Metastasis to para-aortic lymph nodes often occurs in pancreatic head cancer, but factors that predict it are not well known.Using histopathologic data of 178 patients who underwent extended lymph node dissection for pancreatic head cancer, we analyzed the distribution of metastases to lymph node groups classified in detail and attempted to identify the lymph node groups that have a strong relation...
Cirrhotic patients may require portosystemic shunts as treatment for complications of portal hypertension. The aim of this study was to asses how these procedures may influence the orthotopic liver transplantation procedure and its outcome.Forty-five patients with a previous portosystemic shunt were divided into 3 groups (group 1, 19 with a portocaval shunt; group 2, 4 with a mesocaval shunt and 5...
The reported experience with laparoscopic pancreatic resections (LPR) remains limited to case reports or small series of patients.A retrospective multicenter study was conducted in 25 European surgical centers concerning their experience with LPR. Detailed questionnaires were used, focusing on patients, tumors, operative data, and late outcome.During the study period, 127 patients with presumed pancreatic...
The aim of this study was to clarify whether the types of portal vein (PV) occlusion during hepatectomy affect the long-term outcome in patients with hepatocellular carcinoma (HCC).Eighty-six patients who had undergone curative hepatic resection for HCC were divided on the basis of the type of PV occlusion into 2 groups: total PV occlusion (TPVO, n=56) and selective PV occlusion (SPVO, n=30) groups...
Regionalized trauma systems have been shown repeatedly to improve the outcome of seriously injured patients. However, we do not have data regarding which components of these systems have the most impact on outcome and to what degree. The objective of this study was to understand the association between various components that make up a trauma system and outcome.Surveys were administered to trauma...
The fact that solid pseudopapillary neoplasms of the pancreas (SPNP) occur predominantly in young women suggests that genetic and/or gender-specific factors may play a role in the pathogenesis. Therefore, SPNP derived from male patients may exhibit different molecular or clinicopathologic characteristics compared to SPNP derived from female patients.We compared the immunohistologic staining patterns...
