“…In the past few years, numerous comparative studies have investigated whether LESS-A presents considerable advantages over multi-port laparoendoscopic adrenalectomy (m-LA) or can be an alternative treatment option [ [13] , [14] , [15] , [16] , [17] , [18] , [19] , [20] , [21] , [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] ]. Three meta-analyses [ [36] , [37] , [38] ] compared the surgical outcomes of LESS-A and m-LA by analyzing approximately 225 cases of LESS-A and 449 cases of m-LA [ [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] , [35] ].…”
