LETTERS TO THE EDITORSingle-port Cholecystectomy and Quality of LifeMichael CottonPublished online: 14 August 2013 Socie´te´ Internationale de Chirurgie 2013I was intrigued by the article by Wagner et al. [1] in theMay 2013 issue of the World Journal of Surgery. Theauthors’ conclusions, inter alia, state that single-port cho-lecystectomy results in a better quality of life (QoL) score.This is based on a survey of the 222 patients in the study.Information on QoL is garnered from 131 completedquestionnaires. This figure represents 59 % (not 69 %) ofthe patients. Thus, 91 did not reply or gave inadequateinformation. This figure is sufficiently large to make theconclusion based on the remaining questionnaires dubiousat best.Furthermore, single-port access (SPA) cholecystectomywas performed by consultant surgeons, whereas the stan-dard laparoscopic approach was used by several surgeonsof varying experience, including those below consultantstatus. The SPA procedure took longer even though per-formed by senior surgeons. Presumably, if performed byless experienced operators, it would logically take evenlonger and therefore prove even more expensive. Thus, twoplanks of the conclusion in the aforesaid article areremoved. It therefore appears to be in danger of tottering.Reference1.
