目的探讨提高腹股沟疝的治疗效果。方法回顾性总结我院1990~2001年采用低张力疝修补术治疗126例腹股沟疝的经验。 结果126例患者手术过程顺利，手术时间平均45 min, 平均住院8 d，无伤口感染。术后并发尿潴留5例，阴囊积液4例，经对症治疗后痊愈出院。本组病例术后随访2年无一复发，87例随访2~7年，仅1例复发。结论该术式符合解剖生理特征，掌握其手术适应证，可以避免术后复发。
Lung cancer is the malignant tumor with the highest incidence and mortality rate in China, which seriously threatens the life and health of Chinese people. Locally advanced unresectable non-small cell lung cancer is characterized by high heterogeneity and poor prognosis, and durvalumab consolidation therapy after concurrent chemoradiotherapy is the main treatment modality. In recent years, advances in targeted therapies and immunotherapy have changed the treatment landscape of lung cancer. A portion of locally advanced or advanced non-small cell lung cancer that was initially unresectable is down-staged and converts to surgically operable radical resection after comprehensive treatment, and this surgical treatment strategy is called conversion surgery. With the progress of comprehensive treatment modalities, it may occupy an increasing proportion in thoracic surgery in the future. This article reviews the treatment modality and conversion surgery for locally advanced unresectable non-small cell lung cancer.
Objective To investigate the influence of CO2-insufflation pressure on invasion potential of the colon cancer cells. Methods With an in vitro artificial pneumoperitoneum model, SW1116 human colon cancer cells were exposed to CO2-insufflation of 5 different pressure groups: 6, 9, 12, 15 mm Hg and control group, respectively for 1 h. The invasion capacities of SW1116 cells exposed to CO2-insufflation of 5 different pressure groups were detected by cell adhesion/invasion assay in vitro. Results Immediately following exposure to 15 mm Hg CO2 insufflation, the invasion of SW1116 cells decreased significantly compared to the cells before exposure. At the 0 h time point, the cells exposed to 15 mm Hg were significantly less invasive than those exposed to the other insufflation pressure (P＜0.05), and the cells exposed to 6 mm Hg were more invasive than cells exposed to the other insufflation pressure (P＜0.05). And 72 h after exposed to CO2-insufflation, the differences between the pressure groups were not significant. Conclusion CO2-insufflation induced a temporary change in the invasion capacity of cancer cells in vitro, higher pressure of CO2-insufflation inhibits the invasion potential.
