[The endoscopic retrograde cholangiography (author's transl)]

Area of Science:

• Gastroenterology
• Diagnostic Imaging
• Hepatobiliary Surgery

Background:

• Pancreatic diseases can cause prepapillary stenosis of the choledochus, a common finding in pathological examinations.
• Post-cholecystectomy syndrome frequently requires further investigation for organic disease.

Purpose of the Study:

• To evaluate the efficacy of endoscopic retrograde cholangiography in diagnosing biliary and pancreatic ductal issues.
• To compare retrograde cholangiography with intravenous cholangiography for diagnosing papilla Vateri stenosis and bile drainage problems.

Main Methods:

• Analysis of 760 endoscopic cholangiographic procedures.
• Assessment of diagnostic yield for clinical problems.
• Evaluation of findings related to pancreatic diseases, papilla Vateri stenosis, and post-cholecystectomy syndrome.

Main Results:

• Endoscopic retrograde cholangiography successfully addressed the clinical problem in 76% of examinations.
• Prepapillary stenosis from pancreatic diseases was found in 35% of pathologic findings.
• Intravenous cholangiography appeared more informative for bile drainage and papilla Vateri stenosis, identifying common drainage hindrance in 26%.
• Organic disease necessitating reoperation was found in 65% of post-cholecystectomy syndrome patients.

Conclusions:

• Endoscopic retrograde cholangiography is a valuable tool for diagnosing conditions related to pancreatic diseases and biliary stenosis.
• Intravenous cholangiography may provide superior diagnostic information regarding bile drainage and stenosis of the papilla Vateri.
• A significant proportion of post-cholecystectomy syndrome cases have demonstrable organic disease requiring intervention.
