摘要
Tumors arising in the body/tail of the pancreas tend to be diagnosed at a more advanced stage, with a lower rate of resectability compared to disease of the head. Distal pancreatectomy (DP) associated to multivisceral resections (MVR) can represent a surgical option for selected patients with advanced tumors. We retrospectively analyzed data of patients who underwent DP associated with MVR at our Institution over a 9-year period, and compared them to standard DP. MVR was defined as resection of at least one additional organ or vascular structure because of neoplastic involvement. Out of 508 DP, in 59 cases MVR was performed. The absolute incidence of complications was comparable between the two groups (69.5 % in MVR arm vs. 57.2 % in control arm, p = 0.072) but more patients in the study group had a Clavien-Dindo class ae<yen>3 (18.6 vs. 9.8 %, p = 0.04). A longer operative time (291 +/- 91 vs. 227 +/- 67, p < 0.001), an increased need for intraoperative transfusions (21.4 vs. 3.3 %, p < 0.001) and a slightly longer hospitalization (9 [7-16] days vs. 8 [7-10]; p < 0.001) were observed in the MVR group. In patients with ductal adenocarcinoma (n = 118), mortality was comparable between groups (p = 0.44) over a median follow up of 26 [16-41] months. In contrast, among patients with neuroendocrine neoplasms, mortality was higher in the study group (p = 0.002). Multivisceral resection for cancer of body and tail of the pancreas is feasible in selected cases, with an acceptable surgical complication rate compared to standard procedures and a favorable long-term survival in ductal cancer.
