目的 研究完全腹膜外腹腔镜腹股沟疝修补术对睾丸血流灌注及体积的影响。 方法 2009年7月－2011年5月，对62例行完全腹膜外腹腔镜单侧腹股沟疝修补术男性患者进行自身前后对照研究，比较术前、术后患侧睾丸的睾丸动脉（TA）、睾丸包膜动脉（CA）、睾丸内动脉（ITA）血流参数[收缩期峰值血流速度（PSV）、舒张未期血流速度（EDV）及血管阻力指数（RI）]、睾丸体积（TV）及血清睾酮的变化情况。 结果 患者获随访7～24个月，平均15.6个月，无复发患者。术前及术后3、6个月时患侧TV分别为（9.91 ± 3.72）、（10.23 ± 4.18）和（10.16 ± 3.94）cm3，同期血浆睾酮水平分别为（544.25 ± 123.72）、（532.89 ± 145.66）和（565.65 ± 138.13）μg/L，手术前后比较患侧TV（F=1.350，P=0.263）、血浆睾酮水平（F=1.673，P=0.192）无统计学意义，血浆睾酮水平均在正常范围内。术后3、6个月患侧TA、CA和ITA的EDV明显高于术前，RI较术前明显降低，差异均有统计学意义（P＜0.05）；PSV与术前比较差异无统计学意义（P＞0.05）。术后3个月患侧睾丸各动脉PSV、EDV、RI与术后6个月比较差异无统计学意义（P＞0.05）。 结论 完全腹膜外腹腔镜腹股沟疝修补术后患侧睾丸血流灌注情况可能会有所改善，不影响TV及血清睾酮水平。
Objective To evaluate the clinical experience and skills of laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a balloon dissection in order to spread and popularize this kind of operation. Methods Under general anesthesia, 32 patients (42 sides) with inguinal hernias were repaired by laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a dissection balloon from August 2005 to December 2007. Results All of operations were successfully performed. The operative time was 60-120 minutes, the blood loss was 20-60 ml, and the length of postoperative hospitalization was 3 days. All cases were followed up for 8 to 18 months and found no recurrence. Conclusion Laparoscopic totally extraperitoneal hernia repair with non-stapling of mesh and without using a balloon dissection is feasible, reliable and effective, offering a low recurrence rate, while its price is higher than tension-free herniorrhaphy by traditional method.
【Abstract】Objective To investigate the effects of tension-free herniorrhaphy on endocrine functions of patients with inguinal hernia. MethodsOne hundred and twenty-seven patients were randomly divided into tension-free group(n=65) and conventional group (n=62). The mean ages of tension-free group and conventional group were(51.8±14) year and(48.4±12) year respectively. There were 52 indirect hernias and 13 direct hernias in tension-free group. There were 51 indirect hernias and 11 direct hernias in conventional group. Bassini repair was used in conventional group. Peripheral blood samples were obtained preoperatively and 3 h, 24 h after operation for measuring the levels of cortisol, T3, TSH, insuline, Cpeptide and and glucose. The data were analysed through t test. ResultsThe levels of cortisol, C-peptide and glucose in conventional group were remarkably higher (P6”0.05) while the levels of T3,TSH were notably lower (P＜0.05) than those in tension-free group at 3 h, 24 h postoperatively, the level of insulin in conventional group was significantly higher than that in tension-free group at 24 h postoperatively. ConclusionThe results of this study indicate that tension-free repair imposes less influence on the endocrine functions of patients with inguinal hernia postoperatively than conventional repair does. This might explain pathophysiologically the quick recovery of the patients receiving tension-free herniorrhaphy.

Objective To explore the application effect of 3D printed heart models in the training of young cardiac surgeons, and evaluate their application value in surgical simulation and skill improvement. MethodsEight young cardiac surgeons were selected form West China Hospital as the trainees. Before training, the Hands-On Surgical Training-Congenital Heart Surgery (HOST-CHS) operation scores of the 8 cardiac surgeons were obtained after operating on 2 pig heart models of ventricular septal defect (VSD). Subsequently, simulation training was conducted on a 3D printed peri-membrane VSD heart model for 6 weeks, once a week. After the training, all trainees completed 2 pig heart VSD repair surgeries. The improvement of doctors’ skills was evaluated through survey questionnaires, HOST-CHS scores, and operation time after training. ResultsBefore the training, the average HOST-CHS score of the 8 trainees was 52.2±6.3 points, and the average time for VSD repair was 54.7±7.1 min. During the 6-week simulation training using 3D printed models, the total score of HOST-CHS for the 8 trainees gradually increased (P<0.001), and the time required to complete VSD repair was shortened (P<0.001). The trainees had the most significant improvement in scores of surgical cognition and protective awareness. The survey results showed that trainees were generally very satisfied with the effectiveness of 3D model simulation training. Conclusion The 3D printed VSD model demonstrates significant application advantages in the training of young cardiac surgeons. By providing highly realistic anatomical structures, 3D models can effectively enhance surgeons’ surgical skills. It is suggested to further promote the application of 3D printing technology in medical education, providing strong support for cultivating high-quality cardiac surgeons.
ObjectiveTo observe the pathological changes of the peritoneum before and after the total extraperitoneal herniorrhaphy via preperitoneal space approach for incisional hernia in rats, and to explore the effects on the ischemia and necrosis of the peritoneum and its function after the extensive dissociation of the preperitoneal space and the implantation of the patch. MethodsA total of 80 SD rats were randomly divided into normal control group (n=8), hernia model control group (n=8), patch implantation blank control group, and hernia model patch repair group. Eight rats were randomly selected at week 1, 4, 8, and 12 after patch implantation from the patch implantation blank control group and hernia model patch repair group. The normal peritoneum and surrounding tissues were taken from the normal control group, and the peritoneal tissues near the incision were taken from the hernia model control group, patch implantation blank control group, and the hernia model patch repair group. The hematoxylin-eosin staining was performed to observe the pathological changes of the peritoneum. The degrees of inflammatory cell infiltration and fiber hyperplasia among the different groups were compared. Results① Comparison of the degree of inflammatory cell infiltration in the peritoneal tissue, which in the patch implantation blank control group at week 1 and 4 after patch implantation was more severe than the normal control group (P＜0.001, P=0.005) respectively, which at week 8 after patch implantation was alleviated (P=0.021) as compared to the 1st week after patch implantation in the patch implantation blank control group, which had no statistic difference between the patch implantation blank control group and normal control group (P=0.102), which at the 1st week after patch implantation was more severe than hernia model control group (P=0.014), which was alleviated at week 8 and 12 after patch implantation as compared to the 1st week after patch implantation in the hernia model patch repair group (P=0.040, P=0.040), which had no statistic differences between the patch implantation blank control group and the hernia model patch repair group at same time point after patch implantation (P>0.05). ② Comparison of the degree of fiber hyperplasia in the peritoneal tissue, which at week 1, 4, and 12 after patch implantation was more severe (P＜0.001, P=0.003, P＜0.001, respectively) in the patch implantation blank control group as compared with the normal control group; which was alleviated at week 8 after patch implantation as compared to the 1st week after patch implantation in the hernia model patch repair group（P=0.017); which was more severe in the hernia model control group as compared with the normal control group (P=0.012); which had no statistical differences between the hernia model control group and the hernia model patch repair group at different time point (P>0.05); which had no obvious change between-time point in the hernia model patch repair group (P>0.05); which had no statistic differences between the patch implantation blank control group and the hernia model patch repair group at same time point after patch implantation (P>0.05). ConclusionsBased on the experimental results of this study, hernia itself will not stimulate inflammatory cell infiltration and fiber hyperplasia of peritoneal tissue. However, during the process of total extraperitoneal herniorrhaphy via preperitoneal space approach, extensive peritoneal space dissociation and patch implantation will cause peritoneal injury and affect its function. But through the body itself repair, the function caused by peritoneal injury can be fully restored to normal status on the 8th week after patch implantation.
