Mortality and postoperative care after emergency laparotomy.

Area of Science:

• Surgical Outcomes
• Critical Care Medicine
• Geriatric Surgery

Background:

• Emergency laparotomy is a high-risk procedure with limited outcome and postoperative care data.
• Understanding mortality and the impact of postoperative care is crucial for this patient population.

Purpose of the Study:

• To observe mortality rates in a mixed general surgical population undergoing emergency laparotomy.
• To explore the influence of different postoperative care pathways on patient mortality.

Main Methods:

• A prospective observational study involving 124 patients undergoing emergency laparotomy.
• Calculation of predicted death rate (PDR) using P-POSSUM score and standardized mortality ratio (SMR).
• Comparison of mortality across different postoperative care pathways: PACU-ward, ICU-HDU-ward, and PACU-HDU-ward.

Main Results:

• Overall mortality was 19.4% (21 patients died within 30 days).
• Patients over 80 years had a significantly higher mortality rate (38%).
• The PACU-HDU-ward pathway showed 0% mortality, contrasting with higher rates in PACU-ward (13.6%) and ICU-HDU-ward (40.0%) pathways.

Conclusions:

• Emergency laparotomy is associated with high mortality, particularly in elderly patients.
• The standardized mortality ratio (SMR) suggests that the PACU-ward pathway may require optimization compared to ICU-HDU-ward pathways.
• Postoperative care pathway selection significantly influences survival outcomes after emergency laparotomy.
