Prolapse gastropathy syndrome may be a predictor of pathologic acid reflux

Age-specific causes of upper gastrointestinal bleeding in children

The etiology of upper gastrointestinal bleeding (UGIB) varies by age, from newborns to adolescents, with some of the causes overlapping between age groups. While particular causes such as vitamin K deficiency and cow's milk protein allergy are limited to specific age groups, occurring only in neonates and infants, others such as erosive esophagitis and gastritis may be identified at all ages. Furthermore, the incidence of UGIB is variable throughout the world and in different hospital settings. In North America and Europe, most UGIBs are non-variceal, associated with erosive esophagitis, gastritis, and gastric and duodenal ulcers. In recent years, the most common causes in some Middle Eastern and Far Eastern countries are becoming similar to those in Western countries. However, variceal bleeding still predominates in certain parts of the world, especially in South Asia. The most severe hemorrhage arises from variceal bleeding, peptic ulceration, and disseminated intravascular coagulation. Hematemesis is a credible indicator of a UGI source of bleeding in the majority of patients. Being familiar with the most likely UGIB causes in specific ages and geographic areas is especially important for adequate orientation in clinical settings, the use of proper diagnostic tests, and rapid initiation of the therapy. The fundamental approach to the management of UGIB includes an immediate assessment of severity, detecting possible causes, and providing hemodynamic stability, followed by early endoscopy. Unusual UGIB causes must always be considered when establishing a diagnosis in the pediatric population because some of them are unique to children. Endoscopic techniques are of significant diagnostic value, and combined with medicaments, may be used for the management of acute bleeding. Finally, surgical treatment is reserved for the most severe bleeding.

Prevalence and clinical picture of gastroesophageal prolapse in gastroesophageal reflux disease

The prevalence of gastroesophageal (GE) mucosal prolapse in patients with gastroesophageal reflux disease (GERD) was investigated as well as the clinical profile and treatment outcome of these patients. Of the patients who were referred to our service between 1980 and 2008, those patients who received a complete diagnostic work-up, and were successively treated and followed up at our center with interviews, radiology studies, endoscopy, and, when indicated, esophageal manometry and pH recording were selected. The prevalence of GE prolapse in GERD patients was 13.5% (70/516) (40 males and 30 females with a median age of 48, interquartile range 38-57). All patients had dysphagia and reflux symptoms, and 98% (69/70) had epigastric or retrosternal pain. Belching decreased the intensity or resolved the pain in 70% (49/70) of the cases, gross esophagitis was documented in 90% (63/70) of the cases, and hiatus hernias were observed in 62% (43/70) of the cases. GE prolapse in GERD patients was accompanied by more severe pain (P < 0.05) usually associated with belching, more severe esophagitis, and dysphagia (P < 0.05). A fundoplication was offered to 100% of the patients and was accepted by 56% (39/70) (median follow up 60 months, interquartile range 54-72), which included two Collis-Nissen techniques for true short esophagus. Patients who did not accept surgery were medically treated (median follow up 60 months, interquartile range 21-72). Persistent pain was reported in 98% (30/31) of medical cases, belching was reported in 45% (14/31), and GERD symptoms and esophagitis were reported in 81% (25/31). After surgery, pain was resolved in 98% (38/39) of the operative cases, and 79% (31/39) of them were free of GERD symptoms and esophagitis. GE prolapse has a relatively low prevalence in GERD patients. It is characterized by epigastric or retrosternal pain, and the need to belch to attenuate or resolve the pain. The pain is allegedly a result of the mechanical consequences of prolapse of the gastric mucosa into the esophagus.
