Prevalence, Management and Outcomes of Enterocutaneous Fistulas in Buea Regional Hospital and Laquintinie Hospital of Douala. A Five Years Retrospective Study

Abstract

Background: An Enterocutaneous fistula (ECF) is an abnormal connection between the intestinal tracts or stomach and the skin. They are a major catastrophe to the patient and surgeons and still have a high incidence of morbidity and mortality which varies between 6% - 33%; their management remains a big challenge. These patients frequently face complications, and a well-or ganized multidisciplinary approach must be implemented in their management to improve outcomes . Objectives: Our study aims to assess the preva lence, management and outcomes of enterocutaneous fistulas in Buea regional hospital and Laquintinie hospital of Douala over the past 5 years. Methods: This was a hospital-based retrospective study in Buea regional hospital and Laquintinie hospital of Douala. Records of patients who had enterocutaneous fistulas within the period of 1 st January 2017 to 31 st December 2020 in the surgical departments. Data included demographics, pre-operative diagnosis, comorbidities, type of fistula, management modality and means, the indica tion of operative treatment, length of stay in the hospital and outcomes. Data was analysed using SPSSv26. Results: The study constituted 1343 medical records of which 83 medical records of patients with enterocutaneous fistulas, giving a prevalence of 6.2%, female predominance at 59% (n = 49), 42.2% (n = 35) were referred cases from the periphery for better management. A vast majority (96.4%) occurred as post-operative complications with appendectomy the most common indication (18.8%). High output fistulas were predominant (43.4%). 59% (n = 47) were managed medically, 6% (n = 5) received both conservative and surgical modalities while 35% (n = 5) were managed surgically. 64.1% (n = 50) were placed on enteral nutrition while 35.9% (n = 28) were placed on parenteral nutrition. Peritonitis/infection 50% (n = 18) was the commonest indication of surgical treatment, followed by failure of medical treatment 25% (n = 9) then high output fistulas 16.7% (n = 6). Resection with end-to-end anastomosis was the preferred repaired work at 61% (n = 22). The mortality rate was 38.5% (n = 32), 29% (n = 24) healed after conservative treatment, 21.7% (n = 18) healed after surgery, 7.2% (n = 6) persisted after surgery while 3.6% (n = 3) persisted after conservative treatment. Anaemia, sepsis, electrolyte imbalance, dehydration and malnutrition were the commonest complications. Conclusion: The prevalence of enterocutaneous fistulas was high, with a female predominance and a mean age of 38 years. Most cases were seen as a referral from the periphery for better management. The greatest majority of fistulas occurred as a postoperative complications. Conservative management with enteral feedings was preferred, they had better outcomes and gave more chances of healing. The commonest indication of surgical treatment was an infection. Resection with end-to-end anastomosis was the preferred repaired work. The mortality rate was high, and anaemia, sepsis and electrolyte imbalance were the commonest complications.
