Outcomes of Infantile Hypertrophic Pyloric Stenosis at Tertiary Care Centre

Abstract

Background and aims Infantile hypertrophic pyloric stenosis IHPS is a common infantile disorder characterized by enlarged pyloric musculature resulting in obstruction of gastric outlet and the most common cause requiring surgery in infants for vomiting. This study aimed to describe the clinical characteristics of infants with infantile hypertrophic pyloric stenosis its management and outcome.Methods This prospective observational study was conducted in our institute over a period of three years from February 2017 to January 2020. Fifty infants presented with diagnosis of Idiopathic hypertrophic pyloric stenosis who subsequently underwent surgical procedure were included in the study. Clinical presentation electrolyte abnormalities on admission ultrasound findings treatment and outcomes of treatment postoperative complications length of hospital stay and mortality were recorded in the study.Results A total of 50 patients were admitted and operated during the period of study. Male to female ratio was 5.21. Mean birth weight of the infants was 3.1 plusmn 1.4 kg. The mean age at presentation was 5.2 plusmn 1.2 weeks. Progressive non-bilious vomiting was the most frequent symptom 100. Metabolic alkalosis was seen in 32 64 infants. Electrolyte abnormality was seen in 38 76 infants. On ultrasound examination mean thickness of pyloric circular muscle was 5.2 plusmn 1 mm and mean length of pyloric muscle was of 20.1 plusmn 3 mm. Most common complication after surgery was septicemia followed by postoperative vomiting and wound infection.Conclusion High index of suspicion is required in infants with non-bilious vomiting to avoid delay in the diagnosis and its sequelae like dehydration and electrolyte imbalance.nbsp
