title: Histopathologic Findings of Cholecystectomy Specimens in Patients Who Underwent Donor Hepatectomy for Living Donor Liver Transplantation.
abstract: BACKGROUND
  The aim of this study was to discuss the macroscopic and microscopic properties of gallbladder specimens obtained from living liver donors.
  
  
  METHODS
  The study retrospectively analyzed the clinical and histopathological data of 1088 donors who underwent living donor hepatectomy between March 2005 and September 2014 at Inonu University Faculty of Medicine, Liver Transplantation Center. Age, sex, macroscopic, and microscopic properties of the gallbladder (bladder length, diameter, content, and histopathological properties) were recorded by 2 researchers.
  
  
  RESULTS
  A total of 1009 donors aged 17 to 66 years (31.1 ± 9.5) met the inclusion criteria, whereas 79 donors were excluded due to missing data. In total, 587 donors were male (30.5 ± 9.1 years [16-63 years]) and 422 were female (31.8 ± 9.8 years [18-66 years]). Preoperative tests revealed Gilbert syndrome in 3 subjects, whereas other donors' biochemical tests were within normal ranges. The macroscopic examination of gallbladders revealed mean gallbladder wall thickness, length, and width of 1.82 ± 0.8 mm (1-10 mm), 72 ± 11.4 mm (40-120 mm), and 52.5 ± 14 mm (15-90 mm), respectively. The microscopic gallbladder examination showed that 740 donors had a normal gallbladder, 193 had chronic cholecystitis (1 donor had antral metaplasia and 1 had intestinal metaplasia), 40 had cholesterolosis (1 donor had both tubular adenoma and intestinal metaplasia), 15 had minimal chronic cholecystitis (1 donor had pyloric metaplasia), 14 had cholelithiasis, 2 had adenomyosis, 2 had muscular hypertrophy, 1 had papillary hyperplasia, 1 had microdiverticulitis, and 1 had mucosal lymphatic ectasia.
  
  
  CONCLUSIONS
  The results of this study reflect the actual gallbladder pathologies that can be detected in healthy people. Clearer conclusions can be reached about the epidemiological data on gallbladder as the number of living liver donors increases in the future.
