后腹腔镜治疗肾上腺肿瘤35例临床分析

目的总结后腹腔镜技术治疗肾上腺肿瘤的临床经验.方法采用后腹腔镜切除肾上腺肿瘤35例,男12例,女23例.年龄25岁～72岁,平均49.8岁.左侧15例,右侧20例.其中嗜铬细胞瘤5例,原发性醛固酮增多症10,柯兴氏病2例,神经节细胞瘤2例,无功能性腺瘤16例.腰部取3个套管针穿刺入路,用自制的水囊扩张器扩张后腹腔,用超声刀将肿瘤切除.结果 35例手术均成功,无中转开放手术病例.术中出血量10～500 ml,平均74 ml.病人均未输血.手术时间45～200 min,平均90 min.结论后腹腔镜手术切除肾上腺肿瘤手术效果确切,手术时间短,术中出血少,损伤小,术后恢复快,可以替代绝大多数肾上腺肿瘤开放手术.     

回盲部恶性肿瘤的诊治

目的：分析回盲部恶性肿瘤的诊断和治疗过程，总结经验．以期提高早期确诊率和患者生存率。方法：回顾性分析近5年53例住院治疗的回盲部恶性肿瘤患者的临床资料。结果：53例患者中腺癌、黏液腺癌50例，恶性淋巴瘤3例。首次确诊率为75．5％。误诊或延迟诊断的疾病主要为阑尾炎、阑尾脓肿，胆囊炎、胆石症、下消化道出血、贫血待查等。结论：60岁以上的老年患者为回盲部恶性肿瘤的主要人群，肿瘤类型主要为腺癌。尽管首发症状缺乏特异性，但提高警觉性，详细询问病史，通过大便隐血试验、钡灌肠或气钡双重造影、纤维结肠镜检查仍能有效的提高首次确诊率，积极手术冶疗，可显著改善患者的预后。     

Treatment of acute cerebral infarction with PGI2--evaluating the clinical effect and observation of dynamic changes in plasma TXB2 and 6-keto PGF1 alpha levels

18 patients with acute cerebral infarction were randomly subdivided into two groups: PGI2-treated group (11 cases) and low-molecular-weight Dextran-treated group (7 cases). Dosage of PGI2 was 2-5 ng/kg/min intravenous drip. Infusion was started within 72 hours after the onset of symptoms. The data showed that the plasma 6-keto-PGF1 alpha levels were increased, the plasma TXB2 levels, MAR as well as the scores of neurological deficit were decreased in the PGI2-treated group. The clinical improvement in PGI2-treated group is better than that in the dextran-treated group.

胃粘膜癌前病变的形态定量研究——胃粘膜核腺比值的定量分析

应用自动化图象分析仪对131个胃粘膜肠型病灶(单纯性肠化27个;异型增生:轻度30,中度35个,重度20个;肠型胃癌19个)进行定量分析。以单个腺管内细胞核总面积与细胞面积之比(ING)作为反映细胞核大小、数量及覆层排列程度的客观定量指标。结果发现:单纯性肠化(对照组)0.165±0.025,轻度异型增生0.21±0.023,中度异型增生0.259±0.026,重度异型增生0.32±0.028,分化型胃癌0.371±0.052,各组ING值呈正态,各组间的均值有非常显著的差异(P<0001)。因而,ING可作为胃粘膜癌前病变诊断的指标。

Liver and lung resection for colorectal metastasis

Aim: To examine the survival benefit of liver and lung resection for colorectal metastasis and the potential prognostic factors that affect patient survival. Methods: All patients who had resection of lung or liver metastasis for colorectal metastasis in Queen Elizabeth Hospital, Hong Kong from 1995 to 2004 were retrospectively reviewed. The overall and disease‐free survival was analysed, in particularly between liver and lung metastasis. All factors that may have affected the survival were entered into Cox's proportional hazards regression model to identify significant variables associated with survival. Results: At 5 years, the overall survival of patients who had resection of lung and liver metastasis was 44% and 38%, respectively; the disease‐free survival was 26% and 24%, respectively. Overall and disease‐free survival of patients with resection of lung metastasis was comparable to those with resection of liver metastasis. The differentiations of primary tumour and time to metastasis were shown to be significant prognostic factors influencing overall survival. Those patients with systemic chemotherapy after resection of colorectal metastasis demonstrated a significantly higher probability of overall survival. Conclusion: Resection of lung and liver metastases from colorectal origin was safe and both procedures improved survival. The use of chemotherapy after resection of metastasis significantly improved the overall survival.
