腹腔镜下经腹部和后矢状路联合修补术后复发性直肠尿道瘘和直肠阴道瘘

目的介绍腹腔镜下经腹部和后矢状路联合手术治疗直肠肛门手术后复发性直肠尿道瘘和直肠阴道瘘。方法5例术后多次复发性直肠尿道瘘或直肠阴道瘘患儿，男3例，女2例，年龄3～13岁。腹部在腹腔镜下游离结肠，远端尽可能从骶前向盆腔分离肠管，近端肠管游离保证正常结肠能无张力拖至肛门处吻合。低位盆腔肠管分离通过后矢状位切口（肛缘后上1cm），正中切开直肠后壁，直肠内剥离黏膜至齿状线，直视下修补瘘口，近端切断结肠，将正常结肠拖出与肛门吻合。结果所有患儿排便功能良好，仅1例有轻度污粪，未见瘘管复发。结论腹腔镜下经腹部和后矢状路游离结肠、直肠，创伤小，视野清晰，避开了粘连紧密的瘘管分离，完整结肠拖出避免了瘘管的复发，后矢状路直肠切开能直视下显示并修补瘘管。     

Preoperative staging of gastrointestinal tumors by endosonography

Summary Intracavitary application of ultrasound was first performed for diagnostic purposes in 1967; since that time, it has been more and more widely used. As far as the gastrointestinal tract is concerned, endoscopically controlled ultrasonic probes provide visualization of the various layers of the intestinal wall. It is therefore possible to describe lesions of the esophagus, stomach, and the rectum with regard to their nature and depth of infiltration. Furthermore, periesophageal and perigastric organs can be visualized. It has become evident that endosonography is particularly important for pretherapeutic staging of tumors of the esophagus, stomach, and rectum. Here prospective comparative studies confirm the superiority of this new diagnostic procedure when compared to the methods available to date.     

直肠肛管恶性黑色素瘤的临床特征分析

目的了解原发性直肠肛管恶性黑色素瘤的临床特点。方法回顾性分析9例原发性直肠肛管恶性黑色素瘤的临床资料,并复习文献。结果直肠肛管恶性黑色素瘤以女性多见,平均发病年龄56岁,病程5.8个月;首发症状以血便为最常见,其次为肛门肿物突出。94.7%的直肠肛管恶性黑色素瘤在距离肛缘5.0cm范围内;肿瘤最大径(3.3±2.1)cm;其中54.5%可活动;有19.1%的肿瘤表面光滑;6.6%的肿瘤质地软;14.0%同期发现转移,肝转移最常见,腹股沟淋巴结转移其次;的病例出现误诊,超过者被误诊为良性疾病;手术治疗中以Miles术为主,经肛门局部切除术其次。结论直肠肛管恶性黑色素瘤极易误诊。手术治疗为主。

低位直肠癌保肛手术后发生吻合口漏的原因及处理

目的：探讨低位直肠癌保肛术后吻合口漏的原因及合理有效的防治方法。方法：对我院近10年来出现的低位直肠癌全系膜切除低位吻合手术后吻合口漏的发生及治疗情况进行回顾性分析。对吻合口漏的患者采用手术及保守治疗（骶前双腔管冲洗引流加肛管引流）。结果：共行低位保肛手术348例,术后发生吻合口漏11例,吻合口漏的发生率为3.2%。患者的年龄、吻合技术和肿瘤组织学分型与吻合口漏的发生无关。而患者的性别、肿瘤的大小与吻合口漏的发生密切相关（P〈0.05）。11例患者中有3例行手术治疗（HA手术）,8例采用保守治疗后均痊愈出院,吻合口漏发生至出院时间平均为10～15d。结论：充分的术前准备和良好的吻合技术是防止吻合口漏发生的关键。正确判断吻合口漏的发生及采用正确的处理方法是治疗的前提,双腔引流管加肛管引流是保守治疗吻合口漏的有效方法。     

Surgical relevance of diagnostic imaging techniques in pretherapeutic staging of carcinoma of the esophagus, stomach, colon and rectum

Summary. The increasing spectrum of therapeutic options for tumors of the gastrointestinal tract has resulted in a refinement of the pretherapeutic diagnostic strategies. The diagnostic approach in surgical institutions that are focused on primary surgical resection will therefore be much less sophisticated than in institutions who propose a selective therapeutic approach based on the pretherapeutic tumor stage and prognostic parameters. Pretherapeutic assessment of the depth of tumor infiltration, i. e. the T-category, is essential because most further diagnostic and therapeutic decisions are based on this information. This can today be achieved with a high degree of accuracy by endoscopy and endoscopic ultrasonography. Early T-stages (T1–2) are usually an indication for primary surgical resection and, after exclusion of distant metastases, no further diagnostic studies are required. In patients with locally advanced esophageal, gastric or rectum tumors (T3–4) multimodal therapeutic concepts should be considered. This usually requires additional diagnostic studies. None of the available diagnostic imaging modalities today allows satisfactory pretherapeutic assessment of lymph node metastases. The assumed nodular status should therefore currently not influence therapeutic decisions. Essential is, however, the assessment of distant metastases, since the documentation of distant tumor spread will change the therapeutic approach to a palliative situation. Detailed histologic and molecular-biologic assessment of tumor characteristics is growing in importance. This not only provides therapeutically relevant information regarding tumor grading, but opens the door towards a modern molecular diagnostic approach. It can be expected that in the near future a vast amount of relevant prognostic information can be obtained from endoscopic tumor biopsies, which may soon alter our therapeutic concepts.      

直肠印戒细胞癌和粘液腺癌临床病理分析

目的：比较研究直肠印戒细胞癌和粘液腺癌临床和病理学特点的差异。方法：回顾性地对比分折20例直肠印戒细胞癌和同期79例直肠粘液腺癌的临床和病理学特点。结果：直肠印戒细胞癌组的一年生存率65．0％，三年生存率30．0％，五年生存率5．0％。黏液腺癌组一年生存率84．8％，三年生存率58．2％，五年生存率38．0％。两在显微镜下黏液分布不同，肉眼所见大体标本相差甚远。结论：直肠印戒细胞癌较直肠粘液腺癌的诊断困难，恶性度高，预后差，临床上应对二区别对待，术中冰冻切片有助于提高病理诊断准确率，从而指导手术。     

内镜黏膜下剥离术治疗直肠类癌

目的探讨内镜黏膜下剥离术（ESD）治疗直肠类癌的应用价值。方法肠镜发现直肠黏膜下肿块后进行微探头超声检查，对诊断为类癌者应用头端弯曲的针形切开刀进行内镜黏膜下剥离术治疗：（1）黏膜下注射生理盐水抬高病灶，使病灶与肌层分离；（2）预切开病灶周围黏膜；（3）剥离病变下方黏膜下层结缔组织，完整切除病灶。结果5例直肠类癌患者，肿瘤直径0.4～1.2（平均1．1）cm，均成功完成ESD治疗。ESD手术时间（自黏膜下注射至完整剥离病变）20-45（平均35）min；术中创面少量出血，均经电凝、氩离子血浆凝固和止血夹成功止血。不需再次肠镜下止血。1例剥离深至肌层，出现皮下气肿，保守治疗好转。术后全部经病理确诊。基底和切缘未见病变累及。1个月后肠镜复查，创面基本愈合。结论ESD是治疗直肠类癌的新方法．以往需要外科手术切除的肿瘤通过ESD可以达到同样的治疗效果。
