功能性消化不良胆囊功能及其与胃排空相关性的初步探讨

为了解功能性消化不良(Functional dyspepsia.FD)患者是否存在胆囊功能障碍及胆囊功能与胃运动功能之间的相关性,我们对16例FD患者及8名健康人进行了B超下胆囊功能测定及核素胃排空检查.结果显示:FD患者2小时胃排空率为56.38±14.93%,半排空时间为104.72±22.73min,正常人胃排空率为70.75±11.44%,半排空时间为83.60±19.99min.FD组的胃排空明显延迟(P<0.001).FD组胆囊排空率<30%者较正常人明显增多(P<0.05),而将FD组进一步分为胃排空异常及胃排空正常组后发现胃排空正常的FD病人胆囊功能与健康人无差异,而胃排空延迟的FD病人的胆囊排空率亦明显降低,与正常人及胃排空正常的FD病人相比均有显著差异(P<0.05).结果表明功能性消化不良患者有胆囊排空功能的减弱,这种减弱与胃排空功能障碍有关,其相关的机制有待于进一步研究.     

针刺足三里对功能性消化不良患者血浆胃肠激素的影响

目的：探讨针刺足三里对功能性消化不良（FD）患者血浆胃肠激素的影响,以及胃肠激素在FD发病中的可能作用及其临床意义。方法：对20例FD患者针刺前后各抽取血液5ml,采用放免分析法测定患者空腹血浆胃动素（MLT）、胃泌素（GAS）、生长抑素（SS）含量。结果：针刺足三里后,血浆MLT含量明显上升,与针前比较差异有非常显著性意义（P＜0．01）;SS含量明显降低,与针前比较差异有显著性意义（P＜0．05）;FD患者基础血浆MLT明显低于健康者。结论：针刺足三里对FD患者胃肠激素具有良好的调整作用,并提示胃肠激素可能参与了FD的发病或病理生理过程。     

胃排空障碍与功能性消化不良相关性的研究

目的：探讨胃排空障碍与功能性消化不良（FD）之间的关系。方法：以双核素标记试餐SPECT技术检测了22例FD患者的液、固体食物胃排空和食物胃内分布，并以实时超声检测了72例FD患者在西沙必利治疗前后的液体胃排空变化，分析这些变化与症状积分变化的相关性．结果：68．2％的FD患者存在胃排空障碍，以固体胃排空延迟为主，单纯液体排空障碍较少；摄食后比对照组有更多的食物滞留于远端胃内，然而，延迟的胃排空和改变了的固体食物胃内分布与FD的主要症状无显著相关性。西沙必利明显缩短FD患者的液体胃排空时间，改善其中部分患者的临床症状，而另一部分患者的症状无明显缓解．结论：西沙必利改善FD症状并非完全依赖于其促排空效应，胃排空障碍与FD之间缺乏必然的联系，它们可能是同一病生基础的两种不同表现．     

符合罗马Ⅲ标准的功能性消化不良患者固体胃排空功能研究

背景：罗马Ⅲ标准对功能性消化不良（FD）的定义作了更新和修订，相应FD患者人群亦发生改变。目的：研究符合罗马Ⅲ标准的FD患者的固体胃排空功能，以及新的FD症状谱和分型与固体胃排空功能之间的关系。方法：对36例符合罗马Ⅲ标准的FD患者和32名健康志愿者行^99Tc固体胃排空试验。比较不同症状分型FD患者的固体胃排空功能，分析固体胃排空功能与罗马Ⅲ标准中FD症状的相关性。结果：10例（27．8％）FD患者固体胃半排空时间超过正常上限，9例（25．0％）2h残留率高于正常上限。餐后不适综合征（PDS）、上腹痛综合征（EPS）和PDS＋EPS型FD患者固体胃半排空时间分别为（150．3±40．2）min、（118．3±25．1）min和（150．5±51．2）min，三组间差异无统计学意义（P=0．126）。餐后饱胀不适症状与固体胃半排空时间和2h残留率均呈线性正相关．相关系数分别为11．5（P=0．043）和0．045（P=0．040）。结论：本组27．8％的FD患者存在固体胃排空延迟。PDS和PDS＋EPS型FD的固体胃半排空时间有长于EPS的趋势。FD患者的餐后饱胀不适症状与固体胃排空延迟有关，固体胃排空延迟是符合罗马Ⅲ标准的FD患者的病理生理机制之一。

Electrogastrography Before and After a High-Caloric,Liquid Test Meal in Healthy Volunteers and Patients with Severe Functional Dyspepsia

Background: The cutaneous recording of gastric electric rhythm, so-called electrogastrography (EGG), has been purported as a non-invasive method for studying patients with functional dyspepsia and unexplained nausea and vomiting. The aims of this study were to determine normal values for EGG characteristics before and after a liquid, high-caloric test meal and to investigate whether EGG could discriminate between patients with functional dyspepsia and normal controls. Methods: In studying 20 healthy volunteers and 10 patients with functional dyspepsia, we recorded gastric electrical activity during the 30 min before and after a liquid 1.0-1.5 kcal/ml test meal. Satiety before and after the meal was estimated on a 10-point scale. EGG was analysed regarding dominant frequency, instability of the dominant frequency, power ratio and percentage activity in the normal frequency range. Results: The mean ( ± s ) caloric intake in patients with functional dyspepsia (286 ± 160 kcal) was significantly lower ( P < 0.001) than in healthy volunteers (610 ± 211 kcal). The patients reported a more pronounced feeling of satiety before the test meal (5.6 ± 3.2) compared to healthy volunteers (3.6 ± 1.2, P < 0.05), but at the end of the test meal there was no difference in satiety (7.9 ± 2.5 versus 7.7 ± 1.0). However, none of the EGG parameters showed any difference between patients and healthy volunteers. Conclusions: EGG before and after a high-caloric test meal showed large variation in healthy subjects and seemed to be of little value for differentiating between healthy individuals and patients with functional dyspepsia.

Reproducibility of gastric myoelectrical activity and the water load test in patients with dysmotility-like dyspepsia symptoms and in control subjects

Gastric dysrhythmias and normal gastric myoelectrical activity have been recorded in patients with functional dyspepsia. The aim of this study was to determine the reproducibility of gastric myoelectrical patterns and responses to a water load in patients with dysmotility-like functional dyspepsia and healthy control subjects. We studied 24 patients with dysmotility-like functional dyspepsia and 24 age-matched control subjects. Gastric myoelectrical activity was assessed using cutaneous electrodes to record electrogastrograms (EGGs) before and after the subjects ingested water until full. The EGGs with water load tests were repeated 1 week apart. The patients ingested significantly smaller volumes of water at both week 1 and 2 (358 +/- 26 mL and 349 +/- 30 mL) compared to control subjects (557 +/- 35 mL and 560 +/- 27 mL, p < 0.01). Gastric dysrhythmias were found in 4 of 24 (16.7%) control subjects at each visit and in 14 (58%) and 12 (50%) of the dyspeptic patients at week 1 and 2, respectively. Of 14 patients, 2 (14.3%) had gastric dysrhythmias at week 1 but had normal gastric rhythms at week 2. Thus, reproducibility was 100% in the control subjects and 91.7% in the patients. In conclusion, some variability in EGG pattern occurred, but gastric myoelectrical activity and responses to the water load test were generally consistent and reproducible in patients with dysmotility-like functional dyspepsia and in healthy control subjects.     

50例功能性消化不良患者空腹体表胃电图分析

目的：观察功能性消化不良患者空腹体表胃电图（EGC）变化情况。方法;对临床诊断为功能性消化不良的50例患者空腹体表EGG描记（实验组）。对照组为35例健康查体者,亦行空腹体表EGG描记,将两组描记结果进行对比分析。结果：50例功能性消化不良的患者中有38例（76％）体表EGG异常,主要表现为胃电节律过缓或过速。而对照组仅有5例（14．3％）体表EGG异常。两组差异显著（P＜0．05）。结论：空腹体表EGG描记对功能性消化不良具有协助诊断意义,它对进一步了解胃动力紊乱性疾病的病理机制亦有帮助。     

Gastric myoelectrical activity and gastric emptying in patients with functional dyspepsia

OBJECTIVES: The aims of this study were to investigate gastric myoelectrical activity and gastric emptying (GE) and their relationship in patients with functional dyspepsia. METHODS: The study was conducted in 15 healthy volunteers (six women, nine men, mean age: 42 yr) and 15 patients (13 women, two men, mean age: 43 yr) with functional dyspepsia. Gastric myoelectrical activity was recorded using cutaneous electrogastrography (EGG) for 30 min in the fasting state and for 120 min simultaneously with GE monitoring after an isotope-labeled solid meal. The anterior/posterior images of the stomach were taken using a technetium scanner immediately after eating, and then at 1, 2, and 4 h to determine the percentage of gastric retention. The dominant frequency of the EGG, the change of the postprandial EGG peak power (deltaP), and the percentage of normal 2-4 cycles/min (cpm) slow waves during each recording session were calculated and compared between the patients and healthy subjects. RESULTS: The patients had a significantly lower mean percentage of 2-4 cpm slow waves, both in the fed state and in the fasting state, than did healthy subjects. Compared to the EGG in the fasting state, a significant increase of the EGG dominant frequency in the fed state was observed in healthy subjects but not in the patients. The mean postprandial EGG power increase in the patients was substantially less than in the healthy subjects during the first postprandial hour but similar during the second postprandial hour. The mean percentage of gastric retention in patients is substantially higher than in the healthy subjects, both at 2 h after eating and at 4 h after eating. Of 15 patients, nine (60%) had delayed GE (gastric retention at 2 h >50%) and 10 (66%) had abnormal EGGs (percentage of 2-4 cpm <70% and/or deltaP < 0). Eight of these 10 patients (80%) with abnormal EGGs had delayed GE. CONCLUSIONS: A high proportion of adult patients (60%) with functional dyspepsia have abnormally slow GE and abnormalities in gastric myoelectrical activity.     

Electrogastrography associated with symptomatic changes after prokinetic drug treatment for functional dyspepsia

AIM:To evaluate the effect of prokinetic drugs on electrogastrography(EGG) parameters according to symptomatic changes in patients with functional dyspepsia(FD).METHODS:Seventy-four patients with FD were prospectively enrolled in this study between December 2006 and December 2010.We surveyed the patients using a questionnaire on dyspeptic symptoms before and after an 8-wk course of prokinetic drug treatment.We also measured cutaneous pre-prandial and postprandial EGG recordings including percentage of gastric waves(normogastria,bradygastria,tachygastria),dominant frequency(DF),dominant power(DP),dominant frequency instability coefficient(DFIC),dominant power instability coefficient(DPIC),and the ratio of post-prandial to fasting in DP before and after the 8-wk course of prokinetic drug treatment.RESULTS:Fifty-two patients(70%) achieved symptomatic improvement after prokinetic drug treatment.Patients who had normal gastric slow waves showed symptom improvement group after treatment.Postprandial DF showed a downward trend in the symptom improvement group,especially in the itopride group.Post-prandial DP was increased regardless of symptom improvement,especially in the itopride group and mosapride group.Post-prandial DFIC and DPIC in the symptom improvement group were significantly increased after the treatment.The EGG power ratio was increased after treatment in the symptom improvement group(0.50 ± 0.70 vs 0.93 ± 1.77,P = 0.002),especially in the itopride and levosulpiride groups.CONCLUSION:Prokinetics could improve the symptoms of FD by regulating gastric myoelectrical activity,and EGG could be a useful tool in evaluating the effects of various prokinetics.     

Edrophonium Provocative Testing During Electrogastrography (EGG) (Effects on Dyspeptic Symptoms and the EGG)

The aim of this study was to determine whetheredrophonium induces dyspeptic symptoms and/or gastricmyoelectric changes in normal subjects and patients withfunctional dyspepsia. Eighteen normal controls and 28 patients with functional dyspepsiaunderwent electrogastrography (EGG) with edrophoniumadministration. After EGG recording with 1-hr fastingand 2-hr postprandial periods, subjects received anintravenous infusion of saline (placebo) followed byedrophonium 10 mg. After each injection, the EGG wasrecorded for 15 min and symptoms scored. Patients withfunctional dyspepsia had significantly more frequent gastrointestinal symptoms in response toedrophonium than normal controls. Edrophonium had noeffect on EGG dominant frequency, but increased thepower of the dominant frequency in both controls anddyspeptic patients. In the dyspeptic patients,reproduction of the patient's symptoms was associatedwith an increase in the power of the dominant frequency,whereas when no symptoms were produced, there was nochange in power. Overall, 21 of 28 dyspeptic patients(75%) had either an abnormal baseline EGG (N = 10) or anormal EGG and positive edrophonium test (N = 11). Inconclusion, edrophonium administration can reproduce symptoms in some dyspeptic patients.Symptoms after edrophonium administration may be relatedto either more vigorous gastric contractions and/orincreased visceral perception of normal gastric contractions.     

Impact of bitter taste on gastric motility

BACKGROUND: Unexplained nausea and vomiting is often associated with delayed gastric emptying in patients with functional dyspepsia. We hypothesized that the experience of an unpleasant, nauseating taste could lead to a delay in gastric emptying. METHODS: Sixteen healthy women consumed a bland liquid test meal on three separate study days. On two of the study days subjects sham fed either a bitter tasting, modified Slim-Fast bar or one with a pleasant strawberry flavour. The time for 50% gastric emptying (GE(50)) was non-invasively assessed by electrical impedance tomography and antral motility by electrogastrography (EGG). RESULTS: Gastric emptying was significantly delayed by sham feeding the bitter compared with the pleasant bar, GE(50) 24.7+/-3.9 versus 17.2+/-1.8 min, P<0.05. EGG power rose significantly during both the pleasant (basal 1.46+/-0.07 to 2.33+/-0.14 log(10) microV(2)/min, P=0.000) and the bitter sham feed (basal 1.64+/-0.09 to 2.35+/-0.11 log(10) microV(2)/min, P=0.000). CONCLUSION: An unpleasant bitter taste delays gastric emptying but does not significantly impair antral motility.     

Electrogastrography in patients with Roux-en-Y reconstruction after previous Billroth gastrectomy

BACKGROUND/AIMS: The aim of this prospective study was to characterize gastric myoelectrical activity in patients with Roux-en-Y reconstruction after previous Billroth gastrectomy. METHODOLOGY: Thirteen patients entered the study (6 men and 7 women, aged 35-57). The mean time from Roux-en-Y reconstruction to electrogastrography (EGG) recording was 5 years. Surface cutaneous EGG was recorded using a Digitrapper EGG in the morning both fasting and after a standard solid test meal. All patients assessed their dyspeptic symptoms at the time of EGG in a semi-quantitative subjective scale. RESULTS: EGG was abnormal in all studied patients (but one postprandial recording). Dyspepsia was not meal-related and was not more severe in Helicobacter pylori positive patients. There was a significant negative correlation between time from Roux-en-Y reconstruction to EGG recording and bradygastria percent activity, both fasted and postprandial (r = -0.576; p = 0.0022). There was an inverse trend between severity of dyspepsia and normal slow-wave rhythm percent activity. Older patients tended to have more severe dyspepsia. CONCLUSIONS: The results of this study suggest that abnormal EGG recording is associated with dyspepsia in patients after Roux-en-Y reconstruction.     

阿米替林对功能性消化不良症状及胃动力的作用

研究功能性消化不良（ＦＤ）患者的胃排空和胃电特性以及阿米替林对ＦＤ的疗效。方法：用双同位素标记ＳＰＥＣＴ技术和体表胃电图检测４２例ＦＤ患者服用小剂量阿米替林前后胃运动功能的变化。结果：ＦＤ组和对照组液相排空曲线相似，半排空时间（Ｔ５０）差异无显著性；ＦＤ组固相Ｔ５０较对照组显著延长，胃电节律紊乱率及餐后振幅降低率较对照组显著增加。阿米替林治疗４周后，ＦＤ患者的临床症状显著改善，但胃排空异常率及胃电
