鼻部源性突眼的CT分析

目的：为了提高对鼻部源性突眼的认识。材料和方法：本文19例鼻部源性突眼，其中鼻咽癌7例，鼻咽纤维血管瘤2例，鼻腔纤维血管瘤、恶性肉芽肿和嗅神经母细胞瘤各1例，上颌窦癌和软骨肉瘤各2例，上颌窦恶性肉芽肿、纤维肉瘤和恶性纤维组织细胞瘤各1例，全部病例均作轴位CT扫描，12例加作增强扫描，详细分析了它们CT表现。结果：源于鼻咽的放疗前鼻咽癌和纤维血管瘤，其病变主要位于鼻咽腔和咽旁，后者显著增强并有钙斑，与前者不同；源于上颌窦的肿瘤，病变占据上颌窦的全部或大部分，软骨肉瘤有钙斑且无强化，易与其它肿瘤区别，它们破坏上颌窦顶部进入眼眶；鼻腔嗅神经母细胞瘤在鼻腔和筛窦形成肿块，破坏筛骨眶板侵入眼眶。结论：根据CT所见，可判断突眼原因。     

Nasal fractures in children

Summary A group of thirty children with nasal fractures was evaluated retrospectively by means of a questionnaire and hospital records. Age at the time of injury ranged from age 3 to 12 (mean = 8.6) years and mean follow-up period was 9 years. Eight patients reported some degree of nasal obstruction post reduction, but only one patient required submucous resection and two patients underwent septorhinoplasty for appearance. No patients reported class III malocclusion, or required orthodontic treatment or maxillofacial corrective surgery for maxillary hypoplasia. We concluded that a childhood nasal fracture treated by closed reduction does not have deleterious effects on facial or nasal growth.This work was supported in part by the Brigham Surgical Group Foundation, Inc., Boston, Massachusetts, USA     

上下泪小管同时断裂35例手术分析

目的探讨上、下泪小管同时断裂的手术治疗方法。方法上、下泪小管同时断裂共35例,按手术方式分为两组。A组:27例同时行上、下泪小管吻合术;B组:8例仅行下泪小管吻合术。结果A组27例较少发生内眦角变形、睑外翻,上下泪点复位良好。结论为求上、下泪小管断裂术后能达到解剖复位及功能复位,同时行上、下泪小管断裂吻合效果较好。     

Self-expandable metallic stents in the treatment of post-esophagogastrostomy/post-esophagoenterostomy fistula

Esophageus or gaster resection in patients with malignant disease is still a treatment of choice. It is obvious that each surgical procedure in these patients carries some possibility of complications. Esophageo-gastric or esophageo-jejuno anastomosis has a 4-27% frequency of fistula occurrence. All these result in 65% mortality in cases of poorer prognosis. The aim of this paper is not to present all types of complications but to objectively analyse the usefulness of the covered stent placement in the treatment of anastomotic fistulas. We present six patients who were treated for postoperative fistula of esophageo-gastric anastomosis (1 case) or esophageo-jejuno anastomosis (5 cases). All patients were treated with stapler suture for digestive tract reconstruction after malignancy removal during the primary surgical procedure. Signs and symptoms of suture leak between 5-8 days post-surgery were observed. Conservative therapy was not effective. Thus a new method of treatment was employed - covered stent placement. The procedure was performed under X-ray control. In all treated patients there was change for the better and quick reduction of secretion from the fistulas was observed. All patients were discharged from the department after several days and all had survived at 30 days follow-up. Covered esophageal stent placement seems to be a safe and promising method of treatment for patients with anastomotic fistula which significantly reduces mortality and improves quality of live. Our experiences confirms that of other investigators.     

Quality of life after total mesorectal excision for rectal cancer

BACKGROUND: After total mesorectal excision for rectal cancer, many surgeons try to avoid an abdominoperineal resection (APR) by performing a transanally double stapled low colo-rectal anastomosis (LRA), frequently without a pouch. This policy is mainly based on the assumption that the quality of life after such LRA is higher than after APR. It has been suggested that a better functional outcome and therefore a higher quality of life might be achieved by a colo-anal J-pouch anastomosis (CPA). The aim of this study was to assess quality of life among disease-free survivors after APR, LRA and CPA. METHODS: The charts of 301 consecutive patients who had undergone surgery for cancer in the middle or lower third of the rectum were analysed. Two hundred four patients were eligible for inclusion. The quality of life among these patients was assessed using one generic (EQ-5D) and two disease-specific questionnaires (EORTC QLQ-C30 and EORTC QLQ-CR38). RESULTS: The response rate was 82%. The median follow-up was 31 months. Overall, quality of life was good but CPA patients had better quality of life scores than APR and LRA patients. This difference was not only due to the better functional outcome but also to the lower incidence of disturbed micturition and sexual problems in the CPA group. CONCLUSION: The quality of life after colo-anal J-pouch anastomosis is better than after abdominoperineal resection (APR) and low colo-rectal anastomosis (LRA). The quality of life after APR is similar to that after LRA.     

周围神经端侧动脉套接后神经再生的研究

目的研究周围神经端侧动脉套接后神经再生的可能性及其特点. 方法取SD大鼠75只,在股骨中下段切断腓神经,将近断端逆转90度包埋于肌肉中.随机分为5组.A组:将截取的左颈总动脉套接于右侧正常胫神经侧方与腓总神经远端2 mm距离之间,缝合部胫神经外膜不予切除;B组:在胫神经套接部外膜开窗1.0 mm;C组:腓总神经切断14天后再予动脉套接,余同B组;D组:同B组,且于动脉套接部注入神经生长因子(neural growth factor, NGF)1 ml;E组:将腓总神经远端以端侧缝合形式直接缝合于胫神经的一侧,外膜开窗1.0 mm.术后4、8和12周分别行组织学、电镜和神经纤维计数等检查. 结果 4周时C、D及E组周边区域有神经纤维轴突和髓鞘再生,A组则无神经纤维生长; 8周时C、D及E组再生神经纤维较B组多,E组神经纤维较C、D组多,差异有统计学意义(P<0.05); 12周时C、D及E组神经纤维多于B组,差异有统计学意义(P<0.05);C组及D组有较丰富的神经再生,与神经端侧直接吻合的E组差异无统计学意义(P>0.05). 结论神经端侧2 mm距离动脉套接可作为修复周围神经损伤的一种可行方法.

再次显微输卵管复通术17例报道

对17例人工绝育后曾行输卵管复通手术失败病例,进行再次显微输卵管复通手术,经随访二年以上,宫内妊娠率41.18%(7/17)。手术后成功率与输卵管吻合部位有关,峡部与壶腹部吻合效果最差。作者指出再次显微输卵管吻合手术对由于原吻合部位闭锁病例有一定的价值。但需慎重考虑如何提高初次吻合术质量、防止术后粘连是十分重要。
