While doing pancreatic gland resection for cancer the lymphadenectomy is performed in volume, recommended on a congress of pancreatologists in Castelfranco-Venetto (standard, radical, extended radical) or in manuals of Japanese investigators (D1, D2). These classifications have got several shortages: terminological inaccuracies, lack of information, concerning the borders of the vegetative neural plexuses dissection etc. The authors have proposed a modified terminology and classification of lymphadenectomy, in accordance to which four types of lymphadenectomy are delineated: D1p, D2p, D3p, corresponding to lymphatic collectors N1, N2, N3, as well as D4p--complete excision of lymphatic nodes in all three regions while total pancreatectomy performance. The symbols 9n-dex/sin and 14n-dex/sin were recommended to name the lymph nodes of the ninth and fourteenth groups, indicating availability of the nervous plexuses dissection performance of right/left hemicircumference of vessels only. The retroperitoneal dissection borders and criterions for the lymphadenectomy volume choice were proposed. |
