Abstract

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.

배경 : 식도-위 경계부위에 발생되는 암의 원발병소에는 하부식도의 편평상피세포암, 바렛씨 식도에서 발생한 선암, 위의 분문부에서 발생한 선암, 그리고 상부 위암에서 하부식도를 침범하는 경우들이 있다. 이중 국내에서는 식도-위 경계부위를 침범하는 선암의 대부분은 상부위암의 경계부 침범으로 생각된다. 대상 및 방법 : 저자등은 식도-위 경계부위를 침범하는 위암중 1988년부터 1999년까지 원자력병원에서 수술적 절제를 시행받은 환자를 조사하였다. 결과 : 총 212명이 수술을 받았고 남녀비는 156:56 이었다. 나이는 22세에서 78세였고 정중복부절개, 좌 우 흥부절개 및 복부절개, 그리고 흉-복부 동시절개 등이 이용되었다. 술후 병기는 IA가 7명, IB가 11명, II가 26명, IIIA가 75명, IIIB가 35명, 그리고 IV기가 58명 이었다. 199명에서 근치적 절제를 할 수 있었고 200명에서 위의 전절제를 시행하였다. 164례 에서 하부식도의 침습이 있었다(77.4%). 74.1%는 복부 임파절에 전이가 있었고 17례(8%)에서 종격동 임파절의 침범이 있었다. 수술 사망률은 3.3%였고 전체환자의 5년 생존율은 35%였다. 결론 : 또 여러 가지 수술 접근방법이나 수술시 고려해야 할 점들이 많지만 식도-위 경계부위를 침범한 위암의 수술시 충분한 절제길이와 적절한 임파절의 절제를 위하여 흉부 및 복부의 동시접근이 필요할 것으로 생각된다.
