上尿路梗阻性急性肾功能不全内、外引流的选择

目的探讨内、外引流在上尿路梗阻急性肾功能不全时的选择和效果。方法25例各种原因引起的上尿路梗阻（15例肿瘤性梗阻,10例非肿瘤性梗阻）合并急性肾功能不全,分别或先后对12例行输尿管内置双J管（doub le J,D J）内引流15次,对19例行经皮肾穿刺造瘘（percutaneous nephrectomy,PCN）外引流23次。结果引流成功23例,PCN外引流成功率86.9%（20/23）,双J管内引流成功率60.0%（9/15）,PCN术后继发出血1例。结论对于盆腹腔进展期或广泛转移肿瘤导致的梗阻,PCN解除梗阻优于输尿管支架内引流;非肿瘤性梗阻宜先尝试D J内引流。     

腹腔镜胆囊切除术中腹腔引流管的应用体会

目的：总结腹腔镜胆囊切除术（laparoscopic cholecystectomy,LC）中腹腔引流管的临床应用经验。方法：回顾分析2001年1月至2006年6月1650例LC患者的临床资料。结果：1650例中1487例（90.1%）术中未放置腹腔引流管,恢复顺利,放置腹腔引流管的163例中159例（97.5%）引流管无明显液体引出,或仅有少量腹腔冲洗液,术后24～48h拔除,康复好,4例患者术后发生胆漏。结论：应严格掌握放置腹腔引流管的指征,多数LC术中不放置腹腔引流管是合理可行的,更有利于患者的康复。     

Fallopian tube malignancies: experience of Social Security Agency Aegean Maternity Hospital

The aim of the study was to determine the clinical characteristics and management of fallopian tube malignancies together with the results there unto that had been diagnosed and treated in our oncology department retrospectively. Twelve cases of fallopian tube malignancies, of a total of 2155 gynecologic malignancies (0.55%), that had been diagnosed in or referred to our hospital between January 1986 and December 2001 were evaluated retrospectively. Eight of 12 cases were diagnosed after surgical intervention in our department. Staging laparotomies were applied to all of the eight cases. Complementary surgeries of other four cases who were referred to our department were done according to the same principles of cytoreductive surgery. Staging of the cases was done according to Federation of International Gynecologists and Obstetricians (FIGO). Adjuvant chemotherapy was applied to all of the cases except two (10 cases, 83.3%). Second-look laparotomy (SLL) was applied to two of the cases. Mean age of the cases was 54.2 (range 35-72) years. Histopathology of the cases was as follows: serous adenocarcinoma in 10 cases (83.3%), endometrioid adenocarcinoma in one case (8.3%), and undifferentiated carcinoma in one case (8.3%). Adjuvant chemotherapy (PAC regimen to eight of the cases and PP regimen to two cases) was applied to 10 of the cases (83.3%). SLL was applied to two cases. Another case had died because of local recurrence at the 27th month of the follow-up. Mean follow-up period of the cases was 37.8 months (range 1-144 months). Fallopian tube malignancies are very rare malignancies. Diagnosis can be made generally peri- or postoperatively. More extensive clinical research must be performed in order to have definite etiologic, diagnostic, management modalities, and prognostic markers.     

输尿管镜技术治疗梗阻性急性肾功能衰竭(附13例报告)

目的探讨输尿管镜技术在治疗急性梗阻性肾功能衰竭的应用。方法在输尿管镜直视下置DJ管治疗由结石、血块及晚期盆腔肿瘤引起的急性梗阻性肾功能衰竭13例。结果术后2-7d肾功能恢复正常，无术后并发症。血肌酐和尿素氮均在正常范围，尿量正常。结论应用榆尿管镜技术治疗急性梗阻性肾功能衰竭是一种安全、有效、微创的方法。     

管扎式结肠肛管吻合术治疗低位直肠癌(附256例报告)

目的:评价管扎式结肠肛管吻合术治疗低位直肠癌的安全性和临床效果.方法:回顾性分析1991年10月至2005年12月共256例低位直肠癌行管扎式结肠肛管吻合术的临床资料.结果:无手术死亡,术后发生吻合漏1例,吻合口狭窄16例,术后肛门功能优良率96.7%,术后5年肿瘤局部复发13.1%,5年存活率为71.9%.结论:该法具有操作简单易行安全可靠,减少了吻合口漏的发生,适用于各级医院开展.     

环隙气升式反应器在非牛顿流体体系中的应用──反应器特性研究和体积氧传递系数的关联

以羧甲基纤维素钠（ＣＭＣ）水溶液模拟非牛顿型发酵介质，在内径为０．１５ｍ，高为０．９７５ｍ的环隙气升式反应器内，考察了液体流变性质和导流筒结构对气液传质的影响，提出了体积氧传递系数（ＫＬａ）的经验关联式。实验表明：对于较高粘度的假塑性流体，反应器内部采用整体式导流筒结构，将有利于传质和混合，其性能优于采用开窗式导流筒或无导流筒的反应器。     

Chest wall implantation of lung cancer at the drainage tube site: Report of a case

We report herein the case of a 70-year-old man in whom a chest wall implantation of adenocarcinoma of the lung at the drainage tube site was found 4 months after a right lower lobectomy with mediastinal lymph node dissection had been performed for adenocarcinoma of the right lower lobe. The lesion was successfully treated by tumor extirpation. We believe that tumor seeding to the chest wall occurred at the time of thoracotomy. To prevent such tumor seeding, the pleural cavity should be washed out routinely with a massive volume of physiological saline solution prior to closure of the chest wall.
