NUNEZ VIDALES, Rodrigo; MARTINEZ-ORDAZ, José Luis y ESTRADA CASTELLANOS, Alicia. Prevalence of primary malignant and metastatic small bowel tumors. Cir. gen [online]. 2014, vol.36, n.4, pp.214-217. ISSN 1405-0099.
Introduction: Small bowel malignant tumors represent about 1 to 2% of all gastrointestinal tumors. The associated symptoms are usually vague. Most of these tumors are not diagnosed preoperatively. The objective of this study is to address the prevalence of small bowel tumors in a population of patients subjected to intestinal resection in a reference hospital.
Material and methods: Records of all patients treated in our hospital with intestinal resection in the past 5 years were reviewed to identify small bowel tumors (primary and metastatic to the small bowel). The clinical characteristics, location and histology type of the tumor were registered.
Results: A total of 185 patients were treated with intestinal resection. Fifteen primary tumors 88%) and 10 metastatic tumors (5%) to small bowel were identifi ed. Most of the patients were symptomatic preoperatively. Occult intestinal bleeding was present in 54% of the patients. Adenocarcinoma was the most frequent diagnosis (8 patients), followed in frequency by gastrointestinal stromal tumors (4 patients). Colon adenocarcinoma was the most common metastatic tumor to the small bowel.
Conclusions: Despite their low prevalence, small bowel tumors represented 14% of all intestinal resections performed in a third level hospital. The symptoms are usually vague and most of the patients are not diagnosed preoperatively.
