Aims/Objectives. The purpose of our research was studying of the reasons to increase head of the pancreas with a comparative estimation of morphological changes and outcomes of surgical treatment at patients by whom the local resection of the head of the pancreas with duodenum- preserving has been executed. Materials and methods. Results of the surgical treatment and morphological changes of 104 patients were studied: a local resection of the head of the pancreas with longitudinal pancreaticojejunostomy (LRHP+LPJ, n = 33), LRHP without LPJ (LRHP—LPJ' n = 36) and a local resection of the head and isthmus of the pancreas without LPJ (LRHIP—LPJ, n = 35). Results and discussion. In comparison groups has been revealed statistically significant distinction (Н = 17,357, df = 2, р = 0,002) on the sizes of the pancreas head. In their groups has been revealed statistically significant distinction in the sizes intrapancreatic pseudocysts in the pancreas head (Н = 8,912, df = 2, р = 0,012). The Spearman correlation (Spearman, p) had been found out statistically significant strong direct dependence between variables «the sizes of the pancreas head» and «the sizes intrapancreatic pseudocysts in the pancreas head «in comparison groups: LRHP+LPJ p = +0,73, р < 0,0001, LRHP-LPJ p = +0,78, р < 0,0001, LRHIP-LPJ p = +0,76, р < 0,0001. Between three groups of the patients by quantity of complications after operation were statistically significant (x2 = 10,644, df = 2, р = 0,005). In comparison groups has not been established distinctions on presence of the complications with focal or diffuse perilobular fibrosis — С < 0,200 or intralobular fibrosis — С < 0,265, and presence periductal fibrosis — С = 0,124. Conclusions. The sizes of the pancreas' head in the compared groups directly depend on the sizes intrapancreatic pseudocysts in the pancreas head. The probability of the complications' development after operation is not depended with focal or diffuse perilobular fibrosis or intralobular fibrosis and presence periductal fibrosis.
