Abstract
Retroperitoneal lymph node dissection (RPLND) is utilized in low‐stage testis cancer as a primary diagnostic and therapeutic procedure. In the post‐chemotherapy setting, it serves as an adjuvant procedure to resect residual tumor. Primary RPLND entails minimal resection of lymphatic tissue in the retroperitoneum; the complications are minor and insignificant. Wound infection is the main complication, affecting less than 5% of patients. Atelectasis and small bowel obstruction may occur in less than 2% of patients. In post‐chemotherapy RPLND, the template and the surgical challenge are much larger. Extensive tumor size, difficult location, adherence to major vessels, and vital structures, together with inferior pre‐operative status, are probably the main reasons for complications. The overall complication rate is 20% to 35% and mortality is 0.8% to 1%. Pulmonary insufficiency secondary to bleomycin‐induced interstitial fibrosis is the cause of the most severe side effects and mortality in these operations. Chylous ascites may occur, especially where resection of the inferior vena cava is necessary. Other complications occur to a lesser extent. A summary of all complications is presented and measures to avoid or manage them are depicted. Semin. Surg. Oncol. 17:263–267, 1999.
