Question
Based on the doctor’s advice, the child underwent a lower gastrointestinal contrast study and enema examination. The results showed an abnormal curved and long sigmoid colon with poor defecation function. How should this situation be handled?
Answer
If the sigmoid colon is congenitally elongated, prolapsed, and forms a sharp angle with the rectum, it may lead to progressive hyperperistalsis of the sigmoid colon, which could cause fatigue damage in the long run. If the sigmoid colon pouch disappears, it can be preliminarily judged that its peristaltic function has been lost. Patients can often perform chest-knee exercises to enhance mesenteric tension, reduce angles, and help defecation. For those with severe symptoms, partial resection surgery can be considered. Abnormal curvature of the sigmoid colon can be confirmed through X-ray defecation contrast imaging and barium enema. The degree of curvature varies, and the resistance to defecation also increases accordingly. Since forceful defecation creates a downward vertical abdominal pressure, and the coiled intestines…
