[Technique of isoperistaltic esophageal gastroplasty. Comparative study of in vitro arterial vascularization].

Operative survival is impaired by anastomotic fistula after esophageal resection and reconstruction. Hypovascularisation of esophageal substitute is essential. Stomach is a useful esophageal substitute however proximal resection of lesser curvature compromises vascularisation of the highest point of fundus which is usually sutured to esophagus. To improve this a new S shape esophagoplasty with isoperistaltique stomach was achieved. Fifteen cadaveric stomachs were assigned to three equal groups prepared as follow: narrow J shape stomachs, large J shape stomachs, large S shape stomachs. The arterial tree was studied following injection of contrast media barium from the right gastroepiploic artery. Proximal arteries of the S shape stomachs were well filled comparing to the others. This was allowed by keeping intact the tronc of the left gastric artery branches, severing the left gastroepiploic artery close to the spleen, and dividing the proximal fundal region as a curve.
