Considering the newly discovered choledochus
cyst and involvement of the head of the pancreas, the possibility of cephalicpancreaticoduodenectomy arose.
Endosonography enables to visualize tumourous lesions of duct choledochus
and Wirsung's duct.
The previously described method (Beppu et al., 1987) was modified as follows; in mice (n = 5), a laparotomy was performed under ether anesthesia, and the duodenal side of the ductus choledochus
was ligated, as described by Appels et al.
Endoscopic retrograde cholangiopancreatography showed minimal dilatation of the choledochus
and Wirsung duct.
The midgut extends from from the opening point of the ductus choledochus
into the duodenum, to the junction of 2/3 proximal and 1/3 distal parts of the transverse colon (5, 7, 12).
The lesser omentum did not have fat except along the bile duct (ductus choledochus
) near the duodenum.
As it happens, the bile eliminated through the ductus choledochus
, and also pancreatic juices eliminated through the principal and accessory pancreatic ducts, are disposed of in the second portion of the duodenum (Krause), where there are fewer BGs than in the first portion, thereby reinforcing the hypothesis that the main function of the BGs is to neutralize the gastric acidity (Leeson & Leeson; Lipski et al., 1992; Lockhart et al., 1959).
