根Ⅰ式和根Ⅱ式胃切除术治疗进展期胃癌的比较

为评价根Ⅱ（Ｒ２）胃切除对胃癌病人的利弊，本文分析比较作根治性切除的进展期胃癌共１３１例，病人按淋巴结清扫的范围分成两组。６４例行Ｒ２胃切除，６７例行根Ⅰ（ＲＩ）胃切除。除Ｒ２组（３３／６４）全胃切除率比Ｒ１组（２２／６７）高（Ｐ＜０．０５）外，两组病人的临床和病理情况基本相似。手术时间Ｒ２组明显比Ｒ１组长（Ｐ＜０．０１），输血量Ｒ２比Ｒ１组大（Ｐ＜０．０１）。手术后住院天数两组无显著差别。Ｒ２组６４例中，５例（７．８％）发生外科并发症，Ｒ１组６７例中，发生这类并发症者仅１例（１．５％），两者差别有显著意义（Ｐ＜０．０５）。Ｒ２和Ｒ１组的死亡率为０％和１．５％，无显著差别。３年生存率Ｒ２组为５４．８％Ｒ１组为３７．８％，其差别有显著意义（Ｐ＜０．０５）。以上结果提示，Ｒ２胃切除是可行的，对能根治病例有提高生存率的作用。

Risk factors for operative morbidity and mortality in gastric cancer patients undergoing total gastrectomy

AIM： To study the risk factors for morbidity and mortality following total gastrectomy. METHODS： We retrospectively reviewed the records of 125 consecutive patients who underwent total gastrectomy for gastric cancer at the Second Affiliated Hospital of Zhejiang University School of Medicine between January 2003 and March 2008. RESULTS： The overall morbidity rate was 20.8% （27 patients） and the mortality rate was 3.2% （4 patients）. Morbidity rates were higher in patients aged over 60 [odds ratio （OR） 4.23 （95% confidence interval （CI） 1.09 to 12.05）], with preoperative comorbidity [with vs without, OR 1.25 （95% CI 1.13 to 8.12）], when the combined resection was performed [combined resection vs total gastrectomy only, OR 2.67 （95% CI 1.58 to 5.06）]. CONCLUSION： Age, preoperative comorbidity and combined resection were with the rate of morbidity gastric cancer. independently associated after total gastrectomy for
