意外胆囊恶性肿瘤的外科治疗

目的探讨意外胆囊恶性肿瘤(UGC)的外科治疗和预后。方法回顾性分析1996年1月—2003年12月浙江大学医学院附属第二医院外科18例UGC患者(UGC组)的临床及病理资料,并与同期有随访资料的43例手术前确诊的胆囊恶性肿瘤患者(DGC组)进行比较。结果UGC组中未侵犯浆膜者占55.6%(10/18),DGC组中肿瘤侵犯浆膜伴局部区域淋巴转移者占90.7%(39/43)。UGC组与DGC组根治性手术切除率分别为72.2%(13/18)和39.5%(17/43);根治性手术后累积5年生存率分别为54.6%和23.5%(χ2L=16.33,P<0.01)。全组61例患者根治性手术与姑息性手术后中位生存期分别为43.3个月和10.5个月(χ2L=31.10,P<0.01)。结论UGC总体预后好于术前确诊的胆囊恶性肿瘤,发现后应尽早积极进行再次根治性手术。早期诊断和再次采取手术根治能改善UGC患者的预后。

Surgical treatments of preoperative unsuspected gallbladder carcinoma

OBJECTIVE: To explore the surgical treatment of preoperative unsuspected gallbladder carcinoma (UGC) and its prognosis. METHODS: Eighteen patients of UGC admitted in our hospital from January 1996 to December 2003 were analyzed retrospectively. The clinicopathological characters and surgical treatment of UGC patients were compared with the preoperative diagnosed gallbladder carcinoma (DGC) patients admitted in the same period. The cumulative survival rate of the patients received radical resection in two groups was analyzed by Kaplan-Meier method. RESULTS: The serous layer was not invaded by tumor in 10 patients of UGC group (55.5%, 10/18), while the serous layer invaded and regional lymph node metastasis were detected in 39 patients of DGC group (90.7%, 39/43). Radical resection rate was 72.2% (13/18) in UGC group and 39.5% (17/43) in DGC group, and 5-year survival rates in those with radical resection were 54.6% and 23.5%, respectively (chi(L)(2) = 16.33, P < 0.01). Compared with the patients underwent palliative operation, the patients with radical resection has a longer median survival time (43.3 months vs 10.5 months, chi(L)(2) = 31.10, P < 0.01). CONCLUSIONS: The prognosis of UGC is better than that of DGC generally. Reoperation for UGC should be performed as soon as possible, and the prognosis can be improved by radical resection.
