Management of Pediatric Abdominal Surgical Emergencies in Northern Benin ()
1. Introduction
In the pediatric environment, the diagnosis of abdominal surgical emergencies (ASE) is a real challenge for the surgeon, due to the usual severe prognosis [1] [2]. The success of their care depends on the organization put in place. Unfortunately in Africa, pediatric surgery is not yet developed. Therefore, almost all cases are treated in adult surgical department. The main determinants identification and the management, morbidity and mortality assessment of pediatric abdominal surgical emergencies could lead to a real clinical and health interest.
2. Patients and Methods
This is a prospective, descriptive and analytical study realized in Parakou teaching hospital and Tanguieta district hospital. The study covered a period of 7 months from January 1st 2016 to July 31st 2016. Were included children aged from 0 to 15 years and admitted for an abdominal surgical emergency with a clinical classification of patients with emergencies (known as CCMU: Classification Clinique des Malades aux Urgences) quoted at 3, 4 or 5. CCMU is a score that allows the evaluation of patients in care in emergency department [3]. It comprises 7 degrees of severity: CCMU P (patient with a psychiatric pathology); CCMU 1 (patient considered stable); CCMU 2 (patient considered stable with a decision of complementary diagnostic or therapeutic act); CCMU 3 (patient whose condition is likely to worsen without being life-threatening); CCMU 4 (patient whose vital prognosis is engaged without need of imperative resuscitation maneuver); CCMU 5 (patient whose vital prognosis is engaged with imperative necessity of a resuscitation maneuver); CCMU D (deceased patient without any resuscitation maneuver). The distribution of children in age groups was the following: new-borns (0 to 28 days); infants: (29 days to 30 months); children (after 30 to 120 months) and adolescents (beyond 120 months).
The variables studied were the diagnosis delay, the preoperative resuscitation duration, the time for surgical management, the indication for surgery; complications and mortality. The time elapsed between the admission and the diagnosis was the diagnosis delay and the one between the diagnosis and the surgical procedure beginning, the time for surgical management. The delay in surgical management is defined by an operative time beyond the “Time of Acute Care Surgery (TACS)” defined by the “World Society of Emergency Surgery (WSES)” [4].
Collected data was analyzed using the Epi Info 7.2 software. Statistical tests used were arithmetic variance, Chi2 and FISHER test. For comparisons, a probability p < 0.05 was considered as statistically significant.
3. Results
3.1. Sociodemographic and Diagnostic Data
68 cases of pediatric abdominal surgery emergency (PASE) were recruited, representing 42.8% of surgical emergencies in children and 27.6% of pediatric surgical activities. There were 43 boys (63.2%) and 25 girls (36.8%) with a sex ratio at 1.7. The average age was 9.3 ± 3.5 years with the extremes 1 day and 15 years. The average time for consultation was 5 days. The emergencies included non-traumatic abdominal surgical emergencies (NTASE), 83.8%, and traumatic abdominal surgical emergencies (TASE), 16.2%. Table 1 shows the distribution of these different emergencies.
3.2. Therapeutic Data
The average resuscitation duration was 22.8 ± 1 hours with extremes 25 minutes and 11 days. Out of the 68 children who had abdominal surgical emergencies, 62 were operated representing a percentage of 91.2%.
The average time for surgical management was 22 hours with the extremes 20 minutes and 10.8 days. Table 2 shows that there was a delay in surgical management for all categories of interventions. Many factors were associated with that delay such as the patient age (p = 0.07); the pathology severity (p = 0.7); the lack of technical means (p = 0.01) and the lack of proficient personnel (p = 0.6). The different surgical procedures performed are shown in Table 3.

3.3. Evolutive Data
During preoperative resuscitation, 6 deaths occurred, representing 8.8% of preoperative deaths. Neonatal period and resuscitation time higher than 36 hours significantly influenced preoperative death (p = 0.027 and p = 0.035, respectively). For operated children (n = 62), post-operative history was complicated in 9.7% (n = 6). There were 3 cases of deep suppuration, 2 two of parietal suppuration and one of postoperative peritonitis. The postoperative mortality rate was 4.8% (n = 3).
4. Discussion
4.1. Sociodemographic and Diagnostic Data
The average age of the patients in this study was 9.3 years. That age is similar to the one reported from a study conducted by Pujari et al. in India [5] and Abantanga et al. in Ghana [1] respectively at 7 and 8.8. The sex ratio at 1.7 is close to 1.5 found by Abantanga et al. [1] and Abubakar et al. in Nigeria [6].
The average time for consultation was 5 days. This is superior to 2 days reported by the Harouna et al. in Niger [7] and 4 days in the Nigerian series by Abubakar et al. [6]. Delay in consultation is frequent in our context as reported in many other previous studies in sub-Saharan Africa [8] [9] [10]. It would be related to many factors including ignorance of parents, prior use of traditional medicine and sometimes to misdiagnosis.
4.2. Therapeutic Data
22.8 hours as resuscitation duration was very long in the context of the severe emergencies. It had led to the death of six children. In fact, the resuscitation time greater than 36 hours significantly influenced preoperative death (p = 0.035). The neonatal period also influenced the occurrence of death during preoperative resuscitation (p = 0.027).
The time for surgical management was 22 hours. Basing on WSES classification [4], we were able to conclude that the average time for surgical management was not adequate. This delay in management was mainly due to the inadequacy of the technical capacities (p = 0.01).
As peritonitis is the main diagnosis, it directed the majority of surgical procedures toward excision, intestinal suture with washing and drainage. Perforation is very common in Africa and associated with typhoid fever. Typhoid fever is a disease encountered in regions with low socioeconomic level and leads to ileal perforation as complication [11]. Colostomy according to Pena was the colostomy technique performed in case of anorectal malformation and it was effective given the absence of postoperative complication in our study.
4.3. Evolutive Data
Postoperative morbidity in our study was 9.7% with a deep suppuration predominance. In Niamey, Harouna Y et al. [7] reported a rate of 55% among infants treated for intussusception in a general surgery department in 2000. They attributed this very high rate to the delay in diagnosis, the problems of resuscitation and the lack of pediatric surgeon. Postoperative mortality is low compared to 23% reported by Matoko et al., [12] and 22.8% by Mhando S et al. [13].
5. Conclusion
Pediatric abdominal surgical emergencies mostly affected boys and the time for consultation was long. Peritonitis and anorectal malformations were the main diagnoses in our context. Operative management was delayed, mainly due to the lack of adequate technical capacities. Morbidity and mortality were relatively low in comparison with other series.
