Obstructive syndrome due to a bezoar in a B-II gastric stump. Endoscopic treatment.

Three cases of a phytobezoar in B-II-gastrectomy are considered in relation to their development around a suture thread acting as precipitating factor; the bezoar was responsible for the presenting obstructive syndrome. Endoscopic diagnosis and definitive treatment by removal of the bezoar together with the thread after cutting the fixed end is stressed. Various kinds of treatment proposed by other authors for the common types of bezoar are discussed.
