Laparoscopic treatment of lymphoceles in patients after renal transplantation

Postoperative lymphoceles after renal transplantation appear in up to 18% of patients, followed by individual indisposition, pain or impaired graft function. Therapeutic options are percutaneous drainage, needle aspiration with sclerosing therapy, or internal surgical drainage by conventional or laparoscopic approach. The laparoscopic procedure offers short hospitalisation time and quick postoperative recovery. From 1993 to 1997, 16 patients underwent laparoscopic fenestration of a post-renal transplant lymphocele, and were presented in a retrospective analysis. Three patients have had previous abdominal surgery. Following preoperative ultrasound and CT scan, 16 patients underwent laparoscopic drainage after drainage and staining of the lymphocele with methylene blue. No conversion was necessary. Mean operation time was 42 min, no intraoperative complications were seen. Oral nutrition and immunosuppression were continued on the day of surgery, and patients were discharged between the 2nd and 5th (median hospital stay 3.3 d) day after surgery. No recurrence was evident in a follow-up time of 15-54 months (median 31.4 months). Renal function remained unchanged in all patients postoperatively.     

Fibrin Glue Injections: A Minimally Invasive and Cost‐Effective Treatment for Post–Renal Transplant Lymphoceles and Lymph Fistulas

Pelvic lymphoceles/lymph fistulas are commonly observed after kidney allotransplantation, especially when the kidney is placed in a retroperitoneal position. While the majority are <5 cm in diameter and resolve without intervention, some may continue to enlarge, and cause local or systemic symptoms or graft dysfunction. Among 1662 recipients of both living and deceased donor kidney transplants between January 2003 and July 2014, we found 46 (2.7%) patients with symptomatic lymphoceles requiring intervention. We studied the clinical outcomes and charges for three treatment modalities including open surgical drainage (22), laparoscopic surgical drainage (11), and percutaneous fibrin glue injections into the drained lymphocele cavity (13). The patient demographics and clinical characteristics were comparable for each treatment group, although maintenance immunosuppressive drugs differed by era. We found fibrin glue injections resulted in significantly lower (p = 0.04) rates of recurrence (1; 7.7%) than either laparoscopic (6; 54%) or open surgical drainage (6; 27.3%). In addition, fibrin glue injections generated significantly (p < 0.001) lower median ($4559) charges compared to either laparoscopic ($26 330) or open surgical drainage ($23 758). Fibrin glue treatment has the advantage of being an outpatient procedure, performed with the patient under local anesthesia, and does not incur the expense of an operative procedure or hospital admission associated with laparoscopic or open surgery.     

Management of lymphoceles after renal transplantation: laparoscopic versus open drainage

PURPOSE: Laparoscopic surgery has become widely accepted for the treatment of lymphoceles following kidney transplantation. In this single center study we retrospectively reviewed our results of the surgical management of post-transplant lymphoceles, assessing indication and outcome of laparoscopic versus open drainage. MATERIALS AND METHODS: The records of 60 patients who underwent surgical treatment for a symptomatic lymphocele following kidney transplantation or combined kidney/pancreas transplantation were retrospectively reviewed. RESULTS: Between 1995 and 2002, 1,836 patients received a kidney transplant at the University of California San Francisco. In 60 patients (3.3%) a symptomatic lymphocele developed and either laparoscopic (20) or open drainage (40) was completed. The conversion rate from laparoscopic to open drainage was 16.5%. The most common indications for open lymphocele drainage were noninfectious wound complications (13 patients) and a high risk of vessel or ureter injury (8) due to proximity of the lymphocele to hilar structures. Additional surgery on the graft was required in 5 patients. Intraoperative blood loss was significantly lower in the laparoscopy group. Median hospital stay was 1 day in the laparoscopy group versus 4 days in the open drainage group. No perioperative complications were observed in either group. After a median followup of 38 months, 2 patients in each treatment group had a symptomatic recurrence. CONCLUSIONS: Although both surgical approaches are safe and effective, laparoscopic drainage should remain the method of choice for the treatment of post-transplant lymphocele. However, open drainage should be performed in patients with wound complications and in those with a small lymphocele adjacent to vital renal structures.     

Laparoscopic treatment of post renal transplant lymphoceles

Background: Traditionally, a post transplant lymphocele (PTL) is drained by widely opening the wall connecting the lymphocele cavity to the intraperitoneal space via laparotomy. We hypothesize that laparoscopic techniques can be effectively used for the treatment of PTL.Methods: Patients requiring intervention for PTL between 1993 and 2002 were identified via a retrospective review. Results of drainage via laparotomy and laparoscopy were compared.Results: During the study period 685 renal transplants (391 cadaveric, 294 living) were performed. The incidence of lymphocele was 5% [34/685 (36 cases)]. The indications for surgical drainage were local symptoms (69%), graft dysfunction (14%), or both (17%). The mean time to surgical therapy was 4.9 months. Laparoscopic drainage was performed in 25 patients (74%) and open drainage in 9 patients (26%). Open procedures were performed in cases for: previous abdominal surgery (5), undesirable lymphocele characteristics or location (2), or with concomitant open procedures (3). There were no conversions or operative complications in either group. There was no difference in operative time for the laparoscopic group vs the open group (108 ± 6 vs 123 ± 18 min, p = 0.8). Hospital stay was significantly shorter for the laparoscopic group (1.7 ± 0.8 vs 3.8 ± 1.0, p = 0.0007), with 88% of laparoscopic patients being either overnight admissions or same day surgery. Two patients (5%) developed symptomatic recurrences requiring reoperation [1 laparoscopic (4%), 1 open (10%)].Conclusions: Laparoscopic fenestration of a peritransplant lymphocele is a safe and effective treatment. The large majority of patients treated with laparoscopic fenestration were discharged within one day of surgery. Unless contraindications exist, laparoscopy should be considered first-line therapy for the surgical treatment of posttransplant lymphocele.     

Laparoscopic treatment of symptomatic lymphoceles after kidney transplantation

BACKGROUND: The incidence of lymphocele after kidney transplantation ranges from 0.6% to 18%. This study examines the use of laparoscopic ultrasound for the location of lymphoceles during laparoscopic drainage. METHODS: Between July 1993 and October 1998, we performed 147 kidney transplants. A symptomatic lymphocele was observed in 19 patients (12.9%). All of these patients underwent peritoneal laparoscopic fenestration of the lymphocele. The graft, kidney hilum, ureter, iliac vessels, and lymphoceles were identified by laparoscopic ultrasound. RESULTS: All but one patient were discharged within 24 h. One recurrence (5.2%), which was successfully treated by laparoscopy, was observed at a mean follow-up of 15.5 months. We had one complication (5.2 %)-a left hydrocele that occurred 2 days after drainage of a lymphocele located in the left iliac fossa. CONCLUSIONS: Laparoscopic peritoneal drainage of posttransplant lymphoceles shares the well known advantages of laparoscopy. Furthermore, laparoscopic ultrasound is a useful tool that allows the recognition of anatomical structures and decreases the risk of iatrogenic lesions.     

Improvement of post-transplant lymphocele treatment in the laparoscopic era

Post-transplant lymphoceles are a common problem after renal transplantation, often inflicting the graft or adjacent iliac veins. Since 1991, there have been many reports on laparoscopic fenestration as the treatment of choice, but no larger series has been presented. At our department, 63 laparoscopic procedures were performed between 1993 and 2001 among 1502 renal graft recipients. The laparoscopic operation time, conversion rate, hospital stay, and complications have all decreased progessively. Duration of hospital stay and convalescence was markedly longer in patients treated with conventional open surgery (27 patients). Rejections, CMV disease, and post-transplant reoperations seem to have an increased incidence in the lymphocele population. According to our experience, laparoscopic fenestration is the superior treatment for symptomatic lymphoceles, allowing minimal trauma and fast recovery. Our series suggests that the rate of complications/graft injury decreases progressively with experience. Laparoscopic ultrasound seems useful in difficult cases. Prophylactic measures should be emphasised at the time of transplantation and reoperations.     

Laparoscopic peritoneal drainage of symptomatic lymphoceles after pelvic lymph node dissection using methylene blue instillation

BACKGROUND: Lymphoceles are frequent complications of pelvic lymph node dissection. While small lymphoceles often remain undetected, larger ones can cause complications and require further treatment, e.g. percutaneous tube drainage alone or in combination with sclerotherapy. However, recurrence rates are considerable, and long-lasting drainage may lead to infection, prolonged hospitalization, and as a consequence, increased overall costs. We report the results of a simplified laparoscopic approach to drain lymphoceles after radical prostatectomy plus pelvic lymphadenectomy using methylene blue instillation. METHODS: 13 patients with large symptomatic pelvic/retroperitoneal lymphoceles refractory to percutaneous tube drainage and doxycycline sclerotherapy received a laparoscopic transperitoneal marsupialization following instillation of a sterile diluted methylene blue solution into the drained cavity to refill and mark the lymphocele. RESULTS: All lymphoceles were sterile and ranged in size from 7 x 6 x 4 to 15 x 12 x 6 cm. Clinical symptoms included lower abdominal swelling, tenderness in the iliac fossa, ipsilateral lymphedema, deep venous thrombosis, wound fistula, and hydronephrosis due to ureteral obstruction. After methylene blue instillation, the lymphoceles were easily identified and opened. Median total operative time was 50 (range 25-70) min; blood loss was negligible. There was one complication in the form of a metachronous infection in the operating field and no relapses. Patients were discharged 1-5 (median 3) days after the surgical procedure. CONCLUSIONS: Laparoscopic peritoneal drainage requires greater operative skill than percutaneous approaches. However, the instillation of a methylene blue solution simplifies this procedure as the extent and location of the lymphoceles can be precisely identified during laparoscopy. We recommend early application of laparoscopic peritoneal drainage following methylene blue instillation for patients with sterile lymphoceles after pelvic lymph node dissection in whom temporary percutaneous drainage and sclerotherapy failed to resolve the lymph fluid collection.     

The outcomes of treatment and the etiology of lymphoceles with a focus on hemostasis in kidney recipients: a preliminary report

Background

The etiopathogenesis of lymphoceles remains incompletely understood. The aim of our work was to analyze the perturbations of blood coagulation process for their possible impact on the etiology of lymphoceles. Additionally we performed an evaluation of the incidence and effectiveness of treatment methods for lymphoceles.

Materials and methods

During 2004 to 2010, we performed 242 kidney transplantations in 92 female and 150 male patients. The hemostatic parameters included concentrations of: antithrombin, plasminogen, thrombin/antithrombin complexes (TAT), prothrombin products F1+2 (F1+2), d-dimers, and plasmin/antiplasmin complexes.

Results

At 7 years follow-up 27 (11%) recipients had developed symptomatic lymphoceles, namely abdominal discomfort, a palpable mess in the lower abdomen, arterial hypertension, infection of the operative site with fever, lymphorrhoea with surgical wound dehiscence, decreased diurnal urine output with an elevated plasma creatinine, voiding problems of urgency and vesical tenesmus, and/or symptoms of deep vein thrombosis. We applied the following methods of treatment aspiration alone, percutaneous drainage, laparoscopic fenestration or open surgery. In two only patients did perform open surgery. Since 2008 we have not performed an aspiration alone because of high rate of recurrence (almost 100%) and abandoned open surgery in favor of a laparoscopic approach. Our minimally invasive surgery includes percutaneous drainage guided by ultrasound and a laparoscopic procedure with 100% effectiveness. The examined hemostatic parameters revealed decreased concentrations of TAT complexes and F1+2 in subjects with lymphocele showing positive predictive values of 33% and 41% respectively. The negative predictive values for TAT complexes and F1+2 were 14% and 10%, respectively, suggesting decreased blood coagulation activity among effected recipients. Altered blood coagulation processes may explain some aspects of the disturbances of postoperative obliteration of damaged lymphatic vessels and formation of pathological lymph collection afterward.

Conclusions

Perturbations of blood coagulation may be one cause for a lymphocele.     

Laparoscopic management of large retroperitoneal lymphoceles complicating aortic surgery

Retroperitoneal lymphocele is a rare but debilitating complication of aortic replacement with synthetic graft. The only effective treatment reported to date is surgical reexploration and ligation of leaking lymphatics. This report illustrates the successful management of two patients with large retroperitoneal lymphoceles formed after aortic surgery using laparoscopic techniques. The available literature is reviewed. Laparoscopic fenestration of the lymphocele and laparoscopically assisted ligation of the leaking lymphatics combined with internal drainage resulted in long-term relief of compression symptoms, as observed, respectively, over the 5-year and 3-month follow-up periods. Percutaneous catheter drainage before laparoscopic management was unsuccessful in both cases. In addition, the unique presentation of a large retroperitoneal lymphocele with intestinal obstruction is reported, and currently available treatment options are discussed.

Symptomatic lymphoceles after kidney transplantation – multivariate analysis of risk factors and outcome after laparoscopic fenestration

Ulrich F, Niedzwiecki S, Fikatas P, Nebrig M, Schmidt SC, Kohler S, Weiss S, Schumacher G, Pascher A, Reinke P, Tullius SG, Pratschke J. Symptomatic lymphoceles after kidney transplantation – multivariate analysis of risk factors and outcome after laparoscopic fenestration.
Clin Transplant 2009 DOI: 10.1111/j.1399‐0012.2009.01073.x
© 2009 John Wiley & Sons A/S. Abstract: Lymphocele formation is a common complication after kidney transplantation, and laparoscopic surgery has become a widely accepted treatment option. The aim of this retrospective study was to analyze the risk factors of lymphocele development and to assess the treatment outcome after laparoscopic fenestration. We analyzed 426 renal allograft recipients operated between 2002 and 2006 receiving triple immunosuppression with calcineurin inhibitors. The incidence of lymphocele was 9.9%, while 24 (5.6%) patients with symptomatic lymphoceles required laparoscopic surgery. Serum creatinine at diagnosis was significantly higher in patients with lymphoceles treated surgically (3.2 ± 0.7 vs. 1.7 ± 0.6 mg/dL; p < 0.001). After successful laparoscopic intervention, creatinine concentrations recovered until discharge and were comparable to other patients (1.6 ± 0.5 vs. 1.5 ± 0.5 mg/dL; p = NS). While we observed a significant association of lymphocele formation with diabetes, tacrolimus therapy, and acute rejection in univariate testing, only diabetes remained a significant factor after multivariate analysis. Laparoscopic fenestration proved to be a safe and efficient method without any associated mortality and a low recurrence rate of 8.3% (n = 2). We conclude that diabetes is an independent risk factor for lymphocele development, and laparoscopic fenestration should be the treatment of choice for larger and symptomatic lymphoceles, as it is safe and offers a low recurrence rate.     

Lymphozele nach radikaler retropubischer Prostatektomie

Lymphoceles represent a common complication following pelvic lymphadenectomy and radical retropubic prostatectomy. Relevant articles published in the last 25 years and our own results based on a prospective study were taken as the basis for a treatment algorithm for lymphoceles after radical prostatectomy. The type of intervention depends on the clinical situation of the patient. Symptomatic lymphoceles can be managed initially by percutaneous aspiration with or without instillation of sclerosing agents. However, lymphocele recurrence rates are high. Symptomatic, sterile lymphoceles appear to be ideally suited for drainage by laparoscopic techniques. This method is effective, usually immediately definitive, results in minimal patient morbidity, and allows for a more rapid recovery. Infected lymphoceles require percutaneous or open surgical drainage. Laparoscopic marsupialization of symptomatic lymphoceles after pelvic lymphadenectomy for prostate cancer appears to be safe and effective. Because of the minimal postoperative morbidity, rapid convalescence, and low recurrence rate, laparoscopic lymphadenectomy should be considered as a first-line treatment for symptomatic, uninfected sterile lymphoceles.     

Laparoscopic fenestration of posttransplant lymphoceles

BACKGROUND: A lymphocele is a common finding after renal transplantation and occurs in up to 20% of patients. The majority of patients are asymptomatic. However, once a lymphocele has become symptomatic (e.g., through transplant dysfunction) this condition has to be treated. We report our 9-year experience with laparoscopic lymphocele fenestration and discuss the current management options for posttransplant lymphoceles. METHODS: Since 1993, 19 patients (11 males and 8 females; median age 56 years, range 22-68 years) of a total of 31 patients with a symptomatic posttransplant lymphocele have undergone laparoscopic fenestration of their lymphocele at a median of 66 days (range, 19-111 days) following successful renal transplantation in our department. As a first-line treatment, a percutaneous pigtail drainage catheter was inserted in all patients. In case of failure in resolving the fluid collection, the next step included sclerotherapy by instillation of tetracycline or ethanol into the lymphocele cavity in some cases. In patients with a persistent lymphocele, a laparoscopic lymphocele fenestration via a transabdominal approach was undertaken to achieve adequate drainage. RESULTS: Primary laparoscopic lymphocele fenestration was successful in all except two patients, who required a conversion. The median operating time was 36 min (range, 20-70 min). Following the procedure, renal transplant function remained stable or returned to individually normal levels in all patients. Median duration of hospital stay was 4 days (range, 1-13 days). At median follow-up of 27 months, all patients were alive with a functioning transplant. CONCLUSIONS: Laparoscopic lymphocele fenestration is reserved for patients in whom temporary drainage with or without sclerotherapy failed to resolve the fluid collection. In these cases the laparoscopic approach offers obvious technical and clinical advantages compared to open operative techniques.     

The optimal treatment of lymphoceles following renal transplantation

Lymphoceles are well-recognized complications following kidney transplantation. The authors describe their experience with the treatment of eight clinically significant lymphoceles (incidence 2.7%). In seven patients percutaneous needle aspiration was attempted, often repeatedly, both for diagnostic and therapeutic purposes. In all of the patients the lymphocele recurred within days and internal marsupialization was therefore performed, in the last two patients utilizing minimal access surgery through laparoscopy. There were no postoperative complications or signs of a recurrence of the lymphocele. Patients following the laparoscopic marsupialization had a much briefer hospital stay and postoperative convalescence. Our results confirm that internal marsupialization is the procedure of choice for most post-transplant lymphoceles. Internal marsupialization through laparoscopy should be used in patients who meet the standard criteria for laparoscopy.This is a United States government work. There are no restrictions in its use.

The laparoscopic management of post-transplant lymphocele

Background: The management of lymphocele in patients following kidney (KT) and kidney pancreas (KPT) transplants is evolving. Open surgery has been the traditional treatment, but some authors have advocated laparoscopic drainage in selected patients. Methods: We retrospectively reviewed our results in lymphocele treatment since developing a laparoscopic program at our institution. Results: Between May 1994 and June 1995, 186 KTs and 48 KPTs were performed, and 1,354 patients are currently being followed. Eight patients developed symptomatic lymphoceles an average of 26 months (range 4–59) following 6 KTs and 2 KPTs. All patients diagnosed were successfully drained laparoscopically, with no conversions to open surgery. Laparoscopic ultrasound was used to help with localization of the fluid collection. Operative time averaged 59 min, median hospital stay was 1 day (range 1–4), and there were no perioperative complications. Follow-up imaging was obtained on six patients, 3–16 months following their procedures, and no recurrences were noted. A review of the literature demonstrates a 5.3% rate of major complications and a 7% incidence of lymphocele recurrence. Conclusions: Intraoperative laparoscopic ultrasound can help localize fluid collections and prevent organ injuries. Laparoscopic drainage of lymphocele following transplantation results in minimal disability and an acceptable complication rate, although it is higher than with open drainage. Therefore, laparoscopic drainage should be considered as primary treatment for all patients with symptomatic post-transplant lymphocele. Received: 15 March 1996/Accepted: 3 July 1996

Laparoscopic marsupialization of postrenal transplantation lymphoceles

BACKGROUND AND PURPOSE: Clinically significant post-transplantation lymphoceles are not uncommon. Surgical marsupialization with internal peritoneal drainage is the treatment of choice. We describe the successful laparoscopic formation of a peritoneal window for post-transplantation lymphocele drainage as an effective and minimally invasive procedure. PATIENTS AND METHODS: Between August 1995 and September 2001, 135 consecutive renal transplantations were performed, and 9 patients developed clinically significant lymphoceles. Four of the nine patients were treated by laparoscopic drainage via a peritoneal window. Analysis of predisposing risk factors commonly associated with lymphoceles was performed. The surgical outcome was assessed. RESULTS: Laparoscopic drainage was successful in all patients. The average operative time was 40 minutes. The mean hospital stay was 1.5 days for patients undergoing laparoscopic drainage versus 5 days for those having open surgical drainage. Accidental division of the right native ureter occurred in one patient, which was identified intraoperatively. None of the patients had developed recurrence of lymphocele after a mean follow-up of 10.7 months (range 6-22) months. CONCLUSION: In patients with a clinically significant post-transplantation lymphocele of appropriate size and location, laparoscopic drainage is easy, safe, and effective. It decreases hospital stay and hastens convalescence.     

Laparoscopic drainage of postoperative complicated intra-abdominal abscesses

Intra-abdominal abscess, which carries significant rates of death and complications, may complicate the postoperative course. Treatment options include percutaneous needle aspiration, placement of an external drain under ultrasonic guidance, or surgical drainage, depending on the size, site, and nature (simple or complicated) of the abscess. Laparoscopic drainage may be a treatment option. A retrospective review of patients who underwent laparoscopic drainage of postoperative complicated intra-abdominal abscesses at the authors' institution from January 1997 to July 1999 was performed. Seven patients had complicated intra-abdominal abscesses 7 to 17 (mean 11) days after their initial operation. All abscesses were successfully drained by laparoscopy. The mean operative time was 64 minutes. There were no intraoperative or postoperative complications. The postoperative analgesic requirement was minimal. The suction drain was removed on average 5 days after laparoscopy, and the mean hospital stay was 6 days. There was no recurrence of symptoms at a mean follow-up of 23 months. Laparoscopic drainage, in combination with systemic antibiotics, is a safe and effective treatment option in patients with postoperative complicated intra-abdominal abscesses.
