RESUMEN
BACKGROUND: High-output enterocutaneous fistula or enterostomies can cause intestinal failure. There is a wide variety of options in medical management of patients with high output. AIM: To systematically review the literature on available pharmacotherapy to reduce output and to propose an algorithm for standard of care. METHODS: Relevant databases were systematically reviewed to identify studies on pharmacotherapy for reduction in (high-) output enterostomies or fistula. Randomised controlled trials and within subjects controlled prospective trials were included. An algorithm for standard of care was generated based on the outcomes of the systematic review. RESULTS: Two studies on proton pump inhibitors, six on anti-motility agents, three on histamine receptor antagonists, one on an α2- receptor agonist and eight on somatostatin (analogues) were included. One study examined a proton pump inhibitor and a histamine receptor antagonist within the same patients. Overall, we found evidence for the following medical therapies to be effective: omeprazole, loperamide and codeine, ranitidine and cimetidine. On the basis of these outcomes and clinical experience, we proposed an algorithm for standard of care which consists of high-dose proton pump inhibitors combined with high-dose loperamide as the first step followed by addition of codeine in case of insufficient output reduction. So far, there is insufficient evidence for the standard use of somatostatin (analogues). CONCLUSIONS: The available evidence on the efficacy of medication to reduce enterostomy or enterocutaneous fistula output is hampered by low quality studies. We propose an algorithm for standard of care output reduction in these patients.

BACKGROUND: Type 2 acute intestinal failure is characterized by the need for parenteral nutrition (PN) for several months, and is typically caused by complications of abdominal surgery with enteric fistulas or proximal stomas. This study aimed to evaluate clinical management according to quality indicators established by the Association of Surgeons of Great Britain and Ireland. METHODS: Consecutive patients with type 2 intestinal failure referred to a specialized centre were analysed. Outcomes included the rate of discontinuation of PN, morbidity and mortality. RESULTS: Eighty-nine patients were analysed, of whom 57 had an enteric fistula, 29 a proximal stoma (6 with distal fistulas), and three had intestinal failure owing to other causes. One patient was deemed inoperable, and nine patients died from underlying illness during initial management. Before reconstructive surgery, 94 per cent (65 of 66 operated and 3 patients scheduled for surgery) spent the period of rehabilitation at home. Discontinuation of PN owing to restoration of enteral autonomy was achieved in 65 (73 per cent) of 89 patients. Seven patients developed a recurrent fistula, which was successfully managed with a further operation in four, resulting in successful fistula takedown in 41 of 44 patients undergoing fistula resection. Three patients (5 per cent) died in hospital after reconstructive surgery. The overall mortality rate in this series, including preoperative deaths from underlying diseases, was 16 per cent (14 patients). CONCLUSION: Intestinal failure care and reconstructive surgery resulted in successful discontinuation of PN in the majority of patients, although disease-related mortality was considerable.
