Braun enteroenterostomy with stapled occlusion of the afferent limb has been advocated to treat bile gastritis and to avoid the motility effects of Roux-en-Y gastrojejunostomy. However, the motility effects of stapled occlusion are unknown. Myoelectric activity and histologic features were studied after stapled occlusion of the small bowel in a canine model. A 35 cm "recirculating loop" was created with a side-to-side anastomosis, beginning 25 cm from the ligament of Treitz. Serosal electrodes were placed at 5 cm intervals on the loop; at a second operation in one dog and simultaneously in three dogs, the bowel was occluded midway between two electrodes with 4.8 mm staples. Fasting recordings were obtained at weekly intervals to 6 months after surgery and were analyzed for slow wave frequency proximal and distal to the staple line and for propagation time of phase 3 of the migrating myoelectric complex across the staple line. The side-to-side anastomosis did not alter myoelectric activity. However, after stapled occlusion of the small bowel, the slow wave frequency dropped from a mean of 18.2 +/- 0.4 cpm proximally to 15.4 +/- 1.0 cpm distally (p less than 0.05). This correlated with loss of myogenic continuity in three of four animals. Propagation of phase 3 slowed across the staple line (115 +/- 27 seconds versus 47 +/- 9 seconds) (p less than 0.02). The bowel lumen recannulated in all animals. Stapling across the small bowel alters myoelectric activity, and occlusion of the bowel lumen may not be permanent.
