The Indian experience with hypertrophic pyloric stenosis

Area of Science:

• Pediatric Surgery
• Gastroenterology
• Infant Health

Background:

• Congenital hypertrophic pyloric stenosis (CHPS) is a common surgical emergency in infants.
• Understanding demographic and clinical variations across different populations is crucial for diagnosis and management.
• Previous studies have highlighted differences in CHPS presentation between Western and Asian populations.

Purpose of the Study:

• To investigate the clinical presentation and outcomes of CHPS in Indian infants.
• To compare these findings with established data from Western populations.
• To evaluate the diagnostic utility of physical examination and air contrast radiography.

Main Methods:

• A retrospective analysis of 58 consecutive Indian infants undergoing surgery for CHPS.
• Data collected included patient demographics, preoperative symptoms (e.g., hemetemesis), physical examination findings, and postoperative outcomes.
• Air contrast radiography was utilized for diagnosis in clinically ambiguous cases.

Main Results:

• A significant male predominance was observed in the Indian cohort.
• Preoperative hemetemesis was less frequent compared to Western counterparts.
• A palpable 'pyloric tumor' was detected in 89% of cases.
• First-born infants constituted 34.5% of the study population.
• Postoperative vomiting occurred in 13.8% of infants, with no instances of wound sepsis.
• Air contrast radiography proved effective in confirming diagnoses.

Conclusions:

• Indian infants with CHPS exhibit distinct epidemiological and clinical features, notably a higher male incidence and lower rates of preoperative vomiting.
• Palpation remains a highly sensitive diagnostic tool for CHPS.
• The findings underscore the importance of population-specific data in understanding and managing CHPS.
