One-Year Outcomes Following Emergency Laparotomy: A Systematic Review.

BACKGROUND

Emergency laparotomies (EL) are associated with significant morbidity and mortality. To date, 30-day mortality has been predominately reported, and been the focus of various national emergency laparotomy audits. Only a few studies have reported on the long-term mortality associated with EL. The aim of this study was to review the one-year mortality following EL.

METHOD

A systematic review was conducted using PRISMA guidelines to identify studies published in the last 10 years reporting on long-term mortality associated with EL. The data abstracted included: patient demographics, pathology or type of operation performed for EL, post-operative mortality at 7-day, 30-day, 90-day, 1-year, beyond 1-year and inpatient, functional outcomes and risk factors associated with mortality. A quality assessment of included studies was performed.

RESULTS

Fifteen studies reporting long-term outcomes associated with EL were identified, including the results of 48,023 patients. The indications and/or pathologies for ELs varied. The 30-day mortality after EL ranged from 5.3% to 21.8%, and the one-year mortality ranged from 15.1 to 47%. The mortality in the six studies focusing on elderly patients ranged from 30 to 47%.

CONCLUSION

The long-term mortality rate associated with EL is substantial. Further study is required to understand the 1-year mortality described in the studies and translate these findings for meaningful application into the clinical care of these patients.
