颈动脉切除术的临床研究

目的 探讨颈部恶性肿瘤侵犯颈总动脉和I或颈内动脉以及颌面部难控制大出血时对颈总动脉和颈内动脉的外科处理方法及其并发症、后遗症的预防。方法 回顾性分析1990年－2000年行颈总或I和颈内动脉结扎、切除术的6例临床资料。结果 本组均为男性，年龄17－66岁。其中颈部复发性转移癌浸润颈总动脉、颈内动脉3例，鼻咽癌放疗后颈部溃疡侵犯颈总动脉1例，上颌骨中央性血管瘤大出血1例，鼻咽纤维轿管瘤术中、术后大出血1例。单纯结扎、切除颈总动脉4例，颈总及颈内动脉同时结扎、切除2例。经随访，术后短暂性肢体偏瘫2例，脑梗塞、永久性偏瘫1例，无任何并发症3例。无手术死亡病例。结论 颈动脉切除术对已累及颈动脉的颈部恶性肿瘤是一种有效的治疗手段，对于颌面颈难以控制的致命性大出血是一种有效的急救措施。单纯切除颈总动脉所产生的术后并发症的发生率比颈总动脉和颈内动脉同时切除低；而已先期或同时切除颈外动脉，出现并发症的机会更大。术后酌用抗凝或溶栓药物对于脑血栓、脑梗塞的防治作用有待进一步研究。     

肝尾叶切除

肝尾叶深藏于肝门结构与下腔静脉之间，具有独立的管道系统，手术切除风险较大，作者结合２例肝尾叶切除的体会，复习文献，对肝尾叶的解剖、影像学特征、切除指征及手术方法进行了讨论。     

硬膜外腔阻滞对胸部手术应激反应的影响

目的 观察硬膜外腔阻滞对胸部手术应激激素和细胞因子的影响。方法20例食管癌手术病人,随机分为两组,每组10例,即全麻复令硬膜外腔阻滞(GEA)组和全麻(GA)组,分别测定麻醉诱导前、手术2h、手术4h、术毕、术后1d及术后3d的血浆去甲肾上腺素、肾上腺素、血清促肾上腺皮质激素(ACTH)、皮质醇、C-反应蛋白、IL-6及IL-10的水平。结果 血浆去甲肾上腺素和血清皮质醇GEA组术中术后无显著改变,但GA组术毕和术后1d显著升高(P<0.05),术后3d恢复至术前水平,组间比较前者有显著差异(P<0.05)。两组血浆肾上腺素、IL-10术中术后均无显著变化。两组血清ACTH、IL-6及CRP术中术后均显著升高(P<0.05),组间比较无显著差异。结论 硬膜外腔阻滞可以减轻胸部手术的应激反应。IL-6是较CRP更灵敏的反映组织损伤的炎性指标。     

门脉高压症断流术后上消化道再出血的外科治疗探讨

目的探讨门脉高压症断流术后上消化道再出血的外科治疗方法及其疗效.方法对(1999-2000)年本科收治的34例门脉高压症断流术后上消化道再出血的病人行外科治疗及疗效分析.其中肝功能Child A组10级,B级18例,C级6例.治疗前钡餐或胃镜检查确诊.结果有14例行非手术外科治疗,2例经药物治疗止血;4例行胃镜下食道静脉套扎(EVL)止血,效果较好;6例行食管胃底曲张静脉脉硬化剂注射,2例行三腔二囊管止血,疗效不确切,再出血率62.5%(5/8).20便行手术治疗,9例行肠腔分流,2例(2/9)术后再次发生上消化道出血;术中食管胃底曲张静脉缝扎1例,食管胃底曲张静脉硬化剂注射2例,术后均再次出现上消化道出血;贲门血管再次离断2例,改良食管下段横断术3例,术后近远期疗效均可;贲门周围血管离断加肠腔分流水2例,术后有1例上消化道再出血.结论胃镜下食道静脉套扎术在非手术止血中效果较好,适合于不不宜手术的病人.手术治疗常选肠腔分流.对前次断流不彻底需再次断流,再次断流门静脉压仍高,则考虑行断流加分流.

INDICATIONS FOR ENDOSCOPIC MUCOSAL RESECTION FOR EARLY COLORECTAL CANCER: SHOULD THEY BE STRICT OR SHOULD THEY BE EXPANDED?

Endoscopic technologies have been developed greatly. As for early gastric cancer, the indications for endoscopic mucosal resection for early colorectal cancer have been widened recently. Technological advances can support wider and deeper resections using endoscopy but the remaining problem for the endoscopic management of cancer is lymph node metastasis. I discuss here the indication for endoscopic mucosal resection for early colorectal cancer to bring into focus the risk factors for metastasis to lymph nodes.     

显微外科技术在尿道下裂修复中的应用

采用显微外科技术行阴囊纵膈皮瓣尿道下裂修复术18例，均获成功。其手术要点为：将阴茎腹侧纤维索条切除，充分伸展阴茎，皮瓣保留足够长度与宽度，克保血运；在显微镜下采用7－0尼龙丝线缝合，形成皮管，不缝皮肤，只缝皮下。硅胶管支架引流，加压包扎阴茎。本文对手术成功的原因进行了初步讨论。

Clinical and manometric evaluation of anorectal function following low anterior resection with low anastomotic line using an EEA™ stapler for rectal cancer

Anorectal function was evaluated in eight patients who had low anterior resection of the rectum with a low anastomotic line, using an EEA^™ stapler, with determination of function based on periodic manometric studies and clinical symptoms. Immediately following surgery all patients suffered from frequent bowel actions and soiling. These symptoms improved with time and most patients could enjoy almost normal daily life by the sixth postoperative month. One month after surgery, anal canal resting pressure and maximum squeeze pressure were significantly reduced and rectoanal inhibitory reflex was absent; neither showed a distinct tendency to improve thereafter. Rectal sensation and reservoir capacity, which also were seriously impaired, recovered satisfactorily by the time of the six-month examination. This suggests that an improvement of clinical symptoms following this operation is dependent upon the recovery of reservoir capacity and sensation of the neorectum, and that this operative procedure is a functionally acceptable option for low rectal cancer.
