 note = {Single-port laparoscopic surgery（SPLS）has attracted attention in the field of minimally invasive surgery; however, the associated technical difficulty has delayed its adoption by all surgeons. Reduced-port laparoscopic surgery might be easier to perform than SPLS, and in this prospective study, we compared surgeon stress and workload between reduced-port laparoscopic cholecystectomy（RPLC）and conventional laparoscopic cholecystectomy（CLC）. Twenty consecutive patients were assigned to undergo either RPLC or CLC between July 2016 and April 2017. Two surgeons performed the operations. The differences in surgeon workload and stress between RPLC and CLC were evaluated. Patient factors and operative outcomes were not significantly different between RPLC and CLC. In the surgeon-reported Surgery Task Load Index, the task demand subscale was significantly higher for RPLC than for CLC（P＝0.005）, although the salivary amylase levels were not significantly different between RPLC and CLC. RPLC was similar to CLC with respect to surgeon stress. Considering workload, the task demand was higher in CLC than in RPLC, which therefore might be an acceptable alternative to CLC for treating benign gallbladder disease.},
