T-tube drainage for biliary stenosis after living donor liver transplantation

Surgical management of biliary complications following living donor liver transplantation

BACKGROUND

Biliary complications (BC) account for much of the morbidities seen after living donor liver transplantation (LDLT). Surgical reconstruction might be necessary after the failure of endoscopic or percutaneous procedures.

METHODS

  Between November 2002 and December 2009, a total of 76 LDLTs were performed. Six patients were excluded from statistical analysis because of early graft or patient loss.

RESULTS

Of 70, 26 (37.1%) developed BC; 12 (46.2%) were successfully managed by non-surgical procedures, three (11.5%) died from BC-related sepsis, one (3.8%) died from BC-unrelated causes, and 10 (38.5%) underwent surgical reconstruction. Of those 10, four patients had single duct reconstruction, five patients had double ducts reconstruction, and reconstruction was abandoned in one patient because of hepatic artery thrombosis. After a median follow-up period of 4.5 yr (0.1-6), seven (70%) remained well with no recurrent biliary problems, and three (30%) had recurrent BCs that were managed either conservatively or by retransplantation. Patients who underwent surgical reconstruction had significantly fewer hospital admissions, less need for invasive procedures, and shorter cumulative hospital stay (p < 0.05).

CONCLUSIONS

In our experience, BCs after LDLT were frequently resistant to non-surgical procedures. Surgical reconstruction is associated with fewer hospital admissions and less need for invasive procedures leading to reduced resources utilization.

Incidence and management of biliary complications after adult-to-adult living donor liver transplantation

BACKGROUND

There are few detailed reports of biliary complications in a large adult living donor liver transplantation (LDLT) series.

PATIENT AND METHODS

Biliary complications, treatment modalities, and outcomes in these patients were retrospectively analyzed in 310 adult LDLT.

RESULTS

One patient underwent retransplantation. Duct-to-duct anastomosis was primarily performed in 223 patients (72%). During the observation period (median 43 months), biliary complications were observed in 111 patients (36%); 53 patients (17%) had bile leakage, 70 patients (23%) had bile duct stenosis, and 12 patients (4%) had bile leakage followed by stenosis. A biliary anastomotic stent tube was placed in 266 patients (86%) at the time of transplantation. Univariate analysis of various clinical factors revealed duct-to-duct anastomosis as the single significant risk factor (p=0.009) for biliary complications. The three-yr and five-yr overall patient survival rates were 88% and 85% in those with biliary complications, and 85% and 83%, respectively, in those without biliary complications (p=0.59).

CONCLUSION

Biliary complications are a major cause of morbidity following LDLT. Duct-to-duct anastomosis carried a higher risk for bile duct stenosis. With appropriate management, however, there was little influence on overall survival.

Prospective evaluation of biliary reconstruction with duct-to-duct continuous suture in adult live donor liver transplantation

Purpose

Biliary reconstruction remains the Achilles’ heel of adult live donor liver transplantation (LDLT). The study aims to investigate the feasibility of duct-to-duct hepaticocholedochostomy in LDLT.

Methods

Perioperative data from 30 consecutive LDLT aiming at duct-to-duct reconstruction of the biliary tract using a continuous suture technique were prospectively collected. Nineteen recipients (63.3%) had one graft bile duct. Eleven recipients (36.7%) had two or three graft bile ducts. The median follow-up was 50 months.

Results

The overall biliary complication rate was 23.3%. Two recipients developed biliary stricture (6.7%), and two recipients (6.7%) presented with biliary leakage in early posttransplant phase (<90 days). One recipient suffered from bilioma (3.3%), and two recipients (6.7%) presented with biliary stricture in later posttransplant phase (>90 days). No correlation was found between the number of graft bile ducts and the incidence of biliary complications. No biliary complication-associated necessity for re-transplantation or mortality was observed. On multivariate analysis, no single risk factor associated with biliary complication could be identified. All biliary complications were successfully treated with Roux-en-hepaticojejunostomy and/or with endoscopic interventions.

Conclusion

Duct-to-duct hepaticocholedochostomy with continues suture represents a safe and feasible procedure for biliary reconstruction in LDLT. Recipients may benefit from aggressive management of biliary complications with Roux-en-hepaticojejunostomy as compared with repeated endoscopic interventions in early posttransplant phase.

Risk factors and prevention of biliary anastomotic complications in adult living donor liver transplantation

AIM: To evaluate risk factors of biliary anastomotic complications (BACs) and outcomes according to type of biliary reconstruction.

METHODS: A total of 33 consecutive adult living donor liver transplantation (LDLT) were reviewed, 17 of which had undergone Duct-to-Duct anastomosis (D-D). The remaining 16 patients received Roux-en-Y anastomosis (R-Y). The perioperative factors, such as the type of graft and the number of graft bile ducts, were analyzed retrospectively.

RESULTS: The overall incidence of BACs was 39.4%. The incidence of BACs was significantly higher in the patients with than without neoadjuvant chemotherapy (71.4% vs 10%, P = 0.050). There was no significant difference in the incidence of biliary leakage in patients with D-D vs those with R-Y. The incidence of biliary strictures following the healing of biliary leakage was significantly higher in D-D (60%) than in R-Y (0%) (P = 0.026). However, the incidence of BACs related bacteremia was significantly higher in R-Y than in D-D (71.4% vs 0%, P = 0.008). In D-D, use of T-tube stent remarkably reduced the incidence of BACs, compared with straight tube stent (0% vs 50%, P = 0.049).

CONCLUSION: Our experience showed an increase of BACs related bacteremia in the patients with R-Y. Therefore, D-D might be a preferred biliary reconstruction. However, the surgical refinement of D-D should be required because of the high incidence of biliary strictures. Use of the T-tube stent might lead to a significant reduction of BACs in D-D.

Liver biochemistry profile, significance and endoscopic management of biliary tract complications post orthotopic liver transplantation

AIM: To correlate the significance of liver biochemical tests in diagnosing post orthotopic liver transplantation (OLT) biliary complications and to study their profile before and after endoscopic therapy.

METHODS: Patients who developed biliary complications were analysed in detail for the clinical information, laboratory tests, treatment offered, response to it, follow up and outcomes. The profile of liver enzymes was determined. The safety, efficacy and outcomes of endoscopic retrograde cholangiography (ERC) were also analysed.

RESULTS: 40 patients required ERC for 70 biliary complications. GGT was found to be > 3 times (388.1 ± 70.9 U/mL vs 168.5 ± 34.2 U/L, P = 0.007) and SAP > 2 times (345.1 ± 59.1 U/L vs 152.7 ± 21.4 U/L, P = 0.003) the immediate post OLT values. Most frequent complication was isolated anastomotic strictures in 28 (40%). Sustained success was achieved in 26 (81%) patients.

CONCLUSION: Biliary complications still remain an important problem post OLT. SAP and GGT can be used as early, non-invasive markers for diagnosis and also to assess the adequacy of therapy. Endoscopic management is usually effective in treating the majority of these biliary complications.
