Foreign body impaction in the esophagus: are there underlying motor disorders?

RESULTS: Compared with the control group, the impacted subjects presented marked reduction in amplitude and duration of esophageal contraction in the proximal esophagus. CONCLUSIONS: These motor disorders could be responsible for the foreign body impaction in the esophagus. However, we believe this patient group should be further studied by 24-hour esophageal manometry to reach a more accurate diagnosis by studying each patient's entire circadian cycle.

Prevalence, clinical spectrum and atypical symptoms of gastro-oesophageal reflux in Argentina: a nationwide population-based study.

BACKGROUND: Population-based data on gastro-oesophageal reflux in Latin America are lacking. AIM: To assess gastro-oesophageal reflux symptom prevalence, clinical spectrum and association with the atypical symptoms in our country. METHODS: Gastro-oesophageal reflux self-report questionnaires validated at Mayo Clinic, USA, were submitted to a sample of 1000 residents (aged 18-80 years) from 17 representative geographical areas of Argentina. The samples were selected and stratified according to age, gender, geographical areas and size of town of residence provided by the Argentine Bureau of Statistics and Census. RESULTS: The overall prevalence of any typical gastro-oesophageal reflux symptom experienced in the previous year was 61.2% (95% CI, 57.9-64.6), the prevalence of frequent gastro-oesophageal reflux symptoms was 23.0% (95% CI, 20.1-25.9) and the prevalence of gastro-oesophageal reflux disease was 11.9% (95% CI, 9.6-14.1). Frequent gastro-oesophageal reflux symptoms were associated with dysphagia (OR 2.12, 95% CI, 1.27-3.54, P < 0.01), globus (OR 2.22, 95% CI, 1.35-3.66, P < 0.01) and non-cardiac chest pain (OR 1.55, 95% CI, 1.04-2.31, P < 0.05). CONCLUSIONS: In Argentina, typical symptoms of gastro-oesophageal reflux are highly prevalent at the national level, and frequent gastro-oesophageal reflux symptoms are significantly associated with dysphagia, globus and non-cardiac chest pain.

Pneumatic dilatation in achalasia of the esophagus: a report from Argentina.

We review the treatment of esophageal achalasia by means of pneumatic dilatation (PD), analyzing its results and comparing them with those of the literature. We conclude that our personal experience is similar to that of the literature: PD and surgery produce similar results (67-95%), morbidity (2-9.5%), and mortality (0.7-1%); and PD is cheaper than surgery. According to these conclusions, we believe that the decision of the appropriate treatment should be based on a combination of the choice of the properly informed patient and the operator's experience. However, we also conclude that surgery is mandatory in selected cases, such as achalasia associated with hiatus hernia, esophageal diverticula and neoplasia, history of previous PD failure (since in our experience the results after a second PD are very poor), postoperative relapse, and patients with grade IV mega-esophagus according to Resano-Malenchini's classification.

Heterotopic gastric mucosa in the upper esophagus: report of a case with a fistula.

Foreign body impaction in the esophagus: are there underlying motor disorders?

UNLABELLED: We observed in our practice several cases of impaction with meat boluses without bony edges, in patients with patent esophageal lumen. The aim of this study was to search for eventual underlying motor disorders which could be responsible for this impaction. We included 19 patients who attended the endoscopy service for meat bolus impaction without organic esophageal stenosis. This group was compared with 18 control volunteers. Both groups underwent UGI series, UGI endoscopy and low-compliance perfusion standard esophageal manometry. RESULTS: Compared with the control group, the impacted subjects presented marked reduction in amplitude and duration of esophageal contraction in the proximal esophagus. CONCLUSIONS: These motor disorders could be responsible for the foreign body impaction in the esophagus. However, we believe this patient group should be further studied by 24-hour esophageal manometry to reach a more accurate diagnosis by studying each patient's entire circadian cycle.

Esophageal perforation after pneumatic dilatation for achalasia: why?

A retropective study was perfomed to asses risk factors in patients with esophageal echalasia undergoing pneumatic dilatation. Of 140 patients who underwent 159 dilatations, 7 sustained esophageal perforation (4.4 percent). They were matched with a group of 52 non perforated, dilated achalasia patients. History of prior pneumatic dilatation and small esophageal diameter were found to be risk factors by chi square and ANOVA. Conclusions: 1) Pneumatic dilatation for esophageal achalasia is a procedure with 4.4 percent risk of perforation and 0.6 percent mortality rate. 2) The risk of developping an esophageal perforation is increased by previous pneumatic dilatation and small esophageal diameter. Another risk factor such as a possible anatomical weakness of the esophageal wall (and the likelihood of it being evaluated by ultrasonography) at the site of perforation is suggested. (AU)
