OC-058 MORTALITY OF THE ELDERLY: ANALYSIS OF DATA FROM THE LAPARASTOMA REGISTRY

Abstract

Abstract Aim The therapeutic concept of open abdomen with temporary abdominal wall closure was introduced about 30 years ago. Since that time, various surgical strategies have been tried, continuously developed and established. In May 2015, a laparastoma registry was released in the form of an internet-based online platform. Methods Data from the laparastoma registry were analyzed and evaluated. The focus of the study was on the mortality of patients in the age group 75 years and older who underwent laparastoma treatment. Special attention was paid to the previous diseases, risk factors, MPI. Results 913 patients with open abdomen and subsequent laparastomy treatment were enrolled in the laparastomy registry from 2015 to 2022. 65% of patients were male. 69.6% had secondary diseases. The indications for laparastoma establishment were peritonitis (37.2%, N=340), trauma (9.2%, n=84), abdominal compartment (18.1%, n=165) and others. The overall mortality rate was 28.7%. The mortality rate in the group between 75 and 80 years (n=155) was 36% (OR= 1.445 [CI: 1.002–2.008]; p=0.049). The mortality rate in patients older than 75 years (n=67) was 40.3% (OR 1.680 CI 1.008–2.802; p=0.047). Conclusion In the evaluation, three key questions were raised and analyzed by the study: what is the mortality in the elderly patients under laparastoma treatment, what is the mortality in the patients over 75 years old? What are the leading risk factors in the two groups.
