经肛管括约肌切除直肠绒毛状腺瘤   总被引:5,自引:1,他引:5  
作者报告经肛管括约肌径路切除直肠绒毛状腺瘤24例。其中良性绒毛状腺瘤13例,绒毛太腺瘤伴部分细胞高度不典型增生2例。绒毛状腺瘤癌变9例。除1例发生伤口感染外,余皆获得满意疗效。无手术死亡,未发生直肠瘘和肛门失禁。作者就外科治疗直肠绒毛状腺瘤的各种手术方式进行了比较和讨论,认为经肛管括约肌径路切除直肠绒毛状腺瘤是比较理想的一种手术方式。  相似文献

目的 探讨超低位直肠肿瘤经括约肌间切除术( intersphincteric resection,ISR)后内括约肌不同缺失程度对大便失禁的影响.方法 选取71例直肠肿瘤患者分别行低位前切除术、部分ISR、次全ISR、完全ISR,依次作为A组(内括约肌完整组)、B组(内括约肌缺失1/3组),C组(内括约肌缺失2/3组),D组(内括约肌完全缺失组),采用肛门直肠测压和Vaizey评分系统跟踪随访4组患者术后1年内大便失禁程度的动态变化,并用重复测量方差和多元方差分析对数据进行分析.结果 术后4组肛管高压区长度均有不同程度缩短,随着术后时间推移高压区长度略有延长,但至术后12个月4组之间差异仍有统计学意义(F=41.873,P=0.000).4组肛管最大静息压均明显下降,至术后12个月时有不同程度恢复:A组恢复至接近术前水平;B、C组皆升至约术前2/3水平,两组差异无统计学意义(P=0.30);D组升至术前的1/3水平.术后10d时4组患者均出现Vaizey评分上升,此后B、C两组下降趋势相同,术后12个月时两组差异无统计学意义(P =0.158),并接近于A组;D组至术后12个月为13.7±3.2.多元回归分析显示,术后12个月,肛管最大静息压、肛管高压区长度与大便失禁的主观评分Vaizey评分呈负相关(t=-4.802,P=0.000;t=-2.011,P=0.048).结论 超低位直肠肿瘤患者术后12个月内大便失禁严重程度Vaizey评分与肛管最大静息压、肛管高压区长度相关.术后一年时绝大多数超低位直肠肿瘤切除患者可获得比较满意的控便功能.  相似文献

内括约肌切除术治疗超低位直肠肿瘤26例   总被引:1,自引:1,他引:1  
目的 总结用肛门内括约肌切除术治疗超低位直肠肿瘤的临床经验.方法 对26例无外括约肌受侵的低位直肠肿瘤患者行全直肠系膜切除加经肛内括约肌切除术的临床资料进行回顾性分析.对肿瘤下缘距齿状线 2 cm者,行内括约肌部分切除;肿瘤下缘距齿状线 1.0 cm、<2.0 cm者,行内括约肌次全切除;肿瘤距齿状线<1.0 cm或侵及齿状线者,行内括约肌全切除,结肠肛管行端端吻合.结果 26例患者肿瘤下缘距齿状线距离为0~3 cm.病理类型:高分化腺癌6例,中分化腺癌16例.乳头状癌1例,绒毛状腺瘤癌变1例.巨大绒毛状腺瘤2例.病理分期:pTNM Ⅰ期11例,ⅡA期8例,ⅢA期4例,ⅢB期1例;T分级:T1 8例,T2 15例,13 1例.全组无手术死亡;无吻合口瘘;发生吻合口狭窄2例.术后早期肛门经常粪污,每日大便3~10次.术后1年控便时间可达5 min以上,患者排便次数减少,最少为每日1次,或每日2~4次.但内括约肌全切除者仍偶然粪污.术后平均随访时间28个月,术后5个月吻合口肿瘤复发1例,术后10个月肝转移1例,术后26个月心源性猝死1例.结论 对于癌灶局限于直肠壁内的超低位直肠癌,采用肛门内括约肌切除术可以达到根治效果,并保留肛门功能.  相似文献

目的探讨经肛门括约肌手术在中低位直肠肿瘤局部切除术中的作用和疗效。方法对1990年3月至2007年3月采用经肛门括约肌手术的97例中低位直肠肿瘤病例进行回顾性分析。结果全组行直肠部分切除术91例,直肠节段切除术6例。术后并发伤口感染5例(5.2%),直肠皮肤瘘4例(4.2%)。术后病理结果为:直肠绒毛状腺瘤35例,直肠癌50例,直肠类癌等12例。直肠癌中Tis期17例,T1期21例,T2期7例,T3期2例,T4期3例。术后平均随访6.4年(2个月~16年)。术后肿瘤局部复发3例(6.2%)。术后3年和5年生存率分别为93.7%和87.5%。本组无手术死亡,无术后肛门失禁。结论经肛门括约肌直肠肿瘤局部切除术具有手术创伤小、风险低和易于保留肛门等优点,适用于中低位直肠肿瘤的治疗。  相似文献

Objective To study the combination of trans-anal intersphincteric resection and trans- abdominal total mesorectal excision for anus-retained ultra-low rectal tumors. Methods Clinical data of 34 ultra-low rectal tumor patients without external anal sphincter involved, who underwent the combination surgery, were retrospectively analyzed Results The distance from the distal incisal margin of the rectum to the inferior margin of the tumor ranged from 1.8 cm to 3.0 cm on an average of 2. 1 cm. For pathological types, there were 23 cases of adenocarcinoma (9 well differentiated and 14 moderately differentiated), 1 papillary carcinoma, 2 rectal stromal tumor, 5 rectal villous adenoma with canceration and 3 giant villous adenoma. For pathological stages, there were 18 eases at stage pTNM Ⅰ , 5 at Ⅱ A, 1 at Ⅱ B, 4 at ⅢA, 1 at ⅢB and for T grading, there were 15 cases at stage T1, 5 at T2, 8 at T3, 1 at T4. In these 34 patients, there were 3 cases with postoperative anastomotic stenosis, 2 with postoperative anastomotic rupture, 2 with rectovaginal fistula and no operative death. Because of the dysfunction of bowel control, bowel frequency varied from 3 to 12 in the early stage after operation, but with the recovery of anus function, bowel frequency decreased and ranged form 1 to 5 times a day and the time of formed bowel control could be more than 5 min in 6-12 months after operation. However, patients underwent total resection of internal anal sphincter still suffered from incontinence of loose stool after 1 year. After operation, anastomotic recurrence was found in 1 case in 5 months, liver metastasis in 1 case in 10 months and 28 months respectively, cardiac sudden death in 1 case in 26 months. Conclusion The combination of trans-anal ISR and trans-abdominal TME for anus-retained ultra low rectal tumor is not only coincident with radical tumor principle but also retains the function of anus, on the premise of the strict indication.  相似文献

目的应用直肠肛管向量测压技术评估低位直肠癌经内外括约肌间切除术后肛门括约肌功能。方法对16例行经内外括约肌间切除术的低位直肠癌患者行直肠肛管向量测压,并选择同期30例直肠癌低位前切除术患者及30例肛门功能正常的健康人作为对照研究。结果根据临床症状将经内外括约肌间切除术后患者分为污便组和排便功能良好组,其肛管最大压力、向量容积及对称指数均显著低于正常对照组及低位前切除术对照组(P<0.001);污便组的最大收缩压、收缩向量容积及对称指数明显低于排便功能良好组(P<0.001);行经内外括约肌间切除术后25.0%(4/16)的患者出现直肠肛门抑制反射,明显低于行低位前切除术患者的93.3%(28/30),P<0.001。结论经内外括约肌间切除术后患者肛管最大压力及向量容积下降,肛门功能不如行低位前切除术者。直肠肛管向量测压技术是评估低位直肠癌患者行经内外括约肌间切除术后肛门括约肌功能较客观的方法。  相似文献
