??Surgical treatment of inverted nipple WEN Bing??XIE Kun. Department of Plastic Surgery, Peking University First Hospital??Beijing 100034,China

Abstract The basic principles of inverted nipple correction surgery are adequate release of fibrous bands pulling the nipple retraction and nipple substrate support tissue reconstruction. The most commonly used corrective surgery includes breast tissue flap method and areola dermal flap method. In recent years, acellular allograft dermal matrix or artificial dermis filling method as a new simple minimally invasive corrective surgery has better prospects. 相似文献

??Objective To investigate the characteristics of indirect injury of periodontal membrane caused by maxillofacial impact injury. Methods The study was carried out at the laboratory of oral and maxillofacial trauma in Fourth Military Medical University??from November 2013 to January 2014. Totally 18 dogs were divided equally into six groups with random allocation??the right mandible of each dog was impacted by a cylindroid iron cap whose weight was 0.26kg??but teeth were not injured directly??the animals were killed 6 h??24 h??3 d??7 d??2 wk and 4 wk later??respectively??the histopathologic manifestations of periodontal membrane of the fourth premolar of right mandible??the second premolar of right mandible and the second premolar of left mandible were observed. Results The injury of periodontal membrane of the fourth premolar of right mandible was relatively obvious??but the pathologic changes were reversible??periodontal membrane of the second premolar of right mandible was injured slightly??yet no obvious histopathologic change could be observed in periodontal membrane of the second premolar of left mandible. Conclusion Maxillofacial impact injury can cause indirect injuries of periodontal membrane of adjacent teeth??but the pathologic changes are reversible??traumatic severity decreases as the distance of the tooth to the wound area increases. 相似文献

Abstract Objective To investigate the oncologic efficacy of laparoscopic-assisted radial total gastrectomy ??LATG?? for Siewert type ?? and ?? adenocarcinoma of the esophagogastric junction (AEG). Methods The clinicopathalogical data of 418 patients with Siewert type ?? and ?? AEG who had undergone radical total gastrectomy between December 2008 and June 2013 in Fujian Medical University Union Hospital were analyzed retrospectively. The short and long term outcomes were compared between the LATG (n=342) and opened radial total gastrectomy ??OTG?? (n=76) groups. Results The clinicopathological characteristics between the two groups had no statistical difference. LATG compared with OTG was associated with shorter operative time??less blood loss??shorter time to the resumption of a semi-fluid diet and shorter hospital stay. However, postoperative complication rates between the two groups had no significant difference. The 3-year overall survival rate in the LATG group was significantly higher than that in the OTG group (71.1% versus 61.1%??P=0.033). In stratified analysis according to Siewert classification??the LATG group demonstrated significantly higher 3-year overall survival rate (79.5%versus 69.1%??P=0.010) for Siewert type ?? AEG compared with the OTG group??however??in the Siewert type ?? AEG subgroup??the 3-year overall survival rates were similar (P=0.315). COX proportional hazards regression model indicated that the surgical approach and TNM stage were independent prognostic factors affecting the whole group??P<0.05??. Conclusion LATG is a safe and feasible procedure with better short-term outcomes for Siewert type ?? and ?? AEG. For Siewert type ?? AEG particularly??LATG may yield better long-term survival. 相似文献

Abstract Objective To study vascular pattern of inferior mesenteric artery (IMA) by CT angiography (CTA) for colorectal operation. Methods Seventy-seven patients with colorectal carcinoma underwent preoperative IMA CTA from January 2011 to April 2013 in the First Affiliated Hospital of Dalian Medical University were selected randomly. IMA and its branches were reconstructed by VR-r AV technique and divided into different categories. Results All the patients’ IMA branched off the abdominal aorta. Four types of branching were confirmed. Type A, where the three arteries branched off from the same point; Type B, where SA branched off from LCA; and Type C, where SA branched off from SRA; Type D, where SA branched off from LCA and SRA respectively. There was no statistical relation between typing and age, gender, invasive depth of tumor, lymph node metastasis, distance from tumor to anus. But lymph node metastasis had significant associated with the distance from tumor to anus (P=0.002). Conclusion Aberrance of IMA is various, metastasis of 242 group lymph nodes was associated with aberrance of SA. Performing preoperative IMA-CTA is helpful to preserve LCA and reduce inadequate lymph node dissection. 相似文献

??Objective:To evaluate the clinical merit of contrast??enhanced ultrasound (CEUS) in the diagnosis of Small hepatocellular carcinoma (HCC) in patients with posthepatitic cirrhosis. Methods:Small hepatocellular carcinoma were examined and observed by CEUS between March 2004 and October 2005,using ultrasound contrast agent??Sonovue.Contrast enhanced CT and or MRI were performed in all cases. Results:The accuracy of diagnosing Small HCC by CEUS were 88.2% (60/68),according to the hypo??enhancement in arterial phase,iso??enhancement or hyo??enhancement in portal phase,hypo??enhancement in delayed phase.The accuracy and false positive rate of diagnosing Small HCC by CEUS were 97.1% (66/68) and 2.9%(2/68) according to the hypo??enhancement in delayed phase. Conclusion:CEUS might increase the diagnosis of small HCC. 相似文献

??Objective:To evaluate the clinical characteristics of leiomyosarcoma of inferior vena cava and to summarize the experience on the treatment of leiomyosarcoma of the inferior vena cava. Methods:The clinical data of 14 patients with leiomyosarcoma of inferior vena cava admitted between 1986 and 2006 in the General Hospital of PLA was analyzed retrospectively. Results:The diagnosis of the 12 patients was certained by pathology.Eleven cases were resected successfully with necessary reconstruction of inferior vena cava and only one patient was performed laparotomy.Two patients were not operated because of distant metastases. Conclusion:The en bloc resection with necessary reconstruction of inferior vena cava is an effective method to treat leiomyosarcoma of inferior vena cava. 相似文献
