Intrahepatic bile duct exploration lithotomy is a useful adjunctive hepatectomy method for bilateral primary hepatolithiasis: an eight-year experience at a single centre

Background

To evaluate the perioperative and long-term results of intrahepatic bile duct exploration lithotomy (IHBDIL) combined with hepatectomy for patients with complicated bilateral primary hepatolithiasis.

Methods

A study was conducted involving 56 patients with complicated bilateral primary hepatolithiasis who underwent IHBDIL combined with hepatectomy at our hospital from January 2006 to December 2014. The perioperative and long-term outcomes that were retrospectively analysed included the stone clearance rate, operative morbidity and mortality, and stone recurrence rate. Patients with a preoperative diagnosis of cholangiocarcinoma were excluded.

Results

In all 56 patients, hepatic duct stones were located in the bilateral IHBD. The surgical method was IHBDIL combined with hepatectomy. Postoperative complications occurred in 15 patients (26.8%), 14 patients responded to conservative management, and there was 1 case of postoperative mortality because of hepatic failure. The overall initial success rate of stone clearance was 85.7%, and the final clearance rate was 92.9% following postoperative choledochoscopic lithotripsy. The stone recurrence rate was 13.5%, and the occurrence of postoperative cholangitis was 10.9% during the follow-up period.

Conclusion

IHBDIL combined with hepatectomy is a safe, effective, and promising treatment for patients with complicated bilateral primary hepatolithiasis. The perioperative and long-term outcomes are satisfactory for complicated bilateral primary hepatolithiasis.

Choledochoscopic Holmium Laser Lithotripsy for Difficult Bile Duct Stones

OBJECTIVE

The aim of this study was to evaluate the feasibility and efficacy of choledochoscopic holmium laser lithotripsy as a means of removing resistant extrahepatic and intrahepatic bile duct stones.

METHODS

Clinical data on 28 patients who had undergone choledochoscopic holmium laser lithotripsy were analyzed.

RESULTS

Complete stone clearance was obtained in 24 patients; small numbers of residual stones in the left or right hepatic duct were found in 4 patients. No severe complications such as hemobilia and bile duct injuries occurred.

CONCLUSION

Choledochoscopic holmium laser lithotripsy is a simple, safe, and effective treatment method for patients with resistant bile duct stones.

Complete radiofrequency ablation of hepatolithiasis-associated cholangiocarcinoma and successful management of post-ablation bronchobiliary fistula

This report documented the use of radiofrequency ablation (RFA) in the treatment of hepatolithiasis-associated cholangiocarcinoma and cyanoacrylate glue in the management of post-ablation bronchobiliary fistula. A 47-year-old Chinese woman with 20 years history of extrahepatic and intrahepatic cholangiolithiasis and multiple hepatic segmentectomy, developed hepatolithiasis-associated cholangiocarcinoma. The tumor was successfully treated with RFA but patient developed bronchobiliary fistula. Cyanoacrylate glue was used for occluding the bronchobiliary fistula. CT scan at 3 months showed complete restoration of physiological separation between the biliary and bronchial system. Repeat CT scan showed complete tumor ablation with no signs of tumor recurrence 10 months after RFA. In conclusion, RFA may be a safe and effective treatment option for patients with hepatolithiasis-associated cholangiocarcinoma who are poor candidates for surgical resection. Protection of the integrity of the bile duct and diaphragm during RFA can minimize postoperative complications. In case of development of post-ablation bronchobiliary fistula, cyanoacrylate glue can be used to occlude the fistula, before surgical resection is considered.

Management of intrahepatic stones: the role of subcutaneous hepaticojejunal access loop. A prospective cohort study

BACKGROUND

Patients with intrahepatic stones usually present with recurrent cholangitis, biliary sepsis and intrahepatic abscesses, may develop liver atrophy and may progress to cholangiocarcinoma. Treatment of intrahepatic stones is difficult and the disease progresses in most patients even after adequate treatment. Surgical removal of stones has been the standard management but residual stones and stone recurrence occur frequently whatever the technique. Because of the need for repeated biliary instrumentation, long-term access routes involving percutaneous transhepatic cholangioscopic lithotripsy (PTCSL), hepaticocutaneousjejunostomy (HCJ) and subparietal hepaticojejunal access loop to permit stone retrieval or stricture dilatation have been developed.

PURPOSE

The aim of this work was to evaluate the outcome of subcutaneous hepaticojejunal access loop in the management of intrahepatic stones.

PATIENTS AND METHODS

Between January 2009 and January 2013, 42 patients with intrahepatic stones underwent surgical treatment at the Gastrointestinal Surgery Unit, Main Alexandria University Hospital. Demographic data, details of operative findings, follow up details, and treatment of recurrent stones were analyzed. After approval of local ethics committee, all patients included in the study were informed well about the procedure and an informed written consent was obtained from every patient before carrying the procedure.

RESULTS

Forty-two patients (17 males and 25 females) with intrahepatic stones underwent surgery with construction of a subcutaneous hepaticojejunal access loop. Stones were confined to the left lobe in 25 patients, the right lobe in 3 patients and bilobar in 14 patients. Associated extrahepatic stones were found in 33 patients. Twenty-two patients had associated intrahepatic duct strictures. Five patients with atrophy of segments II and III underwent hepatic resection at the time of access loop formation. The mean operation time was 4.9 h and mean blood loss was 440 mL. Mean postoperative hospital stay was 10 days. Wound infection was the commonest complication, occurring in 5 (12%) patients. There were no specific complications attributable to the construction of the access loop. The subcutaneous access loop was used to gain access to the biliary tree in 28 patients with residual or recurrent stones. A total of 55 procedures (range 1-5) were attempted with successful access achieved in all cases and successful stone clearance in 21 of the 28 patients, and all of them were symptom free for at least 12 months after the last procedure. Partial stone clearance was achieved in the remaining seven patients. These seven patients had different degrees of biliary strictures.

CONCLUSION

The subcutaneous access loop offers the advantage of permanent access for the successful management of retained or re-formed intrahepatic stones with minimal morbidity since it permitted easy access to intrahepatic ducts using the conventional forward-viewing endoscope or the choledochoscope, without the additional morbidity of a biliary-cutaneous fistula or transhepatic access.

Oriental cholangiohepatitis - is our surgery appropriate?

Oriental cholangiohepatitis, or recurrent pyogenic cholangitis is only noted in certain parts of the world, especially South East Asia. Due to increasing immigration the disease is now being seen in western countries also. Treating physicians may face difficulty in managing such cases due to lack of exposure. Furthermore management of such cases is not standardized because of lack of a universally accepted classification system. Here we review the disease and share our long experience with management of these patients.

Recurrent pyogenic cholangitis: disease characteristics and patterns of recurrence

Recurrent pyogenic cholangitis (RPC) is characterized by repeated infections of the biliary system with the formation of stones and strictures. The management aims are to treat acute cholangitis, clear the biliary ductal debris and calculi, and eliminate predisposing factors of bile stasis. Operative options include hepatectomy and biliary drainage procedures or a combination of both; nonoperative options include endoscopic retrograde cholangiopancreatography (ERCP) or percutaneous transhepatic cholangiography (PTC) guided procedures. This current study compares the operative and the nonoperative management outcomes in patients with RPC in 80 consecutive patients. In addition, we aim to evaluate our approach to the management of RPC over the past decade, according to the various degrees of severity and extent of the disease, and identify the patterns of recurrence in this complex clinical condition. Initial failure rate in terms of residual stone of operative compared with nonoperative treatment was 10.2% versus 32.3% (P = 0.020). Long-term failure rate for operative compared with non-operative treatment was 20.4% versus 61.3% (P = 0.010). Based on multivariate logistic regression, the only significant factors associated with failure were bilaterality of disease (OR: 8.101, P = 0.007) and nonoperative treatment (OR: 26.843, P = 0.001). The median time to failure of the operative group was 48 months as compared to 20 months in the nonoperative group (P < 0.010). Thus operative treatment is a durable option in long-term resolution of disease. Hepatectomy is the preferred option to prevent recurrent disease. However, biliary drainage procedures are also an effective treatment option. The utility of nonoperative treatment can achieve a reasonable duration of disease free interval with minimal complications, albeit inferior to operative management.

Hepatic resection for bilateral hepatolithiasis: a 20-year experience

BACKGROUND

There is increasing evidence showing that hepatic resection is probably the best definitive treatment for unilateral hepatolithiasis. However, the role of hepatic resection for bilateral hepatolithiasis is rarely mentioned in the literature.

METHODS

We retrospectively reviewed 197 patients who underwent hepatic resection for hepatolithiasis in Changhua Christian Hospital from December 1987 to December 2007. A total of 156 patients with unilateral hepatolithiasis were defined as the UNI group (control group), and 41 patients with bilateral hepatolithiasis were defined as the BI group (study group). The short- and long-term outcomes were measured.

RESULTS

The BI group had longer operating time (200 min versus 173 min, P = 0.006), lower immediate stone clearance rate (56.1% versus 91.7%, P < 0.001), lower final stone clearance rate (75.6% versus 94.9%, P = 0.001), higher rate of stone recurrence (22.6% versus 6.1%, P = 0.009) and higher disease-related mortality (19.5% versus 5.1%, P = 0.006). Thirty patients with bilateral peripheral stones were indicated for bilateral hepatectomy, but only 20 (66.7%) of them actually underwent the proposed procedure. Of the patients who did not achieve immediate stone clearance, bilateral peripheral stones represented 88.9% (P = 0.044). Of the patients who had stone recurrence, patients less than 35 years old represented 42.9% (P = 0.007).

CONCLUSION

Bilateral hepatolithiasis has worse outcomes than unilateral hepatolithiasis after being treated with hepatic resection. Regarding bilateral peripheral stones, there is often a discrepancy between the extent of stone-affected parenchyma and that of final liver resection, resulting in a lower immediate stone clearance rate. A higher stone recurrence rate was observed among younger population.

Selection of surgical treatment types for intrahepatic duct stones

Backgrounds/Aims

Complete elimination of intrahepatic duct (IHD) stones is difficult and IHD stone disease is frequently associated with various complications, recurrence and sometimes cholangiocarcinoma. Therefore, we analyzed the long-term surgical results and evaluated the management currently considered appropriate.

Methods

Overall 110 patients who had been diagnosed with benign IHD stone disease and who underwent surgical treatment were enrolled in this study. The patients were categorized into three groups according to the type of surgery performed; liver resection (LR) group, intrahepatic duct exploration (IHDE) group and hepaticoenterostomy (HE) group. We compared and analyzed the results of these three groups.

Results

The number of cases in the LR group, IHDE group and HE group were 77, 25 and 8 respectively. The LR group required a longer operation time (p=0.000), more frequent transfusion (p=0.028) and had higher morbidity (p=0.049). However, the LR group had a higher clearance rate (90.9%) (p=0.000) than the other groups. In addition, there were a total of 22 cases of IHD stone recurrence during the follow-up, but there was no statistically significant difference among the three groups. The location of IHD stones was related to a risk factor for incomplete stone removal, but not for recurrence.

Conclusions

The fundamental principle for the treatment of IHD stone disease should be liver resection. However, it can lead to a longer operative time and higher rate of complications than the other procedures. There is also no difference in the IHD stone recurrence rate among the procedures. Therefore, these alternative and minor procedures could also be taken into account for patients with poor preoperative condition.

Intrahepatic cholangiocarcinoma associated with intrahepatic duct stones

OBJECTIVE

It has been well established that the long-term prognosis of intrahepatic duct stones (IHDS) is complicated by the late development of biliary cirrhosis with associated intrahepatic cholangiocarcinoma (IHCC). Despite recent improvements in imaging studies, accurate preoperative diagnosis of IHCC is difficult. Therefore, we attempted to elucidate the clinical features of patients with IHDS with IHCC.

METHODS

We reviewed 80 patients with IHDS and divided them into two groups. The DS group included 72 patients who had only IHDS. The second group was defined as the CC group and included eight patients who had IHDS and IHCC. For diagnosis of IHDS and confirmation of coexisting IHCC, patients underwent various radiological evaluations and additional laboratory tests, such as serum carbohydrate antigen 19-9 (CA 19-9).

RESULTS

There was no significant difference in the symptoms and stone characteristics between the two groups. For the CC group, liver resection was performed in four patients. Three patients underwent curative resection, but only one of these patients was alive at 36 months without recurrence.

CONCLUSION

IHCC with IHDS was difficult to diagnose in the early phase. Therefore, while performing diagnostic studies and surgery for IHDS, one should always consider the possibility of coexisting cholangiocarcinoma.

Outcomes of hepatic resection for hepatolithiasis

BACKGROUND

Hepatic resection is main approach to treatment of hepatolithiasis, but the long-term follow-up results of hepatic resection for hepatolithiasis are rarely reported.

METHODS

A retrospective study was conducted of 87 patients with hepatolithiasis who underwent hepatic resection.

RESULTS

The final stone clearance rates were 95%. There was a significant difference in the incidence of recurrent stones between patients with and without remaining biliary strictures. On multivariate analysis, the presence of residual or recurrent stones was an independent risk factor associated with recurrent cholangitis. The 10-year overall survival rate was 80.3%. On multivariate analysis, the development of cholangiocarcinoma was an independent predictor of survival in patients who underwent hepatic resection for hepatolithiasis.

CONCLUSIONS

The long-term outcomes after hepatic resection were satisfactory in patients whose intrahepatic stones and strictures were completely removed. Cholangiocarcinoma associated with hepatolithiasis was an independent prognostic factor in patients with hepatolithiasis who underwent hepatic resection.

Liver resection as the definitive treatment for unilateral non-oriental primary intrahepatic lithiasis

BACKGROUND

The current study sought to evaluate the results of liver resection as the treatment for unilateral non-oriental primary intrahepatic lithiasis (PHIL).

METHODS

Twenty-seven symptomatic patients (mean age 42 years) were submitted to liver resection; the indications were parenchymal fibrosis/atrophy in 22 and biliary stenosis in 5. Resection was associated with a Roux-en-Y hepaticojejunostomy in patients with a significant degree of dilation of the extrahepatic biliary duct.

RESULTS

There was no operative mortality and the morbidity rate was 7.4% (2 patients with biliary fistula). After a median follow-up of 41.2 months, the overall rate of good results was 92.6%. All patients submitted to liver resection alone presented good late results, while 80% of those with associated hepaticojejunostomy did not have complications (P = .12). Late complications were observed in 2 patients (7.4%): 1 with a liver abscess and 1 with cholangitis and recurrent stones. There was no mortality during long-term follow-up.

CONCLUSIONS

Liver resection showed low incidence of complications and good long-term results. None of the patients with unilateral disease without associated extrahepatic bile duct dilation presented complications and they were considered cured. We believe that resection indications should be expanded and the procedure should be indicated as routine in patients with unilateral PHIL even in the absence of parenchymal fibrosis/atrophy or biliary stenosis.

Initial experiences with laparoscopy-assisted and total laparoscopy for anatomical liver resection: a preliminary study

Although laparoscopic surgery has become more popular, its technical difficulties have limited the applications of this technique to liver surgery. We report here on our experience with liver resection with using the laparoscopy-assisted (Lap-Assist) and total laparoscopic (Total-Lap) methods. From April 2001 to June 2003, a total of 20 laparoscopic anatomical resections of the liver were retrospectively reviewed. These were comprised of 10 cases in which the Lap-Assist method was used (these were performed during the early study period), and 10 cases in which the Total-Lap was used (these were done in the later study period). In the Lap-Assist group, the following resections were performed: 7 cases of left lateral sectionectomy, a case of left hemihepatectomy, a case of right hemihepatectomy and a case of open conversion. In the Total-Lap group, 6 cases of left hemihepatectomy and 4 cases of left lateral sectionectomy were performed. The sizes of the incisions were 8.7 cm and 4.6 cm, respectively, (p=0.000). There were no differences in the operation times, the transfusion amounts, the starting days of the patients' diets, the complication rates or the durations of the hospital stay between the two groups. Both the laparoscopy-assisted method and the total laparoscopic method are feasible to use for performing anatomical liver resection.

Surgical therapy for hepatolithiasis: a Western experience

BACKGROUND

Hepatolithiasis is very common in East Asia but infrequent in Western countries, and few reports have been published in European series. In East Asia, the association between cholangiocarcinoma and hepatolithiasis is well recognized, but, on the contrary, hepatolithiasis is uncommon in Europe and the United States, and the relationship with cholangiocarcinoma is not well established. The goal of this study was to analyze the perioperative and longterm results of surgical therapy for hepatolithiasis.

STUDY DESIGN

Record review of 22 patients was done to locate immediate (operative morbidity and mortality) and longterm (stone recurrence and survival) results of patients with hepatolithiasis who underwent surgical treatment.

RESULTS

There were 19 (86.4%) hepatic resections and 10 (45.5%) hepatico-jejuno-anastomoses. Operative mortality was absent and morbidity rate was 27.3%. Right hepatectomy was predictive of postoperative complications at multivariate analysis (p = 0.04). One (4.5%) patient had an unknown associated cholangiocarcinoma at time of surgical intervention. Mean followup was 67.59 +/- 65.67 (range 12 to 215) months. None presented recurrent cholangitis during the followup period.

CONCLUSIONS

Surgical therapy is a safe and effective management for hepatolithiasis. The possibility of developing cholangiocarcinoma in inveterate hepatolithiasis is real, and hepatic resection removes this risk.

Liver transplantation for hepatolithiasis

Hepatolithiasis is frequently encountered in Asia, but is relatively uncommon in Western societies. The improved surgical and stone fragmentation techniques that have evolved over the past decade have reduced the incidence of retained or recurrent stones with a consequent reduction in progressive liver damage and cirrhosis. Nonetheless, disease-related mortality from liver failure, bleeding oesophageal varices and cholangiocarcinoma still exists and a proportion of patients are cirrhotic at their initial presentation. There have been good long-term results following liver transplantation for a variety of cholestatic liver diseases, but transplantation for hepatolithiasis has seldom been reported. This paper reports four patients who underwent successful liver transplantation for hepatolithiasis with secondary biliary cirrhosis.

Biliary cutaneous stent insertion via T-tube tract by choledochoscopy

BACKGROUND

Postoperative biliary ductal dilation and stent insertion are mandatory for managing complicated residual hepatolithiasis with intrahepatic strictures. Usually this procedure is performed under fluoroscopic guidance. Choledochoscopic examination is a routine procedure for residual hepatolithiasis. This is the first report of choledochoscopic biliary cutaneous stent insertion.

METHODS

Fifty-three patients underwent biliary cutaneous stent insertion under postoperative choledochoscopic guidance. Of the 53 patients, 35 had strictured intrahepatic ducts, 6 a stenotic hilum, 9 a tortuous fistula tract and 3 a choledochoduodenocutaneous fistula.

RESULTS

A total of 120 procedures have been performed in the 53 patients. Two thirds necessitated a repeated procedure. No major complication was found except 2 patients experienced mild abdominal pain after the procedure. Neither fluoroscopy nor contrast medium was used.

CONCLUSIONS

Choledochoscopic guidance is effective for postoperative biliary cutaneous stent insertion. It has the advantage of being technically easy and is relatively safe.

[Hepatectomy in intrahepatic lithiasis]

STUDY AIM

The aim of this study was to report the immediate results of a series of 65 hepatic resections for hepatolithiasis performed in Vietnam.

PATIENTS AND METHOD

From 1986 to 1998, 44 men and 21 women (mean age: 40 years) underwent hepatic resection for hepatolithiasis. Fourty patients had previously undergone one or several operations for hepatolithiasis. The procedure was performed on emergency in 25 patients. Indications for hepatic resection were: angiocholitis and liver abscess in 22 cases, stones closely inserted in the biliary duct in 20 cases, hemobilia in 12 cases, stones located above a biliary stricture in 8 cases and stones associated with a postoperative biliary fistula in 3 cases. Liver resections (minor in 61 patients, including 55 left lobectomies, and major in 4 patients) were performed through transhepatic approach according to the Ton That Tung technique and followed by an external biliary drainage with a Kehr tube.

RESULTS

There were 6 postoperative deaths (9%), 3 due to septic shock, 2 to cachexia, and 1 to liver failure. The 15 patients with complications recovered with conservative therapy. Bile infection was present in 93%, mostly with Escherichia coli and Enterobacter. Pigmented stones were usually found.

CONCLUSION

Vietnam is a country with high incidence of hepatolithlasis. Hepatic resection is an adequate treatment for localized intrahepatic bile duct stones when the involved segment including biliary strictures and calculi can be completely removed. The procedure may be performed on emergency for liver abscess, or hemobilia.

Peripheral cholangiocarcinoma (cholangiocellular carcinoma): clinical features, diagnosis and treatment

Peripheral cholangiocarcinoma is a relatively rare cancer. However, it is known to have an unfavourable prognosis compared with that of hepatocellular carcinoma. Little is known about its aetiology, clinical or pathological features. Recently, with the development of imaging modalities, early staged cholangiocarcinoma has been diagnosed with relative ease. Surgery is the optimal therapy. Total hepatectomy does not provide survival benefit. Conventional surgery remains the only effective treatment, even for patients with advanced-stage tumours. Factors influencing survival after hepatectomy were tumour-free margin, lymphnodes metastasis and histopathology of tumour. Palliative intrahepatic tubing or percutaneous transhepatic biliary drainage and brachytherapy can alleviate jaundice and cholangitis, thereby prolonging survival in some cases.

Comparison of treatments for hepatolithiasis: hepatic resection versus cholangioscopic lithotomy

BACKGROUND

Hepatic resection and percutaneous transhepatic cholangioscopic lithotomy (PTCSL) are the two main approaches to the treatment of hepatolithiasis, but comparisons of longterm followup results have not been adequately reported.

STUDY DESIGN

Of 86 patients with hepatolithiasis admitted to our institution between 1980 and 1996, we reviewed 54 patients: 26 who underwent hepatic resection and 28 who underwent PTCSL. Five patients who underwent postoperative cholangioscopic lithotomy were included in the former group. The remainder of the hepatolithiasis patients were not treated by hepatic resection or PTCSL and, therefore, were excluded from this study. Hepatic resections were mainly indicated for left-sided localized intrahepatic calculi, atrophic liver, and possible presence of cholangiocellular carcinoma. PTCSL was performed for right-sided, bilateral or recurrent stones at an average of 6 treatments (range 1 to 20 treatments) for each patient. There were no differences between the two groups in terms of gender or age. The recurrence rate of stones and longterm prognosis were analyzed using the Kaplan-Meier method, and other clinical factors listed below were statistically compared.

RESULTS

The rate of complete removal of stones was similarly high in each group (96.2% in the hepatic resection group versus 96.4% in the PTCSL group). The complication (38.5% versus 21.4%) and 5-year survival (85.6% versus 100%) rates were comparable. Remaining bile duct stricture (18.2% versus 60.9%, p < 0.01) and 5-year recurrence rates (5.6% versus 31.5%, p < 0.05) were statistically lower in the hepatic resection group than in the PTCSL group.

CONCLUSIONS

Hepatic resection, when combined with postoperative cholangioscopic lithotomy, is a preferable treatment for left-sided stones with strictures and bilateral stones.
