Laparoscopic Appendectomy in Children: Preliminary Study in Pediatric Hospital Albert Royer, Dakar

Evolution of laparoscopic surgery in a sub-Saharan African country: a 30-year literature review in Senegal

INTRODUCTION

The advent of laparoscopy has significantly reduced the morbidity associated with the majority of abdominal surgeries. In Senegal, the first studies evaluating this technique were published in the 1980s. The objective of this systematic review is to assess the evolution of laparoscopy research in Senegal.

METHODS

A search of PubMed and Google Scholar was carried out without limit of publication date. The keywords used were "senegal" AND "laparoscop*". Duplicates were removed, and remaining articles were assessed for selection criteria. We included all articles about laparoscopy published in Senegal. The parameters studied in each included article were the place and year of study, average age, sex ratio, assessed indications and results.

RESULTS

41 Studies published between 1984 and 2021 met selection criteria. The average age of patients was 33 years (range 4.7-63). The sex ratio was 0.33. The main indications for laparoscopy according to the studies were: benign gastrointestinal disorders in 11 studies (26.8%), abdominal emergencies in 9 studies (22%), gallbladder surgery in 5 studies (12.2%), benign gynecological pathology in 6 studies (14.6%), malignant gynecological pathology in 2 studies (4.9%), diagnostic laparoscopy in 2 studies (4.9%), groin hernia repair in 2 studies (4.9%) and testicular pathology in 1 study (2.4%). Overall mortality was estimated at 0.9% (95% CI 0.6-1.3) and overall morbidity for all complications was estimated at 5% (95% CI 3.4-6.9).

CONCLUSIONS

This systematic review showed a predominance of the laparoscopy publications from the capital in Dakar with favorable outcomes. This technique should be popularized in the different regions of the country and its indications expanded.

The diagnostic value of hepcidin to predict the presence and severity of appendicitis in children

BACKGROUND

The aim of this study was to determine the diagnostic capacity of hepcidin in pediatric acute appendicitis and its accuracy as a predictor of the severity of appendicitis.

MATERIALS AND METHODS

In children with appendicitis (n = 39), leukocytes, platelet count, and the serum levels of C-reactive protein (CRP) and hepcidin were compared to a control group (n = 25) of patients with unspecific abdominal pain. Additionally, parameters were compared between children with simple (n = 17) and complicated appendicitis (n = 22). Receiver operation characteristic analyses of the different parameters were performed and the areas under the curve (AUCs) calculated.

RESULTS

Leukocytes and serum hepcidin levels were significantly higher in children with acute appendicitis versus control group (13.7 ± 5.7 versus 9.8 ± 3.9 G/L, P = 0.005 and 31.3 ± 21.7 versus 20.4 ± 14 ng/mL, P = 0.039). AUCs for hepcidin, leukocytes, and CRP were 0.654, 0.711, and 0.619, respectively. Complicated appendicitis was associated with significantly higher hepcidin concentrations compared to simple appendicitis (38.5 ± 17.6 ng/mL versus 21.6 ± 23.4 ng/mL, P < 0.001). A combination of leukocytes, CRP, and hepcidin had the highest AUC (0.914) to predict complicated appendicitis.

CONCLUSIONS

Increased serum levels of hepcidin were found in children with appendicitis compared to controls. While hepcidin was useful to identify patients with complicated appendicitis as it does not seem appropriate to distinguish between simple appendicitis and other causes for acute abdominal pain.
