Bleeding from gastric ulcer halted by laparoscopic suture ligation

In a 48-year-old Japanese man there was an uncontrollable and recurrent bleeding from a gastric ulcer and laparoscopic surgery was done. Two cannulae were placed in the gastric cavity through the abdominal wall and suture ligation of the bleeding vessel at the posterior wall of the stomach was done under videovisual control with endoscopic guidance. The bleeding ceased, complications were nil, and he remains well.This article reports on surgery done to repair uncontrollable, recurrent bleeding from a gastric ulcer. Two cannulae were placed in the gastric cavity through the abdominal wall and suture of the vessel at the posterior wall of the stomach was done with videovisual control and endoscopic guidance. This approach is concluded to have supplied minimal-access surgery, cost effectiveness, early discharge, less pain, and doctor-patient satisfaction.

Gd-DOTA as a gastrointestinal contrast agent for gastric emptying measurements with MRI

Current MR meal markers may interfere with gastric motility and secretion restricting the use of MRI in the measurement of gastric physiology. We therefore evaluated Gd-DOTA as a liquid phase marker, in vitro by determining dissociation, and adherence to the solids, and in vivo by simultaneous MRI (0.35 T scanner, multiple T₁-weighted sections of the upper abdomen) and double indicator (perfusion marker PEG 4000, meal marker ^99mTc-DTPA) measurements of emptying and secretion, following ingestion of 500 ml 10% glucose. In vitro Gd-DOTA was stable at a pH > 2 with < 2% dissociation at 24 h during incubation with HCI. Dissociation during incubation with HCI was linearly dependent on H⁺ concentration (0.77 < pH < 2.02). Less Gd-DOTA was absorbed onto the solid phase than ^99mTc-DTPA (25% cf 36%). in vivo Gd-DOTA marked gastric contents provided strong positive contrast. Similar emptying curves were observed with both MRI and double-indicator techniques (r = 0.987, P < 0.001). Gd-DOTA has the potential to be a useful liquid phase contrast agent in MR studies on gastric function.     

胃癌组织中KAI1、nm23及P53的表达及其临床意义

目的:探讨正常胃黏膜、不典型增生胃黏膜及癌组织中KAI1、nm23及P53蛋白的表达．方法:应用SP法免疫组化检测22例正常胃黏膜,65例不典型增生胃黏膜及74N胃癌组织中的KAI1、nm23及P53蛋白的表达．结果:正常胃黏膜、不典型增生胃黏膜及胃癌组织中,KAI1和nm23阳性率呈降低趋势,组间差异性有统计学意义(x2=20．885, P<0．001;x2=29．133,P<0．05):P53蛋白阳性表达率呈增加趋势,组间差异性有统计学意义(x2=21．954,P<0．001)．Fisher精确概率检验显示:在胃癌组中不同的浸润深度、有无淋巴结转移和脉管侵犯组内KAI1、nm23及 P53组阳性表达率的差异性有统计学意义(x2 =20．885,P<0．001;x2=29．133,P<0．05;x2= 21．954,P<0．001);而在年龄、性别组间的差异性无统计学意义．Spearman等级相关分析显示 KAI1与nm23表达呈正相关(r=0．859,P<0．05); KAI1与P53表达呈负相关(r=-0．859,P<0．05), nm23与P53表达呈负相关(r=-0．874,P<0．05) 结论:抑癌基因KAI1与nm23的缺失以及P53 蛋白的过表达可能是胃癌发生、发展及浸润和转移的重要原因之一．     

紫杉醇联合希罗达治疗晚期胃癌的初步观察

机械通气患者体位改变插入胃管效果与分析

目的提高有创机械通气患者插入胃管的成功率,减少因反复插管所致的并发症,减轻患者痛苦,提高护士的工作效率。方法把有创机械通气的60例患者,随机分为观察组30例和对照组30例,观察组采取改变常规的“去枕头后仰位”为“抬高床头70°~80°角,头正位”插入胃管,对照组采取常规的去枕头后仰卧位的体位方法插入胃管。结果对照组一次插管成功率为6.66%,观察组一次插管成功率为90%,经统计学分析,差异有显著意义(P<0.01)。结论有创机械通气患者改变常规的“去枕头后仰位”为“抬高床头70°~80°角,头正位”后一次插入胃管成功率明显提高。

Simultaneous noninvasive evaluation of gastric emptying and orocaecal transit times

Summary The aim of the study was to use a novel combination of two methods for the simultaneous evaluation of two effects of oral cisapride in 10 diabetic patients with autonomic neuropathy; gastric emptying time was measured by following radio-opaque markers and orocaecal transit time by the sulphasalazine-sulphapridine method. The study was of double-blind, randomized, placebo-controlled, cross-over design.It was possible to evaluate the effect of a prokinetic drug on gastric emptying and orocaecal transit times using these two noninvasive techniques at the same time. Cisapride significantly reduced both the gastric emptying (1.2 h versus 2.1 h) and orocaecal tansit (5.9 h versus 7.7 h) times.
