A retrospective study of 200 endoscopies performed on 168 children (90 girls and 78 boys) aged 3 months to 18 years (median 6 years) is reported. All procedures were completed successfully in an adult endoscopy unit in a comprehensive health centre. Most children of less than 6 months and above 12 years of age needed no intravenous sedation. One child developed respiratory depression and was successfully resuscitated. Indications for endoscopy were: small intestinal biopsy, 78 (46%); recurrent abdominal pain, 40 (24%); acute epigastric pain, 13 (8%); persistent vomiting, 12 (7%); haemorrhage, 10 (6%); caustic substance ingestion, six (4%); and dysphagia, four (2%) children. Positive diagnoses were obtained in 123 (62%) procedures. Coeliac disease (26 cases) was the most common histological diagnosis, followed by gastritis (19 cases), oesophagitis (18 cases), duodenitis (16 cases), duodenal ulcer (11 cases), hiatus hernia (six cases), gastric ulcer (three cases) and oesophageal stricture (two cases). Where specialized paediatric endoscopy units are not feasible, e.g. in developing countries, endoscopic services for children can be safely provided by paediatric endoscopists as part of an adult endoscopy service, provided that suitable resuscitation equipment is available and the necessary modifications to meet the medical and psychological needs of children and their parents are taken into consideration.

In total 199 oesophago-gastro-duodenoscopies (OGD) were performed in 71 female and 71 male paediatric patients (three months-15 years, median 8 years 2 months). The endoscopy was performed in general anaesthesia in children less than five years old, and in an intravenous sedation in older patients. The indications for OGD were: recurrent abdominal pain and concomitant positive antibodies against Helicobacter pylori as a part of a scientific project, upper dyspepsia, upper gastrointestinal bleeding, failure to thrive, coeliac disease, suspicion of chronic inflammatory bowel disease and a percutaneous gastrostomy. Seventy-two OGD were carried out in general anaesthesia, 86 in intravenous sedation with midazolam and pethidine and 41 in intravenous midazolam sedation. Complications related to the sedation or to the endoscopy were not observed. Amnesia was reported in 94/95 children who were sedated intravenously with midazolam and pethidine or midazolam alone. Six endoscopies could not be carried out in intravenous sedation because of agitation. In the primary OGD endoscopy revealed a normal mucosa in 121/142 (85%), oesophagitis in four (3%), nodular mucosa in six (4%), gastritis in four (3%) and a duodenal ulcer in one (0.7%). Histology disclosed active or inactive chronic gastritis at the primary endoscopy in 35/69 (51%) of the children with recurrent abdominal pain and antibodies against H. pylori. In children with failure to thrive an avillous duodenal mucosa was seen in 3/32 (9%). A comparison between histological and stereomicroscopical evaluation of the duodenal biopsies revealed agreement in 41/47 (87%). We conclude that OGD is a safe and tolerable procedure in paediatric patients, in whom possible morphological changes are suspected. The indications for an OGD need further evaluation.

A four-year-old boy who had a long history of upper respiratory tract infections and growth retardation was admitted because of recurrent abdominal pain. During upper gastrointestinal series to search for a gastric or duodenal ulcer, the examiner noticed a minute amount of contrast medium within the trachea. Repeat esophagography on an angiographic table led to the correct diagnosis of a congenital H-type fistula. The patient did not have the classical symptoms of a history of choking and cyanosis after feeding during infancy or recurrent lower respiratory tract infections. The only finding consistent with a fistula was growth retardation, and the diagnosis was established incidentally during a work-up for abdominal pain.

Peptic ulcers in infants are rare. We report a 5-year-old boy who was admitted with recurrent bleeding from a huge duodenal ulcer. There were no concomitant disease and no preceding symptoms discovered. The only clinical symptom was bloody stool of light red color what led to diagnostic problems. Upper gastrointestinal bleeding was not considered initially. Short transit time through the gut may suggest a bleeding source within the lower intestine. Gastroscopy was performed delayed. Injection therapy of the ulcer once using fibrin sealant was followed by definite cessation of bleeding. Helicobacter pylori was not found. Hormone producing tumors could be excluded. There was a psycho-social situation of stress recognizable for the infant. The pathogenic mechanism of peptic ulceration due to psycho-social stress is unknown and somewhat doubtful at all. Peptic ulcer disease in infants and children should more often be considered when dealing with diffuse abdominal pain or with gastrointestinal bleeding.

A total of 1,456 patients were available for the All Patients Treated analysis of two large, randomized, double-blind, multicenter, controlled studies (Acid Suppression Trial: Ranitidine versus Omeprazole for NSAID-Associated Ulcer Treatment [ASTRONAUT] and Omeprazole versus Misoprostol for NSAID-Induced Ulcer Management [OMNIUM]). These studies examined the efficacies of omeprazole, 20 and 40 mg once daily (both studies), ranitidine, 150 mg twice daily (ASTRONAUT), and misoprostol, 200 microg four times daily (OMNIUM), for the healing of gastric ulcer, duodenal ulcer, or erosions, and the relief of dyspeptic symptoms. At entry, patients were receiving, and continued to receive, nonsteroidal anti-inflammatory drugs (NSAIDs), and had a gastric or duodenal ulcer, and/or >10 erosions in the stomach or duodenum at initial endoscopy. Patients were randomized to blinded treatment for 4/8 weeks until treatment success, which was defined as the healing of ulcer(s), <5 erosions at any site, and not more than mild dyspeptic symptoms. The proportions of patients reaching treatment success by 8 weeks were 77% with both doses of omeprazole, 63% with ranitidine, and 71% with misoprostol. In patients who initially had a gastric ulcer, more ulcers were healed at 8 weeks with omeprazole, 20 (83%) and 40 mg once daily (82%), than with ranitidine (64%) or misoprostol (74%). In patients who initially had a duodenal ulcer, 93% were healed at 8 weeks with omeprazole, 20 mg once daily, compared with 88% for omeprazole, 40 mg once daily, 79% for ranitidine, and 79% for misoprostol. Erosions healed slightly faster at 4 weeks with misoprostol, compared with the other regimens, but by 8 weeks most patients had <5 erosions per gastroduodenal region in each treatment group. Diarrhea and abdominal pain were more common in patients taking misoprostol, as were adverse events leading to withdrawal. Patients with duodenal ulcer or erosions at entry and the presence of Helicobacter pylori were good prognostic factors for overall treatment success. Using a model that included only patients with ulcers, those with smaller ulcers also had a higher likelihood of achieving treatment success. Against the background of these new data, omeprazole is the treatment of choice for healing NSAID-associated ulcers, on the basis of its efficacy and tolerability, and the optimal dose appears to be 20 mg once daily.

A 54-year-old man, who had been diagnosed as having MPO-ANCA-related glomerulonephritis in 1993, developed severe anemia and was admitted to our hospital on October, 1997. Endoscopic examination of the upper gastrointestinal tract revealed melena due to duodenal ulcer (Dieulafoy type). The level of ANCA titer was elevated considerably (640 EU), but otherwise there was no evidence of systemic vasculitis activation such as fever, arthralgia, skin eruption, renal insufficiency, and rise in C reactive protein. A renal biopsy showed neither crescentic formation nor necrosis of glomerulus. Subsequently he developed hematochezia and renal dysfunction rapidly progressed thereafter. Angiographical examination of superior mesenteric artery revealed that the bleeding was responsible for the lesion of the small intestine, probably the ileum. In spite of TAE (transarterial embolization) he had recurrence of severe hematochezia three days later. Partial ileotomy was performed and progression of the anemia was stopped. Multiple ulcer was found in the resected ileum. The small arteries in the submucosa at the ulceration showed fibrinoid necrosis of the vessel walls. These findings suggested that ANCA-related vasculitis had relapsed. The patient received methylprednisolone pulse therapy, followed by oral administration of prednisolone after the operation. Both serum levels of creatinine and MPO-ANCA gradually decreased after the initiation of treatment. However, 24 days later, he suddenly manifested severe abdominal pain, and was diagnosed as having perforation of the stomach or duodenum. Due to supportive therapy and reduction of the steroid dose, peritonitis subsided, but symptoms caused by systemic vasculitis developed. Later raised the dose of steroid suppressed the activity of systemic vasculitis. In this case, elevation of the ANCA titer demonstrated recurrence of MPO-ANCA-related vasculitis as gastrointestinal bleeding.

The meaning and definition of dyspepsia continues to challenge clinical investigators and has led to the setting up of several international working teams. However, confusion continues to reign around this term. The effort to classify patients with dyspepsia into subgroups according to their most predominant symptoms has failed to provide clues to the underlying disease, or even to discriminate between functional and organic dyspepsia. With these limitations in mind, the question arises: is there any reason for putting further effort into developing a world-wide definition of dyspepsia when, in addition to the aforementioned shortcomings, further variables such as geographical region, ethnic background, culture and sanitary resources come into play? The answer is that only by establishing a reproducible methodology for individual symptom assessment using a well-defined protocol will comparisons of the prevalence of dyspepsia and the impact of different therapeutic interventions become possible around the world. The data on dyspepsia prevalence, nearly all arising from studies in a few developed geographical areas and countries, are of the order of 1-4% of all consultations in all primary care medicine. However, estimates of adults affected by dyspepsia are as high as 20-40%. The magnitude of these statistics underlines the necessity for further work on the concept of dyspepsia and its major functional subgroups, following the exclusion of any organic causes. Issues such as 'investigate dyspepsia before starting with any kind of treatment or treat dyspepsia before further investigation' or the debate about whether to 'eradicate or ignore Helicobacter pylori in functional dyspepsia' will remain unresolved unless studies performed throughout the world use widely comparable and acceptable definitions and criteria for these conditions. Since the first international working party report in 1988, definitions of dyspepsia have included the description of 'upper abdominal pain or discomfort' and, more recently, have specified 'pain or discomfort centered in the upper abdomen' in order to emphasise further the site of origin as the upper alimentary tract (stomach-duodenum). However, a major change was evident in the more recent Rome I and Rome II reports, in which the symptoms heartburn, acid regurgitation, and belching were excluded from the definition of dyspepsia because of their relation to gastroesophageal reflux disease (GERD) and aerophagia. The intention to define a set of symptoms for dyspepsia is good, but we continue to be faced with overlaps. How should the patient with epigastric pain and heartburn after endoscopic exclusion of duodenal ulcer and reflux esophagitis be classified: dyspepsia or GERD? In cases of abnormal gastroesophageal reflux, 24-h pH monitoring could help to resolve this dilemma, but what if this investigation turns out to be normal? In this field, we need to perform careful studies. In addition, we need to consider the lifestyle and cultural habits of people around the world when translating upper gastrointestinal symptoms into dyspepsia. A step forward in the definition of dyspepsia was attempted by the recent working party for the Rome II consensus on functional gastrointestinal disorders (N. Talley et al.). In this project, the symptoms of dyspepsia were individually described not by a single term, but by painting a 'word picture', to make it easier for patients to express their symptoms, and give doctors and clinical investigators a better understanding of the 'dyspeptic problem' of each individual. It is advisable to follow this approach, since a clear picture of a patient's symptoms, including their duration and intensity, in association with the modern technical approaches that allow investigation beyond organic causes of dyspepsia, will lead to progress in our understanding and better communication about this problem within the medical community, and ultimately to better treatment.

It is now recognised that Helicobacter pylori, like most enteric infections, is mainly acquired in childhood. Adults rarely become infected, with seroconversion rates varying between 0.33and 0.5% per person year. The age at which children are most likely to become infected is still unclear, but findings in a number of cross-sectional studies suggest that infection is acquired before the age of five. The prevalence of infection is highest in children in the developing world where up to 75% of children may be infected by the age of 10. In the developed world the prevalence of infection is noticeably increased among socially deprived children. The diagnosis of H pylori infection in childhood is most often made at endoscopy, for which there are many indications. Symptoms such as abdominal pain, vomiting, and haematemesis may be associated with duodenal ulcer and H pylori infection. However, in the case of children undergoing endoscopy for assessment of oesophagitis, failure to thrive, coeliac disease, Crohn's disease, or portal hypertension, the finding of H pylori infection is likely to be incidental. How should we manage these children with a diagnosis of H pylori infection? Currently, there are no consensus guidelines for the management of H pylori infected children. In 1994 the National Institutes of Health consensus statement recommended that adults with gastric or duodenal ulcer disease, who are infected with H pylori, should receive antimicrobial treatment. The European Maastricht Consensus Report suggested broader indications for treatment of infected adults. It states that treatment is advisable for all H pylori infected dyspeptic patients diagnosed non-invasively under 45 years of age at a primary care level. Patients older than 45 years with dyspeptic symptoms should be treated for H pylori infection but only after endoscopy to rule out any other underlying pathology. The European guidelines also recommend treatment for infected patients with mucosa associated lymphoid tissue lymphoma and patients who are found to have intestinal metaplasia and gastric atrophy.

Relapse of duodenal ulcers was observed endoscopically after Helicobacter pylori eradication therapy for gastric ulcer patients in 2 of 32 successful cases. One patient, a 40-year-old woman, received dual therapy with lansoprazole 60mg and amoxicillin 1000mg for 2 weeks because of an intractable, easily-relapsing gastric ulcer accompanied by duodenal ulcer scars that had not relapsed for 5 years. The H. pylori status was assessed by a rapid urease test, light microscopy, culture, and anti-H. pylori antibody. At 24 months after the cure of H. pylori she had upper abdominal pain and showed relapse not of the gastric ulcer but of the duodenal ulcer. The H. pylori status remained negative. The other patient, a 44-year-old man, showed an active gastric ulcer and duodenal ulcer scars at the first endoscopy. He received the same regimen as described above. Ten weeks after completion of the eradication therapy, endoscopy showed healing of the gastric ulcer and relapse of the duodenal ulcer despite successful eradication. These two cases suggest that H. pylori eradication modifies the pathophysiological condition of gastric acid secretion and facilitates relapse of duodenal ulcers.

In contrast to the experience in the adults, there are limited data concerning the efficacy and safety of upper gastrointestinal endoscopy (UGIE) in paediatric patients. The information on this procedure is very scanty from non-western countries. We analysed 72 children evaluated in Gizan, Saudi Arabia, an area of high endemic hepatitis B and chronic liver disease. The indications comprised abdominal pain (49%), UGI bleeding (24%) and evaluation of suspected portal hypertension. No abnormality was detected in 33 (46%). Mucosal inflammatory lesions (oesophagitis, gastritis and duodenitis) are the commonest abnormal lesions, occurring in 24 (33%). Duodenal ulcer (4 cases) and gastric ulcer (1 case) were relatively few. No case of malignancy was found. Sclerotherapy for variceal bleeding was effective in 4 patients. Helicobacter pylori was detected in 12 of 23 patients and associated with histologically identified gastritis in the majority of these cases. It is concluded that paediatric UGIE is safe and useful in the diagnosis and therapeutic intervention for UGI diseases in children. Our findings provide additional information on the pattern of diseases among Saudi Arabian children.
