RESUMO
BACKGROUND: Adhesive bowel obstruction is a serious complication to abdominal surgery. It is unknown whether incidence and mortality rates have changed as new surgical procedures were introduced. METHODS: In a nationwide cohort of Danish women from 1984 to 2013, incidence of adhesive bowel obstruction and 30 days mortality were presented as standardized rates. Impact of treatment was analyzed by Cox regression and recurrent disease characterized by Kaplan Meyer estimates. RESULTS: Incidence of adhesive bowel obstruction increased 50% among women with no prior abdominal surgery. These women had 3-5 times lower incidence than those with a surgical record. 30-day mortality rate was 13%, highest in patients treated non-operatively. The mortality declined in recent years. Recurrent disease had lower mortality rates compared to the first episode. CONCLUSIONS: The incidence of adhesive bowel obstruction increased during the last 30 years, mortality after the first episode is high, while recurrent disease shows declining mortality rates.
