title: [Searching for the optimal reconstructive methods following total gastrectomy].
abstract: Three prospective randomised studies and a clinical experiment were performed to study postoperative weight, body mass index, nutritional and immunological laboratory parameters, gut motility, lipid and carbohydrate absorption, quality of life and gastrointestinal hormone production after total gastrectomy with different reconstructions. The first trial compared Roux-en-Y to a newly introduced aboral pouch construction, while the second study compared these two methods and the aboral pouch reconstruction with a preserved duodenal passage version. Improved lipid absorption and quality of life was detected for the aboral pouch reconstruction. In addition to these, the duodenal passage preserving version resulted in a better iron metabolism, too. The third study compared the aboral pouch to conventional oral pouch, both with duodenal passage preserving versions. No significant difference was detected between these two groups. In the fourth study, a clinical experiment was performed examining pre- and postprandial glucose, insulin, cholecystokinin and somatostatin levels in patients recruited from the first two randomised trials. Significant differences were demonstrated between the various reconstruction types: the duodenal passage preserving reconstruction provided close to physiological cholecystokinin and somatostatin productions, while with duodenal exclusion these levels were abnormally raised.
