Study information
Scientific title
Acronym
RELAP trial
Study hypothesis
Relaparotomy on demand strategy in patients with secondary peritonitis reduces the risk of 180-day poor outcome (death or readmission/surgical intervention for morbidity in survivors) compared to a strategy with planned relaparotomy.
Ethics approval
Approved by the Medical Ethics Committee, Academic Medical Center, Amsterdam, The Netherlands and by the Dutch Central Committee on Research Involving Human Subjects (Dutch initials: CCMO).

Primary outcome measures
Poor outcome defined as death (all-cause mortality) or, in survivors, readmission or surgical intervention for disease-related morbidity (i.e., morbidity related to abdominal sepsis and its treatment) during a 180-day period after index laparotomy.
Secondary outcome measures
1. Duration of mechanical ventilation, Intensive Care Unit (ICU) and hospital stay, days outside the hospital in one year after index surgery, long-term morbidity (one year), quality of life, and Quality-Adjusted Life-Years (QALYs).
2. Medical and indirect costs comparing absolute volumes of resource utilization.
