Summary
Neuroimmune interactions in the gut influence gastrointestinal disorders. This review explores how the enteric nervous system and gut immunity contribute to postoperative ileus and postinfectious irritable bowel syndrome (PI-IBS).
Area of Science:
- Gastroenterology
- Neuroimmunology
- Gastrointestinal Physiology
Background:
- The enteric nervous system (ENS) and gut immune system are crucial for gastrointestinal function.
- Close interactions between the ENS and gut immunity are increasingly recognized.
- Dysregulation of these interactions contributes to functional gastrointestinal disorders.
Purpose of the Study:
- To review the pathophysiology of postoperative ileus and postinfectious irritable bowel syndrome (PI-IBS).
- To highlight the role of neuroimmune interactions in these common gastrointestinal disorders.
Main Methods:
- Literature review focusing on neuroimmune mechanisms in functional gastrointestinal disorders.
- Analysis of studies investigating postoperative ileus and PI-IBS pathogenesis.
Main Results:
- Postoperative ileus involves local inflammation and altered neuronal pathways impairing gut motility.
- PI-IBS is characterized by persistent low-grade inflammation and altered immune function, leading to visceral hypersensitivity and motor disturbances.
- Neuroimmune dysregulation contributes to symptoms like abdominal pain, altered bowel habits, and bloating.
Conclusions:
- Neuroimmune interactions are central to the pathophysiology of both postoperative ileus and PI-IBS.
- Understanding these mechanisms offers potential therapeutic targets for functional gastrointestinal disorders.

01:17Irritable Bowel Syndrome I: Introduction
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:

01:23Irritable Bowel Syndrome
DefinitionIrritable bowel syndrome (IBS) is a functional gastrointestinal disorder characterized by recurrent combinations of abdominal pain, bloating, diarrhea, or constipation.Pathophysiology of irritable bowel syndromeIts pathophysiology is multifactorial, involving disturbances in motility, sensory processing, microbial balance, barrier integrity, and gut–brain communication. These mechanisms interact to produce symptoms that vary across IBS subtypes.Altered Motility PatternsDisordered...
01:22Gut-Brain Axis
The gut–brain axis is a bidirectional communication system that connects the gastrointestinal tract and the brain. This interaction is mediated through multiple pathways, including the vagus nerve, hormonal signals, immune responses, and chemical messengers produced by gut microbes.Microbial Contributions to Brain FunctionGut microbiota contributes significantly to brain function by producing neuroactive compounds. These include neuroactive compounds that influence neurotransmitters such as...
01:17Chronic Bowel Disorders: Introduction
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

01:18Dysbiosis of the Gut Microbiota
The human gut microbiome includes a diverse array of microbial species, including beneficial commensals and opportunistic pathogens, which interact to support host health. These microbes contribute to essential functions such as nutrient metabolism, immune system modulation, and maintenance of intestinal barrier integrity. However, disruptions to this equilibrium—referred to as dysbiosis—can have widespread physiological consequences.Dysbiosis is often characterized by reduced microbial...
01:20Inflammatory Bowel Disease II: Ulcerative Colitis
Ulcerative colitis is a chronic inflammatory disorder of the colon characterized by continuous mucosal inflammation that typically begins in the rectum and extends proximally in a uniform pattern. Its pathogenesis involves a complex interplay of genetic predisposition, immune dysregulation, and environmental influences. These factors converge to impair the colon’s epithelial defenses and promote an exaggerated inflammatory response against luminal contents.Breakdown of the Mucosal BarrierA...
