[Reconstruction techniques after partial and total gastric resection].

The domains of gastric surgery are nowadays oncological resections, often as part of multimodal treatment concepts. Depending on the extent of the gastric resection as total, proximal or distal (or subtotal) gastrectomy, different methods of reconstruction are available. These reconstruction procedures have not basically changed with the implementation of minimally invasive or robotic techniques but the spectrum of possible anastomotic techniques has been substantially expanded. Functional, in particular nutritional disorders with subsequent impairment of the postoperative health-related quality of life, are often observed after gastric resection. After surgical resection these disorders principally occur less frequently with partial preservation of a gastric residue. After (total) gastrectomy, the placement of a jejunal pouch significantly reduces the incidence of postoperative dumping symptoms. Following proximal gastrectomy, double-tract reconstruction provides certain functional advantages as compared to the Roux‑en-Y.
