Despite improvement in chemo-radiotherapy, surgery remains the primary curative modality with special emphasis on lymphadenectomy. However the extent of lymphadenectomy performed by surgeons all over the world differs. Generally speaking, in Japan and Korea, the standard curative protocol would entail a “D2” lymphadenectomy whereas in the western world it would be considered unnecessary and the standard protocol would entail a standard “D1” lymphadenectomy. Thus prompting a newer surgical therapy of modified D2 in dissection in which pancreas and spleen are preserved. Lymph nodes surrounding stomach are divided into 20 stations and these are classified into three groups depending upon the location of the primary tumour. Aims & Objectives: The aims and objectives are to compare: 1) operative time of modified D2 gastrectomy with that of D1 gastrectomy;2) operative morbidity and mortality of modified D2 gastrectomy with that of D1 gastrectomy;3) the disease recurrence between modified D2 & D1 gastrectomy. Materials & Method: The study entitled D1 versus modified D2 gastrectomy for Ca stomach—a prospective, comparative study was conducted in the Postgraduate Department of General Surgery, Government Medical College, Srinagar as a prospective, comparative study over a period of three years 2012-2014. Patients with resectable gastric cancer were taken as subjects for the study and were divided in 2 groups that were closely matched to avoid any bias. Assessment of both the groups was done in identical fashion as per standard protocol. One group underwent gastrectomy with D1 lymph node dissection whereas the other group underwent gastrectomy with a modified D2 lymph node dissection (spleen and pancreas preservation). The type of lymphadenectomy was decided on randomization (simple random sampling). Results: After comparing the two procedures, it was noted that: 1) modified D2 lymphadenectomy took o展开更多
