Association of fructose consumption with prevalence of functional gastrointestinal disorders manifestations: results from Hellenic National Nutrition and Health Survey (HNNHS). Br J Nutr 2023; 130:1961-1972. [PMID: 37197939 PMCID: PMC10630147 DOI: 10.1017/s0007114523001198] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/22/2022] [Revised: 05/02/2023] [Accepted: 05/09/2023] [Indexed: 05/19/2023]
Abstract
The study aimed to assess the total prevalence of functional gastrointestinal disorders (FGID), and separately, irritable bowel syndrome (IBS) among adults and to determine their potential association with fructose consumption. Data from the Hellenic National Nutrition and Health Survey were included (3798 adults; 58·9 % females). Information regarding FGID symptomatology was assessed using self-reported physician diagnosis questionnaires the reliability of which were screened using the ROME III, in a sample of the population. Fructose intake was estimated from 24 h recalls, and the MedDiet score was used to assess adherence to the Mediterranean diet. The prevalence of FGID symptomatology was 20·2 %, while 8·2 % had IBS (representing 40·2 % of total FGID). The likelihood of FGID was 28 % higher (95 %CI: 1·03-1·6) and of IBS 49 % (95 %CI: 1·08-2·05) in individuals with higher fructose intake than with lower intake (3rd tertile compared with 1st). When area of residence was accounted for, individuals residing in the Greek islands had a significantly lower probability of FGID and IBS compared with those residing in Mainland and the main Metropolitan areas, with Islanders also achieving a higher MedDiet score and lower added sugar intake, comparatively to inhabitants of the main metropolitan areas. FGID and IBS symptomatology was most prominent among individuals with higher fructose consumption, and this was most conspicuous in areas with a lower Mediterranean diet adherence, suggesting that the dietary source of fructose rather than total fructose should be examined in relation to FGID.

Abstract
Gastric Cancer epidemics have changed over recent decades, declining in incidence, shifting from distal to proximal location, transforming from intestinal to diffuse histology. Novel chemotherapeutic agents combined with modern surgical operations hardly changed overall disease related survival. This may be attributed to a substantial inherent geographical variation of disease genetics, but also to a failure to standardize and implement treatment protocols in clinical practice. To overcome these drawbacks in Greece and Cyprus, a Gastric Cancer Study Group under the auspices of the Hellenic Society of Medical Oncology (HeSMO) and Gastrointestinal Cancer Study Group (GIC-SG) merged their efforts to produce a consensus considering ethnic parameters of healthcare system and the international proposals as well. Utilizing structured meetings of experts, a consensus was reached. To achieve further consensus, statements were subjected to the Delphi methodology by invited multidisciplinary national and international experts. Sentences were considered of high or low consensus if they were voted by ≥ 80%, or < 80%, respectively; those obtaining a low consensus level after both voting rounds were rejected. Forty-five statements were developed and voted by 71 experts. The median rate of abstention per statement was 9.9% (range: 0-53.5%). At the end of the process, one statement was rejected, another revised, and all the remaining achieved a high consensus. Forty-four recommendations covering all aspects of the management of gastric cancer and concise treatment algorithms are proposed by the Hellenic and Cypriot Gastric Cancer Study Group. The importance of centralization, care by a multidisciplinary team, adherence to guidelines, and individualization are emphasized.

Abstract
BACKGROUND Invasive measurement of the hepatic venous pressure gradient (HVPG) is regarded as the gold standard for risk stratification and the evaluation of pharmaceutical agents in patients with portal hypertension. AIM To review the techniques for endoscopic and imaging-based assessment of portal haemodynamics, with particular emphasis on trials where the results were compared with HVPG or direct portal pressure measurement. METHODS Systematic search of the MEDLINE electronic database with keywords: portal hypertension, variceal bleeding, variceal pressure, endoscopic ultrasound, Doppler ultrasonography, magnetic resonance angiography, CT angiography, hepatic venous pressure gradient. RESULTS Computed tomography angiography and endoscopic ultrasound (EUS) have been both employed for the diagnosis of complications of portal hypertension and for the evaluation of the efficacy of endoscopic therapy. Colour Doppler ultrasonography and magnetic resonance angiography has given discrepant results. Endoscopic variceal pressure measurements either alone or combined with simultaneous EUS, correlate well with HVPG and risk of variceal bleeding and have a low interobserver variability. CONCLUSIONS Endoscopic and imaging-based measurements of portal haemodynamics provide an alternate means for the assessment of complications of portal hypertension. Further studies are required to validate their use in risk stratification and the evaluation of drug therapies in patients with portal hypertension.

Abstract
BACKGROUND AND AIMS The relationship between hiatus hernia and reflux esophagitis is well established. However, there are conflicting reports regarding its effect on the development of nonerosive reflux disease (NERD). Our aim was to investigate the prevalence and axial length of hiatus hernia in patients with NERD, compared with patients with reflux esophagitis, Barrett esophagus, and controls. METHODS Axial hernia length of the diaphragmatic hiatus was measured prospectively at endoscopy in controls and patients with typical reflux symptoms occurring at least weekly during the last month relieved by antacids. RESULTS A final diagnosis of hiatus hernia was established in 21.2% of 249 controls, 60.4% of 346 patients with NERD, 78.1% of 251 patients with reflux esophagitis, and 88.2% of 17 patients with Barrett esophagus. Patients aged >59 years were most likely to have a hiatus hernia. There was an increased prevalence in patients with NERD as compared with controls (P<0.0001), and decreased prevalence as compared with those with reflux esophagitis and Barrett esophagus (P<0.0001 and 0.02, respectively). Axial length of hiatus hernia >3 cm was found more frequently in patients with reflux esophagitis and Barrett esophagus as compared with patients with NERD (P<0.0001 and 0.0052, respectively). There was no statistical significant difference between controls and patients with NERD regarding the prevalence of hiatus hernia >3 cm (P=0.0904). CONCLUSIONS A small (<3 cm) hiatus hernia may contribute to the development of NERD, whereas an axial length >3 cm is associated with a more severe disease.

Abstract
BACKGROUND In sphincter of Oddi dysfunction (SOD), sphincter of Oddi manometry (SOM) predicts the response to sphincterotomy, but is invasive and associated with complications. AIM To evaluate the role of secretin-stimulated magnetic resonance cholangiopancreatography (ss-MRCP) in predicting the results of SOM in patients with suspected type II or III SOD. METHODS MRCP was performed at baseline and at 1, 3, 5 and 7 min after intravenous secretin. SOD was diagnosed when the mean basal sphincter pressure at SOM was >40 mm Hg. Long-term outcome after SOM, with or without endoscopic sphincterotomy, was assessed using an 11-point (0-10) Likert scale. RESULTS Of 47 patients (male/female 9/38; mean age 46 years; range 27-69 years) referred for SOM, 27 (57%) had SOD and underwent biliary and/or pancreatic sphincterotomy. ss-MRCP was abnormal in 10/16 (63%) type II and 0/11 type III SOD cases. The diagnostic accuracy of ss-MRCP for SOD types II and III was 73% and 46%, respectively. During a mean follow-up of 31.6 (range 17-44) months, patients with normal SOM and SOD type II experienced a significant reduction in symptoms (mean Likert score 8 vs 4; p = 0.03, and 9 vs 1.6; p = 0.0002, respectively), whereas in patients with SOD type III, there was no improvement in pain scores. All patients with SOD and an abnormal ss-MRCP (n = 12) reported long-term symptom improvement (mean Likert score 9.2 v 1.2, p<0.001). CONCLUSIONS ss-MRCP is insensitive in predicting abnormal manometry in patients with suspected type III SOD, but is useful in selecting patients with suspected SOD II who are most likely to benefit from endotherapy.

Abstract
BACKGROUND Distal esophageal (Schatzki's) ring is a frequent cause of dysphagia. Bougienage is generally effective but relapses are common. The aim of this study was to evaluate the safety and long-term efficacy of single-session graded esophageal dilation with Savary dilators, without fluoroscopic guidance, in outpatients who presented with Schatzki's ring. METHODS The study was performed on 44 consecutive patients with symptomatic Schatzki's ring, detected endoscopically and/or radiologically. Graded esophageal dilation was performed as an outpatient procedure in a single session with Savary dilators, without fluoroscopic guidance. After appropriate assessment with esophageal manometry and 24 h ambulatory pHmetry, patients with documented gastroesophageal reflux disease (GERD) were treated with omeprazole continuously. All results, including clinical follow up and technical aspects of bougienage, were recorded prospectively. The necessity for re-dilation after documentation of the ring with endoscopy and/or radiology was considered as a relapse of the ring. RESULTS In four (9%) patients a second session was necessary to ensure complete symptom relief. Two (4.5%) patients developed post-dilation bacteremia and were managed with antibiotics as outpatients. Patients with (n = 14) or without (n = 30) GERD were comparable with respect to sex, age, body mass index, smoke and ethanol consumption, diameter of the esophageal lumen at the level of the ring, resting lower esophageal sphincter pressure, duration of dysphagia, need for taking antacids during the follow-up period, and duration of follow-up. There was no recurrence of the ring in patients with GERD during a mean follow-up period of 43.8 +/- 9.3 months (range 27-62 months); however, in patients without GERD, during a mean follow-up period of 40.6 +/- 12.2 months (range 10-58 months), 32% of patients relapsed after a mean 19.9 +/- 10.6 months (P = 0.04). CONCLUSIONS Single-session graded esophageal dilation with large caliber Savary dilators without fluoroscopic guidance can be safely used for the symptomatic relief in patients with lower esophageal (Schatzki's) rings. GERD should be treated if present in order to prevent a symptomatic recurrence of the ring.

Abstract
The high prevalence of gastroesophageal reflux disease (GERD) in Western societies has accelerated the need for new modalities of treatment. Currently, medical and surgical therapies are widely accepted among patients and physicians. The minimally invasive treatment revolution, however, has stimulated several new endoscopic techniques for GERD. Up to now, the data is limited and further studies are necessary to compare the advantages and disadvantages of the various endoscopic techniques to medical and laparoscopic management of GERD. This systematic review reports the efficacy and durability of various endoscopic therapies for GERD whilst the potential for widespread use of these techniques is also discussed. Despite the limited number of studies and remarkable differences between various trials, strict criteria were used for the pooled data presented and an effort was made to avoid bias by including only studies that used off-antisecretory medication scoring as baseline and intent to treat.

Abstract
Patients with refractory heartburn to proton pump inhibitors (PPIs) represent a distinctive group which is difficult to manage. In a systematic review of the relative literature we found that approximately 20% of patients with erosive esophagitis and 15-25% of patients with normal endoscopy and abnormal 24-hour esophageal pH monitoring continue to report heartburn despite treatment with standard dose PPIs. Furthermore, approximately 30-40% of patients with normal endoscopy and 24-hour pH studies and 15-20% of patients with Barrett's esophagus have refractory heartburn to double dose PPIs. In such cases, compliance to therapy, duodeno-gastroesophageal reflux, gastro-esophageal motility disorders and eradication of Helicobacter pylori infection may contribute to symptoms. Based on the available evidence, we suggested an algorithm for the evaluation and management of these patients.

Abstract
Until recently, endoscopic retrograde cholangiopancreatography (ERCP) has been considered the gold standard for the diagnosis of and therapy in patients with suspected choledocholithiasis. However, the non-negligible complication rate of diagnostic and therapeutic ERCP has led investigators to identify different noninvasive diagnostic modalities. Endoscopic ultrasonography has been proved to be of great sensitivity (up to 97%) in the diagnosis of even tiny stones that can be easily masked by contrast medium during ERCP, without any procedure-related complications and with a negative predictive value reaching 100%, meaning that it can accurately and safely identify patients with choledocholithiasis, thereby avoiding inappropriate instrumental exploration of the common bile duct.

Abstract
It is well established that only a minority of patients with Helicobacter pylori infection develop severe inflammation leading to peptic ulcer or gastric cancer. Recent evidence suggests that the virulence factors of the organism do not seem crucial in the progression of inflammation towards a more severe disease. It seems probable that other host derived and environmental factors are more significant in determining clinical outcome but additional studies are needed to clarify the underlying mechanisms involved in the pathogenesis of infection.

Abstract
BACKGROUND Sphincter of Oddi dysfunction is a benign, functional gastrointestinal disorder for which invasive endoscopic therapy with potential complications is often recommended. AIMS To review the available evidence regarding the diagnostic accuracy of non-invasive methods that have been used to establish the diagnosis and to estimate the long-term outcome after endoscopic sphincterotomy. METHODS A systematic review of English language articles and abstracts containing relevant terms was performed. RESULTS Non-invasive diagnostic methods are limited by their low sensitivity and specificity, especially in patients with Type III sphincter of Oddi dysfunction. Secretin-stimulated magnetic resonance cholangiopancreatography appears to be useful in excluding other potential causes of symptoms, and morphine-provocated hepatobiliary scintigraphy also warrants further study. Approximately 85%, 69% and 37%, of patients with biliary Types I, II and III sphincter of Oddi dysfunction, respectively, experience sustained benefit after endoscopic sphincterotomy. In pancreatic sphincter of Oddi dysfunction, approximately 75% of patients report symptomatic improvement after pancreatic sphincterotomy, but the studies have been non-controlled and heterogeneous. CONCLUSIONS Patients with suspected sphincter of Oddi dysfunction, particularly those with biliary Type III, should be carefully evaluated before considering sphincter of Oddi manometry and endoscopic sphincterotomy. Further controlled trials are needed to justify the invasive management of patients with biliary Type III and pancreatic sphincter of Oddi dysfunction.

Abstract
Eosinophilic esophagitis is a condition that is being increasingly recognized in adults. The main presenting symptoms are dysphagia (93 %), food impaction (62 %), and heartburn (24 %). A history of allergy is obtained in 52 % of patients and peripheral eosinophilia is found in 31 % of patients with this condition. Esophageal manometric studies have provided evidence of a nonspecific motility disorder in 40 % of patients. Endoscopic findings include mucosal fragility or edema (59 %), solitary or multiple concentric rings (49 %), strictures (40 %), whitish pinpoint exudates or papules (16 %), and a small-caliber esophagus (5 %); 9 % of patients present with a normal endoscopy. Esophageal dilation in adults with eosinophilic esophagitis has limited efficacy and is associated with an increased complication rate compared with dilation in patients with benign strictures. The administration of inhaled or systemic corticosteroids results in symptomatic improvement in nearly 95 % of patients. A trial with corticosteroids before bougienage may reduce active inflammation and therefore the complication rate of the procedure.

Abstract
Endoscopic ultrasonography has recently emerged as an accurate, non-invasive and reproducible alternative means of providing data for patients with portal hypertension. It is well established that endoscopic ultrasonography is more sensitive than endoscopy in the diagnosis of gastric varices. Dilated venous abnormalities outside the gastrooesophageal lumen, which cannot be diagnosed by endoscopy, are readily visible with endoscopic ultrasonography or miniature probes. Endoscopic ultrasonography is also useful to predict the risk of variceal recurrence and thus the risk of rebleeding after endotherapy which cannot be reliably predicted using endoscopy alone. The introduction of echo endoscopes equipped with Doppler facilities has allowed the sonographic visualisation of the vessels and the evaluation of vascular blood flow along with possible morphologic and haemodynamic changes after endoscopic or pharmacological therapy. However, despite its theoretical advantages, relative evidence suggests that in the clinical setting of portal hypertension, endoscopic ultrasonography remains an investigational tool with limited clinical applications.

Abstract
BACKGROUND AND AIMS Conservative therapy for patients with acute colonic pseudo obstruction (Ogilvie's syndrome) may be successful initially but relapses are common. The aim of the present study was to evaluate the effect of polyethylene glycol (PEG) electrolyte balanced solution on the relapse rate of the syndrome after initial resolution with neostigmine or endoscopic decompression. PATIENTS AND METHODS The study was performed on 30 consecutive patients who presented with abdominal distension and radiographic evidence of colonic dilation, with a caecal diameter > or = 10 cm, that resolved conservatively. Patients then were randomised to receive daily 29.5 g of PEG (n = 15) or similar placebo (n = 15). Patients were monitored daily for a seven day period for stool and flatus evacuations, and colonic diameter on abdominal radiographs. Administration of the test solutions and assessment of patient symptoms and x rays were performed in a blinded fashion. A caecal diameter > or = 8 cm with a concomitant > or =10% increase after initial successful therapeutic intervention was considered as a relapse and these patients, after a second therapeutic intervention, were eligible to receive open label PEG. RESULTS Twenty five patients received neostigmine as the initial therapeutic intervention which resulted in resolution of colonic dilation in 88% of cases. Eight patients had successful endoscopic decompression. Five (33.3%) patients in the placebo group had recurrent caecal dilation compared with none in the PEG group (p = 0.04). Therapy with PEG resulted in a significant increase in stool and flatus evacuations (p = 0.001 and 0.032, respectively) as well as in a significant decrease in the diameter of caecum, ascending and transverse colon, and abdominal circumference (p = 0.017, 0.018, 0.014, and 0.008, respectively). CONCLUSIONS Administration of PEG in patients with Ogilvie's syndrome after initial resolution of colonic dilation may increase the sustained response rate after initial therapeutic intervention.

Abstract
BACKGROUND AND AIMS Endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) has a diagnostic accuracy of 70-90%, depending on the site under evaluation. In order to improve EUS-guided tissue sampling a novel 19-gauge trucut-type needle has been designed to obtain core biopsies during EUS. We prospectively evaluated the safety and accuracy of EUS-FNA alone versus combined EUS-FNA and trucut needle biopsy (TNB) in patients referred to our Unit over a 3-year period. PATIENTS AND METHODS A total of 159 patients underwent EUS-FNA alone (lesions<2 cm) or the combination of both sampling modalities (lesions>or=2 cm). The adequacy of sampling, sensitivity, specificity and overall accuracies of EUS-FNA or EUS-TNB alone and combined EUS-FNA/TNB were determined. RESULTS Adequate samples were obtained by EUS-FNA, EUS-TNB and EUS-FNA/TNB in 91%, 88% and 97% of patients, respectively. From the pancreas (n=83), adequate samples were obtained by FNA in 94% and by TNB in 81%, compared with 87% and 92% from non-pancreatic sites (n=76), respectively. The combination of both techniques resulted in more adequate samples from non-pancreatic cases than EUS-FNA alone (P=0.044). The specificity was 100%. Overall accuracy for EUS-FNA alone was 77%, for EUS-TNB alone 73% and for EUS-FNA/TNB 91% (P=0.008). For pancreatic sampling, the accuracy of EUS-FNA alone was 77%, for EUS-TNB alone 56% and for EUS-FNA/TNB 83%. For non-pancreatic sampling, the accuracy for EUS-FNA alone was 78%, for EUS-TNB alone 83% and for EUS-FNA/TNB 95% (P=0.006). The complication rate was 0.6%. CONCLUSIONS Combined EUS-FNA/TNB for lesions>or=2 cm improves adequacy of sampling and diagnostic accuracy compared with either technique alone and is safe.

Abstract
Peptic ulcer bleeding remains a common medical emergency and despite recent advances in management is still associated with high mortality. Endoscopic treatment remains the cornerstone for the effective management of high-risk patients. Recent evidence suggests that potent antisecretory drugs that inhibit gastric acid secretion, such as proton pump inhibitors, may be of help alone or in combination with endotherapy in the management of peptic ulcer bleeding. Somatostatin appears to offer a distinct advantage over antisecretory drugs, as it inhibits both acid and pepsin secretion and combines these effects with a reduction in gastroduodenal mucosal blood flow which seems to be important in the pathophysiology of peptic ulcer bleeding. Additionally, the inhibition of pepsin secretion might induce a decreased proteolytic activity preventing the dissolution of freshly formed clots at the site of bleeding. Despite its theoretical advantages, there has been very little evidence in the recent past in setting of randomised, controlled, clinical trials. In reviewing the available data, we found that the efficacy of somatostatin and its analogue octreotide are different in the control of peptic ulcer bleeding and this might be due to the different distribution of its receptors through the GI tract. Further studies are needed to define the exact role, if any, of somatostatin and its analogues, in high-risk patients with peptic ulcer bleeding and this might be a rather interesting area for future research.

Abstract
BACKGROUND/AIMS Eosinophilic esophagitis (EE) is an increasingly recognized condition both in children and adults. The aim of the present study was to review the available evidence regarding EE in adults. METHODS PubMed, MEDLINE and medical textbooks were searched in May-June 2005 for English-language articles published between January 1978 and June 2005 containing relevant terms. The abstracts of two major conferences from 2000 to June 2005 were also reviewed. The presence of more than 15 eosinophils per high power field on esophageal biopsies was required to establish the diagnosis. RESULTS Twenty-four studies with 325 patients (male/female ratio: 3/1) were found that met the review criteria. Presenting symptoms included dysphagia (93%), food impaction (62%) and heartburn (23.6%). An allergic history and peripheral eosinophilia was noted in 51.6 and 30.8% of patients, respectively. Esophageal manometry presented evidence of a motility disorder in 40% of cases. Endoscopic findings included mucosal fragility/oedema, rings, strictures, whitish pinpoint exudates and small-calibre esophagus in 59.3, 49.2, 39.7, 15.7 and 5.3% of cases, respectively, whereas 8.8% of patients had a normal endoscopy. Bougienage was performed in 64 patients, with limited efficacy and an increased complication rate. The administration of corticosteroids resulted in symptomatic improvement in more than 95% of cases. CONCLUSIONS An allergic history and peripheral eosinophilia is less common in adults than among children with EE. An esophageal motility disorder should be a novel indication for biopsies in adults with long-lasting dysphagia. A trial with corticosteroids before bougienage may reduce active inflammation and the complication rate.

Abstract
OBJECTIVES Distal esophageal (Schatzki's) rings are a frequent cause of dysphagia. Bougienage is generally effective, but relapses are common. The aim of this study was to evaluate the effect of long-term antisecretory therapy on the relapse rate of lower esophageal rings after successful bougienage with Savary dilators. PATIENTS AND METHODS The study was performed on 44 consecutive patients with symptomatic Schatzki's rings, detected endoscopically, and/or radiologically. Graded esophageal dilation was performed as an outpatient procedure in a single session. After appropriate assessment with esophageal manometry and 24-h ambulatory esophageal pH monitoring, patients with documented GERD (n = 14) were treated with long-term omeprazole therapy. The remaining patients were blindly randomized to receive maintenance treatment with either omeprazole (group A-15 patients) or placebo (group B-15 patients). The necessity for redilation after documentation of the ring with endoscopy and/or radiology was considered as a relapse of the ring. The relapse rate was evaluated in all groups. RESULTS All bougienages were performed without significant side effects. Eight patients (8 of 44, 18.2%) had one or more relapses after a mean (SD) of 19.0 (10.1) months. Patients with (n = 14) or without (n = 30) GERD were comparable with respect to sex, age, body mass index, cigarette and alcohol consumption, diameter of the esophageal lumen at the level of the ring, resting lower esophageal sphincter pressure, duration of dysphagia, need for taking antacids during the follow-up period, and duration of follow-up. There were no recurrences of Schatzki's ring in the group of patients with documented GERD (follow-up [mean +/- SD]: 43.8 +/- 9.3 months, range: 27-62). In group A (follow-up [mean +/- SD]: 37.1 +/- 17.1 months, range: 11-66), one patient relapsed after 13 months, while in group B (follow-up [mean +/- SD]: 34.3 +/- 14.6 months, range: 10-58), seven patients relapsed after a mean (SD) of 19.9 (10.6) months. The actuarial probability of relapse was higher in patients without therapy (group B) (p= 0.008). CONCLUSIONS Our data support the hypothesis that, in patients with symptomatic Schatzki's rings, acid suppressive maintenance therapy after bougienage may prevent relapse of the ring.

Abstract
Intramural duodenal hematoma is a rare complication of endoscopic biopsy. It is usually seen in children with growth failure and in patients with bleeding disorders or who are anticoagulated. It is frequently associated with acute pancreatitis. We present a case of an adult patient with Noonan's syndrome who developed postbiopsy intraduodenal hematoma. Abdominal ultrasound and computed tomography scan established the diagnosis. Conservative treatment was successful. According to a brief review of the literature, patients with Noonan's syndrome may develop hematoma after sampling of the duodenum because they present all the main predisposing factors. Additionally, pulmonic valve stenosis may be another predisposing factor, but this may warrant further investigation.

Abstract
BACKGROUND The aim of the present study was to evaluate the effect of gallstone disease (GD) and laparoscopic cholecystectomy on gastric electrical activity of slow waves, which was recorded via transcutaneous electrogastrography (EGG). METHODS Twenty-one consecutive patients (M/F: 12/9, 52.7 +/- 15 years old) with GD and no previous history of abdominal operations or known disease affecting gastrointestinal motility were studied. The EGG was performed for 30 min prior to and 90 min after a standard meal, during a 4-6 month period prior to and after laparoscopic cholecystectomy. The percentile proportion of the three spectra of gastric slow waves frequency was studied, defined as follows: bradygastria, 1-2.1 cycles per min (c.p.m.); normogastria, 2.2-3.9 c.p.m.; and tachygastria, 4-9 c.p.m. The findings were compared to those of nine healthy subjects (M/F: 5/4, 49.5 +/- 14.8 years old). RESULTS No statistically significant difference was found in percentile distribution of bradygastria, normogastria and tachygastria, pre- or post-prandially, neither before or after laparoscopic cholecystectomy, nor between patients and controls. CONCLUSIONS Patients with GD do not exhibit differences in gastric electrical activity of slow waves in comparison to normal subjects and laparoscopic cholecystectomy does not alter gastric electrical activity. These findings suggest that cholelithiasis does not seem to cause dyspeptic symptoms due to gastric dysrythmias.
