We analyze the reasons why the use of confidence intervals is highly advisable. Among these reasons, confidence intervals provide an approach to knowledge of the real importance of a result, independently of statistical significance, as well as equivalence assessment between two variables. 相似文献

We performed a systematic review of the literature on the diagnosis and treatment of secondary aortoenteric fistulas (AEF). A MEDLINE search was performed of articles published in English or Spanish between January 1991 and August 2006. Diagnostic methods, treatment modalities and the results of surgical treatment were analyzed. The most frequent first aortic surgery associated with AEF was repair of abdominal aortic aneurysm (54.31%). The most common form of presentation was gastrointestinal bleeding. Repair through in situ prosthetic replacement had the lowest early mortality rates (8-13.3%) compared with graft excision and extraanatomic revascularization (18.2-44%). AEF is a serious entity and diagnosis requires a high index of suspicion based on clinical findings and indirect data from imaging techniques (computed tomography). The most appropriate therapeutic option continues to be controversial. 相似文献

Digestive surgeons should form part of the multidisciplinary team managing patients with oropharyngeal dysphagia. These patients can be diagnosed through clinical methods and complementary investigations such as videofluoroscopy and pharyngoesophageal manometry. These techniques also allow specific treatment to be selected. Up to one-third of patients with dysphagia suffer from malnutrition as a result of alterations in food bolus transport. Furthermore, up to two-thirds show alterations in swallowing safety (penetrations and aspirations, especially when swallowing liquids), as well as a high risk of respiratory infections and aspiration pneumonia. Increasing food bolus viscosity to 3500-4000 mPas (pudding viscosity) improves the effectiveness of swallowing and reduces the risk of aspirations. Botulinic toxin injection in the upper esophageal sphincter is indicated in patients with spasticity of neuromuscular origin. Cricopharyngeal myotomy is the basis of treatment for Zenker's diverticulum and is also indicated in patients with alterations in the upper esophageal sphincter and preserved oropharyngeal motor response. 相似文献
