[Functional and motor study of retrosternal esophageal plasties].

The stomach may be used for esophageal reconstruction after resection of esophageal cancers. The aim of this study was to assess the motility of retrosternal esophagoplasty (RO) following the Akiyama procedure in 6 men (mean age: 56.7 years), at least two months after surgery by means of two techniques: a) manometry of the transplant with a multilumen perfused catheter in 50 and 40 cm from the incisor teeth including spontaneous (5 min) and poststimulation recordings, b) an isotopic method for assessing the gastric emptying of a meal labelled with 111In for the liquid phase and with 99mTc for the solid phase, compared to 12 volunteers as controls. Baseline pressure was 11.2 +/- 2.4 H2O cm without spontaneous activity. After dry and wet deglutition (5 ml of water), 6 patients showed synchronous rise in pressure, having mean amplitude of 12.7 +/- 2.3 cm H2O and lasting 4.3 +/- 1.2 s. Liquids T1/2 was 16.2 +/- 7.8 min in controls (p less than 0.01) and solids T1/2 was 17.7 +/- 6.4 min vs 61.7 +/- 16.5 min (p less than 0.001). The lack of propagated activity associated with rapid emptying of the meal through the plasty with no discrimination between solids and liquids suggests that RO does not participate actively in digestion.
