Impact of bile duct number and anastomosis technique on postoperative morbidity and mortality in living and deceased donor liver transplantation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Objective: This study aims to retrospectively examine the relationship between graft bile duct number (single or multiple) and biliary anastomosis technique (duct-to-duct or Roux-en-Y hepaticojejunostomy) with postoperative morbidity and mortality in living donor liver transplantation (LDLT) and deceased donor liver transplantation (DDLT) patients. Material and Methods: A retrospective cohort study was conducted on 244 patients who underwent LDLT and DDLT at Ankara Güven Hospital Liver Transplantation Center between January 2013 and January 2025. Patient data including demographic characteristics, preoperative parameters (MELD score, underlying liver disease), surgical variables (bile duct number, anastomosis type, graft type, operation time), and postoperative outcomes were collected systematically. Bile duct anatomy was classified as single or multiple ducts, and anastomosis techniques were categorized as duct-to-duct or Roux-en-Y. Biliary complications were graded according to the International Liver Transplant Society consensus classification and Clavien-Dindo system. Statistical analyses were performed using SPSS 27.0, employing independent-samples t-tests, Mann-Whitney U tests, and chi-square tests. Results: The mean patient age was 57.8±11.5 years with mean body mass index (BMI) of 27.62±5.67 kg/m². The cohort comprised 70.49% males and 29.51% females. Significant gender distribution differences were observed between groups, with higher male ratio in the duct-to-duct group (75.94%) compared to Roux-en-Y group (63.96%; p=0.041). Diabetes mellitus prevalence was notably higher in the Roux-en-Y group (46.85%) versus duct-to-duct group (34.59%; p=0.052). No significant differences were found in age, BMI, or blood group distribution between anastomosis techniques. Conclusion: Preliminary findings suggest demographic and comorbidity variations between anastomosis technique groups, indicating the need for individualized surgical planning in LDLT and DDLT based on bile duct anatomy and patient characteristics.
