Surgical anatomy of the innervation of pylorus in human and Suncus murinus, in relation to surgical technique for pylorus-preserving pancreaticoduodenectomy

Figure 5 Two cases showing innervation of the pyloric region (Py) in Suncus murinus by whole-mount immunostaining. High magnifications of the boxed areas in A and C are shown in B and D. White arrows show the nerves of Latarjet intended for the antro-pyloric region. Black arrows indicate the nerves arising from the right gastric artery (RGA), running along the pyloric artery (PyA), and reaching the pyloric region. An, pyloric antrum; CBD, common bile duct; Duo, duodenum; E, esophagus; L, liver; LGA, left gastric artery; P, pancreas; RGA/V, right gastric artery/vein; S, stomach. Scale bar = 2 mm in A and B.
