title: Arterial vascularization of the operated stomach: highly selective vagotomy, anterior lesser curve seromyotomy, esophageal replacement by transposed stomach after esophagectomy or circular pharyngolaryngectomy.
abstract: The rich vascularisation of the stomach is well known and the remarkable tolerance of the organ to vascular ligatures has been emphasised. However, some clinical observations as well as more and more detailed anatomical studies suggest some modification of this classical concept, especially when operating on the viscus. The aim of this work was to evaluate particularly the importance of parietal ischemia which follows hyperselective vagotomy and the more recent anterior seromyotomy, on the one hand, and the gastrolysis that precedes gastro-esophagoplasty after esophagectomy or circular pharyngolaryngectomy on the other hand. The stomachs of 40 unembalmed adult cadavers were studied by angiography in various ways, according to the operation which was being considered. The findings indicated that hyperselective vagotomy caused an avascular band 2 cm wide along that part of the lesser curve affected by the surgical intervention, and that anterior seromyotomy (allowing for some technical artifacts) caused almost no parietal ischemia, and lastly, that the ischemia from gastro-esophagoplasty varied according to the technique used. Useful conclusions, supported by numerous illustrations, will allow the surgeon to define better the vascular requirements when choosing the procedure to be used, taking account of the clinical situation.
