Biliary Complications in Live Donor Liver Transplantation
Condition: Biliary Stricture; Bile Duct Stenosi; Bile Leak; Bile Duct Injury
MeSH terms: Constriction, Pathologic
Study type: Observational [Patient Registry]

Summary: 
      The study was designed as a prospective cohort study. The effects of hot and cold ischemic
      times during live donor liver transplantation on postoperative 1-3 and 6 month follow up
      biliary complications will be investigated.
    

Detailed description: 
      The invastigators will record the age, gender, weight, diagnosis, presence of hcc
      (hepatocellular carcinoma), whether transcatheter embolization (transarterial
      radiolabelization) is performed, meld score, age of donor, gender, graft hepatic artery
      diameter, bile duct diameter and number before surgery.

      During the operation,

      The duration of ischemia will be evaluated as three stages.

      During the first stage donor hepatectomy, the time from the interruption of the hepatic
      artery to the first administration of the solution to the bile ducts on the back table will
      be recorded and recorded as the first ischemia time.

      The time from the administration of the solution to the biliary system on the stage 2
      back-to-back table until the cold anastomosis is performed will be recorded as the duration
      of cold ischemia.

      The time from the third graft to receipt of the graft to the end of the hepatic artery
      anastomosis will be recorded as the second ischemia time.

      The duration of operation, whether or not pringle maneuvers were performed, hepatic artery
      thrombus, graft bile number, number of bile anastomoses, lowest biliary tract diameter and
      hepatic artery diameter

      After the surgery,

      The use of immunosuppression (Tacrolimus, certican or combined use) will be recorded.

      During the follow-up period of 1,3,6 months, complaints of the patients, laboratory values
      and imaging methods as well as whether or not there is biliary complication (leakage,
      stenosis) will be recorded.

      If the complication develops during follow-up, the procedure (follow-up, ercp, ptk, surgery)
      will be recorded.

      Since the study is observational, normal treatment will not be involved.

      Participants will not be included in the study in the presence of hepaticojejunostomy
      patients, cadaveric transplant patients, pediatric transplant patients, Cmv infection,
      hepatic artery thrombosis, portal thrombosis, acute rejection in the first operation.

      Participants with live donor liver transplant patients, multiple gallbladder anastomoses or
      single bile duct multiple anastomoses will be included.

      When the power analysis for the study was taken as α = 0.05 and 1-β (power) = 0,80, it was
      calculated that at least 99 patients should be taken to have a difference of 38% in the rates
      of biliary complication in cold ischemia.

      The demographic and all findings of the disease will be collected at excell and at the end of
      the study all the findings will be statistically evaluated and the results will be evaluated.
