Management of Biliary Complications in Liver Transplant Recipients with Duct-To-Duct Anastomosis: A Single-Center Experience

BACKGROUND

The aims of this study were to investigate biliary complications in liver transplant recipients with choledochocholedocho stomy anastomosis, to identify the risk factors for the development of such complications, and to evaluate the success of endoscopic approaches in liver transplant recipients.

METHODS

Between January 2013 and May 2021, a total of 238 patients with liver diseases underwent liver transplantation: 174 recipients undergoing choledochocholedochostomy anastomosis were included in the analysis.

RESULTS

Their median age was 54.0 years. The median posttransplant follow-up period was 29 months. Hepatitis B virus infection (33%) was the most common indication for liver transplantation. Most patients (87%) received living donor liver transplantation. The overall prevalence of posttransplant biliary complications was 31%. Anastomotic biliary strictures were the most common biliary complications (72%), followed by biliary leakage (13%). The median time between endoscopic retrograde cholangiography and liver transplantation was 4 months, with a mean of 3 ± 1.6 sessions. Endoscopic retrograde cholangiography-guided drainage and balloon dilation with or without stent placement was the most common treatment modalities for recipients with biliary strictures. The overall success rate of endoscopic treatment modalities was 83.3%, with 65% of the recipients exhibiting complete biochemical and endoscopic responses. The response did not differ significantly between living donor liver transplantation and cadaveric donor liver transplant recipients (P > .05). Three recipients required revision surgery for biliary complication repair. Six patients died due to biliary sepsis.

CONCLUSION

Biliary stricture and leakages were the most common biliary complications after liver transplantation. Endoscopic treatment was successful in most recipients.

Phagocytic activity in familial Mediterranean fever

Familial Mediterranean fever (FMF) is an autosomal recessive disease. Although the possibility of multiple immunologic mechanisms have been studied, the actual mechanism is still unresolved. Forty-one patients with FMF (24 males and 17 females with a mean age and disease duration of 17.8 +/- 4.1 and 4.7 +/- 2.3 years, respectively) and 14 healthy controls (10 males and 4 females with a mean age 23.2 +/- 5.1) were involved in the study. A phagotest was studied in both the patients and control groups with a FACScalibur Flow. All patients were in the acute stages of the disease and had not undergone colchicine treatment for 2 months. The percentage blood phagocytic activity of both granulocytes and monocytes were 84.23 +/- 8.76 and 67.28 +/- 10.15 in the patient group and 94.68 +/- 3.24 and 76.23 +/- 5.7 in the control group, respectively. There was no statistically significant difference in the percentage of phagocytic activity of the granulocytes and monocytes between the FMF patients and healthy controls (p > 0.05 and p > 0.05, respectively).
