Treating idiopathic hypertrophic pyloric stenosis with sequential therapy: A clinical study

Area of Science:

• Pediatric Surgery
• Gastroenterology

Background:

• Idiopathic hypertrophic pyloric stenosis (IHPS) is a common cause of non-bilious vomiting in infants.
• Surgical pyloromyotomy is the standard treatment for IHPS.

Purpose of the Study:

• To evaluate the efficacy and safety of sequential therapy (ST) with atropine for IHPS.
• To compare atropine ST with laparoscopic surgery in terms of clinical outcomes and cost-effectiveness.

Main Methods:

• A comparative study involving 49 infants with IHPS from January 2010 to June 2013.
• Infants were randomized into two groups: atropine ST (n=26) and laparoscopic surgery (n=23).
• Outcomes assessed included vomiting remission, complications, hospital stay, medical expenditure, body weight, and pyloric muscle thickness at 6 months.

Main Results:

• The vomiting remission rate was 88.5% in the ST group versus 100% in the surgery group.
• No significant differences were observed in complication rates, body weight, or pyloric muscle thickness between groups.
• The ST group experienced a longer hospital stay but significantly lower medical expenditure.

Conclusions:

• Atropine ST is a safe, effective, and cost-effective alternative for IHPS treatment compared to surgery.
• While surgery offers higher efficacy in vomiting remission, ST presents a viable, less expensive option with comparable safety profiles.
