Purpose: To report our experiences of clinical features, treatment method and results of giant cell tumor of 5 patients in proximal fibula. Materials and Methods: Five patients managed with an en bloc resection preserving common peroneal nerve and lateral collateral ligament reconstruction with biceps femoris tendon followed up between January 1997 and July 2001. Preoperative plain radiograph and MRI and bone scan were checked. The recurrence of the tumor was judged by plain radiograph and clinical signs. Lateral instability of knee joint was checked during the outpatient follow-up. Results: The mean age of the patients at the time of operation was twenty- three (21-29). There were one male and four female patients. Dull pain was main symptom and palpable mass was seen in two patients. Peroneal nerve palsy and local recurrence were not observed except one case of temporary peroneal nerve palsy. During the outpatient follow up, one among 5 patients showed slight lateral instability and the other 4 patients showed no instabililty. Conclusion: Giant cell tumor in proximal fibula managed with an en bloc resection preserving common peroneal nerve and lateral collateral ligament reconstruction with biceps femoris tendon showed favorable results.

A combined anterolateral and posterior approach with thoracotomy has been recommended as the traditional surgical approach for the tumors of the thoracic spine. Recently, because of the morbidity associated with open thoracotomy, the thoracoscopically assisted surgical technique was introduced successfully in thoracic spinal surgery. Herein, we report a combined surgical technique for giant cell tumor of the thoracic spine (T10) consisting of bilateral thoracoscopic anterior release of the spine followed by a posterior on bloc spondylectomy and reconstruction by orthopedic surgeons. The thoracoscopic spinal surgery is safe and effective alternative for other open thoracotomic procedures in the approach to the anterior thoracic spine, avoiding the disadvantage inherent to thoracotomy.

A giant cell tumor (GCT) of the distal radius is not common. Curettage with bone cementation is considered as a treatment of choice but, in the case of recurrence, marked cortical disruption, or articular invasion, en bloc excision and reconstruction with proximal fibular bone graft is usual procedure. In reconstruction of en bloc resected distal radius which had recurred GCT after conservative operation, we used the ultrahigh molecular weight polyethylene (UHMWPE) liner with intramedullary rod and bone cement, because the contamination was extent in previous operation and recurrence after fibular bone graft was fearful. This article introduce our new surgical procedure.

Purpose: Endoscopic incision and submucosal dissection (EISD) is a technique that is being implemented for the resection of gastric adenomas and early gastric cancer (EGC). Since EISD requires a high degree of skill and experience, and due to its association with a moderate risk of gastrointestinal bleeding, its use has been limited. The objective of this study is to investigate the clinical benefits of EISD based upon clinical data on the EISD procedure. Materials and Methods: This study was conducted at Soonchunhyang University Hospital and it included 179 gastric adenoma and early gastric carcinoma lesions from 164 patients who had undergone an EISD from February 2003 to May 2005. Results: Among the total of 179 lesions, the distributions of EGC and adenomas were 70.3% (126/179) and 23.4% (42/179) respectively. The sizes of lesions were divided into 10 mm or less, $11{\sim}20\;mm,\;21{\sim}30\;mm$ and greater than 31 mm and each rates are 10.0% (18/179), 46.3% (83/179), 30% (50/179) and 15.0% (28/179). Among 120 cases which could be measured depth of lesion in according to pathologic findings, m1 (0.8%, 1/120), m2 (38.3%, 46/120), m3 (25%, 57/120), sm1 (11.7%, 14/120), sm2 (1.6%, 2/120) were diagnosed as early stages of gastric cancer. The complete resection rate was 85.2% (150/176) and en-bloc resection rate was 96.0% (169/176). Complications as such as perforation and bleeding developed in 4.4%(8/179) and 21.2% (38/179), respectively. Conclusion: EISD is an effective in the endoscopic treatment for gastric adenoma and early gastric cancers. However, further evaluation of this method and long-term follow-up will be necessary for an evaluation of the recurrence rate after resection of a tumor.
