AI Article Synopsis
- Radical surgery is the best treatment for Hirschsprung's disease, but many kids still face issues like constipation and abdominal distension post-op.
- This study analyzed the effects of botulinum toxin injections and internal sphincter myectomy on these symptoms in children after surgery from July 2019 to July 2021.
- Results showed significant improvements in symptoms after botulinum injections and myectomy, suggesting these treatments effectively address postoperative intestinal dysfunction in affected children.
Article Abstract
Purpose: Radical surgery is the most effective treatment for Hirschsprung's disease. However, some children still have symptoms of intestinal dysfunction such as constipation, abdominal distension, and recurrent enterocolitis after operation. The purpose of this study was to evaluate treatment outcomes of postoperative intestinal dysfunction in children with Hirschsprung's disease by using the principle of "anorectal balance".
Methods: The clinical data of postoperative intestinal dysfunction in children with Hirschsprung's disease in the single treatment group from July 2019 to July 2021 were retrospectively analyzed. All the enrolled children underwent botulinum toxin injection (2.5 U/kg); 3 to 6 months later, the injection was performed again; the children who had received more than two botulinum toxin injections underwent the internal sphincter myectomy. Anorectal manometry was performed routinely after operation, and abdominal distension and defecation were recorded.
Results: A total of thirty children with postoperative intestinal dysfunction underwent radical surgery for Hirschsprung's disease were included in this study. Symptoms of constipation, abdominal distension and enterocolitis were improved after botulinum toxin injections in most children compared to before surgery ( < 0.01). After re-injection of botulinum toxin in twelve children, the frequency of defecation increased, the anal resting pressure decreased, and the clinical symptoms were relieved again ( < 0.05). Eleven children underwent internal sphincter myectomy, and the symptoms of constipation, abdominal distension and enterocolitis were significantly improved after the operation ( < 0.01).
Conclusion: Botulinum toxin injection and internal sphincter myectomy based on the principle of "anorectal balance" can effectively reduce the resting pressure of the anus and relieve intestinal dysfunction, and have satisfactory clinical effect.

The intestinal barrier function is a critical defense mechanism in the human body, serving as both the primary target and initiating organ in cases of sepsis. Preserving the integrity of this barrier is essential for preventing complications and diseases, including sepsis and mortality. Despite this importance, the impact of resveratrol on intestinal barrier function remains unclear.

With the rising prevalence of type 2 diabetes mellitus (T2DM) and obesity, several previously under-recognised complications associated with T2DM are becoming more evident. The most common of these emerging complications are metabolic dysfunction-associated steatotic liver disease (MASLD), cancer, dementia, sarcopenia, and frailty, as well as other conditions involving the lung, heart, and intestinal tract. Likely causative factors are chronic inflammation and insulin resistance, whereas blood glucose levels appear to play a lesser role.

Tirzepatide is a dual agonist of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors and is a promising therapeutic option for type 2 diabetes mellitus (T2DM). Nevertheless, its effect and underlying mechanism on hepatic steatosis remain ambiguous. Herein, we explored the impact of tirzepatide on improving hepatic steatosis in diabetic mice, with a particular focus on the gut microbiota and bile acids (BAs) using animal models.

Gut dysbiosis serves as an underlying risk factor for the development of hypertension. The resolution of this dysbiosis has emerged as a promising strategy in improving hypertension. Food-derived bioactive protein peptides have become increasingly more attractive in ameliorating hypertension, primarily due to their anti-inflammatory and anti-oxidant activities.

Background: Our previous studies reported that D-galactose (D-gal) administration for four to eight weeks caused metabolic disturbance, brain mitochondrial dysfunction, and brain aging, leading to cognitive dysfunction in similar with natural aging condition. Spermidine is a polyamine that can be found naturally. Spermidine has been showed the beneficial effects on various models, such as attenuating metabolic/gut impairments in obesity, and ameliorating memory loss in aged model.
