食管癌Ivor-Lewis和Sweet手术的解剖病理学评价

目的比较中段食管癌手术治疗术式的利弊,以提高食管癌的手术疗效。方法选择2010年1月至2012年6月位于食管中段的食管癌住院手术患者110例,依据术式不同,即经右胸Ivor-Lewis手术和左胸Sweet手术,将病例分为Ivor-Lewis组55例和Sweet组55例。对比分析2组术后切除标本的食管长度、肿瘤浸润和切除距离、切缘癌残留的发生率、胸腔和腹腔淋巴结清除的数量及癌浸润淋巴结的阳性率等,并以问卷调查的方式对医师参加Ivor-Lewis组和Sweet组术中处理胸部和腹部的解剖学问题进行评分比较。结果在食管切除长度、淋巴结清除个数方面Ivor-Lewis组明显大于Sweet组(P0.01);Ivor-Lewis组食管癌切缘癌残留阳性发生率为1.82%,显著低于Sweet组的21.82%(P0.01);问卷调查手术医师对2组术中解剖问题评分Ivor-Lewis组明显优于Sweet组。结论食管中上段癌外科手术建议采取Ivor-Lewis术式,贲门部及下段食管癌适宜Sweet手术。

Anatomical and pathological evaluation of Ivor-Lewis and Sweet for esophageal carcinoma operation

Objective In order to improve the surgical treatment for midpiece esophageal carcinoma, different surgical ways were com- pared. Methods From January 2010 to June 2012, 110 patients with midpieee esophageal cancer in our hospital were divided into the Ivor- Lewis group （55 cases） and the Sweet group （55 cases） according to different surgical ways, that is to say Ivor-Lewis surgery via right chest and Sweet surgery through left chest. Length of specimens, rang of tumor invasion, distance of removal, incidence of residual carcinoma in the esophageal edges, number of lymph nodes removed in chest and abdomen, and positive rate of carcinoma infiltrated lymph nodes were compared between the two groups. Questions of surgical anatomy were investigated through questionnaire among surgeons of the two groups, and the scores of both groups were analysed. Results The length of resected specimens and number of lymph nodes removed in Ivor-Lewis group was significantly lager than that of the Sweet group （P 〈 0.01 ）. The positive rate of carcinoma infiltrated lymph nodes in Ivor-Lewis group was 1.82% , which was significantly lower than 21.82% in the Sweet group （ P 〈 0.01 ）. Results of questionnaire showed surgeons have gieven higher scores to Ivor-Lewis group. Conclusion Ivor-Lewis surgery is recommend for upper and midpiece esophageal carcinoma while Sweet surgery is more suitable for cardial and lower esophageal cancer.
