[Surgical errors in acute diseases of the abdominal cavity organs].

Case histories of dead patients were analyzed in whose life-time errors were made in diagnosis of acute abdomen. It was established that in 90 patients acute abdomen was hypodiagnozed, in 10 cases the abdominal catastrophe was hyperdiagnozed, in 4 patients the localization of the injured organ was not determined properly. The error found mainly resulted from atypical course of the disease due to age of the patients, medication effects and abnormal disposition of the injured organ, as well as to concomitant diseases and complications. The role of the attention factor in the genesis of errors is emphasized.

[Need for randomizing microvascular surgical experiments for testing new prosthesis material, with special reference to personal surgical errors from a morphological viewpoint].

In the examination of material involving two microvascular prostheses of different nature the need is discussed of randomising experimental series to achieve a self-critical control of operative dexterity in microsurgical techniques and to exclude eventual errors arising and influencing the results. A comparison was made of two polyurethane prostheses, one porous (n = 15), and the other covered internally with a smooth silicon layer (n = 15). They were implanted using microsurgical techniques into the infrarenal portion of the abdominal aorta in rats. The main criterion for successful implantation was a patency over a prolonged period of observation lasting a maximum of 407 days. The porous prosthesis showed the best results. Most frequent complications were early thrombosis and technical faults demonstrated by histology. Therefore, the distribution through prospective randomisation of good and bad results based on technical errors enhances the significance of material analysis.

Diagnostic errors in surgical pathology.

This article discusses the concept of diagnostic error in surgical pathology and how surgical pathologists attempt to decrease diagnostic error. Emphasis is placed on currently used error reduction methods.

Measuring and reporting errors in surgical pathology. Lessons from gynecologic cytology.

Substantial improvements in measuring and reporting errors in gynecologic cytology have been made during the last decade. Measuring and reporting errors in surgical pathology recently has gained renewed interest. However, review of current literature demonstrates mistakes in how these data are measured and reported. Error rates have been reported from review of consecutive material, biopsy material, and consultation material and range from 0.25% to 43%. Errors have been divided into anatomic regions and specimen types and separated according to their clinical significance. However, to be comparable, errors must be reported in reference to the incidence of disease and not to overall caseload. Blinding and reviewer error have been addressed only rarely, and the true incidence of errors is almost certainly higher than reported. "Gold standards" are not well defined. In addition, available data strongly suggest that the greatest source of error is with false-negative diagnoses, which are detected only rarely by review of consultation material. Most of these issues have been addressed in the gynecologic cytology literature. Errors in surgical pathology are more common than generally believed, and efforts should be made to define methods that allow appropriate interlaboratory comparisons.

The value of virtual reality-simulator training in the development of laparoscopic surgical skills.

OBJECTIVE: To determine the effectiveness of virtual reality (VR) training in improving the surgical skills of medical students and gynecologic trainees. DESIGN: A prospective observational study to assess the changes observed in objectively measured surgical performance after VR training. SETTING AND POPULATION: University teaching hospital and the laboratories of the University of Western Australia. PARTICIPANTS: Fifteen 5th-year medical students, six junior-doctor trainees (years 1-3), and eight senior trainees (years 4-6). INTERVENTIONS: Standard gynecologic procedures before and after VR training were undertaken on sheep. The procedures were video-recorded and edited to blind the scorer as to identity and seniority of the operator. The procedures were scored using a combination of operative time and penalties for surgical errors. The surgical scores were correlated with the VR scores. MEASUREMENTS AND MAIN RESULTS: Operative skills were assessed using a combination score compiled from scores obtained while undertaking salpingectomy, salpingotomy, and tubal clipping. Virtual reality scores were also a combination score derived from summation of various computer-calculated measures of time and accuracy in undertaking two standardized exercises. RESULTS: The baseline VR scores were significantly related to the overall pre-training scores (salpingectomy p = .032). A better initial VR score was also predictive of better surgical performance. The initial VR score was also predictive of improvement observed between baseline and post-training (p = .004). CONCLUSION: Virtual reality training is of value in improving surgical skills in the clinical environment. It appears to be of most value in the earliest stages of training. These data suggest that serious consideration should be given to incorporating VR training into the training program of obstetricians and gynecologists at an early stage.
