Esophageal replacement: gastric tube or whole stomach?
BACKGROUND
The stomach can be used either in its entirely or as a greater curvature tube for esophageal replacement.


METHODS
The study compares the gastric tube (group A; n = 112) to the whole stomach whose lesser curvature is denuded (group B; n = 100) in terms of technical complication and alimentary comfort. The clinical results are substantiated by assessment of the eating performance of patients and control subjects at a test meal, measurement of the gastric dimensions before and after both tailoring procedures, and intraarterial staining of the gastric wall.


RESULTS
Major differences between the two groups are cervical anastomosis stenoses (22.3% versus 6% [A versus B]; p = 0.008), fistulas (7.9% versus 1%; p = 0.0209), number of meals and snacks per day (4.6 versus 4; p = 0.0275), sensation of early fullness at meals (52.4% versus 17.8%; p < 0.0001), ratings given to the long-term alimentary comfort (presymptomatic condition = 10 points) (7.6 versus 8.8 out of 10 on average; p < 0.0001), and calories consumed in 1 minute at a test meal (59% [p < 0.05] versus 77% of those consumed by control subjects). The volume of the stomach is reduced by a range of 21.4% to 47.2% after tubulization (group A) whereas it increases by a range of 4.9% to 17.4% after denudation of the lesser curve (group B). Intraarterial staining of the gastric wall reveals the poor vascularity of the upper-most segment of the greater curve.


CONCLUSIONS
Slight increase of the gastric capacity and maintenance of the submucosal vascular network account for the better results achieved with the whole stomach.
