N/A Extracorporeal shockwave lithothripsy was performed in the intrahepatic stone patients (n = 18) by Dornier MPL 9,000 with ultrasound guidance. The patients had T-tube (n=9) or percutaneous transhepatic biliary drainge tube (n =9). Average treatment session was four and shock wave numbers were in the range of 3,604 to 12,000 (average 6,288 shocks). Intrahepatic stones were removed completely in 16 patients over a 3 month period by ESWL and combined stone extraction maneuver such as cholangioscopic or interventional radiologic method. Extracorporeal shock wave lithothripsy was very helpful in facilitating extraction of stones in unfavorable location or located above the severe stricture. In summary, extracorporeal shockwave lithotripsy followed by percutaneous stone extraction will provide an improvement in the success rate and duration of treatment required for complete removal of primary hepatolithiasis.

Even until recently, the only tool for designers to express their architectural forms has been Euclid geometry. However, new attempts have been made by contemporary designers to interpret the phenomenological complexity of the modern world and environment, and they realized that Euclid geometry is limited in representing full extent of their interpretation, and the need of a nonlinear approach as the presentation method to represent the intricacy is inevitable. The fractal theory, as an expressed form of chaos, now influences arts, music, economics, and other areas, let alone the science and mathematics. And this theory is being applied by some contemporary architects to generate the architectural forms. Fractal geometry is composed of self-similarity, randomness, irregularity, and unpredictability, and the character of its form composition can be described as scaling and skew, overlapping, repetition and gradation, and so on. They are diversely applied to modern architectural works and concepts. The purpose of this study is to understand basic concepts and form-generating method of fractal geometry as a rule of nature, to find the value and the application method in architecture, and finally to suggest future direction.

N/A Serum TLI and Amylase were studied in 20 patients before and after endoscopic retrograde cholangiopancreatography. None of the patients develops clinical acute pancreatitis. Significant increase in serum TLI and Amylase was found after ERCP (p<0.05). Serum TLI peak was observed at 1 hour and Amylase peak at 6 hours. A significant linear relation was found between serum TLI and Amylase 1, 6, 24 hours after the examination.

Afferent loop syndrome (ALS) accompanying acute pancreatitis is characterized by abdominal pain, vomiting and elevation of serum amylase. Thus, it is difficult to differentiate ALS from other causes of acute pancreatitis. However, the history of gastrectomy can be an important clue for diagnosing ALS. We experienced two cases of ALS accompanying acute pancreatitis. The laboratory findings of the patients showed elevation of serum amylase and they were initially diagnosed as only acute pancreatitis. However, the diagnosis were modified as ALS with the aid of computed tomography. After appropriate management, the abdominal pain disappeared and serum amylase level decreased. In conclusion, ALS should be considered as a cause of acute pancreatitis in patients who have the elevated level of serum amylase and a history of gastrectomy.

N/A Benign biliary stricture represents a significant clinical problem, despite of the technological development that has facilitated diagnosis and management. Without proper treatment, it could cause recurrent cholangitis, biliary cirrhosis, liver failure, and death. There are several e- tiologic factors in benign biliary strictures but almost all cases are related to biliary operation, especially cholecystectomy. At Asan Medical Center, from July 1989 through June 1993, nineteen patients were man- aged for post-operative biliary strictures with surgery and radiologic intervention. Nine pa- tients were treated with surgical repair (Roux-en-Y choledocho- or hepaticojejunostomy); ten patients were treated with radiologic and endoscopic intervention (9 endoscopic or tran- shepatic balloon dilatation with stent placement and 1 balloon dilatation only). All patients had the history of previous biliary scrgery, 15 cholecystectomy or CBD explo- ration, 2 choledochoenterostomy, and 2 endoscopic papillostomy. There was no motality after any proce- dure and mean period of follow-up was 10.2 months (3 36 months) for both groups. In sur- gery group, 8 patients (89%) showed successful outcome but in radiologic intervention group, only 4 patients (40%) showed successful outcome. Minor complications after procedure were 4 cases in surgery group and 3 cases in radiologic intervention group but there was no major complication in both groups. Mean period of hospital stay was 6 days (1 16 days) in radiolog- ic intervention group and 23.1 days (19&5 days) in surgery group. Five patients required retreatment because of recurrent strictures after endobiliary stenting. In these patients, 3 Roux-en-Y hepaticojejunostomy was performed, 1 pancreaticduodenectomy was done because of a possibility of malignancy and 1 PTBD was done because the patient refused the surgery. In conclusion, Radiologic intervention for benign biliary strictures provides temporary relief of symptom and might be an alternative treatment, especially in poor risk patients. However, open surgery (mucosa-to-mucosa anastomosis) is superior to radiologic intervention for definite treatrnent of postoperative biliary strictures because of fewer problems that require fur- ther therapy and excellent outcome.

N/A We inserted self-expandable metallic stents in 16 patients with primary intrahepatic stones for the correction of intrahepatic strictures after complete rensoval of intrahepatic stones. All the patients had previous history of abdominal operations for removal of intrahepatic stones. The criteria from insertion of expandable metallic stents was recurrent stenosis after successful balloon dilatation. Inserted metallic stents were Gianturco-Rosch stents (24F) and the stents were inserted via T-tube or percutaneous transhepatic biliary drainage (PTBD) track, In the fallow-up period of average 12 months (9-15 months), 14 patients (88%) out of 16 patients had relief of pruritus and improvement of liver function. But two patients with secondary biliary cirrhosis showed no improvement of clinical symptoms and signs. In conclusion, these findings suggest that expandable metallic stents will be useful in the management of intrahepatic stricutures, which recurred after successful balloon dilatation, in the patients with primary intrahepatic stones.

N/A Expandable metallic stents were implanted in 9 patients with malignant (4 patients) or benign (5 patients) biliary stenoses. Five patients with benign strictures (intrahepatic stones with intrahepatic strictures, n=4; intrahepatic and extrahepatic stones with common bile duct stricture, n= 1) and four with malignant biliary strictures (cholangiocarcinoma, n=4) were treated with expandable metallic stents via percutaneous or transpapillary route. The patients with benign disease had failed treatment with surgical reconstruction and transhepatic balloon dilatation. In the three of the four patients with cholangiocarcinoma, relief of jaundice was observed. Patients with benign strictures have done very well. Our experience shows that expandable metallic stents can be inserted with little discomfort for the patients and with relatively few complications. They will provide good palliation in patients with malignant obstructive jaundice and benign strictures.

N/A Percutaneous cholecystostomy is a techniue to obviate cholestectomy or surgical cholecystostomy in high risk patients. We evaluated 12 relatively high risk patients who underwent percutaneous cholecystostomy in recent 1 year. Overall success rate of percutaneous cholecystostomy was 92%(12/ 13). Relief of pain and defervescence could be observed promptly in almost all patients. In 4 cases of acalculous cholecytstitis, the catheters were removed successfully after resolution of acute inflammation. 3 cases of calculous cholecystitis were treated with elective cholecystectomy after resolution of septic condition. Percutaneous stone removal was performed via the enlarged tract with stone basket or other mechanical devices in 3 cases of calculous cholecystitis. Two cases of tube dislodge and 1 case of mild bile leakage were the complications of this procedure without significant mortality or morbidity. Percutaneous cholecystostomy is a fast, low risk and effective treatment of acute cholecystitis in poor surgical risk patients.

Endometriosis is defined as the presence of endometrial tissue outside the uterus. We experienced 51-year-old woman with symptom of epigastric pain and sign of a palpable mass on the left quadrant abdomen. A cystic mass in the tail area of the pancreas was found on CT scan and was removed surgically. It was a cystic mass originated from the mesentery and separated from the pancreas. It was diagnosed as endometrial cyst histopathologically. (Korean J Gastroenterol 2001;37:389-391)
