30 April 2013	Amended	Two publications (a full text article and a conference abstract) may be two different randomised trials. We did not receive a reply from the authors on our e‐mail sent in February 2007 and July 2013. Only one of the reports contain information that can be used for analysis. So, whether these are two reports of the same trial or two different trials does not affect the meta‐analysis in any way. For the purpose of this review, we considered them to be two reports of the same trial.
26 February 2013	New citation required and conclusions have changed	Conclusions partially changed. In the previous version of the review, we did not recommend abdominal wall lift over pneumoperitoneum but mentioned that it was probably safe. While we continue to recommend that abdominal wall lift cannot be preferred over pneumoperitoneum in those at low anaesthetic risk, we have revised our conclusion regarding the safety. We now believe that the safety of abdominal wall lift has not been established and so should be considered only in the trial setting. Our conclusions have been revised from the previous version of the review (Gurusamy 2008) because of the updated version of the Cochrane Handbook for Systematic Reviews of Interventions (Higgins 2011), which has resulted in a better understanding of the interpretation of evidence..
19 February 2013	New search has been performed	Searches were updated on 19 of February 2013. No new trials were found. The reference flow was changed due to the updated searches, trial sequential analyses were revised, and the funder who provided funding for the update of this review is now acknowledged.
