超声引导下VacoraTM旋切系统的实验研究

目的探讨VacoraTM真空辅助活检系统的准确性和安全性,为临床应用奠定基础。方法选用里脊肉和鱼丸作为实验材料,根据鱼丸大小将实验分为5组:0.5、0.8、1.0、1.5及2.0cm组,每组鱼丸3~5个。采用VacoraTM活检系统,先行灰阶超声扫查肌肉后将鱼丸置入肌肉中,超声扫查置入的鱼丸,同轴套管针在超声引导下插入鱼丸底部,在套管针引导和超声监视下行旋切真空抽吸术;旋切后取出采样腔内的组织标本,用超声检查肌肉内的残腔,确定无鱼丸残留声像图。结果每次旋切组织条比较完整,其大小为20.0mm×0.6mm,旋切次数随鱼丸大小的增加而增加;0.5、0.8、1.0、1.5及2.0cm组里脊肉内鱼丸全部切除的平均旋切次数分别为12、15、19、26和31。所用的平均时间分别为15、18、23、27和34min。结论VacoraTM真空辅助活检系统定位准确、取样完整、操作简便。可为良恶性病变的诊断提供足够量的病理检查标本,为良性病变的完全切除提供具有潜在价值的手段。     

Laparoscopic Medial-to-lateral Colon Dissection: How and Why

Laparoscopic colectomy is a difficult procedure with a long learning curve. We describe in this study our technique for right- and left-sided laparoscopic medial-to-lateral colectomy. The medial approach involves division of the vascular pedicle first, followed by mobilization of the mesentery toward the abdominal wall, and finally freeing of the colon along the white line of Toldt. This approach allows immediate identification of the plane between the mesocolon and the retroperitoneum and renders the dissection fast and safe. Our series of 50 consecutive laparoscopic colectomies supports this concept. We believe that surgeons familiar with this technique will have an important tool in their armamentarium to circumvent some of the challenges of laparoscopic colectomy.     

单蒂横行腹直肌肌皮瓣乳房再造中Ⅳ区皮瓣的取舍

目的探讨单蒂横行腹直肌肌皮瓣乳房再造术中Ⅳ区皮瓣的取舍。方法通过16例实施单蒂横行腹直肌肌皮瓣乳房再造术，术中观察皮瓣的皮色、断面出血颜色，并利用近红外血氧监测仪测定皮瓣各区的组织血氧饱和度，决定Ⅳ区皮瓣的取舍。术后观察指标包括术后并发症及美学效果。结果16例中5例Ⅳ皮瓣的肤色正常、断面出血呈鲜红色而非暗红色、组织血氧饱和度不低于Ⅲ区组织血氧饱和度的95％。在接受了保留Ⅳ区皮瓣的单蒂横行腹直肌肌皮瓣乳房再造术后，再造乳房全部成活，无严重术后并发症，患者对再造乳房均很满意。结论近红外血氧无创检测有助于决定Ⅳ区皮瓣的取舍。有选择地实施保留Ⅳ区皮瓣的单蒂横行腹直肌肌皮瓣乳房再造术，可用于大面积胸壁缺损或乳腺尾叶的修复重建。     

包膜囊上再置乳房假体隆乳术

目的探究隆乳术后包膜囊挛缩的手术治疗方法。方法采用原切口(腋窝顶或乳房皱襞下)，对隆乳后包膜挛缩者采用包膜囊保留并在其浅层再置人假体的方法进行治疗。结果治疗12例14侧乳房包膜囊挛缩症均取得良好效果。结论保留挛缩的包膜囊并在其浅层置人假体的乳房假体包膜囊挛缩治疗术具有创伤小、出血少、操作简便、安全性高、复发率低、并可通过腋窝顶小切口完成等优点，是治疗乳房假体包膜囊挛缩的较好方法。     

Short term correlates of the Neuro Emotional Technique for cancer-related traumatic stress symptoms: A pilot case series

Introduction As many as one quarter of all cancer survivors report traumatic stress symptoms from cancer-related experiences. While the majority of these patients do not meet the criteria for posttraumatic stress disorder (PTSD), there is growing evidence that subsyndromal symptoms can significantly contribute to functional impairment and negative health outcomes. Treatment options for the hallmark symptoms of traumatic stress—unpleasant, intrusive thoughts and avoidant behaviors—have not been well investigated for the cancer survivorship population. Materials and methods Seven female cancer survivors with traumatic stress symptoms from cancer-related experiences and no other major psychopathology, were enrolled to receive three sessions of Neuro-Emotional Technique (NET), a brief, targeted treatment that combines traditional desensitization principles with complementary modalities. Results Psychological outcome measures (Impact of Event Scale (IES) and Subjective Units of Distress (SUD) and physiological measures (Heart Rate (HR) and Skin Conductance Level (SCL) demonstrated the following changes: 71% on IES, 88% SUD, 74% on HR, and 65% on SCL following the intervention. Statistically significant changes were observed for all four parameters, and effect size g for proportion improved were 0.50 each for IES, SUD, and HR, and 0.20 for SCL. Conclusions These cases suggest feasibility of the NET intervention for cancer-related traumatic stress and the potential for change in symptoms and physiological reactivity. Further investigation is needed to determine the specific and long-term effects of such an approach. Implications for cancer survivors Traumatic stress from cancer-related experiences might represent a constellation of symptoms that are amenable to brief, targeted interventions.

Preference for donor site scar orientation in pedicled latissimus dorsi breast reconstruction

A survey was carried out to ascertain the preference for donor site scar orientation in patients undergoing pedicled latissimus dorsi breast reconstruction and their views on breast reconstruction in general. One hundred twelve women (59 Chinese, 53 Western) completed the questionnaire. Participants were asked to state their preferred scar orientation (i.e., oblique, horizontal, or vertical) based on photographs showing the position of the scars. Demographic information and views on issues surrounding breast reconstruction in general were also collected. Data was analyzed non-parametrically with chi-square test and t test. The mean age of participants was 39.5 years (20–73 years). Seventy-seven percent of the participants would opt for an immediate breast reconstruction if offered (p < 0.001). Eighty-six percent would have objection to the use of silicone implant as a whole or part of a reconstruction (p < 0.001). Vertical and horizontal scars were the preferred orientation, with no women choosing the oblique orientation as their first choice (p < 0.001). The non-Chinese of 40 years or older, as well as Chinese women from all age groups, preferred the horizontal scar (p < 0.05). We demonstrated that both culture and age impact on the preferred scar orientation in breast reconstruction. Women in the age group we commonly reconstruct favored the horizontal scar. However, the younger women of non-Chinese origin tended to favor the vertical scar.     

Mammaplasty: Shape,volume, and scar size

Recently many mammaplasty techniques have been presented with special attention paid to the resulting scar's size and its position. The surgeon should try to hid the scar, and if the inverted T incision is used, its horizontal branch should be as short as possible and kept in the breast area. Neverthelss, excessive concern about the final scar size should not interfere with the final results of the mammaplasty as far as shape, volume and lasting results are concerned. The author presents his experience in mammaplasty with respect to the volume, the shape, and the scar size interrelationships.     

老年人微小病变性肾病综合征的临床特征和长期随访

探讨老年人微小病变性(MC)特发性肾病综合征(PNS)的临床特征及预后。方法 观察成人MC性PNS118例,其中老年患者18例,占15.2％。结果 发现老年患者NS的临床表现与成年组相似;但血尿发病率较低,22％比38％;高血压和肾功能不全的发病率明显增高,38.9％比16％和33.3％比19％(P<0.01)。老年组对激素治疗的敏感性略差;但NS复发率明显减少,11.1％比43％。结论 尽管NS的复发和对激素依赖使治疗有一定困难,但激素、细胞毒性药物和环孢素A对于消除蛋白尿,延缓肾功能不全是有助的。     

Breast augmentation with silicone implants: the role of surgical drainage—report on 502 consecutive patients

Breast augmentation is one of the most frequently performed cosmetic surgery procedures worldwide. We report on a series of 502 consecutive cosmetic breast augmentations by a single surgeon, using both the submuscular and submammary approaches. A vacuum drain was placed in the surgical pocket at the end of the procedure. The drain fluid collection was recorded immediately after the surgery and the following day before removal. A tenfold increase in the amount of fluid collection was noted in the drain’s reservoir. Thirteen patients presented with minor wound healing problems at the second postoperative follow-up, which were treated conservatively; two of them had the implant removed and replaced after 2 months. There were only two capsular contractions at 1-year follow-up. We focus our discussion on the drainage in the early postoperative period and conclude that the routine use of a surgical drainage reduces the risk for complications. Based on our findings, we advocate that short-term routine use of a surgical drain is advisable.
