目的 观察左侧结肠癌伴急性肠梗阻一期手术的疗效，探讨理想的手术治疗方法。方法 回顾性分析四川大学华西医院2007年1月至2009年11月期间收治的46例左侧结肠癌伴急性肠梗阻患者一期手术切除吻合的临床资料。结果 46例均未实施术中结肠灌洗，而行彻底的无污染肠减压法。其中行根治性切除一期吻合35例，姑息性切除一期吻合11例。术后发生吻合口漏3例，切口感染6例，肺部感染2例，盆腔积液1例，均经非手术方法治愈。全组手术无死亡病例。结论 左侧结肠癌伴急性肠梗阻一期切除吻合，用彻底的无污染肠减压法替代结肠灌洗是安全、可行的。
目的 探讨预防左半结肠癌伴梗阻Ⅰ期切除吻合术后吻合口漏发生的新方法。方法 将215例左半结肠癌伴梗阻接受术中结肠灌洗和Ⅰ期切除吻合等处理的患者分为两组。双管引流组术中经肛门放置肠腔内双管引流；扩肛组术中不放置肠腔内引流管，术后定时扩肛。对两组患者术后腹腔脓肿和吻合口漏发生率进行对比分析。结果 腹腔脓肿和吻合口漏发生率双管引流组分别为3.1%(4/130)和3.8%(5/130)，扩肛组分别为10.6%(9/85)和12.9%(11/85)，两组腹腔脓肿和吻合口漏发生率之差异均有显著性意义(P＜0.05)。结论 肠腔内双管引流法具有预防性结肠“内造瘘”、减压减张、冲洗洁净和持续性扩肛作用，能有效地预防和减少左半结肠癌伴梗阻I期切除吻合术后吻合口漏的发生。
目的:分析D3根治术在右半结肠癌中的意义。方法:回顾分析我院19874～20037年间的右半结肠癌175例分别采用D3和D2两种术式临床疗效。结果:采用D3术式较D2术式其预后有显著差别(Plt;001)。结论:D3根治术在右半结肠癌手术中有重要意义,应作为标准的根治方式。
目的 探讨腹腔镜结肠癌根治术的临床效果。方法 应用腹腔镜外科技术对25例结肠癌患者实施腹腔镜结肠癌根治术。结果 本组25例手术时间110～310 min，平均195 min； 术中出血量约100～350 ml，平均约180 ml； 术后胃肠功能恢复时间1～4 d，平均 1.7 d。所有标本残端无肿瘤细胞残留、浸润。所有病例术后未出现出血、吻合口漏和狭窄并发症，仅有2例出现伤口感染。术后住院6～10 d，平均7.5 d； 术后19例随访2～38个月，平均13个月，其中2例于手术后第12个月和14个月因肿瘤广泛转移、衰竭而死亡； 余17例随访期间均未发现有转移复发及切口种植。结论 腹腔镜结肠癌根治术具有微创、安全、术后恢复快、肿瘤根治彻底等优点，值得临床推广应用。
Objective To study the feasibility and curative effect of laparoscopic vs. open radical rectectomy and colectomy for colorectal cancer. Methods Sixty-two cases who underwent laparoscopic operation (17， 2， 10， 23， 9 and 1 case underwent radical right colectomy， radical transverse colectomy， radical left colectomy， Dixon， Miles and Hartmann operation respectively) and 78 cases who underwent open operation (17， 4， 11， 27， 18 and 1 case underwent radical right colectomy， radical transverse colectomy， radical left colectomy， Dixon， Miles and Hartmann operation respectively) in our department from Aug. 2001 to Jun. 2008 were included. The clinical data of patients in two groups were compared. Results There were no severe complications and death occurred in both groups and 4 cases in laparoscopic group were converted to open operation during the procedure. The mean operation time of laparoscopic group and open group were (230.6±23.5) min and (145.5±17.6) min respectively, there was a statistical difference between them (P＜0.01). The intra-operative blood loss of laparoscopic group was obviously less than that in open group 〔(135.5±22.5) ml vs. (300.6±34.5) ml， P＜0.01〕. There was no statistical difference of the number of cleared lymph nodes between two groups 〔(11.8±1.5) pieces vs. (13.3±1.7) pieces， Pgt;0.05〕. The length of distal incision margin of rectal anterior resection in laparoscopic group was obviously longer than that in open group 〔(3.1±0.4) cm vs. (2.6±0.3) cm， P＜0.01〕. The gastrointestinal and urinary function of laparoscopic group recovered more quickly than those in open group 〔(2.3±0.7) d vs. (3.6±0.9) d for intake of liquid diet， P＜0.05； (3.5±1.1) d vs. (4.7±1.2) d for intake of solid diet， P＜0.05； (2.3±0.4) d vs. (4.4±1.2) d for duration of urethral catheterization， P＜0.01， respectively〕. The length of hospital stay in laparoscopic group was shorter than that in open group 〔(8.5±0.7) d vs. (12.8±0.9) d， P＜0.01〕. But the cost of hospitalization in laparoscopic group was higher than that in open group 〔(3.14±0.25)×104 yuan vs. (2.02±0.75)×104 yuan， P＜0.05〕. There was no statistical difference of the three-year survival rate between two groups (89.5% vs. 89.1%， Pgt;0.05). Conclusion Laparoscopic radical rectectomy and colectomy for colorectal cancer is feasible and safe with minimal invasiveness.
