7. Cholecystectomy : studies on surgical methods, incidence and economy
Sammanfattning : After almost a century without change in the surgical care of gallstone disease since the first cholecystectomy in 1882, a profound change in surgical treatment of gallstones has taken place over the last three decades with the introduction of endoscopic sphincterotomy for treatment of bile duct stones (EST), minilaparotomy cholecystectomy (MC), and laparoscopic cholecystectomy (LC).

8. Preeclampsia and other circulatory diseases during pregnancy : etiological aspects and impact on female offspring
Sammanfattning : The aims of this thesis were to investigate and compare environmental effects on the liability of developing preeclampsia and gestational hypertension; to estimate the relative importance of genetic and environmental effects on the liability of developing preeclampsia and gestational hypertension; to assess the effect of childbearing on the risk of circulatory diseases; and to explore the effect of preeclampsia on the female offspring anthropometry in early adulthood. We used the Swedish Birth Register to compare the effect of maternal diabetes, multiple birth, smoking, place of birth and obesity, on the liability of developing preeclampsia and gestational hypertension among 10,666 primiparous women.
