Tracheal surgery

Surgical resection and reconstruction of the trachea can be performed both for benign and malignant diseases. The main indications for surgery include inflammatory (generally post-intubation), congenital or post-traumatic stenoses, degenerative lesions, benign or malignant neoplasms. Success can be pursued only by accurate patient selection and timing, meticulous surgical techniques, careful follow up and, when required, multidisciplinary cooperation. Although surgical resection has now become part of our surgical practice, other treatment modalities are approaching a new clinical application era, in particular tracheal transplantation and bioengineering. These new techniques will certainly offer, in the near future, improved chances to treat difficult cases

Partial purification and MALDI-TOF MS analysis of UN1, a tumor antigen membrane glycoprotein.

UN1 is a membrane glycoprotein that is expressed in immature human thymocytes, a subpopulation of peripheral T lymphocytes, the HPB acute lymphoblastic leukemia (ALL) T-cell line and fetal thymus. We previously reported the isolation of a monoclonal antibody (UN1 mAb) recognizing the UN1 protein that was classified as "unclustered" at the 5th and 6th International Workshop and Conference on Human Leukocyte Differentiation Antigens. UN1 was highly expressed in breast cancer tissues and was undetected in non-proliferative lesions and in normal breast tissues, indicating a role for UN1 in the development of a tumorigenic phenotype of breast cancer cells. In this study, we report a partial purification of the UN1 protein from HPB-ALL T cells by anion-exchange chromatography followed by immunoprecipitation with the UN1 mAb and MALDI-TOF MS analysis. This analysis should assist in identifying the amino acid sequence of UN

Report of a Case of Video-Assisted Thoracoscopic Resection of Bronchogenic Cyst Developed in the Aorto-Pulmonary Window

We report the case of a 28-years-old male with a bronchogenic cyst developed in the aorto-pulmonary window. Left video-assisted thoracoscopy was performed and the cyst was removed intact and completely. Operative time was 48 minutes. The postoperative course was uneventful and the patient was discharged on the third postoperative day. We believe that an uncomplicated mediastinal bronchogenic cyst can be successfully approached by video-assisted thoracoscopy. In the case of an intraparenchymal or complicated cyst, thoracoscopic resection can be technically difficult and hazardous, and open approach is preferable

Policies and reporting guidelines for small biopsy specimens of mediastinal masses

目前，胸腺恶性肿瘤治疗方案大多是根据术\ud 后病理确定，然而，多数临床治疗决策需要在术前\ud 通过活检小标本的病理报告来制定。所以，术前活\ud 检小标本的正确获取和病理解读对治疗决策的制定\ud 显得非常重要[1]。这些标本包括细针活检标本，带\ud 芯穿刺活检标本和手术切取活检标本[2-7]。由于胸\ud 腺肿瘤的病理诊断对组织的获取方法和获取量都有较高\ud 的要求，加之对病理的描述也没有统一的标准，使得小\ud 标本在诊断胸腺瘤方面存在诸多问题。为此，ITMIG在\ud 病理科医生和外科医生回顾相关文献和提出初步建议的\ud 基础上，经集体讨论制定了活检规范操作流程，提出了\ud 对纵隔肿物小活检标本处理和病理报告的建议。旨在为\ud 术前患者的治疗提供一个统一和具有循证医学证据的方\ud 法；同时，将有利于全球数据之间的比较和开展合作研\ud 究，充分利用医疗资源

Deep venous thrombosis and abortion: an unusual clinical manifestation of severe form of pectus excavatum

Pectus excavatum is a chest wall malformation with a strong psychological and aesthetic impact. Rarely, pectus excavatum patients can show respiratory or cardiac symptoms occurring mainly during physical exertion. We report a case of a 34-year-old pregnant woman with a severe degree of pectus excavatum who developed serious cardiovascular disease resulting in spontaneous twin abortion at the twenty-first week of gestation. Cardiovascular disease was resolved after open surgical correction of pectus excavatum. This case shows how a tardive diagnosis and a delayed surgical approach for pectus excavatum can lead to severe consequences

Long-term results of laryngotracheal resection for benign stenosis from a series of 109 consecutive patients

OBJECTIVES: Long-term results of patients undergoing laryngotracheal resection for benign stenosis are reported. This is the largest series ever published. METHODS: Between 1991 and March 2015, 109 consecutive patients (64 males, 45 females; mean age 39 ± 10.9 years) underwent laryngotracheal resection for subglottic postintubation (93) or idiopathic (16) stenosis. Preoperative procedures included tracheostomy in 35 patients, laser in 17 and laser plus stenting in 18. The upper limit of the stenosis ranged between actual involvement of the vocal cords and 1.5 cm from the glottis. Airway resection length ranged between 1.5 and 6 cm (mean 3.4 ± 0.8 cm) and it was over 4.5 cm in 14 patients. Laryngotracheal release was performed in 9 patients (suprahyoid in 7, pericardial in 1 and suprahyoid + pericardial in 1). RESULTS: There was no perioperative mortality. Ninety-nine patients (90.8%) had excellent or good early results. Ten patients (9.2%) experienced complications including restenosis in 8, dehiscence in 1 and glottic oedema requiring tracheostomy in 1. Restenosis was treated in all 8 patients with endoscopic procedures (5 laser, 2 laser + stent, 1 mechanical dilatation). The patient with anastomotic dehiscence required temporary tracheostomy closed after 1 year with no sequelae. One patient presenting postoperative glottic oedema underwent permanent tracheostomy. Minor complications occurred in 4 patients (3 wound infections, 1 atrial fibrillation). Definitive excellent or good results were achieved in 94.5% of patients. Twenty-eight post-coma patients with neuropsychiatric disorders showed no increased complication and failure rate. CONCLUSIONS: Laryngotracheal resection is the definitive curative treatment for subglottic stenosis allowing very high success rate at long term. Early complications can be managed by endoscopic procedures achieving excellent and stable results over time
