In order to discover the effect of external biliary drainage on liver regeneration, we have produced a model system carrying cannula in the common bile duct of rat liver and examined the regeneration capacity of liver after partial hepatectomy under various conditions. Previously we have shown that hepatic cells proliferate by obstructive jaundice alone without partial hepatectomy [Terasaki et al; Jpn J Cancer Res 1991 ;82:170–175]. In the present study, we showed that DNA polymerase-α was induced by partial hepatectomy of rats suffering from obstructive jaundice and the induced level was similar to that of the normal regenerating liver. The level of DNA polymerase-α activity corresponded well to the liver regeneration capacity estimated by mitotic index. Contrary to our expectation, external biliary drainage for obstructive jaundice markedly suppressed the regeneration capacity of the remaining liver which was estimated by DNA polymerase-α activity, mitotic index and [³H]thymidine incorporation. The suppression may be due to the external biliary drainage itself because the liver regeneration of normal rats without jaundice was also suppressed by the biliary drainage. These results suggest that the external biliary drainage seriously suppresses the regeneration capacity of liver at least at the early stage of obstructive jaundice.

“…About 25 years ago, peroral and percutaneous cholangioscopy were introduced as diagnostic methods that yielded additional information after ERCP, allowing a direct visualization of the biliary tree and target biopsies of pathological findings [2,3]. With the introduction of video cholangioscopy, this method was routinely used in many hospitals during exploration of the common bile duct in cases of cholelithiasis [4].…”

“…For the first time, this offered diagnostic options superior to other imaging procedures in this region [8,9] . In choledochoscopy, a general distinction is made between percutaneous transhepatic and retrograde endoscopic access using the so-called "mother-baby" endoscope technique [10,11] . With the frequently used and less invasive "motherbaby" endoscope technique, a thin choledochoscope ("baby scope") is introduced in the bile duct for ERCP via instrument channel of a duodenoscope ("mother scope") ( Figure 1).…”

Different diagnostic procedures exist for the detection of bile duct lesions in clinical practice. However, neither retrograde contrast imaging of the bile duct endoscopic retrograde cholangiopancreatogram nor other imaging procedures allow a safe diagnosis of the lesions. Therefore choledochoscopy may be a useful diagnostic procedure in macroscopic assessing lesions of the bile duct. Even if the diagnostic sensitivity and specificity is not sufficient, first studies suggest an enhanced diagnostic accuracy for choledochoscopy. Since the progress of choledochoscopy has started in the 1970 different improvements were achieved. Meanwhile, the examination can be performed by an examiner and samples can be taken. Image and Resolution quality has improved over the past years, also. The SpyGlass system is a technically advanced cholangioscopic device to provide endoscopic diagnosis in case of inconclusive bile duct findings. Further more, two more lumina allow specific biopsy forceps and optical fibers for electrohydraulic or laser lithotripsy. The most frequent useful insert of SpyGlass in clinical practice are in complex gallstones and bile duct lesions of unclear dignity.
