    Abstract:On the basis of the endoscopic Department NUZ NCC, Russian Railways conducted a routine colonoscopy which were selected 81 patient for polypectomy. Used video system EPX-4400 Fujifilm, video endoscopes EC-590ZW/L, and EC-530WL. This system has the capability of digital and optical zoom, virtual chromoscopy FICE (spectral color separation). Used two user mode, which we consider to be optimal for routine chromoscopy tumors, FICE-0 (light spectrum 530 of the R, G, 485, 505 B; light amplification R 3, G 4, B 3) and FICE-1 (light spectrum 550 R, G, 500, B 470; light amplification R 2, G 4, B 4). Removal of tumors was performed by polypectomy and mucosal resection, using the electrosurgical unit Erbotom ICC 200, ERBE Elektromedizin company. Presents several applications of spectral color technology selection stages of diagnosis and treatment of tumors of the colon.

    Abstract:Aim: analysis of the results of double stenting in patients with combined biliary and pyloroduodenal malignant obstruction. Material and methods: Double stenting with self-expandable metal stents (SEMS) was performed in 9 patients with biliopancreatoduodenal (8) or gastric tumours. Simultaneous presentation of biliary and pyloroduodenal strictures was observed in 6 patients, while in 3 initial development of biliary obstruction was followed by later onset of duodenal stenosis - 4-14 months after first endoscopic (2) or percutaneous transhepatic (1) biliary stenting. In 6 cases single-stage double stenting was performed and endoscopic pyloroduodenal stent insertion was combined with biliary stenting through endoscopic (initial SEMS insertion [4] or replacement of plastic stent [1]) or percutaneous (1) route, in 3 - stents were implanted in two stages. Results: Stenting was successfully carried out in all patients. Early complications were observed in 3 cases and included acute cholecystitis (1), cholangitis (1) and hydrothorax after percutaneous biliary stent insertion (1) with no in-hospital mortality. All patients were followed up until death without any evidence of recurrent obstruction. The median survival was 91,5 days. Conclusion: According to both literature review and authors’ experience, double stenting is an effective minimally invasive palliation of patients with combined biliary and pyloroduodenal malignant obstruction. Multidisciplinary approach is necessary for best results.
