Delay in operative treatment among patients with small bowel obstruction.

BACKGROUND AND AIMS

Delay in operative treatment for small bowel obstruction (SBO) has been shown to affect outcome adversely. The objective of this study was to detect time trends in treatment delay for patients with SBO during the study period 1961 to 1995 and to investigate factors influencing and factors affected by delay.

MATERIALS AND METHODS

The records of 815 patients with 921 operations for SBO from 1961-1995 were studied. Patients with large bowel obstruction, paralytic ileus and SBO caused by abdominal cancer or intussusception were excluded. Data were analysed with descriptive statistics and multiple linear regression analyses.

RESULTS

Old age and female sex were associated with increased treatment delay. Delay in hospital increased from 5 hours (median) in the 1960'ies to 16 hours (median) in the 1990'ies. Treatment delay correlated significantly with postoperative morbidity and hospital stay. Mortality increased after prolonged treatment delay in SBO caused by hernias whereas no significant increase in mortality was observed among adhesive obstructions.

CONCLUSIONS

Hospital delay increased throughout the study period. Old patients and women had a longer median treatment delay than did young ones and men. Treatment delay led to an increase in postoperative morbidity and hospital stay after surgery for SBO.
