“…Si se compara el desempeño inicial de la prótesis Choostent obtenido en esta serie, con los presentados por otros autores con diferentes tipos de stents, se observan resultados similares en el descenso del índice de disfagia [6][7][8][9][10] (Tabla 7). Los pacientes con fístula traqueo-esofágica presentan, por lo general, una sobrevida menor a un mes sin tratamiento específico 34 y los intentos de cirugía paliativa se asocian a una alta mortalidad 35 .…”

“…La principal causa de reaparición o empeoramiento de la disfagia fue la disfunción de la prótesis, (fractura y migración). Si se excluye esta causa, la tasa de recidiva de la disfagia desciende a sólo un 20%, cifra similar a la de otros autores [6][7][8][9][10] . La tasa de fractura de la prótesis Choostent para este estudio fue de 16,7%.…”

“…La tasa de fractura de la prótesis Choostent para este estudio fue de 16,7%. Esta complicación es prác-ticamente inexistente en estudios similares con otros tipos de próte-sis [6][7][8][9][10] . Como posibles causas que predisponen a la rotura del stent, se describen la combinación de debilidad intrínseca de la propia prótesis y factores corrosivos no totalmente identificados 37 .…”

“…La terapia con prótesis autoexpandible metálica, cumple con la mayoría de las características de un tratamiento paliativo ideal [6][7][8][9][10] . Habitualmente es posible obtener un restablecimiento inmediato de la nutrición oral y una adecuada oclusión de fístulas traqueo-esofágicas [11][12][13] .…”

Use of Choostent prosthetic device for palliation of dysphagia secondary to esophageal cancer Background: Esophageal cancer causes disabling dysphagia and swallowing problems. Aim: To prospectively analyze the outcome of the insertion of a covered self-expanding metallic Choostent type prosthesis as a method of palliation of dysphagia, esophageal fistula or leak secondary to malignant disease of the esophagus or cardia. Material and Methods: A total of 30 consecutive patients aged 75 ± 8.8 years (63% males) with malignant disease of the esophagus or cardia were studied. Results: In 27 patients (90%) the stenosis was located in the esophagus, in two (6.7%) at the gastroesophageal junction and in one (3.3%) at the esophago -jejunal anastomosis due to tumor recurrence. In 24 cases (80%), the indication of the prosthesis was dysphagia, in three (10%) the presence of a tracheo-esophageal fistula and in the remaining three (10%), the suspicion of a perforation. Patients were followed until death. The prosthesis was inserted without incidents in 29 patients (96.6%). One patient had a pneumomediastinum, which evolved favorably. Dysphagia subsided in all patients. Early evolution was satisfactory in 12 patients (66.7%). The most common early complication was a transient chest pain in 3 cases (10%). Four patients (13.3%) died within 30 days post procedure. Of the remaining 26 patients, 14 (53.8%) had late complications (recurrence of dysphagia in 42% and hemorrhage in 11%). The mean interval between stent insertion and death was 169 ± 142.5 days. Conclusions: The Choostent esophageal prosthesis improves dysphagia immediately and safely. However, its use is associated with a high rate of late complications, directly related to prosthetic dysfunction.

A comparative analysis of the immediate and long-term results of treatment of 245 patients with malignant obstruction of the upper digestive tract (101 patients after surgical palliative surgery and 144 patients after endoscopic prosthesis self-expanding stents)in a retrospective, non-randomized and two-center study took place. Complications developed in 18.8 and 12.5% of cases; mortality was 27.7 and 5.6%; the median length of staying in hospital -21 and 15 days. Complications in the long-term period developed in 12% and 11.9% of cases, the median survival period constitutes 87 and 105 days. Statistical comparisons showed that, in comparison with surgery, stenting is accompanied by number of early and late complications, lower mortality, and helps to reduce the duration of hospital staying, and allow to increase the average life expectancy of patients; therefore it can be recommended as a definitive palliative treatment of inoperable patients.

Covered nitinol stents for the treatment of esophageal strictures and leaks

Abstract: Ultraflex and Choostent proved to be equally reliable for palliation of dysphagia and leaks. Removal of the Choostent was easy and safe under mild sedation.
