[Prevention of reflux by jejunal transposition--a clinical study (author's transl)].

The prevention of duodenogastric reflux by a jejunal transposition was studied in 11 patients following Billroth II to Billroth I reinterventions. For this purpose intragastric lysolecithin and bile acids were measured. While resected stomachs with a 25 cm isoperistaltic jejunal transposition showed normal reflux values, shorter jejunal segments still had a pathological reflux. The role of the jejunal transposition as an antireflux procedure in ulcer surgery is discussed.
