目的 探讨壶腹癌超声诊断分型在外科治疗中的临床意义。方法 将 31例经手术病理证实的壶腹癌根据超声表现分为 3型 :I型 ,胆总管下段无肿块型 ;II型 ,胆总管下段小肿块型 ;III型 ,胆总管下段明显肿块型。各型均与手术方式对照。结果 31例中I型 5例 (16 .1% ) ,II型 11例 (35 .5 % ) ,III型 15例 (4 8.4% )。I型与II型合并手术切除率 (10 0 % )与III型的手术切除率 (6 0 .0 % )比较差异有显著性意义 (P <0 .0 1)。结论 壶腹癌超声诊断分型对术前制定手术方案、进一步提高手术切除率以及估计壶腹癌的预后有重要的临床意义
Objective To investigate the clinical significance of ultrasonic diagnosis of ampullary carcinoma in surgical treatment. Methods Thirty-one cases of ampullary carcinoma proved by operation and pathology were divided into three types based on the ultrasound findings: type I, no mass in the lower segment of common bile duct, type II and small mass in the lower segment of common bile duct, type III and lower mass in the common bile duct. All types are compared with the surgical approach. Results Among the 31 cases, 5 (16.1%) were type I, 11 (35.5%) were type II and 15 (8.45%) were type III. There was a significant difference between type I and type II surgical resection rates (100%) and type III surgical resection rates (60.0%) (P <0.01). Conclusion The diagnosis of ampullary carcinoma by ultrasound diagnosis has important clinical significance in preoperative surgical planning, further improvement of surgical resection rate and prognosis of ampullary carcinoma
