Clinical Trial
Respiratory management and outcome of non-malignant tracheo-bronchial fistula following esophagectomy.
Tracheo-bronchial lesions with air leak are rare but a catastrophic complications of esophageal resections. We analyzed the management and outcome of 31 patients who developed a non-malignant lesion of the trachea or main stem bronchus after esophagectomy for esophageal cancer. All patients initially required endotracheal intubation to control respiratory distress. ⋯ Ten of the 31 patients (33%) died during the postoperative course, in eight out of 10 patients, postoperative mortality resulted from an unhealed lesions at the bifurcation or in the left main stem bronchus. These data show that reduction of airway pressure and spontaneous breathing are the key to closure of the airway leak. The entire armamentarium of respiratory, bronchoscopic, and surgical techniques must be available for a successful management of these patients.

By eliminating a thoracotomy, transhiatal esophagectomy (THE) is purported to reduce postoperative pulmonary complications. However, data from many early series do not support this contention, documenting pulmonary complications in up to 50% of patients and pneumonia in 5%-20%. Since 1990, we have implemented a management strategy designed to maximize airway protection in the postoperative period. The purpose of this study was to determine the current incidence of pulmonary complications after transhiatal esophagectomy without thoracotomy. ⋯ Minor pulmonary complications identified by chest film occur in nearly all patients undergoing THE. Strict adherence to a management protocol designed to maximize airway protection in the postoperative period results in a 10% incidence of major pulmonary complications. Older patient age and COPD are risk factors for major pulmonary complications after THE. Although pneumonia is uncommon, it remains the most frequent cause of death after THE.

A prospective study was performed in 190 control subjects and in 236 patients with different degrees of endoscopic esophagitis in order to determine the prevalence of Helicobacter pylori infection at duodenal gastric and esophageal mucosa and its correlation with histological findings. All patients with pathologic gastroesophageal reflux had 24-h pH monitoring studies confirming the presence of acid reflux into the esophagus. Besides the endoscopic findings, biopsies were taken from the duodenal bulb, gastric antrum, gastric fundus and distal esophagus or at the specialized columnar epithelium in patients with Barrett's esophagus. ⋯ The presence of HP infections was correlated with the finding of chronic active superficial or athrophic gastritis while, in the absence of H. pylori infection, gastric mucosa was normal. In the presence of intestinal metaplasia, no H. pylori infection occurred. Based on these findings, it seems that there is no significant evidence for an important pathogenic role for H. pylori infection in the development of pathologic chronic gastroesophageal reflux, erosive esophagitis or Barrett's esophagus, and the presence of antral gastritis in patients with Barrett's esophagus is closely related to the presence of H. pylori infection, and probably not related to an increased duodenogastric reflux.
