OLIVEROS WILCHES, Ricardo; SANCHEZ, Ricardo  e  ESCOBAR PEREZ, René Marcelo. Experience of the National Institute of Cancer Research in managing obtruccions of the gastric tract outlet and colon with self expanding metal stents (SEMS). Rev Col Gastroenterol [online]. 2014, vol.29, n.1, pp.19-25. ISSN 0120-9957.

Objective: The objectives of this study were to study, learn from, and understand the experience in the use of self-expanding metal stents to manage malignant obstructions of the colon and to describe the demographic, clinical and pathological characteristics of patients at the National Cancer Institute (NCI) during the period from January 1, 2010 to September 30, 2012. Methods: This was an observational, descriptive, retrospective study of a series of cases that included patients with gastric tract or colon obstructions. Clinical characteristics, factors involved in the technical and clinical success of SEMS insertion, and the influence of these devices in morbidity and mortality are analyzed. Results: Ninety-six patients were included: seventy-three had duodenal SEMS and 23 had colorectal SEMS. The mean age of these patients was 63.7 years. Technical success for duodenal SEMS insertion was 97.2 % and clinical success was 93.1 %. Technical success and clinical success for colorectal SEMS were both 91.3%. Complications occurred in eight patients, three of whom required surgery. The average life expectancy after the procedure was 102 days for duodenal SEMS and 159 days for colorectal SESMS. No mortality secondary to procedures occurred. Conclusions: The insertion of a SEMS is a minimally invasive procedure that has proven to be an effective palliative treatment and an alternative for reducing ostomy complications and for reducing costs
