十二指肠溃疡患者胃上皮化生与幽门螺杆菌关系的研究

目的 研究十二指肠溃疡患者胃上皮化生和幽门螺杆菌的关系。方法 收集门诊行上消化道胃镜检查确诊的十二指肠溃疡患者70例，另选胃和十二指肠黏膜正常患者55例为对照组。用快速尿素酶法和幽门活组织检查半定量法检测幽门螺杆菌(Hp)，苏木素一伊红染色和Schiff过碘酸染色半定量法检测十二指肠球部胃上皮化生。结果 十二指肠溃疡患者与对照组相比，十二指肠球部胃上皮化生检出率高；十二指肠球部胃上皮化生检出率和评分与胃幽门部Hp的检出率和评分无相关关系。结论 Hp不是十二指肠黏膜胃上皮化生的决定因素，也不是十二指肠黏膜胃上皮化生范围得以扩展的因素。十二指肠溃疡病本身的一些特点是十二指肠黏膜胃上皮化生的主要因素。

BorrmannⅣ型胃癌的临床特征和外科治疗

目的探讨BorrmannⅣ型胃癌的临床特征和治疗方法。方法回顾性总结29例BorrmannⅣ型胃癌的临床资料,分析本型胃癌的临床表现、病理特点以及手术治疗的特殊性。结果全部患者均有上腹饱胀、隐痛不适、食欲不振,同时伴有明显的进行性消瘦,短期内体重明显减轻等临床症状。术前病理确诊为本型胃癌者24例。5例患者胃镜诊断为浅表型胃炎。获根治性切除22例,姑息性远侧胃切除者3例,放弃手术者4例。其1、2、3年生存率分别为38.9%、8.3%、0%。结论(1)BorrmannⅣ型胃癌是一种恶性程度极高的胃癌,其具有独特的生物学特性,治疗效果差,生存期短,预后不佳。(2)对BorrmannⅣ型胃癌应强调以根治性全胃切除和联合脏器切除为主的综合治疗方法。     

Studies on the effects of Pluchea indica less root extract on gastroduodenal ulcer models in rats and guineapigs

The methanolic fraction of P. indica root extract was found to possess significant antiulcer activity in different experimental animal models. In preventive antiulcer tests, significant protective actions in acetylsalicylic acid, serotonin and indomethacin-induced gastric lesions were observed in experimental rats. The extract also afforded significant protection to chemically-induced duodenal lesion in guineapigs. Significant enhancement of healing process in acetic acid-induced chronic gastric lesions were also observed in the extract-treated animals.     

Retrospective review of the preoperative biliary and gastrointestinal evaluation for gastric bypass surgery

BACKGROUND: The purpose of this study was to analyze the frequency and results of preoperative biliary and gastrointestinal (GI) evaluation of patients undergoing Roux-en-Y gastric bypass (RYGB). METHODS: Retrospective review of the preoperative evaluation of 144 consecutive RYGB patients. RESULTS: Cholecystectomy had already been performed in 43 (30%) patients; 22% of those patients with an intact gallbladder had cholelithiasis. Ten patients (7%) had an upper GI x-ray (UGI), and 94 patients (65%) had an esophagogastroduodenoscopy (EGD). Abnormalities were found in 40% of the UGIs and 84% of the EGDs. A total of 96 patients (67%) were tested for Helicobacter pylori; 11% were positive. Twenty-one patients (15%) underwent preoperative colonoscopy; 48% were abnormal, but most of the abnormalities were not clinically significant. Three patients had barium enema x-ray, which was normal in all cases. CONCLUSIONS: The preoperative biliary and GI evaluation of bariatric surgery patients should include a routine ultrasound of the gallbladder. Routine preoperative EGD will detect a significant number of abnormalities that should be treated, but should rarely alter the bariatric surgical procedure or result in denial of bariatric surgery. Many abnormalities will be asymptomatic. Patients should be routinely screened for H. pylori and, if positive, treated before bariatric surgery. Lower GI evaluation should be performed selectively based on the patient's symptoms, physical findings, and guidelines for colorectal cancer and polyp screening.     

不透X线标志物法对胃排空及胃肠通过时间的测定

目的:评价自制不透X线标志物的临床应用价值,并确定正常人胃排空及胃肠道通过时间的正常值。方法:采用X线法对60例健康志愿者餐后1 h、2 h3、h的胃排空及24 h4、8 h肠道标志物排出情况进行观察。结果:正常人标准餐后3 h胃排空率为41.1±30.0%,24 h和48 h肠道标志物排出率分别为73.5±29.8%、99.0±20.9%。结论:自制的标志物具有良好的屏蔽功能;X线法胃排空及胃肠通过时间测定方法简单实用,值得临床推广。     

128例老年胃癌患者围手术期临床特点分析及护理对策

目的：提高对老年胃癌患者围术期护理的认识。方法：对128例≥65岁胃癌患者与同期〈65岁212例胃癌患者围术期各方面资料进行对比分析。结果：≥65岁组术前合并症多，全胃及联合脏器切除比例高、创伤大，术后非手术相关并发症多，患者文化水平较低，社会支持水平低。结论：对老年胃癌患者应重视术前的全面评估和充分准备，争取和利用患者的社会支持系统，采取灵活多样的形式进行健康教育，术后重视呼吸系统、心血管系统并发症及手术相关并发症（吻合口瘙、胃排空障碍、胰腺炎、胸腔积液或腹腔积液等）的预防和护理。
