[Randomized trial on the value of diagnostic laparoscopy before appendectomy].

Two groups of 30 women with clinical signs of appendicitis were randomized to immediate appendicectomy or diagnostic laparoscopy. In the latter group, appendicectomy was performed if a diagnosis of acute appendicitis was established or if the appendix could not be visualized. Eleven patients who underwent immediate operation had unnecessary appendicectomy, compared with two who underwent laparoscopy. This difference of 30% (95% confidence interval 11-49%) was significant (p = 0.01). There was no significant difference in postoperative morbidity rate in the two groups. Diagnostic laparoscopy is a useful preliminary investigation in women with clinical signs of acute appendicitis.

Randomized study of the value of laparoscopy before appendicectomy.

Two groups of 30 women with clinical signs of appendicitis were randomized to immediate appendicectomy or diagnostic laparoscopy. In the latter group, appendicectomy was performed if a diagnosis of acute appendicitis was established or if the appendix could not be visualized. Eleven patients undergoing immediate operation had unnecessary appendicectomy, compared with two having laparoscopy. This difference of 30 per cent (95 per cent confidence interval 11-49 per cent) was significant (P = 0.01). There was no significant difference in postoperative morbidity rate in the two groups. Diagnostic laparoscopy is a useful preliminary investigation in women with clinical signs of acute appendicitis.

[Surgical treatment of lung cancer in Denmark in 1982-1986. Special attention to the surgical procedure and mortality].

UNLABELLED: The operative activity and hospital mortality for lung cancer in Denmark, were investigated for the five year period from 1982 to 1986. Of the 2,898 operations performed 38.3% were pneumonectomies, 34.2% lobectomies, 6.0% lesser resections (segmental or wedge) and 21.5% were exploratory thoracotomies. The total hospital mortality was 7.2% (208 patients). Following pneumonectomy, the hospital mortality was 11.2%, after lobectomy 3.5% (p less than 0.001). Lesser resections carried a 2.3% mortality, not statistically different from lobectomy. Exploratory thoracotomy was connected with a mortality of 7.2%. In patients under the age of 60 years the mortality was 4.7% and in patients at the age of 60 to 69 years 7.9% (p less than 0.01). Patients over 70 years carried a mortality of 9.7%, not statistically different from patients from 60 to 69 years. The hospital mortality was significantly higher in the nonspecialized departments. IN CONCLUSION: Lung cancer is still increasing. Compared to the past the resectability rate is decreasing and hospital mortality is almost unchanged. To improve the results of efforts to increase the proportion of curable patients have to go hand in hand with efforts to reduce the numbers of exploratory thoracotomies and pneumonectomies as well as the number of operative and postoperative complications. Further centralization must be considered, in order to obtain better selectionscriteries and optimal treatment modalities per- and postoperatively.

[Reoperation for angina pectoris].

During the 16-year period from 1974 to 1989, coronary bypass operations were carried out on 938 patients. During the same period, 48 patients (5.1%) were submitted to reoperation on account of recurrent angina pectoris. Patients with early recurrence had more frequently graft-occlusion than patients with late recurrence in whom the main cause was progression of the arteriosclerotic cardiac condition. The actual rethoractomy was carried out without serious complications. The perioperative frequency of complications and the mortality correspond to the frequencies at the first operation. Follow-up control of these patients was undertaken after an average of 34 months (8-100) after reoperation. The results after reoperation as regards freedom from symptoms are not quite as good as the results after the primary operation but approximately 2/3 of the patients will benefit from reoperation.
