[Particularities of liver abscesses in children in Senegal: Description of a series of 26 cases].

UNLABELLED

Liver abscess is a serious infection that can cause life-threatening complications.

OBJECTIVE

To describe the epidemiology, diagnosis, and progression of liver abscess at the Dakar National Albert-Royer Children's Hospital.

METHOD

A retrospective study was conducted from over a period of 5 years (1st January 2010 to 31st December 2014). All children aged 0-15 years hospitalized for liver abscess with ultrasound confirmation were included. We collected demographic data (age, gender, socioeconomic status, origin), clinical data (general and hepatic symptoms), diagnostic data (ultrasound, bacteriology) and progression (death, complications, sequelae). The data were analyzed with Epi-info (P<0.05 was considered significant).

RESULTS

We collected 26 cases of liver abscesses, representing a hospital prevalence of 100 cases per 100,000 admissions. Males predominated (sex ratio: 1.36). The children's average age was 7.2 years. Most of the children came from urban areas of Dakar. Low socioeconomic status and precarious lifestyle were the contributing factors. Anemia (69.2%), malnutrition (42.3%), and abdominal trauma (15.3%) were the main causes found. The Fontan triad characteristic of the liver abscess was found in 57.7% of cases. At ultrasound, a single abscess was found in 21 cases. The abscess was located in the right lobe in 18 cases, the left lobe in three cases, and in both lobes in three cases. Segment VI (four cases) was the most frequently involved. Bacteriologically, the abscess was pyogenic in 17 cases and an amoebic abscess in nine cases. The main pyogenic sources found were Klebsiella pneumoniae in two cases, Pseudomonas aeruginosa in one case, Streptococcus pneumoniae in one case, and Staphylococcus aureus in one case. The average duration of antibiotic treatment was 14.5 days. Liver drainage was carried out in 24 cases. The outcome was favorable in all children.

CONCLUSION

The prevalence of liver abscesses at the Albert-Royer Children's Hospital is relatively high, compared to the literature data. Percutaneous drainage combined with antibiotics remains the treatment of choice. The prognosis is favorable.
