[Biodegradable stent as treatment of refractory benign esophageal stricture (RBES)].

Abstract

A 26-year-old female patient, from La Paz-Bolivia. She came with a disease period of 15 months characterized by progressive dysphagia. One month before the onset of the symptomatology she ingested bleach with autolytic intentions. In the study of diagnostic upper gastrointestinal endoscopy at 25 centimeters of the dental arch was evidenced a stenosis of about 3 mm in diameter, central and with adjacent esophageal epithelium of a preserved appearance. In the x-ray of contrasted esophagus at the level of the middle third of the esophagus was evidenced a stenosis, short tubular, with a smooth border, of approximately 2 cm in length. Treatment was initiated using axial mechanical dilatations with Savary Guilliard bougies with an interval between sessions of 2 to 3 weeks and with 8 sessions in total. In the last session the largest bougie used was 12.8 mm. It is then that taking into account the diagnostic criteria of Kochman, the diagnosis of refractory caustic esophageal stenosis was made. During the period of realization of the dilations with bougies the patient became pregnant, which made difficult the accomplishment of the procedures for the routine use of fluoroscopic control. At 14 weeks of pregnancy, a SX-ELLA uncovered biodegradable esophageal stent of 10 cm length was implanted. We present the case as an alternative and novel management for this type of pathology.
