Afferent loop syndrome(ALS) is caused by obstruction of the afferent loop after subtotal gastrectomy with Billroth II gastrojejunostomy. Prompt diagnosis of ALS is important as perforation of the loop occurs. The aim of this study is to ascertain the value of sonography and CT to diagnose ALS. We describe the radiologic findings in ten patients with ALS. The causes of ALS, established at surgery, included cancer recurrence (n=4), internal hernia(n=4), marginal ulcer (n=1), and development of cancer at the anastomosis site(n=1). Abdominal X-ray and sonography were performed in all cases, upper GI series in five cases and computed tomography in two cases. The dilated afferent loop was detected in only two cases out of ten patients in retrospective review of abdominal X-ray. ALS with recurrence of cancer was diagnosed in three cases by upper GI series. Of the cases that had sonography, the afferent loop was seen in the upper abdomen crossing transversely over the midline in all ten patients. The causes of ALS were predicted on the basis of the sonograms in three of the five cancer patients. In two cases of computed tomography, the dilated afferent loop and recurrent cancer at the remnant stomach were seen. Our experience suggests that the diagnosis of afferent loop syndrome can be made on the basis of the typical anatomic location and shape of the dilated bowel loop in both sonography and computed tomography.

We examined the p53 protein overexpression and evaluated its correlation with pathobiological variables, including: (1) patient age, sex, tumor size, histological type and grade, invasion depth, vascular invasion, perineural invasion and lymph node status; (2) the Ki-67 labeling index in 100 gastric carcinomas; and (3) the DNA ploidy pattern, S phase fraction (SPF), and the proliferation index (PI) in 84 cases using flow cytometry. The positive rate of p53 staining was 48% and the p53 immunoreactivity was independent of variable clinicopathologic factors. No correlation was made between the Ki-67 labeling index with p53 immunostaining and DNA ploidy parameters. Aneuploidy rate was slightly higher in the p53 positive group (55.6%) than the p53 negative group (44.4%)(p=0.097). The mean values of SPF and PI were significantly higher in the p53 protein positive group. Aneuploidy was more often observed in the intestinal type (p=0.038), advanced gastric carcinoma (p=0.015) and lymph node positive group(p=0.039). The above results suggest that although the p53 protein overexpression has no significant correlation with pathological factors and the Ki-67 labeling index, it may play an important role in tumor cell proliferation. Since p53 protein overexpression was slightly higher in the aneuploidy group showing significant correlation with poor prognostic parameters, it is thought that re-evaluation of the p53 mutation by molecular biological study is needed.

The infantile polycystic kidney disease is rare fetal urinary tract anomaly. It is inherited with an autosomal recessive pattern and recurrence rate is 25%. The gene locus is on chromosome 6p. The pathogenesis of infantile polycystic kidney is the primary defect of the collecting ducts. The ultrasonographic finding of infantile polycystic kidney is oligohydramnios, bilaterally symmetrical enlarged kidneys with maintenance of their reinform shape. The differential diagnosis with adult polycystic kidney disease is important. The massive enlargement of the kidneys is rarely seen in adult polycystic kidney disease and the examination of the parents and other members of the family is helpful to confirm the adult polycystic kidney disease. If there is severe renal involvements, stillbirth or neonatal death secondary to pulmonary hypoplasia would be developed. If it were diagnosed before viability, termination of pregnancy is recommended. In a fetus at risk, diagnosed after viability, pregnancy termination is also recommended since this condition is uniformly fatal. We present a case of infantile polycystic kidney.

BACKGROUND/AIMS: We compared the accuracy in the diagnosis of hepatic masses such as hepatocellular carcinoma (HCC), metastasis and hemangioma using enhancing pattern alone with using additional findings, and determined whether the additional findings could improve the diagnostic accuracy. METHODS/MATERIALS: Triphasic spiral CT images were retrospectively analyzed in 83 cases of hepatic lesions,' 40 HCC, 21 metastases, and 22 hemangiomas. Three observers made the diagnosis first by the enhancement pattern of the mass alone, and then, by the whole information. The diagnosis of a lesion was considered correct if the lesion was correctly categorized by at least two observers. Diagnostic accuracies of two sessions were compared with McNemar test. RESULTS: Using enhancing patterns alone, 31/40 HCC (78%), 8/21 metastases (38%), 21/22 hemangiomas (95%) were correctly diagnosed. The frequency of correct diagnosis was significantly improved when all images with additional findings were used: 36/40 (90%) HCC, 20/21 (95%) metastases, 22/22 (100%) hemangiomas (P=0.00006). Metastasis showed most prominent and statistically significant improvement in the diagnostic accuracy (P=0.0004). The number of correct diagnoses for HCC increased without statistical significance (P=0.17). However, the images with additional findings did not significantly contribute to the diagnosis of hemangiomas. The additional finidngs those led to correct diagnosis of metastases were multiple mass (7 cases), coexistence of primary malignancy (6 cases), and metastasis to other organ (1 case). The findings of liver cirrhosis were helpful to diagnose HCC correctly in 5 cases. CONCLUSION: The enhancing pattems of tumors were important in the diagnosis of hepatic masses in spiral CT. However, the additional finidngs were also helpful for the diagnosis of hepatic masses especially for the masses with atypical enhancement pattern. In metastases, the additional findings such as multiple masses or detection of primary malignant focus were useful to diagnose correctly.

The report of the M. pyramidalis was studied in 51 cadavers of Korean adults (male 33, female 18). Origin, insertion and number of this muscle were observed, and the length and breadth were also measured. The results were as follows : 1. The right pyramidal muscle was absent in one male cadaver, and the left pyramidal muscle was absent in two male cadavers. 2. In one male cadaver, pyramidal muscles of both sides had bifurcated origin. 3. In Korean adults, the average length of this muscle was 6.72cm in right, 7.05cm in left, and the breadth was about 2.0cm in both sides. The morphological index was 31.10 in right, and 29.55 in left. 4. In Korean male, the average length of this muscle was 1.93cm in right, 7.42cm in left, and the breadth was 1.93cm in right and 1.92cm in left. The morphological index was 28.70 in right and 26.58 in left. 5. In Korean female, the average length was 6.26cm in right, 6.38cm in left. and the breadth was 2.13cm in right and 2.12cm in left. The morphological index was 35.57 in right and 34.63 in left. 6. Compared with other human races, the pyramidal muscle was less frequently wanting in Asians (3.9%), including the Korean adults, than wanting in European (19.9%), American Whites (20.4%) and Negroes (15.1%). 7. The morphological index of this muscle was little differences existing in male of the human races, but this index was higher in Korean female (35.0) than in Japanese female (24.4) and in American female Whites (25.8). The morphological index was 32.3 in American female Negroes.

PURPOSE: To assess the effectiveness and clinical usefulness of prostate biopsy by automated gun biopsy device under the transrectal ultrasonographic guidance, authors analysed the result of biopsy and the patients status after biopsy procedure. METHODS AND MATERIALS: The subjects consisted of 24 patients with prostatic disease. Biopsy instrument was an automated gun biopsy device loaded with an 18 gauze biopsy needle. All the patients were admitted to the hospital. No analgesics was given. All the procedure was performed with the patient in left lateral decubitus. Biopsy was performed at 2-4 different points of the prostate in 22 cases, but recently, six different points were targeted in two patients. RESULTS: Biopsy specimens were sufficient in 21 cases but insufficient in three cases. Histologic examination of biopsy specimens showed that 13 cases were nodular hyperplasia, eight cases were cancerous and three cases were inflammation. There was no clinically significant complication. There was mild to moderate degree of pain in all patients. CONCLUSION: Tansrectal biopsy of the prostate with an automated gun biopsy device under ultrasonographic guidance is considered relatively easy, handy and useful procedure in patients with prostatic disease. The procedure may be performed on the outpatient basis.
