A new sonographic technique for demonstration of the common bile duct is described in a prospective study of 200 patients. The mean diameter of the normal common duct was 4.1 mm. A common duct greater than 7 mm in diameter can be seen in (a) nonjaundiced patients with gallstones and/or pancreatitis, or (b) jaundiced patients with common duct obstruction by stone or tumor. A common duct greater than 11 mm in diameter is strongly suggestive of obstruction by stone or tumor.

113 cases of pancreatic and renal disease studied by both ultrasound and computed tomography (CT) were analyzed retrospectively. CT provided a diagnosis when pancreatic ultrasound was unsuccessful due to overlying bowel gas or obesity and when renal ultrasound was unsuccessful due to obesity, reverberations from ribs, small lesions, or multiple lesions. Conversely, ultrasound provided a diagnosis when CT was unsuccessful due to lack of fat planes or respiratory motion. CT usualy distinguished carcinoma from pancreatitis when ultrasound showed a focal echogenic mass. CT resolved renal cyst from neoplasm when ultrasound showed a mixed echo pattern mass.

23 deaths of patients with severe asthmatic dyspnea were analyzed. There was no correlation between clinical presentation and cause of death certified by post-mortem examination. The cause of death was found outside the airways in 14 patients. Of diagnostic-therapeutic implications are the relative frequency of spontaneous pneumothorax (5) and pulmonary embolism (3). Six times another cause of death was discovered (like tumor invasion, arterial thrombosis, hemorrhagic pancreatitis, myocardial infarction). Acute asthmatic death was prone to happen in the middle-aged asthmatic with less than two years of bronchial asthma. Here like in 5 patients with chronic obstructive airways disease lack of awareness of the seriousness of the patients' state, sometimes cessation of cortisone long-term therapy, seldom abuse of bronchodilator-aerosols seems to be important for the lethal outcome.

Ultrasound is high frequency mechanical vibration. As far as is presently known, there are no harmful effects of ultrasound at the energy levels used in currently available commercial ultrasonic scanners. Ultrasonic studies are independent of organ function, are painless, and require nor special preparation. Ultrasonic scanning is useful in the diagnosis of pancreatic disease, especially in the detection of complications of pancreatitis such as pancreatic abscess or pseudocyst, and in diagnosing pancreatic carcinoma. Gallstones and dilation of the biliary tree can be detected ultrasonically even when the patient is jaundiced. Primary liver tumors and hepatic metastases can often be demonstrated. Intraabdominal abscesses are better investigated by ultrasound than by any other means currently available. Ultrasonic scanning also provides a sensitive means of detecting ascites. Ultrasonic control of needle placement has been suggested for pancreatic and liver biopsy, for aspiration of intraabdominal fluid collections, and for percutaneous transhepatic cholangiography. Ultrasonic B-mode scans provide undistorted images of cross sections through the abdomen which can be used in radiotherapy planning to localize tumor masses and to place kidney shields accurately. Organ volumes can be estimated from a set of ultrasonic B-mode scans without any assumptions being made as to the shape of the organ.

The ultrasonic demonstration of compression of the anterior (ventral) wall of the inferior vena cava by the pancreatic head was proved to be a reliable sign of neoplasm enlarging the pancreatic head in 10 patients. It would appear that this sign is less reliable and probably not as important diagnostically in patients with pancreatic head enlargement secondary to pancreatitis or pseudocyst. This sign must be constant and reproducible on longitudinal scans done with a single transducer pass in suspended inspiration. This sign was not seen in 50 patients who had no evidence of pancreatic disease.

To aid in case selection for pancreatoduodencetomy and to gain information on the technical management of this operation and its complications, records of 279 patients who were treated for neoplasm or pancreatitis by this procedure between the years 1957 and 1975 were reviewed. The overall operative mortality was 12.5 per cent and was 10.7 per cent for the years 1969 throught 1974. The use of vagotomy did not prevent postoperative bleeding from the stomach, and the use of a stent did not make a statistically significant difference in morbidity or mortality. Postoperative hemorrhage is an ominous complication and is best treated conservatively until blood loss cannot be replaced. Preoperative serum bilirubin levels above 20 mg/100 ml indicate a two-stage operative procedure as does the presence of right upper quadrant sepsis. The resection of malignant disease of the duodenum and lower bile duct is followed by a high mortality and requires total pancreatectomy if a satisfactory pancreatojejunostomy cannot be constructed.

The case is reported of a 46-year-old man who was succesfully operated for a tumor that had its origin in the greater curvature of the stomach and grew into the gastrocolic ligament. After two false diagnoses (pancreatitis and retroperitoneal tumor) this tumor was histologically identified as a hemangiopericytoma. The possibility of recurrence and its prevention are discussed.

In 70 patients suspected of having pancreatic cancer, we prospectively compared results of seven diagnostic tests. Subsequent exploration (of 68) and liver biopsy (of two) demonstrated pancreatic cancer in 30, pancreatitis in seven, nonpancreatic neoplasms in nine and nonpancreatic non-neoplastic disease (or no disease) in 24. For detection of pancreatic disease, the best tests were the pancreatic-function test (cholecystokinin-stimulated enzyme outputs) and ultrasonography. The pancreatic scan was nonspecific (P less than 0.001), and thermography was insensitive (P less than 0.001). Endoscopic retrograde pancreatography and arteriography were significantly more sensitive than cytologic study in diagnosis of pancreatic cancer (P less than 0.001). Therefore, when pancreatic cancer is suspected, abdominal ultrasound should be performed first, and if it is negative, a pancreatic-function test next. A positive result from either test warrants an endoscopic retrograde pancreatography for definitive diagnosis. This sequence identified 88 per cent of patients without pancreatic disease and 89 per cent with pancreatic cancer.

Combined echoscopic and echographic examination enables accurate display of the pancreatic region. Furthermore, this method yields reliable results in demonstrating pathological changes of the pancreas caused by acute pancreatitis, acute necrotising pancreatitis, pancreatic pseudocyst and neoplasm of the pancreas. The characteristic ultrasonographic findings in these diseases are presented and the differential diagnosis is briefly discussed.

Apparent obstruction of the main pancreatic duct was seen on the endoscopic retrograde pancreatogram in 50 patients. The final diagnosis was pseudocyst in 15, neoplasm in 15, chronic pancreatitis in 8, acute recurrent pancreatitis in 3, and abscess in 2. Seven patients were normal. This series emphasizes the broad differential approach necessary when confronted with ductal obstruction. Diagnosis is facilitated by accurate evaluation of the ductal and extraductal characteristics, especially the ductal detail at the point of termination.
