Measurement of gastric emptying in dyspeptic patients: effect of a new gastrokinetic agent (cisapride).
Symptoms suggesting gastroparesis in patients without gastric outlet obstruction are very common but their relation to an objective delay of gastric emptying has been poorly investigated. A dual isotopic technique was used to evaluate patients with non-obstructive dyspepsia (idiopathic and secondary) (part 1) and to assess the effects of a new gastrokinetic agent: cisapride, on gastric emptying in such patients (part 2). Sixty patients with postprandial dyspeptic symptoms (vomiting, nausea, gastric bloating or full feeling) and without lesions at upper endoscopy were studied. They were distributed into three groups: idiopathic dyspepsia (n = 31), postvagotomy dyspepsia (n = 16) and dyspepsia secondary to medical disorders (n = 13). All patients ingested the same ordinary meal; 99mTc sulphur colloid tagged egg white was the solid phase marker and 111In chloride was the liquid phase marker. In part 1, evaluation of gastric emptying in the first 50 patients shows a delay of gastric emptying rate of solids and liquids as compared with controls. Striking differences separate the three groups of patients, however, percentages of delayed gastric emptying rate of solids and or liquids averaged 90% in postvagotomy or secondary dyspepsia groups whereas it was 44% in idiopathic dyspepsia group. Moreover, liquid emptying rate was often the only one impaired in idiopathic dyspepsia, and in 12 of the 27 patients of this group the faster emptying rate of liquids as compared with that of solids (always found in normal subjects), could not be evidenced. In part 2, 10 patients entered a double blind cross over study of cisapride (8 mg intravenously). A significant increase of solid (p<0.01) and liquid (p<0.05) emptying rates was found in patients with initial gastric emptying delay. This study emphasises the importance of an objective evaluation of gastric emptying in the presence of symptoms of gastric stasis and suggests that specific local acting therapy may be useful in patients with identified abnormal gastric emptying.

Effect of laparoscopic cholecystectomy on gastric emptying and dyspepsia.
Laparoscopic cholecystectomy has become the gold standard for treatment of symptomatic gallstone disease. Nonresolution of dyspepsia postoperatively is of major concern nowadays. The present study was conducted to study the effect of laparoscopic cholecystectomy on gastric emptying in symptomatic gallstone disease using (99m)Tc sulfur colloid scintigraphy. This pilot study sought to obtain preliminary data and to establish a base for further detailed study.. A total of 25 patients with a diagnosis of symptomatic gallstone disease scheduled for laparoscopic cholecystectomy were included in the study. All patients underwent gastric scintigraphic emptying study preoperatively and 2 weeks after laparoscopic cholecystectomy. Laparoscopic cholecystectomy was done as a day care procedure.. Mean ± standard deviation preoperative gastric percentage clearance was 51.36 ± 12.67%. Preoperative gastric emptying half-time was 62.72 ± 21.59 min. Forty percent of patients experienced dyspeptic symptoms before surgery. Twenty-four percent of patients had dyspeptic symptoms during postoperative follow-up at 2 weeks. Postoperative percentage gastric clearance was 49.92 ± 13.17%. Postoperative gastric emptying half-time was 64.12 ± 19.13 min. Statistical analysis revealed no significant effect of laparoscopic cholecystectomy on gastric emptying parameters.. Laparoscopic cholecystectomy does not alter gastric emptying or stomach percentage clearance in gallstone patients who have preoperative delayed gastric emptying on scintigraphy. Laparoscopic cholecystectomy has no effect on gastric emptying in symptomatic gallstone patients.

Electrogastrography in pediatric functional dyspepsia: relationship to gastric emptying and symptom severity.
The aims of this study were to determine the electrogastrographic patterns in children with functional dyspepsia and to investigate the correlations among electrogastrogram (EGG), gastric emptying (GE), and pain severity.. We studied 30 children (19 F; mean age 11.4 years) with functional dyspepsia. Electrogastrography was performed for 30 minutes fasting and for 1 hour during a GE test after ingestion of an isotope-labeled solid meal. The percent emptying was measured every 10 minutes for 1 hour after the meal. The dominant frequency of the EGG, the change in the postprandial peak power (deltaP), and percent dysrhythmia during each recording session were calculated. Specific symptoms were graded from 0 (none) to 4 (severe) by the patient.. Of 30 patients, 14 (47%) had slow GE, and 15 (50%) had abnormal EGG (dysrhythmia > or = 30% or deltaP < 0). GE was slow in 73% of patients with an abnormal EGG but was slow in only 20% of patients with normal EGG (P = 0.009). GE was negatively correlated with fasting bradygastria (r = -0.383, P = 0.04). Abdominal pain was the most severe dyspeptic symptom, both during fasting and after the meal. Patients with an abnormal EGG had an increased mean pain severity score (3.5 +/- 0.2 vs. 2.5 +/- 0.2, P = 0.002).. Sixty percent of functional dyspepsia subjects had either slow GE or abnormal EGG. Patients with abnormal EGG were more likely to have slow GE. EGG abnormalities were associated with more severe postprandial pain and should be considered a possible mechanism for dyspeptic symptoms.

Gastric electric activity assessed by electrogastrography and gastric emptying scintigraphy in adolescents with eating disorders.
Patients with eating disorders can refer to a variety of gastrointestinal symptoms, sometimes to justify reduced food intake and vomiting. The authors investigated whether adolescent patients with eating disorders and dyspeptic symptoms have altered gastric electric activity and abnormal gastric emptying as assessed respectively by electrogastrography and scintigraphy.. Twenty-eight patients (18 with anorexia and 10 with bulimia) and 16 healthy volunteers underwent electrogastrography; 20 of the 28 patients (14 with anorexia and 6 with bulimia) underwent gastric emptying scintigraphy. Electrogastrography with bipolar recording lasted 1 hour, 30 minutes before and after a standard meal. Before gastric emptying scintigraphy, patients fasted overnight; during testing, they ingested a solid meal labeled with technetium-99m sulfur colloid. The ratio of fasting to postprandial electrogastrographic variables was evaluated using the Wilcoxon matched-pair test. The Mann- Whitney test was used to compare absolute values for electrogastrographic data in each group. The Student paired t test was used to compare scintigraphic results expressed as percentage of gastric emptying at 60 minutes and as the gastric emptying time (T(1/2)).. Patients with bulimia significantly differed from those with anorexia and control subjects regarding the amount of normal gastric electric activity and bradygastria, and from patients with anorexia only regarding tachygastria. These electrogastrographic variables did not differ significantly between patients with anorexia and control subjects. Gastric emptying time (T(1/2)) was significantly longer in patients with bulimia than in those with anorexia.. Adolescent patients with bulimia who complain of dyspeptic symptoms have documentable abnormalities of gastric electric activity and emptying, whereas their counterparts with anorexia, probably owing to their shorter disease duration, do not.

Electrogastrography and gastric emptying scintigraphy are complementary for assessment of dyspepsia.
We have tried to correlate abnormalities in electrogastrography (EGG) and gastric emptying (GE) with symptom severity in patients with functional dyspepsia. Seventy-two patients with functional dyspepsia underwent EGG, GE, and symptom severity quantitation. EGGs were assessed for dominant frequency (DF), percentage of time of DF in the 2 to 4 cpm range, and postprandial-fasting DF power ratio. Solid-phase GE scintigraphy was assessed for 2-hour percentage retention. Symptoms of upper abdominal discomfort, early satiety, postprandial abdominal distension, nausea, vomiting, and anorexia were graded as none (0), mild (1), moderate (2), and severe (3); the sum represented a total symptom score. The EGG was abnormal in 11 of 22 (50%) patients with delayed GE compared with 11 of 50 (22%) with normal GE (p < 0.025). The total symptom scores were higher in patients with both delayed GE and abnormal EGG compared with patients with normal GE and EGG, normal GE and abnormal EGG, and delayed GE and normal EGG. We conclude that EGG abnormalities are more common in dyspeptic patients with delayed GE. Patients with both delayed GE and abnormal EGG have more severe symptoms. Our results suggest that EGG and GE complement each other in correlating symptoms to gastric dysmotility.

Physiological effect of cholecystokinin on gastric emptying of liquid in functional dyspepsia.
Early satiety and postprandial epigastric fullness are common symptoms in functional dyspepsia. Cholecystokinin (CCK), a mediator of satiety in humans, may be responsible for these symptoms through an increased effect on delaying gastric emptying.. In five normal subjects and in five patients, gastric emptying of inert liquid mixed with technetium (Tc99m) was studied during i.v. perfusion of normal saline and of physiological concentrations of CCK octapeptide.. Administration of CCK significantly delayed emptying of inert liquid in patients and in normal subjects, and the effect was of similar magnitude in the two groups: residual gastric volumes at 90 min increased from 9.9 +/- 6.1 to 32.1 +/- 6.2% (p < 0.025) in controls and from 9.8 +/- 4.4 to 32.2 +/- 4.7% (p < 0.005) in patients during saline infusion in comparison with CCK infusion; also, prolongation of half emptying time was not different between the two groups (19.4 +/- 1.9 min to 39.4 +/- 15.2 min in controls and 19.5 +/- 3.0 min to 31.4 +/- 7.9 min in patients).. We conclude that CCK at physiological concentrations acts similarly in normal subjects and in patients with functional dyspepsia; this suggests that, if this hormone is normally released after a meal, a peripheral action of CCK through delayed gastric emptying is not responsible for increased postprandial satiety in functional dyspepsia.

[Effect of clebopride on gastric emptying studied using a physiologic meal marked with Tc 99m colloid in subjects with non-ulcer dyspepsia].
The authors studied the action of clebopride on gastric emptying in subjects with non-ulcer dyspepsia by using radioactive isotopes. Eighteen subjects complaining of dyspeptic symptoms were studied in whom the tests undertaken had not shown organic lesions of the digestive tract. Tests with radioactive isotopes were performed before and after administration of clebopride (0.5 mg, three times daily for 15 days). In all patients gastric emptying time was normalized and gastric peristalsis became regular. In addition, in 85% of the patients, symptoms disappeared or were markedly reduced. Side effects requiring withdrawal of the drug were not observed. The above study, therefore, showed clebopride to be a useful drug for the treatment of non-ulcer dyspepsia, thus confirming data found in the literature.

Lack of association between gastric emptying of solids and symptoms in nonulcer dyspepsia.
Gastric motor dysfunction and concomitant gastric stasis have been implicated in the pathogenesis of nonulcer dyspepsia, but a cause-and-effect relationship is not established. Essential dyspepsia refers to a subgroup of nonulcer dyspepsia patients who have no evidence of irritable bowel syndrome, gastroesophageal reflux, or pancreaticobiliary disease. In 32 patients with essential dyspepsia, and 32 randomly selected dyspepsia-free community controls of similar age and sex, we measured gastric emptying of solids using Tc99m-Sulphur Colloid in a fried egg sandwich. Subjects with neuromuscular or other diseases that may alter gastric emptying were excluded. Symptoms were assessed by a standard questionnaire. Data processing was carried out "blinded" to the subjects' clinical status. Female patients took significantly longer to empty half the initial stomach activity (mean 90 min) than female controls (mean, 73 min; p = 0.02). The rate of emptying at 25 min was also significantly less in female patients than in controls. Female and male controls, and male patients, had similar emptying times. Delayed emptying was not associated with the occurrence of postprandial pain, belching, or nausea; there was a trend for the half-time rate of emptying to be greater in patients with abdominal distention. While gastric emptying of solids is slightly delayed in females with essential dyspepsia as a group, this may not explain their symptoms.

[Gastric emptying of solids in patients with nonorganic dyspepsia].
The purpose of this work was to evaluate gastric emptying of a solid meal in 20 patients with functional dyspepsia and in 20 healthy controls. Gastric emptying time (T 1/2 = 188.45 +/- 93.79; p less than 0.001 - E.I. = 0.43 +/- 0.16; p less than 0.001) was significantly delayed in patients with functional dyspepsia compared with controls. The conclusion is drawn that either antral motor activity or antral-pyloric-duodenal motor activity is impaired in such patients.

Effect of cisapride on gastric emptying in dyspeptic patients.
The effect of the new gastrokinetic agent cisapride on gastric emptying was evaluated in 17 dyspeptic patients using the dual radionuclide technique. Eight patients with idiopathic dyspepsia and nine postsurgical dyspeptic patients were studied and compared to a control group. Gastric emptying of solids and liquids was determined after ingestion of a standardized meal using 99mTc-sulfur colloid scrambled eggs as the solid phase and [111In]DTPA-labeled water as the liquid phase. Following a basal study and on a separate occasion, each patient received an intravenous bolus of 10 mg of cisapride after ingestion of the test meal; 10 of the patients were restudied after a two-week period of chronic oral administration of the drug (10 mg four times a day). Baseline gastric emptying of solids was significantly delayed in idiopathic and postsurgical patients; liquid emptying was only delayed in the postsurgical group. Intravenous and oral administration of cisapride significantly shortened gastric emptying in both groups. In all but one patient, the clinical improvement was confirmed by the test. Cisapride appears to be a good alternative to metoclopramide and domperiodone in the treatment of dyspeptic patients. The dual radionuclide technique appears to be a useful physiologic tool for evaluating and predicting the efficacy of a gastric prokinetic therapy in man.
