dentate but the valva is very wide and the
ampulla is relatively thick.
In our study, we diagnosed one tumor in the pancreas, one in the
ampulla, and one in the choledochus.
A 6 mm x 60 mm bare metal stent was inserted into the cystic duct (Figure 2(a)), and an 8 mm x 100 mm bare metal stent was inserted from the midcystic duct through the
ampulla of Vater into the duodenum.
One patient was converted to laparotomy with continued endoscopy to locate the
ampulla of Vater, which was successful.
Additional risk factors for ERCP-related hemobilia which should be mentioned are variant anatomy, especially anomalous location of the
ampulla, aggressive biliary balloon dilation or intraductal biopsying, vascular anomalies (e.g., associated with hereditary hemorrhagic telangiectasia), and transbiliary ductal drainage procedures (e.g., EUS-guided choledochoduodenostomy and hepaticogastrostomy) [8, 21-24].
Endoscopic retrograde cholangiography (ERCP) was performed to investigate the biliary or pancreatic duct, but cannulation of the
ampulla of Vater could not be performed successfully due to the invasion of the tumor.
In order to make a step forward to a better understanding of oviductal MMPs in llama, the aims of the present study were to establish how MMP2, MMP9 and their main inhibitors (TIMP2 and TIMP1, respectively) were displayed in each oviductal segment:
ampulla, isthmus, UTJ and papilla, by the quantification of their mRNA expression levels and the proteins localization.
Endoscopic cannulation of the
ampulla of Valor: a preliminary report.
The patients were divided into those with difficult cannulation and those with unidentifiable
ampulla based on the EUS-BD indication data.
Large paired spermathecae in 8 and 9, with the ovoidal
ampulla joined to a thick duct, slightly shorter than
ampulla diameter; the almost sessile and ellipsoidal diverticulum projects from the ental and lateral portion of duct (Fig.
In 27.18% of women, an expansion of uterine tubes all along was found; at the same time, the expansion in the
ampulla was available in 33.98%.
However, very few case reports of obstructive jaundice from metastatic malignant melanoma to the
ampulla of Vater have been reported.
