Several months after the publication of the article entitled, “Long-Term Outcomes of Hepatectomy for Bilateral Hepatolithiasis with Three-Dimensional Reconstruction: A Propensity Score Matching Analysis” by Guan T, Fang C, Mo Z, Xiang N, Yang J, Zeng N. (J Laparoendosc Adv Surg Tech A. 2016;26(9):680–688. DOI: 10.1089/lap.2016.0165; PMID: 27420918), the lead author of the paper, Tianpei Guan, contacted the Editor of the Journal and requested a formal retraction of the article as the authors now believe that they used the wrong statistical methods and are concerned that the results might be inconclusive or wrong. Dr. Guan also stated— post-publication—that some of the patients underwent conventional hepatectomy in a different department than their own, and therefore, could present a potential conflict of interest.
After careful consideration of Dr. Guan's request, the Editor-in-Chief of Journal of Laparoscopic and Advanced Surgical Techniques agreed to officially retract the article from the literature based on these concerns.
