SUMMARY BackgroundReliable epidemiological data for portal vein thrombosis are lacking.

Budd-Chiari syndrome is a rare disorder; the mean age-standardised incidence and prevalence rates in Sweden in 1990-2001 were calculated to be 0.8 per million per year and 1.4 per million inhabitants respectively. The presence of a myeloproliferative disorder was a common aetiological factor in our cohort and about half of the patients had a multifactorial aetiology. The transplantation-free survival was poor.

Laparoscopic 360 degrees fundoplication is as effective in treating reflux disease as open fundoplication. Six months postoperatively, no significant differences were seen in symptomatic or objective outcome. Long-term evaluation is needed.
