目的 总结术后早期炎性肠梗阻的临床特点及诊治经验。方法 回顾性分析我院2004年1月至2010年12月期间收治的22例腹部手术后早期炎性肠梗阻患者的临床资料。结果 全组均行保守治疗，均治愈出院。肠梗阻解除时间平均6.5d。2例出院后再次出现慢性肠梗阻，经保守治疗好转。结论 术后早期炎性肠梗阻在腹腔严重感染性疾病术后多见，治疗以保守治疗为主，同时应动态观察腹部症状、体征变化，严防误诊、误治。
【摘要】 目的 探讨建立局部性家兔肠系膜静脉血栓（MVT）模型的方法。 方法 于2008年1月，将36只家兔随机均分为3组，肠系膜前静脉局部阻断加静脉分支注射凝血酶，A组80 U/mL，B组40 U/mL，C组注射生理盐水1 mL。观测血栓形成时间、范围和周围静脉血D-二聚体（DD）变化。 结果 A、B两组均可建立控制范围内稳定MVT模型，血栓形成时间分别为（15.6±2.0） min和（22.3±2.5）min，两组比较有统计学意义（Plt;0.001）；术前A、B两组DD为（68.4±5.7）ng/mL、（72.7±6.4）ng/mL，血栓形成后为（209.0±24.0）ng/mL、（215.4±17.6）ng/mL，组内比较有统计学意义（Plt;0.001）；C组不形成血栓。 结论 局部静脉阻断加凝血酶注射法可建立稳定和范围可控的MVT模型，建模前后血浆DD值有一定实验参考价值。【Abstract】 Objective To establish the model of local mesenteric venous thrombosis (MVT) in rabbits. Methods In January 2008, 36 rabbits were randomly divided into three groups with 12 rabbits in each. The anterior mesenteric veins were blocked regionally, and at the same time the rabbits were injected with thrombin 80 U/mL through the branches of mesenteric vein in group A, 40 U/mL in group B, and 1 mL normal saline in group C. Time and range of thrombosis were observed, and D-dimer level in peripheral vein was tested. Results Stable MVT model was established in intended region in both group A and B. There was a significant reduction of thrombosis time in group A [(15.6±2.0) minutes] when compared with that in group B [(22.3±2.5) minutes] (Plt;0.001). The levels of D-dimer in group A two hours after operation [(209.0±24.0) ng/mL] increased significantly compared with that before the operation [(68.4±5.7) ng/mL](Plt;0.001); while the same condition was found in group B [(215.4±17.6) ng/mL vs (72.7±6.4) ng/mL] (Plt;0.001). No thrombus was found in group C. Conclusion Stable MVT model with controllable thrombotic range can be established by regional vein blockade plus thrombin injection. Plasma D-dimer levels before and after model establishment could be as a parameter for assessing the experiment.
Objective To analyse the causes of missed diagnosis in colorectal cancers and improve the early diagnosis. Methods A retrospective analysis was made to investigate the cause of missed diagnosis in 380 cases suffering from colorectal cancers.Results Of the 1 020 patients treated in our hospital in the past ten years (1984-1993), 380 patients were missed diagnosed, with the missed diagnosis rate of 37.3%. The main causes included: ①lacking attention to the early symptoms of colorectal cancers, neglecting the need to conduct certain tests such digital rectal examination and stool occult blood examination, ②delaying of seeking medical advice on the part of the patients, ③being satisfied with the diagnosis and treatment of benign disease, and ④neglecting certain special tests such as enteroscopy and barium enema examination of colon.Conclusion Routine use of rectal touch, occult blood examination and necessary use of special tests such as enteroscopy, barium enema examination of colon in patients suffering from stool change will increase the rate of accurate diagnosis of colorectal cancer.
目的 探讨先天性胆总管囊肿(congenital choledochal cyst,CCC)术式选择与疗效的关系。方法 对1989年至1998年间38例CCC手术治疗病例进行回顾性研究。结果 38例中行胆肠Roux-Y吻合术20例，肝总管十二指肠高位大口吻合术18例。术后随机获随访31例。13例胆肠Roux-Y吻合术后随访3～7年，发现5例并发十二指肠溃疡，3例并发胆道逆行感染。18例肝总管十二指肠高位大口吻合术后随访2～5年，发现1例并发胆道逆行感染，无1例并发十二指肠溃疡。结论 由于肝总管十二指肠高位大口吻合术后远期并发十二指肠溃疡发生率较低，其与胆肠Roux-Y吻合术相比，是提高CCC患儿术后远期生活质量较理想的术式。
目的探讨术后早期肠梗阻的临床特点、诊断及治疗。方法对10例术后早期肠梗阻患者进行回顾性分析。结果10例均为机械性肠梗阻。保守治疗6例，其中治愈5例，死亡1例； 手术治疗4例，其中3例术中有绞窄性肠梗阻征象，均治愈。1例术中发现为广泛癌性粘连，行部分粘连松解术，术后第8天再发肠梗阻，保守治疗1天无效，患者自动出院。结论术后早期肠梗阻诊断并不困难； 保守治疗多数有效，故宜先行保守治疗； 可疑肠绞窄时应及时中转手术。

Objective To investigate the anatomic foundation of using main branch of posterior femoral nerve to restore the sensation function of distal basedsural island flap. Methods Thirty cases of adult human cadaver legs fixed by 4%formaldehyde were used. Anatomical investigation of the posterior femoral nerves of lower legs was conducted under surgical microscope to observe their distribution, branches and their relationship with small saphenous vein. Nerve brancheswith diameter more than 0.1 mm were dissected and accounted during observation.The length and diameter of the nerves were measured. Results The main branch of posterior femoral nerve ran downwards from popliteal fossa within superficial fascia along with small saphenous vein. 70% of the main branch of the posterior femoral nerves lay medially to small saphenous vein, and 30% laterally. They wereclassified into 3 types according to their distribution in lower legs: typeⅠ (33.3%) innervated the upper 1/4 region of lower leg (region Ⅰ), type Ⅱ (43.3%) had branches in upper 1/2 region (region Ⅰ and Ⅱ), and type Ⅲ (23.3%) distributed over the upper 3/4 region (region Ⅰ, Ⅱ and Ⅲ). In type Ⅱ, the diameter of the main branches of posterior femoral nerves in the middle of popliteal tossa was 10±04 mm and innervated the posterior upper-middle region (which was the ordirary donor region of distal based sural island flaps) of lower legs with 2.0±0.8 branches, whose diameter was 0.3±0.2 mm and length was 3.5±2.7 mm. The distance between the end of these branches and small saphenous vein was 0.8±0.6 mm. In type Ⅲ, their diameter was 1.2±0.3 mm and innervated the posterior upper-middle region of lower legs with 3.7±1.7 branches, whose diameter was 0.4±0.1 mm and length was 3.7±2.6 mm. The distancebetween the end of these branches and small saphenous vein was 0.8±0.4 mm. Conclusion 66.6% of human main branch of posteriorfemoral nerves (type Ⅱ and type Ⅲ) can be used to restore the sensation of distal based sural island flap through anastomosis with sensor nerve stump of footduring operation.
Objective To discuss the strategies for building the framework of team culture of multi-disciplinary team (MDT) for colorectal cancer. Methods By comprehending the traditional concept of volunteer and probing into the value of traditional team culture, combining the needs of MDT for colorectal cancer, build appropriate team culture and core idea of MDT for colorectal cancer. Results Confirm that building of volunteers groups and the volunteers culture is the core of the team culture of MDT for colorectal cancer. Analyze characters of volunteers groups and the operation strategies, and find the way of maintaining the volunteers culture. Conclusion With the development of volunteers groups and increased participants, the team culture of MDT for colorectal cancer will show more sociality and extent. And it is also the important idea and direction for development in future. As team culture, organization structure and personnel structure supplements each other, adjusting and perfecting the team culture in practice continually is a long-term work for MDT.
