【Abstract】 Objective To introduce the recent studies about the lymph node-targeted chemotherapy for gastric carcinoma. Methods The literatures on the lymph node-targeted chemotherapy for gastric carcinoma in recent years were collected and reviewed. Results The lymph node-targeted chemotherapy for gastric carcinoma was effective because it couled improve the drug concentrations in regional lymph node. Conclusion As a part of multiple treatments for gastric carcinoma, lymph node-targeted chemotherapy will be further developed.
ObjectiveTo summarize the research progression of Doppler-guided hemorrhoidal artery ligation in the treatment of hemorrhoids. MethodsThe related literatures in recent years were reviewed, and to investigate the operation principle, operation process, the indications and effects, and existing problems of Doppler-guided hemorrhoidal artery ligation. ResultsThe surgical principle of Doppler-guided hemorrhoidal artery ligation make use of Doppler ultrasound looking for hemorrhoidal artery, and ligation it directly.It's best indication is Ⅱ or Ⅲ degree hemorrhoids or mixed hemorrhoid with grade Ⅰ or Ⅲ mainly, especially for bleeding hemorrhoids disease curative effect is better.This surgical method has lots of advantages, such as less invasive, quick recovery, and low incidence of complications.But it is no significant treatment effect for the external hemorrhoids, therefore, the procedure does not apply to external hemo-rrhoids and mixed hemorrhoids dominated by external hemorrhoids. ConclusionsDoppler-guided hemorrhoidal artery ligation has the advantage of minimally invasive, it is a safe and effective treatment for Ⅱ and Ⅲ degree internal hemorr-hoids or Ⅱ and Ⅲ degree mixed hemorrhoids dominated by internal hemorrhoids.
目的 总结我科2002年3月至2005年10月收治的下肢深静脉血栓形成(deep vein thrombosis,DVT)患者的诊治经验.方法 本组下肢DVT患者275例,患肢294条.男134例,女141例,年龄14～92岁,平均(50.76±16.43)岁.单侧下肢DVT 256例(左侧159例,右侧97例),19例为双下肢DVT(其中有8例是仅一侧肢体有临床表现); 属混合型194条,中央型74条,周围型26条.行彩色多普勒或静脉造影检查了解血栓部位及范围; 对怀疑有肺动脉栓塞(pulmonary embolism, PE)者行肺部增强CT扫描.治疗包括抗凝、溶栓、祛聚、梯度压力静脉弹力袜以及对症处理.对反复发生PE、存在抗凝治疗禁忌证、需要手术取栓、下肢静脉存在悬浮游离血栓者安置下腔静脉滤器.对发生股青肿患者行手术取栓.疗效评价: 住院期间观察症状变化,监测膝关节上、下15 cm处周径; 对随访患者行CEAP(clinical-etiology-anatomic-pathophysiologic)临床表现分级、功能障碍评分(venous disability score, VDS).结果 本组DVT常见的危险因素包括活动受限史、2周以内有手术史、恶性肿瘤及外伤史.本组患肢主要临床表现包括: 肿胀、疼痛、皮温增高、皮肤暗红、浅静脉迂曲等.并发症: PE 9例,股青肿2例,下腔静脉阻塞综合征3例.275例中2例行手术取栓,25例安置下腔静脉滤器.本组患者症状经治疗后1～5 d开始缓解,出院时膝关节上、下周径较入院时明显缩小(P＜0.05).随访时间6个月～3年,195例(70.9%)的201条(68.4%)患肢获得随访,患肢CEAP分级: C0级78条,C1级53条,C2级16条,C3级20条,C4级15条,C5级11条,C6级8条; VDS评分: 0分77例,1分66例,2分33例,3分19例.结论 下肢DVT的诊断中应注意对危险因素以及无症状的DVT的搜寻; 早期治疗以非手术治疗为主,通过抗凝、溶栓等综合治疗可以达到满意效果; 在早期如发生股青肿应及时手术治疗; 有选择地安置下腔静脉滤器可防止PE的发生; 后期应根据病情特点确定治疗方案和疗程.
Objective To summarize the research progress of transanal total mesorectal excision (TaTME) for rectal cancer. Methods The literatures about current status, limitations, and prospects of TaTME in China and abroad were collected to make an reviewe. Results TaTME is conformed to the principle of total mesorectal excision (TME), by using the ‘bottom-up’ approach and assisting in the laparoscopic technique platform, to ensure an adequate oncological distal margin, and it could improve the quality of the mesorectum specimens, reduce the circumferential margin involvement rate, afford more precise autonomic nerve preservation rate, and increase sphincter preservation rate. But it is also facing new complications, oncological and functional outcomes problems. Conclusions Although the experience with TaTME remains limited, the safety, feasibility, and short-term outcomes are acceptable. Nevertheless, there is a need for multicenter, large sample size, and long-term follow-up clinical studies focusing on the long-term outcomes to further improve the oncological safety of TaTME, before widespread application can be recommended.
Objective To explore the diagnostic methods, therapy and the prognostic factors for the ruptured abdominal aortic aneurysm (RAAA). Methods The clinical data of 23 patients (males 15, females 8, age range 35-78, mean age 65) with RAAA below the level of renal arteries, who were treated with surgery, were collected from April 1999 to December 2005 and were analyzed retrospectively. Seven cases had a history of RAAA, 6 cases had pulsating abdominal masses; 15 cases were diagnosed by emergency Doppler ultrasonic examination or CT. All of the patients underwent emergency surgical operation: The ruptures of the abdominal aorta below the level of renal arteries were obstructed by using clamp ring or using transluminal ballon according to conditions of each patient. The aritficial vascular graft was then taken after the control of hemorrhage. Results There were 9 (39%) patients died within 30 d after the emergency operation. The causes of death included acute renal failure because of hemorrhagic shock (4 cases), multiple organ failure (3 cases), and respiratory-circulatory failure (2 cases).Conclusion Surgery may be an effective treatment for RAAA. The critical step of the operation was to control hemorrhage by obstructing the proximal end of the aortic rupture according to the conditions of each patient. The main postoperative complications and causes of death include acute cardiovascular and cerebrovascular diseases, renal failure and pneumonia.
