Summary of the morphological comparisons between sham jejunum and the differing limbs in RYGB. A: villus height, with Roux and common limbs significantly longer than both sham and BP limbs. B: mean enterocyte diameter, with no difference between the limbs, suggesting differences in length are due to enterocyte number rather than volume. C: crypt depth, increased depth in all limbs after RYGB compared with shams. This was partly due to an increase in crypt column cell count (D). Lastly, Roux and common limbs, but not BP limb, had increased numbers of goblet cells in both villus (E) and crypt (F) compared with shams. Compared with sham: *P < 0.05; **P < 0.01; ***P < 0.001.
