Ultrasonographic findings of ovarian cystadenoma

The ultrasonographic findings of 49 ovarian cystadenomas were analized. The results were as follows: 1. Themost common age group was 3rd decade and most patients(83%) belong to active reproductive period. 2. In 80% ofserous cystadenoma the size of the tumor was ranged in 6–10cm in diameter. The large tumors of 16–20 cm indiameter were mostly mucinous cystadenomas. 3. Purely cystic appearance was the most common finding(40%) of serouscystadenoma and thick linear septation with and without solid component was the most common finding (38%) ofmucious cystadenoma. 4. Thick linear septation with solid component was not found inserous cystadenoma. 5. Welldefined nodular projection was found in 3 cases of serous cystadenoma but not identified in mucinous cystadenoma.

The diagnostic value of barium enema in acute appendicitis

Acute appendicitis is the most common acute surgical condition of the abdomen. when the clinical presentationis atypical, barium enema has proven to be safe and useful in confirming the diagnosis and reducing the negativesurgical exploration. However, the performance of barium enema in acute appendicitis has known contraindicationprimarily because of fear of leakage by perforation of the inflammed appendix. This study using barium enema as adiagnostic aid in acute appendicitis with atypical clinical presentation was performed to further support thepreviously noted efficacy and safety of this procedure. The results were as followings: 1. In case of acuteappendicitis with atypical clinical presentation, the use of barium enema as a diagnostic aid increased theaccuracy of diagnosis and decreased the negative surgical exploration. In women between 11 to 50 years old age,especially, it played important role differentiating appendicitis from nonsurgical acute abdomen. 2. The resultsof the study were 92.31% in sensitivity, 7.69% in false positive, 6.9% in false negative, and 10.26% in negativeappendectomy. 4. A simple partial or nonfilling of appendix without other associated possitive finding could notexclude appendicitis, therefore, close clinial observation was necessary. 5. The positive findings of barium enemaand their sensitivity were as followings: 1. Nonfilling of appendix: 9% 2. Partial filling of appendix: 91.7% 3.Displacement or a local impression on temrinal ileum: 100% *, In all cases, combined with a local impression oncecum and/or irritability of cecum or terminal ileum.

Evaluation of hepatobiliary imaging using Tc-99m-DISIDA in hepatobiliary disease

Hepatobiliary scintigraphy using Tc-labelled radiopharmaceuticals is employed primarily for the diagnosis ofacute cholecystitis and for demonstration of biliary tract patency. We conducted a retrospective study of 55patients with hepatobiliary disease from Jun. '84 to Sep. '84 at Taegu Catholic Hospital and tried to determinethe etiology and fine the possible differential points by analyzing the scintigraphic findings. The followingresults were obtained: 1. Tree-like photon defect on hepatic parenchyme was suggested characteristic of completeobstructive biliary diseases, but could be seen in either benign or malignant etiology. 2. The grade of hepatocyteclearance was not useful in detemining whether the cause of obstructive biliary disease was benign or malignant inthis study. 3. Hepatocyte clearance was more severely impaired in hepatocellular disease than in obstructivebiliary disease. 4. The photon defect in porta hapatis with complete biliary obstruction was suggestedcharacteristic of common bile duct cancer. 5. The meniscus appearance at obstructed site of common bile duct waspathognomonic sign of choledocholithiasis. 6. When the gallbladder was not visualized, the differential diagnosisbetween acute and chronic cholecystitis was possible without delayed image by observing the transist time tobowel. The delayed transit to bowel was a favorable of chronci cholecystitis rather than of acute cholecystitis.7. Acute pancreatitis could be easily differentiated from partial biliary obstruction by clinical and laboratoryexamination, but the finding of abrupt narrowing of pancreatic common bile duct with sligt proximal dilatation oncholescintigraphy was also a key point in acute pancreatitis. 8. The segmental dilatation of intrahepatic duct wasthought meaningful sign of clonorchiasis.
