What is small bowel volvulus commonly associated with?
Common causes of small bowel volvulus include abnormal intestinal anatomical structure, intestinal motility disorders, improper dietary stimulation, abdominal external force, and excessive intestinal load. It is often triggered by a combination of multiple factors and is considered a surgical emergency. If sudden severe abdominal pain, vomiting, or cessation of defecation and flatus occur, immediate medical attention is recommended.
1. Abnormal intestinal anatomical structure: Conditions such as excessively long mesentery or abnormal attachment points, and congenital malrotation of the intestine, increase intestinal mobility and predispose the bowel to twisting during changes in body position. This serves as a key anatomical basis for volvulus.
2. Intestinal motility disorders: Factors like cold exposure to the abdomen, emotional stress, or hormonal fluctuations can disrupt normal peristaltic rhythm, causing segments of the intestine to contract too quickly or spasm, thereby promoting twisting.

3. Improper dietary stimulation: Rapid consumption of large meals or excessive intake of gas-producing foods leads to swift intestinal distension and bloating. The increased weight and tension in the bowel may result in uneven forces during peristalsis, triggering volvulus.
4. Abdominal external force: Trauma such as abdominal impact or compression, or post-surgical adhesions that pull on the intestines, can alter the normal position and movement of the bowel, increasing the risk of twisting.
5. Excessive intestinal load: Accumulation of fecal matter, parasitic infections, or space-occupying lesions such as tumors can increase local intestinal weight. During peristalsis, this imbalance in weight distribution may lead to torsion.
To reduce risks, maintain regular eating habits, avoid overeating and excessive intake of gas-producing foods, keep the abdomen warm to prevent cold exposure, and refrain from vigorous exercise immediately after meals to minimize intestinal irritation and burden.
