Treatment of iatrogenic biliary obstruction by balloon dilatation of a biliary jejunal fistula

Biliary obstruction and multiple hepatic abscesses occurred in a patient after ligation of a segmental branch of the right hepatic duct. The patient was successfully managed by transhepatic biliary drainage and balloon dilatation of an internal fistula that developed between the ligated duct and a Roux limb of jejunum. Internal biliary fistulas may be dilated using interventioanl radiologic techniques to permit nonobstructed bile flow. Implications for the nonsurgical treatment' of biliary strictures are discussed.     

Bilateral choanal atresia and paranasal sinus hypoplasia in an adult patient with hypogammaglobulinaemia

We present an unusual case of a young female patient presenting with bilateral choanal atresia, which was probably acquired, associated with nasal and paranasal sinus hypoplasia and hypogammaglobulinaemia.     

Acoustic rhinometry in nasal provocation test in perennial allergic rhinitis

Acoustic rhinometry is one method to evaluate nasal geometry by an acoustic reflection technique. The aim of this study was to investigate the changes in acoustic rhinometry after nasal provocation in patients with exclusively perennial allergic rhinitis. In 19 patients, acoustic rhinometry and active anterior rhinomanometry were performed before and after nasal provocation test. There was a statistically significant nasal flow reduction measured by active anterior rhinomanometry after nasal provocation (p < 0.05) and a median symptom score of four points, both indicating a positive response to nasal provocation. On the other hand, there was no statistically significant change in the values of acoustic rhinometry after nasal provocation (p > 0.05). In patients with exclusively perennial allergic rhinitis, acoustic rhinometry does not seem to significantly change after nasal provocation. In contrast, active anterior rhinomanometry values decreased significantly after nasal provocation. The presented results indicate that acoustic rhinometry does not seem to be a diagnostic method superior to active anterior rhinomanometry in this context.     

心包膜移植在结膜囊成形术中的应用

目的：探讨保存人心包膜移植治疗结膜囊狭窄的临床效果及安全性。方法：对眼球摘除术后伴有结膜囊狭窄综合征的26例26眼，利用心包膜移植行部分结膜囊成形术，术后随访观察3～12个月，平均8个月。结果：24眼（92．31％）在术后30～60天移植的心包膜被结膜覆盖，感染1例（3．85％），结膜囊狭窄1例（3．85％）。结论：保存心包膜移植治疗结膜囊狭窄取材方便，疗效显著，操作简单。     

Giant intracranial aneurysm of the anterior communicating artery treated by direct surgery using A3–A3 side-to-side anastomosis and A3-RA graft-STA anastomosis

Summary We describe a giant aneurysm of the anterior communicating artery (ACoA) which was treated with a STA-RA graft-A3 bonnet bypass and A3–A3 side-to-side anastomosis. A giant and partially thrombosed ACoA aneurysm was partially coated 3 years before his current presentation, its gradual increase producing visual field disturbances. An A3–A3 side-to-side anastomosis and STA-RA graft-A3 bonnet bypass were performed. The aneurysm was dissected, and the thrombus removed under transient parent-artery occlusion. The aneurysmal neck was successfully clipped without encountering ischemic changes. This strategy may be useful for treating giant or thrombosed aneurysms in the region of the ACoA.     

急诊左半结肠一期切除吻合术25例治疗体会

目的探讨急诊左半结肠切除一期肠吻合的可行性。方法腹腔探查完后，用布带结扎横结肠，游离肠系膜后，于预切除肠段的上端切开作肠外减压，挤压排空粪便，切除病变肠管，端端吻合，术后作肛管扩张，停留肛管引流，胃肠减压。结果全部病人预期痊愈出院，无发生吻合口漏和腹腔污染。结论该法有利于吻合口的愈合，增加左半结肠一期切除吻合的安全性，减少第2次手术痛苦，可推荐为左半结肠急诊切除一期吻合的良好方法。     

埋没导引缝合法矫治鹰钩鼻鼻尖畸形

目的介绍一种较新的矫治鹰钩鼻鼻尖畸形的手术方法。方法自1995年2月至2005年5月,采用埋没导引缝合技术对18例鹰钩鼻鼻尖畸形患者进行手术矫治,术后结合鼻管支撑的鼻孔悬吊法外固定7~10d。结果术后经14个月至3年的随访,18例患者的鼻尖外形良好,形态满意。其中1例患者因鼻腔内悬吊线穿透引起轻度炎症,术后3周剪除缝线,5d自愈。结论采用埋没导引缝合的手术方法对鹰钩鼻鼻尖畸形患者进行矫治,并结合缝合、悬吊和固定,获得了良好的术后效果。此方法是一种较理想的手术方法,值得推广应用。     

白内障手术结膜囊及房水细菌培养的临床观察

目的　探讨白内障术中结膜囊、房水污染与眼内炎的关系。方法　对 74例 80眼白内障囊外摘除术中结膜囊及房水进行细菌培养。结果　 16 0份细菌培养标本中 ,细菌培养阳性者 18株 ,平均培养阳性率为 11.3%。房水为 8株 ,检出率为 10 .0 % ;结膜囊为 10株 ,检出率为 12 .5 %。以表皮葡萄球菌为主 (11 18) ,其中 3眼结膜囊及房水检出同一菌株。检出阳性的 15眼无 1例发展成眼内炎。结论　白内障摘除术后前房有少量细菌 ,虽不致发生眼内炎 ,但不可掉以轻心。     

Effects of STA-MCA anastomosis for ischaemic oculopathy due to occlusion of the internal carotid artery

Summary Effects of STA-MCA anastomosis on two patients with neovascular glaucoma due to occlusion of the internal carotid artery are presented. Both patients improved in visual acuity and central retinal artery pressure as well as in signs of transient ischaemic attack. Postoperative angiography showed a marked decrease in collateral flow through the ophthalmic artery, which is reversed from the normal direction, with the development of blood flow through the anastomosis. Discussion is offered indicating that the lack of collateral flow through both the anterior and posterior communicating arteries is important in addition to occlusion of the internal carotid artery in order to produce full-blown ischaemic oculopathy such as venous stasis retinopathy, neovascular glaucoma or rubeosis iridis. It is stressed that EC-IC bypass surgery should be performed soon after the appearance of ischaemia and before the development of neovascular glaucoma or rubeosis iridis in order to obtain normal vision. In ischaemic oculopathy the results of EC-IC bypass can be evaluated objectively and quantitatively by many noninvasive neuro-ophthalmological tests which are important in discussing the efficacy of the bypass surgery.
