The results of treatment of 12 patients, suffering complicated forms of chronic pancreatitis (CHP), in a General Surgery Department of Ivano-Frankivsk regional clinical hospital in 2011 - 2013 yrs, were analyzed. There were 10 (83.3%) men and 2 (16.7%) women, ageing 22-57 yrs old. Previously 6 (50%) patients were treated for an acute necrotic pancreatitis. The changes in a pancreatic duct (PD) type IV in accordance to Cambridge classification was established in 7 patients, type III--in 3, type IIa--in 2, type IIb--in 1. Virsungolitoextraction with previous pneumodilatation without stenting of PD was accomplished in 4 patients, stenting with pneumodilatation for stricture of PD--in 6, stenting for defect in PD--in 2. Good and satisfactory results were achieved in all the patients. The pain syndrome was absent in 10 (83.3%) patients, 2 (16.7%)--suffered from periodic moderate pain in epigastric region. Endoscopic interventions on the PD must be considered the first stage of surgical treatment in patients with CHP. They must be applied wider due to their reduced invasiveness than open procedures. Open operative intervention must be considered as a second stage of surgical treatment in patients with previous unfair or ineffective endoscopic treatment.
