  • Minimally Invasive Surgical Techniques in Obstructed Colorectal Cancer

    ObjectiveTo investigate the value of different minimally invasive surgical techniques, stent placement, laparoscopic surgery, and sustained-releasing 5-fluorouracil, in solving intestinal obstruction due to colorectal cancer. MethodsFrom May 2000 to May 2010, total 68 patients with obstructed colorectal cancers in three centers were treated in two ways in terms of the stage: The first, patients with resectable tumors underwent colorectal stent placement as a ‘bridge to surgery’ guided by enteroscope under X-ray. After clinical decompression and bowel preparation, laparoscopic radical resection was performed. The second, patients with unresectable tumors underwent rectal stent placement just for palliation. Sustained-releasing 5-fluorouracil was implanted into the local cancerous intestinal tract through stent walls. ResultsFifty-one of 52 patients underwent laparoscopic radical resection successfully following stent placement, while one failed and died during follow-up 93 d postoperatively. Forty patients with successful laparoscopic surgery were followed up in 3 to 36 months (with an average of 15 months) without tumor planting in the incision, postoperative local recurrence or anastomotic stricture. Fifteen unresectable patients and one high-risk, intolerable patient underwent rectal stent placement and implantation of sustained-releasing 5fluorouracil. During follow-up 3 to 24 months (with an average of 14 months), 11 died, who survived for (350±222) d (range 101-720 d), and 5 were still alive for 3 to 13 months (with an average of 9 months) without intestinal obstruction. ConclusionsLaparoscopic surgery combined with stent placement is an effective and safe procedure for resectable obstructed colorectal cancer. For unresectal obstructed rectal cancer, rectal stent placement combined with sustained-releasing 5-fluorouracil can prolong survival time avoiding colostomy.

  • Litmus Paper and Fibrin Sealant Help Prevent Potential Pancreatoenterostomy Leakage (Report of 47 Cases)

    目的总结降低胰十二指肠切除术后胰空肠吻合口漏发病率的经验体会。 方法切除胰头后,将胰腺残端游离2.5~3.0 cm,利用红色石蕊试纸遇碱性胰液变蓝的特性,帮助寻找胰腺断面被横断的小导管,丝线贯穿缝扎。将空肠袢断端2.0~2.5 cm浆肌层剥除后施行套叠式胰空肠端端吻合,距浆肌层游离缘1.0~1.5 cm 处空肠上下壁各缝1针固定,最后用纤维蛋白胶封闭吻合口。结果47例患者中无一例发生胰空肠吻合口漏。结论该法操作较简便,适用于胰腺残端各种情况的处理。
