Oesophageal stent insertion for palliation of dysphagia in a District General Hospital: experience from a case series of 137 patients.

Background: Endoscopic oesophageal stent insertion is a widely used procedure to alleviate dysphagia caused by malignant strictures of the oesophagus and gastric cardia. It can, however, be associated with significant complications, mortality and morbidity. Aim and method: This retrospective case note study was undertaken to assess success rates, complications and mortality of oesophageal stenting when undertaken in a UK District General Hospital (DGH) setting. Patients who underwent oesophageal stenting for malignant disease from January 2000 to January 2006 were included. Results: Of the 137 patients studied, oesophageal adenocarcinoma was present in 57% of patients, squamous cell oesophageal carcinoma in 37% and gastric adenocarcinoma in 6%. Indications for stent insertion were: presence of non-resectable tumours (65%), co-morbidities that contraindicated surgery (25%), refusal by patients for surgery for potentially resectable disease (6%) and a need for enhanced oral nutrition prior to surgery (4%). Prior to stenting 86.4% of patients suffered from advanced dysphagia. A significant improvement in symptoms was seen in 94% of patients. Discharge from hospital was within 48 h in 45% of cases. Chest pain was experienced by 13.9% of patients and serious acute stent-related complications (perforation or bleeding) occurred in 5.8% of patients. Overall 41.6% of patients had at least one complication. Mortality was 4.4% at 7 days and 24.8% at 30 days. Conclusions: Oesophageal stent insertion proved to be an effective palliation of dysphagia in group studied. It is a relatively safe procedure with a low rate of serious acute complications (5.8%) and can be done as a short stay in many patients. [ABSTRACT FROM AUTHOR]
