The authors retrospectively reviewed the efficacy of percutaneous catheter drainage in treatment of abdominal abscess associated with fistulas. One hundred sixty four consecutive patients with abdominal abscesses drained percutaneously since 1985 at department of Radiology, Wonkwang University Hospital were studied. Among these, 13 patients were found to have fistulous communications to the biliary duct, the intestinal tract, or the renal calyx. Eleven patients (85%) were successfully treated without surgical intervention while two patients (15%) needed surgical drainage and fistulectomy. The duration of drainage ranged from 7 days to 9 months. Initial drainage of abdominal abscess was performed in the hospital, but 5 of 13 patients were discharged with a tube in place and were followed up as outpatients. In conclusion, percutaneous catheter drainage is an effective and safe means of treating abdominal abscesses with fistulas.

Two cases of squamous cell carcinoma arising in benign cystic teratoma of the ovary are reported because of the rarity of this condition. No similar cases have been recorded yet in Korean literature. Furthermore, two different co-existing malignant tumors were encountered in one of these cases; a squamous cell carcinoma arising in a benign cystic teratoma of the right ovary and a serous cystadenocarcinoma of the opposite ovary. The latter metastasized to the right ovary. Important points in diagnosis and management of this complication in the operating room are briefly discussed.

Modified biliary Gianturco stents were placed in 27 patients with obstructive jaundice. From July 1990 to October 1992, 46 two-seven connected stents of 8-12mm in diameter (Myungsung Meditech, Seoul, Korea) were placed in 5 patients with benign biliary stricture and 22 patients with malignant biliary stricture in three university hospitals; 12 in Chonbuk National University Hosptial, 12 in Wonkwang University Hospital, and 3 in Chonnam National University Hospital. Nineteen were men and eight were women, ranged in age from 34 to 76 years(average, 55 years). The stents were placed percutaneously through a transhepatic approach using a 8.5Fr. Introducing sheath. All stents were placed successfully without any technical failures or procedural morbidity or morality. All patients complained dull abdominal pain for 1 to 3 days after the stent placement. In a follow-up period of 7-46 weeks, reocclusions were observed in one of the patients with benign stricture (20%) and three of the patients with malignant strictures (16%). Two patients with recurrent jaundice due to the obstruction of the stent were treated with placement of additional stent, one patient was treated with external catheter drainage. Migration of stent occurred in one patient. The application of the expandable biliary metallic stent is suggested as an effective treatment for benign and malignant biliary obstructive jaundice.

PURPOSE: To evaluate the effectiveness of superselective arterial embolization in symptomatic renal angiomyolipoma by assessing tumoral changes and clinical symptoms in long term follow up after embolization. MATERIALS AND METHODS: For the treatment of their condition, nine patients with symptomatic renal angiomyolipoma underwent ten superselective arterial embolization procedures. In all patients, angiomyolipoma had been diagnosed by computed tomography (CT), and in two, had been confirmed by ultrasonography-guided aspiration biopsy. The embolic materials used were absolute alcohol in four sessions, absolute alcohol mixed with lipiodol in three, and Giantruco coils in three. In all patients, follow-up after embolization lasted for between 12 and 54 months, and involved the use of CT. We reviewed retrospectively patients' clinical symptoms, and changes in the size and internal components of tumors, as seen on preembolization and postembolization CT scans. RESULTS: On postembolization angiography, devascularization of the tumor was seen in all patients; the initial symptoms disappeared and tumor size decreased during the follow up period. In nine patients, tumor size decreased after embolization by between 26 and 92%. During the long term (over 12 months) follow up of all patients, seven tumors with a considerable angiomyogenic component markedly decreased in size, but tumors in which the mature fatty component was substantial became only slightly smaller. Reembolization was performed in one patient. CONCLUSION: Superselective arterial embolization is effective in the management of symptomatic renal AML; during long-term follow-up, tumors became smaller and clinical symptoms improved. Embolization is more effective in tumors in which the angiomyogenic components is large.
