The significance of hepatectomy for primary intrahepatic stones

Biliary exploration via the left hepatic duct orifice versus the common bile duct in left-sided hepatolithiasis patients with a history of biliary tract surgery: A randomized controlled trial

BACKGROUND

Hepatectomy and additional common bile duct exploration are required for the treatment of left-sided hepatolithiasis (LSH).

METHODS

Eligible LSH patients (n = 62) scheduled for open left lateral segmentectomy or left hemihepatectomy with intraoperative biliary exploration via the left hepatic duct orifice (LHD group, n = 35) or the common bile duct (CBD group, n = 27) were retrospectively studied. T-tube insertion was performed on selected patients. Primary outcome measures included overall operative time, length of hospital stay, intraoperative complications, residual stones, and postoperative bile leaks.

RESULTS

There were no residual stones observed in the 2 groups. Ten patients in the CBD group received T-tube placement, whereas no patients in the LHD group received T-tube placement. There were more patients in the CBD group suffered intraoperative complications and postoperative bile leakage than LHD group (P < .05). The LHD group had a significantly shorter operative time and hospitalization than the CBD group (P < .05).

CONCLUSION

For left-sided hepatolithiasis patients with a history of biliary tract surgery, LHD cholangioscopy is an accessible technique that simplifies the operation procedure by avoiding choledochotomy and subsequent T-tube insertion, which results in lower complication rates as well as shorter operative duration and length of hospitalization.

Left-sided hepatic resection for hepatolithiasis: a longitudinal study of 110 patients

BACKGROUND

Hepatolithiasis affecting the left hepatobiliary system is common in the Asia Pacific region. This aim of this study was to describe an experience with the diagnosis and treatment of patients with isolated left-sided hepatolithiasis.

METHODS

One hundred and ten patients with isolated left-sided hepatolithiasis who underwent a left-sided hepatic resection between January 1999 and February 2010 were included for further analysis. The clinical profile, cholangiograms, operative procedures and early and late results were examined.

RESULTS

Analysis of magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP) findings revealed left hepatic ductal anatomical details in 101 patients. Three types of left hepatic ductal variations were observed (type 1 in 90.1%, type 2 in 5.9% and type 3 in 4.0% patients). Eighty-four (76.4%) patients had the presence of strictures in the left hepatic ductal system and in 26 (23.6%) patients no strictures could be seen. Out of 84 patients with strictures, 78 could be classified (type I in 89.7% and type II in 10.3%). Of the 110 patients, 75 (68.2%) underwent a left lateral sectionectomy, 33 (30%) a left hepatectomy and 2 (1.8%) patients were treated with a left hepatectomy combined with a caudate lobe resection. Of the patients who underwent a left hepatectomy 11.4% developed a bile leak. Eight per cent of patients who underwent a left lateral sectionectomy had infective complications. During a median follow-up period of 63 (range 3-134) months, 2 (2.1%) patients were discovered to have residual stones and five (5.2%) others possessed recurrent stones.

CONCLUSIONS

This study highlights the impact of the presence or absence of bile duct stricture on the clinical and histological profile of patients as well as their operative and the post-operative behaviour. It is concluded that hepatic resection is an appropriate treatment modality in localized left-sided hepatolithiasis.

Liver resection for intrahepatic stones in congenital bile duct dilatation

OBJECTIVE

This study reports our clinical experience with liver resection for congenital dilatation of the intrahepatic bile duct and intrahepatic gallstones to evaluate results and define indications for treatment.

PATIENTS AND METHODS

We studied the clinical data of patients who underwent hepatic resection for intrahepatic lithiasis from January 1992 to December 2008 and assessed the immediate and long-term results of these interventions.

RESULTS

Of 49 treated patients, 47 underwent liver resection. In the majority of cases, the disease was limited to the left lobe and left hepatectomy was the most commonly performed surgical procedure. The operative mortality was zero with morbidity in 24.5% of patients. Cholangiocarcinoma was diagnosed in six cases (12.2%). In 91.6% of cases the long-term results were good or satisfactory.

CONCLUSION

Treatment goals in all cases should be the elimination of intrahepatic stones, the prevention of recurrent lithiasis, and prevention or cure of cholangiocarcinoma. Surgical excision is the best possible treatment for symptomatic patients with localized disease and atrophy of the affected liver.

Intraoperative biliary exploration through the left hepatic duct orifice during left hepatectomy in patients with left-sided hepatolithiasis

BACKGROUND AND AIMS

Left-sided hepatolithiasis often requires left hepatectomy and exploration of the common bile duct and right hepatic duct. The aim of this study was to assess the feasibility of alternative method of bile duct exploration other than choledochotomy.

MATERIALS AND METHODS

A prospective study involving 50 cases of left hepatectomy for left or bilateral intrahepatic stone was performed. Left hepatic duct (LHD) orifice was used as primary access route for biliary exploration. Choledochotomy was performed only for large common bile duct stones, variant bile duct anatomy, or intentional T-tube insertion for later removal of residual stones.

RESULTS

In 44 patients with left-sided hepatolithiasis, biliary exploration through LHD orifice was performed in 40 (90.9%); T-tube choledochotomy was required in three (9.1%). There was neither residual stone nor major surgical complication except infection, and recurrence occurred in one patient during mean follow-up of 32 months. On the other hand, T-tube choledochotomy was performed in three of six patients with bilateral hepatolithiasis (50%). Three patients had residual stones, and two of them were treated by cholangioscopy through the T-tube tract. Recurrence occurred in two patients.

CONCLUSION

We think that intraoperative biliary exploration through LHD orifice in left-sided hepatolithiasis patients is an effective approach simplifying the operation procedure by avoiding choledochotomy and subsequent T-tube insertion.
