【摘要】 目的:探讨双吻合技术(double stapling technique,DST)在中低位直肠癌保肛手术(sphincter-reserving operation,SPO)中的应用价值及并发症的防治。方法:对比分析采用DST者32例(研究组)与采用单吻合技术者(single stapling technique,SST)43例(对照组)两组患者临床病理指标、术后并发症及肿瘤复发情况。结果:全组患者手术顺利,无手术死亡。两组患者在术后3个月和6个月时的排便功能比较差异有统计学意义(P<0.05),但1年后两组大部分患者排便功能基本正常。DST组术后发生吻合口瘘3例(9.38%),吻合口狭窄4例(12.5%),吻合口出血1例(3.13%),局部复发2例(6.25%);SST组术后发生吻合口瘘2例(4.65%),吻合口狭窄3例(6.98%),吻合口出血2例(4.65%),局部复发2例(4.65%)。结论:DST在中低位直肠癌手术治疗中是有效、安全的,能够提高中低位直肠癌保肛手术成功率,改善患者生存质量。更多还原

【Abstract】 Objective:To study the clinical application and postoperative complication of double stapling technique (DST) in anus-preserving operation of low and middle rectal cancer. Method:From April 2002 to April 2006, clinical data of 75 cases with low and middle rectal cancer were analyzed retrospectively. Of those 32 cases used DST underwent sphincter-reserving operation(SPO),regard as study group;and 43 cases used SST received SPO, as control group. Clinical pathologic parameters、 postoperative complication and tumor recurrence were compared between the two groups. Results:Operation of all the 75 patients was successful without operative mortality. In DST group patients, defecation function was different from SST group after postoperative 3 and 6 months (P<0.05), but defecation function of most of two group patients was basically normal after 1 year, and had no difference. In DST group postoperative complication included anastomotic leakage 3 patients(9.38%), anastigmatic stricture 4 patients (12.5%), anastigmatic bleeding 1 patient (3.13%), local recurrence 2 patients (6.25%);in SST group anastigmatic leakage 2 patient (4.65%), anastomotic stricture 3 patients (6.98%), anastomotic bleeding 2 patients (4.65%), local recurrence 2 patient (4.65%). Conclusion:The clinical application of DST was effective and safe in sphincter preserving operation of low and middle rectal cancer , enable to increase sphincter preserving operation achievement ratio, elevate patients quality of life.更多还原
