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.

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: 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.

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.

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 goal of this study was to evaluate, using definitive diagnostic criteria, the incidence of lymphocyst formation following pelvic lymphadenectomy for gynecological cancer, and to compare rates between the approaches of laparoscopy and laparotomy. METHODS: We retrospectively reviewed the medical records of all patients who underwent pelvic lymphadenectomy for cervical or endometrial cancer between March of 2010 and March of 2016. We defined a lymphocyst as a circumscribed collection of fluid within the pelvic cavity, with a diameter of 2 cm or more, as diagnosed with ultrasound or computed tomography. RESULTS: During the six-year observational period, a pelvic lymphadenectomy was conducted in 196 women with clinical stage I uterine cancer; 90 cases underwent laparoscopy, 106 underwent laparotomy. The minimally invasive laparoscopic group had a lower estimated blood loss (p < 0.01), shorter hospital stay (p < 0.01). Lymphocysts were observed in 14.4% (13/90) of the laparoscopy cases, and in 15.1% (16/106) of the laparotomy cases which means no significant difference of lymphocyst (p = 1.00). The median size of symptomatic lymphocyst was significantly larger in laparotomy group than in laparoscopy group (4.8 cm v.s. 2.8 cm, median) (p = 0.04). Symptomatic lymphocysts were more common in laparotomy [7/90 (7.8%) vs 14/106 (13.2%) (p = 0.253)]. CONCLUSIONS: In a retrospective analysis with a strict diagnostic criteria, we could find no statistical difference in lymphocyst occurrence between laparoscopy and laparotomy. The median size of the lymphocyst was bigger and lymphocyst was likely to be symptomatic in the laparotomy group.

INTRODUCTION: Early endometrial cancer is primarily treated surgically via hysterectomy, adenectomy and, depending on tumor stage and subtype, lymphadenectomy. Systematic lymph node dissection is known to cause surgical complications. The aim of the present study was to investigate morbidity and mortality rates associated with lymphadenectomy in patients with endometrial cancer who underwent surgery in a routine clinical setting. METHODS: We collected data from 232 patients who were operated for endometrial carcinoma between 2006 and 2018 at the University of Lubeck, Germany. Surgical complications were viewed in relation to surgical risk factors. Additionally, a questionnaire concerning long-term lymphatic complications and survival was completed. Survival was compared between patients who underwent lymphadenectomy (group I) and those who did not (group II). RESULTS: Patients in group I needed revision surgery significantly more often due to postoperative complications (such as lymphoceles) compared to those in group II (p = 0.01). The results indicate more serious complications in patients who underwent a systematic lymphadenectomy and in those with lymph node metastases. 15% of patients who underwent a systematic lymphadenectomy had lymph node metastases. Recurrences occurred in 12.5% of cases and were significantly more frequent in patients who had undergone a lymphadenectomy, even if the lymph nodes were negative (p = 0.02). A comparison of survival data during the follow-up period revealed no significant difference. The study highlighted the need for a better preoperative risk stratification and the avoidance of lymphadenectomy for surgical staging alone.

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.

BACKGROUND: Lymphocele is a collection of lymphatic fluid within the body. It is caused by an impairment of lymph drainage and often occurs after a surgical intervention. In this setting conservative treatment is usually ineffective. The aim of this report is to share the outcomes of 11 patients with iatrogenic lymphocele in the thigh area treated by supermicrosurgical lymphovenous anastomosis. PATIENTS AND METHODS: Eleven patients presenting iatrogenic lymphocele in the thigh were referred for surgery after an unsuccessful conservative therapy. Patients' mean age was 56 years old, two males and nine females. All of them presented a moderate-to-severe lymphocele in the medial thigh after a surgical intervention that damaged the rich lymphatic pathway present there. Indocyanine green (ICG) lymphography was always performed to visualize the lymphatic vessels and to make the preoperative marking. RESULTS: All the 11 patients were successfully treated by means of one or more (range: 1-3; mean: 1.5) lymphaticovenous anastomoses without complications. Three of them also received a pedicled sartorius flap for dead space obliteration. All the patients reached full range of motion (ROM) and no recurrences were observed during follow up (range: 6-12 months; mean: 8). Intra-operative ICG lymphography was performed in all cases to check the patency of the anastomoses. CONCLUSIONS: Lymphaticovenous anastomosis confirmed to be a minimally-invasive and effective procedure for the treatment of postsurgical lymphoceles in the leg. For large lymphoceles a muscle flap may be indicated for volume restoration and prevention of recurrences.

BACKGROUND: Sentinel node navigation surgery (SNNS) has been frequently used in early cervical cancer. However, the incidence and potential reduction of lymphatic complications following the removal of the sentinel lymph node remain unknown. Thus, this study aimed to evaluate the occurrence of lymphatic complications post sentinel node navigation surgery in patients with early cervical cancer. METHODS: A total of 167 patients, including 70 and 97 patients who had undergone SNNS and pelvic lymphadenectomy (PLA), respectively, were enrolled in this study. We compared the lymphatic complications (lower extremity lymphedema and pelvic lymphocele) between the SNNS and PLA groups. RESULTS: The median number of sentinel lymph nodes removed was 2 (range: 1-14). Among the 70 patients in the SNNS group, there were 0 (0%) and 3 (4.3%) occurrences of lower extremity lymphedema and pelvic lymphocele, respectively. The occurrences of lower extremity lymphedema and pelvic lymphocele were significantly lower in the SNNS group than in the PLA group, despite circumflex iliac node removal. CONCLUSIONS: The occurrence of lymphatic complications (lower extremity lymphedema and pelvic lymphocele) was significantly lower in the SNNS group than in the PLA group. We found that SNNS, and not PLA, was the best treatment option for preventing the development of lower extremity lymphedema and pelvic lymphocele, despite circumflex iliac node preservation.

Lymphorrhea and lymphocysts are complications that occur after lymph node dissection or biopsy and are difficult to treat. Conventional treatments for lymphocysts are not always effective. For instance, lymphatico-venous anastomosis has a limited treatment efficacy when the cyst wall is thickened, and negative pressure wound therapy is limited by the installation site and longer treatment times. To overcome these individual shortcomings, we aimed to assess whether a combination of both interventions would be effective. In this study, we report the application of a lymphatico-venous anastomosis combined with negative pressure wound therapy for treating bilateral inguinal lymph nodes and pelvic lymph node dissection following treatment of vaginal cancer. Short-term improvements were observed with no recurrence of lymphocysts at 1-year follow-up.

PURPOSE: Despite the introduction of sentinel node biopsy in patients with vulvar cancer, still approximately 50% of all patients have to undergo an inguinofemoral lymphadenectomy. This is associated with a high incidence of postoperative complications, which may be influenced by inguinal drain management. The aim of this study was to investigate the feasibility of a new surgical technique regarding drain management with an inguinoperitoneal drainage. METHODS: A retrospective analysis of 21 vulvar cancer patients with inguinofemoral lymphadenectomy was conducted. A silicone drain was circularly placed with the perforated end in the groin and the other end in the space of Douglas. The removal after 3 months was performed under local anesthesia. All patients were questioned during clinical follow-up regarding their personal experiences with the procedure, the occurrence of complications, and side effects using a clinical questionnaire. RESULTS: In 100% of the patients, the procedure was feasible. Regarding the number of groin punctures due to lymphocyst formation, 15 (71.4%) patients did not need any intervention and 3 (14.3%) patients needed 1-3 punctures. The patient satisfaction with the internal drainage was ranked as good by 17 (81.0%) patients and as moderate by 1 (4.8%) patient. In 3 (14.3%) patients, information about the number of groin punctures and the patient satisfaction were missing. CONCLUSION: Inguinoperitoneal drainage after inguinofemoral lymphadenectomy in vulvar cancer patients is feasible and safe and a patient satisfaction of 81% is promising. For definitive conclusions regarding the efficacy of this technique, further investigations and prospective multicenter trials are needed.

A case with an extremely rare intravenous cystic lesion in the suprahepatic inferior vena cava was reported, which originated from the lymphatic system and had induced Budd-Chiari syndrome. To the best of our knowledge, this is the first report of a benign cystic lesion originating from the wall of a suprahepatic inferior vena cava which results in Budd-Chiari syndrome.

BACKGROUND: Lymphocele and lymphorrhea are frequent complications after lymph node excision. Recurrent lymphoceles and intractable lymphorrhea are particularly difficult to treat conservatively. We describe the outcomes of four patients with recurrent lymphocele and nine patients with persistent lymphorrhea that were treated by supermicrosurgery. METHODS: Four patients with recurrent lymphoceles with a size between 7 and 21 cm and located in the groin (n = 1) or upper leg (n = 3), were referred for surgical treatment between 2013 and 2017 after unsuccessful conservative therapy. Nine patients with lymphorrhea from the groin (n = 7), scrotum (n = 1), or axilla (n = 1) after lymph node or lipoma excision were referred for surgical treatment. Of these, five patients presented with a drainage system and two had a lymphocutaneous fistula. Indocyanine green (ICG) lymphography was used to visualize the lymphatic flow toward the lymphocele, to detect ruptured lymph vessels causing lymphorrhea and for preoperative lymphatic mapping. RESULTS: All 13 patients were successfully treated by one or more (mean: 3, range 1-4) lymphaticovenous anastomoses without perioperative complications. The lymphoceles resolved in all four patients, and no recurrence was recorded during follow-up. The lymphorrhea was cured in all patients by means of lymphaticovenous anastomosis performed distal to the site of leakage. No recurrence was observed during follow-up. The patency of the lymphaticovenous anastomosis was confirmed intraoperatively by means of ICG lymphography in all cases. CONCLUSION: Lymphaticovenous anastomosis is a minimally invasive and effective procedure for the treatment of recurrent lymphocele and persistent lymphorrhea.

The aim of this study is to clarify the incidences of infected pelvic lymphocele (IPL) after robot-assisted radical prostatectomy (RARP). From 2016 to 2017, we evaluated 173 consecutive patients who underwent RARP. The transperitoneal approach was used for the RARPs. Limited lymph node dissection was performed in the pelvic lymphoceles region surrounding the obturator nerve. Patients with IPL were defined as those with infected pelvic lymphoceles classified as Clavien-Dindo (CD) classification system grade II or greater and a fever over 38 degrees Celsius. All other cases were defined as nonIPL. IPL was observed in 5 cases (2.9%) that were classified as CD grade II in 2 cases, IIIa in 2 cases, and IVa in 1 case. The most severe case (CD grade IVa) required temporary dialysis for acute renal failure during conservative treatment. While the dissected lymph nodes in the IPL group were sificantly greater than those in the nonlPL group (20.8 ± 7.1 vs 10.3 ± 6.0, P = 0.0298) and the preoperative prostate specific antigen in the IPL group was significantly higher than that in the nonIPL group (15.6 ± 21.7 ng/ml vs 9.0 ± 6.1 ng/ml, P = 0.0359), there were no significant differences in the other background factors between the two groups. In the multivariate analysis, the number of dissected lymph nodes was an independent predictive factor for IPL. While the incidences of IPL after RARP were low, the number of dissected lymph nodes was related to IPL.

OBJECTIVE: Venous-arterial extracorporeal membrane oxygenation (VA-ECMO) is a well-established therapy for refractory cardiopulmonary failure. Femoral cannulation offers a quick and effective means of providing circulatory support but is not without complication. Inflammation or lymphatic disruption at the site of cannulation can cause the formation of lymphoceles, leading to the patient's discomfort and possibly necessitating intervention. The purpose of this study was to evaluate the incidence of in-hospital lymphocele formation in VA-ECMO patients and to identify predictors for their development. METHODS: We conducted a single-center retrospective review of 192 patients who underwent femoral VA-ECMO insertion and subsequent decannulation from March 2007 to August 2016 for cardiogenic shock. Baseline demographics, risk factors, and cannulation strategies were examined. Groin lymphocele formation was assessed as the primary outcome. RESULTS: Median age was 58 years (interquartile range, 48-67 years) with a median duration of support of 4 days (interquartile range, 2-6 days). Lymphocele formation was identified in 31 patients (16%). Patients who developed lymphoceles were more likely to have post-heart transplantation primary graft dysfunction (PGD) as an indication for ECMO support compared with those who did not (54.2% vs 8%; P < .001). ECMO duration was similar between groups, but lymphocele patients were more likely to have undergone femoral cutdown procedures (68% vs 42%; P = .010). Compared with those PGD patients who did not develop lymphoceles, PGD lymphocele patients had higher rates of diabetes mellitus preoperatively (62% vs 8%; P = .006). Thirteen (42%) patients required surgical incision and drainage, and 4 of these patients (31%) required repeated surgical intervention. CONCLUSIONS: Lymphocele formation is relatively common after femoral VA-ECMO. There was a significantly higher incidence of lymphocele formation in diabetic patients requiring support for PGD after heart transplantation.

OBJECTIVE: To evaluate risk factors, microbiology and management of infected lymphocysts in patients undergoing systemic lymphadenectomy for gynecological cancer. METHODS: Patients with gynecological cancer who developed postoperative lymphocysts after lymphadenectomy were enrolled between January 2009 and June 2017. The clinical data of infected lymphocysts were analyzed and compared with non-infected lymphocysts. Multivariate analysis of risk factors, the microbiology and therapeutic strategies for infected lymphocysts were also evaluated. RESULTS: A total of 115 patients out of 619 developed postoperative lymphocysts, the incidence of infected lymphocysts was 4.36%. Infected lymphocysts were more frequently found in patients with combined pelvic and para aortic lymphadenectomy, higher number of resected pelvic lymph nodes, lower level of postoperative serum hemoglobin and higher proportion of neutropenia. The median diameter of infected lymphocysts was significantly larger than non-infected (71.89 vs 38.47 mm, P < 0.001) and a large size (diameter over 60 mm) was identified as an independent risk factor for infected lymphocysts (OR = 3.933, P = 0.017). The microbiology of infected lymphocysts includes gram-positive cocci, gram-negative bacillus and anaerobic bacteria. Percutaneous catheter drainage was successfully performed in 20 patients with infected lymphocysts. 16 of 19 patients with large lymphoceles received combined antibiobics and PCD therapy and showed clinical remission in all cases. Patients with large size infected lymphocysts who received combined therapy experienced a significantly shorter treatment period and lower recurrent rate than those with only antibiotics (P = 0.046, P = 0.018). CONCLUSIONS: The current study demonstrated that a diameter over 60 mm was an independent risk factor for infected lymphocysts. The predominant bacteria originated from the urogenital or skin flora. The combination of PCD with appropriate antibiotics was a convenient and effective therapeutic strategy resulting in a high success rate.

BACKGROUND: To assess the safety and efficacy of laparoscopic retroperitoneal resection for retroperitoneal lymphatic cysts. METHODS: A retrospective analysis was conducted based on clinical data from eight patients with hydronephrosis caused by retroperitoneal lymphatic cysts. All patients underwent laparoscopic retroperitoneal lymphatic cyst resection and received postoperative follow-up. A follow-up ultrasound was performed postoperatively every 6-12 months to evaluate the recovery of the hydronephrosis. RESULTS: All operations were successful, and their postoperative pathological results revealed lymphatic cyst walls. The operation time ranged from 43 to 88 min (mean: 62 min), with a blood loss of 20 to 130 mL (mean: 76 mL), and the length of hospital stay was 3 to 6 days (mean: 4.5 days). Within the follow-up of 12 to 36 months (mean: 28.5 months), great relief was detected in all eight cases, and no recurrence was found. Moreover, complications such as renal pedicle or renal pelvis injury were not observed. CONCLUSIONS: Laparoscopic retroperitoneal lymphatic cyst resection is an effective treatment for retroperitoneal lymphatic cysts and has the advantages of being minimally invasive, producing less intraoperative blood loss and leading to a quick recovery. This treatment thus deserves further studies.
