Miscellaneous Duodenal Diseases

Abstract

Various lesions in duodenum not covered elsewhere are included in the miscellaneous territory and described in this chapter. Endoscopic and clinical findings are presented as needed. These lesions may be related with specific clinical situations such as systemic illness like Henoch-Schönlein purpura or portal hypertension. Local abnormalities such as diverticulum or angiodysplasia will be also discussed. Parasite infestations such as ascariasis may be diagnosed in duodenum.
