI). Variables from the extended dataset with PLND information included number of nodes evaluated, perioperative antibiotics, postoperative venous thromboembolism (VTE) prophylaxis, history of prior pelvic surgery, and history of prior radiotherapy (RT). Outcomes of interest were any surgical complication, infection, pulmonary embolism, deep venous thrombosis, acute kidney injury, pneumonia, lymphocele, and urinary/anastomotic leak (UAL). Results: A total of 11,811 patients were included with 6.1% experiencing any complication. Prior RT, prior pelvic surgery, older age, higher BMI, lack of perioperative antibiotic therapy, longer operative time, PLND, and number of lymph nodes dissected were associated with higher risk of postoperative complications. Regarding procedure-specific complications, there were increased odds of UAL with prior RT, prior pelvic surgery, longer operative time, and higher BMI. Odds of developing lymphocele increased with prior pelvic surgery, performance of PLND, and increased number of nodes evaluated. Conclusion: In contemporary NSQIP data, RALP is associated with low complication rates; however, these rates have increased compared with historical studies. Attention to and counseling regarding risk factors for peri- and postoperative complications are important to set expectations and minimize risk of unplanned return to a health care setting after discharge.

OBJECTIVES: Lymphocele formation after kidney transplant is a common complication that causes significant morbidity. In this study, we aimed to evaluate the safety and effectiveness of intraoperative prophylactic povidone-iodine sclerotherapy through the closed suction drain to prevent lymphocele after kidney transplant. MATERIALS AND METHODS: In this retrospective comparative single-institution study, we compared patients who underwent intraoperative prophylactic povidone-iodine sclerotherapy through the closed suction drain (group A) with patients who did not receive sclerotherapy (group B). Patients were treated between September 2017 and July 2023. Atthe end of the kidney transplant surgery, after the closure of the external oblique muscle layer and before skin closure, 10 mL of 10% povidone-iodine in 40 mL of normal saline were instilled via the closed suction drain and dwelled in the cavity for 30 minutes. RESULTS: During the study period, 300 living-related donor kidney transplants were performed. Prophylactic povidone-iodine sclerotherapy was performed in 150 patients (50%).We noted a significantly lower incidence of lymphorrhea and lymphocele in group A. On postoperative days 1 and 5, we noted a significant reduction in drain output in group A (P < .001). One patient in group A and 5 patients in group B required ultrasonography-guideddrainage andpovidone-iodine sclerotherapy. No sclerotherapy-related complications were reported after a median follow-up of 16 months (range, 3-29 months). CONCLUSIONS: Intraoperative prophylactic povidoneiodine sclerotherapy appears to be an easy, safe, and effective procedure for preventing lymphatic complications after living donor kidney transplant.

OBJECTIVE: To conduct a systematic review and meta-analysis to evaluate the association of a peritoneal interposition flap (PIF) with lymphocele formation following robotic-assisted laparoscopic radical prostatectomy (RALP) with pelvic lymph node dissection. METHODS: We conducted a systematic search of MEDLINE, Embase, Web of Science, and the Cochrane Central Register of Controlled Trials through August 30, 2023, to identify randomized and nonrandomized studies comparing RALP with pelvic lymph node dissection with and without PIF. A random effects meta-analysis was then performed to evaluate the associations of PIF with 90-day postoperative outcomes. RESULTS: Five randomized controlled trials (RCTs) and four observational studies, including a total of 2941 patients, were included. The use of PIF was associated with a reduced risk of 90-day symptomatic lymphocele formation after RALP when examining only RCTs (pooled odds ratios [OR] 0.44, 95% CI 0.28-0.69; I2 =3%) and both RCTs and observational studies (OR 0.35, 95% CI 0.22-0.56; I2 =17%). Similarly, use of PIF was associated with a reduced risk of 90-day any lymphocele formation (OR 0.40, 95% CI 0.28-0.56, I2 =39%). There were no statistically significant differences in postoperative complications between the two groups (OR 0.89; 95% CI 0.69-1.14; I2 =20%). CONCLUSION: Use of the PIF is associated with an approximately 50% reduced risk of symptomatic and any lymphocele formation within 90-days of surgery, and it is not associated with an increase in postoperative complications.

Kidney transplant is the best treatment option for patients with end-stage renal disease. It reduces mortality and improves the quality of life. However, kidney transplant presents medical and surgical complications, and one of the most common is the posttransplant lymphocele. Lymphocele complication has an incidence of up to 20% and presents with variable clinical symptoms, which are directly associated with the size and compression effect on the adjacent organs. There are reported risk factors that favor the appearance of lymphocele. Despite known factors, there are more relevant factors (male sex, deceased donor, and corticosteroids) to carry out a stricter follow-up. The treatment of lymphoceles can vary according to the severity of the symptoms, characteristics of the collection, and the patient's clinical status. Despite the high recurrence, percutaneous intervention is the initial approach in this condition. If percutaneous aspiration, drainage, and sclerotherapy are unsuccessful, then open or laparoscopic fenestration can be performed; laparoscopy is the standard of treatment since it is highly effective and has few adverse effects.

ABSTRACT Background: Reports in the literature describe lymphocele formation in up to half of patients following pelvic lymph node dissection (PLND) (1) in robotic-assisted radical prostatectomy (RARP), with 1-2% requiring intervention (2). The advantage of surgical approach is permanent excision of the lymphocele capsule and fewer days with pelvic drains compared to percutaneous drainage. This study aims to describe the step-by-step surgical management of symptomatic lymphoceles using a less invasive robotic platform, the Da Vinci® Single Port (SP). Material and Methods: We describe the technique of lymphocelectomy and marsupialization with the Da Vinci® SP for symptomatic lymphocele. For this study, several treatment modalities for symptomatic lymphoceles were available, including percutaneous drainage, sclerosing agents, and surgical marsupialization. All the data for this study were obtained through the procedure via Da Vinci® SP. Results: Operative time for the case was 84 minutes. Blood loss was 25ml. No intra- or post- operative complications were reported. The patient had his drain removed in under 24 hours after surgery. The mean follow-up period was 7.7 months. There were no complications or lymphocele recurrence. Conclusion: Da Vinci® SP lymphocelectomy is safe and feasible with satisfactory outcomes. The SP enables definitive treatment of the lymphocele sac (3), reducing the number of days with abdominal drains and allows further decrease in surgical invasiveness with fewer incisions and better cosmesis.

Resumen Introducción: El linfocele es una patología que puede ocurrir por la disrupción linfática durante una cirugía, siendo frecuente luego de una linfadenectomía inguinal. Existen diversos enfrentamientos para prevenirlo o minimizarlo, sin embargo, los resultados son inconsistentes. Caso clínico: Reportamos el caso de una mujer, con linfocele recurrente en zona inguinal derecha y linfedema distal de la extremidad secundario a una biopsia ganglionar, tratado exitosamente mediante supermicrocirugía para restaurar el drenaje linfático. La extremidad inferior tenía un exceso de volumen de 7,03%. Se realizaron estudios preoperatorios con linfografía por resonancia magnética y linfografía con verde de indocianina para identificar los vasos linfáticos y realizar anastomosis linfático-venosas (ALV). Se identificaron tres vasos linfáticos aferentes y se realizó una capsulectomía total. Se realizaron tres ALV término-terminales supermicroquirúrgicas en zona inguinal y una ALV distal en pierna. Durante seguimiento no hubo recidiva del linfocele, evidenciándose una reducción del exceso de volumen de la extremidad afectada de un 105,26%. El linfocele inguinal y linfedema pueden ser tratados exitosamente mediante supermicrocirugía, restaurando el flujo linfático de manera fisiológica, evitando la recurrencia de linfocele y mejorando los síntomas del linfedema.
Introduction: Lymphocele may occur after the disruption of lymphatic channels during a surgical procedure. After inguinal lymphadenectomy are very common, and many different approaches have been tried to prevent or minimize the formation of lymphoceles with inconsistent results. Clinical Case: We report a case of a female patient who presented with right recurrent inguinal lymphocele and lower limb lymphedema after lymph-node biopsy that was successfully treated with lymphatic supermicrosurgery restoring the lymph flow. Lower extremity had an excess volume of 7,03% compared to the healthy contralateral limb. Preoperative study with magnetic resonance lymphangiography and indocyanine green lymphography were done to identify intraoperatively lymphocele afferent and distal lymphatic vessels to perform lymphovenous anastomosis (LVA). Three different afferent lymphatics were identified and total capsulectomy was performed. Three end-to- end supermicrosurgical LVA in the groin and one distal LVA on the leg were performed. The surgery was uneventful, and there were no postoperative complications. In the follow-up, no lymphocele was noticed and lymphedema had visibly reduced with a reduction of excess volume of 105.26%. Inguinal lymphocele and lymphedema can be successfully treated with supermicrosurgery since it is a physiological approach to restore the lymphatic flow, in order to avoid lymphocele recurrence and to improve lymphedema symptoms.

Objective: Complications in donation after circulatory death (DCD) kidney transplants (KT) are barely described, while in some urological complications the cause is unknown. The aim of this study is to describe surgical and urological complications and analyze what donation features could be involved. Methods: A prospective, single center study was performed from 2016 to 2019 including all KT from controlled cardiac death donors (cDCD). Results: A total of 86 cDCD KT were included in the study. Recipient BMI, residual urine output (RUO) <500 mL/day, delayed graft function (DGF), and wound complication were related to UTI (p = 0.020, p = 0.008, p = 0.016, and p = 0.004, respectively). Features related to early graft nephrectomy were recipient BMI and recipients with diabetes mellitus (DM) (p = 0.025 and p = 0.036, respectively). DM in recipients was significantly associated with hematuria (p = 0.046). Urinary leak (UL) was associated to vascular complication and ureteral stricture (US) (p = 0.029 both). UL and lymphocele were associated to US (p = 0.029 both). Features related to lymphocele were recipient BMI and US (p = 0.028 and p = 0.029, respectively). History of previous transplant, time from cardiac arrest (CA) to cold flush, and DGF, were associated to wound complication (p = 0.040, p = 0.011 and p = 0.016, respectively). Conclusions: Surgical and urological complications after KT are an important issue to resolve. Our data revealed an association between RUO <500 mL/day, DGF, and wound complication with urinary infection, as well as between recipient DM and hematuria. Recipient BMI and DM were related to early graft nephrectomy (AU)

Objetivos: Describir los diferentes métodos de prevención y resolución de complicaciones y secuelas derivadas de actos quirúrgicos relacionados con el drenaje linfático - linforrea, linfocele y linfedema. Métodos: Revisión de la literatura y comunicación de la experiencia personal de alternativas diagnósticas y terapéuticas con asistencia guiada de imagen. Resultados: Describimos la linfografía mediante cateterización linfática e intranodal con aceite etiodizado (lipiodol) con fines diagnósticos y terapéuticos; la linfografía gammagráfica mediante el uso de isótopos radioactivos con fines diagnósticos; y el uso de colorantes -azul de isosulfan, azul patente, azul de metileno y verde de indocianina- con finalidad diagnóstica y terapeútica. Conclusiones: La linfografía con lipiodol ofrece imágenes bien definidas y es útil en maniobras de radiología intervencionista. Presenta el inconveniente de precisar cateterismo linfático y la imposibilidad de su uso dinámico intraoperatorio. Las técnicas isotópicas son utilizadas con finalidad diagnóstica y en técnicas de biopsia de ganglio centinela. El uso de colorantes ofrece la ventaja de no precisar cateterismo linfático ni de tecnología compleja, precio, disponibilidad, facilidad de uso y de tratarse de una técnica dinámica que permite la identificación intraoperatoria para la resolución de las complicaciones mencionadas
Objectives: To describe the available techniques to prevent and treat complications related with surgery involving lymphatic nodes and drainage:lymphorrea, lymphocele and lymphedema. Methods: Bibliographic review and personal experience communication of different image-assisted techniques in the prevention and management of lymphatic related complications. Results: We describe the conventional lymphography with ethiodized oil contrast (lipiodol) by lymphatic catheterization and intranodal percutaneous puncture used in diagnostics and interventional radiology; the gammagraphic lymphography with radioactive isotopes for diagnostic use; and the utilization of colorants/dyes (patent blue, V-blue, methylene blue, indocyanine green) for diagnostic and therapeutic procedures. Conclusions: Lipiodol lymphography offers well-defined radiologic images and it is useful in interventional radiology procedures. It has the inconvenience of lymphatics catheterization and is not available for surgical dynamic identification of lymphatics. Isotopic techniques are used for diagnostics and sentinel-node procedures.Colorants and dyes have several advantages: no need for catheterization, not expensive technology, price,availability, easy management. It allows the dynamic identification of lymphatics for surgical resolution of lymph-related complications

OBJECTIVE: A number of new techniques have been developed to prevent lymphocele formation after pelvic lymphadenectomy in gynecologic cancers. We assessed whether the electrothermal bipolar vessel sealing device (EBVSD) could decrease the incidence of postoperative lymphocele secondary to pelvic lymphadenectomy. METHODS: A total of 321 patients with gynecologic cancer underwent pelvic lymphadenectomy from 2005 to 2011. Pelvic lymphadenectomy without EBVSD was performed in 134 patients, and pelvic lymphadenectomy with EBVSD was performed in 187 patients. We retrospectively compared the incidence of lymphocele and symptoms between both groups. RESULTS: Four to 8 weeks after operation, 108 cases of lymphocele (34%) were detected by computed tomography scan examination. The incidence of lymphocele after pelvic lymphadenectomy was 56% (75/134) in the tie ligation group, and 18% (33/187) in the EBVSD group. We found a statistically significant difference in the incidence of lymphocele between both groups (p<0.01). To detect the independent risk factor for lymphocele development, we performed multivariate analysis with logistic regression for three variables (device, number of dissected lymph nodes, and operation time). Among these variables, we found a significant difference (p<0.001) for only one device. CONCLUSION: Use of the EBVSD during gynecological cancer operation is useful for preventing the development of lymphocele secondary to pelvic lymphadenectomy.
