Gastric diverticulum is a rare disease, often benign and specifically located in the right paracardial region. The authors report a case of left paracardial diverticulum with gastro-oesophageal reflux. This association should be treated surgically with resection of the diverticulum, after failure of medical treatment.

Pulmonary haemosiderosis is a rare disease of unknown etiology, mainly affecting children and adolescents. Pulmonary haemosiderosis may occur in association with several respiratory or other disease (Lupus erythematosus, Goodpastures syndrome). Delay in diagnosing can lead to fatal complications. BAL appears to be the method of choice to detect haemosiderin-laden macrophages. No reference values are available for children to date. 64 bronchoalveolar lavages were performed to establish reference values of haemosiderin-laden macrophages in children. Less haemosiderin was found in children compared to adults, and hence a new haemosiderin score was established for paediatric patients. Compared to healthy children, no elevated haemosiderine levels were found in children with chronic pulmonary disease such as bronchiectasis or chronic aspiration caused by gastro-oesophageal reflux. Therefore even a mildly increased amount of haemosiderin-laden macrophages in children requires medical attention.

Swallowing is a complex mechanism based on the coordinated collaboration of tongue, pharynx and esophagus. Disturbances of this interplay or disorders of one or several of these components lead to dysphagia, non-cardiac chest pain or regurgitation. The major primary esophageal motility disorders--achalasia, diffuse esophageal spasm, hypercontractile esophagus ('nutcracker esophagus') and non-specific motility disorder--are of unknown etiology. Other esophageal diseases, such as cervical diverticula or gastroesophageal reflux disease, might also be caused by a primary esophageal motility disorder. Medical treatment of esophageal disorders with esophageal hyper- or dysmotility requires agents that reduce esophageal contractile force (anticholinergic agents, nitrates, calcium antagonists). Despite the beneficial effect of the various drugs on esophageal motility parameters, the clinical benefit of medical treatment of esophageal motility disorders is rather disappointing. Calcium channel antagonist, alone or in combination with anticholinergics or nitrates, can be used as a medical trial, especially in mild achalasia. However, medical therapy is clearly inferior to pneumatic balloon dilation therapy. Recently, botulinum toxin injection was suggested as a therapeutic option in achalasia patients with good results on lower esophageal sphincter pressure (LESP) and symptom scores that were similar to the results achieved by pneumatic balloon dilation. Hypercontractile esophagus shows a good manometric response to calcium channel antagonists, but only little clinical effect in terms of improvement of symptoms. Diffuse esophageal spasm is a relatively rare disease and few clinical studies are available. The use of calcium channel antagonists can be beneficial, at least in some patients with diffuse esophageal spasm. From clinical and epidemiological studies, there is some evidence of a 'psychological' component in the pathogenesis or perception of esophageal symptoms. There is some clinical benefit from centrally acting drugs such as benzodiazepines or antidepressants. With the exception of botulinum toxin for achalasia, medical therapy of primary esophageal motility disorders is rather limited and the clinical results are poor. Further understanding of esophageal pathophysiology as well as development of new receptor-selective drugs might increase our chances of a successful treatment of primary esophageal motility disorders.

Barret's esophagus (BE) is a rare disease in children. It is caused by gastroesophageal reflux (GER). From 1996 to 1999 seventy-eighth children with GER were treated. Twenty-four-hour pH-metry and manometry of the esophagus, scintigraphy and contrast roentgenoscopy of the esophagus were used for diagnosis of GER. All the children underwent biopsy of mucosa membrane of distal esophagus. Morphologic examinations revealed BE in 16 (20.5%) children. Metaplasia of esophageal epithelium by intestinal type (IT) in combination with one by gastric type (GT) were revealed in 8 children, metaplasia by gastric type alone (epithelium of gastric and fundal parts of the stomach)--in 8 children. Six children with IT metaplasia of the esophagus with long strictures underwent extirpation of the esophagus with one-stage esophagoplasty. It esophageal stenosis is not long or is absent, fundoplication by Nissen (4 children) and drug therapy (6 children) are performed. It is concluded that in IT metaplasia of the esophagus with long peptic esophageal strictures resistant to bouginage extirpation of the esophagus with one-stage coloesophagoplasty is desirable. Other methods of treatment do not exclude probability of esophageal adenocarcinoma. These children should be followed up with esophageal biopsy each 6-12 months.

Eosinophilic esophagitis is a rare entity, characterized by eosinophilic infiltration of the oesophagal mucosae, with no gastroesophageal reflux. Food allergies are often involved. We report 3 paediatric cases of eosinophilic esophagitis, revealed by dysphagia, with or without stricture. Eosinophilic esophagitis is a rare disease, but its frequency is probably underestimated. Symptoms are sometimes unusual. Oesogastroscopy with biopsy is essential for the diagnosis. Food allergies can be involved and must be systematically investigated.

Primary eosinophilic esophagitis (EE) is a rare disease with symptoms similar to those of gastroesophageal reflux disease (GERD). However, EE is caused by severe eosinophilic invasion of the esophageal epithelium, typically followed by dysphagia. A man 28 years of age presented persistent symptoms of GERD despite traditional antireflux therapy. Histologic evaluation showed eosinophilia (85 eosinophils/high-power field (x 400)). Treatment by bouginage resulted in mucosal lacerations and transitory clinical improvement. Local steroid therapy for four weeks eliminated the symptoms.

Gastroesophageal reflux with hiatal hernia has been associated with unusual presentations, including rumination syndrome, Sandifer syndrome (reflux esophagitis, iron deficiency anemia and head cocking) and the Herbst triad (iron deficiency anemia, hypoproteinemia and finger clubbing). We report a new case of this rare disease. Lack of awareness of gastroesophageal reflux as a possible cause of these striking symptoms could lead to complications and delayed surgery.

Epiphrenic diverticulum is a rare disease associated with distal esophageal obstruction and a weakened muscularis propria. We have adhered to an operative strategy of excision (diverticulectomy), repair of esophageal wall, and relief of functional and mechanical obstruction. We sought to assess this pathophysiology-directed treatment strategy. From 1987 to 2005, 44 patients underwent surgery for epiphrenic diverticulum. Diverticulectomy, repair, and relief of distal obstruction was performed in 35 (80%) and esophagectomy in nine (10%). Outcome (symptoms, diet, subsequent therapies and morbidity) was assessed by follow-up. Forty of 44 patients had preoperatively identifiable esophageal obstruction (91%). Distal obstruction was functional in 32 patients and mechanical in 24; these conditions coexisted in 16. After surgery, there were no in-hospital deaths; 15 patients experienced 22 in-hospital complications. Survival was 90% at 5 years and 72% at 10 years. Symptoms improved in most patients (P = 0.0004), except for gastroesophageal reflux; new symptoms of gastroesophageal reflux occurred in 9/27 (33%) without this symptom preoperatively. Diet was less restricted postoperatively (P < 0.0001). Of 35 patients undergoing diverticulectomy, three (8.6%) required dilatation and two (6%) reoperation; 6/9 esophagectomy patients required dilatations. Preoperative assessment must include evaluation for mechanical obstruction. Adherence to a pathophysiology-directed operative strategy is safe and will improve the symptoms of most patients, with little need for reintervention. However, occasional patients will experience new symptoms, particularly reflux. Esophagectomy is the alternative for patients who are not candidates for diverticulectomy, repair of esophageal wall, and relief of distal obstruction.

Tracheal stenosis in adults usually is the result of mechanical injuries either from direct trauma or intubation. Rarely do cases develop in patients without such a precedent history, and there are few reports of the pathology of idiopathic tracheal stenosis (ITS). We reviewed clinicopathologically, 63 tracheal resections for tracheal stenosis in patients who had no antecedent explanation for their stenosis. We contrasted these 63 cases with 34 cases of tracheal stenosis owing to chondromalacia (CM) after mechanical injury. All 63 cases occurred in females, with a mean age of 49 years. The most common symptom was dyspnea on exertion. The average duration of symptoms was greater than 2 years. One-third of the patients gave a history of gastroesophageal reflux. All but one of the cases occurred in the subglottic region and/or upper one-third of the trachea. Pathologically, most cases showed extensive keloidal fibrosis and dilation of mucus glands, a finding that was not obvious in most cases of CM. ITS has relatively normal cartilage with smooth inner and outer perichondrium, whereas CM has extensive degeneration of cartilage with irregular border of inner perichondrium observable at shirt sleeve magnification. Immunohistochemical staining for estrogen receptor and progesterone receptor was positive in fibroblasts cells in most cases. ITS is a rare disease and restricted to females. It may represent some form of fibromatosis. ITS can be distinguished histologically from CM in tracheal resection specimens in most cases.

Gastric malrotation is defined as a torsion of stomach around its short or long axis. It is a rare disease in childhood. Gastric malrotation may present either as a surgical emergency or as chronic abdominal symptoms. There is limited data about the respiratory symptoms associated with gastric malrotation. The aim of this study was to review the records of 14 children who presented with respiratory symptoms and diagnosed as gastric organo-axial malrotation. Between August 2005 and August 2007, 14 children diagnosed as having gastric organo-axial malrotation participated in this study. There were 11 boys and three girls with a mean age of 7.1 months. All patients were symptomatic. Presenting symptoms included wheezing in four patients, recurrent pneumonia in four, chronic cough in two, chronic cough and apnea in two, recurrent pneumonia and chronic cough in one, and chronic cough and failure to thrive in one. All of our patients had organo-axial gastric malrotation. Gastroesophageal reflux was found in nine patients (64.2%). Six patients were treated with surgery and antireflux medication and the remaining eight patients with antireflux medication. In conclusion, it is probable that gastric malrotation associated with massive or occult gastroesophageal reflux could be responsible for the respiratory symptoms such as chronic cough, recurrent pneumonia, wheezing, and apnea.
