Overview
Abdominal distention represents a prevalent clinical manifestation characterized by an unclear etiology and pathogenesis. This symptomatology is frequently observed in various conditions, including small intestinal bacterial overgrowth (SIBO) and abnormal orocecal transit time (OCTT). The utilization of the breath test as a non-invasive diagnostic approach has become widespread in recent years for identifying SIBO and abnormalities in OCTT. In this study, the prevalence of SIBO and OCTT irregularities in individuals presenting with abdominal distention was ascertained through the implementation of the breath test. Furthermore, the correlation between abdominal distention and SIBO/OCTT was analysed to enhance the elucidation of the underlying etiology of abdominal distention. These findings aim to offer valuable insights for refining clinical comprehension and strategies related to the diagnosis and treatment of abdominal distention.
Detailed description
Abdominal distention represents a prevalent clinical manifestation characterized by an unclear etiology and pathogenesis. And the prevalence of abdominal distension is high in the population. This symptomatology is frequently observed in various conditions, including small intestinal bacterial overgrowth (SIBO) and abnormal orocecal transit time (OCTT). The utilization of the breath test as a non-invasive diagnostic approach has become widespread in recent years for identifying SIBO and abnormalities in OCTT. In this study, the prevalence of SIBO and OCTT irregularities in individuals presenting with abdominal distention was ascertained through the implementation of the breath test. Furthermore, the correlation between the clinical features such as severity, location, and frequency of abdominal distension and SIBO/OCTT was analysed to enhance the elucidation of the underlying etiology of abdominal distention. These findings aim to offer valuable insights for refining clinical comprehension and strategies related to the diagnosis and treatment of abdominal distention.
Interventions
- Diagnostic test Breath test
The concentration of methane and hydrogen in the exhaled gas of patients with Abdominal distention is measured by a breath test to determine the presence of SIBO and abnormal OCTT.
Primary outcome measures
- Positive rate of SIBO in patients with abdominal distension [Time frame: 2024-03-01 to 2025-08-01]
Secondary outcome measures (3)
- Positive rate of abnormal OCTT in patients with abdominal distension [Time frame: 2024-03-01 to 2025-08-01]
- Correlation between clinical features of patients with abdominal distension and SIBO [Time frame: 2024-03-01 to 2025-08-01]
- Correlation between clinical features of patients with abdominal distension and OCTT [Time frame: 2024-03-01 to 2025-08-01]
