Villus height before and after operation. Average (±SEM) villus height from C57BL/6 mice after either sham resection (transection and reanastomosis only) or 50% proximal SBR housed in the clean room. The intraoperative segment (intraop) was removed from the ileum 1 cm distal to the anastomosis at time of operation (sham or SBR) or 3 days later at the time of harvest (postop). *Indicates P < .05 sham postoperative vs sham intraoperative; #, P < .05 SBR postoperative vs sham postoperative.
