The purpose of this study was to describe the CT appearances of sclerosing peritonitis (SP) in patients on chronic ambulatory peritoneal dialysis (CAPD) and to compare these findings with the CT appearances in a control group of CAPD patients who did not develop SP.
The CT findings in 10 patients with SP were compared with those from a "control group" of 71 patients without SP who were on long-term CAPD and had also undergone at least one CT examination. Particular reference on CT examination was made to the appearance of the peritoneum and small bowel and the presence or absence of loculated fluid collections.
Peritoneal abnormalities (calcification/thickening) were noted in 100%, loculated fluid collections in 90%, and small bowel abnormalities (tethering/dilatation) in 60% of the patients with SP. In the control group of patients, peritoneal abnormalities were noted in only 7%, loculated fluid collections in 15%, and small bowel dilatation in 5.7%.
Peritoneal thickening, peritoneal calcification, loculated fluid collections, and tethering of the small bowel appear to be diagnostic of SP. In a small group of patients with follow-up CT scans, new, or progression of, CT findings correlated with the clinical severity of SP.
本研究旨在描述持续性非卧床腹膜透析（CAPD）患者硬化性腹膜炎（SP）的CT表现，并将这些结果与未发生SP的CAPD对照组患者的CT表现进行比较。
将10例SP患者的CT表现与71例未发生SP且长期进行CAPD并至少接受过一次CT检查的“对照组”患者的CT表现进行比较。CT检查特别关注腹膜和小肠的表现以及有无局限性液体积聚。
SP患者中100%出现腹膜异常（钙化/增厚），90%出现局限性液体积聚，60%出现小肠异常（粘连/扩张）。在对照组患者中，仅7%出现腹膜异常，15%出现局限性液体积聚，5.7%出现小肠扩张。
腹膜增厚、腹膜钙化、局限性液体积聚和小肠粘连似乎是SP的诊断依据。在一小部分接受随访CT扫描的患者中，新的CT表现或CT表现的进展与SP的临床严重程度相关。
