Peritoneal x-ray and computerized tomography in evaluating abdominal complications in CAPD

CAPD is a widely accepted therapy, however, some patients develop complications that can impede continued therapy. Peritonitis is the most critical problem. A series of complications require accurate examination to avoid discontinuing necessary therapy, i.e.: leakage, inguinal and ventral hernia, trauma, catheter malfunction and scrotal-penile edema. For the past few years we have used peritoneal x-ray to evaluate these complications. Recently we have included computerized tomography with intraperitoneal contrast. We have studied 20 patients since 1985. The empty peritoneal cavity is filled with 100 cc of iopamidol, a non-ionic, low osmolality contrast, containing 300 mg of iodine/ml. No complications were ever encountered during or after these studies. The method has proven most useful in therapeutic decisions permitting, very often, continuing peritoneal dialysis. The results are extremely reliable due to its simplicity and the complete absence of complications.
