POSSIBILITIES AND LIMITATIONS OF RETROGRADE TRANSPAPILLARY STENTING OF THE MAIN PANCREATIC DUCT IN THE TREATMENT OF CHRONIC PANCREATITIS AND ITS COMPLICATIONS

Summary For the last years the role of endoscopic pancreatic stenting in the treatment of chronic pancreatitis and its complica-tions has signifi cantly increased.Materials and methods: In the clinic of abdominal surgery and endoscopy of Pirogov RNRMU based on the University Hospital 31 for the period from 01.1998 to 01.2014 Wirsung duct occlusion, which developed on the background of CP was the cause of performing of 215 endoscopic procedures in 95 patients: 34 (35.8 %) women and 61 (64.2 %) men. Mean age 49,8 ± 11,7 years.Study group consisted of 52 (54.7 %) patients with strictures of MPD and 43 (45.3 %) with pancreatic fi stulas. We tried to perform pancreatic stenting in all the cases, as a method of treatment of pathological changes in the pancreatic ductal system.Results: Endoscopic stenting was successfully performed in 64 cases (67.4 %), while in 45 (70.3 %) cases, this intervention was the defi nitive method of treatment.Temporary Wirsung duct stenting was performed in 19 (29.7 %) cases in which endoscopic retrograde step interven-tions were training to perform surgery.It is signifi cant that the main causes of the technical impossibility of pancreatic stenting was the complete dissociation of Wirsung duct (8), distal localization of occlusive lesions (13), presence of severe angulation in stenotic changes (20) and the length of the scar stricture of the MPD more than 1 cm (17) and particularly a combination of several factors.Clinically signifi cant complications aft er endoscopic interventions in our study occurred in 6 (2.8 %) cases. Lethal outcome occurred in one patient (0.5 %).
