Animal model-based simulation training for three emergent and urgent operations of penetrating thoracic injuries.

PURPOSE: To develop animal models of penetrating thoracic injuries and to observe the effects of the animal model-based training on improving the trainees' performance for emergent and urgent thoracic surgeries. METHODS: With a homemade machine, animal models of lung injuries and penetrating heart injuries were produced in porcine and used for training of chest tube drainage, urgent sternotomy, and emergent thoracotomy. Coefficient of variation of abbreviated injury scale and blood loss was calculated to judge the reproducibility of animal models. Five operation teams from basic-level hospitals (group A) and five operation teams from level III hospitals (group B) were included to be trained and tested. Testing standards for the operations were established after thorough literature review, and expert questionnaires were employed to evaluate the scientificity and feasibility of the testing standards. Tests were carried out after the training. Pre- and post-training performances were compared. Post-training survey using 7-point Likert scale was taken to evaluate the feelings of the trainees to these training approaches. RESULTS: Animal models of the three kinds of penetrating chest injuries were successfully established and the coefficient of variation of abbreviated injury scale and blood loss were all less than 25%. After literature review, testing standards were established, and expert questionnaire results showed that the scientific score was 7.30 ± 1.49, and the feasibility score was 7.50 ± 0.89. Post-training performance was significantly higher in both group A and group B than pre-training performance. Post-training survey showed that all the trainees felt confident in applying the operations and were generally agreed that the training procedure were very helpful in improving operation skills for thoracic penetrating injury. CONCLUSIONS: Animal model-based simulation training established in the current study could improve the trainees' performance for emergent and urgent thoracic surgeries, especially of the surgical teams from basic-level hospitals.

OBJECTIVE: To analyze the results of minimally invasive surgical treatment of patients with urgent colon diseases. MATERIAL AND METHODS: There were 89 patients with urgent colon diseases. All patients were divided into 2 groups: the main group - 31 patients who underwent laparoscopic surgeries, the control group - 58 patients operated via open access. Both groups were comparable by age and underlying disease. However, significant differences in gender, severity of comorbidities and complications of the underlying disease were observed. RESULTS: Surgery time, postoperative morbidity (9.7% vs. 6.9%) and postoperative hospital-stay were similar in both groups. Quality of life was significantly better in the main group compared with the control group if colostomy was absent. In case of stoma, there were no between-group differences. CONCLUSION: Laparoscopic surgery is associated with reduced need for analgesics, similar duration of intervention and postoperative morbidity. Complete restoration of quality of life in these patients is observed in 6 months after surgery. Colostomy results similar quality of life after laparoscopic and open surgery.

The current trends in the treatment of various surgical diseases of large bowel using minimally invasive operations are reviewed in the manuscript. It is shown that laparoscopy is currently possible in most cases for urgent large bowel diseases.
