- gastrojejunostomy
types:
- polypoid / fungating
- ulcerating / penetrating (70%)
- infiltrating / scirrous = linitis plastica
- superficial spreading carcinoma
- confined to mucosa/submucosa; 95% 5-year survival
- patch of nodularity; little loss of elasticity
location:
- 60% lesser curvature
- 30% GE junction
- 10% greater curvature
probability of malignancy of an ulcer:
- fundus 90%
- greater curvature 70%
- lesser curvature 10-15%
