INTRODUCTION: We report on our experience with the temporary use of a self-expanding plastic stent (SEPS) in the treatment of non-malignant esophageal leaks. MATERIAL AND METHODS: Between November 2001 and May 2005 ten patients with iatrogenic esophageal perforations (n = 4), post-surgical leaks (n = 5) and esophago-mediastinal fistulas after caustic injury (n = 1) were treated by temporary SEPS placement. In eight out of ten patients SEPS placement was done without fluoroscopy due to the emergency setting. Stent removal was performed with a rat-toothed forceps. RESULTS: Leaks were located in the proximal (n = 1), middle (n = 6) and distal (n = 3) parts of the esophagus. The mean leakage size was 2 cm. Stent placement without fluoroscopy was always successful. The median duration of stent therapy was 55.5 days (range 15,438). In 7/10 cases the SEPS was readily removed, showing complete healing of the former leak. Four patients died during the follow-up. However, their deaths were not related to the stent therapy. DISCUSSION: The temporary use of the SEPS represents a safe method for sealing benign esophageal leaks. In the emergency-setting SEPS placement without fluoroscopy is feasible and the stent can be easily removed. In contained perforations without severe mediastinitis of the mid esophagus the SEPS should be discussed as a gentle first-line therapy.
Obesity is an enduring chronic disease, with multifactorial etiology. Many procedures and solutions have been proposed in the last 25 years. If patients do not meet the criteria for bariatric surgery, intragastric balloons may be used to achieve weight reduction. Contraindications to balloon therapy are a large hiatal hernia, severe esophagitis, peptic ulceration and previous gastric surgery. Although intragastric balloons are advocated as safe devices, major complications such as intestinal obstruction, gastric perforation and gastric ulceration have been described. We report a case of esophageal rupture due to insertion of an intragastric balloon for the treatment of morbid obesity, for which no contraindication existed. When abnormal pain or discomfort arises, or esophageal damage is noted after insertion of an intragastric balloon, patients must be closely monitored to diagnose a possible esophageal rupture early and thereby prevent severe complications.
