目的 研究完全腹膜外腹腔鏡腹股溝疝修補術對睪丸血流灌注及體積的影響。 方法 2009年7月－2011年5月，對62例行完全腹膜外腹腔鏡單側腹股溝疝修補術男性患者進行自身前后對照研究，比較術前、術后患側睪丸的睪丸動脈（TA）、睪丸包膜動脈（CA）、睪丸內動脈（ITA）血流參數[收縮期峰值血流速度（PSV）、舒張未期血流速度（EDV）及血管阻力指數（RI）]、睪丸體積（TV）及血清睪酮的變化情況。 結果 患者獲隨訪7～24個月，平均15.6個月，無復發患者。術前及術后3、6個月時患側TV分別為（9.91 ± 3.72）、（10.23 ± 4.18）和（10.16 ± 3.94）cm3，同期血漿睪酮水平分別為（544.25 ± 123.72）、（532.89 ± 145.66）和（565.65 ± 138.13）μg/L，手術前后比較患側TV（F=1.350，P=0.263）、血漿睪酮水平（F=1.673，P=0.192）無統計學意義，血漿睪酮水平均在正常范圍內。術后3、6個月患側TA、CA和ITA的EDV明顯高于術前，RI較術前明顯降低，差異均有統計學意義（P＜0.05）；PSV與術前比較差異無統計學意義（P＞0.05）。術后3個月患側睪丸各動脈PSV、EDV、RI與術后6個月比較差異無統計學意義（P＞0.05）。 結論 完全腹膜外腹腔鏡腹股溝疝修補術后患側睪丸血流灌注情況可能會有所改善，不影響TV及血清睪酮水平。
Objective To explore the relationship between preoperative fasting plasma glucose (FPG) and postoperative pulmonary complications (PPCs) in type 2 diabetic patients undergoing elective thoracoscopic lung resection, and provide a reference for prediction and prevention of PPCs in the clinic. Methods A retrospective analysis was performed on the type 2 diabetic patients who underwent elective thoracoscopic lung resection for the first time in our hospital from January 2017 to March 2021. According to the level of FPG one day before the operation, the patients were divided into three groups: a hypoglycemia group (<6.1 mmol/L), a medium level blood glucose group (≥6.1 mmol/L and <8.0 mmol/L) and a high blood glucose group (≥8.0 mmol/L). Besides, the patients were divided into a PPCs group and a non-PPCs group according to whether PPCs occurred. The risk factors for PPCs were analyzed by logistic regression analysis, and the predictive value of preoperative FPG level on PPCs was estimated by the area under the receiver operating characteristic curve (AUC). Results A total of 130 patients were included, including 75 (57.7%) males and 55 (42.3%) females with an average age of 63.5±9.0 years. Logistic regression analysis showed that compared to non-PPCs patients, the level of preoperative FPG (P=0.023) and smoking history ratio (P=0.036) were higher and the operation time was longer (P=0.004) in the PPCs patients. High FPG level on preoperative day 1 and longer operation time were associated with PPCs risk. Besides, the preoperative FPG of 6.79 mmol/L was the threshold value to predict the occurrence of PPCs [AUC=0.653, 95%CI (0.559, 0.747), P=0.003]. Conclusion There is a certain correlation between preoperative FPG level and postoperative PPCs, which may be used as an index to predict the occurrence of PPCs.
