BACKGROUND: This study assesses the clinical effectiveness and technical expertise associated with laparoscopic pyloromyotomy (LP) carried out using conventional instruments for the treatment of congenital hypertrophic pyloric stenosis (CHPS) in infants.
METHODS: We carried out a retrospective analysis of 24 patients who were diagnosed with CHPS at the Department of Pediatric Surgery, Mianyang Central Hospital, from March 2022 to December 2025. The cohort consisted of 19 boys and 5 girls, having a median age of 41 days (range: 13-123 days) and a mean weight of 3.83 ± 0.75 kg (range: 2.1-5.0 kg). All patients presented non-bilious vomiting as the primary symptom. Every patient underwent laparoscopic pyloromyotomy using conventional laparoscopic instruments.
RESULTS: Surgical procedures were successfully accomplished in all 24 cases, without the need for conversion to open surgery. The median operative time was 30 min (range: 13-60 min). All patients resumed oral feeding on the first postoperative day. Three patients (12.5%) suffered from mild and transient vomiting, which lasted for 2 days, 3 days, and 1 week respectively. These symptoms resolved spontaneously after conservative management, specifically by reducing the feeding volume and increasing the feeding frequency, without the necessity of further intervention. No other complications were detected. The postoperative hospital stay length ranged from 1 to 5 days. The follow - up durations varied from 2 months to 3 years and 11 months, during which all patients showed symptom resolution and normal growth patterns.
CONCLUSION: Laparoscopic pyloromyotomy performed with conventional instruments is a safe and effective intervention for infants suffering from hypertrophic pyloric stenosis. This technique presents the advantages of minimal invasiveness, procedural simplicity, and low complication rates, thus standing as a viable option for extensive clinical application.
