Objective To compare the immediate therapeutic effects between endovenous laser treatment and conventional surgery for lower extremity varicosity. Methods Data of 350 limbs of 275 patients treated by endovenous laser treatment (endovenous laser treatment group) and 310 limbs of 210 patients by traditional surgery (traditional surgery group) were analyzed and compared in terms of operation time, number of the incision, postoperative pain, complications, postoperative hospitalized duration and 1-year recurrence rate. Results Endovenous laser treatment group had shorter operation time, fewer incisions, less postoperative pain and shorter postoperative hospitalized duration than traditional surgery group (Plt;0.05). The complications and 1-year recurrence rate had no significant differences between two groups (Pgt;0.05). Conclusion As a safe and effective new treatment for lower extremity varicosity with minimal invasiveness and no left scars, endovenous laser treatment has the potential to replace conventional surgery and extend the surgical indications for lower extremity varicosity treatment.
【摘要】 目的 評價在鼻煙壺及腕部行動靜脈造瘺術的療效。 方法 將2007年6月-2009年6月收治的156例腎功能衰竭患者隨機分成兩組，分別在鼻煙壺及腕部行動靜脈造瘺術，術后經彩色超聲隨訪其吻合口通暢情況，臨床觀察瘺管使用時間及其并發癥。 結果 術后隨訪2年，鼻煙壺處行動靜脈造瘺術的患者，瘺管術后1年初級通暢率及累積次級通暢率分別為76.9%、92.1%；術后2年初級通暢率及累積次級通暢率分別為57.9%、78.9%。而腕部組瘺管1年初級通暢率及累積次級通暢率分別為64.1%、81.3%；術后2年初級通暢率及累積次級通暢率分別為56.0%、76.0%。兩組在術后1年初級通暢率及累積次級通暢率差異有統計學意義（Plt;0.01），術后2年初級通暢率及累積次級通暢率差異無統計學意義（Pgt;0.05）。 結論 鼻煙壺處行動靜脈造瘺術的瘺管在短期內通暢率較腕部高，長期并無顯著性差異。【Abstract】 Objective To evaluate the effect of artificial arteriovenous fistula between tabatiere anatomique and wrist. Methods From June 2007 to June 2009, 156 cases of renal failure were randomly divided into two groups, and underwent artificial arteriovenous fistula on tabatiere anatomique or wrist, respectively. The patency of the anastomotic stoma was observed via B ultrasonography. Results The patients were followed up for two years postoperative. After the operation, the primary patency was 76.9% at the first year and 57.9% at the second year in tabatiere anatomique group; cumulative secondary patency was 92.1% at the first year and 78.9% at the second in tabatiere anatomique group; primary patency was 64.1% at the first year and 56.0% at the second in wrist group; cumulative secondary patency was 81.3% at the first year and 76.0% at the second year in wrist group. The primary patency and cumulative secondary patency were significantly different between tabatiere anatomique group and wrist group at the first year postoperatively (Plt;0.01) and not significant at the second year postoperatively (Pgt;0.05). Conclusion Prophase patency of tabatiere anatomique is higher than that of wrist. There was no significant difference between them in a long term.
Objective To evaluate the effectiveness and safety of early enteral nutrition (EN) versus total parenteral nutrition (TPN) after pancreaticoduodenectomy (PD). Methods Such databases as MEDLINE, EMbase, The Cochrane Library, CBM, VIP, CNKI were electronically searched to collect the randomized controlled trials (RCTs) about EN versus TPN after PD published from 2000 to March 2010. The quality of the included trials was assessed according to the inclusive and exclusive criteria, and the data were extracted and analyzed by using RevMan 5.0 software. Results A total of 4 RCTs involving 322 PD patients were included. The meta-analysis showed that the EN (the treatment group) was superior to the TPN (the control group) in the average postoperative hospital stay (MD= –2.34, 95%CI –3.91 to –0.77, Plt;0.05), the total incidence rate of complication (RR=0.75, 95%CI 0.57 to 0.99, P=0.04), the recovery time of enterocinesia (MD= –29.87, 95%CI –33.01 to –26.73, Plt;0.05) and the nutrition costs (MD= –30.51, 95%CI –35.78 to –25.24, Plt;0.05); there were no differences in mortality (RR=0.23, 95%CI 0.03 to 2.03, P=0.19), pancreatic leakage (RR=0.78, 95%CI 0.45 to 1.35, P=0.38), infectious complications (RR=0.71, 95%CI 0.43 to 1.18, P=0.19), non-infectious complications (RR=0.78, 95%CI 0.5 1 to 1.20, P=0.26) and postoperative serum albumin level (MD= –0.79, 95%CI –2.84 to 1.27, P=0.45). Conclusion Compared with total parenteral nutrition, the enteral nutrition used earlier after pancreatoduodenectomy shows significant advantages. But more reasonably-designed and double blind RCTs with large scale are expected to provide high quality proof.
