The authors present a case of splenic hemangiosarcoma which was encounter-a group including some 600 splenectomies. Hemangiosarcomas represent only 3% of all malignant splenic tumours. This clinical observation is of particular interest because of the extreme rarity of such cases.

[Particular operations in surgery of gastric ulcer under the protection of vagotomy].

There are particular situations in the frame of the surgery of gastric ulcers, when the use of classical techniques--such as extensive resections, or sub-total resections--represents a risk factor and raising doubts about the vital prognosis of the patient (dehiscence, fistula, etc.).
