Synchronous Multivisceral Resections in Metastatic or Locally Advanced Gastrointestinal Cancers

Abstract

Background: Resection for advanced tumors can result in prolonged survival but may also increase the well-known risk of postoperative morbidity and mortality. Multivisceral resection may be performed either due to direct invasion of the tumor in adjacent organs or metastases. The reported morbidity and mortality of multivisceral resection are higher compared with more standardized resection; however, this observation may reflect that tumors for which multivisceral resection is performed are commonly advanced. Multivisceral resection is occasionally the only possibility for a curative treatment. The primary aim of this study was to investigate whether extensive resections increase the severity of postoperative complications.
