目的探讨胸腔胃-气管(主支气管)瘘的CT诊断价值,寻找一种无创伤、无刺激性的诊断方法。方法回顾性分析7例具有完整临床资料的胸腔胃-气管(主支气管)瘘CT表现。结果CT显示气管下段与胃腔相通3例,气管隆突左后壁与胃腔相通1例,左主支气管与胃腔相通2例,右主支气管与胃腔相通1例,其瘘口直径5~15 mm;1例胸腔胃-气管瘘瘘口小而未能显示。结论CT是胸腔胃-气管瘘无创伤性、无刺激性检查确诊手段,并能为下一步制订气道内支架置入治疗方案提供详尽资料。
Objective To investigate the value of CT in the diagnosis of thoracic stomach-trachea (main bronchial) fistula and to find a noninvasive and non-irritating diagnostic method. Methods A retrospective analysis of 7 cases of thoracic gastric - tracheal (main bronchial) fistula with complete clinical data was performed. Results CT showed that the lower trachea was connected to the gastric cavity in 3 cases. The left posterior wall of the trachea was connected with the gastric cavity in 1 case. The left main bronchus was connected with the gastric cavity in 2 cases. The right main bronchus was connected with the gastric cavity in 1 case. The diameter of the fistula was 5 ~ 15 mm; 1 case of thoracic stomach-tracheal fistula small but failed to show. Conclusion CT is a noninvasive and nonirritating diagnostic method of thoracic gastric-tracheal fistula. It can provide detailed information for the next step in establishing the treatment plan of endobronchial stent implantation.
