Abstract Ultrasonically guided, percutaneous fine-needle aspiration biopsy allows final histological and/or cytological diagnosis in patients with benign or malignant space-occupying growths even of small size. Therapeutic puncture and drainage of postoperative abdominal or retroperitoneal growths (haematoma, seroma, lymph cyst, abscess) however, requires 1.) dilatation of the percutaneously established puncture channel and 2.) continuous vacuum aspiration over a period of several days or weeks. We report on three therapeutic punctures in two patients with retroperitoneal lymph cysts following abdominal radical hysterectomy with lymphonodectomy and one patient with abscess formation following nephrectomy. The technique employed was as used in percutaneous nephrostomy. Under local anaesthesia and permanent ultrasound guidance the lesion is punctured with a 1.3 mm hollow puncture needle of three parts (Angiomed) and after aspiration of fluid a 0.9 mm wire guide with a curved, soft tap was inserted through the puncture needle in the lesion. The puncture channel is then dilated under x-ray visualisation with a Teflon-coated fasciadilatator (Cook) to Charr. 16 (20). Finally either a polyvinyl catheter with two lateral apertures (Cook) or a double-barrelled Shirley Drain is inserted and fixed to the skin with a stitch. For diversion a closed system is used. Over a period of one to two weeks 50 to 200 millilitres of secretion are drained off per day in decreasing quantity. The patients returned to normal temperature and recovered entirely. The advantage of our method is the avoidance of dangerous and difficult secondary surgery.
