This updated review used an expanded search strategy, updated Risk of Bias assessment, and updated inclusion criteria. These changes resulted in inclusion of 10 additional studies compared with the initial review (n = 363 additional participants; one study compared LASB to a placebo/inert treatment [Aydemir 2006], the remaining nine studies compared LASB with an active treatment [Bonelli 1983; Carroll 2009; Meier 2009; Nascimento 2010; Raja 1991; Rodriguez 2005; Toshniwal 2012; Wehnert 2002; Zeng 2003]). Despite these methodological updates and inclusion of new studies, the conclusions of the review remain unchanged; there is a dearth of published evidence for LASB and the available evidence suggests lack of efficacy. Readers of the original review would benefit from reading this update as new evidence is provided for treatment comparisons between LASB and other active interventions (for example, intravenous nerve blocks).
