ABSTRACT
Introduction
Enterocutaneous fistulas (ECFs) is a manifestation of penetrating Crohn’s disease (CD) that is challenging to treat and has considerable morbidity and mortality rates.
Areas covered
This review aims to explore the practical and updated principles for the optimal treatment of ECFs in CD patients.
Expert opinion
Optimal ECF management requires a multidisciplinary approach. Treatment first includes fluid resuscitation and electrolyte rebalancing with control of sepsis by means of antibiotics and, when indicated, drainage of infected collections. Subsequent therapeutic steps include nutritional support, control of the fistula output and treatment of peristomal skin. Anti-TNF-α therapy seems to have limited utility only after sepsis is resolved and intestinal stenosis excluded. However, ECFs heal in only approximately one-third of cases without surgical intervention. Thus, correct surgical timing combined with adequate nutritional support, sepsis resolution and skin care is considered the appropriate preoperative setting.
Article highlights
Enterocutaneous fistulas (ECFs), although rarer than perianal fistulas, are among the most feared manifestations of penetrating CD since they are associated with significant morbidity and mortality
The treatment of ECFs in CD patients is a challenge for physicians and requires a multidisciplinary approach to obtain satisfactory results and minimize consequences and recurrences
Sepsis resolution is the most important prognostic factor for the healing of ECFs; thus, intensive treatment is mandatory.
The correction of malnutrition and prevention of specific nutrient deficiency by the adoption of effective nutritional support is of paramount importance in patients with ECFs.
The psychological support of patients with ECFs must necessarily complement conventional therapies, nutrition and nursing care. The optimal timing of surgery for ECFs is crucial for subsequent outcomes, such as postoperative morbidity, recurrence and mortality.
The control of fistula output should be attempted as far as possible since the amount of enteric loss is a crucial prognostic factor for ECF healing.
The psychological support of patients with ECFs must necessarily complement conventional therapies, nutrition and nursing care.The optimal timing of surgery for ECFs is crucial for subsequent outcomes, such as postoperative morbidity, recurrence and mortality.
