The diagnostic usefulness of serum amylase isozyme measurement was investigated in 17 cases of definite chronic pancreatitis and 13 cases of suspected chronic pancreatitis, a total of 30 cases. Six types of serum isoamylase patterns were distinguished according to the character of the two main amylase activities at the fraction of fast-gamma globulin and pre-gamma globulin. The amylase activity of the fast-gamma fraction rises in acute exacerbation, and falls in cases of chronic calcifying pancreatitis and in cases with a marked decrease in pancreatic exocrine function. Especially, a fall in fast-gamma amylase activity excellently reflects a decrease in pancreatic enzyme production. The measurement of amylase activity at the fast-gamma fraction therefore appears to be a useful method for assessing pancreatic damage. The significance of a frequent rise in pre-gamma amylase activity in chronic pancreatitis remains unknown.

Among 192 cases of chronic pancreatitis, 51 (27%) were classifed as idiopathic after exclusion of all known aetiological factors. The age distribution of idiopathic chronic pancreatitis suggests that there are two separate entities, a "senile" (n = 38) (ISCP) and a "juvenile" form (n = 13) (IJCP). IJCP seems to represent a new nosological entity characterized by a low mean age at onset (25.6 years), a preponderance of males (n = 12), typical recurrent episodes of pancreatitis (n = 13), and a very high incidence of calcifications (n = 10). The course of IJCP seems to be rather benign but protracted. Despite lacking direct evidence, IJCP seems to be due to a genetic factor. The postulated causes of IJCP and ISCP may be identical with the primary factors which are considered to be responsible in combination with high alcohol intake, for the development of alcohol-induced chronic pancreatitis.

In 5 out of 35 patients with acute, acute relapsing and chronic pancreatitis, barium enema revealed partial colonic stenosis at the splenic flexure. In 3 patients laparotomy disclosed colonic perforation with abscess, adhesions between colon and pancreas or a marked pancreatic edema. In two patients barium enema follow-up 3-6 months later showed spontaneous resolution of the stenosis. Comparison with 35 cases in the literature shows that colonic stenosis after pancreatitis is usually incomplete, located at the splenic flexure and due to adhesions between the colon and the pancreas. Spasmodic pains in the upper abdomen, increasing constipation and often rectal bleeding or positive guaiac test of the stool may indicate colonic stenosis. Spontaneous resolution is possible, but if operation is indicated the adhesions should be carefully dissected in order to obviate resections of the colon or the pancreas.

Of one hundred and forty-nine patients (101 male and 48 female) 4-67 years of age, 117 were alcoholics and underwent pancreatectomy because of episodic or continuous abdominal pain or complications or chronic pancreatitis. Nineteen patients underwent pancreaticoduodenectomy, seventy-seven 80-95% distal resection, anf fifty-three 40-80% distal pancreatic resection. There were 3 operative death and 30 late deaths 6 months to 11 years post pancreatectomy. Twenty-one patients were lost to followup, 1 to 11 years post pancreatectomy. Ninety-five patients are known to be alive, 4 of whom are institutionalized. Indications for pancreatectomy in addition to abdominal pain include recurrent or multiple pseudocysts, failure to relieve pain after decompression of a pseudocyst, pseudoaneurysm of the visceral arteries associated with a pseudocyst, recurrent attacks of pancreatitis unrelived by non-resective operations, duodenal stenosis and left side portal hypertension. The choice between pancreaticoduodenectomy or distal resection of 40-80% or 80-95% of the pancreas should be based on the principle site of inflammation whether proximal or distal in the gland, the size of the common bile duct, the ability to rule out carcinoma, and the anticipated deficits in exocrine and endocrine function. The risk of diabetes is very significant after 80-95% distal resection and of steatorrhea after pancreaticoduodenectomy. When the disease process can be encompassed by 40-80% distal pancreatectomy this is the procedure of choice.

Pancreozymin-secretin test (PS test) and intestinal absorption tests were performed in 21 patients with chronic calcific pancreatitis and 32 patients with chronic noncalcific pancreatitis to evaluate exocrine functions of the pancreas. And the following results were confirmed. (1) Fecal fat excretion increased in 33% of chronic pancreatitis (47% of calcific pancreatitis and 25% of noncalcific pancreatitis). Serum carotene leves showed significantly low levels in 44% of chronic pancreatitis (67% of calcific pancreatitis and 27% of noncalcific pancreatitis). (2) D-xylose tolerance test was abnormally low in only 6% of chronic pancreatitis, but Schilling test was evaluated abnormally low in 29% of chronic pancreatitis (50% of calcific pancreatitis and 11% of noncalcific pancreatitis). (3) Fecal fat excretion increased in cases of severe exocrine insufficiency of the pancreas with decreased amylase output and decreased maximum bicarbonate concentration in PS test. (4) Correlation of fecal fat excretion to maximum bicarbonate concentration was statistically significant, but those to amylase output or volume of pancreatic juice were not significant. (5) Antacid drugs combined with pancreatic extracts seems to be indispensable in the treatment of chronic pancreatitis as far as malabsorption in chronic pancreatitis is concerned.

In order to classify a patient with pancreatitis according to the Marseille clasiffication the following criteria must be fulfilled: (a) an acute attach of pancreatitis must be observed, (b) the cause of pancreatitis has to be established, (c) the patient has to be followed over longer periods of time in order to find out, whether the process becomes chronic (involving progredient endocrine and exocrine insufficiency). Diagnostic problems of acute pancreatitis, relapsing pancreatitis, and chronic pancreatitis are discussed taking into account the author's own results. It is concluded, that repeated tests of pancreatitis function and demonstration of pancreatic calcification are more important for establishing the diagnosis of chronic pancreatitis than studies of pancreatic morphology including endoscopic retrograde pancreatography (ERP). ERP may help to find the cause of relapsing pancreatitis of unknown origine; it may help as well preoperatively to diagnose local changes of the pancreatic duct system in chronic pancreatitis.

Twelve patients (11 men, one woman), aged 18 to 68 years, had major arterial hemorrhage as a direct complication of pancreatic pseudocysts and chronic pancreatitis. Chronic alcoholism (11 patients) and blunt abdominal trauma (one patient) were the basis for pancreatic disease. Spontaneous hemorrhage occurred in eight patients. Bleeding occurred into the gastrointestinal tract (eight patients), into the peritoneal cavity (four patients), and was intracystic (one patient). Splenic, pancreaticoduodenal, gastroduodenal, and gastroepiploic arteries were sources of hemorrhage. Operative procedures included local control of bleeding (six patients), distal pancreatectomy (three patients), and pancreaticoduodenectomy (one patient). Four patients died of hemorrhagic complications of pancreatic disease, including one not subjected to operation. Extirpation of diseased pancreatic tissue may lessen the morbidity and mortality attributed to this complication of pancreatitis.

The authors report ten personal cases and review the literature on 99 other cases, and study primary intra-cystic hemorrhage or post-operative hemorrhage, occurring during the course of pancreatic pseudo-cysts. These hemorrhagic pseudo-cysts are very often associated with chronic pancreatitis; they may rupture into a hollow viscus, the peritoneal cavity or into Wirsung's duct. Arteriography and duodenoscopy with retrograde pancreatography, should permit one to reduce the frequency of these latent, undiagnosed forms until surgical operation has been carried out. Even more dangerous, post-operative bleeding often represents a recurrence of primary intra-cystic hemorrhage which has been undiagnosed or neglected. Surgical treatment should give a greater place to operations of excision which simultaneously treat false cyst, the responsible vascular lesion and the chronic casual pancreatitis.

Antinuclear factors in serum were determined (in addition to other tissue antibodies) in 9 patients with acute and 22 with chronic pancreatitis. Of the 11 with pancreatitis of unknown aetiology 9 had serum antinuclear factors, most of them in high titres. Of the 20 with pancreatitis of known aetiology only 3 had antinuclear factors.

Six alpha-amylase (EC 3.2.1.1) isoenzymes have been resolved electrophoretically on cellulose acetate membranes in a discontinuous buffer system. The fastest migrating isoenzymes are of salivary origin (S1, S2, S3), the slower ones of pancreatic origin (P1, P2, P3). We determined the amylase isoenzyme distribution in the sera of 240 subjects. A specific pancreatic isoenzyme (P3) was observed in all clinically diagnosed cases of acute or chronic pancreatitis as well as in 15 of 40 renal-transplant patients. Moreover, P3 isoenzyme activity declined during apparent recovery from pancreatitis. The P2 isoenzyme appeared in 95% of all specimens, P1 in only 2%. The pancreatic isoenzymes were preferentially excreted in the urine of both renal-transplant patients and normal individuals. The major salivary isoenzyme, S1, was observed in 95% of all serum and urine samples; however, the S2 and S3 appeared less consistently. Our method is simple and rapid, and quite applicable for use in clinical evaluation of patients with pancreatitis or with certain nonpancreatic dysfunctions.
