Partial segments 4/5 liver resection facilitates the repair of complicated bile duct injuries: a technical challenge and long-term outcomes.

Adequate exposure with optimal anteroposterior view of the hilar plate is challenging and crucial in a surgical repair of complicated hilar bile duct injuries. A high-quality anastomosis depends on the ability to identify non-scarred, non-inflamed, non-ischemic bile ducts. This study provides operative details of the Partial Segments 4/5 Liver Resection with a Roux-en-Y hepaticojejunostomy (PS4/5LRHJ) and presents its long-term outcomes. 36 patients with the Strasberg type E bile duct injuries (BDIs) who underwent the PS4/5LRHJ from 2003 to 2019 were retrospectively reviewed. Outcomes of the surgical treatments were analyzed. The mean age of the patients was 46.3 years. 22 patients underwent BDI repair as index operations and 14 patients as re-repair operations. Operative times between the index operation group and the re-repair group (396.6 min vs 391.3 min, respectively, p = 0.876) and blood loss (590.6 ml vs 640 ml, respectively, p = 0.587) were not statistically different. The mean length of hospital stay was 23 days. The median follow-up duration was 73 months. Major complications developed in 10 patients (27.8%), of which intra-abdominal collection was the most common (eight patients, 22.2%). Anastomotic stricture developed in one patient (2.8%). The mortality rate was zero. The overall 10-year patency rate was 95.2%. PS4/5LRHJ offered long-term patency with acceptable morbidity in the hilar bile duct injuries and re-repair operations.
