RESUMEN
BACKGROUND: Patients with rectal cancer who underwent lateral pelvic node dissection might be at a higher risk of postoperative complications derived from technical complexity. However, little is known regarding the long-term complications after lateral pelvic node dissection. OBJECTIVES: The study aimed to investigate the long-term complications of preoperative chemoradiotherapy, followed by total mesorectal excision with lateral pelvic node dissection for locally advanced rectal cancers. DESIGN: A retrospective analysis of a prospectively collected database. SETTINGS: This study was conducted in a tertiary cancer center. PATIENTS: Patients with rectal cancer who underwent total mesorectal excision with lateral pelvic node dissection after preoperative chemoradiotherapy between 2011 and 2019 were analyzed. All operations were performed via a laparoscopic or robotic approach. MAIN OUTCOME MEASURES: Long-term complications were defined as adverse events that persisted or newly appeared ≥90 days after surgery and could be related to the surgery. RESULTS: A total of 164 patients underwent total mesorectal excision with lateral pelvic node dissection after preoperative chemoradiotherapy. Short-term and long-term complication rates were 36.0% and 36.6%, respectively. Lymphocele was the most common long-term complication (17.7% of patients), and 11.6% had anastomotic leakage with chronic sinus. Of the patients with long-term complications, 20.7% of patients needed readmission for treatment. Of the 29 patients with lymphocele, 13 (41.0%) experienced spontaneous absorption and 11 (37.9%) required surgical or percutaneous catheter drainage or antibiotics use. Multivariate analysis showed pathologic pelvic node metastases ( p = 0.008), and a higher number of unilateral harvested pelvic nodes ( p = 0.001) were significantly associated with long-term complications. At the last follow-up (median duration of 43 months), 15.9% of patients had unresolved complications. LIMITATIONS: The retrospective design. CONCLUSIONS: Patients undergoing lateral pelvic node dissection experienced a higher frequency of long-term complications, but half of them had asymptomatic lymphoceles, most of which resolved spontaneously. However, further efforts should be paid to reduce anticipated complications related to lateral pelvic node dissection. See Video Abstract . COMPLICACIONES A LARGO PLAZO DE LA DISECCIN DE LOS GANGLIOS LIFTICOS PLVICOS LATERALES LAPAROSCPICA O ROBTICA DESPUS DE LA QUIMIORRADIOTERAPIA PREOPERATORIA CONTRA EL CNCER DEL RECTO LOCALMENTE AVANZADO: ANTECEDENTES:Los pacientes con cáncer del recto sometidos a disección ganglionar linfática pélvica lateral podrían tener mayor riesgo de complicaciones postoperatorias derivadas de la complejidad técnica. Sin embargo, se sabe poco sobre las complicaciones a largo plazo después de la disección de los ganglios linfáticos pélvicos laterales.OBJETIVOS:Investigar las complicaciones a largo plazo de la quimiorradioterapia preoperatoria, seguida de escisión mesorrectal total con disección de los ganglios linfáticos pélvicos laterales contra el cáncer de recto localmente avanzado.DISEÑO:Un análisis retrospectivo de una base de datos recopilada prospectivamente.AJUSTES:Este estudio se llevó a cabo en un centro oncológico terciario.PACIENTES:Se analizaron pacientes con cáncer de recto que se sometieron a escisión mesorrectal total con disección de ganglios linfáticos pélvicos laterales después de quimiorradioterapia preoperatoria entre 2011 y 2019. Todas las operaciones se realizaron mediante abordaje laparoscópico o robótico.PRINCIPALES MEDIDAS DE RESULTADO:Las complicaciones a largo plazo se definieron como eventos adversos que persistieron o aparecieron recientemente ≥ 90 días después de la cirugía y podrían estar relacionados con la cirugía.RESULTADOS:Un total de 164 pacientes se sometieron a escisión mesorrectal total con disección de los ganglios linfáticos pélvicos laterales después de quimiorradioterapia preoperatoria. Las tasas de complicaciones a corto y largo plazo fueron del 36,0% y 36,6%, respectivamente. El linfocele fue la complicación a largo plazo más común (17,7% de los pacientes) y el 11,6% tuvo fuga anastomótica con seno crónico. De los pacientes con complicaciones a largo plazo, el 20,7% de los pacientes necesitaron reingreso para recibir tratamiento. De 29 pacientes con linfocele, 13 (41,0%) experimentaron absorción espontánea y 11 (37,9%) requirieron drenaje quirúrgico o percutáneo con catéter o uso de antibióticos. El análisis multivariado mostró metástasis patológicas en los ganglios linfáticos pélvicos ( p = 0,008) y un mayor número de ganglios pélvicos extraídos unilateralmente ( p = 0,001) se asociaron significativamente con complicaciones a largo plazo. En el último seguimiento (mediana de 43 meses), el 15,9% de los pacientes tuvieron complicaciones no resueltas.LIMITACIÓN:El diseño retrospectivo.CONCLUSIONES:Los pacientes sometidos a disección de ganglios pélvicos linfáticos laterales experimentaron una mayor frecuencia de complicaciones a largo plazo, pero la mitad de ellos tuvieron linfoceles asintomáticos, la mayoría de los cuales se resolvieron espontáneamente. Sin embargo, se deben realizar mayores esfuerzos para reducir las complicaciones previstas relacionadas con la disección de los ganglios linfáticos pélvicos laterales.

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.

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.

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.

OBJECTIVES: This study aimed to investigate the possible role of different donor and recipient vessel and ureteral anastomoses on survival and functional outcomes in en bloc kidney transplants. MATERIALS AND METHODS: This retrospective cohort included 99 en bloc kidney transplants performed from December 2005 to March 2022. Recipients were grouped based on donor's vessel (distal [n = 84] or proximal [n = 15] abdominal aorta), recipient's vessel (abdominal aorta [n = 3], external [n = 21], internal [n = 50], or common [n = 25] iliac artery), and ureteral anastomosis (separate [n = 32] or common [n = 67]). Patient and graft survival, complication rates, and estimated glomerular filtration rate trends were compared between groups. RESULTS: Pediatric brain dead donors had a mean age and weight of 37 ± 22 months and 14 ± 4 kg, respectively. Donor and recipient vessel and ureteral anastomoses did not affect overall survival (P = .306, .296, and .225), graft survival (P = .720, .172, and .124), and vascular (P = .347, .689, and .264) and urinary (P = .587, .172, and .385) complication rates. Lymphoceles requiring intervention were significantly more prevalent in the recipient external iliac artery group (P = .008) but were independent of donor vessel and ureteral anastomosis (P = .587 and 1.00). Estimated glomerular filtration rate trend was independentofdonor(P=.921) andrecipient vessel(P=.878 and .536). CONCLUSIONS: We found that different arterial and ureteral anastomoses appear to have comparable outcomes in en bloc kidney transplant with the exception of recipient external iliac artery, which may be slightly inferior because of the relatively higher rate of lymphoceles requiring intervention.

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.

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.

We present the first-in-human robot-assisted microsurgery on a lymphocele in the groin involving a man in his late 60s who had been coping with the condition for 12 months. Despite numerous efforts at conservative treatment and surgical intervention, the lymphocele persisted, leading to a referral to our clinic.Diagnostic techniques, including indocyanine green lymphography and ultrasound, identified one lymphatic vessel draining into the lymphocele. The surgical intervention, conducted with the assistance of a robot and facilitated by the Symani Surgical System (Medical Microinstruments, Calci, Italy), involved a lymphovenous anastomosis and excision of the lymphocele. An end-to-end anastomosis was performed between the lymphatic and venous vessels measuring 1 mm in diameter, using an Ethilon 10-0 suture.The surgery was successful, with no postoperative complications and a prompt recovery. The patient was discharged 3 days postoperatively and exhibited complete recovery at the 14-day follow-up. This case marks the first use of robot-assisted microsurgical lymphovenous anastomosis to address a groin lymphocele, highlighting the benefit of advanced robotic technology in complex lymphatic surgeries.

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.

Introducción: los linfoceles son una complicación poco frecuente en cirugía vascular, pero pueden representarun gran riesgo en pacientes con material protésico. Caso clínico: presentamos el caso de un varón de 82 años sometido hace 43 a radioterapia por un linfoma noHodgkin que presenta un gran linfocele en contacto con material protésico tras una intervención de revasculari-zación urgente. Se realiza tratamiento escleroterápico con espuma de polidocanol al 3% sin conseguir resultadosatisfactorio, por lo que se decide la sustitución del material protésico por autólogo y mioplastia de sartorio. Discusión: a pesar del fracaso con la escleroterapia de la cavidad, en gran medida debido al gran bloqueo linfáti-co crónico, consideramos esta opción la de elección en casos de linfocele por su baja complejidad, invasividad yexcelente relación riesgo/beneficio.(AU)
Background: lymphoceles are a rare complication in vascular surgery but can represent a great risk in patientswith prosthetic material. Case report: we present the case of an 82-year-old man who underwent radiotherapy 43 years ago for non-Hodg-kin lymphoma who presented a large lymphocele in contact with prosthetic material after an urgent revasculari-zation. Sclerotherapy treatment with 3% polidocanol foam was performed without achieving satisfactory resultsfor what we chose replace the prosthetic with autologous material and sartorius myoplasty. Discussion: despite the failure with sclerotherapy of the cavity, largely due to the great chronic lymphatic blockage,we consider this option the choice in cases of lymphocele due to its low complexity, invasiveness and excellentrisk/benefit ratio..(AU)

INTRODUCCIÓN. La enfermedad renal crónica es definida como la pérdida progresiva, permanente e irreversible de la función renal, uno de los tratamientos es el trasplante renal el mismo que aumenta la calidad de vida de los pacientes que presentan esta patología, sin embargo, a pesar de ser uno de las mejores terapias no está exento de complicaciones especialmente las que se presentan posterior al acto quirúrgico ya que afectan al buen funcionamiento del injerto y afecta la supervivencia del mismo. OBJETIVO. Determinar la prevalencia de complicaciones clínicas y quirúrgicas en el postrasplante renal inmediato con el fin de identificar las principales complicaciones que ocasionan mayor deterioro en la función renal a corto plazo. MATERIAL Y MÉTODOS. Estudio Observacional descriptivo transversal, de pacientes trasplantados que se encuentran en seguimiento desde enero del 2015 hasta diciembre del 2018 en el servicio de Trasplante renal del Hospital de Especialidades Carlos Andrade Marín. La muestra será los 211 pacientes trasplantados de donante cadavérico. Los análisis se realizaron con el paquete estadístico IBM SPSS versión 25, para lo cual se empleó estadísticas descriptivas, utilizando tablas y representando los valores absolutos y relativos de las variables cualitativas, así como medidas de tendencia central y de variabilidad para las variables cuantitativas. RESULTADOS. Se estudiaron 193 pacientes trasplantados de los cuales el 49.66% tuvieron complicaciones, de los mismos el 33.16% fueron complicaciones clínicas y 16,5% complicaciones quirúrgicas; de las clínicas la infección de tracto urinario fueron las más prevalentes con 15%, seguida por el rechazo agudo 6,7%, las infecciones por virus poliomavirus BK fueron un porcentaje de 6,2%, la necrosis tubular aguda el 3,16% terminando con el rechazo hiperagudo en el 1,5% y la toxicidad por calcineurínicos 1,04%. Mientras tanto las complicaciones quirúrgicas las urológicas son las más prevalentes 8,8% seguida por las colecciones liquidas con el 6,74% finalmente la trombosis vascular con el 1,04%. CONCLUSIONES. Las complicaciones más prevalentes son las clínicas vs las quirúrgicas, afectando de igual forma la función renal al año sin diferencia estadísticamente significativa.
INTRODUCTION. Chronic kidney disease is defined as the progressive, permanent and irreversible loss of renal function, one of the treatments is renal transplantation, which increases the quality of life of patients with this pathology, however, despite being one of the best therapies, it is not free of complications, especially those that occur after surgery, since they affect the proper functioning of the graft and affect its survival. OBJECTIVE. To determine the prevalence of clinical and surgical complications in immediate post-renal transplantation in order to identify the main complications that cause greater deterioration in short-term renal function. MATERIAL AND METHODS. Cross-sectional descriptive observational study, of transplanted patients under follow-up from January 2015 to December 2018 in the Renal Transplant service of the Hospital de Especialidades Carlos Andrade Marín. The sample will be the 211 cadaveric donor transplanted patients. The analyses were performed with the IBM SPSS version 25 statistical package, for which descriptive statistics were used, using tables and representing the absolute and relative values of qualitative variables, as well as measures of central tendency and variability for quantitative variables. RESULTS. We studied 193 transplanted patients of whom 49.66% had complications, of which 33. Of the clinical complications, urinary tract infection was the most prevalent with 15%, followed by acute rejection 6.7%, polyomavirus BK infections were 6.2%, acute tubular necrosis 3.16%, ending with hyperacute rejection in 1.5% and calcineurin toxicity 1.04%. Meanwhile, urological surgical complications are the most prevalent 8.8% followed by liquid collections with 6.74% and finally vascular thrombosis with 1.04%. CONCLUSIONS. The most prevalent complications are clinical vs. surgical, affecting renal function at one year with no statistically significant difference.
