ABSTRACT
Objective To investigate the causes and managements of dys-seal syndrome (DSS) developed after esophageal stent placement. Methods From June 2001 to June 2008, esophageal stenting was performed in 98 consecutive patients with malignant esophageal obstruction. A total of 99 metallic stents were used. Of 98 patients. gastroesophageal anastomosis stricture was seen in 19, preoperative radiotherapy history in 26 and tracheoesophageal fistula in 34. Results DSS occurred in 7 patients, with an occurrence rate of 7.14% ,which was significant higher than that in patients with preoperative radiotherapy history and in patients showing marked dilated esophagus proximal to the obstructed site (X~2=0.017, 0.005, P=0.036, 0.013, respectively). After treatment, such as fasting, IPN or nasogastric feeding,only 1 case retumed to semi-liquid diet. Among the rest 6 cases of DSS, an additional stent was employed in one (but in vain), nasogastric feeding tube was used in 2, and removal of the stent under endoscopic guidance was carried out in 3. Conclusion DSS is one of the complications developed after esophageal stent placement, its prognosis is rather poor. Removal of the inserted stent may be the optimal treatment. The prevention of DSS includes proper pre-operation evaluation, selection of suitable stent, enhancement of perioperative nutritional support, etc.
