Delays in presentation of intussusception and development of gangrene in Zimbabwe

Introduction

prompt diagnosis and treatment are considered key to successful management of intussusception. We examined pre-treatment delay among intussusception cases in Zimbabwe and conducted an exploratory analysis of factors associated with intraoperative finding of gangrene.

Methods

data were prospectively collected as part of the African Intussusception Network using a questionnaire administered on consecutive patients with intussusception managed at Harare Children´s Hospital. Delays were classified using the Three-Delays-Model: care-seeking delay (time from onset of symptoms to first presentation for health care), health-system delay (referral time from presentation to first facility to treatment facility) and treatment delay (time from presentation at treatment facility to treatment).

Results

ninety-two patients were enrolled from August 2014 to December 2016. The mean care-seeking interval was 1.9 days, the mean health-system interval was 1.5 days, and the mean treatment interval was 1.1 days. Mean total time from symptom onset to treatment was 4.4 days. Being transferred from another institution added 1.4 days to the patient journey. Gangrene was found in 2 (25%) of children who received treatment within 1 day, 13 (41%) of children who received treatment 2-3 days, and 26 (50%) of children who received treatment more than 3 days after symptom onset (p = 0.34).

Conclusion

significant care-seeking and health-system delays are encountered by intussusception patients in Zimbabwe. Our findings highlight the need to explore approaches to improve the early diagnosis of intussusception and prompt referral of patients for treatment.

Overview of Anorectal Malformations in Africa

Anorectal malformation is one of the most common structural congenital malformations treated by pediatric surgeons globally. The outcome of care is largely dependent on the spectrum, clinical features, associated malformations, expertise of the surgeons, and available perioperative facilities. Africa has a large burden of unmet surgical needs in children, and as in other low resource settings, local pediatric surgeons are faced with different and challenging clinical scenarios, hence, adopt various measures to enable children with surgically correctable congenital malformations to survive. There are increasing collaborations between local surgeons and experts in other continents, which often involves surgeons traveling to Africa on missions or well-structured partnerships. It is highly beneficial for the physician who is interested in global-surgery to understand the terrain in low resource settings and prepare for possible changes in management plan. This review highlights the epidemiology, clinical presentation, treatment, and outcome of care of children with anorectal malformations in Africa and provides options adopted by pediatric surgeons working with limited resources.
