It is recognised that one of the major difficulties in performing laparoscopic surgery is the translation of two-dimensional video image information to a three-dimensional working area. However, research has tended to ignore the gaze and eye-hand coordination strategies employed by laparoscopic surgeons as they attempt to overcome these perceptual constraints. This study sought to examine if measures related to tool movements, gaze strategy, and eye-hand coordination (the quiet eye) differentiate between experienced and novice operators performing a two-handed manoeuvres task on a virtual reality laparoscopic surgical simulator (LAP Mentor™). ⋯ The findings of the study provide further support for the utility of examining strategic gaze behaviour and eye-hand coordination measures to help further our understanding of how experienced surgeons attempt to overcome the perceptual difficulties inherent in the laparoscopic environment.

Recent population survey has shown a preference for transumbilical laparoendoscopic single-site surgery (U-LESS) compared with natural orifice transluminal endoscopic surgery (NOTES) for cholecystectomy, assuming similar surgical risk. This study was designed to evaluate the perception and preference of women regarding conventional laparoscopy, U-LESS, and transvaginal NOTES (TV-NOTES) with particular interest to access perception. ⋯ The high acceptation rate for U-LESS approach compared with TV-NOTES may be related to fears regarding postoperative sexuality and fertility. The importance of temporary postoperative sexual abstinence (vaginal intercourse) is high and may be difficult to influence. Future research on TV-NOTES should focus on the access risk to be able to scientifically reassure our patients. For now, U-LESS seems to be favor compared with TV-NOTES for cholecystectomy in female patients.

Peripheral subpleural solitary pulmonary nodules can be visualized and resected easily at thoracoscopy, but it is very difficult to localize deep nonpalpable pulmonary nodules that lie in lung parenchyma. The purpose of this article was to study the effectiveness of video-assisted thoracoscopic solitary pulmonary nodules resection after computed tomography (CT)-guided hookwire localization and to review the literature related to solitary pulmonary nodule diagnosis and treatment. ⋯ Video-assisted thoracoscopic solitary pulmonary nodule resection after CT-guided hookwire localization is a safe and effective procedure for accurate diagnosis and resection of indeterminate solitary pulmonary nodules.

Conventional laparoscopic and robot-assisted spleen-preserving pancreatectomy: does da Vinci have clinical advantages?
Function-preserving minimally invasive pancreatectomy is thought to be an ideal approach for pancreatic benign and borderline malignant lesions requiring pancreatectomy. However, it is not that easy to accomplish this goal with the conventional laparoscopic approach. It requires extensive surgeon experience and learned techniques. A robot surgical system was recently introduced to overcome these limitations and it may potentially provide precise and safe laparoscopic surgery. ⋯ Robot-assisted pancreatic surgery could provide an increased chance for spleen preservation in spite of higher cost and longer operation time. More experiences are needed to specifically address the role of robot surgery in the advanced laparoscopic era.

Safe surgical care requires effective information transfer between members of the operating room (OR) team. The present study aims to assess directly, systematically, and comprehensively, information needs of all OR team-members. ⋯ This study comprehensively maps information sources, problems, and solutions expressed by OR end-users. Recent developments in skills training modules and patient safety interventions for the OR (Surgical Safety Checklist) are discussed as potential interventions that will ameliorate communication in ORs, with a view to enhance patient safety and surgical care.
