Can the mayo adhesive probability score predict perioperative outcomes in laparoscopic total and partial adrenalectomy?

Abstract

Objective: This study aimed to determine whether the Mayo adhesive probability (MAP) score could predict perioperative outcomes in transperitoneal laparoscopic total adrenalectomy (LTA) and laparoscopic partial adrenalectomy (LPA). Materials and Methods: The clinical data of 139 patients who underwent transperitoneal LTA (n = 116) or LPA (n = 23) between March 2013 and September 2022 were retrospectively analyzed. According to the images obtained from preoperative contrast-enhanced computed tomography or magnetic resonance imaging, the patients were divided into two groups: the low MAP score group (0-1 points) and the high MAP score group (2-5 points). General clinical features and perioperative outcomes were compared between the groups. Results: In patients with a high MAP score, the mean body mass index (BMI) ( p: 0.005), tumor size ( p: 0.005), operative time ( p: 0.002), estimated blood loss (EBL) ( p: 0.001), and complication rate ( p: 0.013) were significantly higher compared with those with a low MAP score. The comparison of the patients between the LTA and LPA subgroups revealed that operative time and EBL were significantly higher in both subgroups among the patients with a high MAP score. Moreover, the complication rate in the LTA subgroup was significantly higher in the high MAP score group compared with the other group. The Multivariate analyses revealed that a high MAP score was a risk factor for prolonged operative time (Odds Ratio [OR]: 3.081, 95% Confidence Interval [CI]: 1.284-7.398, p: 0.012), increased EBL (OR: 2.495, 95% CI: 1.114-5.588, p: 0.026), and complications (OR: 6.085, 95% CI: 1.532-24.171, p: 0.01) Conclusions: Patients with a high MAP score had a prolonged operative time, increased EBL, and a higher complication rate compared with those with a low MAP score. In addition, we found that a high MAP score was an independent risk factor for perioperative parameters and complications in patients who underwent LTA and LPA.
