Objective: To evaluate the clinical effect of transabdominal preperitoneal laparoscopic hernia repair in the treatment of incarcerated inguinal hernia. Methods: Retrospective analysis was done with the clinical data of 44 patients of incarcerated inguinal hernia enrolled and operated in our hospital from January 2015 to December 2019. Twenty-four cases in study group were treated with transabdominal preperitoneal laparoscopic hernia repair and 20 cases undergoing Lichtenstein surgery in control group. Operative time, the time of first postoperative off-bed activities, postoperative hospital stay, pain score of first postoperative day, total hospital cost were compared between two groups. Follow-up was done for 12 months and postoperative seroma, incision infection, mesh infection, and recurrence were compared between two groups. Results: Operative time and total hospital cost in study group were higher than those in control group，(80.96±13.25) min vs. (64.90±18.80) min (P0.05). Conclusions: Transabdominal preperitoneal laparoscopic hernia repair in the treatment of incarcerated inguinal hernia had longer operative time and higher cost, but with the advantages of less pain and faster recovery after surgery.

Detection of tiny object in complex environments is a matter of urgency, not only because of the high real-world demand, but also the high deployment and real-time requirements. Although many current single-stage algorithms have good detection performance under low computing power requirements, there are still significant challenges such as distinguishing the background from object features and extracting small-scale target features in complex natural environments. To address this, we first created real datasets based on natural environments and improved dataset diversity using a combination of copy–paste enhancement and multiple image enhancement techniques. As for the choice of network, we chose YOLOV5s due to its nature of fewer parameters and easier deployment in the same class of models. Most improvement strategies to boost detection performance claim to improve the performance of privilege extraction and recognition. However, we prefer to consider the combination of realistic deployment feasibility and detection performance. Therefore, based on the hottest improvement methods of YOLOV5s, we try to make adaptive improvements in three aspects, namely attention mechanism, head network, and backbone network. The experimental results proved that the decoupled head and Slimneck based improvements achieved, respectively, 0.872 and 0.849, 0.538 and 0.479, 87.5% and 89.8% on the mAP0.5, mAP0.5:0.95, and Precision metrics, surpassing the results of the baseline model on these three metrics: 0.705, 0.405 and 83.6%. This result suggests that the adaptively improved model can better meet routine testing needs without significantly increasing the number of parameters. These models perform well on our custom dataset and are also effective on images that are difficult to detect by naked eye. Meanwhile, we find that YOLOV8s, which also has the decoupled head improvement, has the results of 0.743, 0.461, and 87.17% on these three metrics. It proves that under our dataset, it is possible to achieve more advanced results with lower number of model parameters just by adding decoupled head. And according to the results, we also discuss and analyze some improvements that are not adapted to our dataset, which also provides ideas for researchers in similar scenarios: in the booming development of object detection, choosing the suitable model and adapting to combine with other technologies would help to provide solutions to real-world problems.

Purpose: To evaluate the safety and efficacy of a new mesh in the pre-peritoneal repair of inguinal hernia., Methods: We randomly divided 120 patients undergoing pre-peritoneal repair into 2 groups between March 2012 and December 2013. The patients were randomized to receive the Swing mesh (n=60; study group) or the Modified Kugel mesh (n=60; control group). The primary end point of this study was to compare postoperative groin pain of the two groups. Complications, recurrence and analgesic use were also recorded., Results: There were no recurrent cases in either group throughout the study period. There was no significant difference between the groups with respect to postoperative complications. The VAS of early postoperative pain was 1.32±1.69 in study group and 1.52±1.93 in control group, with the difference being not statistically significant (p = 0.547). Concerning chronic pain, no remarkable statistically significant difference was observed between the two groups at 3-month, 6-month, 12- and 18-month follow-up period., Conclusion: Swing mesh can be safely and effectively used in inguinal hernia repair with the same advantage compared to the Modified Kugel mesh.
