[Reconstruction and functional results after gastric resection]

Depending on the extent of gastric resection, namely total, proximal or distal gastrectomy, different methods of reconstruction are available. These reconstructive procedures have not changed with the implementation of minimally invasive or robotic techniques in general but the spectrum of possible anastomotic techniques has been substantially expanded. Functional, in particular nutritional disorders with subsequent impairment of the health-related quality of life, are often diagnosed after gastric resections. The partial preservation of a gastric reservoir has a positive impact on the extent of these disorders. After total gastrectomy, the placement of a jejunal pouch significantly reduces the incidence of postoperative dumping symptoms. Following proximal gastrectomy, double-tract reconstruction offers certain functional advantages as compared to the simple Roux‑Y reconstruction. In Germany, these reconstructive techniques are only used to a low extent and should be include in the repertoire of oncological gastric surgery with appropriate indications.
