To determine the prevalence of colonic wall thickening (CWT) and its relation with other clinical and radiological findings of portal hypertension.
Retrospective observational study. The follow-up period was at least 1 year. The colon wall was considered to be thickened when it measured > 6 mm.
The study included 63 patients, what were admitted in Liver Unit of University and General Hospital of Alicante with hepatic cirrhosis who had an abdominal CT scan performed between March 1996 and December 1998.
21 (33.3%) patients showed CWT. This finding was particularly associated with the presence of collateral circulation [ OR = 10.3(1.5-100.8)] and portal thrombosis [OR = 12.8(1.4-118.4)] p<0.05. Patients with CWT tended to develop spontaneous bacterial peritonitis (CWT 14.3% vs no CWT 4.8%) [RR = 3(0.5 -16.6)] but this did not reach statistical significance (p= 0.18).
A third of the patients with cirrhosis and portal hypertension present colonic wall thickening. This finding is related to radiological features and clinical consequences of portal hypertension.
确定结肠壁增厚（CWT）的患病率及其与门静脉高压症其他临床和影像学表现的关系。
回顾性观察研究。随访期至少为1年。当结肠壁厚度>6mm时，认为结肠壁增厚。
该研究纳入了63例患者，这些患者于1996年3月至1998年12月期间在阿利坎特大学综合医院肝病科因肝硬化接受了腹部CT扫描。
21例（33.3%）患者出现结肠壁增厚。这一发现与侧支循环的存在[比值比（OR）=10.3（1.5 - 100.8）]和门静脉血栓形成[OR = 12.8（1.4 - 118.4）]显著相关，p<0.05。结肠壁增厚的患者倾向于发生自发性细菌性腹膜炎（结肠壁增厚组为14.3%，无结肠壁增厚组为4.8%）[相对危险度（RR）=3（0.5 - 16.6）]，但未达到统计学显著性（p = 0.18）。
三分之一的肝硬化和门静脉高压患者存在结肠壁增厚。这一发现与门静脉高压的影像学特征和临床后果相关。
