Pancreatitis was induced by injection of autologous bile into the main pancreatic duct of dogs. An initial fall in blood pressure was accompanied by appearance of large quantities of active trypsin, chymotrypsin, and elastase in pancreatic exudate with full saturation of protease inhibitors. The enzymes soon appeared in ascitic fluid and lymph, but only in the form of complexes with alpha1-antitrypsin, and alpha2-macroglobulin. No such complexes were detected in venous blood indicating short half-life in the circulation. These studies confirm the release of pancreatic enzymes during bile-induced pancreatitis, and quantify an important protective role for plasma protease inhibitors in this situation.

Cancerembryonic antigen (CEA) and beta2-microglobulin (beta2m) have been measured in cancer patients and patients with benign diseases. Of 168 patients with intestinal cancer, almost 90% had increasing concentrations of either CEA or beta2m or both. In 29 patients at different stages of pancreatic cancer there was a high incidence of increased values in the more severe cases. In 60 patients with histologically classified colorectal cancer the TNomegaMomega group of 19 patients had 47% and 42% of elevated beta2m and CEA respectively. A significant correlation of beta2m or CEA to extension of disease was noted. In benign intestinal disease like cirrhosis and pancreatitis both beta2m and CEA is commonly elevated. Of 26 breast cancer patients, seven had elevated CEA and five had elevated beta2m values before treatment. In the patients with extraganglionary metastasis almost 90% had high beta2m or CEA or both. Of 40 patients with uterine cancer, 26 were found to have increased values of beta2m or CEA or both. Finally, 140 colorectal cancer patients, 62 patients with breast cancer and 10 patients with uterine cancer have been followed longitudinally.

Plasma concentrations of bilirubin, alkaline phosphatase (AP), and glutamic oxaloacetic transaminase (GOT) were measured during 122 attacks of acute pancreatitis in 114 patients, on the day of admission to hospital and 2 days after admission. Concentrations in 74 attacks associated with gallstones were compared with concentrations in 31 attacks in which no stones were found. 24 attacks were severe by clinical criteria. On the day of admission plasma GOT concentrations of more than 60 IU/l were found in 88% of attacks associated with gallstones, but in no attacks without gallstones. Plasma concentrations of more than 25 mumol/l bilirubin and more than 14 King-Armstrong units AP were found in 62% and 66% respectively, of attacks associated with gallstones, and 5% and 10%, respectively, of attacks without stones. In attacks associated with gallstones plasma concentrations of GOT and bilirubin usually fell over the first 48 h of admission. No correlation was observed between these biochemical values and the severity of the attack. In the absence of a history of excessive alcohol consumption, increases in plasma GOT on the day of admission to hospital suggest that gallstones are responsible for the pancreatitis.

Samples of plasma or serum from 53 cystic fibrosis (CF) patients, 90 relatives of CF patients , and 159 controls have been incubated with porcine or bovine 125I-trypsin, electrophoresed on polyacrylamide gel, and autoradiographed. In these individuals, the main binding protein for 125I-trypsin has been shown to be alpha 2-macroglobulin (alpha 2M). Using this method of analysis, no difference in electrophoretic migration of 125I-trypsin-alpha 2M complexes has been observed between CF and control individuals. However, trypsin binding to IgG has been observed in 80% of CF patients, 30% of their mothers, 3% of controls, and in two patients affected with pancreatitis. These trypsin binding immunoglobulins are called TbIg, and specifically, Tb1gG when referring to the G class. Experimental evidence indicates that binding of trypsin to IgG occurs through the Fab portion of the molecule. Tb1gG must be antibodies most probably induced by the exogenous trypsin ingested daily by most CF patients (and by patients affected with chronic pancreatitis). Antibodies against porcine pancreatic elastase have been observed using the same analysis, but not as frequently as Tb1g.

Radiologic findings and medical records of 27 patients with angiographic documentation of splenic vein occlusion were reviewed. The most common causes were pancreatic carcinoma, pancreatitis, and malignant lymphoma. Radiographic findings which suggest splenic vein occlusion are gastric varices without esophageal varices and collateral veins in the left upper abdomen during the vascular phase of rapid sequence pyelography. Additional features may be associated with the underlying disease, such as pancreatic calcification and upper abdominal mass lesions. The diagnosis is usually confirmed by high dose celiac or splenic angiography. Examination of the stomach with barium for the detection of gastric varices is more sensitive than has been previusly recognized; features which suggest them are described. Isolated gastric varices may be a clue to isolated splenic vein occlusion and its underlying causes.

Computed body tomography has become useful in the diagnosis of pancreatic disease. Pancreatitis frequently results in lateral and posterior extension of inflammatory tissue into the pararenal fat planes, which can be visualized by CT. In our series it was associated with clinically diagnosed pancreatitis. Of 100 cases studied for abdominal pathology where pancreatic visualization was optimum, 10 had enlargement of the pancreas with destruction of soft tissue planes extending into the left pararenal space and clinical findings of pancreatitis. Carcinoma of the pancreas was identified in 12; no abnormality was identified in 49; the remaining cases were mixed intraabdominal and retroperitoneal pathology. The value of this sign lies in separating inflammatory processes from neoplastic disease; the sign was not found in normals.

A systematic prospective endoscopic study of the incidence of juxtapapillary diverticula in a variety of digestive disorders was undertaken in the Surgical Clinic at the Provincial Hospital, Port Elizabeth. The findings were related to conditions commonly encountered. The following frequency distribution was found: 33 diverticula out of 164 patients associated with gallstones (20.1%); 15 out of 668 patients not associated with gallstones (2.2%); 1 out of 39 patients with pancreatitis (2.6%); and 3 out of 146 patients with gastric ulcer (2.1%). No diverticulum was noted in 111 patients with duodenal ulcer. These findings suggest that juxtapapillary diverticula are nearly 10 times more common in patients with gallstones than in patients without. There is evidence to suggest that these diverticula tend to precede the gallstones. It is conceivable that juxtapapillary diverticula may predispose to gallstones. Alternatively, both conditions may be manifestations of another underlying disorder as yet to be defined.

In a review of arteriograms of 72 unselected consecutive cases of pancreatitis, seven patients were found to have arterial aneurysms involving branches of the peripancreatic vessels. During the same period, arteriograms of 84 cases of carcinoma of the pancreas were reviewed and no aneurysms of any of these vessels were found. The demonstration of aneurysms of the peripancreatic arteries in pancreatitis is an important differential feature from carcinoma of the pancreas. Both carcinoma of the pancreas and chronic pancreatitis can cause encasement of the arterial vessels and obstruction of the splenic or the superior mesenteric vein, therefore resulting in a similar angiographic appearance. Thus an aneurysm seen in such a patient is a helpful distinguishing feature. In addition, these aneurysms are an important source of hemorrhage and mortality in pancreatitis.

A series of 29 cases of amyloidosis of the alimentary tract is reported. Five cases (17%) were primary amyloidosis; 14 cases (48%) were amyloidosis secondary to other diseases (such as chronic inflammatory and neoplastic diseases); 10 cases (35%) were amyloidosis of the heredo-familial type connected with Familial Mediterranean Fever. In 23 patients (79%) the diagnosis was established by biopsies, and in 6 more cases on autopsy. Gastrointestinal involvement was found in all age groups. Gastro-enterologic complications observed in the present series include: diarrhea, malabsorption, ileus and gastrointestinal bleeding. In addition other conditions such as jaundice (3 cases), esophagitis and acute hemorrhagic pancreatitis were observed. In 22 patients proteinuria was observed and in 13 patients the nephrotic syndrome. Among 17 patients, in 11 the clinical picture before death was that of terminal renal failure. The survival after diagnosis among 14 patients reached 4 years in 9 cases, and 19 years in one case. The diagnostic value of the rectal biopsy is emphasized.

Gastrointestinal complications, such as ileus, bleeding, stenosis and fistula formation, were retrospectively analysed on 180 patients with acute pancreatitis. Paralytic ileus occurred in only a quarter of patients with acute oedematous pancreatitis and only one had bleeding from a gastric ulcer. Complications occurred in the early but also postacute stage in patients with the haemorrhagic-necrotizing form. Even with early and delayed operation and adequate treatment of most complications, renewed gastrointestinal complications were not uncommon and required re-operations.
