A rare manifestation of digestive tract distension involving all the c
avities was observed in a patient who had journeyed at high altitude.
There was no organic obstruction suggesting that the increase in organ
volume was related to decreased atmospheric pressure according to Mai
otte's law. Distension may have been favoured by the diminished abdomi
nal muscle tone, resulting in a lack of adaptation. Dilatation was pre
dominant in the large organs, particularly the stomach and the colon.
