Abstract
The presence of hepatic vascular anomalies may add challenges to an already difficult surgery such as pancreatoduodenectomy, particularly when performed laparoscopically. Thus, our aim was to assess the impact of an aberrant right hepatic artery (aRHA) on postoperative outcomes during laparoscopic pancreatoduodenectomy (LPD) . Data of patients who underwent LPD were prospectively gathered and retrospectively analyzed. Patients with types III, IV, VI, VII, VIII, and IX anomalies according to Michels’ classification were included in the aRHA group and were compared with the remaining patients (nRHA group). 72 patients underwent LPD; 14 of these had an aRHA (19.4%). Except for BMI (p = 0.021), the two groups did not differ in terms of clinico-pathological characteristics. The two groups had similar postoperative complications (p = 0.123), pancreatic fistula (p = 0.790), biliary leakage (p = 0.209), postpancreatectomy hemorrhage (p = 0.790), reoperations (p = 0.416), and mortality (p = 0.312). The median number of lymph nodes harvested was higher in aRHA group (p = 0.032), while R0 resection rate was similar between groups (p = 0.635). At the multivariate analysis, only moderate/high FRS (OR 3.95, p = 0.039) was an independent predictor of postoperative complications. This study suggests that aRHA has no negative impact on surgical and oncological outcomes in patients undergoing LPD.
