After operation on the stomach in 1,602 patients (3.9 % mortality) acu
te postoperative pancreatitis (APP) developed in 60 of them. Twenty pa
tients died from APP. The impulsive pain symptom and diastasuria were
characteristic of the clinical picture in 35 patients. According to th
e severity of the impulsive pain, the diastasis level in the urine, an
d the complex of therapeutic measures needed to arrest the developing
APP, three degrees of ductal hypertension were distinguished. There we
re no deaths among patients with APP of the first degree. In 23 patien
ts APP was marked by manifest intoxication from the first postoperativ
e day and subsequent development of many complications which called fo
r reoperations. In this group 18 patients died. In 2 cases APP was dis
tinguished by a rapid course and fulgurant development. Attention was
drawn from the very beginning to the extreme severity of the patients'
condition. Symptoms of shock prevailed in the clinical picture. Both
patients died. The authors suggest a scheme of APP prevention with the
use of aldehydes, antioxidants, inhibitors of proteolytic enzymes, a
complex of vitamins.
