Backgrounds:
This study aimed to determine whether the Mayo adhesive probability score (MAP), which evaluated adherent perinephric fat (APF), is useful in evaluating the difficulty of retroperitoneal laparoscopic adrenalectomy (RLA), and to analyse the correlation between MAP and perioperative parameters.
Methods:
Clinical data of 104 patients with adrenal adenoma who underwent RLA were collected for retrospective analysis. According to the CT images obtained before surgery, patients were divided into two groups: High MAP group (2-5 points) and Low MAP group (0-1 points). Comparison of the general clinical characteristics and the perioperative data between the two groups was made.
Results:
There were more male patients (73.7% versus 34.3%), more patients with a smoking history (24.3% versus 7.5%), higher BMI (25.7 versus 23.2, kg/m2 ), and bigger (23.8 versus 18.5, mm) neoplasm in the high MAP group (P < 0.05). Significant difference was observed in operative time (128.8 versus 102.3, min), estimated blood loss (47.2 versus 25.2, ml) and drainage tube removal time (4.0 versus 3.2, d) between the two groups (P < 0.05). A high MAP score (P < 0.001) and the size of tumour (P = 0.024) were independent risk factors for extended operative time. A higher BMI (OR = 1.525, P < 0.001) and larger tumour size (OR = 2.862, P = 0.004) were independent risk factors for a high MAP score.
Conclusions:
MAP score was associated with the perioperative outcomes of RLA. BMI and tumour size were better indicators of MAP score, which can influence the difficulty of RLA.
