Sténose hypertrophique du pylore en chirurgie pédiatrique du Centre Hospitalier Universitaire Sylvanus Olympio LoméTogo

Objective-the aim of this study was to determine the hospital frequency of hypertrophic pyloric stenosis and the socio-demographic characteristics of patients with HPS, to describe the clinical and therapeutic aspects and to evaluate the operative follow-up. Methods-This was a retrospective descriptive study conducted over aperiod of 06 years and 06 months (January 2014 to June 2020) in the pediatric surgery department of the Sylvanus Olympio Teaching Hospital in Lomé. Complete records of patients from 0 days to 30 months of age hospitalized and managed for HPS during the study period were included. Epidemiological, anamnestic, clinical, paraclinical, therapeutic and evolutionary data were studied. Results-a total of 17 patients were collected in the department. The hospital incidence of HPS was approximately 3 cases per year. The predominance was male. The mean age of the patients was 40.4 ± 15.1. Vomiting of curdled milk was the main reason for consultation. Ultrasound was performed in all patients and was diagnostic in the majority of patients (15 patients). The ionogram was disturbed in 14 patients, hypochloremia being the mostcommon ion disorder. Management consisted on open Fredet and Ramstedt extramucosal pylormyotomy in all patients. The supra-umbilical approach was the most commonly used. All patients had a favourable outcome. Conclusion-hypertrophic pyloric stenosis was characterised by a delay in consultation with a clinical picture dominated by vomiting causing ionic disorders. However, the encouraging therapeutic results noted could be improved.
