Inguinal lymphocele nonresponsive to conservative treatment can be advantageously studied by LS and successfully treated by microsurgical reconstructive procedures, above all if associated to LL. © 2013 Wiley Periodicals, Inc. Microsurgery 34:10–13, 2014. Groin lymphocele (GL) is an important complication after inguinal lymph node dissection, for skin melanoma, vulvar cancer, and venous surgery,
with an incidence varying from 1.3 to 18.9%.[1-3] Conservative resolution is possible through Selleckchem CAL-101 several needle aspirations and compression bandaging, but it usually takes several months to show the risk of infections and other late complications. Recently, the use of intraoperative Isosulfan Blue, modified technique of radical inguinal lymphadenectomyand laparoscopic lymphnode resection, have reduced the incidence of postoperative lymphatic morbidities such as wound dehiscence, infections, lymphorrhoea, and lymphedema. However, the incidence of lymphocele remains significant. Nonoperative treatment of lymphocele arising from lymphatics injured during groin dissection
is not rarely unsuccessful. Different surgical ROCK inhibitor methods have been proposed, but all involve the closure of lymphatics merging at the lymphocele, increasing the risk of postoperative lower limb lymphedema or of worsening lymphedema if already clinically evident. In this report, we assessed the efficacy of a diagnostic and therapeutic protocol to manage inguinal lymphocele using lymphoscintigraphy (LS) and microsurgical procedures. Sixteen patients with unilateral GL were included in this report. Lymphocele was present for a mean period of 5.7 months (3–8 months) before surgical treatment. None of the patients had responded to
conservative treatment, including needle aspiration, sclerosing therapy, and compression. Infection occurred in three patients, with lymphangitis and fever. The mean age of the patients was 53.4 years (42–63 years). The size of lymphoceles varied from 7 to 12 cm in diameter. Seven of them presented also clinically evident leg lymphedema (LL) at the same side of the lymphocele. All of them had been previously treated nonoperatively by needle aspiration, Proton pump inhibitor sclerosing agents, and compression bandaging without healing of the pathology and relapse of lymphocele. Diagnostic investigations included venous ultrasound and superficial and deep LS of lower limbs. The patients’ information is shown in Table 1. To quantify visual findings in LS, the Kleinhans transport index (T.I.) was used. In this index, five parameters describe the lymph flow: lymphatic transport kinetics (K), distribution pattern (D), time lapse to appearance of lymph nodes (T in minutes, multiplied by 0.04), assessment of lymph nodes (N), and assessment of lymph vessels (V).
