ULTRASOUND CHANGES IN SCLEROSING PERITONITIS FOLLOWING CONTINUOUS AMBULATORY PERITONEAL-DIALYSIS

Sclerosis of the peritoneum, with encapsulation of the small bowel is one of the most serious complications of continuous ambulatory peritoneal dialysis (CAPD), and carries a high mortality. The abnormalities seen on ultrasound are described for 14 patients and comprise increased small bowel peristalsis, tethering of the bowel to the posterior abdominal wall, intraperitoneal echogenic strands and, in the late stages of the disease, membrane formation. Optimal visualization of these features in the early stages of the disease was obtained by examining the patients with dialysis fluid present in the abdomen. Sclerosing peritonitis should be suspected in patients being treated by CAPD who develop abdominal pain and progressive loss of ultrafiltration and subsequent investigation should include the use of ultrasound.
