肝门胆管癌的外科治疗60例临床分析

肝门胆管癌近年有增多趋势,本文报告我院1975年～1985年间肝门胆管癌60例,占全部肝外胆管癌82例之73.1％,占同期全部胆道手术3626例之1.65％。临床表现主要有三型:1)阻塞性黄疸29例,其中25例曾误诊为肝炎;2)急性胆管炎12例;3)长期胆道疾病14例,其他5例。本组行B超检查19例,ERCP10例,PTC39例。最后诊断根据PTC和/或ERCP,剖腹术及病理检查结果。 56例施行了手术治疗,仅6例施行肿瘤连同半肝切除,姑息性肝胆管内引流15例,外引流23例,其他方法12例。平均存活时间:6例切除组24.5月,48例姑息手术组8.7月,未手术的4例为5月。文中强调早期诊断,凡40岁以上出现阻塞性黄疸或“传染性肝炎”均须警惕胆管癌,进行B超,CT,ERCP或PTC检查,文中强调PTC是诊断本病重要手段,可选择进行右左肝管PTC。本病应争取手术切除,不能切除者行肝胆管内引流或外引流,二者疗效无明显差别。     

Diagnosis and management of abscesses in the basal ganglia and thalamus: A survey

Summary A review is made of the current management strategies of abscesses in basal ganglia and thalamus, based on a review of the literature and three of our own cases. Clinical picture, aetiology, diagnostic, surgical treatment and outcome are discussed. Stereotactic abscess puncture in combination with temporary drainage and rinsing of the abscess cavity in combination with systemic medication of antibiotics has become the management of choice with satisfactory results.     

Endoscopic sphincterotomy for common bile duct stones: Impact of recent technical advances

Technical improvements, such as mechanical lithotripsy, stenting or nasobiliary drainage, and wire-guided cannulation, have reduced the risk of complications in endoscopic sphincterotomy. To determine the extent of this reduction in risk, we assessed the medical records of 1352 patients with common bile duct stones in whom the procedure was conducted. Complications examined were: acute cholangitis and pancreatitis. Stone clearance was achieved in 1256 patients (92.8%), with an overall morbidity rate of 7.7% and a mortality rate of 0.15%. One hundred and forty-two patients had stones with a diameter greater than 20mm; 97 of these patients did not undergo lithotripsy. Cholangitis occurred in 10 of these 97 patients (10.3%), whereas, in the 45 patients who underwent lithotripsy, there were no cases of cholangitis (P=0.02). Stone removal was not immediately accomplished or attempted in 396 patients. In 82 of these patients in whom a stent or a nasobiliary drain was placed in the common bile duct, the incidence of cholangitis was 1.2%, significantly less (P=0.045) than the incidence of 6.4% in the other 314 patients given no stenting or nasobiliary drain. To overcome difficult cannulation, precut sphincterotomy was conducted in 134 patients and wireguided sphincterotomy, a recently introduced procedure, was conducted in 55 patients. When the precutting technique was used, the incidence of acute pancreatitis was significantly higher (8/134; 6.0%) than that in the patients in whom the standard procedure was conducted, i.e., neither the precut technique nor wire-guided ES was used (23/1218; 1.9%) (P=0.008). There were no cases of pancreatitis in the 55 patients in whom wire-guided sphincterotomy was performed, although the difference was not statistically significant because of the small number of patients (P=0.06). Based on these findings, we conclude that improved technologies have led to a significant reduction of complications in endoscopic sphincterotomy.

钻孔闭式引流和YL-1型穿刺针引流治疗慢性硬膜下血肿的疗效观察

目的比较钻孔闭式引流和YL—1型穿刺针引流在治疗慢性硬膜下血肿(CSDH)的疗效。方法回顾分析了我院收治的62例CSDH病人,45例行钻孔闭式引流术(甲组),17例行YL—1型穿刺针引流术(乙组),比较两组治疗效果。结果甲组复发率为6.5％,并发症率为4.1％,乙组复发率为27.7％,并发症率为22.2％。结论钻孔闭式引流较YL-1型穿刺针引流可明显减少CSDH复发率和并发症发生率。     

侧脑室引流术治疗脑室出血医院感染分析

目的 分析治疗脑室出血侧脑室引流术后感染发生率，探讨预防感染的方法及措施。方法 根据留管时间将患者分为甲、乙两组，按单侧引流及双侧引流分为A、B组，术后观察插管部位的感染发生情况，同时定期做血培养监测。结果 甲、乙组之间，经统计学处理P＜0．01，差异有高度显著性，A、B两组比较，P＞0．05，差异无显著性。结论 留管1～2周时间是安全的，超过2周，感染率上升，双侧引流术后感染率高于单侧引流者，此外，患者的全身状况及免疫力也与感染率明显相关。     

胆道外引流感染的预防

目的 总结胆道外引流感染的预防，以利提高胆道外引流的护理质量。方法 通过经治的临床病例总结各胆道外引流的观察和处理要点。结果 通过向患者说明胆道外引流的重要性，帮助患者适应和解决各种生活问题，消除心理负担，观察引流伤口、胆汁引流情况，保持引流管的位置并保持通畅，使良性患者早日康复，晚期恶性肿瘤患者的生活质量得以提高。结论 胆道外引流是胆道良性或恶性疾病引发梗阻治疗的一个措施，有时是唯一的姑息性手段，做好引流术后的观察及护理，对改善患者的全身情况，恢复身体健康，提高生活质量非常重要。

Effects of adrenergic and cholinergic antagonists on diameter of nasolacrimal drainage system

Background To determine the effect of an adrenergic and a cholinergic antagonist on the diameter of the lumen of the nasolacrimal drainage system. Methods The asymptomatic side of 38 patients (29 women, nine men) with unilateral stenosis/obstruction of the nasolacrimal drainage system was studied. The tear meniscus height (TMH) of the asymptomatic side was normal, and the lacrimal drainage system was patent as revealed by dacryocystography. The nasolacrimal drainage system of the asymptomatic side was infused with 100 μl of 0.01% bunazosin hydrochloride, a selective α-1 adrenergic antagonist, or 100 μl of 0.4% tropicamide, a muscarinic and cholinergic antagonist. Dacryocystography was performed to determine the diameter of the lumen of the nasolacrimal drainage system before and after the antagonists. Results Bunazosin reduced the diameter of the lumen significantly, and the changes were more marked in the nasolacrimal duct (NLD), especially the middle and the lower regions. The diameter of the lumen of the lacrimal sac was not changed significantly. In contrast, tropicamide did not cause any significant change in the diameter of the lumen of the nasolacrimal drainage system. Conclusions The alterations of the size of the lumen of the nasolacrimal drainage system, especially the NLD, by an adrenergic antagonist suggest that the lumen diameter is under continuous sympathetic tone, and the parasympathetic tone is weak. This study has not received any financial support.     

Two-dimensional echocardiography in the diagnosis of intracardiac masses: A prospective study with anatomic validation

The accuracy of two-dimensional echocardiography in the detection of intracardiac masses was verified in 334 patients who underwent cardiac catheterization in our laboratory over 21 consecutive months. A complete two-dimensional echocardiographic (2DE) examination was performed a day before catheterization. The presence or absence of a mass was verified at surgery in 77 patients who successively underwent mitral or aortic valve replacement (51), left ventricular aneurysmectomy with or without myocardial revascularization (25), and resection of atrial myxoma (2). In 32 patients 2DE revealed the presence of a mass-left or right atrial thrombi in 12, left atrial myxoma in 2, left ventricular thrombi in 16, and endocardial vegetations in 2. The other 45 patients were free of intracardiac masses on 2DE. Anatomic verification at surgery revealed the presence of an intracardiac mass in 34 patients. In 30 (true positives) of these, 2DE revealed the mass as well, and in 4 (false negatives) the presence of a mass had not been identified by 2DE. In 2 patients (false positives) the predicted mass was not found at surgery. Absence of a mass was correctly predicted by 2DE in 41 patients (true negatives). Thus 2DE detected intracardiac masses with sensitivity of 88.2% and a specificity of 95.3%. We recommend that 2DE be performed in all patients prior to hemodynamic study and/or cardiac surgery to enable safer management of patients with intracardiac masses during cardiac catheterization and/or cardiac surgery.
