    Notizen: Abstract Background: Major airway obstruction due to benign or malignant etiology is not uncommon and is always distressing. Intraluminal stenting has been shown to be a safe and effective approach for symptomatic relief in selected patients based on the European and North American experience. Methods: We reviewed our experience in Hong Kong on airway stenting over a 19-month period. Results: From February 1994 to August 1995, 33 silicone stents (Dumon stent, Cometh, Marseille, France) were placed in 23 patients (20 males, three females with mean age 61.4 years, range from 26 to 81). Eighteen stents were placed in the trachea, nine in the left main stem, five in the right main stem, and one Y-stent over the carina. Twelve patients had esophageal carcinoma involving the airway, seven had bronchial carcinoma, one had metastatic carcinoma, and three had benign strictures (of which two were due to tuberculosis). There was no procedural related mortality. Stent migration occurred in four patients (17%) and required stent change. Symptoms were improved in all patients as documented by the visual analogue scale. Conclusion: Our experience represents the ``stentable'' diseases seen in Hong Kong, where carcinoma of the esophagus (and tuberculosis) remains prevalent. We conclude that intraluminal stenting remains a safe and effective approach in selected patients with critical airway stenosis. Complications, however, do exist and should be realized by the operator, the patients, and their families.

    Notizen: Abstract We prospectively studied thoracoscopic suturing of apical bullae in the management of primary spontaneous pneumothorax. From June 1993 to July 1994, we performed 29 such procedures in 27 patients. (All males ranging in age from 15 to 40.) Bullae less than 2 cm in diameter were imbricated (18), while larger bullae were resected and repaired with 3/0 polypropylene suture (11). Postoperative morbidity was minimal. Averaged postoperative parenteral narcotic (Pethidine) requirement was 88 mg, chest drainage was 1.7 (range 1–4) days, and hospital stay was 2.5 (range 1–7) days. There was no recurrence after a mean follow-up of 10 months. In comparison, 32 patients prior to this study period underwent staple resection of apical bulla. Demographic data in the two groups were similar. Averaged Pethidine requirement in the “staple” group was 98 mg, chest drainage was 1.8 (range 1–5) days, and hospital stay was 2.6 (range 1–7) days. There was no statistical difference in the two groups with respect to pain medication, chest drainage, or hospital stay. The technique of thoracoscopic suturing can be easily acquired. In view of the high cost of staple-cutters, endoscopic suturing should be considered as a viable alternative to staple resection of apical bullae in the treatment of primary spontaneous pneumothorax.

    Notizen: Abstract. A 19-year-old male who presented with cough and fever was found to have an 8-cm cyst in his left lung. Video-assisted thoracoscopic left lower lobectomy was performed. The cyst had to be decompressed by needle aspiration prior to retrieval through a 5-cm minithoracotomy. The patient was discharged on postoperative day 4 in good condition. The technical aspects form the basis of this report.

    Notizen: Abstract A 3-month-old Chinese girl with type I cystic adenomatoid malformation involving both lobes of her left lung was successfully operated upon using the video-assisted thoracoscopic surgical (VATS) approach. The conventional endoscopic stapling device was used for resection without complications.

    Notizen: Abstract We reviewed our experience on video-assisted thoracoscopic surgery (VATS) from our first 100 cases of primary spontaneous pneumothorax (PSP) performed at our institution from September 1992 to January 1994. Apical bullae were identified in 87% of cases. Mechanical pleurodesis with Marlex mesh was performed on all patients. Excision with endoscopic staple cutter was performed in 69 cases; an endoloop was used in five cases; ablation with an argon beam coagulator (ABC) was done in six cases; excision with endoscopic suturing occurred in seven cases; and mechanical pleurodesis alone was used in 13 cases. The overall median postoperative chest tube duration was 2 days (range 1–25 days) and hospital stay 4 days (range 1–30 days). Complications occurred in 8 cases (8%): 1 wound infection; 1 chest wall bleeding; and 6 persistent air leaks which lasted for more than 10 days (one of which eventually required an axillary thoracotomy for control). Procedure failure with recurrence occurred in three cases (3%) at a mean follow-up of 17 months (range 8–24 months). The ABC group alone was responsible for one recurrence and two persistent leaks. We conclude that with the VATS approach in the treatment of PSP, staple resection of apical bullae is quick and most reliable but costly. Endoloop and hand suturing are applicable to selected patients with small and localized bullae and should be further studied, while our limited experience does not favor ABC as the primary treatment modality.

    Beschreibung / Inhaltsverzeichnis: 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.
    Notizen: 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.
