肠易激综合征辨证分析

肠易激综合征（IBS）是一组持续存在或反复发作的临床症候群,主要症状有腹痛、腹胀、排便习惯改变和大便性状异常、黏液便等,经检查排除可引起这些症状的器质性疾病。临床分为肝木乘脾型腹泻、脾胃虚弱型腹泻、脾肾阳虚型腹泻、肝郁脾虚型便秘四型,根据临床辨证分别施以不同治法,不同方药治疗,有显著疗效。同时,教育患者平时养成良好的饮食卫生习惯,不饮生水,不食生冷瓜果,忌食辛辣、油腻、肥厚之品,保持心情舒畅,怡情悦志,注意保暖,可加强疗效,防止复发。     

Thyroid Artery Erosion by Esophageal Cancer: Management with Interventional Radiology

Management of upper gastrointestinal bleeding because of erosion of vessels by esophageal cancer may be challenging. We present herein the angiographic images of a 49-year-old patient who was admitted with massive bleeding from a tumor-eroded inferior thyroid artery. Attempts to control the bleeding by means of flexible endoscopy and insertion of a Sengstaken–Blakemore tube had failed. The diagnosis was impressively demonstrated by multislice computed tomography with intravenous contrast in the arterial phase and multiplanar reconstructions (computed tomography angiography) and by digital subtraction angiography. The bleeding was successfully treated with superselective catheterization and coiling of the eroded vessel.     

术后早期肠内营养对食管癌患者肠黏膜屏障功能的影响

目的 探讨食管癌患者术后早期施行肠内营养支持对胃肠道黏膜屏障的保护作用. 方法术前3个月内体重下降超过患病前体重20%的食管癌患者56例,按所给营养方法不同分为肠内营养组(n=30)和肠外营养组(n=26),观察两组患者的临床结果,分别于术后第1、4和8天测定两组患者尿乳果糖与甘露醇的比值、血浆内毒素、肿瘤坏死因子(TNF)、胃泌素和谷氨酰胺水平. 结果肠内营养组患者术后体重减轻较少,感染性并发症发生较少(P<0.01,0.05).术后第4天和8天,肠内营养组尿乳果糖与甘露醇比值、血浆内毒素和TNF较肠外营养组低(P<0.01),胃泌素、谷氨酰胺较肠外营养组高(P<0.01). 结论食管癌患者术后早期肠内营养对肠道黏膜屏障功能具有一定的保护作用,有可能减少术后感染性并发症的发生.     

Robotic-assisted heller myotomy versus laparoscopic heller myotomy for the treatment of esophageal achalasia: multicenter study

Laparoscopic Heller myotomy (LHM) has become the standard treatment option for achalasia. The incidence of esophageal perforation reported is about 5%–10%. Robotically assisted Heller myotomy (RAHM) is emerging as a safe alternative to LHM. Data comparing the two approaches are scant. The aim of this study was to compare RAHM with LHM in terms of efficacy and safety for treatment of achalasia. A total of 121 patients underwent surgical treatment of achalasia at three institutions. A retrospective review of prospectively collected perioperative data was performed. Patients were divided into two groups: group A (RAHM), 59 patients, and group B (LHM), 62 patients. All the operations were completed using minimally invasive techniques. There were 63 women and 58 men, with a mean age of 45 ±19 years (14–82 years). Fifty-one percent of patients in group A and 95% of patients in group B reported weight loss. Duration of symptoms was equal for both groups. Dysphagia was the main complaint in both groups (P = NS). There was no difference in preoperative endoscopic treatment in both groups (44% versus 27%, P = NS). Operative time was significantly shorter for LHM in the first half of the experience (141 ± 49 versus 122 ± 44 minutes, P < .05). However, in the last 30 cases there was no difference in operative time between the groups (P = NS). Intraoperative complications (esophageal perforation) were more frequent in group B (16% versus 0%). The incidence of postoperative heartburn did not differ by group. There were no deaths. At 18 and 22 months, 92% and 90% of patients had relief of their dysphagia. This study suggests that RAHM is safer than LHM, because it decreases the incidence of esophageal perforation to 0%, even in patients who had previous treatment. At short-term follow-up, relief of dysphagia was equally achieved in both groups.

胃癌累及胰腺的外科治疗与预后(附120例报告)

目的探讨胃癌累及胰腺的外科治疗方法与预后的关系。方法回顾性分析我院1984年6月～2003年10月手术治疗累及胰腺的胃癌120例。结果本组120例中,根治切除组41例,姑息切除组23例,未切除组56例。根治组41例中经病理证实胰腺有癌细胞浸润者30例,占73.2%,淋巴结转移率为85.4%。其中No10、11淋巴结转移率为73.1%。术后102例得到随访,随访率为85%,1、3、5年的生存率分别为:根治切除组为73%、37%、17%,姑息切除组为22%、9%、4%,未切除组为9%、2%、0%。根治切除组1,3年生存率明显高于姑息性切除组和未切除组(P<0.05),5年生存率明显高于未切除组(P<0.01),但与姑息性切除组无显著性差异。姑息性切除组和未切除组1、3年生存率无显著性差异,但5年生存率明显高于未切除组(P<0.01)。结论胃癌累及胰腺的根治切除可提高1,3年生存率,选择合适的适应征是关键。姑息切除有助于改善生存质量,对改善预后意义不大。

目的 观察对中晚期食管癌患者同步放化疗,疗效及毒副作用.方法 中晚期食管癌120例,随机分放化疗组60例(简称放化组)和单纯放疗组60例(简称单放组).放疗采用常规分割,DT40 Gy后缩小照射野,避开脊髓斜野照射,加量DT20～30 Gy,6～7周完成.放化组放疗1、4周后应用顺铂(DDP)20 mg/d、亚叶酸钙(CF)0.1 g/d,CF静脉滴注1/2量时5-氟尿嘧啶(5-Fu)500 mg/d静脉滴注,连续5 d为1个周期,化疗当天进行放疗.结果 放化组与单放组1、2、3年生存率分别为67%、46%、34%和52%、38%、24%;放射性肺炎分别为14例和12例;外周血细胞下降分别为26例和17例;胃肠道反应分别为25例和9例;死亡分别为38例和48例.两组治疗效果比较差异有统计学意义(P＜0.05).结论 放疗同步PLF方案化疗治疗中晚期食管癌生存率高,毒副作用及不良反应低.     

雷公藤内酯对人胃癌细胞株FGC_(85)杀伤作用的光镜和电镜观察

本文应用核苷掺入技术及电镜观察首次证实雷公藤内酯对人胃癌细胞株 FGC_(85)的杀伤作用。用药早期,细胞数,分裂指数及 DNA,RNA 合成无明显变化,但出现核仁脱粒及核仁破碎等变化;晚期,电镜观察发现细胞以凋落方式死亡,药物主要作用于间期细胞,其杀伤机构的始动环节可能与核酸代谢障碍无关。     

Treatment of a malignant esophageal fistula with a Gore-Tex-covered flexible nitinol stent

In order to treat fistulated esophageal cancer using a flexible stent, a covered flexible stent was constructed by wrapping a nitinol stent with a thin sheet of Gore-Tex, preserving the stents original advantages of flexibility and a low-profile introducer system. This stent was used to perform standard radiotherapy in a case of fistulated esophageal cancer.
