Enterocutaneous fistula treatment: case report and review of the literature.

Objective The aim of this work is to evaluate the treatment strategies for a common major complication like the fistula (ECFs). Since there is not any standard treatment for this common disease and since new therapies, like NPWT and sealants, have come up a review of all their indications seemed useful. We also present two clinical cases treated in this way. Patients and methods A research was made in the principle databases such as: Cochrane, Pubmed, Scholar and Google using the following Key words enterocutaneous fibrin glue, VAC, VAC fistula, conservative surgery and using the MESH Function to search similar key words and expand the research. When two or more article with the same design were encountered (e.g. systematic reviews or case reports etc.) the newest one was chosen as data source. Results As far as somatostatine and its analogues are concerned, they showed a significant reduction of both time (13.95 vs 20.5 days) and percentage (72% vs 44%) of fistula closure against placebo in 2 meta-analysis. NPWT showed a high success rate between 90% and 100% but longer closure time between 4 weeks and 6 months. Fibrin glues showed heterogeneous results due to the great differencies in fistulas anatomy and treatment technique in the various studies, with 64-100% success rate in closure and a median 11,25 vs 23,25 days against total parenteral nutrition (TPN) alone. Conclusions Because of ECFs often come up in patient in bad conditions who are not fitted for and because of their high Mortality and Morbidity, a multimodal approach is necessary. Although TPN is a cornerstone of their treatment, NPWT showed is superiority in reducing fistula output and in some cases leading to fistula closure, nevertheless it often needs long treating time. Fibrin glues often needs complex devices and are nota s good as NPWT in treating the around tissues, but they can be useful when fistulas are only accessible from a little external orifice or they show a complex branched tract; thus they are good when is not possible and the fistula has a mid- or low- output. The lack of prospective randomized studies or meta analysis and systematic review to compare the different methodics makes it impossible to show any evidence of superiority, but the combined application seems reasonable for a tailored treatment.
