暴露前牙龈下残根进行桩冠修复

本文综述了暴露前牙龈下残根进行桩冠修复的两种方法,即牵引法与牙冠延长术,并对两者进行了比较、总结,在临床上有指导意义。     

合并异常冠状动脉法洛四联症和右心室双出口一期根治术

目的 总结合并异常冠状动脉的法洛四联症和右心室双出口一期根治术的经验，探讨有关外科技术的改进。方法1995年6月至2002年6月完成该类一期根治术12例，其中2例采取了肺动脉移位、3例在游离的左前降支下加宽右室流出道、5例改变右室切口并在冠状动脉下缝合、2例经肺动脉和右房疏通流出道。结果无手术死亡。随访3个月～6年，无晚期死亡和并发症发生。结论合并异常冠状动脉的法洛四联症和右心室双出口的一期根治手术是可行的，且效果良好，但必须采用适当的外科技术以保护异常的冠状动脉。     

老年急重症胆管炎临床分析

目的：探讨重症胆管(ACST)患者的临床特点及死亡原因。方法：分析我院近十五年来收治46例ACST的治疗情况。结果：手术41例．非手术5例，死亡9例，其中手术治疗死亡6例。结论：老年ACST患者，伴发病多，死亡率高，及时就诊，早期应用大量激素，选择适宜手术方法是降低死亡率的关键。     

The Post Therapy Breast

Both systemic and local therapy, for conditions of the breast and unrelated to it, may produce manuno-graphic changes. Some of these are characteristic, such as the pattern of scarring seen in reduction mammo-plasty. In many other instances, however, the changes produced overlap features commonly seen in malignancy. A knowledge of the timing, natural history and spectrum of these changes will aid mammographic interpretation.     

脑干区占位病变的手术入路

本文报告了1990年5月以来脑干区大型、复杂占位病变15例.其中,位于脑干内3例,脚间窝2例,岩尖部4例,全岩骨区1例,全斜坡区2例,第四脑室内3例.本组采用以扩大了的岩骨入路为主的联合入路,行肿瘤全切除8例,次全切除5例.2例仅作了活检加减压术.除1例死亡外,均恢复良好.本文结合文献,对脑干区手术入路进行了讨论.     

急性出血坏死性胰腺炎手术治疗的临床观察

总结了经手术证实为急性出血坏死性胰腺炎的５３例患者的手术疗效。发现该病应早期手术。若发病４天后手术，体温在３８℃以上、脉搏超过１２０次／分、收缩压在１２ｋＰａ（１ｋＰａ＝７．５ｍｍＨｇ）以下、有弥漫性腹膜炎、白细胞高于１６×１０９／Ｌ和术后有重要器官功能衰竭者，术后病死率明显增高。手术方法以胰腺坏死组织清除加三造瘘、腹腔三套管持续冲洗为优。抑制胰腺分泌的药物主要选用５氟脲嘧啶。引起胰腺感染的常见病原菌依次是大肠杆菌、肺炎克雷白杆菌、肠球菌、金黄色葡萄球菌、绿脓杆菌、奇异假单胞菌、链球菌、产气肠杆菌和脆弱类杆菌９种细菌。选用抗生素应遵守３个原则：①抗生素必须能通过血胰屏障。②能在胰腺组织中形成有效的治疗浓度。③能有效地抑制引起胰腺感染的病原菌。这样，才能取得良好的治疗效果。     

自发性食管穿孔的治疗改进

报道７例自发性食管穿孔治疗经验，并对诊断和治疗和治疗新方法进行了讨论，自发性食管穿孔早期诊断的重要依据是迅速获得完整，详细的发病史。可疑时通过食道造影，胸腔穿刺刺液的分析而确诊。一经确诊应急取早期食管修补，对发病时间长，全身情况差的病人，经积极准备后仍应急取食管修补，对不宜手术者给予食管冲洗促进穿孔愈合。同时给予有效的食管腔内外引流。     

KENNETH FITZPATRICK RUSSELL: THE FIRST READER TO THE GORDON CRAIG LIBRARY

A review of the life and achievements of Kenneth Fitzpatrick Russell, whose death in his 76th year robbed us of a civilized gentleman who was at the zenith of his creative output, would be a daunting task, if only because of the breadth of his hobbies and interests: art and medical literature; reading; sinology and seal carving; numismatics, medical philately; bookbinding, collecting bookplates; carpentry; metal work, including pewter casting and silversmithing; model ship building and cooking. Yet these various interests were simply a backdrop to his public career at the University of Melbourne and the Royal Australasian College of Surgeons, where he laid the foundations of an international reputation as scholar and collector.     

Gastric Bypass for Morbid Obesity: a Standard Surgical Technique by Consensus

Background: The gastric bypass operation has evolved since 1966 when it was first introduced. The purpose of this study was to determine the present state of gastric bypass by consensus among the members of the American Society for Bariatric Surgery (ASBS). Method: A questionnaire was sent to all members of the ASBS. Forty-three percent responded reporting over 41,200 cases. Results: Results were analyzed by using χ² tests with a null hypothesis. Surgeons agreed on several technical aspects, preferring a vertical to a horizontal stapleline; estimating, rather than measuring, the pouch volume at an average of 22 cc. Few surgeons divide the short gastric vessels, and only 25% of surgeons polled use a restrictive ring or band proximal to the gastroenterostomy. Most surgeons calibrate the gastroenterostomy, reporting a preferred average diameter of 12.3 cm. There was no consensus regarding forming the gastroenterostomy, 58% preferring hand-sewn and 42% stapled anastomoses. There was no consensus regarding dividing the gastric pouch from the bypassed stomach: Conclusion: The preferred gastric bypass is vertical, with the pouch estimated at 20-25 cc, and the gastroenterostomy calibrated at 12 mm diameter. The short gastric vessels need not be divided, and restrictive bands or rings are not preferred. This technique of gastric bypass should be used as the control procedure when modifications are tested in future trials. Randomized prospective studies are suggested to probe the benefits of division of the stomach pouch from the bypassed stomach.
