Sepsis Management in Post-bariatric Surgery Patients Using Extracorporeal Blood Purification Treatment, A Case Series

Abstract

Introduction. Bariatric surgery (BS) is among the most effective 
treatments for severe obesity. However, it is essential to 
acknowledge the risk of serious short-term complications following 
the procedure.
 Case Presentation. We report four cases of Iranian patients 
admitted due to severe short-term complications following sleeve 
gastrectomy (SG), which included peritonitis, acute respiratory 
distress syndrome (ARDS), acute kidney injury (AKI), and sepsis. 
Based on their diagnoses and individual needs, two patients 
underwent exploratory laparotomy. All four cases were successfully 
treated with intravenous antibiotics, intensive supportive care, 
and continuous renal replacement therapy (CRRT) along with 
extracorporeal hemoperfusion.
 Conclusions. SG is one of the most commonly performed metabolic 
procedures worldwide. However, it can lead to severe, life
threatening complications, such as sepsis resulting from peritonitis 
and pneumonia. These cases underscore the importance of early 
recognition and effective treatment strategies for this patient 
population. A strict postoperative follow-up is essential for the 
early detection and management of complications, ultimately 
reducing morbidity and mortality rates.
