Barrett's esophagus is precancerous lesion of esophageal adenocarcinoma, but this has been rarely reported in Korea. A 81-year-old man with esophageal adenocarcinoma was admitted to our hospital, and we performed a distal esophagectomy and end-to-end esophagogastrostomy. The microscopic examination of the resected tissue revealed the intestinal metaplasia with goblet cells around the esophageal adenocarcinoma, which indicates this was a Barrett's esophagus. We report here on this case along with a review of the relevant literature.

Patients who went through maxillectomy can have severely impaired swallowing, mastication, and pronunciation functions because of palatal defects. Leakage occurs through the nasal cavity while eating, chewing becomes difficult due to the loss of teeth and alveolar ridges, and oral and nasal passages are not separated, leading to hyper-nasal sound, and significantly reducing the quality of life. To prosthetically reconstruct the defect, the weight of the obturator should be reduced as much as possible to minimize dropout because of gravity, and the bulb of the obturator should be properly extended into the defect to get additional retention and stability. In this case of a partially edentulous patient who underwent additional maxillary resection because of tumor recurrence, a metal framework was designed by applying the basic design principles of removable partial dentures. An obturator with improved retention, stability, and support was fabricated through functional impressions. The patient was satisfied with the improved facial expression, mastication, swallowing, and pronunciation, and showed stable occlusion and oral hygiene management during the follow-up period.

Background: Replacement of the esophagus remains a challenge for surgeons involved in esophageal disease. From 1996 to 1999, a total of 27 patients with esophageal cancer underwent free jejunal transfer(12cases) or esophagogastrostomy(15cases). To determine the results such as leakage of anastomosis site, stenosis, reflux esophagitis and operation time, respiratory complications, etc. we reviewed the 4 years experiences. Material and method: Palliative bypass surgery or esophageal prosthesis and cancers of the pharyngoesophageal or esophagogastric junction were excluded in this study. Resection was usually peformed through right thoracotomy and anastomosis was made with EEA staplers in esophagogas-trstomy. In cases of jejunal free transfer, 6cases of proximal esophagojejunostomy were stapled anastomosed and remaining 6 cases and all distal site were hand-sewn anastomosed. All reconstruction was done through posteromediastinal route. Result: There were two mortalities from thoracic esophagogastrostomy and one from jeunal free transfer. Major and minor complications(anastomosis site leakage: 3 cases, graft failure: 2cases etc) occurred in 27 cases. In 15 thoracic esophagogastrostomy cases, 11 patients had mild to moderate reflux esophagitis and 5 patients incurred stricture of the anastomosis. Operation time was about 550$\pm$280 minutes in jejunal free transfer, and about 300$\pm$ 160 minutes in esophagogastromy patients. Conclusion: Post operative reflux esophagitis and dysphagia were more frequent in Ivor-Lewis operation group than jejunal free transfer group; however, respiratory complications and operation time were significantly longer in jejunal (roe transfer group(p<0.05). To minimize the incidence of postoperative reflux esophagitis and dysphagia, patient evaluation focused on jejunal free transfer surgery is better than esophagogastrostomy followed by adequate post operative care.

Purpose: We purposed to evaluate clinical results after undergoing arthrocopic surgery of lateral discoid meniscus in children. Materials and Methods: Retrospective evaluation was executed for the 21 cases which showed abnormal findings of knee joint due to lateral discoid meniscus, from Janunary 1 1999 to December 30 2007. Average observation period was 38.4 months (14months~60 months), and average age was 9.5 years old (7~12 years old). The major clinical findings for knee joint extension limitations were the most common with 11 cases, and there were 8 cases of knee joint pain, 6 cases of snapping, and 10 cases of gait abnormality. The forms of lateral discoid meniscus were 14 cases of complete type, 5 cases of incomplete type, and 2 cases of Wrisberg type. All patient had arthroscopic partial menisectomy and some patient who had meniscus tear had arthroscopic meniscus repair. The clinical results were evaluated using Ikeuchi grading system, and the change of knee joint was observed through routine radiography. Results: The peripheral hypermobility of lateral disciform meniscus was observed in 7 cases. The peripheral tear was observed in 4 cases, where partial menisectomy was along with suture at the same time. The final clinical results were 5 cases of Excellent, 12 cases of Good, 4 cases of Fair. Radiologically, there were 5 cases of subchondral sclerosis and narrowness of hardness at the lateral knee joint, and osteochondritis occurred at the joint facet of external femur in 1 case. In clinical result, meanwhile, there were 20 cases of normal or almost normal and only 1 case of abnormal in IKDC score. Conclusion: Knee joint arthroscopic partial menisectomy for treatment of lateral discoid meniscus is useful, and when accompanied by peripheral disruption, suture is thought to be necessary.

In Fibrous dysplasia(FD) of the jaws, the majority of cases can await the cessation of growth before surgical intervention, and it seems prudent to delay surgery whenever possible until growth has ceased. In craniofacial FD, however, the dangers of dystopia, dystopia and loss of vision may require early surgery to prevent or control cranio-orbital complications. Delaying surgery in those circumstances may be significantly detrimental to such patients. Conservative surgical management of FD is widely practised and we advocate an extension to this conservative treatment by combining surgical recontouring with appropriate osteotomies if indicated, to achieve an optimal esthetic and functional results in craniofacial FD. One case will be presented to illustrate the feasiblility of such combined treatment, to report the uneventful healing of osteotomies in the FD of the jaws, and to demonstrate the use of titanium miniplate fixation in dysplastic bone. The other case had expansile disease of the left facial and fronto-temporal bones and osteolytic change left mandible. This patient complained of severe spontaneous bleeding of left mandibular premolar area and it was suspected as central hemangioma of the left mandible and craniofacial FD. Angiogram disclosed generalized dilation of the external carotid artery and its branches, especially terminal branches of the left facial and inferior alveolar arteries. But no specific abnormalities, such as A-V shunt, venous lake, or early venous drainage, was seen. So it was diagnosed craniofacial FD with hypercellularity and generalized bony recontouring was performed via coronal and transoral approaches.

Maxillary bone defects may follow surgical treatment of benign and malignant tumors, trauma, and infection. Palatal defects often lead to problems with swallowing and pronunciation from the leakage of air into the nasal cavity and sinus. Obturators have been commonly used to solve these problems, but long-term use of the device may cause irritation of the oral mucosa or damage to the abutment teeth. Utilizing implants in the edentulous area for the fabrication of the obturators has gained attention. This case report describes a patient, who had undergone partial resection of the maxilla due to adenocarcinoma, in need of a new obturator after losing abutment teeth after long-term use of the previous obturator. Implants were placed in strategic locations, and an implant-retained maxillary obturator was fabricated, showing satisfactory results in the rehabilitation of multiple aspects, including palatal defect, masticatory function, swallowing, pronunciation, and aesthetics.

We reported a case of chondrosarcoma in proximal tibia in a 44-year-old man. MR images demonstrated a $3.5{\times}20$ cm sized bone tumor. In reconstruction of resected proximal tibia, we used the allograft bone and soft tissue defects were covered by medial gastrocnemius rotation flap and skin graft. There were no local recurrence and distant metastasis and any complication such as secondary infection, nonunion, metal failure at the time of the last follow-up. There was no limitation of knee motion through the appropriate rehabilitaion programs.

Over the past two years the free jejunal transfer have been used in 7 consecutive patients to restore alimentary tract continuity artier the resection of esophagus. Six patients had squamous cell carcinomas and one had esophageal stricture . The patients underwent partial esophagectomy with modified radicAl neck dissection or mediastinal Iymph node dissection. The microvascular anastomosis was performed to the neck vessels in 4 patients and to the in ercostal vessels in 3 patients. Postoperative complications were graft necrosis in one patient, and a temporary anastomotic leakage with spontaneous closure in one patient. Reconstruction of the esophagus was successful in 6 of 7 patients. We emphasize that esophagectomy followed by transplantation of a free jejunal transfer is suitable for esophageal carcinoma or intractable esophageal stricture, and involvement of the midesophagus is not a contraindication to the use of the free Jejunal transfer.
