虽然结直肠疾病的手术治疗进展较慢,但借助于近年来微创外科技术、围手术期综合治疗策略和临床研究的进步,中国结直肠外科亦得以快速发展。经肛全直肠系膜切除、盆腔侧方淋巴结清扫、直肠癌新辅助治疗临床完全缓解的“等待与观察”策略、机器人结直肠外科手术等仍然是近年来结直肠外科的热点议题。笔者结合全国性结直肠癌手术病例登记数据库建设以及临床研究等展开论述,以期为同道们梳理结直肠外科的发展脉络,共谋中国结直肠外科的发展。 相似文献

我国腹腔镜结直肠外科的发展 总被引:6,自引:1,他引:5
1990年Jacobs在美国成功完成第一例腹腔镜右半结肠切除术,随后短短数年内所有类型的结直肠手术均在腹腔镜下得以成功施行。1993年郑民华等完成了国内第一例腹腔镜乙状结肠癌根治术,随后国内腹腔镜结直肠手术逐步得到开展,近年更是发展迅猛,国内各家医院纷纷成立了微创胃肠外科中心, 相似文献

腹腔镜结直肠外科的现状与展望 总被引:5,自引:1,他引:4
1 现状自 1 990年美国的 Jacobs进行了世界上首例腹腔镜右半结肠切除术后 ,同年 Folwer进行了腹腔镜乙状结肠切除术。从此腹腔镜技术逐渐运用于传统的结直肠手术 ,但发展速度远不如其他腹腔镜手术 ,主要原因首先是它的手术难度较高 ,需行肠段的切除及重建 ,其次是人们对于肿瘤的根治性有疑虑。经过十余年的不断发展 ,腹腔镜结直肠手术已日臻成熟与完善 ,其良好的近期及远期疗效亦已逐渐得到证实 [1]。我院从 1 993年开始至 1 999年仅完成 5 0例 ,手术时间平均为 1 80 min,以后几年已完成近 80例 ,平均时间降至 1 2 0 min,接近开腹手术所需… 相似文献

结直肠外科的专科化发展及问题思考 总被引:1,自引:0,他引:1
随着中国经济的发展,需要有与之相适应的医疗体系及专业医师培训、准入制度。结直肠外科在欧美是一专科性极强的专业,在我国与结直肠外科相应的是肛肠外科,其主要分布于中医院,而一些大中型医院常常对结直肠肛门疾病不够重视。随着结直肠肿瘤、炎性肠病、便秘等结直肠外科疾病发病率的明显增加以及人们对生存质量的更高要求, 相似文献

结直肠外科疾病由于其生物行为学复杂性,病人高龄倾向、常伴发营养不良、肠梗阻和心理障碍,以及手术后肠道功能障碍、抗肿瘤治疗后的相关并发症、肿瘤转移至其他脏器及手术后的康复等复杂问题往往难以在一个亚专科得到全程解决.因此,对于结直肠外科病人的围手术期管理提出更高要求,但这些复杂多学科问题如何能系统性地得以解决是当前临床的难... 相似文献

基于临床数据挖掘技术的腹腔镜结直肠癌手术评估体系的构建及应用 总被引:1,自引:1,他引:0
目的 整合优势科研资源,搭建良好的科研平台,开展单(多)中心临床试验,以中国人的临床数据科学地评价腹腔镜结直肠癌手术目前仍存在争议的问题.方法 以南方医院2008年10月自主开发的一款专门以腹腔镜结直肠癌手术为数据架构,同时适合于回顾性和前瞻性临床研究,既能科学管理和深度分析临床数据,又能满足多单位合作需要的数据挖掘系统软件为数据平台,构建腹腔镜结直肠癌手术评估体系,开展单(多)中心腹腔镜结直肠癌手术研究.结果 历时1年多的开发和完善,南方医院已经使用该软件系统按照标准回顾性录入1200余例临床资料,构建了单中心腹腔镜结直肠癌手术评估体系.同时该软件系统作为"中国南方腹腔镜结直肠外科研究组(SCLCSG)"的数据平台,已在第1期临床研究项目"腹腔镜与开腹结直肠癌手术的回顾性多中心对比研究"中成功运行,迄今已录入8200余例病例数据.以南方医院数据完成"腹腔镜与同期开腹直肠癌根治术后肿瘤学结果对比研究(单中心)",结果显示,腹腔镜直肠癌根治术的远期复发和生存并不劣于开腹手术,甚至优于开腹手术的肿瘤学结果.结论 该手术评估体系和临床数据挖掘软件设计达到预定目标,在腹腔镜结直肠癌手术领域具有广泛的应用前景和网络化升级扩展的潜能,值得推广. 相似文献

The are currently a number of unsolved clinical questions in colorectal surgery with new surgical principles being introduced without proper scientific high-level evidence. These include complete mesocolic excision with central ligation for colonic cancer, extralevator abdominoperineal excision for low rectal cancer, robotic surgery for various colorectal procedures, laparoscopic lavage without resection for Hinchey Stage III perforated sigmoid diverticulitis, and the use of the single port technique for laparoscopic surgery. Before general implementation the new modalities should ideally be evalueted in randomized studies and meta-analyses. Many randomized studies, however, cannot give the final answer to the research question because they are underpowered and it is therefore important to perform well-designed studies that are large enough to provide the final answer. A way forward could therefore be to form multicenter and even multinational research groups in order to ensure accrual of sufficient sample sizes. 相似文献

2015年,美国医生Francis S.Collins在著名的新英格兰医学杂志上撰文介绍了精准医学的概念。精准医学是近年来出现的新的医学概念。它是以分子基因为基础实现对疾病的诊断和治疗。我们已经进入了一个精准医学的时代。我们也经历了经验医学,循证医学,现在又进入了精准医学的时代。今天,在结直肠癌领域,我们已经看到:精准医学已经在结直肠癌的姑息治疗中发挥着重要作用,如:常用的爱必妥,安维汀和帕尼单抗等。因此,结直肠外科医生应该认真地学习精准医学的概念,了解精准医学在结直肠领域的独特作用。同时,我们也要应用精准医学的概念去认识和解决结直肠癌领域亟待解决的科学问题。而且,我们也要看到精准医学的局限性,客观公正地评价精准医学。 相似文献

Aim The annual scientific meetings of the Association of Coloproctology of Great Britain and Ireland (ACPGBI), the American Society of Colon and Rectal Surgeons (ASCRS), the European Society of Coloproctology (ESCP) and the Royal Australasian College of Surgeons (RACS) are the major fora for presentation of colorectal surgical research. Thus, their content could be a proxy of the content and quality of colorectal surgical research worldwide. We aimed to critically appraise the quantity, quality and topics of colorectal surgical research over the previous 5 years for the above meetings. Method All published abstracts from the ACPGBI, ASCRS, ESCP and the colorectal‐specific component of the RACS from 2006 to 2010 were appraised. Abstracts were coded by predefined categories pertaining to study type and topic. Results Level 1 evidence (systematic reviews/meta‐analyses) and level 2 evidence (randomized controlled trials) comprised 3% (95% CI 1–9%) and 5% (95% CI 2–11%), respectively, of research presented at the meetings. There was a predominance of level 4 evidence (retrospective studies) across all years (mean 54%, 95% CI 44–68%). Operative management was most commonly studied (mean 43%, 95% CI 36–49%). There was minimal research in perioperative care (mean 6%, 95% CI 2–13%) and basic surgical science (mean 6%, 95% CI 2–11%). Research related to perioperative care was significantly higher at the ACPGBI and RACS meetings than the ASCRS and ESCP meetings (P < 0.01). Conclusion The research at these meetings consists largely of retrospective reviews exploring operative management with minimal high quality scientific content. Active steps need to be taken to increase the quantity of high level evidence especially in topics other than operative management. 相似文献

The dissemination of laparoscopic colorectal surgery (LCS) has been slow despite increasing evidence for the clinical benefits, with a prolonged learning curve being one of the main restrictions for a prompt uptake. Performing advanced laparoscopic procedures requires dedicated surgical skills and new simulation methods designed precisely for LCS have been established: These include virtual reality simulators, box trainers, animal and human tissue and synthetic materials. Studies have even demonstrated an improvement in trainees’ laparoscopic skills in the actual operating room and a staged approach to surgical simulation with a combination of various training methods should be mandatory in every colorectal training program. The learning curve for LCS could be reduced through practice and skills development in a riskfree setting. 相似文献

进入21世纪以来,普通外科学发展迅速,理念不断更新,新技术不断涌现,这在结直肠癌治疗领域表现更加具有代表性和特色。尽管手术作为结直肠癌治疗的核心已经相当成熟,但外科领域开展随机对照研究难度很大,很多新的治疗方法和技术的优效性需要一个漫长的证明过程,而规范和科学的开展结直肠癌外科临床研究可能是解决这一问题的根本方法。总结目前结直肠外科的几个热点问题相关临床研究的新进展,结果可以看出,将最大限度地保留功能、获得更好的生活质量与延长生存时间更好的结合在一起是未来结直肠癌外科治疗的目标,而通过开展相应的临床研究,获得更多的循证医学证据,在此基础上让结直肠癌的外科治疗更加规范,是实现这一目标的必由之路。 相似文献

Background Laparoscopic colorectal cancer surgery has become widely accepted recently. However, the oncological validity of this surgery
has not yet been well analyzed, especially for advanced cancer. The aim of this study is to assess the clinical outcome of
laparoscopic surgery for stage II/III colorectal cancer in our hospital.
Patients and methods Between June 1999 and August 2006, 321 patients underwent laparoscopic colorectal cancer surgery in our hospital; of those
121 cases whose pathological findings revealed stage II/III were included in this study. Among these cases, we assessed a
short-term outcome and a medium-term outcome in terms of survival evaluation.
Results The male:female ratio was 73:48, and mean age of patients was 62.4 years. Thirteen tumors were located in the cecum, 29 in
the ascending colon, five in the transverse colon, one in the descending colon, 43 in the sigmoid colon, and 30 in the rectum.
Average duration of operation was 184 minutes, and mean estimated blood loss was 53.5 ml. Five patients (4.1%) were converted
to open procedures. No intraoperative complication was observed but eight complications (6.6%) occurred postoperatively. Forty-two
cases were classified as stage II, 62 as stage IIIA /B, and 17 as stage IIIC. Five patients died of cancer relapse (4.1%),
and 18 cases had recurrence of disease (14.9%), to date. No port-site recurrence was detected. Overall five-year survival
was 95.7% in stage II, 84.1% in stage IIIA/B, 70.0% in stage IIIC. Meanwhile disease-free five-year survival was 75.6% in
stage II, 80.1% in stage IIIA/B, and 66.8% in stage IIIC. No significant difference was observed between stages, in terms
of either overall or disease-free survival.
Conclusion Although further evaluation is required, laparoscopic surgery for stage II/III colorectal cancer is safe and would be an oncologically
adequate procedure. 相似文献
