A Retrospective Study on Risk Factors Associated With Failed Endoscopic Treatment of Biliary Anastomotic Stricture After Right-Lobe Living Donor Liver Transplantation With Duct-to-Duct Anastomosis

A retrospective study was performed on 287 patients who received right-lobe living donor liver transplantation with duct-to-duct anastomosis. 

The morphology of BAS was categorized into 3 types: pouched, intermediately pouched, and triangular. 

Results: 

Fifty-nine patients (20.6%) had BAS and received ERC and balloon dilatation with or without stenting. 

The success rate was 73.2%. 

The median number of sessions needed for successful ERC was 3. 

In the 15 patients with failed ERC,
4 : percutaneous transhepatic biliary drainage and balloon dilatation, 11: hepaticojejunostomy 

Risk factors for failed ERC:
Recipient age [odds ratio (OR): 0.922; 95% confidence interval (CI): 0.85-1.00; P = 0.049], Operation time (OR: 1.007; 95% CI: 1.001-1.013; P = 0.025),
Morphology of stricture (OR: 6.722; 95% CI: 1.31-34.48; P = 0.022)

The success rates for the 3 types of BAS-pouched, intermediately pouched, and triangular-were 42.9%, 63.6%, and 88.9%, respectively (P = 0.021). Association was found between bile leak and pouched BAS (P = 0.008).

Once-Daily Extended-Release Versus Twice-Daily Standard-Release Tacrolimus in Kidney Transplant Recipients: A Systematic Review

Six randomized controlled trials (n=2499) and 15 observational studies (n=2886) were included in the review. 

Results:

No significant differences in
biopsy-proven acute rejection (two trials, n=1093; risk ratio [RR; confidence interval (CI)], 1.24 [0.93–1.65]; P=0.15; I2=0%),
patient survival
(three trials, n=1156; RR [CI], 0.99 [0.97–1.02]; P=0.55; I2=32%), and
graft survival
(three trials, n=1156; RR [CI], 0.99 [0.97–1.02]; P=0.67; I2=0%) between the two formulations at 12 months. 

Similar results for
acute rejection
(five studies, n=391; RR [CI], 0.99 [0.93–1.06]; P=0.84; I2=0%) and
overall patient survival
(two studies, n=218; RR [CI], 1.02 [0.94–1.10]; P=0.62; I2=0%) were observed in observational studies. 

Conclusions: Once-daily tacrolimus appears to be as effective as twice-daily tacrolimus up to 12 months after kidney transplantation.

De Novo Malignancies After Adult-to-Adult Living-Donor Liver Transplantation With a Malignancy Surveillance Program: Comparison With a Japanese Population-Based Study

360 adult LDLT recipients who survived more than 1 year after transplantation. 

Results: Mean follow-up period was 7.5±3.4 years.
During the follow-up period, 27 de novo malignancies were diagnosed in 26 recipients. Colorectal cancer was the most commonly detected malignancy. 

The overall mortality of the recipients with de novo malignancies was similar to the findings of the Japanese general population-based study (standardized mortality ratio=0.9). 

Overall, the incidence of cancer was significantly higher in transplant recipients than in the Japanese general population (standardized incidence ratio=1.8). 

The 5-year estimated survival rate of recipients with de novo malignancies was 81% and those of recipients without malignancies was 93% (P<0 .0001="" font="" nbsp="">

Conclusions: Colorectal malignancies predominated in Japanese liver transplant recipients. Although de novo malignancies correlated with a poor prognosis, the standardized mortality ratio was 0.9 compared with that of subjects of a Japanese population-based study.
