Infantile hypertrophic pyloric stenosis in Dar Es Salaam
1Muhimbili Medical Centre, Dar Es Salaam, Tanzania.
Insights
This study reviewed 15 infant cases of hypertrophic pyloric stenosis, finding an incidence of 1 in 5,500 births. The standard Fredet-Ramstedt pyloromyotomy procedure was used with a 6.7% mortality rate.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Public Health
Background:
- Hypertrophic pyloric stenosis (HPS) is a common congenital anomaly affecting infants.
- Accurate incidence data and management outcomes are crucial for understanding disease burden.
Purpose of the Study:
- To review the management and outcomes of infants with HPS at Muhimbili Medical Centre.
- To determine the incidence rate of HPS in the local population.
Main Methods:
- A retrospective review of medical records was conducted over a five-year period.
- Data collected included patient demographics, clinical presentation, surgical procedure, and outcomes.
- The Fredet-Ramstedt pyloromyotomy was the standard surgical intervention.
Main Results:
- Fifteen infants diagnosed with HPS were managed during the review period.
- The male-to-female ratio was 6.5:1, with a majority of cases occurring in African infants.
- The approximate incidence rate was calculated to be 1 in 5,500 births.
- All patients underwent the Fredet-Ramstedt pyloromyotomy, with a mortality rate of 6.7%.
Conclusions:
- Hypertrophic pyloric stenosis is a significant surgical condition in infants in Dar es Salaam.
- The Fredet-Ramstedt pyloromyotomy remains an effective treatment for HPS.
- Further studies are needed to explore potential risk factors and long-term outcomes.
Abstract:
A five-year review revealed that 15 infants with hypertrophic pyloric stenosis were managed in Muhimbili Medical Centre. All belonged to parents residing within Dar es Salaam city: 12 were African, two Arabs and one was an Indian. the M.F ratio was 6'5:1. The approximate incidence rate was found to be one in 5,500 births. The majority presented with the characteristic clinical picture of the surgical condition and all were managed by the standard Fredet-Ramstedt pyloromyotomy. Mortality was 6.7pc.
