Objectives:
To establish the efficacy and safety of antroduodenal metal stents for the treatment of pyloric syndrome in patients with distal gastric cancer.
Materials And Methods:
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.
Results:
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%.
Conclusions:
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.
