In a follow-up-series on 37 patients, who had been operated on for pancreatitis, the effect of pancreas insufficiency on the well-being of resected and non-resected patients was examined. Analyses of fatcontent in feces, collected over a three day-period, revealed that all patients with chronic pancreatitis now had a maldigestion, in particular patients with duodenopancreatectomie. Pseudocyst-patients showed no maldigestion. Increased in the bodyweight in most cases could not only be explained by drug-substituion of encymes but was also due to the resection of the pain-producing area of the pancreas.

The authors report 9 cases of painless chronic pancreatitis and review the literature on this apparently rare condition. They emphasise the contrast between absent or minimal pain and the severe pathological lesions. In the light of these cases and pathological specimens, they attempt to interpret the pain during chronic pancreatitis. Pain seems to occur when there is a downhill course.

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.

Studies were undertaken in 40 patients with chronic pancreatitis six months to seven and a half years (mean 25 months) after operation, results being compared with pre-operative findings. Measurements included: exercise capacity, absence of pain, body weight, endocrine (36) and exocrine (25) pancreatic function. Almost all patients returned to full or only slightly impaired activity, were free of pain or had less pain and weight increase. Exocrine pancreatic function (secretin-pancreozymin test and faecal fat) was noted in 11 of 25 patients. In another 11 pre-operative progression was arrested. But endocrine function improved in only three of 36 and worsened in 13 (manifestation of subclinical diabetes in eight, worse glucose tolerance in five). The results justify a more active surgical approach in the treatment of chronic pancreatitis in order to save the patients from an often long and painful "burning out" of the disease on purely conservative treatment. Furthermore, exocrine pancreatic function, at least, is maintained or improved.

A total of sixty-one operations were performed in sixty of seventy-one patients with chronic pancreatitis, with the following results. 1. The procedures used were side to side pancreaticojejunostomy in twenty-four patients, caudal pancreatectomy in ten, pancreaticoduodenectomy in six, total pancreatectomy in one, removal of pancreatic calculi in four, cystojejunostomy in two, biliary tract procedures in twelve, and drainage of pancreatic abscess in one. Operative fatality occurred in six patients, with fifty-four surviving operation. 2. Of fifty-three patients surviving operation (excluding the one who underwent only exploratory laparotomy), forty-seven (88 per cent) had relief of pain. With the exception of two patients with complicating cancer of the pancreas at the time of operation, of fifty-two patients surviving operation, thirty-nine (75 per cent) had satisfactory results at follow-up study. 3. Sixteen of twenty-four patients (66.7 per cent) undergoing side to side pancreaticojejunostomy had satisfactory follow-up results. 4. Comparison of pre- and postoperative body weight levels in twenty-one patients undergoing side to side pancreaticojejunostomy showed a postoperative loss of less than 10 per cent in seven, unchanged weight in two, and a gain in eleven patients, including five with more than 10 per cent gain. However, fat absorption examination in these patients showed no distinct postoperative improvement in digestion and absorption. 5. Histologic evidence in one patient at autopsy four years and eleven months after side to side pancreaticojejunostomy indicated improvement in fibrosis of the pancreas as compared with the findings at operation.

Jaundice occurring in patients with pancreatitis is usually due to hepatocellular injury or to associated biliary tract disease. Common duct obstruction is occasionally caused by pancreatic fibrosis, edema or pseudocyst in patients who have neither hepatocellular injury nor biliary tract disease. We have studied 7 patients with obstructive jaundice due to pancreatitis who demonstrated no other known cause for jaundice. The difficulty in making the differential diagnosis between benign and malignant disease in these patients, particularly when no pain is associated with obstructive jaundice, is discussed. In view of the fact that the terminal common duct traverses the pancreas, it is uncertain why obstructive jaundice associated with chronic pancreatitis does not occur more often unless the condition is sometimes transient and overlooked. Operative intervention is required in those patients in whom jaundice is persistent. Operation is intended to decompress the biliary tract and the pancreas. The approach used will be dictated by the operative findings in each patient.

The value of endoscopic retrograde cholangiopancreaticography (ERCP) for establishing the indication for surgery and for planning surgical procedures is discussed. The two most widely practiced methods of direct cholangiography - percutaneous transhepatic and endoscopic retrograde cholangiography (PTC and ERC) - are compared: although the filling rate with ERC is slightly lower than with PTC, the endoscopic method has some important advantages as it allows endoscopic observation and biopsy of the duodenum. Furthermore, opacification of the pancreatic duct system often provides important additional information. ERCP is essentially important in post-cholecystectomy syndrome, as puncture of undilated bile ducts is difficult and persistent symptoms after cholecystectomy are not infrequently related to pancreatic disease. The importance of rapid surgical intervention after retrograde filling of the biliary tree in obstructive jaundice is stressed. In pancreatic diseases the indication for surgery is based mainly on clinical and laboratory findings. Differentiation of malignant and inflammatory changes in the pancreaticogram is still a problem. However, the contribution of ERCP to pancreatic surgery is very important, as it exactly localized lesions of the pancreas and therefore allows detailed planning of a surgical procedure. Stenosing or obstructing lesions often are an indication for surgery, even if their malignant nature is not certain, as severe pain in chronic pancreatitis may be relieved by surgery. The potential for therapeutic application of endoscopy in biliary and pancreatic diseases is briefly discussed.

X-rays of the pancreatic duct can now be obtained by a nonoperative endoscopic approach (endoscopic retrograde cholangiopancreatography-ERCP). After more than 2 years experience we have found that the pancreatic duct can be visualized in 85 to 90% of patients. This test is used to detect pancreatic carcinoma in the symptomatic patient and in searching for an operative pancreatic lesion in a patient with known recurrent or chronic pancreatitis. Many of these patients have pain or a transiently elevated amylase; a few have steatorrhea or abnormalities of the duodenal sweep on barium meal. Stenosis or obstruction of the main pancreatic duct with or without proximal duct dilation are the characteristic abnormalities noted in pancreatic carcinoma. A rare pancreatic tumor which is not in juxtaposition with the duct will have a normal pancreatogram although the common duct may be obstructed by cholangiography as it passes through the head of the pancreas. In patients with chronic pancreatitis it may be difficult to differentiate an inflammatory from a neoplastic stricture by either operative or endoscopic pancreatography. In the future, cytologic and biochemical examination of the pancreatic secretions obtained at ERCP may increase the accuracy of diagnosing carcinoma.

According to the theory of negative feedback regulation of pancreatic enzyme secretion by proteases, treatment with pancreatic extracts has been proposed to lower pain in chronic pancreatitis by decreasing pancreatic duct pressure. We conducted a prospective placebo-controlled double blind multicenter study to investigate the effect of porcine pancreatic extracts on pain in chronic pancreatitis. 47 patients with pain (41 males, 6 females) due to chronic pancreatitis documented by sonography, endoscopic retrograde cholangiopancreatography, and CT were included. Exclusion criteria were steatorrhea above 30 g/day, gastric or pancreatic resections in the history, and serum bilirubin above 1.5 mg/dl. Patients received pancreatic extracts (acid-protected microtablets; Panzytrat -20,000; 5 x 2 capsules/day; proteases/capsule 1,000 Pharmacopoea europaea units) for 14 days followed by treatment with placebo for another 14 days or vice versa. Pain (graded from 0 to 3) and concomitant use of analgesics (N-butylscopolaminiumbromide and tramadol) were recorded by diary. Physical examination and blood chemistry were done at day -1, 15 and 29. Quantitative stool fat was determined at days -2/-1, 13/14 and 27/28. 43 patients completed the studies. Pain improved in most patients irrespective of whether they started with placebo or verum. There was no significant difference between both treatment arms. We conclude that pancreatic extracts are not very efficient in lowering pain.

Two male patients with complications associated with chronic pancreatitis are described. In each patient, preoperative examinations revealed a large stone obstructing the main duct in the head of the pancreas. Lateral pancreaticojejunostomy was performed to relieve pain and prevent further attacks of pancreatitis. During each operation, the stone was fragmented under direct visual control with the use of a flexible choledochoscope and a contact electrohydraulic lithotriptor. The stone was removed and ductal flow through the head of the pancreas was reestablished. Our experience shows that endoscopic electrohydraulic lithotripsy facilitates operative removal of pancreatic stones deeply located in the head of the pancreas.
