During the years 1984-1992, 74 patients of mean age 45 (range 6-71) ye
ars with chronic pancreatic pseudocyst were treated by percutaneous cy
stogastrostomy. They comprised 45 men and 29 women. A diagnosis of chr
onic pancreatitis was verified in 55 patients (74 per cent); pain was
the indication for treatment in all cases. The catheter was successful
ly placed at the first attempt in 68 patients (92 per cent). Immediate
complications occurred in four patients (5 per cent); there have been
none since 1986. Abscess formation was seen in eight patients (11 per
cent). One patient died 4 days after the procedure from myocardial in
farction giving a mortality rate of 1 per cent; no death has occurred
since 1986. The mean observation time was 27 (range 0-108) months. Pai
n disappeared or decreased in almost 90 per cent of patients and weigh
t gain was seen in 80 per cent. The method described is less traumatic
than operation, and mortality and complication rates compare favourab
ly with those seen after surgery; the results are at least as good.
