Treatment of gingival lichen with free palatal grafts

BACKGROUND: Recalcitrant gingival erythematous lichen planus/lichenoid lesions comprise a considerable therapeutic problem. The objective of this study was to evaluate the therapeutic effect of grafting keratinized oral palatal mucosa to the sites of gingival lichen. METHODS: In 12 patients 20 grafts were transplanted to buccal gingival lesions. Mean age of the patients was 59.8 +/- 7.1 years (range 46-71 years). The mean observation time was 32 +/- 32.7 months (range 5-97 months). RESULTS: On a 4-point clinical grade scale (0-3), 12 (60%) transplants showed complete healing grade 3, six (30%) grade 2 and two (10%) grade 1. CONCLUSIONS: Using oral mucosal grafts from the palatal mucosa for the treatment of recalcitrant erythematous gingival lichen planus/lichenoid lesions seems to be a promising treatment modality.     

Use of an aortic connector system for vein grafting

OBJECTIVE: The aortic connector system was used to minimize cerebrovascular complications when performing the proximal anastomosis of vein grafts during coronary artery bypass grafting (CABG). The goal of this study was to investigate the intermediate outcomes of patients undergoing CABG with the aortic connector system. METHODS: The aortic connector was used on nine patients undergoing CABG between November 2002 and July 2003. Intermediate outcomes of the patients were examined, and the results of coronary angiography, which were performed before patient discharge and at least 6 months after discharge, were evaluated. RESULTS: There were no operative deaths or cerebrovascular accidents. One patient died 9 months after discharge, one patient had angina, and the remaining seven patients were asymptomatic. When evaluating the results of angiography performed before patient discharge, two of the 21 distal vein graft anastomoses were occluded (patency rate, 90.5%), but there was no stenosis or occlusion at the proximal anastomoses sites that were performed using the aortic connector. When evaluating the results of the second angiography performed after patient discharge, four of the eight proximal anastomoses were patent, one was completely occluded, two had 90% stenosis and one had 75% stenosis. Further, four of the 18 distal anastomoses were occluded (patency rate, 77.8%). There was no significant difference in graft flow or device size when comparing patients with patent vein grafts and those with stenotic or occluded vein grafts. CONCLUSION: Intermediate outcomes of vein grafting using the aortic connector were suboptimal. Long-term outcome data are forthcoming.     

开放性骨质疏松性股骨远端骨折的治疗和伤害控制论的应用

目的 总结治疗开放性骨质疏松性股骨远端骨折的治疗和应用伤害控制观念的体会。方法 回顾性分析2002年1月～2003年12月60岁以上股骨远端开放性骨折住院治疗的病例21例。应用伤害控制学的原则：全面评价其外伤程度，条件允许则急诊手术，危重患者就临时固定，监护患者的生理指标，限期施行骨折固定手术。结果 17例患者获得超过4个月以上的随访，平均随访7．3个月。17例患者在术后平均15周内(79～168d)达到临床愈合。参照Shelbourne疗效评定标准，膝关节功能优良率达到78％。结论 治疗开放性股骨远端骨质疏松性骨折需要应用伤害控制的观念，兼顾患者全面情况，同时治疗骨质疏松和其它并存疾病。手术固定以股骨髁上逆行交锁髓内钉为主，早期功能锻炼。     

Flexor digitorum profundus tendongrafting (extrasynovial donor tendons)

Although the prevalence of flexor tendon grafting has decreased since the early part of this century, the technique isstill an important part of a hand surgeons armamentarium. Primary and staged flexor tendon grafting are appropriate techniques used to restore digital function after failed or neglected repairs. Appropriate patient selection, meticulous reconstructive techniques, and respect for basic biological principles of healing and repair are essential elements for successful tendon grafting.

手部创伤性骨关节缺损的处理

治疗手部骨关节缺损常采用植骨内固定、关节融合、关节成形及关节置换等方法．为总结经验，对１９８９年以来１０１例手部创伤性骨与关节缺损进行分析。单纯掌、指骨缺损３９例，行直接短缩对位，克氏针内固定６例，１例发主骨不连；对３３例缺损较大者用自体骨块植入克氏针交叉内固定，部分病例同时植人ＲＢＸ或异体骨粒，１０例发生延迟愈合，余全部正常愈合。骨与关节部分或完全缺损６２例，采用关节成形术４６例，其中以肋软骨移植效果最好，骨膜移植次之，筋膜衬垫或硅胶膜植入法较差；行关节融合术１１例．均达顺利融合；采用自体关节置换５例，均成活，术后关节活动度均＞７０°。我们认为：自体骨块植入克氏针交叉内固定，必要时植入ＲＢＸ骨粒．是治疗手部创伤性骨缺损的有效方法。关节缺损应按关节的重要性，分别采用关节融合术、关节成形术或关节置换术。     

心脏搭桥术对糖尿病人降糖治疗方案的影响

目的 :通过观察 型糖尿病 (DM- )行心脏冠脉搭桥术 (CABG)术后血糖水平的升高到恢复至术前状态的过程 ,从而判断 CABG对 DM- 降糖治疗的影响。方法 :选择 36例 DM- 合并冠心病病人 ,均于体外循环 (CPB)下行心脏搭桥术 ,从术前监测血糖 ,直至术后第七天 ,于术中及术后根据血糖水平适当应用胰岛素 ,观察其对降糖治疗效果及血糖趋于稳定的过程 ,从而判断 CABG对 DM- 血糖的影响。结果 :术中及术后 1～ 3d血糖会较术前明显升高 ,需加用胰岛素助降糖 ,术后 3d血糖渐降 ,第六天趋于稳定 ,第七天恢复至接近术前水平。结论 :DM- ,病人行 CABG术 ,只要围术期有效控制血糖 ,术后血糖基本会逐渐恢复至术前状态 ,对其今后的降糖治疗不会造成严重影响

目的总结冠心病患者行冠状动脉旁路移植术(CABG)和激光心肌血运重建术(TMLR)中的治疗难点、围术期处理要点,以提高冠心病患者的外科治疗效果。方法1997年5月~2006年1月,1405例冠心病患者中在体外循环下行CABG825例,其中单纯CABG666例,CABG+心瓣膜手术98例,CABG+室壁瘤手术55例,CABG+左心房粘液瘤摘除术2例,CABG+室间隔穿孔修补术2例,CABG+升主动脉成形术1例,CABG+纵隔内肿瘤切除术1例;非体外循环下CABG(OPCAB)500例;单纯TMLR30例,CABG+TMLR50例。结果每例移植旁路血管2.9±1.0支。住院死亡42例(3.0%),死亡原因包括出血、心肌梗死、低心排血量综合征、肾功能衰竭、多器官功能衰竭等。术后发生并发症70例,包括出血、低心排血量综合征、心肌梗死、肾功能不全等,均经积极的对症处理后治愈或好转。术前心绞痛(CCS)为~级的1177例患者中,术后1154例(98.0%)改善为0~级。术后随访857例(62.9%),随访时间8.3±2.9个月。随访6个月时788例(91.9%)无心绞痛发作,复查超声心动图提示:左心室射血分数0.66±0.10,较术前提高7.9%,生活质量较术前大为提高。结论CABG已成为治疗冠心病最有效的常规手术,只要能正确掌握适应证,有效地加强围术期管理,便可以扩大手术适应证范围,降低手术死亡率和并发症发生率,提高手术疗效。     

骨巨细胞瘤术后复发的手术治疗

目的:探讨骨巨细胞瘤术后复发的手术方法及疗效。方法:1994年6月-2003年10月,收治四肢长骨复发性骨巨细胞瘤18例,男12例,女6例;年龄18~44岁,平均26岁。股骨下端5例,胫骨上端8例,股骨上端1例,桡骨远端4例。Enneking分期:Ⅰa期14例,Ⅰb期4例。放射影像学Cam-panicci分级:Ⅰ级7例,Ⅱ级7例,Ⅲ级4例。病理学Jaffe分级:Ⅰ级8例,Ⅱ级7例,Ⅲ级3例。采用肿瘤扩大切除,吻合血管的自体腓骨、髂骨联合移植术治疗9例;瘤段切除,吻合血管的腓骨头移植重建术4例;瘤段切除,人工假体置换术5例。结果:随访时间11~110个月,平均66个月。所有移植骨术后均愈合,一侧关节间隙轻度狭窄2例,术后再复发1例。术后功能评价:优13例,良3例,可1例,差1例。结论:肿瘤扩大切除,吻合血管的自体腓骨、髂骨联合移植术既能彻底切除病变,又能保持和重建关节功能,是一种较理想的方法,Campanicci分级Ⅲ级、病理学Jaffe分级Ⅱ~Ⅲ级的复发性骨巨细胞瘤原则上应施行更为广泛的瘤段切除术,桡骨远端复发性骨巨细胞瘤因其部位的特殊性,应用自体腓骨移植重建效果良好。
