目的:探讨绝经后妇女胃肠道间质肿瘤容易误诊为卵巢肿物的原因,以及它们之间的鉴别点。方法:回顾性分析3例术前诊断为卵巢肿物,术后证实为胃肠道间质肿瘤患者的临床资料。结果:3例患者均为绝经后妇女,2例以急腹症表现入院。她们伴或不伴有肿瘤标记物轻度升高,彩色多普勒超声显示:有急腹症表现者的肿物血流丰富。行盆腔CT检查者2例,1例检查结果提示为小肠肿瘤。术前均诊断为卵巢肿物行开腹手术。术中发现结合术后病理诊断为胃肠道间质肿瘤。有急腹症表现的患者,术中出血量多。结论:绝经后妇女出现盆腔肿物应考虑到有胃肠道间质肿瘤的可能。可能有急腹症表现,术中出血凶险。术前盆腔CT检查有助于术前诊断。
Objective: To explore the causes of misdiagnosis of ovarian stromal tumors in postmenopausal women with gastrointestinal stromal tumors, and to distinguish between them. Methods: The clinical data of 3 patients with preoperative diagnosis of ovarian tumors and postoperative gastrointestinal stromal tumors were retrospectively analyzed. Results: All 3 patients were postmenopausal women, and 2 patients were admitted to hospital with acute abdomen. They had mildly elevated tumor markers with or without tumors. Color Doppler ultrasonography showed that tumors with acute abdomen manifestations were rich in blood flow. Two patients underwent pelvic CT examination, and one case showed a small bowel tumor. All preoperative ovarian cancers were diagnosed by open surgery. Intraoperative findings combined with pathological diagnosis of gastrointestinal stromal tumors. Patients with acute abdomen manifestations have more intraoperative blood loss. Conclusions: Pelvic masses in postmenopausal women should consider the possibility of gastrointestinal stromal tumors. There may be acute abdomen symptoms, bleeding during surgery is dangerous. Preoperative pelvic CT examination is helpful for preoperative diagnosis.
