Bleeding pseudoaneurysms are among the most serious and fatal complications following pancreaticoduodenectomy. Diagnostic angiography has been preferred over endoscopy and is rapidly becoming the standard therapeutic treatment for bleeding pseudoaneurysms.
An advanced T stage, nodal metastasis, poor differentiation, and the pancreaticobiliary type were found to be independent predictors of recurrence after curative resection of ampullary carcinoma by multivariate analysis. In addition, the pancreatobiliary type tended to present in a more advanced T stage and more frequently with regional lymph node involvement and perineural invasion than the intestinal type. Furthermore, CEA level and lymph node metastasis were found to be independent predictors of recurrence for the intestinal and pancreatobiliary types, respectively.
AS/SCC of the gallbladder is often diagnosed at an advanced stage, which results in non-curative surgical resection and a poorer prognosis than conventional GBC. However, curative surgical resection of AS/SCC of the gallbladder might result in disease-free survival rates that are comparable with those of conventional GBC.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
