Surgical results of pancreaticoduodenectomy for carcinoma of the distal third of the stomach.

Pancreaticoduodenectomy (PD) was performed as a radical operation on 10 patients who had stage III or IV carcinoma of the distal third of the stomach which invaded the pancreas head (T4) or had level 3 lymph node metastasis. The surgical results of the PD were compared with those of 69 patients treated with subtotal gastrectomy (SG). Although the postoperative morbidity was higher (70%) in the PD group than in the SG group (32%), no hospital death occurred. The overall postoperative survival provided by PD was as good as that provided by SG for 43 patients who had stage III or IV tumors (the 5-year survival rates, 40 versus 45%). Regarding the T4 tumors invading the pancreas, the survival of the 9 patients with PD was better than that of the 12 patients with SG (median survival time, 19 versus 9 months). Thus, PD might improve the postoperative survival of patients with carcinoma of the distal stomach invading the pancreas.
