1,226 cases of colorectal cancer were treated
surgically between 1956-1978. 798 (65.09%) were
rectal, 74.3% 0f which were located below the
peritoneal reflection. Dukes C2 cases and cases
with distant metastasis constituted 39.15To and
Dukes' A cases 9.22%. Resectability rate was
75.1% (77.6% for rectal cancer). 32.96% of 619
cases of rectal excision had restorative resection.
84.8% 0f the combined excision for extraperi-
toneal lesions in female patients were posterior
pelvic exenteration. The overall operative mor-
tality rate was 2.93%. Mortality rate of resec-
tion was, 1.73(70 and that of rectal resection 0.8%。
and curative rectal resection 0.63%. Follow up
rate was 94.13% The 5- and 10-year survival
rates for rectal resection were 53.08To and 47.65%,
for curative rectal resection 66.91To and 60.27To,
and for Dukes' A cases 98.05% and 96.39%. The
5- and 10-year survival rates for colonic resec-
tion were 59.79% and 52.18%, for curative colonic
resection 72.79% and 62.06%, and for Dukes' A
cases both 100%. Among factors affecting the-
rapeutic results, local immunologic reaction of
the host is also important, showing that the more
lymphocytic infiltration in and around cancer,
and the more follicular hyperplasia and sinus
histiocytosis in regiona.l lymph nodes the better
the prognosis. Anal preservation in radical re-
section of rectal cancer and improving results
in the treatment of extraperitoneal rectal cancer
are discussed in detail. 相似文献

低位直肠癌局部切除术的合理选用 总被引:5,自引:0,他引:5
1988·1-1994·12手术治疗结直肠癌886例中,癌肿局限肠壁内者324例,按照国际TNM分期,属Tis17例,T2 264例,Tis组中全部为No,T1组中有3例N1,占6.98%,无M1-T2组中N1 74例,占28.03%,M1 10例,占3.79%,不同大体类型癌肿的Tis和T1并无明显区别,增生型T1的N1占27.12%,溃疡型T1的N1占28.95%,浸润型T2的N1占28.13%,三者亦无差异(P>0.05),不同恶性程度Tis与T1间并无区别,低恶性T2的N1占21.43%,一般恶性的N1占27.93%,二者相比P>0.05,高恶性T3的N1占42.86%,与前二者相比,差异显著(P<0.05),324例中有35例低位直肠癌采用局部切除术治疗,占同期低位直肠癌的9.38%,无手术死亡,除1例T1于术后2年出现局部复发,再次行Miles术后又2年死亡外,余均健在,21例术后存活已大农业3年心上,10例存活已满5年,表明肌层浸润不但具有较高淋巴播散率,且有远处转移可能,为保证手术手术疗效,局部切除术应仅限于病变局限在粘膜或粘膜下,≤3cm,低恶性或一般恶性的癌肿。 相似文献

<正>管状吻合器适用于肠道作端端吻合的病例,其优点许多,它缩短了手术时间(一般可缩短40%~60%),在很大程度上避免了由于个人手缝技术因素而造成的并发症,使吻合口瘘发生率有明显下降,尤其适用于直肠中、下段癌肿切除术后的低位直肠吻合.因此,对传统外科手术肠胃吻合是一次重大改进.由于手术时间缩短,减少了手术野的暴露时间和对组织的触摸、刺激,减少了组织的损伤,必然降低了手术污染的机会,降低术后感染率.由于手术时间缩短,也必然减少麻醉时间及麻醉剂量,对机体及肠道功能的恢复均起着良好的作用.使病人能早日康复,早日出院,节省了住院费用. 相似文献

据上海市肿瘤研究所统计,大肠癌的发病率近年来有所增高,1978年达20.14/10万人,占恶性肿瘤的第四位,死亡率为12.39/10万人,占恶性肿瘤致死的第五位。大肠癌的发病率在各地并不一致,据血吸虫病流行区浙江省嘉兴专区1978年资料,本病发病率为23.98/10万人,死亡率为11.38/10万人,均为该区恶性肿瘤发病率和死亡率的首位。本文总结我院自1956年至1978年底,施行手术1226例大肠癌的外科治疗经验和远期疗效。 相似文献

直肠腔内超声诊断直肠肿块及判断其浸润深度的探讨 总被引:8,自引:0,他引:8
目的:为进一步提高腔内超声对直肠肿瘤的诊断水平。方法:本研究将133例经直肠腔内超声检查的直肠腔内、外肿块与手术及病理作对照分析。结果:恶性肿瘤100例(占75.18%),良性肿瘤14例(占10.52%),其他良性病变19例(占14.28%)。共检查出131例,符合率98.49%(131/133),2例为假阴性,无假阳性。恶性肿瘤中直肠癌96例,腔内超声提示浸润深度与病理结果相符78例,准确率为81.25%(78/96),浸润深度误判18例,占18.75%(其中判断过深13例,过浅5例)。结论:腔内超声的应用为直肠肿块的检查提供了一个直接、简便、安全的新方法 相似文献
