In the beginning of this century the "early operation" in acute pancreatitis was widely used. The irreversibility of the local necrosis and the failure of conservative treatment again lead to the application of this procedure. Early operation is indicated when the pancreatitis shows a more severe degree and when there is no success on conservative therapy or even deterioration in the patient's condition. Early operation means digital removal of the necrosis and/or resection of the pancreas, procedures on the biliary tract, methods for suppression of the secretory activity and installation of jejunal fistulas for external feeding. The mortality rate of partial necrotizing pancreatitis was lowered by this means. In case of total necrosis the mortality was still about 100%. In the postacute stage complications such as sequestration, abscess formation, sepsis, hemorrhage, fistulas can arise. In some of these complications only a "delayed operation" is successful. If a biliary acute pancreatitis was not early and definitively treated, the causative diseases of the biliary tract have to be cured in the postacute stage.

Clinical characteristics of 46 cases of acute pancreatitis treated with total parenteral nutrition were examined. Hyperalimentation may be used in these severely ill patients with minimal technical or metabolic morbidity. This method of nutritional support can maintain patients with nonfunctional gastrointestinal tracts for several months. Catheter-related sepsis was more common than expected early in the course of acute pancreatitis but caused minimal morbidity. The incidence of catheter-related sepsis late in disease was minor. Hyperalimentation had little if any effect on the pathophysiology of acute pancreatitis as judged by the overall mortality and the incidence and severity of the complications of acute respiratory failure and acute renal failure. It is not clear that parenteral hyperalimentation alters the course of acute pancreatitis but it is a useful adjunct for nutritional support in this illness.

Clinical and pathological information from forty patients who died with pathologically severe acute pancreatitis was correlated. Patients were classified into four etiologic groups: those with biliary pancreatitis (11 patients), alcoholic pancreatitis (13 patients), idiopathic pancreatitis (10 patients), and renal failure (6 patients). Antemortem diagnosis was made in only 57 per cent of the patients studied. The diagnosis was determined before death in 91 per cent of the biliary patients but in none of the renal patients. Thirty-seven patients died from their first clinical attack of pancreatitis. Operation in patients with biliary pancreatitis failed when biliary decompression was not provided. Peripancreatic sepsis was a frequent lethal mechanism in patients with biliary pancreatitis, but renal and respiratory failure were more common in patients with alcoholic pancreatitis.

Pancreatic necrosis is a principal determinant of the severity, duration, and infectious complications of acute pancreatitis. There has been no objective index for pancreatic necrosis, and its recognition has necessarily rested upon nonspecific clinical signs, including later deterioration or appearance of sepsis. In search of such an index, we have measured serum levels of a poly-[C]-specific acid ribonuclease (RNase) in 38 patients with acute pancreatitis, 12 patients with chronic pancreatitis, and 50 control patients. The values in chronic pancreatitis (mean, 52 units; range, 33 to 80 units) were within observed normal limits (mean, 51; range, 17 to 94). The values in acute pancreatitis segregated into two groups, normal values (group A) and high values (group B). Of 25 patients in group A (mean, 46; range, 19 to 87), only one developed evidence of pancreatic necrosis or abscess. In contrast, of the 13 patients in group B (mean, 192, range, 98 to 385), 11 required surgical debridement/drainage for pancreatic necrosis (six) or abscess (five) (P less than 0.001). Each of the other two patients had prolonged pancreatic inflammation with fever and a pancreatic mass which persisted for more than 2 weeks. RNase levels in group B patients rose within a few days after onset of pancreatitis and tended to parallel the clinical course. These findings suggest that measurement of serum RNase in acute pancreatitis gives a reliable indication of pancreatic necrosis. Therefore RNase determinations should be of value for earlier identification and monitoring of patients at high risk of late complications, and for helping to select those who will benefit from early debridement before secondary infection occurs.

Acute pancreatitis is discussed from the viewpoint of a medical intensive care unit, with particular reference to the early and late complications. The measures which must be promptly implemented in order to successfully combat the grave early complications of shock and acute renal failure are stressed. Continuous monitoring ensures that prompt surgical management is undertaken in cases of late complications-abscess formation, sequestration and sepsis. A review of the characteristic clinical and laboratory data of patients with acute pancreatitis treated in our unit is presented in table I.

This is a report of our experience with 13 patients who had a distal common duct stricture associated with chronic relapsing pancreatitis. All patients, when first seen, had an elevated alkaline phosphatase level; eight of 13 patients also had an elevated serum bilirubin level. Five of the jaundiced patients had a febrile course; a preoperative diagnosis of acute cholangitis was made in four of these. Eight of the 13 patients have had a choledochoduodenostomy for relief of biliary obstruction; seven of these patients are living and well; one died of continued alcoholism and pancreatitis. One patient had a loop cholecystojejunostomy; decompression was inadequate and death due to septicemia secondary to ascending cholangitis ensued. Four patients have not yet had an operation. Two are symptomatic, but elective operation has been refused. Two have been lost to follow-up. We recommend investigation of the biliary tract in patients known to have chronic relapsing pancreatitis who also have persisting abdominal symptoms and an elevated alkaline phosphatase. If a stricture of the distal common bile duct is identified in the absence of acute pancreatitis, choledochoduodenostomy should be performed.

Of 92 patients with moderately severe acute pancreatitis initially studied within three weeks of onset by ultrasonic tomography, 52 developed an acute fluid collection in the lesser sac. Documentation of the ultrasound prediction of pseudocyst was achieved by surgery or autopsy in 26 cases. Spontaneous resolution of the acute pseudocyst was demonstrated by serial ultrasonography and radiogrphy in another 10 patients. Exploration exposed 3 false positive predictions of pseudocyst. Eleven other patients with a cystic configuration either refused surgery or were lost to followup. Acute pseudocyst formation is a relatively common phenomenon in the early phases of moderately severe pancreatitis. While spontaneous resolution of acute pseudocysts is frequent, in approximately 50% of cases acute pseudocysts progress to chronic pseudocysts. A distinction between acute and chronic pseudocyst is necessary since specific surgical management depends upon the phase of pseudocyst development. Unless regional sepsis supervens, acute pseudocyts of less than three weeks' duration may be followed by serial ultrasonography in the hope of spontaneous resolution. When a pseudocyst has achieved chronic status, spontaneous resolution is rare. Persistent conservative management under these conditions invites the excessive mortality and morbidity of spontaneous rupture.

Intestinal fistulization following acute pancreatitis is a complication of abscess formation and may occur after initial surgical drainage. It should be suspected in anyone with protracted pancreatitis in whom an abdominal mass suddenly disappears or in whom gastrointestinal bleeding develops. Although transient improvement may occur, decompression will often be incomplete and will usually be followed by recurrent sepsis or severe life threatening hemorrhage. For this reason, spontaneous fistulization into the intestine does not eliminate the need for adequate surgical drainage. With fistulas into the colon, drainage should be combined with proximal diverting colostomy. Some duodenal fistulas may respond to abscess drainage and intravenously administered hyperalimentation, while others may require drainage plus conversion from a side to an end fistula.

Pancreatic abscess is probably the most serious complication of acute pancreatitis. During the ten-year period from 1966 to 1975, twenty-eight patients with pancreatic abscess following acute pancreatitis were treated by surgical drainage. A review of these cases revealed that there was a lull in the clinical course of the antecedent pancreatitis prior to the time of surgical drainage in 70% of the cases. Despite an aggressive surgical approach, there were major postoperative problems in 26 patients. Sepsis persisted in 14 patients. Major gastrointestinal hemorrhage occurred in seven, intra-abdominal bleeding in nine, and fistulization in 13. Fourteen patients died (a mortality of 50%). The operative treatment of pancreatic abscess must be aggressive and persistent. In addition to extensive drainage with soft sump drains, vigilance must be exercised to avoid pressure against bowel or major vessels. Reoperation should be considered if postoperative improvement is not sustained.

Furosemide frequently is advocated as a prophylaxis against renal failure in septic and injured patients; this effect is thought to be secondary to an increase in renal blood flow. This postulate was tested within 72 hours of admission in 22 previously healthy patients with acute pancreatitis (two), massive trauma (ten), or severe sepsis (ten). Renal clearances of inulin (GFR), para-amino hippurate (ERPF), sodium (CNA), osmoles (COsm), and free water (CH2O) were measured in milliliters per minute before and after the intravenous infusion of furosemide (0.5 mg. per kilogram of body weight). Renal vein PAH levels (EPAH) in eight patients were used to calculate true renal plasma flow (TRPF), true renal blood flow (TRBF), and renal vascular resistance (RVR). Furosemide caused a significant increase in urine volume, CNa, and COsm; there were no significant changes in GFR, ERPF, RVR, TRBF, and EPAH. These findings also were observed when the patients were subgrouped according to elevated, normal, or low renal plasma flow and elevated renal vascular resistance. No significant changes were seen in EPAH, thus making a redistribution of renal blood flow unlikely. These studies indicate that furosemide has only a diuretic effect and no hemodynamic effect in the kidney; it has the potential of seriously reducing the circulatory volume and causing renal failure in critical patients.
