Colorectal cancer is one of three leading cancer of gastrointestinal tract. Medical records of 42 patients with colorectal cancer who underwent operation at Hospital No175 between 2/1994 and 2/1999 were investigated retrospectively. The disease mainly has been seen in over 30-year patients. Endoscopy diagnosed 94.4% of patients, while that for X-rays is 79.4%. The patients were operated depending on the location of tumor. Surgical wound infection occurred in 31% and anastomotic fistula occurred in 4.7%. There was no death post-operation

The colorectal cancer is one of three leading cancers in the digestive tract. A study on the medical records of colorectal cancer in Hospital 175 during 1994-1999 has shown that the disease occurred mainly in ages of more than 30. 94.4% of patients diagnosed by endoscopy and 79.4% of patients diagnosed by X-ray. The indication for operation depended on the position of tumor. The infection in the incision occurred in 31% of patients and fistula in anastomosis occurred in 4.7% of patients. There was no postoperative death

212 patients suffering from colorectal cancer are analyzed, the author have following remarks: 1. Colorectal cancer generally occurs in individuals 40 years of age or older. Ration of men to women: 1.82. 2. Incidence of malignant lesion: rectum 36.32%, sigmoid: 16.04% righ colon: 15.57%, left colon: 14.15%, tranverse colon: 8.02%, cecum: 9.09%. 3. Treatment: right hemicolectomy 20.75%, left hemicolectomy: 7.55%, colectomy: 14.62%, subtotal colectomy: 2.83%, miles: 14.15%, artificial anus: 30.19%, by-pass: 3.77%, exploration: 1.42%. The early results of post operative: post operative complications were: 8.9%; post operatative: post operative mortality was:1.98%.

Study was conducted cross on the sections from 3cm and 5cm of tumor upper edge of 125 patients with gastric carcinoma. Results: the percentage of existence of tissue cancer at the section that above the tumors 3cm and 5cm was 20.8% and 10.4%, respectively. The percentage of existence of tissue cancer at the cross section 3cm and 5cm was higher than invasive type in comparison with intestinal type (28.3% vs 16.5% and 15.2% vs 7.6%), in undifferentiated carcinoma, adenocarcinoma and Signet-ring cell carcinoma comparison with duct carcinoma (36.8%, 37.5% and 26.3% vs 9.7% at cross section 3cm and 21.1%, 18.8% and 10.5% vs 3.2% at cross section 5cm), in tumors with diameter >2cm and ≤5cm comparison with tumors ≤2cm (27% vs 7.1% at cross section 3cm and 14.3% vs 0% at cross section 5cm), in invasive carcinoma of sero comparison with shorter invasive carcinoma and at last in carcinoma of gland metastasis comparison with tumors without gland metastasis (4.7% vs 11.4% at cross section 3cm and 16.7% vs 4.5% at cross section 5cm).

The incidence of small and micro gastrointestinal stromal tumors is increasing significantly because of the enhanced health consciousness and advanced endoscopic technology. But there still is controversial in the biological behavior and clinical treatment of GIST. The treatment of the GIST with endoscopic technology has obvious advantages. This method can remove tumor and avoid significant trauma. In this paper, the biological behavior, clinical evaluation and endoscopic treatment of the GIST are discussed.

Endoscopic submucosal dissection (ESD) is increasingly being considered an essential component of treatment for early gastrointestinal cancers and subepithelial tumors. The ESD technique owes its popularity to the development of sophisticated instruments used for ESD. With an increase in the number of ESD procedures performed, there is rapid development in the number and types of endoscopic accessory devices used for such procedures. Despite the large numbers of new devices developed and marketed, the use of ESD instruments and accessory devices is largely determined by individual preferences and experiences. Accessory devices frequently used during ESD are important tools for ESD techniques. Each instrument possesses characteristic advantages and disadvantages associated with its use, and no one instrument is superior in all respects to others. In this article, we review the characteristics of endoscopic electrical knives, cap and hood, and hemostatic devices commonly used in ESD.

Since its initial introduction in clinical practice, endoscopic ultrasonography(EUS) has been considered as a valuable tool for the diagnosis and staging of gastrointestinal cancers. With the improvement of equipments in the past decade, EUS-guided fine needle aspiration (EUS-FNA) techniques has been greatly developed, which opens a new avenue to therapeutic EUS. At present, endoscopic ultrasonography (EUS) has been widely applied in the clinical practice of the diagnosis and management of gastrointestinal cancers. In this paper, we summarize the latest data of the applications of EUS in the diagnosis and management of gastrointestinal cancers.

Gastric cancer is the 2nd most common cancer in Korea. Poor prognosis and high incidence of complications are expected for advanced gastric cancer. Surgical treatment is the only therapeutic modality that has a potentially curative effect. Endoscopic treatment is indicated for palliation, symptomatic relief, hemostatis and oral nutrition. With the introduction of uncovered self-expanding metal stents in the early 1990s, endoscopic stents have evolved dramatically over the past 20 years and is primarily used to palliate symptoms of malignant obstruction in patients with inoperable gastrointestinal cancer. Malignant tumours were the source of bleeding in 5% of patients with overt upper gastrointestinal bleeding (UGIB). Patients presenting with tumor-associated UGIB have substantial blood loss at presentation. Initial hemostasis occurs in almost all patients, with endoscopic therapy, but rebleeding frequently occurs and early rebleeding is associated with poor survival.
