Are outcomes good enough? A systematic review and meta-analysisis of observational studies. PG - 183-189 LID - S0009-739X(20)30277-3 [pii] LID - 10.1016/j.ciresp.2020.08.009 [doi] AB - INTRODUCTION: Efficacy of the ligation of intersphincteric fistula tract (LIFT) procedure for posterior fistula-in-ano remains under debate. However, there is scarcity of quality evidence analysing this issue. Thus, the aim of this study is to evaluate outcomes of LIFT surgery in patients with posterior anal fistula. MATERIAL AND METHODS: Systematic review and meta-analysis to evaluate efficacy of LIFT procedure for posterior anal fistula. MEDLINE (PubMed), EMBASE, Scopus, Web of Science, Cochrane Library and Google Scholar data sources were searched for key-words (MeSH terms): "LIFT" OR "Ligation of the intersphincteric fistula tract" AND "posterior anal fistula" OR "posterior fistula-in-ano". Original, observational and experimental, non-language restriction studies published from January 2000 to March 2020 and reporting outcomes on LIFT procedure for posterior anal fistula were reviewed. Quality and potential biases were assessed using Newcastle-Ottawa scale, following AHRQ recommendations. Additional sensitivity analysis and publication bias evaluation (Beg and Egger's tets) were performed. RESULTS: No significant differences were found in recurrence rate among patients undergoing LIFT procedure for posterior fistula-in-ano in contrast to other locations (OR 1.36 [IC 95% 0.60-3.07]; p=.46). I(2) test value was 77%, expressing a fair heterogeneity among included studies. The weighed median for overall recurrence was 37.8% (RI 18.3-47.7%); with a weighed median of 47.1% (RI 30.7 - 63.7%) and 36.3% (RI 15.8-51.3%) (p=.436) respectively for recurrence after LIFT for posterior fistula and fistula in other locations. There was not clear evidence about the sample size ("n") of included studies nor the disparities in quality assessment of those, could justify the observed heterogeneity. No significant publication bias was found. CONCLUSION: This systematic review and meta-analysis suggests that there are no clear data in the literature for not performing the LIFT procedure in posteriorly located fistulas.
