Triple arthrodesis is performed to obtain stable stature and walking, to eliminate pain, to correct the deformities of the foot. This is the result of 92 feet triple arthrodesis over a period from 1976 to 1991 at the Department of Orthopaedic Surgery, Yonsei University College of Medicine. The results are as follows 1. Mean age was 17.6 years, ranged from 10 to 51 years. 2. Of the total of 92 feet, sequelae of poliomyelitis was the most common etiology with 58 feet(63%). 3. Most common type of foot deformity was talipes equinovarus with 52 feet(56%). 4. Internal fixation was done with staple or Steinmann pin combined with autogenous bone graft. Among them, using of 2 staples was the most common fixation method, 47 cases(51%). 5. As necessary, triple arthrodesis was combined with tendo-calcaneus lengthening, plantar fasciotomy, posterior capsulotomy, modified Jones operation and tibiotalar arthrodesis. 6. Final results were ideal. in 22 cases(24%), good in 51 cases(56%), fair in 16 cases(17%) and fail in 3 cases(3%). 7. There were 2 cases of pseudoarthrosis and 1 case of residual equinus deformity after operation. In conclusion, triple arthrodesis was the efficient method of treatment for the deformed feet in skeletally matured patients.

Mirizzi syndrom is a rare disorder characterized by obstruction of common hepatic duct due to impacted gallbladder neck or dystic duct stone and is an uncommon cause of obstructive jaundice. Authors experienced one case of Mirizzi syndrome mimicked lobulated intraductal tumor.

PURPOSE: To analyze clinical, radiological and pathological features as well as clinical outcome after surgical treatment of patients with secondary chondrosarcoma arising from osteochondroma(tosis). MATERIALS AND METHODS: We retrospectively reviewed clinical records, radiographs, pathologic slides of 14 patients. Nine patients were male and five were female. The mean age was 34 years. The mean follow-up period was 54 months. RESULTS: All patients had a history of previous mass since childhood or puberty. Preexisted osteochondroma was single in 3 patients and multiple in 10. Remaining 1 patient had multiple osteochondromatosis with enchondromatosis. MRI clearly provided thickness of cartilage cap, which was over 2 cm except in 2 cases. Chondrosarcoma was grade 1 in all except 1 case, which was grade 2. Wide excision was performed in 10 patients, marginal excision in 3 and amputation in 1. Twelve patients were doing very well without evidence of disease. Among 3 patients with marginal excision, 1 patient had local recurrence and 1 patient died of disease. CONCLUSION: Comprehensive understanding of clinical, radiological and pathological features of secondary chondrosarcoma is warranted for accurate diagnosis. The best result can be expected with early recognition of malignant change of osteohcondroma(tosis) and wide excision.

PURPOSE: To investigate prognostic factors influencing on local recurrence, distant metastasis and event-free survival of liposarcomas. MATERIALS AND METHODS: Fifty-two patients managed for liposarcomas since 1993 were analyzed respectively in the view of prognostic influence of patient age, tumor size, location, histologic type, histologic grade, resection type, surgical margin, chemotherapy and radiation therapy on local recurrence, distant metastasis and event-free survival. The mean follow up period was 39 months. The univariate and multivariate regression analysis were performed for statistical evaluation. RESULTS: The local recurrences occurred in 11 patients (21.2%) and distant metastasis in 4 patients (8%), Event-free survival rate at 4 year follow up was 67%. In univariate analysis, histologic grade, surgical margin, chemotherapy and radiation therapy were significant prognostic factors on local recurrence (p<0.05). However, histologic grade lost its significance in muitivariate analysis. Trunk location revealed higher rate of distant metastasis than extremity location. In univariate analysis on event-free survival. histologic grade and chemotherapy were significant factors (p<0.05). No factor remained significant in multivariate analysis. CONCLUSION: Considering selection bias, positive surgical margin was negative prognostic factor on local recurrence. Liposarcomas arisen in trunk revealed higher rate of distant metastasis. There was no independent prognostic factor on event-free survival of patients with liposarcomas.

Diffuse tremendous thickening of gastric wall caused by excessive proliferation of the mucosa of unknown causewas first decribed by Menetrier in 1888. The disease is highly uncommon, but the exact preoperative diagnosis iscrucial because of the more excellent prognosis than other malignant lesions including gastric lymphoma andinfiltrative gastric carcinoma. The authors recently experienced a case of Menetrier's disease which had beendiagnosed as gastric lymphoma preoperatively. Radiologic differentiation is not impossible between this extermelyrare disease and other mimicking malignant lesions, that is the reason why we introduce radiographic findings ofthe case by comparison with gastric lymphoma of giant rugal type and infiltrative gastric carcinoma. Typical upperG-I series findings of the case are: 1) Enlarged tortuous proximal gastric rugal folds only along the greatercurvature, 2) Perpendicular lines of barium spicules trapped by apposed folds with clubbed or forked appearance,3) Abrupt transition of transion to normal stomach, 4) No luminal narrowing and retained but sluggish peristalsis.Thus radiologists can diagnose Menetrier's disease scrupulously based on critical application of enlarged foldspattern and extent of the lesion in association with other radiologic features and clinial history of fairly longduration. Brief review of clinical and pathologic features about Menetrier's disease is included.

A simple and convenient management system in coding and storage of the pathologic diagnoses was developed by generating the dBASE III with IBM-PC microcomputer. The program named "Pathology Slide Bank" can store about 3,600 data according to the SNOP coding in a standard 51/4 inch floppy disk and retrieve the data within two minutes.
