  • Primary Duodenal Adenocarcinoma

    Objective To improve the diagnosis and treatment of primary adenocarcinoma of the duodenum. MethodsLiteratures were reviewed.ResultsThe morbidity of primary duodenal adenocarcinoma was low and its clinical manifestation had no characteristics.The most effective methods in the diagnosis of the disease were gastrointestinal radiography and endoscopy with the accuracy of 88% and 89% respectively.The disease could be cured by resection of the lesion. The selection of operative type depended on the stage and position of the tumor.Radical resection and tumor stage played an important role in the prognosis.Conclusion Early diagnosis and rational operation are the major ways to improve the resectability and to modify the therapeutic result.

  • ADVANCES IN EPIDEMIOLOGIC STUDY OF PRIMARY LIVER CANCER

    ObjectiveTo study the epidemiologic characteristics of primary liver cancer (PLC). MethodsThe literatures about regional distribution and etiologic epidemiology of PLC were reviewed. Results PLC was mainly distributed on caostland in the south-east of China. The main cause of PLC was hepatitis B virus, aflatoxin and contamination of drinking water. Otherwise, PLS was also related with lack of some trace element, sex horemones, genealogy cause and so on.Conclusion The genesis of PLC was by multiple factors.

  • Laparoscopic Surgical Treatment of Primary Retroperitoneal Tumor (Report of 12 Cases)

    目的探讨原发性腹膜后肿瘤行腹腔镜手术的安全性和疗效。 方法回顾性分析新疆医科大学第二附属医院普外科2008年4月至2013年4月期间行腹腔镜手术治疗的12例原发性腹膜后肿瘤患者的临床资料。 结果12例患者均行腹腔镜手术,其中1例中转开腹手术,其余行腹腔镜手术成功。平均手术时间190 min,术中平均出血300 mL,术后平均8.5 d出院。术后左下肢深静脉血栓形成1例,经保守治疗好转。围手术期无死亡患者。术后病理类型:良性肿瘤5例,其中神经鞘瘤1例,脂肪瘤1例,腹膜后囊肿2例,畸胎瘤1例;恶性肿瘤7例,其中纤维肉瘤2例,平滑肌肉瘤1例,恶性淋巴瘤2例,脂肪肉瘤2例。良性肿瘤平均直径8.1 cm,恶性肿瘤平均直径5.6 cm。随访7例恶性肿瘤患者,平均随访时间13个月,无复发及转移。 结论通过本组有限的病例资料初步得出,原发性腹膜后肿瘤的诊断主要依靠影像学检查。对于肿瘤直径≤10 cm的良性肿瘤或直径≤6 cm的恶性肿瘤且未侵犯主要血管者行腹腔镜手术治疗安全、可行。

  • TREATMENT WITH RIGID CHOLEDOCHOSCOPE THROUGH HEPATIC LEFT LATERAL LOBE FOR PRIMARY CHOLANGIOLITHIASIS

    Thirty patients of primary cholangiolithiasis were treated by the use of a rigid choledochoscope passing through the left lateral liver lobe for removal. 20 cases of them were manipulated with mini-incisions, the stones in 14 patients (70.0%) were completely removed. In the remaining 10 cases of conventional laparotomy, left lateral liver incised in 4, left lateral lobectomy in 6 before rigid choledochoscopic lithotomy; the stons were completely removed in eight patients (80.0%). No case had complications, the short-term effect of the method is obviously better than that of other various operative treatments. It has the advantages of less trauma, less pain, and quick recovery. It is a economical and effective new technique and has prospects of application.

  • Ultrasonography Features of Primary Thyroid Non-Hodgkin Lymphoma

    Objective To investigate ultrasonography features of primary thyroid non-Hodgkin lymphoma (PT-NHL). Methods Ultrasonographic data of patients with PT-NHL(PT-NHL group) and non-Hodgkin lymphoma (control group) who were treated in our hospital from May. 2002 to Jul. 2014 were collected and analyzed. Results Compared with control group, enhancement of posterior echoes was more common in PT-NHL group (P=0.000), and difference values of transverse diameters, anteroposterior diameters, and sagittal diameters of more involved lobe to another lobe were bigger(P < 0.05), but echo pattern of gland, ultrasonographic classification of lesions, classification of vascularity, and condition of cervical lymph nodes were found no statistical difference(P > 0.05). In patients with nodular-type lesions(37 patients in PT-NHL group and 12 patients in control group), length of nodule lesions was larger in PT-NHL group (P=0.000), but there was no statistical difference in shape, boundary, orientation, and echoes of nodules between 2 groups(P > 0.05). In Pulsed-Wave(PW) Doppler between 2 groups(17 patients in PT-NHL group and 4 patients in control group), vascular resistance index(RI) was higher in PT-NHL group than those of control group (P=0.024). Conclusion The enhancement of posterior echoes was a feature in ultrasonography images of PT-NHL. Asymmetrical volume, high value of RI, and big nodule might link to PT-NHL, but diffuse heterogeneous echo with hypoechoic lesions might result in wrong diagnosis as PT-NHL.

  • SEX HORMONE AND PRIMARY LIVER CANCER

    The serum level of testosterone (T), estradiol (E2) and progesterone (P) in 86 cases with primary liver cancer (PLC) (male:76 cases; female:10 cases) was determined by RIA method. The result showed that for male cases, serum level of T and ratio of T/E2 in operation group and nonoperation group was significantly higher than that in benign hepatic diseases group (BHD group) and normal control group (NC group), but the value of E2 obviously lower than the later two groups. After tumor resection, the level of E2 increased, while serum level of T and value of T/E2 decreased, which had no significant difference as contrasted with BHD group and NC group. The serum level of T,E2 in female PLC group made no difference to BHD group and NC group, but the value of T/E2 much higher than NC group. No obvious changes of the serum level of progesterone can be observed in both male and female cases. Our research showed that high serum testosterone level and low estradiol level may be concerned with PLC. The possibility and importance of sex hormone imbalance on initializing and developing of PLC is suggested.

  • EXPRESSION AND ASSOCIATION OF P16 AND P53 PROTEIN IN GALLBLADDER CARCINOMA

    Objective To study the association and the effect of the expression of p16 and p53 protein on the occurence and development of gallbladder carcinoma. Methods The expression of p16 and p53 protein were detected in 40 cases of gallbladder carcinoma with immunohistochemical method. Results The expressions of p16 and p53 protein were closely correlated to the tumor pathological grade, lymph mode metastasis and prognosis. p16 protein was correlated to the Nevin classifications. Conclusion The results indicate that the low expression rate of p16 protein occurred in the advanced stage of gallbladder carcinoma. The expression of p16 and p53 protein are helpful in judging the malignant degree and prognosis of primary gallbladder cancer.
