Background: High-output double enterostomies (DESs) result in sodium and fluid loss responsible for frequent episodes of dehydration and hospitalizations. Hydration by enteroclysis (HE) is an alternative to parenteral hydration when the small bowel, or the downstream colon, is accessible and functional., Methods: A retrospective analysis was conducted on all consecutive patients admitted in our institution with high-output (≥1200 ml per 24 h) DES and access to downstream intestine (including colon), who were treated by enteroclysis between 2015 and 2019. A sodium chloride and bicarbonate solution was instilled through a tube inserted in the colon. The objectives were diuresis >1 L, natriuresis >40 mmol/24 h, and urinary sodium-to-potassium ratio >1., Results: HE was conducted in 52 patients (24 female, 28 male). Initially, 30 patients received intravenous support. Fifteen patients (50%) were weaned from all parenteral support, of whom 11 of 12 (92%) received fluid and electrolyte support and 4 of 18 (22%) received parenteral nutrition (PN). When intravenous fluids were still required, daily volumes decreased from 2714 ± 1424 to 1578 ± 1000 ml per 24 h (P = .001), as did the energetic intake (NS), from 1439 ± 556 to 1230 ± 362 kcal per 24 h (P = .096)., Conclusion: HE through the efferent intestine limits the requirement for parenteral hydration in patients with high-output DES. For patients with intestinal failure dependent on PN, it reduces daily infused volumes., (© 2021 American Society for Parenteral and Enteral Nutrition.)

Background and Aims: Automated chyme reinfusion (CR) in patients with intestinal failure (IF) and a temporary double enterostomy (TDE) restores intestinal function and protects against liver injury, but the mechanisms are incompletely understood. The aim was to investigate whether the beneficial effects of CR relate to functional recovery of enterohepatic signaling through the bile salt-FGF19 axis., Approach and Results: Blood samples were collected from 12 patients, 3 days before, at start, and 1, 3, 5, and 7 weeks after CR initiation. Plasma FGF19, total bile salts (TBS), 7-α-hydroxy-4-cholesten-3-one (C4; a marker of bile salt synthesis), citrulline (CIT), bile salt composition, liver tests, and nutritional risk indices were determined. Paired small bowel biopsies prior to CR and after 21 days were taken, and genes related to bile salt homeostasis and enterocyte function were assessed. CR induced an increase in plasma FGF19 and decreased C4 levels, indicating restored regulation of bile salt synthesis through endocrine FGF19 action. TBS remained unaltered during CR. Intestinal farnesoid X receptor was up-regulated after 21 days of CR. Secondary and deconjugated bile salt fractions were increased after CR, reflecting restored microbial metabolism of host bile salts. Furthermore, CIT and albumin levels gradually rose after CR, while abnormal serum liver tests normalized after CR, indicating restored intestinal function, improved nutritional status, and amelioration of liver injury. CR increased gene transcripts related to enterocyte number, carbohydrate handling, and bile salt homeostasis. Finally, the reciprocal FGF19/C4 response after 7 days predicted the plasma CIT time course., Conclusions: CR in patients with IF-TDE restored bile salt-FGF19 signaling and improved gut-liver function. Beneficial effects of CR are partly mediated by recovery of the bile salt-FGF19 axis and subsequent homeostatic regulation of bile salt synthesis., (© 2021 The Authors.

Background & Aims: High output entero-cutaneous fistulas may lead to intestinal failure with parenteral nutrition (PN) as the gold standard treatment to prevent dehydration and malnutrition. However in case of entero-atmospheric fistula (EAF) with the distal limb of the fistula accessible, chyme reinfusion (CR), a technique that restores artificially digestive continuity can be performed until the surgical repair. Our aim was to study the efficacy of CR in EAF regarding nutritional status, intestinal function, PN weaning and liver tests., Methods: Retrospective study of 37 patients admitted for EAF and treated by CR from 1993 to 2017. Delays were expressed in median (25%-75% quartiles) and other data on mean ± SD., Results: Location of EAF: jejunum (29), ileum (8). The length of the upstream intestine was estimated in 21 patients: 19 had a bowel length <150 cm of which 16 had less than 100 cm. During CR, mean digestive losses decreased from 1734 ± 578 to 443 ± 487 ml/24 h (p < 0.000001), nitrogen absorption increased from 45.3 ± 18.6 to 81.8 ± 12.9% of ingesta (p < 0.001). The percentage of patients with plasma citrulline <20 µmol/l decreased from 71 to 10%. PN was stopped in all patients within 3 (0-14) days after CR initiation, 2 patients required an intravenous hydration and 20 had an additional enteral support. The nutritional status improved: albumin (33.1 ± 5.1 g/L vs 28.4 ± 6.5, p < 0.001), NRI (decrease of the number of patients at risk of severe malnutrition from 22 to 10 (p < 0.001)). The number of patients who had one or several liver tests abnormalities (>2 N) decreased from 94 to 41% (p < 0.001)., Conclusion: When the efferent part of the small bowel is accessible, CR is a safe and inexpensive method that restores bowel function. In most cases, it makes it possible to stop PN and helps to improve the nutritional status until surgical reconstruction., Competing Interests: Conflicts of Interest None for any of the authors., (Copyright © 2020 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.

Some temporary double enterostomies (DES) or entero-atmospheric fistulas (EAF) have high output and are responsible for Type 2 intestinal failure. Intravenous supplementations (IVS) for parenteral nutrition and hydration compensate for intestinal losses. Chyme reinfusion (CR) artificially restores continuity pending surgical closure. CR treats intestinal failure and is recommended by European Society for Clinical Nutrition and Metabolism (ESPEN) and American Society for Parenteral and Enteral Nutrition (ASPEN) when possible. The objective of this study was to show changes in nutritional status, intestinal function, liver tests, IVS needs during CR, and the feasibility of continuing it at home. A retrospective study of 306 admitted patients treated with CR from 2000 to 2018 was conducted. CR was permanent such that a peristaltic pump sucked the upstream chyme and reinfused it immediately in a tube inserted into the downstream intestine. Weight, plasma albumin, daily volumes of intestinal and fecal losses, intestinal nitrogen, and lipid absorption coefficients, plasma citrulline, liver tests, and calculated indices were compared before and during CR in patients who had both measurements. The patients included 185 males and 121 females and were 63 ± 15 years old. There were 37 (12%), 269 (88%) patients with EAF and DES, respectively. The proximal small bowel length from the duodeno-jejunal angle was 108 ± 67 cm ( n = 232), and the length of distal small intestine was 117 ± 72 cm ( n = 253). The median CR start was 5 d (quartile 25-75%, 2-10) after admission and continued for 64 d (45-95), including 81 patients at home for 47 d (28-74). Oral feeding was exclusive 171(56%), with enteral supplement 122 (42%), or with IVS 23 (7%). Before CR, 211 (69%) patients had IVS for nutrition (77%) or for hydration (23%). IVS were stopped in 188 (89%) 2 d (0-7) after the beginning of CR and continued in 23 (11%) with lower volumes. Nutritional status improved with respect to weight gain (+3.5 ± 8.4%) and albumin (+5.4 ± 5.8 g/L). Intestinal failure was cured in the majority of cases as evidenced by the decrease in intestinal losses by 2096 ± 959 mL/d, the increase in absorption of nitrogen 32 ± 20%, of lipids 43 ± 30%, and the improvement of citrulline 13.1 ± 8.1 µmol/L. The citrulline increase was correlated with the length of the distal intestine. The number of patients with at least one liver test >2N decreased from 84-40%. In cases of Type 2 intestinal failure related to DES or FAE with an accessible and functional distal small bowel segment, CR restored intestinal functions, reduced the need of IVS by 89% and helped improve nutritional status and liver tests. There were no vital complications or infectious diarrhea described to date. CR can become the first-line treatment for intestinal failure related to double enterostomy and high output fistulas., Competing Interests: The authors declare no conflicts of interest.

Background & Aims: Patients with double temporary enterostomy may suffer from intestinal failure (IF). Parenteral nutrition (PN) is the gold standard treatment until surgical reestablishment of intestinal continuity. Chyme reinfusion (CR) is a technique consisting in an extracorporeal circulation of the chyme. The aims were to determine: i) whether CR could restore intestinal absorption, decrease PN needs, improve nutritional status and plasma liver tests; ii) the feasibility of home CR., Methods: From the 232 patients IF consecutively referred for CR from 2000 to 2014, the 212 patients with IF, technical feasibility of CR, and effectively treated by CR, were included. Were collected prospectively before and during CR: daily stomal and fecal outputs, coefficients of nitrogen (CNDA) and fat (CFDA) digestive absorption, weight loss, body mass index (BMI), Nutritional Risk Index (NRI), plasma albumin, citrulline, and liver tests., Results: 183 patients had temporary double enterostomy and 29 exposed enterocutaneous fistulas. CR reduced the intestinal output (2444 ± 933 vs 370 ± 457 ml/day, P < 0.001), improved CNDA (46 ± 16 vs 80 ± 14%, P < 0.001) and CFDA (48 ± 25 vs 86 ± 11%, P < 0.001), and normalized plasma citrulline concentration (17.6 ± 8.4 vs 30.3 ± 11.8 μmol/l, P < 0.001). PN was stopped in 126/139 (91%) patients within 2 ± 8 d. Nutritional status improved (P < 0.001): weight (+4.6 ± 8.6%), BMI (+3.8 ± 7.7%), plasma albumin (+6.2 ± 6.1 g/l), and NRI (+10.9 ± 9.5). The proportion of patients with plasma liver tests abnormalities decreased (88 vs 51%, P < 0.01). Home CR was feasible without any serious complications in selected patients., Conclusions: CR corrected the intestinal failure by restoring intestinal absorption, allowing PN weaning in 91% of patients. CR contributes to improve nutritional status and to reduce plasma liver tests abnormalities, and is feasible at home., (Copyright © 2016 Elsevier Ltd and European Society for Clinical Nutrition and Metabolism.
