- Background: Laparoscopic herniorrhaphy has emerged as a recognized operative method for inguinal hernia repair. This study compared the short-term results of two tension-free methods of repair: totally extraperitoneal (TEP) laparoscopic patch repair and the open Lichtenstein mesh technique. Methods: A total of 1513 men from 11 hospitals who presented with a primary unilateral inguinal hernia were randomized to one of the two methods. Operating time, short-term complications, reoperations, postoperative pain, consumption of analgesics, sick leave and time to resumption of normal physical activities were recorded. Results: Some 1371 of the 1513 men underwent surgery, 665 in the TEP group and 706 in the Lichtenstein group. The median duration of operation was 55 min for both procedures and 91.0 per cent of die patients in both groups were discharged on the day of operation. Patients in the TEP group experienced less postoperative pain (P < 0.001), consumed fewer analgesics (P < 0.001), had a shorter period of sick leave (7 versus 12 days; P < 0.001) and a shorter time to resumption of normal physical activity (20 versus 31 days; P < 0.001). Conclusion: The TEP technique took no longer to perform, and was associated with less postoperative pain, a shorter period of sick leave and a faster recovery, compared with open Lichtenstein hernia repair.

- This paper explores the relation between ownership structure, board composition and firm performance among Swedish listed firms. The descriptive statistics show that Swedish board of directors have become more diversified in terms of gender. The analysis show that board size has a significant negative effect on investment performance. Gender diversity has a small but negative effect on investment performance, and the same holds for CEO being on the board. When incorporating all the explanatory variables into the same equation the negative effect of larger boards dilutes the effect of gender diversity and having the CEO on the board.

Ownership Structure, Board Composition and Investments Performance
- 2009

Konferensbidrag (refereegranskat)abstract
- In this paper the relation between ownership structure, board composition and firm performance is explored. A panel of Swedish listed firms is used to investigate how board composition affects firm performance. Board heterogeneity is measured as board size, age and gender diversity. The results show that Swedish board of directors have become more diversified in terms of gender. Also, fewer firms have the CEO on the board which can be interpreted as a sign of increased independency. The regression analysis shows that gender diversity has a small but negative effect on investment performance, and the same holds for CEO being on the board. The analysis also show that board size has a significant negative effect on investment performance. When incorporating all the explanatory variables into one equation however, the negative effect of larger boards dilutes the effect of gender diversity and having the CEO on the board.
