In previous papers (M arina-Fiol, 1962: M arina-Fiol, Miranda, Gaón andGutiérrez, 1964) we have described a clinical picture con sisting of distress, and at times pain, in the hypogastrium two to three hours after meals, which on occasion radiates to the lum bar region and to the right iliac fossa, often leading to a mistaken diagnosis of appen dicitis. In one of our cases there was diarrhea.
