Results of a national survey on the use of stents for the treatment of colonic obstruction. / Resultados de una encuesta nacional sobre el uso de stent para el tratamiento de la obstrucción de colon.

INTRODUCTION: We distributed a survey in order to determine the current indications for the use of colonic stents to treat colonic obstruction in Spain and its compliance with international guidelines. METHODS: Descriptive study of a survey distributed by the Spanish Association of Surgeons (Asociación Española de Cirujanos), the Catalan Society of Surgery (Societat Catalana de Cirurgia) and the Spanish Society of Digestive Endoscopy (Sociedad Española de Endoscopia Digestiva). RESULTS: 340 valid responses were received: 25% from gastrointestinal specialists, and 75% from general surgeons. During the last year, 44.4% of respondents assessed between 10 and 20 COC. Of these, 52.2% indicated less than 5 stents/year, 75% of which were indicated as a prior step to preferential surgery and only 25% were performed with palliative intent. 55.3% of the participants reported knowing the official guidelines, and 64% of respondents would use the stent as a step prior to surgery in elderly patients with localized disease. 75.9% would place stents as palliative therapy in young patients with carcinomatosis, and 61.8% would use them in stage IV malignancies under treatment with chemotherapy. Only 18.1% knew of the risk of colon perforation after stent placement in patients undergoing treatment with antiangiogenics. CONCLUSIONS: In Spain, the indication for colonic stents is reserved for selected cases and varies according to the specialty and the years of experience of the respondent. The compliance with international guidelines of most respondents is moderate. It is important to insist on the high risk of perforation after angiogenics, which is unknown to most surgeons.
