Posthepatectomy bile leakage: how to manage.
TL;DR: The incidence of posthepatectomy biliary leakage has decreased over time, while PTD and endoscopic stenting are effective treatment modalities.
Abstract: Background: Biliary leakage after liver resection continues to be reported. Management of bile leakage has changed in recent years, with nowadays non-surgical procedures as the preferred treatment. Methods: Biliary leakage and management were assessed in 381 patients who underwent liver resection between January 2005 and April 2011. Results: The overall rate of biliary leakage after liver resection was 5.0%, with a higher incidence in patients who had undergone concomitant hepaticojejunostomy (HJ; 13.6 vs. 3.2%). Hospital stay (p = 0.047), major resections (p = 0.018), operation time (p = 0.011), and relaparotomy (p = 0.002) were risk factors for postoperative bile leakage. Multivariate analysis identified relaparotomy as an independent factor (OR 4.216, p = 0.034). Bile leakage in patients without HJ (n = 10) was managed in 6 patients by percutaneous transhepatic biliary drainage (PTD), and in 3 patients by endoscopic drainage. One patient was treated surgically. All patients with an HJ and postoperative bile leakage (n = 9) underwent PTD. Conclusion: The incidence of posthepatectomy biliary leakage has decreased over time, while PTD and endoscopic stenting are effective treatment modalities. PTD is the treatment of choice in bile leakage after resection combined with HJ.

TL;DR: Patients with nondilated intrahepatic bile ducts who underwent a PTBD procedure for the treatment of bile leakage between January 2000 and August 2012 were retrospectively assessed and PTBD was an effective treatment with low complication rates.
Abstract: Objective and Background: Bile leakage is a serious postoperative complication and percutaneous transhepatic biliary drainage (PTBD) may be an option when endoscopic treatment is not feasible. In this retrospective study, we established technical and clinical success rates as well as the complication rates of PTBD in a large group of patients with postoperative bile leakage. Methods: Data on all patients with nondilated intrahepatic bile ducts who underwent a PTBD procedure for the treatment of bile leakage between January 2000 and August 2012 were retrospectively assessed. Data included type of surgery, site of bile leak, previous attempts of bile leak repair, interval between surgery and PTBD placement. Outcome measures were the technical and clinical success rates, the procedure-related complications, and mortality rate. Results: A total of 63 patients were identified; PTBD placement was technically successful in 90.5% (57/63) after one to three attempts. The clinical success rate was 69.8% (44/63). Four major complications were documented (4/63; 6.3%): liver laceration, pneumothorax, pleural empyema, and prolonged hemobilia. One minor complication involved pain. Conclusions: PTBD is an effective treatment with low complication rates for the management of postsurgical bile leaks in patients with nondilated bile ducts.

TL;DR: Risk-adjusted BMVs are likely much more applicable and appropriate in assessing "acceptable" benchmark outcomes following liver surgery as well as other factors influence the risk of complications following hepatectomy.
Abstract: Background The best achievable short-term outcomes after liver surgery have not been identified. Several factors may influence the post-operative course of patients undergoing hepatectomy increasing the risk of post-operative complications. We sought to identify risk-adjusted benchmark values [BMV] for liver surgery. Methods The National Surgery Quality Improvement Program (NSQIP) database was used to develop Bayesian models to estimate risk-adjusted BMVs for overall and liver related (post-hepatectomy liver failure [PHLF], biliary leakage [BL]) complications. A separate international multi-institutional database was used to validate the risk-adjusted BMVs. Results Among the 11,243 patients included in the NSQIP database, the incidence of complications, PHLF, and BL was 36%, 5%, and 8%, respectively. The risk-adjusted BMVs for complication (range, 16–72%), PHLF (range, 1%–20%), and BL (range, 4%–22%) demonstrated a high variability based on patients characteristics. When tested using an international database including nine institutes, the risk-adjusted BMVs for complications ranged from 26% (Institute-4) to 43% (Institute-1), BMVs for PHLF between 3% (Institute-3) and 12% (Institute-5), while BMVs for BL ranged between 5% (Institute-4) and 9% (Institute-7). Conclusions Multiple factors influence the risk of complications following hepatectomy. Risk-adjusted BMVs are likely much more applicable and appropriate in assessing “acceptable” benchmark outcomes following liver surgery.

TL;DR: The multivariate regression analysis revealed that preoperative chemotherapy, major hepatectomy and biliodigestive reconstruction remained significant independent risk factors for bile leaks.
Abstract: Background: Bile leaks are one of the most common complications after liver resection. The International Study Group of Liver Surgery (ISGLS) established a uniform bile leak definition including a severity grading. However, a risk factor assessment according to ISGLS grading as well as the clinical implications has not been studied sufficiently so far.
Methods: The incidence and grading of bile leaks according to ISGLS were prospectively documented in 501 consecutive liver resections between July 2012 and December 2016. A multivariate regression analysis was performed for risk factor assessment. Association with other surgical complications, 90-day mortality as well as length of hospital stay (LOS) was studied.
Results: The total rate of bile leaks in this cohort was 14.0%: 2.8% grade A, 8.0% grade B, and 3.2% grade C bile leaks were observed. Preoperative chemotherapy or biliary intervention, diagnosis of hilar cholangiocarcinoma, colorectal metastasis, central minor liver resection, major hepatectomy, extended hepatectomy or two-stage hepatectomy, were some of the risk factors leading to bile leaks. The multivariate regression analysis revealed that preoperative chemotherapy, major hepatectomy and biliodigestive reconstruction remained significant independent risk factors for bile leaks. Grade C bile leaks were associated not only with surgical site infection, but also with an increased 90-day mortality and prolonged LOS. Conclusions: The preoperative treatment as well as the surgical procedure had significant influence on the incidence and the severity of bile leaks. Grade C bile leaks were clinically most relevant, and led to significant increased LOS, rate of infection, and mortality.

TL;DR: After LMH, BL occurred in 13.5 % of the patients and was associated with significant morbidity, and patients with one or several risk factors for BL should benefit intra-operative drain placement.
Abstract: Bile leakage (BL) remains a common cause of major morbidity after open major liver resection but has only been poorly described in patients undergoing laparoscopic major hepatectomy (LMH). The present study aimed to determine the incidence, risk factors and consequences of BL following LMH. All 223 patients undergoing LMH between 2000 and 2013 at two tertiary referral centres were retrospectively analysed. BL was defined according to the International Study Group of Liver Surgery, and its incidence and consequences were assessed. Risk factors for BL were determined on multivariate analysis. BL occurred in 30 (13.5 %) patients, and its incidence remained stable over time (p = 0.200). BL was diagnosed following the presence of bile into the abdominal drain in 14 (46.7 %) patients and after drainage of symptomatic abdominal collections in 16 (53.3 %) patients without intra-operative drain placement. Grade A, B and C BL occurred in 3 (10.0 %), 23 (76.6 %) and 4 (13.4 %) cases, respectively. Interventional procedures for BL included endoscopic retrograde cholangiography, percutaneous and surgical drainage in 10 (33.3 %), 23 (76.7 %) and 4 (13.3 %) patients, respectively. BL was associated with significantly increased rates of symptomatic pleural effusion (30.0 vs. 11.4 %, p = 0.006), multiorgan failure (13.3 vs. 3.6 %, p = 0.022), postoperative death (10.0 vs. 1.6 %, p = 0.008) and prolonged hospital stay (18 vs. 8 days, p 28 kg/m2 (OR 2.439, 95 % CI 1.878–2.771, p = 0.036), history of hepatectomy (OR 1.675, 95 % CI 1.256–2.035, p = 0.044) and biliary reconstruction (OR 1.975, 95 % CI 1.452–2.371, p = 0.039) were significantly associated with increased risk of BL. After LMH, BL occurred in 13.5 % of the patients and was associated with significant morbidity. Patients with one or several risk factors for BL should benefit intra-operative drain placement.

TL;DR: In this paper, the authors defined postoperative bile leakage as continuous drainage with a bilirubin concentration of 20 mg/dL or 1,500 mg/d lasting 2 days.
Abstract: Background Bile leakage is one of the frequent and disturbing complications of hepatic resection. Study design Clinical records of the 363 patients who underwent hepatic resections without biliary reconstruction for hepatic cancers between January 1994 and June 2001 were reviewed. Postoperative bile leakage was defined as continuous drainage with a bilirubin concentration of 20 mg/dL or 1,500 mg/d lasting 2 days. Leakage that continued longer than 2 weeks or that required surgical intervention was defined as uncontrollable. Differences in incidence and frequency of uncontrollable leakage for the different types of hepatic resection, tumors, and underlying liver disease were investigated. Outcomes after treatment for uncontrollable bile leakage were also reviewed. Results Postoperative bile leakage occurred in 26 of 363 patients (7.2%). Although the incidence in patients with cholangiocellular carcinoma (3/9 [33%]) was higher (p = 0.03) than in patients with hepatocellular carcinoma, rates of occurrence were similar among the different types of hepatic resection and underlying liver disease. Eight of the 26 patients (31%) had uncontrollable leakage. Two patients required reoperation to control leakage; one of these developed hepatic failure and died 2 months after surgery. Four patients underwent endoscopic nasobiliary drainage 21 to 34 days after hepatectomy, and the leakage resolved within 3 to 21 days. Fibrin glue sealing was effective in two patients whose leaking bile ducts were not connected to the common bile duct. Conclusions Although meticulous surgical technique can minimize the risk of postoperative bile leakage, some instances of leakage are unavoidable. Nonsurgical treatments, such as nasobiliary drainage or fibrin glue sealing, are preferable to reoperation.

TL;DR: The aim of this study was to evaluate the incidence of anastomotic leak after intrahepatic cholangiojejunostomy and to identify risk factors for such leakage.
Abstract: Background:
Although intrahepatic cholangiojejunostomy is technically difficult, with recent improvements in surgery it should be possible to perform the anastomosis safely. The aim of this study was to evaluate the incidence of anastomotic leak after intrahepatic cholangiojejunostomy and to identify risk factors for such leakage.
Methods:
Intrahepatic cholangiojejunostomy was performed in 423 patients undergoing hepatobiliary resection between January 1991 and December 2005. Anastomotic leak was proven radiographically by leakage from the anastomosis of contrast medium introduced via a biliary drainage tube placed during surgery.
Results:
Anastomotic leak occurred in 27 patients (6·4 per cent), and was not related to the number of bile ducts reconstructed. The leak rate decreased significantly from 9·5 per cent (19 of 199) in the first 10 years to 3·6 per cent (eight of 224) in the last 5 years. Anastomotic leak was often followed by infections such as wound infection, intra-abdominal abscess and bacteraemia. Multivariable analysis identified age and intraoperative blood loss as independent risk factors for anastomotic leak. All leaks were treated by maintaining a prophylactically placed drain near the cholangiojejunostomy; neither repeat laparotomy nor percutaneous transhepatic biliary drainage was required.
Conclusion:
Although demanding, intrahepatic cholangiojejunostomy can be performed successfully with a relatively low failure rate. Routine use of prophylactic drains and anastomotic stenting allows safe management of anastomotic leak with conservative therapy. Copyright © 2006 British Journal of Surgery Society Ltd.

TL;DR: More meticulous management is needed to prevent bile leakage in high-risk patients, and three independent factors were identified that were significantly correlated with the occurrence of biles leakage.
Abstract: Bile leakage is the most common complication after hepatectomy and its incidence is not declining. The aim of the present study was to identify predictive factors for bile leakage. Clinical data from 505 consecutive patients who underwent hepatectomy without extrahepatic bile duct resection in our department between January 2006 and December 2009 were reviewed retrospectively. The incidence of bile leakage was found to be 6.7%. Multivariate analysis identified three independent factors that were significantly correlated with the occurrence of bile leakage: (1) repeat hepatectomy (P = 0.002; odds ratio [OR] 3.439; 95% confidence interval [CI] 1.552–7.618), (2) a cut surface area ≥57.5 cm2 (P = 0.004; OR 5.296; 95% CI 1.721–16.302), and (3) intraoperative blood loss ≥775 ml (P = 0.01; OR 2.808; 95% CI 1.280–6.160). More meticulous management is needed to prevent bile leakage in high-risk patients.
