- Abstract
Background: To examine the impact of the Mayo adhesive probability (MAP) score on the surgical complexity of exposing the tumor during laparoscopic partial nephrectomy (LPN). Patients and Methods: Our study included 318 patients who underwent LPN from January 2017 to December 2018 at our institution. Patients were divided into a lower MAP score group (≤2, n = 172) and a higher MAP score group (≥3, n = 146). Perioperative outcomes were compared between the groups. The operative time was predominantly occupied by the dissection time and the warm ischemia time (WIT). Results: A higher MAP score was associated with a longer operative time (131 vs 110 minutes, p < 0.001) and longer dissection time (71 vs 54 minutes, p < 0.001), respectively. The estimated blood loss (EBL) increased in patients with a higher MAP score (50 vs 20 mL, p < 0.001). No significant difference was found with respect to the WIT (21 vs 20 minutes, p = 0.370). In the multivariate linear regression model, male gender (β = 11.199, p = 0.001), body mass index (β = 1.197, p = 0.008), and MAP score (β = 9.958, p = 0.002) were significantly associated with the prolongation of dissection time. Conclusions: The MAP score was significantly associated with the prolongation of dissection time during LPN. In addition, the EBL increased in patients with a higher MAP score. Therefore, the MAP score can predict surgical complexity of exposing the tumor in patients undergoing LPN.
