Objective To summary the early experience of Dixon procedures with Da Vinci robotics surgical system for rectal cancer. Methods Eleven patients with rectal cancer underwent the combination of laparoscope and Da Vinci robotics surgical system with 4 trocars in our hospital from May. 2011 to Jan. 2012. Laparoscopy was firstly used to identify the possibility of the surgical procedure， then placed the 4 trocars， and maked sure the suspension of the sigmoid colon and the uterus. Transections of rectum were performed by a conventional laparoscopic method， and endoscopic separations were performed by Da Vinci robotics surgical system. The clinical data were retrospectively analyzed and the experience was summarized. Results The Da Vinci robotics-assisted Dixon procedures were successfully performed in 11 patients and no one turned to laparotomy. The operating time was 210-330min （mean 288.6min）；the blood loss was 20-100ml （mean 40ml）； The number of lymph nodes dissected was 12-21 per case （mean 13.9 per case）；the duration of bowel movement and hospital stay were 18-26h （mean 22h） and 7-16d （mean 11.5d）， respectively. There were no intraoperative or postoperative complications related to the use of robotics， and no residual cancer cells at resection margin. Conclusions Da Vinci robotics-assisted Dixion procedure with 4 trocars and suspension of sigmoid colon are safe and feasible， and it is beneficial to the recovery of patients
目的 探讨Mammotome切除乳腺纤维腺瘤的价值。方法 对我院2006年12月至2008年3月期间超声诊断为乳腺纤维腺瘤的107例患者共129枚病灶行超声引导下Mammotome旋切术。结果 129枚肿瘤超声显示完整切除，肿物切除时间5~40 min，平均16 min。1例发生血肿，3例皮下瘀血，2例乳头溢血，无一例感染。2例皮肤切割者以创可贴拉合后2 d愈合。病理结果显示124枚为良性病变，5枚为恶性。年龄≥40岁者共20例，其中恶性3例。超声显示有钙化灶者共6枚，其中3枚为恶性。103例获门诊随访，随访时间2～12个月，平均 5个月，超声发现2例复发。结论 Mammotome切除乳腺纤维腺瘤可同时达到诊断及治疗目的，美容效果好，对≥40岁及伴有钙化者要警惕恶性病变。
