Duct-to-Duct Biliary Anastomosis Yields Similar Outcomes to Roux-en-Y Hepaticojejunostomy in Liver Transplantation for Primary Sclerosing Cholangitis
Bibliographic record
Abstract
BACKGROUND: While Roux-en-Y hepaticojejunostomy (RYH) is the common anastomotic technique for liver transplantation (LT) in patients with primary sclerosing cholangitis (PSC), duct-to-duct (DD) reconstruction may be used if the recipient common bile duct is normal. There are conflicting observational data on the rate of success of DD reconstruction versus RYH, in PSC. OBJECTIVES: The aim of this study was to assess the safety and efficacy of DD anastomosis, compared to RYH reconstruction, among adults transplanted for PSC. PATIENTS AND METHODS: All adult patients, who underwent primary LT for PSC between 1990 and 2012, were evaluated, according to type of biliary reconstruction. Recipient and graft survival, postoperative medical and surgical complications, and postoperative resource utilization rates were compared between the two groups. RESULTS: Totally, 73 patients fulfilled the inclusion criteria. Of them, 58 had RYH and 15 had DD reconstruction. A total of 53 subjects (73%) were male, with the mean age ± standard deviation at LT of 43.3 ± 14.4 years. Rates of recipient mortality, graft failure, biliary complications, acute cellular rejection, and reoperation were similar in both groups. Postoperative cholangiography was used more frequently in patients with DD reconstruction (33.3% vs. 8.6%, P = 0.026). CONCLUSIONS: In selected recipients with PSC, DD reconstruction is a safe and efficacious technique, with long-term clinical outcomes comparable to RYH.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
