Endoscopic vs open saphenous vein harvest for coronary artery bypass grafting: a prospective randomized trial.

OBJECTIVE: Endoscopic saphenous vein harvesting (EVH) for coronary artery bypass grafting (CABG) has been developed to reduce leg wound morbidity and improve patient satisfaction. Choosing between EVH of a short vein segment from the thigh and open venous harvesting (OVH) of a short segment from the calf represents a clinical dilemma as EVH is easiest to perform from the thigh and OVH is easiest to perform from the calf. The purpose of this study was to investigate whether leg wound morbidity was reduced after EVH of a short vein segment from the thigh compared with OVH from the calf. Secondly we investigated whether EVH would reduce length of hospital stay and improve cosmetic results. METHODS: From April 2004 to June 2007, 132 patients undergoing elective isolated CABG were randomized to have a short segment of saphenous vein harvested either by the EVH or OVH technique. Clinical follow-up was scheduled at day 5 and at 1 month. Primary end-points included wound morbidity. Secondary end-points included harvest time, length of hospital stay, cosmetic results and need for additional wound care after discharge. RESULTS: The groups were preoperative similar. Three patients in the OVH group were excluded from the study as it became apparent that it was necessary to extend the incision beyond the knee. Harvest time was longer for the EVH group, but these patients suffered from significantly fewer cases of infectious and non-infective wound complications, with a substantial reduction in the need for post-discharge leg wound care. The purulent infection rates in the EVH and OVH groups were 0% and 11%, respectively. The overall leg wound morbidity rates regarding cellulitis, purulent infection, dehiscence and skin necrosis were 3% and 27% in the EVH and OVH groups, respectively (p<0.001). The length of hospital stay was similar. The conversion rate from EVH to OVH was 14%. The EVH group experienced less pain and better cosmetic results. CONCLUSIONS: EVH of a short vein segment from the thigh results in less wound morbidity and better cosmetic results compared with OVH of a short vein segment from the calf.

A Novel Device for Accurate Chest Tube Insertion: A Randomized Controlled Trial.

BACKGROUND: Optimal positioning of a large-bore chest tube is in the part of the pleural cavity that needs drainage. It is recommended that the chest tube be positioned apically in pneumothorax and basally for fluids. However, targeted chest tube positioning to a specific part of the pleural cavity can be a challenge. METHODS: A new medical device, the KatGuide, was developed for accurate guiding of a chest tube (28F) to an intended part of the pleural cavity. The primary end point of this randomized, controlled trial was optimal position of the chest tube. The optimal position in pneumothorax was apical (above the aortic arch), and the optimal position in hemothorax, hydrothorax, chylothorax, or empyema was basal (2 cm above the diaphragm or lower). The patients were randomized for the KatGuide method or the conventional forceps method, and rates of optimal position were compared. RESULTS: A total of 109 patients were enrolled (KatGuide: n = 49; conventional: n = 60). Chest tubes were optimally position in 41 (84%) in the KatGuide group vs 32 (53%) in the conventional group (p = 0.001). Experienced operators (>50 previous chest tube insertions) inserted 39 of the chest tubes, of which, 15 of 17 (88%) were optimally positioned in the KatGuide group vs 11 of 22 (50%) in the conventional group (p = 0.02). Two chest tubes (4%) were misplaced in the KatGuide group vs 11 (18%) in the conventional group (p = 0.04). No adverse device effects were observed. CONCLUSIONS: The KatGuide significantly improves the probability of optimal chest tube position and reduces the risk of misplacement compared with the conventional method.

[Esophageal achalasia]. / Stemples achaliazija.

UNLABELLED: The purpose of this study was to analyze results of pneumatic dilatation due to esophageal achalasia at the Clinic of General Thoracic Surgery of Vilnius University. MATERIAL AND METHODS: During 25-year period (1973-1998) we have treated 133 achalasia patients. On 125 patients pneumatic dilatation was performed. One hundred five (84%) patients recovered fully. Single course of pneumatic dilatations was sufficient. Recurrence rate was 16% - 3 courses of pneumatic dilatations were performed on 2 (1.6%), 2 - on 18 (14.4%) patients. Complications. The major complication of pneumatic dilatation is esophageal perforation. Most series report its incidence at about 2%. In our study 2 cases (1.6%) of esophageal perforation occurred. Both patients were operated immediately. One (0.8%) died because of purulent complications. CONCLUSION: Pneumatic dilatation is safe and effective method of treatment. In our opinion, it would be the best initial approach. If it failed, then myotomy would be treatment of choice.

[A gastropleural fistula can be treated thoracoscopically].

Gastropleural fistula (GPF) is although uncommon a severe and sometimes fatal complication after prior thoracic surgery, trauma or malignancy. Standard therapy has often included major surgery such as laparotomia with gastrectomi. In this case report we present a patient with GPF who underwent thoracoscopia for closure of the fistula. To our knowledge this is the first report of its kind in the Danish and English literature. Thoracoscopic treatment of GPF may be associated with less morbidity and mortality, and should be considered as the initial procedure of choice.

Short and long-term effects of supervised versus unsupervised exercise training on health-related quality of life and functional outcomes following lung cancer surgery - a randomized controlled trial.

OBJECTIVE: Surgical resection enhances long-term survival after lung cancer, but survivors face functional deficits and report on poor quality of life long time after surgery. This study evaluated short and long-term effects of supervised group exercise training on health-related quality of life and physical performance in patients, who were radically operated for lung cancer. METHODS: A randomized, assessor-blinded, controlled trial was performed on 78 patients undergoing lung cancer surgery. The intervention group (IG, n=41) participated in supervised out-patient exercise training sessions, one hour once a week for ten weeks. The sessions were based on aerobic exercises with target intensity of 60-80% of work capacity, resistance training and dyspnoea management. The control group (CG, n=37) received one individual instruction in exercise training. Measurements consisted of: health-related quality of life (SF36), six minute walk test (6MWT) and lung function (spirometry), assessed three weeks after surgery and after four and twelve months. RESULTS: Both groups were comparable at baseline on demographic characteristic and outcome values. We found a statistically significant effect after four months in the bodily pain domain of SF36, with an estimated mean difference (EMD) of 15.3 (95% CI:4 to 26.6, p=0.01) and a trend in favour of the intervention for role physical functioning (EMD 12.04, 95% CI: -1 to 25.1, p=0.07) and physical component summary (EMD 3.76, 95% CI:-0.1 to 7.6, p=0.06). At 12 months, the tendency was reversed, with the CG presenting overall slightly better measures. We found no effect of the intervention on 6MWT or lung volumes at any time-point. CONCLUSION: Supervised compared to unsupervised exercise training resulted in no improvement in health-related quality of life, except for the bodily pain domain, four months after lung cancer surgery. No effects of the intervention were found for any outcome after one year.
