[Auto-expandable metal stent in the management of distal stomach cancer].

To establish the efficacy and safety of antroduodenal metal stents for the treatment of pyloric syndrome in patients with distal gastric cancer.Data were obtained from 31 patients older than 18 years who had a diagnosis of distal gastric cancer between 2009 and 2017, who presented pyloric syndrome associated with antroduodenal stenosis documented by endoscopy or X-ray of upper digestive tract, being managed with an antroduodenal auto-expandable metal stent in the gastroenterology unit of the San Ignacio University Hospital (HUSI) in Bogotá DC, Colombia.The main documented symptom that led to consultation was the presence of vomiting in 45.1%, followed by weight loss 16.13% and upper digestive tract bleeding 19.35%, the diagnosis being made in 74.19 % of cases with endoscopy of upper digestive tract. 96.7% of the patients presented metastases at the time of diagnosis of pyloric syndrome. 100% of patients had technical success in relation to stenting with subsequent resolution of symptoms in 96.77%, the most frequent complication being displacement in 16.13%.Auto-expandable metal stents for the management of gastric outlet tract obstruction secondary to distal gastric cancer is a safe and effective method as a palliative treatment, improving morbidity and mortality compared to surgical management.
