Colonic dilatation due to dialysis-related amyloidosis.
A 66-year-old woman with chronic renal failure who had undergone hemodialysis for 15 years developed severe dilatation of the ascending and transverse colon. She had received right carpal tunnel release 5 years before this episode. The follow-up study of upper gastrointestinal series disclosed marked dilatation of the ascending and transverse colon with the retention of gastrografin persisted for 5 days, whereas colonic fiberscope showed no obstructive lesion. Pathologic study of biopsy specimens obtained from the colon demonstrated amyloid deposition. Avidin-biotin peroxidase complex method showed that these deposits strongly reacted with the antibody to human beta 2-microglobulin, but did not react with AA, lambda, and kappa antibodies. This case suggests that dialysis-related amyloidosis can cause intestinal pseudo-obstruction.
