腹内疝CT诊断的探讨

CT Diagnosis of Interabdominal Hernia

目的加强对腹内疝CT表现的认识,提高腹内疝的CT诊断水平。方法回顾性分析16例经手术证实的腹内疝患者的临床及CT资料。结果 16例术前CT检查均表现为小肠梗阻,6例发生绞窄。10例术前考虑为腹内疝。术后证实16例患者均有腹内疝,其中大网膜裂孔疝1例,肠系膜裂孔疝3例,盲肠周围疝1例,肠粘连束带内疝10例,胃切除术吻合口后疝1例。各型腹内疝CT的共有征象和个体征象与手术结果存在相关性。结论仔细察查CT图像上小肠的走行及梗阻部位的形态,可以对本病给予明确诊断或提示。

Objective To strengthen the understanding of interabdominal hernia CT performance and improve the level of CT diagnosis of interabdominal hernia.Methods The clinical and CT data of 16 patients were analyzed retrospectively.Results In all of 16 cases, CT showed intestinal obstruction before operation, strangulation of 6 cases.10 cases were diagnosed as interabdominal hernia before operation. In all of 16 cases, who were diagnosed as interabdominal hernia after operation,including 1 cases of greater omentum hernia, 3 cases of mesenteric hiatal hernia, 10 cases of internalabdominal inalhernia and 1 cases of pericecal hernia induced by accretion after operation.Common and individual CT signs of interabdominal hernia correlated with results of operation and pathology. Conclusion Interabdominal hernia can be diagnosed or indicated by CT image by depicting position of obstruction and shape of small intestine.
