BACKGROUND: McKeown first described two autopsy cases of esophageal small cell carcinoma (SMC) in 1952; about 230 cases have since been reported in the literature. Small cell carcinoma has been reported to account for 0.4% to 7.6% of all esophageal malignancies. SMC of the esophagus as regarded as having a poor prognosis with frequent systemic dissemination. Choice of treatment remains controversial. MATERIAL AND METHOD: From August 1987 to December 1998, a review of the records and histologic sections of 8 patients with primary small cell carcinoma of the esophagus seen in 11 years was undertaken. RESULT: Small cell carcinoma of the esophagus constituted 1.5% of all esophageal cancers. The median age was 61.5 years (range from 42 to 71 years). Seven patients were male, tumor was mainly located in the middle and lower thirds (6 cases) of the esophagus. Pure SMC is 5 cases, and mixed SMC is 3 cases. Operative procedure were as follow: transthoracic esophagectomy with thoracic or cervical reconstructon in 7 patients, transhiated esophagectomy with cervical reconstruction in one. The operative death was none. Adjuvant chemotherapy was performed in 7 patients except one who had poor general condition. Recurrence was observed in 4 patients (mediastinal LN, abdominal LN, SCN, bone). The overall median survival was 15.9 months. Only one patient survived for more than 5 years. CONCLUSION: We considered that esophageal SMC should be regarded as a systemic disease, and multimodality treatment including chemotherapy should be used. Surgery may be offered in selected patients to manage local disease as part of a chemotherapy based treatment program.

The present study evaluated the effects of guided tissue regeneration using biodegradable membrane, with and without calcium-phosphate thin film coated deproteinated bone powder in beagle dogs. Contralateral fenestration defects(6 x 4 mm) were created 4 mm apical to the buccal alveolar crest on maxillary canine teeth in 5 beagle dogs. Ca-P thin film coated deproteinated bone powder was implanted into one randomly selected fenestration defect(experimental group). Biodegradable membranes were used to provide bilateral GTR. Tissue blocks including defects with overlying membranes and soft tissues were harvested following a four- & eight-week healing interval and prepared for histologic analysis. The results of this study were as follows. 1. The regeneration of new bone, new periodontal ligament, and new cementum was occurred in experimental group more than control group. 2. The collapse of biodegradable membranes into defects were showed in control group and the space for regeneration was diminished. In experimental group, the space was maintained without collapse by graft materials. 3. In experimental group, the graft materials were resorbed at 4 weeks after surgery and regeneration of bone surrounding graft materials was occurred at 8 weeks after surgery. 4. Biodegradable membranes were not resorbed at 4 weeks and partial resorption was occurred at 8 weeks but the framework and the shape of membranes were maintained. No inflammation was showed at resorption. In conclusion, the results of the present study suggest that Ca-P thin film coated deproteinated bone powder has adjunctive effect to GTR in periodontal fenestration defects. Because it has osteoconductive property and prohibit collapse of membrane into defect, can promote regeneration of much new attachment apparatus.

Dural metastasis associated with chronic subdural hematoma is very rare in patients with malignant neoplasms; it may be difficult to distinguish malignant neoplasms from chronic subdural hematoma. Chronic subdural hematoma is usually a late manifestation of malignant tumors, which contributes to the severity of the prognosis. The scans obtained by using magnetic resonance imaging or computed tomography may be misleading when a subdural hematoma masks the underlying tumor. Herein, we report a case of a subdural hematoma with dural metastasis of unknown origin in a 45-year-old woman; however, the neoplasm was not detected until autopsy.

Any foreign body in the esohagus means an acute danger because of the impending perforation followed by mediastinitis, the impending erosion of bigarteries, and impending aspiration in the care of esorhageal occlusion. Nowadays, foreign body can reliably be removed hy endoscopy, and do not perforate the wall, not changed their form. Complication at the endoscopic extraction of foreign body, that requre surgical intervention are very rare. We presented a case of esophageal foreign body complicated with esophageal ulcer in a 83 years old male.

BACKGROUND: The origin site of carcinoma invading esophagogastric junction is variable. It may arise from squamous cell carcinoma of low esophagus, adenocarcinoma arising from Barrett's esophagus, adenocarcinoma of gastric cardia, or extension from proximal stomach cancer. In Korea, the majority of adenocarcinoma invading esophago-gastric junction seems to arise from proximal gastric carcinoma. MATERIAL AND METHOD: We reviewed the data of surgically-resected gastric adenocarcinoma involving esophagogastric junction in KCCH between 1988 and 1999. RESULT: There were 212 cases. Male to female ratio was 156 to 56. Age distribution was between 22 and 78. Variable surgical approaches including median laparotomy, laparotomy with left or right thoracotomy, left thoracotomy, and thoracoabdominal approach were used. Postoperative pathologic stages were : Stage IA-7, IB-11, II-25, IIIA-73, IIIB-34, and IV-57. Curative resection was performed in 199 patients, and total gastrectomy was performed in 200 patients. There were 77.4%(164 cases) with esophageal involvement, 74.1%(157 cases) with tumor involvement in the abdominal LN, and 8%(17 cases) with mediastinal LN metastasis. Operative mortality was 3.3%, and over-all 5 year survival rate was 35%. CONCLUSION: There are various surgical approaches and many things to consider for surgical resection, thoracic and abdominal approach may need for obtain proper resection margin and adequate lymph node dissection in stomach cancer invading esophagogastric junction.

BACKGROUND: In an effort t enhance long term patency of coronary bypass grafts, utilization of arterial conduits have been on an icrease. With the same objective, we have been using the right gastroepiploic artery (RGEA) in coronary artery bypass procedures since 1998. The current paper has been undertaken with the aim of assessing the apropriateness, problems, and short term results of using the RGEA as an arterial graft conduit by studying the postoperative clinical results of 100 patients than received coronary artery bypass grafting (CARG) with this artery. MATERIAL AND METHOD: Between May of 1998 and May of 1999, an analysis of the mortality, postoperative myocardial infarction, and the need for IABP insertion as a result of low cardiac output were made between 100 consecutive patients undergoing CABG with the RGEA. There was one postoperative death due to cerebral infarction. Postoperative complications/morbidity comprised myocardial infarction in 2, cerebral infarct in 3, reoperation due to bleeding in 1, mediastinitis in 1, and low cardiac output syndrome necessitating IABP in 3 patients. Complicatons related to harvesting of the arterial grafts were not experienced in any of the patients. CONCLUSION: The results of the current data show that utilization of the RGEA in CABG is not associated with increased mortality/morbidity and demonstrates satisfactory short term results suggesting the usefulnessof this conduit as an arterial graft.

We managed surgically a case of local recurrence in esophageal cancer Twenty month after transthoracic subtotal esophagectomy and csophago-gastrostomy, he su(fared from dysphagia. Chest CT and percutaneous needle aspiration biopsy showed. Local recurrence involving residual esophagus, thyroid gland, posterior membraneous portion of trachea. We did cervical esophagectomy, laryngectomy thyroidectomy, partial resection of trachea and reconstruction with free jejunal antograft successfully.
