BACKGROUND: Endoscopic Ultrasonography(EUS), a combination of endoscopy and ultrasonography is one of the most useful tools for diagnosis of digestive system diseases. EUS is useful in staging the primary tumor invasion and regional lymph node metastasis because of its ability to image the gut wall and adjacent structures in unique detail. We performed a study preoperatively for assessing the accuracy and limitation of EUS in gastric carcinoma. METHODS: In 75 patients(Male 54, Female 21, Mean age 62.3 years) with a gastric carcinoma confirmed by endoscopic biopsy, we performed EUS preoperatively. The results were compared with the postoperative histopathologic staging. RESULTS: 1) In assessing the depth of tumor invasion, EUS accuracy on depth of invasion was 76.0% and overstaging and understaging were 14.7% and 9.3%, respectively. 2) In assessing the lymph node metastasis, the accuracy rate of EUS was 65.3%. A rate of false-positive diagnosis was 27.3%, and a rate of false-negative diagnosis was 24.5%.3) In assessing the incidence of lymph node metastasis for each T stage, the involve rate was 10.5% in pT1, 36.4% in pT2, 95.7% in pT3, 100% in pT4. CONCLUSIONS: EUS is the most accurate diagnostic methods presently available to determine tumor infiltration depth and lymph node metastasis.

The embryological and anatomical features of urachal anomalies have been well defined. Because of the variable clinical presentation, uniform guideline for evaluation and treatment are lacking. Although urachal remnants are rarely observed clinically, they often give rise to a number of problems such as infection and late malignant changes. Therefore, a total assessment of the disease with a particular focus on embryology, anatomy and clinical symptoms, as well as the most advisable management, is called for. Twenty six patients with urachal remnants were treated at the Department of Pediatric Surgery from August 1980 to June 1998. Of these 26, 9 were classified as patent urachus, 11 as urachal sinus, 4 urachal cyst, 1 urachal diverticulum and 1 alternating sinus. The group consisted of 11 males and 15 females. The age distribution was 20 neonates, 3 infants, 2 preschoolers and 1 adult. Infection was the most frequent complication and Staphylococcus aureus was the predominant causative microorganism. Fistulogram was performed in 4 cases and ultrasound examination disclosed cysts or sinus in 7 cases. Excision was performed in 24 patients and incision and draniage in 2 cases as a primary treatment. There was no postopreative complication or recurrence.

Repairing of lacrimal canalicular laceration has some controversies on the golden time of surgery, the suture method, and the materials for stent. Recently, intubation of silicone tubes has become popular for repair of lacrimal canalicular injuries. Thirty-two cases of injured lacrimal canaliculi were repaired with use of silicone tube stents. The surgery can be done with monocanalicular(10 patients) or bicanalicular(22 patient) methods. The follow-up period was from two to eighteen months(mean ten months). Seven cases using the monocanalicular method and nineteen cases using the bicanalicular method were successful. Three cases of monocanalicular method had epiphora with canalicular obstruction due to early loss of the silicone tube. In monocanalicular method, postoperative complications were punctal granuloma(1 case), punctal slits(2 cases), and early loss of the silicone tube(3 cases). In bicanalicular method, postoperative complications were persistent epiphora during the period of intubaion(4 cases), conjunctival irritation sign(3 cases) and loop retraction(1 case). In conclusion, the success rate of bicanalicular stents were higher than that of monocanalicular stents for canalicular laceration. But the bicanalicular stent had some complications including cosmetic problem, possibility of injuries to the normal canaliculus during intubation, conjuntival irritation sign, and loop retraction.

BACKGROUND/AIMS: Electrohydraulic lithotrypsy(EHL) under cholangioscopic control has been performed for difficult bile duct stones. The percutaneous transhepatic approach is technically easy and useful in diagnosis and treatment of bile duct obstruction and stones. Biliary stenting with self expanding metal stent is gaining increasingly wider acceptance as a palliative treatment of bile duct obstruction. METHODS: Between Sep. 1994 and Sep. 1996, EHL under choledochoscopy by percutaneous transhepatic approach was performed in 30 cases(Male: 13, Female: 17). After PTBD with 7F pig tail catheter, the percutaneous transhepatic passage was dilated over guide wire with dilaters of increasing size up to 16Fr in 3-Sdays. In one week, after fistula had been estabilished, choledochoscopy was performed. RESULTS: (1) Mean age was 61.3 years. Mean stone number was 2.5. And mean stone size was 1.6 X 2.3 cm. (2) Com.plete removal of the stone was achieved in all patients(100%). (3) There were no serious complications. (4) In six cases, Endocoils were implanted with successful decompression of obstructions and simultaneous removal of biliary stones located at both side of stricutre. CONCLUSIONS: Percutaneous transhepatic choledochoscopy is easy and safe and assists in the diagnosis and treatment of biliary stricture and the management of difficult CBD stone.

This study analyzed 88 patients who sustained a cervical spine injury during the past 4 years(Jan, 1993-May, 1996) in whom had 33 anterior, 21 posterior interventions were underwent and 34 remaining patients recieved conservative treatment with halovest. In 45 cases of upper cervical injuries, 16 operations were done. Among these, anterior approach was used in 3 patients and posterior approach in 13 patients. In 43 cases of lower cervical injuries, 39 operations were done. The anterior approach was used in 30 patients, posterior approach in 9 patients, and bilateral approached in remaing 4 cases. For patients with a predominent posterior ligamentous or osteoligamentous lesion, we selected anterior approach, when closed reduction was possible. Whenever the facet joint remained interlocked, a posterior approach was chosen. This report does not mentioned priority of anterior procedure at any case. Although clinical experience does not support the experimental data, we examined the reliability of anterior approach with use of internal fixation.

The neck clipping of cerebral aneurysm is a well established treatment for the subarachnoid hemorrhage caused by aneurysmal rupture. However, incomplete clipping of an aneurysm may result in recurrent hemorrhage with serious or fatal consequence. Recently, two patients underwent reoperation for recurrent hemorrhage from the regrowth aneurysm after previous clipping operation. The technical obstacles to surgical treatment of these two patients were perianeurysmal adhesion or scar formation, presence of clip and coating agents and so on. One patient showed good outcome, another patient was dead by pneumonia. In order to detect regrowth of aneurysm, periodic examination is very important for the patient with remnant neck after aneurysm clipping operation.

OBJECT: The aneurysms located in the distal middle cerebral artery (MCA) are uncommon and have not been well investigated previously. To clarify these lesions more fully, we undertook a retrospective analysis of the clinical features and managements of the 9 consecutive patients treated at our institution. METHODS: Nine patients with distal MCA aneurysms treated at our department between 1994 and 2003 were reviewed retrospectively. We performed analysis on the basis of clinical profiles, radiological and intraoperative findings. RESULT: In our series, the incidence of distal MCA aneurysms was 1.1% of all intracranial aneurysms and 3.7% all MCA aneurysms. There were seven ruptured and two unruptured distal MCA aneurysms. All aneurysms were presumed typical saccular aneurysms in the angiographic and intraoperative findings and there were no past medical history, evidence of previous infection, trauma and neoplastic disorders. The nine patients consisted of seven women and two men ranging in age from 42 to 61 years. Eight aneurysms were located in the left side and only one aneurysm in the right side. Five of seven ruptured patients sustained an subarachnoid hemorrhage (SAH) with intracerebral hematoma (ICH) in the initial computed tomography (CT) scans. Although three patients presented transient speech disturbance postoperatively, good clinical outcome was achived in the eight of nine patients. CONCLUSION:Distal MCA aneurysms have tendency of female and left side predominency and easily cause ICH with SAH, but majority of them showed a favorable outcome. It was difficult to find the exact location of aneurysms during dissection. To obtain successful clippng of aneurysms and avoid the operation related complications, surgeons must dissect the sylvian fissure sufficiently and retract frontal lobe carefully.
