Gastric cancer is the most common malignancy and the second leading cause of cancer-related death in Korea. Age-adjusted annual incidence of gastric cancer per 100,000 persons is 62.8 for male and 25.7 for female. The proportion of early gastric cancer among surgically treated gastric cancer patients was 28.6% in 1995, 32.8% in 1999, and 47.4% in 2004. Screening upper endoscopy is quite commonly performed in Korea, and the proportion of early gastric cancer in the screened population is almost 75%. Gastric adenoma is considered to be a very important precancerous lesion. Gastric adenomas are actively treated in Korea, and at least 1/3 of the gastric adenomas with high grade dysplasia show cancerous focus when endoscopically resected. The prevalence of Helicobacter pylori is decreasing in Korean population, which may lead to the decreased incidence of gastric cancer in the near future. Paradigms of the diagnosis and treatment of gastric cancer are rapidly changing in Korea. Efforts to establish robust scientific data for new approaches are strongly required. The proportion of early gastric cancer among all gastric cancers has been and will be more increased in Korea.

Endoscopic resection has been established as one of the treatment options for selected cases of early gastric cancer in Korea. Yet the indications, best treatment methods, management of complications and follow-up methods after the procedure are still uncertain. Some large-scale multicenter studies have recently been reported in Korea. In this review, I will provide an overview of the recent published articles and future directions for endoscopic resection of early gastric cancer.

Barrett's esophagus is a metaplastic change of the esophageal mucosa, such that the normal squamous epithelium is replaced by specialized columnar epithelium. During the last decades, there has been a significant change in the definition, endoscopic diagnosis, pathologic diagnosis, surveillance and management of Barrett's esophagus. Because of the rising prevalence of gastroesophgeal reflux disease in Korea, problems related to Barrett's esophagus are expected to be much more common in the near future. In this review, methods of endoscopic diagnosis of Barrett's esophagus are discussed in detail. Management strategies in the context of Korean epidemiology are also suggested.

In our series with old electrical burn around the the wrist, there are several characteristics: for example, bad scarring in palm and volar aspect of wrist and distal forearm, large multiple defects of the flexor tendons, low median and ulnar nerve palsy, and occasionally insufficient blood supply. Between 1992 and 1995, we treated 8 cases of 7 patients with staged reconstruction. 4 patients with bilateral involvements had below-elbow amputee of contralateral upper extremity. The common approachs in each were soft tissue coverage, staged tendon reconstructiuon, and opponensplasty. The length of time between the injury and tendon reconstruction was 9 months on an average. Soft tissue coverage consisted of: 1. free tissue transfer (n=3), 2. abdominal (n=3) or groin (n=2). Total numbers of flexor tendon reconstruction were 26. Among them, staged reconstruction using silicone prosthesis were done in 18 tendons and primary tendon graft following tenolysis were done in 8 tendons. The time between first and second stage tendon reconstruction was 4.13 months. In all cases, opponen-splasty using extensor indicis proprius (n=4), extensor pollicis longus (n=2), and extensor digiti mini- mi (n=l), were performed. Good functional improvement of the hand were obtained in all cases. Patient s satisfaction were much better than the degree of functional improvement of the hand.

Endoscopic resection is accepted as the standard treatment for early gastric cancer (EGC) without lymph-node metastasis. The indications for endoscopic submucosal dissection (ESD) have been expanded from the standard indications of endoscopic mucosal resection. Recently, clinical data supporting further expansion of ESD have been accumulating. In Korea, recent large scale studies have reported favorable long-term outcomes for EGCs that meet the expanded indications, with 5-year overall survival rates similar to those of EGCs meeting the absolute indication. Additionally, several reports on comparison of long-term outcome after endoscopic resection versus surgical treatment have been published. This review elucidates the feasibility of endoscopic resection for EGC, based on evidence from long-term outcome in Korea. There are still some limitations associated with retrospective analyses and subsequent biased analysis of outcome based on the post-treatment diagnostic groups and problematic follow-up loss.

Gastrointestinal tract is the most common location of extranodal lymphoma and 95.4% of gastrointestinal lymphoma is non-Hodgkin type. Although gastrointestinal lymphoma is usually secondary to nodal lymphoma, it can present as a primary gastrointestinal lymphoma with the majority being in the stomach (74.8%). In South Korea, the most frequent histological subtype of gastric lymphoma is extranodal marginal zone B-cell lymphoma of mucosa-associated lymphoid tissue (MALT), followed by diffuse large B-cell lymphoma. Gastrointestinal lymphoma typically presents with nonspecific symptoms, and endoscopic findings are quite variable. So, the diagnosis is mainly dependent on the histopathological evaluation. Treatment of gastrointestinal lymphoma is dictated primarily by the histopathological type and the stage of the disease. This review will discuss the histopathological classification, staging systems, clinical features and treatment of gastrointestinal lymphoma.
