Comparative Study
Comparison of two models for the prediction of nonsentinel node metastases in breast cancer.
It is debated whether all patients with a positive sentinel node dissection (SLND) should be submitted to axillary lymph node dissection (ALND). Models have been developed to estimate the likelihood of nonsentinel node (non-SLN) metastases. ⋯ The MSKCC nomogram can help individualize the surgical treatment of SLN-positive breast cancer when the likelihood of further axillary involvement is low or surgical risks are higher.

Although laparoscopic splenectomy has become the preferred treatment of choice for hematologic-related splenic disorders, intraoperative blood loss remains a common occurrence. In an effort to reduce this risk, we evaluate the potential role and clinical outcome of concomitant intraoperative splenic artery embolization and laparoscopic splenectomy. ⋯ Concomitant splenic artery embolization and laparoscopic splenic reduced operative blood loss when compared with laparoscopic splenectomy procedure alone. Splenic artery embolization is a useful intraoperative adjunctive procedure that should be considered in patients undergoing laparoscopic splenectomy for hematologic disorders who are Jehovah's Witness or with significant hypersplenism because of benefit of reduced blood loss.

Very few studies have addressed the transferability of skills from virtual reality (VR) to real life. The aim of this study was to assess the feasibility and effectiveness of teaching intracorporeal knot tying (ICKT) by VR simulation only. ⋯ Teaching ICKT by VR simulators only is feasible and effective. Furthermore, this study highlights the complementary use of different VR simulators within a structured curriculum.

Tempol (Sigma-Aldrich, Steinheim, Germany) is a stable piperidine nitroxide of low molecular weight that permeates biologic membranes and scavenges superoxide anions in vitro. In recent animal studies, the delaying effect of intraperitoneal sepsis on the healing of colonic anastomoses has been shown. In this study we aimed to investigate the effects of Tempol on the healing of colonic anastomoses in the presence of polymicrobial sepsis. ⋯ This study showed that Tempol treatment significantly prevented the delaying effect of CLP-induced polymicrobial sepsis on anastomotic healing in the left colon. Further clinical studies are needed to clarify whether Tempol may be a useful therapeutic agent to increase the safety of the anastomosis during particular surgeries in which sepsis-induced organ injury occurs.
