Duodenal stasis is a clinical syndrome caused by duodenal obstruction from various causes, resulting in dilatation of the proximal part of the duodenal obstruction and accumulation of chyme. If there are no obvious symptoms, it is not necessary to deal with it. During acute attacks, intravenous nutrition including fat emulsions, nasal cannula decompression and antitussive drugs are given to treat acute gastric dilatation. Usually, it is advisable to have small and frequent meals, make knee-chest position for half an hour after meals, and strengthen abdominal muscle exercise. If conservative medical treatment is not obvious, surgical treatment can be used. Surgical options are: ① free duodenal ligament; ② duodenojejunostomy; ③ duodenal repositioning.
