Crosstalk in the Abdomen: The Interface of the Omentum and the Microbiome in Sepsis.

Previously considered inert, the greater omentum is now thought to play a central role in intra-peritoneal immune defense. The intestinal microbiome has recently become a target for potential therapeutic interventions. A narrative review of the immune functions of the omentum was generated using the Scale for the Assessment of Narrative Review Articles (SANRA) guideline. Articles were selected from domains including surgical history, immunology, microbiology, and abdominal sepsis. Evidence suggests the intestinal microbiome may be responsible for some maladaptive physiologic responses in disease states, particularly intra-peritoneal sepsis. Elaborate crosstalk exists between the gut microbiome and the omentum, given its innate and adaptive immune capabilities. We summarize current knowledge, provide examples of how normal and abnormal microbiomes interface with the omentum, and illustrate their impact on surgical disease and its management.
