Endoscopic retrograde cholangiopancreatography (ERCP). Experience with 100 cases.

Endoscopic visualization of the papilla of Vater was achieved in 98 of our first 100 attempts. Cannulation was successful in 87% of cases, achieving pancreatography alone in 29, cholangiography alone in 27, and both in 31. The relevant duct was adequately visualized in 72.5% of patients with biliary tract disease and in 72% of those with pancreatic disease. Complications were acceptably few. The procedure has proven valuable in difficult cases of obstructive jaundice and biliary type pain syndromes without jaundice. Many questions remain, however, as to its value in the diagnosis and evaluation of pancreatic disease.

Prenatal Fetal Abdominal Ultrasonography and Diagnosis

Despite the advent of gray scale recording, the feasibility and advantages of antenatal fetal ultrasound diagnosis have not received sufficient attention. This paper describes ultrasound fetal abdominal anatomy and illustrates prenatal diagnosis based on anatomical landmarks.

Antenatal Ultrasonic Demonstration of Fetal Bowel

Although ultrasound evaluation of the adult gastrointestinal tract is largely impossible because of bowel gas, the fetal bowel is fluid-filled and therefore not subject to this limitation. In our experience, the fetal bowel pattern can be recognized and antenatal abnormalities detected.

Ultrasound Diagnosis of Common Bile Duct Dilatation

The use of ultrasound in the differential diagnosis of obstructive jaundice has been previously reported. Although common bile duct dilatation has been demonstrated, criteria for its accurate identification have not been stressed. This report describes findings and relationships helpful in recognition of a dilated common bile duct. It is important to identify this structure, since it could otherwise be confused with surrounding vessels.

Ultrasound diagnosis of cerebrospinal fluid abdominal cyst.

A case of cerebrospinal fluid cyst, a rare intra-abdominal complication of ventriculoperitoneal shunting, has been diagnosed preoperatively by ultrasound.

USE OF ENDOSCOPIC RETROGRADE CHOLANGIOPANCREATOGRAPHY IN THE DIAGNOSIS OF PANCREATIC FISTULA A case report and review of the literature

The diagnosis in a case of pancreaticocolonic fistula, presenting with gastrointestinal bleeding, was made by endoscopic retrograde cholangiopancreatography (ERCP) and verified surgically. The clinical picture and pathogenesis of pancreaticoenteric fistulas are reviewed.

Ultrasonographic diagnosis of fetal hydronephrosis in utero

Ultrasonography offers a noninvasive method to visualize antenatal or neonatal anatomy which will lead to early detection and treatment of abnormalities. In these 2 cases, ultrasound allowed prompt diagnosis of hydronephrosis despite normal physical examination and laboratory values at birth.

Ultrasound Visualization of the Pancreatic Duct and Its Clinical Application

The use of ultrasound in the diagnosis of pancreatic disease is well established. Pancreatitis, pancreatic carcinoma and pseudocyst can be demonstrated clearly. However, the ability to visualize the pancreatic duct has not been clearly established.

Ultrasonic Diagnosis of the Bladder as a Symptomatic Pelvic Mass

Diagnostic ultrasound for pelvic masses is now a well established modality. Its ability to distinguish between fluid-filled and solid lesions is important in the diagnostic study of pelvic masses. Two cases are presented of bladder distension causing clinical symptoms suggesting pathology outside the urinary tract, which when finally evaluated by ultrasound proved bladder distension as the etiology of the symptoms.

The value of B-scan ultrasound following intrauterine fetal transfusion.

B-scan ultrasound performed in 6 patients for a total of 15 intrauterine fetal transfusions provided quick, easy, and reliable confirmation of the fetal intra-abdominal placement of transfused blood.
