Gastroschisis: A sixteen-year review.

PURPOSE

The aim of this study was to examine the incidence of gastroschisis in Saskatchewan over a 16-year period and identify risk factors associated with mortality.

METHODS

Information was obtained by retrospective review of all infant charts at the only 2 provincial neonatal intensive care centers from January 1985 through December 2000. Factors recorded were gestational age, birth weight, gender, Apgar score, time to operation, method of closure, time to attain full feedings, presence of sepsis, and length of hospital stay. Live birth data for the province was obtained, and the incidence per 10,000 live births for 3 time intervals was calculated. Analysis was performed with mortality as the dependent variable.

RESULTS

Seventy-one infants were identified. Overall survival rate was 93% (66 of 71). During the 3 time intervals examined, the incidence of gastroschisis per 10,000 live births increased from 1.85 in 1985 to 1990 to 3.66 in 1991 to 1995 to 4.06 in 1996 to 2000. The analysis found that intestinal atresia P =.009, OR = 18.3 (95%CI: 2.457-136) and intestinal necrosis P =.050, OR = 10.33 (95%CI: 1.32-80.68) were significantly associated with mortality.

CONCLUSIONS

The incidence of gastroschisis is increasing. Intestinal atresia and the development of intestinal necrosis were associated with poor outcome. Patients who had these complications all had short bowel, and full feedings could not be established. They required continuation of total parenteral nutrition and experienced episodes of sepsis.
