b) In 30 % of cases gastrinomas are not localized intra operatively

Provided a negative-margin resection can be obtained with a subtotal gastrectomy, and provided it is not a linitis plastica situation (ie, diffuse infiltrating poorly differentiated cancer eliciting a leather-bottle stomach), routine total gastrectomy is to be avoided. The 2010 Japanese treatment guidelines, and the 2011 English version, call for a proximal margin of 3 cm from gross disease for localized well-circumscribed Borrmann I or II tumors, and a margin of at least 5 cm for other tumors. Total gastrectomy is performed whenever necessary to meet these requirements. Total gastrectomy should also be performed for cases of linitis plastica.
