目的 分析急性阑尾炎及易与之混淆的其他急腹症的CT图像特征，探讨CT检查对急性阑尾炎诊断及鉴别诊断思路的辅助意义。方法 收集2009年6月至2012年6月期间南方医科大学附属小榄医院收治的120例初步诊断为急性阑尾炎患者的CT影像资料，回顾性分析和对比CT征象，研究其与最终诊断之间的内在联系。结果 120例患者中，单纯性阑尾炎15例，化脓性阑尾炎45例，阑尾坏疽、穿孔25例，阑尾脓肿10例；其他急腹症20例；5例未确诊。阑尾炎患者的术前CT征象因阑尾炎种类不同而略有区别，有56例发现粪石；而其他急腹症的CT征象有结肠管壁局限性增厚、肾输尿管高密度影、肾周筋膜增厚、子宫附件区囊性或实性肿物、肠系膜淋巴结肿大、腹水等。结论 CT检查对急性阑尾炎诊断与鉴别诊断思路的形成具有重要的价值。
Objective To explore the value for localization of cystic lymph node in laparoscopic cholecystectomy. Methods Clinical data of 100 cases who underwent laparoscopic cholecystectomy in Affiliated Hospital of Southern Medical University and The Third Division Hospital of Xinjiang Production and Construction Corps were collected to analyze retrospectively, for exploring the relationship of localization of cystic lymph node, cystic artery, cystic duct, and liver door. Results Of the 100 cases, 81 cases (81.0%) were found lymph node, in which 76 cases (76.0%) were found 1 lymph node and 5 cases(5.0%) were found lymph node more than 1, the other 19 cases(19.0%) were not found lymph node. Of the 76 cases who were found only 1 lymph node, lymph nodes were located above the anterior branch of cystic artery in 48 cases, below the anterior branch of cystic artery in 21 cases, and adjacent to the posterior branch of cystic artery in 7 cases. The operation was successful in all patients without death, of which 3 cases were transferred to laparotomy. The operation time were (43.0±6.5) min (25-116 min), and hospital stay after operation were (3.0±0.6) days (2-6 days). No serious complications of bile leakage, bile duct injury, and death happened after operation, and all cases were cured and discharged. Conclusion Cystic lymph node in the calot triangle is in relatively fixed position of laparoscopic cholecystectomy, it can help to guide judging anatomical hepatic portal region of each organization structure, and can to confirm the location of cystic artery and cystic duct, which is helpful to prevent injury during the operation of laparoscopic cholecystectomy.
