ABSTRACT
We investigated the outcomes of pancreaticoduodenectomy in the presence of an aberrant right hepatic artery (aRHA). We systematically reviewed Medline, Scopus, and Web of Science until April 2023 for studies comparing pancreaticoduodenectomy outcomes with and without aRHA. Endpoints included postoperative mortality, R0 resection margins, pancreatic fistulae, hemorrhage, biliary leak/fistulae, delayed gastric emptying, operative duration, and blood loss. Eight retrospective studies involving 1514 patients were included. The risk ratio (RR) for postoperative mortality and odds ratio (OR) for R0 resection between the aRHA and normal anatomy groups were 1.37 (95%CI:0.74-256) (I2=0%, P=0.99) and 1.03 (95%CI:0.67-1.59) (I2=10%, P=0.35). Besides a longer operative duration in the aRHA group, mean difference (MD) 54.64 (95% CI: 8.51-100.77) (I2=94%, P<0.01), there were no significant differences in secondary endpoints. Meta-regression revealed a significant association between aRHA reconstruction and postoperative mortality (β=0.0179, P<0.01). This review displayed non-statistically significant differences in terms of surgical and oncological outcomes between patients with aRHA and patients with normal hepatic artery anatomy undergoing pancreaticoduodenectomy. However, the observed trend of increased postoperative mortality in patients with aRHA, combined with extended surgical duration and the link between aRHA reconstruction and postoperative mortality, prevents drawing definitive conclusions. Further research through high-quality studies is warranted.
