Use of methylene blue and a spring microcoil in the preoperative localization of small pulmonary nodules under CT guidance: a meta-analysis.

ABSTRACT:

Objective

Methylene blue (MB) and spring microcoils are used for the preoperative localization of small pulmonary nodules (SPNs). We aimed to compare the efficacy and safety of these methods using published data.

Methods

We identified randomized controlled trials and observational studies that assessed preoperative SPN localization using MB or spring microcoil and compared these using a meta-analysis.

Results

Seven studies of 933 patients were identified, in whom 1081 SPNs were located. Four hundred twenty-four SPNs were located using MB (n = 359 participants), and 657 SPNs were located using the spring microcoil method (n = 574 participants). The prevalence of technical success of SPN localization was higher using MB (mean deviation [MD]: 0.43; 95% confidence interva
