Billroth-I anastomosis with the biofragmentable anastomosis ring (BAR) in an animal model

In the present study, the Billroth-I anastomosis with the biofragmentable a nastomosis ring was examined in dogs. 24 dogs were randomized into a group of manual suturing (n = 12) and a BAR-group (n = 12). In the group of manua l suturing, a distal gastric resection and gastroduodenostomy with sero-sub mucous suture was performed. In the BAR-group, the distal gastric resection was done with the linear stapler PLC-75, whereby the BAR gastroduodenostom y crossed the stapling line. The dogs were evaluated on p.o. days 4.14, and 30 and tested for bursting strength and bursting location, appearance of m ucosa, hydroxyprolin concentration, and histologic features. There was no f unctional disorder in the gastrointestinal transit in any animal; in summar y with regard to the various parameters, the crossing of BAR and stapling l ine does not represent any additional risk factor in the Billroth-I anastom osis in dogs.
