No-touch resection of hilar malignancies with right hepatectomy and routine portal reconstruction.
OBJECTIVE
Locoregional recurrence following resection of hilar biliary cancers could be caused by the microscopic dissemination of cancer cells during dissection of the portal vein from the involved bile duct at the hilar region. This retrospective study assessed the feasibility and safety of a new procedure consisting of right-sided hepatectomy, caudate lobectomy, and bile duct resection combined with routine resection of the portal bifurcation to enable no-touch resection of hilar malignancies.


METHODS
Of 64 patients who underwent right-sided hepatectomy for hilar biliary cancer, the portal bifurcation was routinely resected by the above new procedure in 25 patients, based on preoperative imaging diagnoses. Perioperative outcomes were compared with those in patients who underwent conventional portal reconstruction (n = 18) and with those in patients who had preservation of the portal bifurcation (n = 21).


RESULTS
Perioperative data from patients with routine portal reconstruction were similar to those in the patients with conventional portal reconstruction and the patients without portal reconstruction. There were no postoperative complications directly related to portal reconstruction.


CONCLUSIONS
No-touch resection of hilar malignancies with right hepatectomy and the routine use of portal reconstruction was feasible and safe. The oncologic impact of this technique merits further evaluation.
