摘要目的评价CT对于行Roux-en-Y胃旁路术后腹内疝(IH)诊断的准确性,进而建立诊断路径以提高诊断准确性。材料与方法对行腹腔镜下Roux-en-Y胃旁路术病人进行回顾性分析,并经伦理委员会同意,经证实有IH的76例,无IH的78例。由2位放射科医师独立分析之前诊断IH的CT征象:肠系膜扭转、小肠梗阻(SBO)、蘑菇征、聚集的肠袢、飓风眼征、肠系膜上动脉后位小肠、右位吻合口。同时评估2个新征象:肠系膜上静脉(SMV)鸟嘴征、肠系膜血管十字交
Abstract Objective To evaluate the diagnostic accuracy of CT for intra-abdominal hernia (IH) after Roux-en-Y gastric bypass and to establish a diagnostic pathway to improve diagnostic accuracy. Materials and Methods Retrospective analysis was performed on patients undergoing laparoscopic Roux-en-Y gastric bypass surgery. With the approval of the Ethics Committee, 76 confirmed cases of IH and 78 cases of no IH were identified. CT signs of previously diagnosed IH were independently analyzed by 2 radiologists: mesenteric torsion, small bowel obstruction (SBO), mushroom sign, aggregated intestinal loop, hurricane eye sign, posterior small intestine of superior mesenteric artery, right anastomosis. Two new signs were also evaluated: superior mesenteric vein (SMV) beak syndrome, mesenteric vascular cross
