Chronic pancreatitis may occasionally be due to chronic incomplete obstruction of the pancreatic duct. Pancreas divisum is associated with a high incidence of recurrent pancreatitis or pancreatic pain, which may be due to relative stenosis of the accessory papilla through which most of the pancreatic secretions drain. Stenosis of the pancreatic duct at the site of fusion of he ventral and dorsal ducts has been demonstrated in 3 percent of autopsy subjects and in patients studied with ERCP. Two patients with idiopathic chronic pancreatitis presented with dilatation of the pancreatic duct which extended distally from the site of fusion of the embryonic ducts. We postulate that congenital stenosis of the main pancreatic duct may predispose to chronic pancreatitis in the absence of other obvious etiologic factors.

Pancreas divisum is a congenital anatomic variant characterized by nonunion of dorsal and ventral pancreatic ducts in an otherwise fused pancreas. Of 21 patients with divisum documented by endoscopic retrograde cholangiopancreatography, 6 (28 percent) were found to have no reason other than divisum to account for multiple attacks of pancreatitis. Cholelithiasis was present in one patient, who remains free of recurrent pancreatitis after cholecystectomy only. The remaining five patients underwent surgical treatment directed at pancreas divisum in the belief that stenosis of the duct of Santorini at the entrance into the duodenum is responsible for recurrent attacks of pancreatitis. Four of five have done well with follow-up of 12, 13, 18 and 28 months. Successful sphincteroplasty of the duct of Santorini appears to prevent recurrent attacks of pancreatitis due to pancreas divisum. Pancreaticojejunostomy is reserved for those with markedly dilated ducts secondary to chronic pancreatitis.

Nonfusion of the pancreatic ducts (pancreas divisum) was diagnosed in 41 of 812 patients in whom ERCP provided a definite diagnosis (5.04% of cases). Pancreas divisum was significantly associated with diseases of the pancreas. Chronic pancreatitis was less frequently observed in cases of pancreas divisum whereas acute pancreatitis, especially acute recurrent pancreatitis, was statistically more frequently seen in patients in whom the anomaly was present. These results support the hypothesis that pancreas divisum favours the development of acute pancreatitis.

The authors relate a series concerning 123 cephalic pancreatico-duodenectomy cases for chronic pancreatitis and pancreatic tumors. Post surgical complications due to pancreatico jejunal anastomosis and those appearing later on in relation with residual parenchyma have been studied; so were described the different therapeutic proceedings remedying to them. The obstruction of Wirsung's duct in the tall of Pancreas with some acrylate glue seems interesting in limiting the post surgical complications if the risk of pancreatic fistula can be prevented while preserving the endocrine function.

Detailed clinical and laboratory follow-up was made of 113 patients, two to 12 years after their first attack of acute pancreatitis, to assess complete recovery versus the development either of acute relapsing pancreatitis, or of chronic pancreatitis. Mortality was low in patients with recurrent attacks of acute pancreatitis. Complete recovery decreased wih increasing periods of follow-up. In the group of alcoholic patients, complete recovery decreased continuously with a corresponding increase in chronic pancreatitis. In the group of patients with gallstones, chronic pancreatitis developed up to about three years after the acute attack, after which the recovery rate remained steady. Chronic pancreatitis in the patients with gallstones was usually painless. In patients with idiopathic pancreatitis, a high incidence of acute relapsing pancreatitis was seen, but this rarely persisted after three years. Pancreas function rarely recovered completely after an attack of severe acute pancreatitis. Alcohol withdrawal decreased the pain syndrome, but not the development of chronic pancreatitis. Early removal of gallstones minimized the development of chronic pancreatitis. Complete recovery did occur after one attack of acute pancreatitis, but probably only when the aetiological antecedent (alcohol or gallstones) had not been operating for a long time, as it is the antecedent rather than the acute attack which determines the eventual outcome.

The distribution and concentration of calcitonin gene-related peptide (CGRP), substance P (SP), vasoactive intestinal polypeptide (VIP), neuropeptide Y (NPY), and gastrin-releasing peptide (GRP) immunoreactivities in the pancreas of cats with experimentally induced chronic pancreatitis and of age- and sex-matched controls were investigated. By narrowing the main pancreatic duct between the head and the body to approximately 25% of its normal diameter, we induced within 5 weeks chronic pancreatitis restricted to the body and tail. In control animals, peptide immunoreactive nerves were distributed to the islets, acini, and ducts; the latter were predominantly innervated by fibers immunoreactive for NPY, VIP, or CGRP. The vasculature received an abundant supply of NPY-, CGRP-, and, to a lesser extent, SP-containing axons. Within intrapancreatic ganglia, peptide immunoreactivities were identified in fibers and ganglion cells, with the exception of CGRP and SP immunostaining, which could be visualized only in fibers. In animals with chronic pancreatitis, the innervation pattern of each peptidergic system was comparable to that described in controls. However, there was a remarkable increase in the density and staining intensity of VIP and NPY immunoreactive fibers in the exocrine parenchyma and fibrous septa of the body and tail, where chronic pancreatitis developed. Fibers immunoreactive for CGRP and SP also were moderately denser than in controls, whereas those containing GRP immunoreactivity did not show any detectable changes. In addition, a marked increase of the immunostaining for VIP and, to a much lesser extent, for NPY and GRP, was observed in neurites supplying the head of the pancreas, which appeared devoid of histologically detectable pathological alterations. Radioimmunoassay analysis confirmed the immunohistochemical observations. The increased density of distinct peptidergic nerves in the pancreas with induced chronic pancreatitis might be the result of compensatory phenomena in response to the inflammatory process.

The diagnostic value of bile salt-dependent lipase for pancreatic diseases was tested in sera of 187 patients. Of these patients, 76 suffered from pancreatic carcinoma, 43 from nonmalignant liver diseases (cirrhosis and chronic hepatitis), 18 from acute pancreatitis, and 20 from chronic pancreatitis. The remaining subjects were controls without pancreatic pathology. Bile salt-dependent lipase was determined by a sandwich enzyme-linked immunosorbent assay using polyclonal antibodies. Amylase and CA 19-9 antigen were also determined. In sera from control patients, the mean level of bile salt-dependent lipase was 1.5 micrograms/L. This level is quite similar to that of patients with benign liver diseases (1.1 micrograms/L) and with chronic pancreatitis (1.4 micrograms/L), but it was raised to 3.5 micrograms/L in patients with acute pancreatitis and decreased to 0.5 microgram/L in subjects with pancreatic adenocarcinoma. Thirty percent of control subjects and 73% of cancer patients had a bile salt-dependent lipase serum level below the cutoff value of 0.5 microgram/L. In acute pancreatitis, 11 of 16 subjects had levels above 1.5 micrograms/L. Amylase level largely increased in acute pancreatitis but was normal in all other groups. Concerning CA 19-9 antigen, 65% of control patients and > 80% of patients with nonmalignant pancreatic or liver diseases had normal levels. In sera from cancer patients, 80% presented with high levels. Accordingly, 36 of 38 patients with pancreatic cancer had either low serum levels of bile salt-dependent lipase (< 0.5 microgram/L) or high values of CA 19-9 antigen (> 37 U/ml; sensitivity 95%).(ABSTRACT TRUNCATED AT 250 WORDS)

Pancreas divisum has been claimed to be a harmless congenital variant or to occasionally cause acute relapsing pancreatitis (ARP), chronic pancreatitis (CP), or a chronic abdominal pain (CAP) syndrome. Both surgical and endoscopic approaches to accessory papilla decompression have been promulgated and widely disparate results reported in the literature. We retrospectively reviewed a five-year experience with dorsal pancreatic duct decompression at our institution utilizing a variety of endotherapeutic techniques. Data collected included procedural complications; patient interpretation of pre- and posttherapy pain, frequency, and intensity graded on an analog pain scale; frequency of hospitalization; and patient perception of "global" improvement to endotherapy. At a mean follow-up of 20 months, there was a statistically significant decrease in pancreatitis incidence in 15 patients with ARP (P = 0.016) and 19 patients with CP (P = 0.025). The frequency and intensity of chronic pain was also significantly improved (P < 0.001) in the latter group. In contrast, only one of five patients with CAP and normal dorsal pancreatography and secretin tests experienced global improvement, and there was no improvement utilizing an analog pain scale (P = 0.262) in the group as a whole. There was a 20% incidence of mild procedure or subsequent stent-related pancreatitis and an 11.5% accessory papilla restenosis rate. It is concluded that a subset of carefully selected patients with pancreas divisum may respond to endotherapy but that long-term follow-up will be required to define its ultimate place in the management of symptomatic patients with this anomaly.

Human pancreas-specific protein (PASP) has been characterized previously as a serum marker for pancreatitis. It was then identified as pancreatic procarboxypeptidase B (PCB). The aim of the present study was to verify the usefulness of PASP (PCB) as a serum marker in patients with acute (n = 20) and chronic (n = 12) pancreatitis and in those following endoscopic retrograde cholangiopancreaticography (ERCP) (n = 44). Serum PASP values were analyzed by radioimmunoassay, with a range of normal values between 15 and 111 ng/ml. Between April 1992 and September 1992, 20 subjects (19-86 years of age) with acute pancreatitis (alcoholic, 8; biliary, 8; other, 4) were studied. We found edematous pancreatitis in 17 cases and severe hemorrhagic pancreatitis in three cases. At admission, peak levels of PASP (average value, 1,976 +/- 329 ng/ml), pancreatic isoamylase (942 +/- 151 U/L) and lipase (2,946 +/- 534 U/L) were detected in 15 of 20, 16 of 20, and 12 of 20 cases, respectively. The etiology of the pancreatitis had no influence on the PASP values. Furthermore, 10 patients with alcoholic and two patients with nonalcoholic chronic pancreatitis (29-67 years of age) were studied. The average peak level of PASP was 1,229 +/- 434 ng/ml. In this group, PASP paralleled the time course of amylase and lipase. Maximal PASP, amylase, and lipase levels were found in 11 of 12, nine of 12, and five of 12 patients, respectively, on the day of admission. ERCP was performed in 44 patients (36-87 years of age), demonstrating common bile duct stones in 16 and bile or pancreatic ductal tumors in 15 cases.(ABSTRACT TRUNCATED AT 250 WORDS)

This study compared diet, type of alcoholism, and smoking in three groups of alcoholic men, with chronic pancreatitis (n = 56), with histological cirrhosis (n = 50), and without pancreatitis or cirrhosis (controls; n = 50) by a multidimensional analysis. Only patients in whom the first symptom of pancreatitis or cirrhosis was present for < 1 year before the interview were included. Patients with pancreatitis consumed more nonalcohol calories than cirrhotics (p < 0.05). The percentage of calories taken as proteins (p < 0.0003) and lipids (p < 0.0001) was higher and the percentage of calories taken as alcohol (p < 0.0003) was lower in patients with pancreatitis than in cirrhotics and control patients. There was no difference among the three groups for total calories/basal energy expenditure ratio, total nonalcohol calories/basal energy expenditure ratio, mineral and vitamin intake, or tobacco consumption. The duration of excessive alcohol consumption and the total alcohol consumption in patients with pancreatitis was similar to that of controls but lower than that of cirrhotics (p < 0.002 and p < 0.05, respectively). Three parameters were found to be independently different in the three groups by discriminant analysis: percentage of calories taken as lipids (p < 0.0001), duration of excessive alcohol consumption (p < 0.002), and percentage of calories taken as proteins (p < 0.08). These three parameters explained 24% of the variance. We conclude that the reasons alcoholic men develop chronic pancreatitis may be explained partly by dietary habits.(ABSTRACT TRUNCATED AT 250 WORDS)
