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. 2006 S.
