Is Hepatectomy Necessary in Dealing with Left Hepatolithiasis with Intrahepatic Duct Stricture?

Background: Hepatolithiasis with intrahepatic biliary strictures, more common in Southeast Asia than elsewhere, remains a difficult problem to manage. Hepatic resection has recently been advocated as one of the treatment modalities for hepatolithiasis; however, this procedure is not without risk. This study was designed to achieve complete clearance of the stones, eliminate bile stasis, and avoid the potential risks of hepatic resection in the patient with hepatolithiasis and intrahepatic biliary stricture.Methods: In this prospective clinical trial 13 patients with retained left hepatolithiasis and intrahepatic biliary strictures were included. All the patients met the following criteria: (1) initial surgical procedure for hepatolithiasis, (2) normal gross findings of the left liver, and (3) no obvious clinical evidence of an associated intrahepatic cholangiocarcinoma. After the operation they underwent matured T-tube tract ductal dilatation with percutaneous transhepatic cholangioscopy tube stenting. Choledoschoscopic electrohydraulic lithotripsy was used in five patients after dilatation when impacted or large stones were encountered.Results: Complete clearance of the stones was achieved in these 13 patients. One patient had fevers develop after ductal dilatation, and another patient had mild hemobilia after electrohydraulic lithotripsy. Both recovered uneventfully with conservative treatment. These successfully treated patients remain well, with a mean follow-up period of 20 months.Conclusions: Postoperative matured T-tube tract ductal dilatation and stenting, combined with endoscopic electrohydraulic lithotripsy when indicated, is an effective and safe alternative to hepatic resection for selected left hepatolithiasis with intrahepatic biliary stricture.     

The role of endoscopic lithotomy in the treatment of intrahepatic stones

Although hepatolithiasis is a benign disease, its treatment is still the most difficult one in medical field. Before 1977, we had tried bilioenterostomy at the porta hepatis to expect spontaneous dislodgement of stones. However their results were very poor because of frequent occurrence of cholangitis which leads to hepatic failure or death in 8 of 15 patients. From 1977 to 1981, 35 patients had undergone postoperative cholangioscopy (POC). Complete stone removal was obtained in 24 patients. There were 13 difficult local problems in the remaining 11 patients including 6 being too narrow to permit the passage of the fiberscope, 3 having stones incarcerated, 3 having abnormal distribution of biliary tract and one being a missed stone. From 1981, we have carried out percutaneous transhepatic cholangioscopic lithotomy (PTCL) for the treatment of intrahepatic stones in 16 patients. Because abnormal distribution of biliary tract can be easily detected by PTC and incarcerated stones can be made into small pieces before removal following LASER application. We had succeeded in complete stone removal in 12 patients. 2 patients needed biliary reconstruction or liver resection after PTCL. We concluded that for treatment of the disease of intrahepatic stone PTCL should be considered as the first choice before surgery in order to avoid unnecessary hepatic resection or biliary reconstruction.     

Percutaneous transhepatic cholangioscopic lithotripsy

Since 1983, 14 patients with intrahepatic and common bile duct stones have undergone percutaneous transhepatic cholangioscopic lithotripsy because the stones were too large to be removed using ordinary percutaneous transhepatic cholangioscopy. Stones were completely fragmented in seven cases (six with intrahepatic stones and one with common bile duct stone) and partially disrupted in five cases with intrahepatic stones. Intrahepatic duct angulation and stricture was the factor most often responsible for failure. All the disintegrated stones were removed by subsequent transhepatic cholangioscopy. Amongst the seven patients with complete stone fragmentation, six stones were found with electrohydraulic shock-wave lithotripsy and one with NdYAG laser lithotripsy. Complications of percutaneous transhepatic cholangioscopic lithotripsy using electrohydraulic shock waves were found in three cases, two had transient haemobilia and one had fever and chills after the procedures. They all recovered by conservative treatment. NdYAG laser treatment was expensive, time consuming and inconvenient to use. Percutaneous transhepatic cholangioscopic lithotripsy by using electrohydraulic shock wave is an effective and safe method to fragment biliary stones and to facilitate their removal.

Experience with percutaneous transhepatic fiberoptic choledochoscopy for retained stones in the biliary tract

Summary Residual choledochal stones in 11 patients and stones in the intrahepatic bile ducts in 5 patients were successfully removed by the use of the fiberoptic choledochoscope (FCH-6T), introduced percutaneously into the intrahepatic biliary tract. The reasons for the use of percutaneous transhepatic extraction were: (1) unsuccessful endoscopic papillotomy; (2) unsuccessful choledochoscopic removal via the T-tube tract; (3) high surgical risk; (4) the presence of percutaneous transhepatic biliary drainage for acute cholangitis and acute pancreatitis. All stones were extracted through the liver or the papilla of Vater after crushing them. All minor complications such as pain, vomiting, or fever resolved without further therapy. Percutaneous transhepatic choledochoscopy proved safe and effective for the removal of retained choledochal stones and was essential for the treatment of stones in the intrahepatic bile ducts.     

Percutaneous treatment of common bile duct lithiasis

STUDY AIM: Biliary lithiasis in the main bile duct (particularly retained stones) may be treated percutaneously obviating reoperation or endoscopic sphincterotomy. The aim of this study was to determine risks and pitfalls of this approach. PATIENTS AND METHODS: Forty-two cases of biliary stones treated percutaneously between 1980 and 1998 were reported. Among them, 28 patients had already a biliary drainage and in 14, a drain was placed into the bile duct by transhepatic way or by punction of the intestinal loop of a bilio-jejunal anastomosis. The means to clear the bile ducts included percutaneous endoscopy and contact lithotripsy. Thirty patients had residual lithiasis (after a surgical intervention), 11 a new lithiasis above a bile duct stenosis and in 1 a bile duct lithiasis with a gallbladder lithiasis. RESULTS: Morbidity included four complications (9.5%--one severe) and no mortality. After 2.3 +/- 1 courses, desobstruction was complete in 33 cases (78.5%) and partial in one case (2.5%) allowing to optimize the patient for endoscopic sphincterotomy. Desobstruction failed in eight cases (19%), six patients were successfully treated by surgery and 2 by endoscopic sphincterotomy. CONCLUSIONS: Percutaneous desobstruction of the bile ducts may be proposed as a priority in patients with a biliary drain in place and when endoscopic sphincterotomy is impossible or contraindicated. These manoeuvres have a definitive place in hepato-biliary surgery.     

Primary intrahepatic lithiasis: report of a case treated by laparoscopic bilioenteric anastomosis

Recent advances in videolaparoscopic surgery have made this method the treatment of choice for many biliary diseases. However, it has not been used in certain cases, such as primary intrahepatic lithiasis. The authors report a case of a 62-year-old woman with a history of several episodes of cholangitis. Investigation revealed dilated intra- and extrahepatic bile ducts with intrahepatic stones. The patient underwent laparoscopy, and intraoperative cholangiography disclosed an enlarged common duct with absence of stones and the presence of multiple calculi in the intrahepatic biliary tree. A choledochotomy followed by choledochoscopy was performed, which revealed several intrahepatic pigmented stones that were completely retrieved, followed by a laterolateral choledochoduodenostomy to decompress the biliary tree and to allow the migration of residual or recurrent stones. The patient had an uneventful recovery and was discharged on the fourth postoperative day. After 15 months of follow-up the patient is asymptomatic with normal results of liver function tests. Late postoperative upper digestive endoscopy showed a patent choledochoduodenostomy.     

Intrahepatic lithiasis. Study of thirty-six cases and review of the literature.

In 2,700 operations for biliary tract stones, intrahepatic lithiasis (stones located proximal to the confluence of the main hepatic ducts) was discovered in 36 patients (1.3 per cent). The diagnosis of intrahepatic lithiasis was determined only via intraoperative chalangiography in thirty-two cases (88.9 er cent); in 23 per cent of our cases of intrahepatic lithiasis, jaundice was never observed. This confirms that intraoperative cholangiography should be performed routinely in every case of biliary lithiasis. The removal of stones was generally performed by an indirect approach (papillostomy and/or choledochotomy). In 16.7 per cent of our cases, a direct approach was indicated. It is extremely important, after removal of calculi, to assure ample bilioenteric flow. Our surgical approach was therefore based mostly on the caliber of the biliary tract. When the tract was dilated less that 2 cm (in 20 cases), choledochohepaticotomy with papillostomy was most often performed (12 cases, 60 per cent). When the dilatation was more that 2 cm (12 cases), Roux-en-Y hepaticojejunostomy was performed in all. There was no operative mortality, although the long-term follow-up results were poor in 9.6 per cent of the cases.     

Rendezvous Technique Using Double Balloon Endoscope for Removal of Multiple Intrahepatic Bile Duct Stones in Hepaticojejunostomy After Living Donor Liver Transplant: A Case Report

Cholangitis is a major complication following transplantation. We report a living donor liver transplant (LDLT) patient with cholangitis due to multiple stones in the intrahepatic bile duct during hepaticojejunostomy anastomosis, who was successfully treated with the rendezvous technique using double balloon endoscope. A 64-year-old woman underwent LDLT with right lobe graft and hepaticojejunostomy for Wilson disease. There was bile leakage with biliary peritonitis, which was treated conservatively after transplant. Two years after surgery, she developed reiterated cholangitis due to stenosis of hepaticojejunostomy anastomosis and multiple stones in the intrahepatic bile ducts.Percutaneous transhepatic biliary drainage was performed. The size of the drainage tube was increased, and the anastomotic area was dilated in a stepwise manner using a balloon catheter. The stones were crushed and lithotomy was performed using electronic hydraulic lithotripsy through cholangioscopy. Finally, lithotomy was performed for the remaining stones through endoscopic retrograde cholangiography with the rendezvous technique using the double balloon endoscope.Rendezvous approach with percutaneous transhepatic biliary drainage and double balloon endoscopic retrograde cholangiography was an effective treatment for the multiple intrahepatic stones in hepaticojejunostomy following LDLT with right lobe graft.     

Portal biliopathy

Herein we describe a case of obstructive jaundice and cholangitis originating from choledochal lithiasis secondary to a stricture of the common bile duct in a patient with cavernous transformation of the portal vein. In fact, portal cavernous transformation gives rise to many dilated pericholedochal and periportal collaterals that bypass the portal vein obstruction. Extrinsic compression of the common duct by dilated venous collaterals together with pericholedochal fibrosis from the inflammatory process causing portal thrombosis may lead to biliary stricture and dilatation of the proximal biliary tree. This condition sometimes causes the formation of secondary biliary stones and cholangitis. Treatment in our case could not be accomplished by a biliodigestive anastomosis because the patient suffered from a short bowel syndrome subsequent to extensive ileal resection for splanchnic venous thrombosis. We repeatedly attempted stone removal during endoscopic retrograde cholangiopancreatography (ERCP) but finally resorted to a percutaneous transhepatic approach, which permitted removal of the stones and treatment of the stricture by pneumatic dilatation. The patient remains well 3 years after the procedure and has shown no signs of jaundice or cholangitis.     

A study on postoperative bile duct stricture with intrahepatic stones

From January 1976 through December 1988 we encountered ninety nine cases of intrahepatic stones. Eight of them were complicated with postoperative bile duct strictures which were formed on cholangiojejunostomy in 5 cases, cholangioduodenostomy, hepatic hilum and common hepatic duct in 1 case, respectively. Six cases of them are anastomotic strictures. The stones were mainly composed of bilirubin calcium. We guessed that the bile duct stricture resulted from cholangiojejunostomy without Roux-en-Y in 1 case and anastomotic insufficiency in 5 cases. Intrahepatic stones were removed by percutaneous transhepatic cholangioscopy (PTCS), and the treatment for the stricture was cholangiojejunostomy in 1 case and the dilatation by PTCS in 5 cases, including 3 endoprostheses by pig-tail silicone catheter and 2 internal-external biliary drainage. Two patients who did not undergo cholangioscopic dilatation died of sepsis due to cholangitis. Three of 5 patients who underwent endoscopic dilatation by PTCS could return to social life without recurrence of gallstones. In other two cases an endoprosthetic catheter was removed by PTCS because of dislodgement or obstruction of the catheter after confirming anastomotic strictures had improved. Authors recommended that PTCS should be applied for postoperative bile duct stricture complicated with intrahepatic stone.

Abstract Objective To evaluate the safety, efficiency, indications and procedure of percutaneous transhepatic cholangioscopy (PTCS), using a one-stage percutaneous tract dilation technique, in patients with intrahepatic and/or common bile duct stones. Methods The medical records of 35 cases of intrahepatic and/or common bile duct stones treated by PTCS, using a one-stage tract dilation technique, from January, 2015 to April, 2017 in the Second Affiliated Hospital of Zhejiang University School of Medicine were studied retrospectively. All the patients were treated with lithotripsy and basket stone removal through PTCS using one-stage percutaneous tract dilation technique after percutaneous transhepatic cholangial drainage (PTCD). The perioperative morbitity, stone clearance rate, and stone recurrence rate were analyzed. Results The intrahepatic biliary duct and common bile duct were successfully accessed in all 35 cases using ultrasound-guided one-stage percutaneous tract dilation PTCS technique. The stones were completely removed (level A) in 65.7% (23/35) of the cases including 18 cases of intrahepatic stones and 5 cases of common bile duct stones. The stones were almost cleared (level B) in 22.9% (8/35) of intrahepatic stones cases. Stone clearance was achieved in 31 (88.6%) cases (level A and B). One case suffered PTCD site bleeding and one case had percutaneous transhepatic tract rupture during the secondary stone removal procedure. There were no other serious procedure-related complications such as life-threatened bleeding, bile leak and conversion to laparotomy. With follow-up of 1-28 months, 6 (26.1%) of 23 cases of level-A stones clearance had recurrent intrahepatic stones and cholangitis. Conclusion PTCS using one-stage dilation of the tract, is an effective, safe and alternative minimal invasive method forintrahepatic and/or common bile duct stones when surgery or peroral approach is not indicated.

Abstract Objective To investigate the clinical application of percutaneous transhepatic cholangioscopic lithotripsy (PTCSL) for intrahepatic stones. Methods The clinical data of 194 patients with complicate intrahepatic stone performed PTCSL between February 1, 2008 and December 31, 2016 in Department of Hepatobiliary Surgery, the Second Affiliated Hospital of Guangzhou Medical University were analyzed retrospectively. The procedure was divided into two groups: one step procedure percutaneous transhepatic cholangial drainage and percutaneous transhepatic cholangioscopy were performed simultaneously; Two step procedure percutaneous transhepatic cholangioscopy was performed 3-5 days after percutaneous transhepatic cholangial drainage. Results All the patients were successfully performed by percutaneous transhepatic cholangioscopy. The one step procedure was performed in 28 patients ??14.4%????while two step procedure 166 patients??85.6%??. Operation time was??45.0±8.0??min. Saline solution used for rinse was??6000.0±500.0??mL. The stone clearance status??intrahepatic stones were all removed in 81 patients??41.8%??. Incomplete removal was achieved in 113 patients (58.2%), of which 109 patients of secondary bile duct branch without residual stones. Postoperative complications included 13 patients??6.7%?? with biliary tract infection and 5 patients ??2.6%?? with bleeding. Two patients developed into infection shock and one patient died of multiple organ failure. One hundred and sixty-tow patients (83.5%) were followed up, and the overall recurrence rate for hepatolithiasis in patients who underwent PTCS therapy was 29.6%??48/162??. Conclusion PTCSL is effective in the treatment of selected patients with intrahepatic bile duct stones. Combination of stiff and soft cholangioscopy can reduce the possibility of retaining stones after operation. Compared with one step procedure, two step procedure may result in fewer serious complications.     

Intrahepatic stones. The transhepatic team approach.

OBJECTIVE: The authors reviewed the combined interventional radiologic and surgical management of 54 patients with intrahepatic stones at the Johns Hopkins Hospital. The team approach used large-bore transhepatic stents to access the intrahepatic ducts until they were stone free. SUMMARY BACKGROUND DATA: Intrahepatic stones are uncommon in western countries. As a result, few American institutions have had much experience, and multiple management algorithms have been suggested. Nonoperative, operative, and combination surgical and nonoperative approaches have been advocated. At Johns Hopkins, combined surgical and percutaneous management has been used for 18 years. METHODS: This team approach includes (1) percutaneous placement of transhepatic access catheters, (2) surgery for underlying biliary disease and stone removal, and, when necessary (3) postoperative percutaneous choledochoscopy and stone removal through the transhepatic stents. RESULTS: The median age of the 54 patients was 50 years, and 32 were men. Biliary disease included 27 benign strictures, 7 sclerosing cholangitis, 5 choledochal cysts, 5 parasitic infections, 5 choledocholithiasis, and 5 biliary tumors. Fourteen patients (26%) were treated exclusively with percutaneous techniques. Forty patients (74%) had surgery, including 36 Roux-en-Y hepatico- or choledochojejunostomies with large-bore transhepatic stents. Eighteen of these 40 patients (45%) with multiple intrahepatic stones, strictures, or both required additional procedures after operation. No hospital deaths occurred after any of the percutaneous or surgical procedures. With a mean follow-up of 60 months, 94% of patients were stone free, 87% of patients were symptom free, and 73% have had their transhepatic stents removed. CONCLUSIONS: A combined radiologic and surgical approach with transhepatic stents is a safe and effective method for managing intrahepatic stones.     

The treatment of intrahepatic calculosis by applying helix hydro-jet lithotripsy under video choledochoscope: a report of 30 cases

Background and aims Intrahepatic lithiasis is a common disease in southeast Asia [Sheen-Chen and Chou, Acta Chir Scand 156:387–390, 1990], and a difficult problem of biliary surgery. There is no established method of treating patients with intrahepatic stones [Uchiyama et al., Arch Surg 137:149–533, 2002]. In recent years, resection of the affected liver lobe or segment is the best therapeutic option to completely remove the source of recurrent infection. The need for endoscopic treatment modalities is evident because hepatic resections are combined with a high morbidity and mortality rate [Andersson et al., HPB Surg 2:145–147, 1990; Adamek et al., Scand J Gastroenterol 34:1157–1161, 1999]. Hepatic resection only fit the cases in which the stones localized in one lobe or segment, while it doesn’t fit the cases which have polystones in left and right biliary tract. Duodenoscope can only get the stones in the common bile duct and cannot deal with the intrahepatic lithiasis. The management of intrahepatic lithiasis can only be treated by intraoperative or postoperative choledochoscope. For big stones or compact stones, lithotripsy should be applied. But the laser lithotripsy and the electrohydraulic lithotripsy can cause serious complications such as perforation of bile duct. It needs a safer and more reliable treatment for intrahepatic lithiasis. The aim of our work is to study the lithotrity treatment of intrahepatic lithiasis by using helix hydro-jet under Video Choledochoscope.Materials and methods From March 31, 2003 to October 20, 2004, 30 intrahepatic stone patients were treated. Eighteen of them were women and 12 were men, with ages ranging from 35 to 80 years (mean, 58 years). According to B ultrasound and computed tomography (CT) scan report, there were five cases of intrahepatic lithiasis and common bile duct stones, 25 cases of left and right hepatic duct stones, and one case with giant intrahepatic stone (1.5 × 1.5 × 1.2 cm). Intraoperative or postoperative choledochoscopic helix hydro-jet lithotripsy was applied through a video choledochoscope. For the patients to have the intraoperative choledochoscopic helix hydro-jet lithotripsy, they should be diagnosed correctly by B ultrasound or CT scan. The biliary tract reconstruction by spiral CT scan is as helpful as MRCP or ERCP for clinical diagnosis. For the patients to have the postoperative choledochoscopic helix hydro-jet lithotripsy, they should be diagnosed correctly by T-tube cholangiography and BUS and CT scan. All patients should be verified without stones remaining in the bile duct after lithotripsy by choledochoscopic examination and T-tube cholangiography, and should be examined by BUS again after 6 months to 1 year. We decide whether complications occurred by observation of symptoms and signs after choledochoscopy and lithotripsy.Results Seventy-five intrahepatic stones with diameter ranging from 0.6 to 1.5 cm were successfully fragmentized in 30 patients using of helix hydro-jet lithotripsy. These fragmentized stones mainly are bilirubin stones. The lithotripsy was carried for 45 times and the procedure needs 1–1.5 h. Helix hydro-jet lithotripsy are used in 16 cases during operation and 12 cases after operation; two cases during operation and after operation. Intrahepatic calculosis was cleaned out completely and verified by postoperative choledochoscope examination and postoperative T-tube cholangiography examination. No complications were observed.Conclusion Helix hydro-jet lithotripsy under video choledochoscope is a safe and effective method for the removal of intrahepatic stone. No bile duct damnified and perforation was observed. The procedure is without pain and heat, and the pressure can be adjusted easily. The research provides a new way of using the helix hydro-jet, and a new way of curing the intrahepatic lithiasis.Electronic Supplementary Material Supplementary material is available for this article at     

Is preoperative biliary drainage necessary according to evidence-based medicine?

Preoperative biliary drainage has been in use for a long time and is still being performed today in some institutions, but there has been a long-standing issue as to whether the necessity of this procedure has been proven medically. Many problems existed previously, such as systemic complications due to the difficulty in diagnosing and differentiating obstructive jaundice from jaundice left untreated for a long time, or surgeon-based problems such as a lack of surgical skill or undeveloped surgical techniques, or even inexperience in perioperative patient management. These problems, however, are being overcome with time, and the advantages of preoperative biliary drainage are now being questioned according to evidence-based medicine. Several recent controlled trials have clearly shown that preoperative biliary drainage is not necessary for lower bile duct obstruction, although it was noted that surgery after reduction of jaundice by percutaneous transhepatic cholangial drainage (PTCD) was very easily performed. It is important to understand that preoperative biliary drainage is unnecessary for lower bile duct obstruction, whether the technique follows a percutaneous approach, an endoscopic apporach, or stenting. Although it is still being debated, there have already been several reports regarding whether preoperative biliary drainage is necessary for upper bile duct obstruction, such as hilar bile duct carcinoma. This also needs to be clarified by randomized controlled trials. Aside from preoperative biliary drainage, the utilization of biliary drainage or stenting has been fully recognized as important for removing intrahepatic stones or choledochal stones, as well as for emergency drainage for acute cholangitis and for the treatment of unresectable malignant biliary stenosis. Additionally, percutaneous transhepatic cholangioscopy (PTCS), using the PTCD, or percutaneous transhepatic biliary drainage (PTBD) route, plays a major role not only in the removal of biliary stones but also in the diagnosis of cases in which it is difficult to differentiate between benign and malignant lesions.

Percutaneous transhepatic choledochoscopic removal of intrahepatic stones

BACKGROUND: Treatment of hepatolithiasis is complex and difficult. With the advent of biliary endoscopy and radiological intervention, percutaneous choledochoscopic removal of intrahepatic stones has become a well established procedure. METHODS: Seventy-nine patients with intrahepatic stones that were removed by percutaneous transhepatic choledochoscopy (PTCS) between 1993 and 2001 were studied retrospectively. The results of the procedure and the long-term outcome of these patients were analysed. RESULTS: The success rate of choledochoscopic removal of intrahepatic stones was 76.8 per cent. Complications occurred in 17 patients (21.5 per cent). Removal of stones predominantly on the right side was difficult using this method. Cholangitis occurred in about one third of patients within 3-5 years after PTCS. For patients with a stricture, cholangitis recurred gradually over the years of follow-up. CONCLUSION: Intrahepatic stricture was the major determinant for the recurrence of stones or symptoms. Hepatic resection should be offered to these patients if the disease is localized in one liver segment or lobe. In other cases, percutaneous choledochoscopy and stricture dilatation is a useful solution, and may reduce further damage to the liver.
