Abstract:Abstract:ObjectiveTo compare the efficacy and safety of transsphenoidal surgery(TSS) and transcranial surgery(TCS) for the treatment of pituitary abscess(PA).MethodsLiteratures related to TSS and TC for PA were searched by computer from PubMed, Embase, the Cochrane library, CBM, CNKI, VIP, Wanfang upto Jan 2020. The indexes included clinical cure, symptom improvement, complications and longterm recurrence rate. RevMan 5.3 software was used to analyze the extracted data.ResultsEleven studies with a total of 154 samples were included, Of all the cases, 125 were treated with TSS and 29 with TCS. Analyses revealed that there was no significant difference in the postoperative effect[RR=1.25,95%CI(0.90~1.74), P=0.19]between TSS and TCS, with significant reduction of postoperative complications[RR=0.18, 95%CI(0.07~0.46), P<0.001]and recurrence[RR=0.38, 95%CI(0.21~0.68), P=0.001] in TSS.ConclusionCompared with TCS, TSS has no difference in efficacy for the treatment of PA, but it can significantly reduce the risks of postoperative complication and recurrence.
