Gallbladder Pathologies in Kidney Transplant Recipients: Single-Center Experience and a Review of the Literature

Cholecystectomy-Associated Complications in Kidney Transplant Recipients Compared With the General Population

Cholelithiasis is one of the most prevalent diseases in the general population. Among kidney transplant (KT) recipients, atypical clinical presentation may delay the diagnosis and proper treatment. This single-center retrospective cohort study compared cholelithiasis clinical presentation and cholecystectomy-associated complications in 230 KT recipients and in 172 members of the general population. KT recipients had a higher proportion of men, comorbidities, biliary pancreatitis, choledocholithiasis, and acute cholecystitis clinical presentations than the general population. KT recipients presented higher American Society of Anesthesiologists scores and higher rates of emergency surgeries (15.7% vs 9.9%, P = .091), conversion (5.7% vs 1.2%, P = .019), drainage (7.8% vs 2.3%, P = .016), postoperative complications (10% vs 4.7%, P = .047), and longer hospital length of stay (1 vs 1 days, interquartile range, 2 vs 0 days; P < .001). There were 5 deaths, all of which occurred in KT recipients. History of diabetes mellitus, renal function, and surgical conversion were independent risk factors associated with postoperative complications. Male sex and level of renal function were independent risk factors associated with postoperative acute cholecystitis. KT was an independent risk factor associated with postoperative choledocholithiasis (adjusted odds ratio, 5.89; 95% confidence interval, 3.03-15.66) and pancreatitis (adjusted odds ratio, 6.89; 95% confidence interval, 2.99-11.61). In conclusion, KT recipients with cholelithiasis have an increased risk for clinical and surgical complications compared with the general population.

Kidney and pancreas transplant recipients undergoing cholecystectomy experience superior outcomes in transplant centers

BACKGROUND

This retrospective analysis aims to identify differences in surgical outcomes between pancreas and/or kidney transplant recipients and the general population undergoing cholecystectomy.

METHODS

Multivariate logistic regression and linear regression tests computed odds ratios (OR) and coefficients of the linear regression by analyzing weighted data from the NIS database between 2005 and 2014 to identify differences in mortality, morbidity, length of stay (LOS) and costs amongst KTx, PTx, PKTx, and non-Tx undergoing cholecystectomy in all centers and transplant centers.

RESULTS

Overall 6007 KTx, 164 PTx, 535 PKTx, and 4,207,241 non-Tx met the inclusion criteria. Mortality from cholecystectomy was 1.0%. Transplant recipients did not experience a significant increase in mortality. However KTx and PTx suffered increased morbidity risks (KTx OR1.244 p < 0.01; PTx OR2.165 p < 0.01) compared to non-Tx. However transplant recipients did not incur an increased morbidity risk in transplant centers.

CONCLUSION

Transplant recipients undergoing cholecystectomy should be counseled about their increased complication risks. Surgeons should consider transferring KTx and PTx to transplant centers for their cholecystectomy procedure to mitigate these risks.
