Objective To summarize the visual outcome of patients with severe ocular trauma treated with vitreous surgery. Methods Clinical data of 188(191 eyes) with severe ocular trauma treated with vitreous surgery in a period from November 1996 to April 1998 were analysed retrospectively. Results The study included penetrating injury in 56 eyes, foreign bodies in the posterior segment in 70 eyes, blunt injury in 41 eyes , and globe rupture in 24 eyes. Main complications included endophthalmitis in 35 eyes, choroidal bleeding in 20 eyes, retinal detachment in 60 eyes, and vitreous hemorrhage in 97 eyes. Post-opera-tively, out of 188 eyes, except for 3 of patients too young to examine, visual acuity improved in 133(70.7%), including 85(45.2%) with visal acuity 0.02-1.0, 46(24.5%) remained unchanged; and 9(4.8%) had worse vision. Among 34 with no-light-perception, 12 had light-perception or over. Conclusion A majority of severe trauma eyes can be salvaged with considerable visual recovery after adequate and timely vitreous surgery. (Chin J Ocul Fundus Dis,1999,15:4-6)
Objective To summarize the experience of open heart operation on neonates with critical and complex congenital heart diseases and evaluate the methods of perioperative management. Methods From May 2001 to January 2003, 12 patients of neonates with congenital heart diseases underwent emergency operation. Their operating ages ranged from 6 to 30 days, the body weights were 2.8 to 4.5 kg. Their diagnoses included D-transposition of the great arteries in 4 cases, ventricular septal defect with atrial septal defect in 5 cases, complete atrioventricular septal defect, obstructed supracardiac total anomalous pulmonary venous drainage and cardiac rhabdomyomas in 1 case respectively. 12 cases were operated under moderate or deep hypothermic cardiopulmonary bypass. Results All cases were observed in ICU for 2-11 days and discharged 7-19 days after operation. The postoperative complications included low cardiac output, mediastinal infection, respiratory distress syndrome, systemic capillary leak syndrome and acute renal failure. All cases were cured and the follow-up (from 6 months to 2 years) showed satisfactory outcome. Conclusion A particular cardiopulmonary bypass and proper perioperative management is very important to ensure the successful outcome. Peritoneal dialysis is an effective and safe method for treating acute renal failure after cardiac operation in neonates.
ObjectiveTo summarize experience of surgical treatment of ascending aortic aneurysm and analyse related problems.MethodsOne hundred and fourteen (containing 62 cases had aortic dissection) consecutive cases underwent replacement of diseased ascending aorta alone (9 cases) or Bentall operation.ResultsThere were seven operative death (6.14%). The cardiac function, in six of them, was in class Ⅳ(NYHA) preoperatively. Follow up was completed in 107 patients, with a duration of 40±30 months. Eight patients succumbed due to intracranial hemorrhage (3 cases), rupture of abdominal aortic lesion (3 cases), cardiac failure after coronary artery bypass grafting (1 case), and sudden death of unknown cause (1 case),respectively. All 99 long term survivors (86.8%) were in NYHA class Ⅰor Ⅱ.ConclusionThe results indicate that Bentall operation for treating ascending aortic aneurysms and aortic insufficiency, or aortic replacement alone for treating ascending aortic aneurysm gives good functional recovery and an active life for the vast majority of survivors.
ObjectiveTo investigate the technique and efficacy of left atrial appendage (LAA) occlusion during off-pump coronary artery bypass grafting (OPCABG) in elderly patients with coronary artery disease (CAD) and atrial fibrillation (AF).MethodsFrom 2013 to 2018, 84 elderly patients with CAD and AF with reduced left ventricular ejection fraction (LVEF< 50%) underwent OPCABG in our department. There were 54 males and 30 females at age of 70-82 years. They were divided into a left atrial appendage (LAA) occlusion group (n=56) and a non-LAA occlusion group (n=28). Postoperative antithrombotic therapy: the LAA occlusion group was given warfarin + aspirin + clopidogrel “triple antithrombotic therapy” for 3 months after operation, then was changed to aspirin + clopidogrel “dual antiplatelet” for long-term antithrombotic; the non-LAA occlusion group was given warfarin + aspirin + clopidogrel “triple antithrombotic” for long-term antithrombotic after operation. The clinical effectiveness of the two groups was compared.ResultsAll patients underwent the surgery successfully. There were 56 patients in the LAA occlusion group, including 44 patients of LAA exclusion and 12 patients of LAA clip. The time of LAA occlusion was 3 to 8 minutes. There was no injury of graft vessels and anastomotic stoma. Early postoperative death occurred in 2 patients (2.4%). There was no statistical difference between the two groups in postoperative hospital stay (P=0.115). Postoperative LVEF of the two groups significantly improved compared with that before operation (P<0.05). There was no stroke or bleeding in important organs during hospitalization. During follow-up of 1 year, no cerebral infarction occurred in both groups, but the incidence of bleeding related complications in the LAA occlusion group was significantly lower than that in the non-LAA occlusion group (3.6% vs. 18.5%, P=0.036).ConclusionFor elderly patients with CAD and AF with reduced LVEF, LAA occlusion during OPCABG can effectively reduce the risk of stroke and bleeding related complications, and without increasing the risk of surgery.
目的:探讨不同手术入路在贲门癌治疗中的临床应用。方法:回顾性分析我院2003年8月至2009年1月期间收治的153例贲门癌患者的临床资料,根据不同手术入路分为经腹组(n=74)、胸腹联合组(n=27)和经胸组(n=52),对3组患者的手术中、术后恢复情况以及随访结果进行对比分析。结果:手术切除率100%,围手术期无死亡病例。经腹组手术时间短于经胸组和胸腹联合组,术中出血量也少于经胸组和胸腹联合组,但差异无统计学意义(Pgt;0.05)。胸腹联合组和经腹组清扫的淋巴结数目明显多于经胸组,差异有统计学意义(Plt;0.05)。经腹组患者术后住院时间和术后并发症发生率明显少于胸腹联合组和经胸组,差异有统计学意义(Plt;0.05)。3组患者的术后局部复发率和远处转移率的差异均无统计学意义(Pgt;0.05),3年和5年生存率的差异也无统计学意义(Pgt;0.05)。结论:经腹贲门癌切除术是安全和有效的,配合吻合器的使用,操作也是可行的。
目的 了解单纯胆囊切除术患者围手术期抗菌药物的使用情况及合理性，促进临床合理用药。 方法 对昆明医学院第二附属医院2004年7～9月期间出院的661例单纯胆囊切除术患者应用抗菌药物的合理性进行回顾性分析。结果 胆囊切除患者抗菌药物应用共涉及9大类39个品种，使用率为100%。预防用药380例（57.49%），其中单用38例(10.00%)，平均用药6.55 d，平均住院时间10.79 d； 两联281例(73.95%)，平均用药6.49 d，平均住院时间12.30 d； 三联57例(15.00%)，平均用药6.52 d，平均住院时间11.75 d； 四联4例(1.05%)，平均用药6.75 d，平均住院时间9.00 d。感染治疗281例(42.51%)，其中单用10例(3.56%)，平均用药9.60 d，平均住院时间15.10 d； 两联206例(73.31%)，平均用药11.25 d，平均住院时间15.79 d； 三联56例(19.93%)，平均用药15.23 d，平均住院时间15.23 d； 四联9例(3.20%)，平均用药13.00 d，平均住院时间21.78 d。结论 单纯胆囊切除术患者抗菌药物使用存在一些不合理现象，应按围手术期给药方案进行。加强抗菌药物使用的管理和监督，不仅减少耐药菌株及不良反应的产生，而且对降低医药费用具有积极的意义。
Objective To investigate the changes of renal medulla aquaporin 2 expression and morphological changes of epithelia of collecting tube after bile duct recanalizaiton operation. Methods Thirty rats were divided into two groups randomly. Common bile duct ligation was performed on 20 experimental rats with silicon tubes 2 mm in extre-diameter, and sham operation on the other 10 rats. Seven days later, bile duct recanalizaiton was performed on obstructive jaundice group and sham operation on contrast group. Experimental rats were divided into two subgroups randomly. Half of them were killed immediately and the others would be killed 24 hours later. Serum of each rat was collected to detect hepatic function and renal function. Renal medulla was fixed for microscopic examination and was kept in the -80 ℃ refrigerator for aquaporin 2 expression measurement by Western blot technique. Results All of the animals accomplished the experiment smoothly. Golden ascites were found in the rats of obstructive jaundice group. Twenty-four hours after recanalization, serum bilirubin levels decreased 〔(45.95±8.39) μmol/L〕, P＜0.01, and there was no significant change in blood urine and creatine level. Compared with sham operation group (21 966.20±1 544.70), expression of aquaporin 2 decreased significantly after common bile duct ligation in obstructive jaundice group (15 665.30±1 181.85), P＜0.01. After recanalizaion, the expression of aquaporin 2 in obstructive jaundice group increased (19 490.80±4 239.32), P＜0.01. Conclusion Common bile duct obstruction would lead to epithelium injury of renal collecting tube, and down regulate the aquaporin 2 expression.
