Despite the accumulation of favorable results from laparoscopic liver resection (LLR), centrally located tumors close to the hilum, major hepatic veins, or inferior vena cava (IVC) are still considered contraindications for LLR. We evaluated the feasibility and safety of LLR for centrally located tumors. ⋯ This study shows that LLR can be safely performed in selected patients with centrally located tumors close to the liver hilum, the major hepatic veins, or the IVC that were previously considered to be contraindications for LLR. Recent technical developments in the performance of laparoscopic major liver resection may have contributed to the successful application of LLR for centrally located tumors.

We demonstrated previously that ischemic postconditioning (IPo) attenuated intestinal injury induced by intestinal ischemia/reperfusion (I/R), and thereafter employed a proteomic method to identify aldose reductase (AR), a differentially expressed protein in intestinal mucosal tissue, which was downregulated by intestinal I/R and upregulated by IPo. This study aimed to further explore the possible role of AR in intestinal protection conferred by IPo. ⋯ These findings suggest that IPo attenuates intestinal I/R-induced intestinal injury via AR-mediated oxidative defense and apoptosis suppression; AR inhibition reverses the protective effects of IPo. AR seems to be an innate protective factor in this model of intestinal I/R.
