RESUMO
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.

OBJECTIVES: The purpose of this systematic review and meta-analysis was to evaluate the proportion and risk factors of lymphoceles and symptomatic lymphoceles after PLND in early-stage cervical and early-stage high or high-intermediate risk endometrial cancer. METHODS: Studies reporting on the proportion of lymphocele after PLND were conducted in PubMed, Embase and Cochrane Library. Retrieved studies were screened on title/abstract and full text by two reviewers independently. Quality assessment was conducted using the Newcastle Ottowa Scale and the Cochrane risk-of-bias tool. Proportion of lymphocele and possible risk factors were pooled through random-effects meta-analyses. RESULTS: From the 233 studies retrieved, 24 studies were included. The pooled proportion of lymphocele was 14% and of symptomatic lymphocele was 3%. Routinely performing diagnostics was associated with a significantly higher proportion of lymphocele compared to diagnostics performed on indication (21% versus 4%, p < 0.01). Laparotomic surgical approach led to a significantly higher proportion of lymphoceles than laparoscopic surgical approach (18% versus 7%, p = 0.05). The proportion of lymphocele was significantly higher when >15% of the study population underwent additional paraaortic lymph node dissection (PAOLND) opposed to <15% (15% versus 3%, p < 0.01). A mean number of lymph nodes dissected of <21 resulted in a significantly higher pooled proportion of lymphoceles opposed to when the mean number was 21 or higher (19% versus 5%, p = 0.02). Other risk factors analysed were BMI, lymph node metastasis, adjuvant radiotherapy and follow up. There was no sufficient data to detect significant risk factors for the development of symptomatic lymphoceles. CONCLUSION: The pooled proportion of lymphocele was 14% of which symptomatic lymphoceles occurred in 3%. Significant risk factors for the total proportion of lymphoceles were laparotomic approach, decreased number of lymph nodes dissected and additional PAOLND.

PURPOSE: To investigate the risk factors for postoperative lymphorrhea or/and lymphocele (PLL) in patients undergoing radical prostatectomy (RP). MATERIALS AND METHODS: The clinical data of 606 patients were retrospectively collected. The receiver operating characteristic (ROC) curve was utilized to identify the optimal cutoff value. Multivariable logistic regression analysis was used to screen the independent predictors of PLL. RESULTS: Univariate analysis showed that nine factors differed between the PLL and non-PLL group. Multivariable logistic regression analysis showed that low preoperative fibrinogen level, extraperitoneal surgery, robot-assisted laparoscopic radical prostatectomy (RALRP), and hypoalbuminemia were risk factors and the use of fibrin glue was a protective factor. Correlation analysis showed that the scope of LN dissection (LND) and number of lymph nodes (LNs) dissected were positively correlated with PLL in the extraperitoneal approach, but were not significantly correlated with PLL in the transperitoneal approach. The use of fibrin glue was negatively associated with PLL in the overall procedure and the extraperitoneal approach, but not significantly so in the transperitoneal approach. Comparison of LNs clearance between the two surgical approaches revealed that the extent of LND and number of LNs dissected in the extraperitoneal approach were less than in the transperitoneal approach. CONCLUSION: During RALRP, more attention should be paid to fully clotting the broken end of lymphatic vessels. The use of fibrin glue could reduce the probability of PLL. The extent of LND or number of LNs dissected were positively correlated with PLL in the extraperitoneal approach.

PURPOSE: To assess outcome and predictors of outcome after lymphatic embolization (LE) for early postoperative lymphatic leak after pelvic surgery. MATERIAL AND METHODS: Lymphangiography (LG) procedures performed between May 2015 and February 2020 for postoperative intraperitoneal lymphatic leaks after pelvic surgery were reviewed. Treatment indication was lymphatic drainage of >500 mL/d persisting for >1 week. LE was performed by injecting glue into the iliac lymph node. Fisher exact and Wilcoxon rank-sum tests were used for comparative analysis, and logistic regression was used to assess predictors of outcome. RESULTS: LG was performed in 71 patients. A leak was demonstrated in 69 patients who underwent LE. The mean drainage was 1,329 mL/d ± 773. Catheters were removed in 49 (69.0%) patients after 1 procedure and in 69 (97.2%) patients after a mean of 1.3 procedures. The mean drainage at the time of catheter removal was 157 mL/d ± 100. Failure occurred in 12 (16.9%) cases, including 2 (2.8%) cases of unsuccessful catheter removal and 10 (14.1%) cases of catheter reinsertion owing to recurrent ascites (n = 3) and lymphoceles (n = 7). Older age and drainage of >1,500 mL/d were associated with failure (P = .004). Drainage of >1,500 mL/d was associated with a post-LE catheter dwell time of longer than 1 week (P = .024). Minor adverse events were noted in 4 (5.6%) patients who presented with transient leg swelling. CONCLUSIONS: LE was effective for treating pelvic surgery-related lymphatic leaks. Reintervention may be required. Drainage of >1,500 mL/d was associated with clinical failure and a post-LE catheter dwell time of longer than 1 week.

PURPOSE: To compare the effectiveness of and adverse events related to intranodal glue embolization (IGE) with those of intracavitary sclerotherapy for the treatment of postoperative groin and pelvic lymphatic leaks. MATERIALS AND METHODS: From November 2015 to July 2021, IGE for postoperative pelvic or groin lymphocele or lymphorrhea was performed in 33 patients. From January 2010 to July 2021, 28 patients with postoperative pelvic or groin lymphocele were treated with sclerosis alone. Clinical success was defined as resolution of drainage within 3 weeks of the last intervention performed without recurrence. Patients presenting >1 year after surgery or with <30 days of follow-up were excluded. Patients with lymphorrhea treated with IGE were not statistically compared with those in the sclerosis group because they were not eligible for sclerosis. RESULTS: Clinical success was similar between the groups (lymphocele IGE, 15/18, 83.3%, vs sclerosis, 15/23, 65.2% [P = .29]; lymphorrhea IGE, 8/9, 88.9%). The mean number of interventions performed to successfully treat a lymphocele was significantly higher in the sclerosis group (2.5 for sclerosis vs 1.3 for IGE; P = .003; lymphorrhea IGE, 1.0). The mean time to resolution was significantly longer for sclerosis than for IGE (27 vs 7 days; P = .002; 4 days for lymphorrhea IGE). There were no sclerosis-related adverse events and 2 IGE-related adverse events: (a) 1 case of mild lymphedema and (b) 1 case of nontarget embolization resulting in deep vein thrombosis. CONCLUSIONS: For treatment of postoperative pelvic and groin lymphoceles, IGE results in faster resolution with fewer interventions compared with sclerosis. IGE is also an effective treatment for postoperative groin lymphorrhea.

OBJECTIVES: To evaluate the prevalence of post-operative complications and quality of life (QoL) related to sentinel lymph node (SLN) biopsy vs systematic lymphadenectomy in endometrial cancer. METHODS: A prospective cohort included women with early-stage endometrial carcinoma who underwent lymph node staging, grouped as follows: SLN group (sentinel lymph node only) and SLN+LND group (sentinel lymph node biopsy with addition of systematic lymphadenectomy). The patients had at least 12 months of follow-up, and QoL was assessed by European Organization for Research and Treatment of Cervical Cancer Quality of Life Questionnaire 30 (EORTC-QLQ-C30) and EORTC-QLQ-Cx24. Lymphedema was also assessed by clinical evaluation and perimetry. RESULTS: 152 patients were included: 113 (74.3%) in the SLN group and 39 (25.7%) in the SLN+LND group. Intra-operative surgical complications occurred in 2 (1.3%) cases, and all belonged to SLN+LND group. Patients undergoing SLN+LND had higher overall complication rates than those undergoing SLN alone (33.3% vs 14.2%; p=0.011), even after adjusting for confound factors (OR=3.45, 95% CI 1.40 to 8.47; p=0.007). The SLN+LND group had longer surgical time (p=0.001) and need for admission to the intensive care unit (p=0.001). Moreover, the incidence of lymphocele was found in eight cases in the SLN+LND group (0 vs 20.5%; p<0.001). There were no differences in lymphedema rate after clinical evaluation and perimetry. However, the lymphedema score was highest when lymphedema was reported by clinical examination at 6 months (30.1 vs 7.8; p<0.001) and at 12 months (36.3 vs 6.0; p<0.001). Regarding the overall assessment of QoL, there was no difference between groups at 12 months of follow-up. CONCLUSIONS: There was a higher overall rate of complications for the group undergoing systematic lymphadenectomy, as well as higher rates of lymphocele and lymphedema according to the symptom score. No difference was found in overall QoL between SLN and SLN+LND groups.

OBJECTIVE: The purpose of this network meta-analysis was to compare the effectiveness and adverse effects of limited, standard, extended, and super-extended pelvic lymph node dissection (PLND) following radical prostatectomy. METHODS: This study followed the PRISMA 2020 statement. Clinical trials were searched from three electronic databases, including PubMed, the Cochrane Library, and Embase from the database's inception to April 5, 2022. The lymph node-positive rate, biochemical recurrence-free rate, lymphocele rate, thromboembolic rate, and overall complication rate were compared by meta-analysis. Data analyses were performed using R software based on the Bayesian framework. RESULTS: Sixteen studies involving 15,269 patients were included. All 16 studies compared the lymph node-positive rate; 5 studies compared the biochemical recurrence-free rate; 10 studies compared the lymphocele rate; 6 studies compared the thromboembolic rate, and 9 studies compared the overall complication rate. According to Bayesian analysis, the lymph node-positive rate, lymphocele rate, and overall complication rate were significantly associated with the extension of the PLND range. The limited, extended, and super-extended PLND templates showed a similar but lower biochemical recurrence-free rate and a higher thromboembolic rate than the standard template. CONCLUSIONS: The extension of the PLND range is associated with an elevated lymph node-positive rate; however, it does not improve the biochemical recurrence-free rate and correlates with an increased risk of complications, especially lymphocele. The selection of the PLND range in clinical practice should consider the oncological risk and adverse effects. TRIAL REGISTRATION: PROSPERO (CRD42022301759).

Subacute groin complications associated with extracorporeal membrane oxygenation (ECMO) cannulation are well recognized, yet their effects on clinical outcomes remain unknown. This single-center, retrospective study reviewed all patients receiving venoarterial ECMO from 01/2017 to 02/2020. Cohorts analyzed included transplanted patients (TPs) and non-transplanted patients (N-TPs) who did or did not develop ECMO-related subacute groin complications. Standard descriptive statistics were used for comparisons. Logistic regressions identified associated risk factors. Overall, 82/367 (22.3%) ECMO patients developed subacute groin complications, including 25/82 (30.5%) seromas/lymphoceles, 32/82 (39.0%) hematomas, 18/82 (22.0%) infections, and 7/82 (8.5%) non-specified collections. Of these, 20/82 (24.4%) underwent surgical interventions, most of which were muscle flaps (14/20, 70.0%). TPs had a higher incidence of subacute groin complications than N-TPs (14/28, 50.0% vs. 68/339, 20.1%, P = 0.001). Seromas/lymphoceles more often developed in TPs than N-TPs (10/14, 71.4% vs. 15/68, 22.1%, P = 0.001). Most patients with subacute groin complications survived to discharge (60/68, 88.2%). N-TPs who developed subacute groin complications had longer post-ECMO lengths of stay than those who did not (34 days, IQR 16-53 days vs. 17 days, IQR 8-34 days, P < 0.001). Post-ECMO length of stay was also longer among patients who underwent related surgical interventions compared to those who did not (50 days, IQR 35-67 days vs. 29 days, IQR 16-49 days, P = 0.007). Transplantation was the strongest risk factor for developing subacute groin complications (OR 3.91, CI95% 1.52-10.04, P = 0.005). Subacute groin complications and related surgical interventions are common after ECMO cannulation and are associated with longer hospital stays. When surgical management is warranted, muscle flaps may reduce lengths of stay compared to other surgical interventions.

AIM: To study the efficacy of octreotide to reduce lymphorrhea and prevent lymphocele after pelvic lymph node excision in gynecological malignancies. METHODS: Patients with more than 200 mL of lymph drained per day until postoperative day 3 after pelvic lymph node excision were enrolled. Of the 75 patients, 36 were managed by conservative methods without the injection of octreotide, and the other 39 patients were treated with the injection of octreotide. The treated group was injected with 0.1 mg octreotide q8h for 5 days, starting on postoperative day 3. The drainage tube was removed when the amount of drained lymph decreased to 100 mL per day. The age, BMI, operation time, removed lymph nodes, amount of lymph, duration of drain placement, proportion of patients with lymphocele and complications between these two group were compared. RESULTS: The total and mean daily amount of lymph produced per patient was significantly lower in the octreotide-treated group than in the untreated group. The duration of drain placement was shorter in the octreotide group than in the untreated group. The proportion of patients with lymphocele in the treatment group was lower than that in the untreated group. CONCLUSIONS: The injection of octreotide is effective to reduce lymphorrhea and prevent lymphocele after pelvic lymph node excision in gynecological malignancies.

OBJECTIVES: To assess the necessity of prophylactic drain placement in retroperitoneal laparoscopic nephroureterectomy with open distal ureterectomy for upper tract urothelial cancer. METHODS: Between July 2011 and March 2021, 200 patients with localized clinical Tis-T3 upper urinary tract urothelial carcinoma underwent laparoscopic nephroureterectomy with open distal ureterectomy. After removing the specimen, drainage tubes were placed on the renal beds and/or in the retrovesical spaces. Drain tubes were omitted for most patients after 2017. We compared the postoperative outcomes between the patients with drain placement (D+ group) and without drain placement (D- group) using propensity score matching. RESULTS: A total of 164 patients (90 in the D+ group and 74 in the D- group) were enrolled, and matched pairs of 108 patients were analyzed. There was no significant difference in the incidence of complications according to Clavien-Dindo grade in the two groups after the propensity score matching. There was no significant difference in the incidence of postoperative lymphocele (n = 5 vs. 9, p = 0.395) and symptomatic lymphocele (n = 1 vs. 1, p = 1) between the two groups. The length of hospital stay was significantly shorter in the D- group (11 vs. 8 days, p < 0.0001). CONCLUSIONS: We found that omitting the drainage tube after laparoscopic radical nephroureterectomy did not increase postoperative complications or lymphocele and shortened the post-hospital stay.

BACKGROUND: Large locoregional defects affecting lymphatic-rich regions may be subject to serious lymphatic complications, such as lymphedema and recurrent lymphocele. In the last few years, a demeaning volume reconstruction combined with lymph flow restoration showed to effectively reduce their incidences. The purpose of this report is to present the preliminary results of the use of pedicled SCIP flap with LVA between the recipient site lymphatic vessels and flap superficial vein for reconstruction of soft tissue defect and creation of lymph flow-through to reduce lymphatic complications. PATIENTS AND METHODS: Between 2018 and 2020, 4 patients (2 males and 2 females), with a mean age of 56.5 years (ranging 42-76 years), presented a soft tissue defect with lymphatic drainage damage which was reconstructed by resorting to pedicled SCIP flap. Causes of the defect were tumoral surgical excision in 3 cases and severe trauma in 1 case. The defects were located in the medial thigh in 2 cases and groin area in 2 cases, with sizes ranging from 5 × 19 cm to 8 × 22 cm. The SCIP flap was raised by paying attention to preserve some suitable veins at the distal edge of the skin paddle. The flap was then turned 180 degrees and inset in order to match the direction of the recipient's lymphatic vessels. One or more LVAs were performed between the recipient site damaged lymphatics and a superficial flap's vein. RESULTS: The sizes of flaps ranged from 5 × 19 cm to 8 × 22 cm. The mean number of LVAs was 2.2 (ranging from 1 to 3). A minor post-operative complication was encountered (small infected seroma) in 1 case, which was conservatively managed. No secondary procedures were required. In all cases complete range of motion (ROM) of the hip joint and wound coverage at both donor and recipient site were achieved. The mean follow-up was 8 months (ranging 7-10 months). No signs of lymphedema and lymphocele were reported over this time. CONCLUSIONS: The pedicled SCIP flap with LVA between the recipient site lymphatic vessels and flap superficial vein may provide a solution for inguinal and upper thigh defects reconstructions that requires a lymphatic drainage restoration. Its superficial veins may be exploited to perform LVAs at recipient site, thus reducing the lymphatic complications in these delicate regions.

INTRODUCTION: The primary morbidities of inguinal and axillary systematic nodal dissection are lymphatic fistulas and seromas. Intraoperative fluorescence imaging-guided sealing of lymph vessels may prevent these postoperative complications. METHODS: Indocyanine dye was injected intracutaneously into the distal limb before the beginning of the lymphadenectomy. Systematic nodal dissection was performed according to standard protocols. Near-infrared imaging was applied throughout the procedure and real-time fluorescence-guided lymph vessel sealing was performed. RESULTS: Fluorescence-guided lymph vessel sealing was implemented in three patients undergoing axillary systematic lymph node dissection. No adverse events occurred following fluorescence dye injection. All patients could be discharged free of wound complications. CONCLUSION: Fluorescence-guided lymph vessel sealing might be a promising new technique for preventing lymphatic fistulas and lymphocele after systematic lymphadenectomy.

BACKGROUND: We aim to show pelvic lymphocele (PL) rates in patients who were operated for endometrial cancer (EC) and underwent systematic paraaortic bilateral pelvic lymph node dissection (PABPLND) with advanced bipolar vessel sealing device (ABVSD). METHODS: The medical files of all patients who underwent open surgery for EC between January 2017 and December 2021 were retrospectively analyzed. One hundred three patients who operated with the diagnosis of high-intermediate and high-risk endometrial cancer were included. Systematic PABPLND was performed with total abdominal hysterectomy with or without bilateral salpingo-oophorectomy during surgery to all patients. All operations were performed by same three surgeons who were expert in their field. While the lymph packages were removed during surgical dissection, the distal afferent and proximal efferent lymphatic channels were sealed with LigaSure™ blunt tip sealer/divider (Medtronic, Covidien, USA). The patients were scanned with computed tomography (CT) between 8 and 12 weeks postoperatively. Lymphocele diagnosis was confirmed by radiologists and largest diameter was recorded. Clinical-pathological findings of all patients were recorded. RESULTS: Mean age and body mass index (BMI) of all participants were 58.6 ±10.2 years and 28.1± 5.6 kg/m2 . The most histopathological findings were endometrioid type (84.5%) and grade 2 (44.2%) ECs. The pelvic lymphocele (PL) was detected with CT in 24 of 103 patients at 8 to 12 weeks postoperatively. Only two PL patients were symptomatic. The first patient had symptoms of pelvic fullness and compression while the second patient had infected image. PL was located to right pelvic area in first case while the second was located on the vaginal cuff. DISCUSSION: The dissection and sealing of major lymph vessels were achieved during the removal of all lymph packages with LigaSure™ blunt tip laparoscopic sealer/divider. The use of advanced bipolar systems can reduce the formation of PL in lymph node dissection in endometrial cancer.

PURPOSE: The purpose of this study was to investigate the effect of a surgically constructed bilateral peritoneal flap (PIF) as an adjunct to robot-assisted radical prostatectomy (RARP) and pelvic lymph node dissection (PLND) on the incidence of lymphoceles. MATERIALS AND METHODS: A total of 530 men with localized prostate cancer underwent a RARP with bilateral extended standardized PLND in a prospective randomized controlled trial. In group A, a PIF was created by suturing the margins of the bladder peritoneum to the ipsilateral endopelvic fascia at 2 points on each side. In group B, no PIF was created. The patients were followed 30 and 90 days after the surgery to assess the incidence, extent and treatment of lymphoceles. RESULTS: Lymphoceles occurred in 22% of group A patients and 33% of group B patients (p=0.008). Symptomatic lymphoceles were observed in 3.3% of group A patients and 8.1% of group B patients (p=0.027). Lymphoceles requiring intervention occurred significantly less frequently in group A patients (1.3%) than in group B patients (6.8%, p=0.002). The median lymphocele size was 4.3 cm in group A and 5.0 cm in group B (p=0.055). No statistically significant differences were observed in minor or major complications unrelated to lymphocele, blood loss, or surgical time between groups A and B. CONCLUSIONS: Bilateral PIFs in conjunction with RARP and PLND significantly reduce the total incidence of lymphoceles, the frequency of symptomatic lymphoceles and the rate of associated secondary interventions.
