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)
There was no enough evidence to support the view that endovascular treatment could alternate the endarterectomy to be a standard treatment of carotid stenosis. A recent Cochrane systematic review found no difference in major outcomes between endovascular treatment and surgery. The randomised trials provided data to show that the main advantage of endovascular treatment for carotid artery stenosis was the avoidance of minor complications such as cranial nerve palsy and wound haematoma of surgery. Longer term follow also showed no difference in the rate of stroke during follow-up, but the confidence intervals were very wide allowing the possibility of a substantial difference in risk and benefits of the two treatments. There was no difference in avoidance of stroke between carotid stenting using protection devices and surgery, and the protection devices could cause additional complications.
目的 探討前路小切口頂椎切除聯合后路矯形手術治療重度僵硬性脊柱側凸的可行性及療效。 方法 2009 年7月－2010年9月，采用前路小切口頂椎切除聯合后路矯形手術治療重度僵硬性脊柱側凸18例。其中男9例，女9例，年齡10～24歲，平均14.5歲。其中15 例特發性脊柱側凸（Lenke 2型6例，Lenke 3型1例，Lenke 4型8例），2 例脊髓空洞合并脊柱側凸，1 例Chiari畸形合并脊柱側凸。術前剃刀背高度（6.8 ± 2.3）cm，主胸彎Cobb角（99.6 ±10.0）°，主胸彎頂椎偏距（7.3 ± 1.3）cm。 結果 前路手術切口10～13 cm，平均（11.4 ± 1.0）cm；前路手術時間170～300 min，平均（215.3 ± 36.8）min；失血量300～1 300 mL，平均（662.5 ± 274.8） mL。所有患者隨訪25～39個月，平均30.7個月。末次隨訪時，剃刀背高度（1.0 ± 0.6）cm，矯正率86.7%；主胸彎Cobb角（31.4 ± 11.4）°，矯正率68.7%；主胸彎頂椎偏距（2.2 ± 0.9） cm，矯正率69.6%。上胸彎、胸腰彎/腰彎的Cobb 角及頂椎偏距亦明顯矯正，冠狀面及矢狀面平衡與術前相比，差異無統計學意義（P＞0.05）。未發生神經系統并發癥，1例患者在前路手術后入ICU行呼吸支持治療12 h，1例患者出現椎弓根螺釘穿透椎弓根上壁，2例患者出現鈦網位置不佳，隨訪未見鈦網位置改變。 結論 采用前路小切口頂椎切除聯合后路矯形治療重度僵硬性脊柱側凸安全可行，矯形效果滿意。
Objective To explore the diameter change of the extrahepatic bile duct before and after laparoscopic cholecystectomy (LC). Methods From Jan. 2006 to Dec. 2007， 113 patients including chronic gallstone cholecystitis （n=55）, inactive cholecystolithiasis （n=46） and gallbladder polyps （n=12） were collected and treated by LC. The diameters of their extrahepatic bile ducts were measured by B ultrasonography before operation， 3 months and 6 months after operation. These data were collected and analyzed retrospectively. Results The diameters of the extrahepatic bile ducts of all patients before LC， 3 months and 6 months after LC were (5±2) mm, (8±2) mm and (6±2) mm respectively. And in chronic gallstone cholecystitis patients they were (5±2) mm, (9±2) mm and (6±2) mm respectively， in inactive gallstone cholelithiasis patients they were (5±2) mm, (8±2) mm and (6±2) mm respectively， and in gallbladder polyps ones they were (5±2) mm, (7±2) mm and (5±2) mm respectively. Conclusion The change of the extrahepatic bile duct diameter after LC is a dynamic process. It is enlarged on the third month after operation than before operation. In the sixth month after operation marked retraction occurs, and compared with before operation, it shows no obvious statistic significance.
