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 explore the effectiveness and safety of exchange of cerebrospinal fluid in the treatment of subarachnoid hemorrhage (SAH). Methods Sixty SAH patients diagnosed by CT and lumbarpuncture were randomly assigned into a control group (n =30, received conventional treatment) and a treatment group (n =30, received exchange of cerebrospinal fluid plus conventional treatment). The main complications and effectiveness between the two groups were compared. SPSS 10.0 was used for statistical analysis. Results Compared with the control group, complications of persistent headache ( P =0.002 and 0. 007 respectively), cerebral vasospasm ( P =0. 028 ) and hydrocephalus ( P =0. 038 ) were fewer in the treatment group. No significant difference in the incidence of rehaemorrhagia was found between the two groups (P = 1. 000). Better effectiveness was observed in the treatment group (RR. 3.00, 95% CI 1. 014 to 8. 880, P = 0. 044 ). Conclusions Exchange of cerebrospinal fluid plus conventional treatment is more effective than conventional treatment alone in the treatment of SAH.
Objective To summarize the available clinical evidence on the treatment of non-proliferative diabetic retinopathy (NPDR). Methods Based on the basic methods and principles of evidence-based medicine, we searched and evaluated the NPDR-related evidence from the Cochrane Library(Issue 3,2007), PubMed (1966 to June 2007) and CBM(1979 to June 2007) Results We finally identified 1 systematic review and 20 randomized controlled trials. Clinical evidence showed that critical glycemic control and blood pressure control were essential in the treatment of NPDR, which might delay the progression of retinopathy. The effectiveness of other therapeutic measures needed to be further investigated. Conclusion NPDR is the early stage of diabetic retinopathy (DR). Relevant systematic reviews and high-quality randomized controlled trials have confirmed the effectiveness of critical control of blood glucose and blood pressure for NPDR. The effectiveness of other therapeutic measures needs to be confirmed by systematic reviews of high quality and rigorously designed randomized, multi-center and large-scale trials.
目的:观察波及黄斑区的孔源性视网膜离术后各时期黄斑区相干光断层扫描图像特征及孔源性视网膜脱离患者眼轴长度与手术后视网膜下液吸收的关系,分析其与视力恢复过程的相关性。方法:对 53例(53眼)波及黄斑区的孔源性视网膜脱离经巩膜外加压术后视网膜复位的患者分别于术后1周、1月、3月、6月进行相干光断层扫描检查,观察黄斑区形态变化及黄斑区视网膜下液残留情况,并将检查结果与患者病程、眼轴长度以及手术后视力恢复情况等临床资料进行了对比分析。 结果:术后1周,所有病例均残留程度不等的视网膜下液,随着时间的延长,积液不断吸收。与之相对应,患者视力逐渐提高。术后3月,黄斑区视网膜下积液全部吸收累计33例, 其中眼轴长度大于26 mm患者视网膜下液吸收速度较慢,差异有统计学意义(P<0.05)。术后6月,43例患者黄斑区视网膜下积液全部吸收,仍有 7例神经上皮浅脱离,3例局限性神经上皮脱离。术后6月时患者最佳矫正视力lt;0.05者7眼,005~03者17眼,≥0.3者29眼。结论:光学相断层扫描能从微观角度清晰地显示视网膜复位后黄斑区形态结构的变化。巩膜外加压术后视网膜复位的患者黄斑区仍残留少量的视网膜下积液,视网膜下积液的逐步吸收能较好地解释术后视力的恢复过程。眼轴长度大于26mm患者视网膜下液吸收速度较慢。
目的 探讨捆绑式胰肠吻合术的改良方法。方法 对8例胰十二指肠切除术患者行捆绑式胰肠吻合术时采用带血管蒂的大网膜包绕空肠浆肌鞘,以达捆绑之目的。8例中行桥袢空肠造瘘5例,胆总管造口T管引流3例,并观察其术后5 d内每天平均引流液量。结果 8例患者均治愈出院,无胰瘘、胆瘘发生; 5 d内每天平均引流液量除第1天胆总管造口低于空肠造瘘外,其余4 d每天平均引流液量均明显高于空肠造瘘; 1例空肠造瘘者术后第8天继发胰腺残端出血,经电灼后止血。结论 带血管蒂的大网膜包绕空肠浆肌鞘完全可以代替粗线环绕空肠结扎,并使整个空肠浆肌鞘与胰腺紧贴,更利于胰肠间愈合; 空肠造瘘或胆总管造口对桥袢空肠均有减压引流的作用,但T管引流更简单、有效、省时。
目的 探讨Miles手术重建盆底腹膜困难时的处理对策。方法 对Miles手术重建盆底腹膜困难的患者,根据其大网膜的解剖情况,将带血管蒂大网膜经左或右结肠旁沟放入骶前腔,利用大网膜去填塞骶前腔或修补盆底腹膜缺损。结果 3例患者分别用带蒂大网膜加气囊填塞骶前腔、带蒂大网膜单纯填塞骶前腔、带蒂大网膜修补盆底腹膜等方法,减轻了缝合盆底腹膜时的张力,使盆底腹膜得以顺利重建。结论 用带血管蒂大网膜填塞骶前腔或修补盆底腹膜缺损,可防止Miles术后并发症发生,促进患者早日康复。
Objective To investigate the clinical application of the right grstroepiploic artery (RGEA) in offpump coronary artery bypass grafting (OPCAB). Methods We retrospectively analyzed the clinical data of the 38 patients who underwent RGEA grafts for OPCAB between December 2008 and July 2009 in the First Affiliated Hospital of Nanjing Medical University. According to the difference of grafts, 76 patients undergoing OPCAB were divided into two groups. In the RGEA group, there were 38 patients including 36 males and 2 females with an age of 65.87±6.29 years. For the patients in this group, OPCAB was carried out with RGEA and other routine conduits as grafts. The control group had 38 patients including 35 males and 3 females with an age of 66.68±6.24 years. They underwent OPCAB with left internal mammary artery (LIMA), radial artery (RA), or saphenous vein (SV) as grafts. The intraoperative and postoperative clinical data for patients in both groups were analyzed and compared. Results All operations were carried out without serious complications like reoperation for bleeding, functional delayed gastric emptying, or severe infection, and no operative death occurred. Compared with the control group, operative time in the RGEA group was longer (295.53±45.16 min vs. 262.50±42.44 min,P=0.001), the number of anastomotic stomas [CM(159mm]was less (4.71±0.56 vs. 5.29±0.92, P=0.002), and less intraoperative plasma was consumed (194.74±186.30 ml vs. 565.79±382.70 ml, P=0.000). The 24 h drainage loss (394.71±205.36 ml vs. 536.32±258.85 ml, P=0.008), the blood cell consumption (1.67±1.48 U vs. 2.81±2.48 U, P=0.010) and the postoperative hospital stay (12.47±3.20 d vs. 15.47±9.31 d, P=0.035) were significantly lower in the RGEA group compared with those in the control group. Meanwhile, the time of postoperative mechanical ventilation time was longer in the RGEA group than that in the control group (1 398.82±1 349.94 min vs. 985.39±170.30 min, P=0.036). Seventytwo patients were followed up for a period from 9 to 17 months with 4 cases lost. No myocardial ischemia occurred in both groups of patients. Conclusion RGEA is an effective arterial conduit for OPCAB. It needs high technology and takes long operative time to apply RGEA in OPCAB.
