The term "postcholecystectomy syndrome" indicates etiologically and pathogenetically various lesions of the organism related to variably expressed symptoms of pain and dyspepsia. The author has performed endoscopic retrograde cholangiopancreatography (ERCP) to 60 patients with "postcholecystectomy syndrome" to find out what underlies this syndrome. In 34 (56%) of the patients the biliary ducts were dilated. The most frequent cause of this was Vater's papilla stenosis, which was found in 26 patients (43%). The author is of the opinion that this stenosis preceded the cholecystectomy and was the result of inflammatory processes related to cholelithiasis. In 20 patients stones were found in the biliary ducts, single or multiple. In most cases the stones in the biliary duct had been missed during the cholecystectomy. In some patients the stones in the biliary duct were formed after the operation. In 26.6% of the patients ERCP helped in discovering other diseases such as chronic pancreatitis, duodenal ulcer and peripapillary diverticulum which are in the basis of the "postcholecystectomy syndrome". The author recommends to every patients with persistent complaints after cholecystectomy ERCP to be performed in order to find out the cause of the complaints and determine the correct treatment--medicamentous or surgical.

We have investigated the relationship between cholecystokinin levels and abdominal pain in patients with chronic pancreatitis. The baseline and postprandial cholecystokinin levels were measured in 15 patients with chronic pancreatitis (8 with and 7 without abdominal pain) and in a reference group of 8 healthy subjects. The baseline, 30 and 60 min postprandial plasma cholecystokinin levels were significantly (p less than 0.05) higher in the patients with pain as compared with the other two groups. No correlation was observed between increased cholecystokinin levels and impairment of the exocrine pancreatic function as assessed by the NBT-PABA test. The increased cholecystokinin levels might be an important factor in the genesis of pain in chronic pancreatitis.

This randomized double-blind trial examined the influence of the radical scavengers allopurinol (50 mg per rectum, four times per day) and dimethyl sulfoxide (500 mg per rectum, four times per day) on pancreatic pain treated with intramuscular pethidine hydrochloride (100 mg followed by 50 mg every 4 hours until complete pain relief) in patients given nothing orally and intravenously hydrated. Addition of allopurinol or dimethyl sulfoxide to the analgesic regimen significantly enhanced its efficacy, enabling at least 57% (13 patients receiving allopurinol and 12 patients receiving dimethyl sulfoxide) of 43 patients to be free of pain within 12 hours after admission compared with only four (17%) of 23 controls achieving the same effect. This advantage extended to all patients within 24 hours after admission, leaving 11 controls (48%) still in pain. Consequently, all patients given allopurinol or dimethyl sulfoxide were discharged 3 days after admission, a result realized in only five (22%) of the assessable controls who were discharged after 5 days of hospitalization. The results suggest that oxygen-derived free radicals are implicated in the mechanism of abdominal pain caused by alcohol-induced chronic pancreatitis and that removing them results in a beneficial therapeutic effect.

Pancreatic secretion is involved in circadian regulation of the whole organism. This observation was obtained in animals and humans with pancreatic fistulas. We report on three patients in whom the pancreas was removed totally or subtotally because of chronic pancreatitis with severe pain. A segment of the removed gland was transplanted into the thigh in order to preserve endocrine function. The pancreatic duct was drained by a polyethylene tube until pancreatic duct occlusion. Postoperatively juice volume increased within 3 days and remained constant afterwards with 300 ml in 24 hours. Secretin, cholecystokinin and food intake are able to stimulate the transplanted segment in a typical manner. The secretion showed circadian changes. In all patients the pancreatic juice content of protein, amylase, trypsinogen, calcium, and zink decreased till 11 p.m. After 11 p.m. the content of all substances increased and reached maximal values at 6 a.m. Flow rates and therefore output per minute decreased greatly till 6 a.m. The large juice volume of 300 ml in 24 hours is perhaps the consequence of a break down of the feedback mechanism between intraduodenal trypsin activity and CCK-release. The changes during the night may be of pathogenetic relevance. In the early morning pancreatic juice is highly concentrated and the flow rate is very low. High protein concentrations, high calcium concentrations, and reduced flow rates may lead to protein and calcium carbonate precipitates. This mechanism is under discussion in the pathogenesis of chronic pancreatitis.

In an effort to minimize the nutritional complications that follow resection of the pancreas for severe chronic pancreatitis, the authors have performed a duodenum-preserving total pancreatectomy in eight patients for severe unremitting pain requiring large doses of opiate analgesia. Good relief of pain was obtained in six patients (75%), in whom the quality of life was undoubtedly improved. There were no problems with the control of diabetes after this procedure in any of these patients, and no patient has suffered any hypoglycemic attacks requiring medical treatment. This improved control of the diabetic state is probably related to a more physiologic state of the upper digestive tract, enabling a normal food intake. The authors found the operation to be technically difficult, however, and although there were no post-operative deaths, major complications were encountered in four patients. These consisted of postoperative bleeding requiring reoperation (two patients), sepsis, and a duodenal fistula, which progressed to stenosis.

To assess the contribution of parenchymal hypertension to pain, pancreatic tissue pressures were measured intraoperatively in 17 patients with chronic pancreatitis and in four other patients undergoing pancreatic surgery (reference group). The technique involved direct fine needle cannulation of the pancreas using a flow infusion system, which measured parenchymal resistance to this infusion. Three to six recordings were obtained at each site. In chronic pancreatitis the pressure (mean +/- s.e.m.) was substantially elevated in all regions of the pancreas compared with reference subjects: head (257 +/- 59 versus 19 +/- 5 mmHg, P less than 0.05); body (201 +/- 51 versus 13 +/- 6 mmHg, P less than 0.05) and tail (161 +/- 45 versus 11 +/- 3 mmHg, P less than 0.05). Elevation was greater in areas of calcific disease (281-383 mmHg) than in non-calcific disease (81-120 mmHg, P less than 0.05). Mean pancreatic ductal pressure in 10 patients (seven with calcific disease) was 20 +/- 4 mmHg. Differential pressure measurements within the pancreas helped determine the extent of resection in six patients with diffuse disease. The greatly increased tissue pressures in chronic pancreatitis, especially in the presence of calcification, suggest a possible 'compartment syndrome'.

The papilla of Vater and its sphincter of Oddi, lying at the confluence of the bile and pancreatic ducts in man, have long been suspected as a source of upper abdominal pain. Enlarging the opening of the transpapillary segment of the bile and major pancreatic ducts by using a transduodenal sphincteroplasty with transampullary septectomy resulted in death in a patient with a peripapillary diverticulum and pancreas divisum. Eight-six patients followed for 1 to 10 years experienced a 75% success rate. Thirty-six patients had a marked stenosis of their duct of Wirsung, suggesting that their pain was primarily from the pancreas. The remainder had either a generalized narrowing (40 patients) or a normal (7 patients) papilla. Pain was not satisfactorily resolved in patients with an associated pancreas divisum, chronic pancreatitis, and recurrent episodes of acute pancreatitis with alcoholism.

Traumatic pseudoaneurysm of the abdominal aorta has been infrequently reported in the literature. We report a case of an infected pseudoaneurysm of the supraceliac aorta which we believe to be secondary to celiac plexus block performed for pain from chronic pancreatitis. The aneurysm was successfully repaired using a Dacron graft through a thoracoabdominal approach. The possible mechanism of aortic injury from celiac plexus block is discussed.

The aim of this study was to analyze the evolution of surgical indications in alcoholic chronic pancreatitis (ACP) and to compare long term results after medical (n = 72) and surgical (n = 150) treatment with or without pancreatic resection. Since 1968, a retrospective study was carried out on 222 consecutive male patient. 68% of them, were operated on for unrelieved pain or complications at a mean of 5 years after the onset of the symptom. The mean follow-up was 10 years. The study of evolution of the indications and results of surgical treatment was made on two consecutive ten-year periods and showed that 68% of pancreaticoduodenectomies and 55% of distal pancreatectomies (DP) were performed during the first period. Indications for primary pancreaticoduodenectomy did not decrease since 1980, while those of distal pancreatectomy (DP) changed (no DP for acute pancreatic effusion with fistula before 1980, no DP for unrelieved pain after 1980). Ten patients underwent operative drainage of pseudocysts before 1980 versus 21 after 1980 (13% vs 29%) with no operative death. Twenty patients underwent biliary and/or intestinal and/or ductal drainage during the first period versus 22 during the second (25% vs 30%). The overall 12-year actuarial survival between operated and non operated patients was no significantly different (respectively 72% +/- 10% and 64% +/- 12%). The actuarial 10-year survival rate was significantly better after DP (73% versus 53% after drainage and 28% after pancreaticoduodenectomy). No patients underwent specific pancreatic reoperation after pancreaticoduodenectomy versus 25% after DP.(ABSTRACT TRUNCATED AT 250 WORDS)

The aim of this study was to determine the prevalence of diminished mean tryptic activity (MTA) in duodenal juice of patients with nonulcer dyspepsia following injection of a Lundh test meal. Two separate studies were undertaken. The first examined a consecutive group of 100 patients with suspected pancreatic disease referred over a period of 2 yr. In these patients, receiver-operating-characteristic analysis was used to determine the point of best discrimination, which occurred at 7 microEq/mL/min when non-pancreatic disease patients were compared with those with chronic pancreatitis or pancreatic cancer. The second study involved 22 patients with endoscopically confirmed nonulcer dyspepsia. The MTA for the patients with unexplained dyspepsia did not differ from 17 healthy controls, but a further 16 pancreatic disease control patients had significantly decreased values (p less than 0.01). Six patients with unexplained dyspepsia (27%) had an MTA of 7 microEq/min/mL or less, indicating impaired pancreatic function, which was more frequent than in healthy controls (p = 0.02). These six patients had significantly different symptoms, being more likely to have pain radiating through to the back (p = 0.017) and pain waking them from sleep (p = 0.002), and less likely to have postprandial pain (p = 0.045). It was of interest that the alcohol intake was not greater in these six patients. It is concluded that pancreatic disease may explain the symptoms of some patients with nonulcer dyspepsia.
