The placement of self-expanding metallic stents (SEMS) is a common form of treatment in malignant obstructions to the gastric outlet tract, achieving the resolution of symptoms in the short term and with an acceptable risk of complications; It is convenient to know and the detail of its use and how to treat them. The objective of this publication was to evaluate the occurrence of complications of the procedure and its treatment.
Methods: The work had a descriptive component on the treatment of the use of prosthesis and its treatment and another of association with respect to the administration of oncological treatment with palliative intention and its result with respect to survival; In a retrospective manner, 150 patients were reviewed from January 2011 to 25July 2017, who required this procedure at the National Institute of Cancerology, in Bogotá, Colombia.
Results: A 64% (N = 96) of patients with stage IV disease were identified, which had an incidence of early complications of 11.33% (N = 17) and late complications 29.33% (N 29= 44). A technical success rate of 98.6% (148/150) and clinical success of 96% (146/150) was documented. Most of the complications were treated endoscopically and 2.66% (N = 4) patients needed surgical treatment.
Conclusions: Complications of duodenal stent placement can be successfully managed endoscopically in most cases. Patients who, in addition to prosthesis placement, received oncological treatment had a statistically significant higher survival rate.
