History

For most patients with chronic pancreatitis, abdominal pain is the presenting symptom. Either the patient's age or the etiology of the disease has some influence on the frequency of this presentation. Ninety-six percent of those with early onset idiopathic pancreatitis present with abdominal pain, compared with 77% with alcohol-induced disease and 54% with late-onset idiopathic chronic pancreatitis.

Clinically, the patient experiences intermittent attacks of severe pain, often in the midabdomen or left upper abdomen and occasionally radiating in a bandlike fashion or localized to the midback. The pain may occur either after meals or independently of meals, but it is not fleeting or transient and tends to last at least several hours. Unfortunately, patients often are symptomatic for years before the diagnosis is established; the average time from the onset of symptoms until a diagnosis of chronic pancreatitis is 62 months. The delay in diagnosis is even longer in people without alcoholism, in whom the average time is 81 months from onset of symptoms to diagnosis.

The natural history of pain in chronic pancreatitis is highly variable. Most patients experience intermittent attacks of pain at unpredictable intervals, while a minority of patients experience chronic pain. In most patients, pain severity either decreases or resolves over 5-25 years. Nevertheless, ignoring pain relief with the expectation that the disease eventually will resolve itself is inappropriate. In alcohol-induced disease, eventual cessation of alcohol intake may reduce the severity of pain. Variability in the pain pattern contributes to the delay in diagnosis and makes determining the effect of any therapeutic intervention difficult.

Other symptoms associated with chronic pancreatitis include diarrhea and weight loss. This may be due either to fear of eating (eg, postprandial exacerbation of pain) or due to pancreatic exocrine insufficiency and steatorrhea.

Physical Examination

In most instances, the standard physical examination does not help to establish a diagnosis of chronic pancreatitis; however, a few points are noteworthy.

During an attack, patients may assume a characteristic position in an attempt to relieve their abdominal pain (eg, lying on the left side, flexing the spine and drawing the knees up toward the chest).

Occasionally, a tender fullness or mass may be palpated in the epigastrium, suggesting the presence of a pseudocyst or an inflammatory mass in the abdomen. Patients with advanced disease (ie, patients with steatorrhea) exhibit decreased subcutaneous fat, temporal wasting, sunken supraclavicular fossa, and other physical signs of malnutrition.

This endoscopic retrograde cholangiopancreatography (ERCP) shows advanced chronic pancreatitis. The pancreatogram has blunting of the lateral branches, dilation of the main pancreatic duct, and filling defects consistent with pancreatolithiasis. The cholangiogram also shows a stenosis of the distal bile duct and a dilated biliary tree.

Chronic pancreatitis. Abdominal CT scan showing that a pancreatic pseudocyst is responsible for the distortion of the ductal system.

This patient has recurrent abdominal pain. She used alcohol heavily in the past and was involved in a motor vehicle accident. The pancreatogram shows subtle blunting of side branches consistent with chronic pancreatitis. A stricture also is present in the body of the pancreas where it drapes over the spine, probably resulting from the trauma she sustained in the motor vehicle accident. Air in the stomach makes it difficult to observe that contrast is filling a pseudocyst on the other side of the stricture. These findings are not amenable to endoscopic intervention, and the patient was sent for a distal pancreatectomy.

Chronic pancreatitis. This magnetic resonance cholangiopancreatography (MRCP) shows a healthy biliary system. The pancreatic ductal system is not well visualized. A subsequent endoscopic retrograde cholangiopancreatography (ERCP [not pictured]) showed pancreas divisum, with no evidence of a communication with the pseudocyst. The endoscopic features were ideal for an endoscopic transgastric pseudocystogastrostomy.

Chronic pancreatitis. CT scans of the abdomen following an endoscopic transgastric pseudocystogastrostomy. Note that 2 stents are placed through the stomach and into the pseudocyst. Before undertaking this type of endoscopic intervention, the endoscopist must be confident that a cystadenoma has not been mistaken for a pseudocyst.

Chronic pancreatitis. This patient had a persistent postoperative leak from the site of a distal pancreatectomy. In the mid-1990s, the author sought to facilitate enteric drainage using transpapillary stents placed into the pancreatic duct. While this changed the fluid dynamics in favor of healing the disrupted duct, some patients developed complications from this technique.

Chronic pancreatitis. The persistent postoperative leak from the site of a distal pancreatectomy has healed at 1-month follow-up (see the image above). However, after 4 weeks of transpapillary stenting, the pancreatogram now shows a stent-induced stenosis near the surgical genu (arrow). Based on this experience, the author stopped using pancreatic stents in this setting.

Chronic pancreatitis. This patient developed abdominal pain several weeks after being accidentally hit with a baseball bat. A CT scan showed a large splenic hematoma, and the patient underwent a splenectomy. His postoperative course was notable for recurrent pain, abdominal distension, and elevation of amylase levels over the course of 2-3 months. This repeat CT scan shows postsurgical changes in the left upper quadrant and a large fluid collection.

Chronic pancreatitis. The pancreatogram shows a small leak from the tail of the gland.

Chronic pancreatitis. A nasopancreatic tube courses through the esophagus, stomach, and duodenum and into the pancreatic duct. Externally, the end of the tube is attached to a suction bulb to decompress the ductal system and monitor its function on a daily basis. In contrast to patients treated with transpapillary stents, none of these patients ever has failed to return for a follow-up appointment. In addition, while stent obstruction and subsequent infection can occur with transpapillary stents, the author has not observed this complication while using nasopancreatic tubes.

Chronic pancreatitis. Nine days after placement of a nasopancreatic tube, a pancreatogram obtained via the tube showed that the disruption had healed (see the above image). The tube then was removed.

Chronic pancreatitis. This follow-up CT scan (see the above 2 images) shows a percutaneous tube in the left upper quadrant that was used to drain a fluid collection. It was removed after 4 weeks. The patient returned to work, regained his weight, and had no recurrence of abdominal pain or signs of a recurrent pancreatic leak.

Chronic pancreatitis. Pancreatogram in a patient with a pancreatic pseudocyst. Note how the pancreatic ducts are extrinsically distorted by a mass lesion.

This pancreatogram shows a pseudocyst communicating with the main pancreatic duct in a patient with chronic pancreatitis and recurrent abdominal pain. He was treated endoscopically with a transpapillary stent placed into the pancreatic duct.

Four weeks after placement of a transpapillary stent, a patient with a pseudocyst communicating with the main pancreatic duct (chronic pancreatitis with recurrent abdominal pain) had not had a recurrence of pain. The CT scan showed resolution of the cyst, and the follow-up pancreatogram showed marked improvement. Transpapillary stenting of the pancreatic duct should be reserved for patients with established chronic pancreatitis.
