    Notes: Abstract  Background: Neural reorganization occurs in porcine vein grafts and placement of an external stent reduces graft occlusion. Aim of the study: To determine the effect of external stenting on the innervation of porcine vein grafts. Methods: Saphenous vein into carotid artery grafting (with and without external stents) was performed in 16 pigs. After one and six months, grafts were removed, nerves were counted, and neointima was assessed. Results: In vein graft compared to ungrafted vein, there was a significant (p 〈 0.05) decrease in medial perivascular nerves, but a dramatic increase in paravascular nerves in the adventitia (p 〈 0.05). In stented vein grafts there was also a reduction of perivascular nerves and the paravascular nerve proliferation observed in vein grafts at one month was inhibited (p 〈 0.05). Neointima formation and the appearance of large paravascular nerve bundles in the adventitia of vein grafts were abolished by external stenting. Conclusions: Neural reorganization plays a role in vein-graft failure, possibly through the local release of mitogens; the prevention of this reorganization contributes to the inhibitory effect of the external stent on neointima formation.

    Notes: Background : Azathioprine therapy is discontinued in one-third of patients with inflammatory bowel disease because of toxicity or a lack of clinical response. Patients with thiopurine methyltransferase (TPMT) deficiency are intolerant to azathioprine, whilst carriers are at increased risk of side-effects.Aim : To evaluate the importance of TPMT activity in the management of azathioprine therapy in inflammatory bowel disease.Methods : Clinical response, adverse effects and haematological parameters were determined and correlated with TPMT enzyme activity and genotype in 106 patients with inflammatory bowel disease.Results : Ninety-six patients had high TPMT activity, and 10 had intermediate activity. Nineteen patients (18%) were intolerant to azathioprine. Fifteen (16%) of those with high TPMT activity were intolerant, compared with five (50%) with intermediate activity [odds ratio (OR), 5.4; 95% confidence interval (CI), 1.5–19.8]. Complete remission was achieved in 63% of cases, and complete or partial remission in 79%. Interestingly, very high TPMT activity (〉 14 units/mL red blood cells) was significantly associated with non-response, irrespective of the time on azathioprine (OR, 0.21; 95% CI, 0.07–0.68). TPMT gene mutations correlated with TPMT activity.Conclusions : Inflammatory bowel disease patients with intermediate TPMT activity have an increased risk of azathioprine toxicity. Conversely, very high TPMT activity predicts treatment failure. TPMT genotype predicted TPMT phenotype in this study.

    Description / Table of Contents: Summary Off-pump coronary artery bypass grafting (CABG) has been shown to be a valuable alternative to conventional procedures with the use of cardiopulmonary bypass (CPB). Recent investigations clearly demonstrated that off-pump CABG could avoid complement activation and could reduce the release of cytokines, in particular interleukin (IL)-8, which may in turn limit the activation of leukocytes and endothelial cells, resulting in less postoperative myocardial injury. By inhibiting complement and cellular activation, the extent of postoperative inflammatory response to off-pump surgery is greatly reduced. To further explore the underlying mechanisms, future studies may not only enhance the benefits of off-pump surgery but also improve our current CPB management. Pharmacological strategies such as steroid administration before CPB and increasing biocompatibility of CPB materials through the use of heparin-coated circuits may be well applied in the clinical setting.
    Notes: Zusammenfassung Off-pump-Koronararterien-Bypass-Verlegung (CAGB) hat sich als wertvolle Alternative zu den konventionellen Verfahren des kardiopulmonalen Bypasses (CPB) erwiesen. Neue Studien haben eindeutig gezeigt, daß off-pump CABG die komplementäre Aktivation vermeiden konnte, und auch die Freisetzung der Zytokine, insbesondere des Interleukin (IL)-8, welche seinerseits die Aktivierung der Leukozyten und der Endothelzellen eingrenzen könnte, was weniger postoperative Myokardschäden bedeutet. Zukünftige Studien der verantwortlichen Mechanismen werden nicht nur die Vorteile der off-pump-Chirurgie noch deutlicher machen, sondern auch unser jetziges CPB-Management verbessern. Pharmakologische Strategien, z.B. die Verabreichung von Steroiden vor CPB und eine Erhöhung der Biokompatibilität von CPB-Materialien durch mit Heparin-beschichteten Oberflächen, werden wohl im klinischen Bereich Anwendung finden.

    Notes: Abstract. A 68-year-old Chinese male with a history of renal cell carcinoma presenting with increasing shortness of breath and hemoptysis was found to have subtotal left main bronchial obstruction secondary to a metastatic endobronchial tumor. The mass was completely resected through a rigid ventilating bronchoscope, and a silicone stent was placed over the tumor bed in the left main bronchus. He remained asymptomatic with no evidence of bronchoscopic recurrence 4 months after the procedure. Obstructive endobronchial metastases from nonpulmonary primaries are rare. Endoluminal resection with stent placement can provide good palliation in this group of patients with limited survival.

    Notes: Abstract Background: We review our experience in video-assisted thoracoscopic surgery (VATS) on patients over 75 years of age from a single institution. Methods: From September 1992 to November 1995, 22 patients (13 males and 9 females with mean age of 78.1 years) underwent the following procedures: pleural biopsies with or without drainage and decortication (5), drainage of empyema (2), wedge lung biopsy (3), bullectomy and talc insufflation (1), major lung resections (5), mediastinal biopsy (1), pericardiectomy (3), and thymectomy (2). Pulmonary function tests of the entire group showed the mean forced expiratory volume in 1 s (FEV1) to be 1.46 1 (range 0.63–2.11) and forced vital capacity (FVC) to be 2.04 (range 0.98–3.55) 1. Results: There was no mortality. Morbidity included prolonged chest drainage over 7 days in two patients (9.1%), one of whom was discharged with a drainage bag. Particularly of note was the lack of postoperative pulmonary complications. Conclusions: We conclude that VATS in the elderly population is safe. Age alone should not be a contraindication for major lung or mediastinal surgery.

    Notes: Abstract Background: Video-assisted thoracoscopic surgery (VATS) is now an established approach in the management of many thoracic conditions. However, the high cost of this new technology has deterred many Asian hospitals from widely applying this technique. Methods: This article describes our strategies to reduce cost in our practice of VATS over the last few years. Results: VATS involves (1) careful patient selection, (2) use of conventional thoracic instruments as much as possible, (3) modification of conventional instruments, (4) limited use of expensive consumables, and (5) development and application of endoscopic suturing technique. Conclusions: VATS is still in evolution. Cost containment, while desirable in the West, is a high priority in Asia if this new surgical approach is to be applicable even in developing countries. More research is greatly needed in this area.

    Notes: Abstract. It is generally thought that simultaneous bilateral chest surgery carries a high morbidity. We reviewed the results of simultaneous (under one anesthesia) vs staged bilateral video-assisted thoracoscopic surgery (VATS) from a single institution over a 35-month period. From September 1992 to July 1995, we performed simultaneous bilateral VATS on 37 patients (31 males, six females, age ranging from 15 to 55 years) with spontaneous pneumothorax (20) for bleb resections and pleurodesis; thoracodorsal sympathectomy (12) for palmar hyperhidrosis and vasospastic disease; and metastatic sarcomas (five) for wedge lung resections. During the same period, nine patients with metachronous bilateral spontaneous pneumothorax had staged procedures, as did two with digital ischemic ulcers for sympathectomy and three with metastatic pulmonary osteosarcomas for resection. Mean postoperative hospital stays in days for the simultaneous groups were 3.3 for spontaneous pneumothorax, 2.1 for sympathectomy, and 1.5 for wedge resection, compared to 2.9, 2.5, and 2.2 for the staged groups, respectively (p 〉 0.05 by Mann-Whitney U tests). Likewise, pain assessment by visual analogue scale as well as analgesic requirement showed no significant difference between the simultaneous and the staged groups. We conclude that simultaneous VATS is not associated with increased morbidity or prolonged hospital stay compared to the staged counterparts and provides an attractive alternative to the median sternotomy, bilateral posterolateral thoracotomy, or transternal (clam-shell) thoracotomy for selected cases of simultaneous bilateral lung surgery.
