Summary
The structure of the peritoneum has been studied by scanning and transmission electron microscopy and by light microscopy in 38 biopsies of 22 patients undergoing CAPD. Before CAPD the mesothelium was characterized by flattened cells with protruding nuclei, numerous microvilli and many pinocytotic vesicles. After prolonged CAPD there is a reduction and subsequent disappearance of microvilli and a vacuolar separation of cells from the basement membrane, accompanied by widening of intercellular junctions. Neither ultrafiltration rate nor small solute clearance change with these structural alterations. During peritonitis there is extensive cellular necrosis with denuding of the basement membrane. After recovery the mesothelium is replaced by thick fibrous connective tissue.
