Treatment of recurrent inguinal lymphocele by lymphatic leakage mapping and subsequent ligation of lymphatic vessel endings: a case report

LVAs in a Pedicled SIEA Flap for the Treatment of Recurrent Lymphocele of the Groin Using Superficial Veins of the Flap for Lymphovenous Anastomosis: A Case Report and Literature Review

Persistent lymphocele of the groin is a complication of groin surgery that can severely impact the quality of life. The restoration of the interrupted lymphatic pathway is considered by many authors the ideal treatment to prevent a recurrence. However, multiple aspiration procedures and surgical revisions can compromise the availability of local veins needed for a lymphovenular bypass surgery. In addition, surgical debridement of a long-standing lymphocele can generate extensive dead space and contour deformity. A flap delivering additional venules for trans-flap lymphovenular anastomoses (LVAs) can overcome both problems by providing soft tissue and competent veins harvested outside the zone of injury. A successful case of severe groin lymphocele treated with trans-flap LVAs from an abdominal-based flap is presented. The patient was referred to us for a recurrent lymphocele developed in the right groin after lipoma excision that persisted despite multiple surgical attempts. After the identification of patent and draining inguinal lymphatic vessels, a pinch test was used to design a mini-abdominoplasty superficial inferior epigastric artery flap. The superficial veins of the cranial incision were identified and anastomosed to the lymphatic vessels after the pedicled flap harvested and insetted in the groin. The early restoration of lymphatic drainage and the optimal aesthetic outcome supports the combined approach offered by trans-flap LVAs as a valuable therapeutic option for severe and persistent lymphocele.

Wound Complication Rates after Inguinal Lymph Node Dissection: Contemporary Analysis of the NSQIP Database

BACKGROUND

Inguinal lymph node dissection (ILND) is used for diagnosis and treatment in penile cancer (PC), vulvar cancer (VC), and melanomas draining to the inguinal lymph nodes. However, ILND is often characterized by its morbidity and high wound complication rate. Consequently, we aimed to characterize wound complication rates after ILND.

STUDY DESIGN

The NSQIP database was queried for ILND performed from 2005 to 2018 for melanoma, PC, or VC. Thirty-day wound complications included wound disruption and superficial, deep, and organ-space surgical site infection. Multivariable logistic regression was performed with covariates, including cancer type, age, American Society of Anesthesiologists score ≥3, BMI ≥30, smoking history, diabetes, operative time, and concomitant pelvic lymph node dissection.

RESULTS

A total of 1,099 patients had an ILND with 92, 115, and 892 ILNDs performed for PC, VC, and melanoma, respectively. Wound complications occurred in 161 (14.6%) patients, including 12 (13.0%), 17(14.8%), and 132 (14.8%) patients with PC, VC, and melanoma, respectively. Median length of stay was 1 day (interquartile range 0 to 3 days), and median operative time was 152 minutes (interquartile 83 to 192 minutes). Readmission rate was 12.7%. Wound complications were associated with longer operative time per 10 minutes (odds ratio 1.038, 95% CI 1.019 to 1.056, p < 0.001), BMI ≥30 (odds ratio 1.976, 95% CI 1.386 to 2.818, p < 0.001), and concomitant pelvic lymph node dissection (odds ratio 1.561, 95% CI 1.056 to 2.306, p = 0.025).

CONCLUSIONS

Predictors of wound complications after ILND include BMI ≥30, longer operative time, and concomitant pelvic lymph node dissection. There have been efforts to decrease ILND complication rates, including minimally invasive techniques and modified templates, which are not captured by NSQIP, and such approaches may be considered especially for those with increased complication risks.

Lymphovenous Anastomoses and Microscopic Lymphatic Ligations for the Treatment of Persistent Lymphocele

Numerous approaches have been employed to treat chronic lymphocele and cutaneous lymphatic fistulas (LFs) with little success. Given a high incidence and substantial consequences for patients, there is an ongoing demand for effective therapeutic and preventive strategies. The aim of this study was to evaluate the results after microscopic lymphatic ligation (MLL) and lymphovenous anastomosis (LVA) as a therapeutic and preventive approach in this context.

Methods

Demographic data, surgical characteristics, complications, and the overall outcome of all patients undergoing surgery for postoperative LF from 2014 to 2019 were collected retrospectively. Patients were categorized in accordance with predefined inclusion/exclusion criteria and with their treatment. Statistical analysis was conducted using descriptive, summary statistics to identify a central tendency.

Results

Thirty-four patients underwent indocyanine-green-lymphangiography guided revision surgery for LF. Two patients were lost to follow-up at 6 months. LF was successfully treated in all patients (n = 32) with a multimodal approach. Only MLL was performed in 22 patients and MLL/LVA in 10 patients. LF resolved in 78% of all patients with MLL only or MLL/LVA. In the remaining 22%, LF resolved after additional sclerotherapy within 3 months.

Conclusions

Treatment of LF should follow a standardized staged surgical approach to optimize outcome. LF was treated successfully in all our patients. We therefore propose a multimodal interdisciplinary approach to this common clinical problem that includes adjunctive sclerotherapy.

Ligation of lymph vessels for the treatment of recurrent inguinal lymphoceles following lymphadenectomy

Background

Recurrent lymphocele following groin dissection is generally a self-limiting condition, but in a few cases, the lymphocele persists and for this, there are not many options. Few reports have proposed the efficacy of lymph vessel ligation with patent blue as a vessel locator. We have used this technique since 2007 in our very severe cases and herein present our results.

Methods

The study was a retrospective case series in a university hospital setting. All patients who had this procedure performed were included from the first procedure performed in 2007 until August 2015, and their data was retrieved from electronic patient records.

Results

In total, eight patients had this procedure performed for a total of ten inguinal regions. In all regions, leaking lymph vessels were easily found by the blue color and a median of 3 (range 1–5 vessels) vessels per region were ligated using titanium clips. For two patients, there was still a need for puncture which lasted 13–37 days postoperatively. For the remaining patients, there was an immediate stop in lymphocele formation but one patient developed a lymphatic malformation which after removal resulted in the recurrence of lymphocele and had the procedure performed again with immediate effect.

Conclusions

Ligation of lymph vessels for the treatment of recurrent inguinal lymphoceles appears to be an appropriate treatment modality that is both quick and easy to perform with minimum risk, and in most cases, it results in immediate complete stop in the lymphocele formation.

Treatment of a recurrent inguinal lymphocele in a penis cancer patient by lymphography and selective ligation of lymphatic vessels

We report a case of recurrent inguinal lymphocele formation after inguinal lymphadenectomy treated by lymphographic mapping and selective ligation of the lymphatic vessels. Lymphographic mapping was performed by puncturing a lymphatic vessel at the dorsum of the foot. After isolating the vessels that drained into the lymphocele, they were clipped and divided through a small skin incision. The described technique showed an instant and complete suspension of the lymph secretion with subsequent complete healing. Lymphatic mapping and selective ligation of afferent lymphatic vessels proved to be an effective treatment of a recurrent inguinal lymphocele.

Sclerotherapy with bleomycin for recurrent massive inguinal lymphoceles following partial vulvectomy and bilateral lymphadenectomy—Case report and literature review

BACKGROUND

Formation of lymphoceles following radical vulvectomy presents a formidable problem that is associated with high degree of morbidity. A variety of approaches have been described in the literature to treat this condition.

CASE

An 82-year-old woman developed massive inguinal lymphoceles following partial vulvectomy and inguinal lymphadenectomy for cancer vulva. The lymphoceles involved wide surface areas extending to both flanks, and accumulation of lymph was very rapid at a rate of 1 l daily. The condition failed to respond to continuous drainage and compression for 6 weeks, but responded quickly to sclerotherapy using bleomycin without any significant side effects.

CONCLUSION

Intracavitary bleomycin could be used safely and effectively in huge rapidly accumulating lymphoceles.

The prevention and management of treatment related morbidity in vulval cancer

The traditional and the most common management of primary vulval cancer is radical surgery of the vulva and radical groin lymphadenectomy (unilateral or bilateral). Adjuvant radiotherapy is used in poor prognosis cases. Rare vulval cancers, locally advanced cancers and recurrent vulval cancers often are treated with a combination of surgery, radiation therapy and chemotherapy. The treatments, while often curative, are associated with considerable morbidity, which, until recently, has not been well publicized or quantified. Increasingly, younger patients are presenting with extensive and often multi-focal pre-invasive disease and with vulval cancer. Long-term post-treatment physical, sexual and psychological morbidity is of major concern. There is more onus on clinicians to provide less radical but equally curative treatment, while also reducing morbidity. There is also the need to provide treatment and treatment modification based on supporting evidence. For a rare disease such as vulval cancer it is more difficult to generate data and to conduct trials on treatment modifications. Although surgical modifications have been made, the morbidity of radical surgery for vulval cancer is considerable. The prevention and management of treatment-related morbidity will continue to challenge the gynaecological oncology team.

Intraoperative use of isosulfan blue in the treatment of persistent lymphatic leaks

BACKGROUND

Lymphatic leaks are a major source of morbidity after lower extremity vascular surgery. We determined the ability of isosulfan blue (Lymphazurin) use to identify and help ligate offending lymphatics, and compared postoperative complication rates and length of stay versus nonoperative therapy alone.

METHODS

From January 1993 through March 2002, we identified 15 patients with lymphatic leaks. The first group consisted of 5 patients treated nonoperatively. The second group was 10 patients (11 explorations) treated operatively aided by isosulfan blue, after a trial of nonoperative therapy.

RESULTS

Isosulfan blue identified the leak in 10 of 11 cases. Mean drainage time for the nonoperative group was 47.6 days versus 1.8 days for the operative group (P = 0.036). Within the operative group, the mean drainage time during their initial conservative treatment phase was 15 days versus 1.8 days after surgery (P < 0.01). Complications were significantly less in the operative group (P < 0.05). Postoperative length of stay was a mean of 4.7 days versus 8.1 days for nonoperative patients (P = not significant).

CONCLUSIONS

Intraoperative isosulfan blue use accurately identifies disrupted lymphatic channels and helps ensure definitive ligation. This simple procedure is associated with fewer complications, and a trend toward shorter hospital stay.
