In minimally invasive surgery (MIS), a surgeon needs to acquire a certain level of basic psychomotor MIS skills to perform surgery safely. Evaluation of those skills is a major impediment. Although various assessment methods have been introduced, none of them came as a superior. Three aspects of assessing psychomotor MIS skills are discussed here: (i) advantages and disadvantages of currently available assessment methods, (ii) methods to objectively classify residents according to their level of psychomotor skills, and (iii) factors that influence psychomotor MIS skills. Motion analysis has a potential to be the means to deal with assessment of psychomotor skills. Together with classification methods (e.g. linear discriminant analysis), motion analysis provides an aid in deciding whether a resident is ready to move to the next level of training. Presence of factors that influence psychomotor MIS skills results in a high need for standardisation of valid tasks and setups used for the assessment of MIS skills. [ABSTRACT FROM AUTHOR]

Objective. A case series is presented to illustrate the dilemma in management of women with Chronic Pelvic Pain (CPP) additional to a tubal sterilization. Methods. Between January 1999 and June 2007, five women consulted the Department of Gynecology for CPP additional to tubal sterilization with Filshie Clips (FCs). A biopsychosocial approach of the complaint was offered and laparoscopic removal of the clips was performed in all cases. The effectiveness of this management was assessed by a personal interview and a retrospective chart review. Results. Two of the five patients refused an exploration of psychosocial factors possibly contributing to or maintaining the pain. During laparoscopic removal of the Filshie Clips no additional pathology was noted. At follow-up four women declared to have benefited from the removal procedure. Conclusion. If women present with CPP additional to sterilization with FCs in the absence of obvious pathology, gynecologists have to pay attention to the possibility of underlying psychosocial factors to this complaint. However, this attention can be in conflict with the woman's conviction that only removal of the clips will alleviate her pain. In that case, laparoscopic removal might be a component of the management. [ABSTRACT FROM AUTHOR]

The aim of this study was to evaluate the catheterisation regimes after a laparoscopic hysterectomy (LH) in Dutch hospitals and to assess the nurses' opinion on this topic. This was particularly relevant as no consensus exists on the best moment to remove a urinary catheter after an LH. All 89 Dutch hospitals were successfully contacted and provided information on their catheterisation regime after LH: 69 (77.5%) hospitals reported removing the catheter the next morning after the LH, while nine hospitals (10.1%) removed it directly at the end of the procedure. The other 11 hospitals had different policies (four hours, up to two days). Additionally, all nurses working in the gynaecology departments of the hospitals affiliated to Leiden University were asked to fill in a self-developed questionnaire. Of the 111 nurses who completed the questionnaire (response rate 81%), 90% was convinced that a direct removal was feasible and 78% would recommend it to a family member or friend. Impact Statement What is already known on this subject? Although an indwelling catheter is routinely placed during a hysterectomy, it is unclear what the best moment is to remove it after an LH specifically. To fully benefit from the advantages associated with this minimally invasive approach, postoperative catheter management, should be, amongst others, optimal and LH-specific. A few studies have demonstrated that the direct removal of urinary catheter after an uncomplicated LH is feasible, but the evidence is limited. What the results of this study add? While waiting for the results of the randomised trials, this present study provides insight into the nationwide catheterisation management after an LH. Despite the lack of consensus on the topic, catheterisation management was quite uniform in the Netherlands: most Dutch hospitals removed the urinary catheter one day after an LH. Yet, this was not in line with the opinion of the surveyed nurses, as the majority would recommend a direct removal. This is interesting as nurses are closely involved in the patients' postoperative care. What are the implications of these findings for clinical practice and/or further research? Although randomised trials are necessary to determine an optimal catheterisation management, the findings of this present study are valuable if a new urinary catheter regime has to be implemented.

With the emphasis on laparoscopic skills training outside of the operating room (OR), simulators are constantly being developed and improved. Virtual reality (VR) trainers have been looking for solutions to compensate their lack of haptic feedback. A possible solution is the addition of kinematic interaction between laparoscopic instruments and objects. The aim of the study was to determine whether this interaction can replace haptic feedback that is naturally present in box trainers. Novices (n == 50) were randomly assigned to training in a conventional VR setup (VR-I), a VR environment with additional kinematic interaction (VR-II), a box trainer equivalent of these setups (Box-I or Box-II), or to a control group. An identical cylinder task was performed in all four training setups. The effect was established by comparing the performance before and after training during a tissue handling task, using Wilcoxon signed-rank tests. The controls did not improve significantly. The VR-I group improved in time, whereas VR-II and both box trainer groups improved in time, path length and motion in depth. With respect to haptic feedback, box training models are superior to VR systems. However, additional kinematic interaction between instruments and objects can be a promising surrogate for haptic feedback in VR systems. [ABSTRACT FROM AUTHOR]
