The gastrocolic trunk (GT), consists of the veins from stomach, duodenum, pancreas and colon, passes transversely in front of the head of the pancreas and drains to the superior mesenteric vein at the lebel of the uncus. Pancreatic and/or portal venous pathology may cause dilatation or occlusion of the GT. The purpose of this study is to clarify the usefulness of X-ray computed tomography (CT) for evaluation of the GT and its tributaries in the diagnosis of pancreatic disease. The CT examinations of 176 patients (97 with pancreatic disease, 79 without pancreatic or liver disease for comparison) were reviewed retrospectively. In the comparison group, a normal GT was identified in 81% of CT scans with 5mm thick sections. Abnormal findings of the GT and its tributaries were seen in 30 cases with the involvement(occlusion or stenosis) of the portal venous system in the group of pancreatic diseases. The GTs were occluded in 17 cases with involvement of GT or SMV and dilated in 5 cases with involvement of the portal vein, SMV, or splenic vein by pancreatic diseases. In 3 cases, GTs were minimally dilated without abnormality of the portal venous system. The right gastroepiploic veins were dilated in 15 cases with splenic vein obstruction (5 patients), GT obstruction (6), SMV stenosis (3), stenosis of main portal vein (1). Assessment of the GT and its tributaries on CT would be useful for evaluation of the extension of the pancreatic disease.
胃结肠干（GT）由来自胃、十二指肠、胰腺和结肠的静脉组成，在胰头前方横向走行，在钩突水平汇入肠系膜上静脉。胰腺和/或门静脉病变可能导致胃结肠干扩张或闭塞。本研究的目的是阐明X线计算机断层扫描（CT）在评估胃结肠干及其分支以诊断胰腺疾病方面的实用性。回顾性分析了176例患者的CT检查结果（97例患有胰腺疾病，79例无胰腺或肝脏疾病作为对照）。在对照组中，81%的5mm厚层CT扫描显示胃结肠干正常。在胰腺疾病组中，30例门静脉系统受累（闭塞或狭窄）患者的胃结肠干及其分支出现异常表现。17例胃结肠干或肠系膜上静脉受累患者的胃结肠干闭塞，5例胰腺疾病累及门静脉、肠系膜上静脉或脾静脉患者的胃结肠干扩张。3例患者胃结肠干轻度扩张，门静脉系统无异常。15例脾静脉梗阻（5例患者）、胃结肠干梗阻（6例）、肠系膜上静脉狭窄（3例）、门静脉主干狭窄（1例）患者的胃网膜右静脉扩张。CT上评估胃结肠干及其分支对评估胰腺疾病的范围很有用。
