Hydration by colonic enteroclysis: An alternative to parenteral hydration in patients with high-output double enterostomy

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.

The mutually complementary role of magnetic resonance enterography and conventional enteroclysis in patients with complicated and/or advanced stage of Crohn's disease

AIM

To assess the diagnostic significance of magnetic resonance enterography (MRE) and conventional enteroclysis (CE) in patients with complicated and/or advanced stage of Crohn's disease.

METHODS

Patients with abnormal CE findings suggestive of mural and/or extramural involvement with the diagnosis or pre-diagnosis of CD are evaluated. After real-time bowel distension by enteroscopic examination, the patients with advanced or complicated stage were taken to the MRE examination in the same session. Mucosal-mural-extramural and activation findings, presence of stenosis/stricture, skip lesions and the mean duration of exams were evaluated with both CE and MRE. The superiority of one method over the other relative to these findings was evaluated.

RESULTS

A total of 110 patients evaluated by CE had the findings of CD. Of these, 24 patients with abnormal CE findings suggestive of advanced mural and extramural involvements were subsequently evaluated with MRE. CE was superior to MRE in the depiction of early superficial mucosal changes (aphthous-linear ulcer), cobblestone pattern (p = 0.002, p < 0.01), obstruction (p = 0.004, p < 0.01), and differentiation between the string sign and stricture. MRE was superior to conventional enteroclysis in mural and perienteric findings of bowel thickening, fibro-fatty proliferation, abscess (p = 0.016, p 0.05).

CONCLUSION

CE and MRE are mutually complementary imaging modalities in CD staging, evaluation of activation findings, and detection of complications (Tab. 3, Fig. 8, Ref. 23).

Refeeding enteroclysis as an alternative to parenteral nutrition for enteric fistula

AIM

Refeeding enteroclysis is one method of giving artificial nutritional support to patients with enterocutaneous fistula. This study compares the results of this technique with parenteral nutrition or nutrition given via a proximal stoma.

METHOD

All patients admitted to our intestinal failure unit with a proximal enteric fistula and managed with refeeding enteroclysis over a 4-year period were included and compared with a matched group of patients managed without using this technique.

RESULTS

Twenty patients (15 men) with a proximal enteric fistula received chyme refeeding down the distal limb of the fistula. This was established at a mean of 14 days after admission to the unit and total parenteral nutrition could be weaned off by 20 days. The mean output from the proximal limb was 1800 ml and the mean volume refed down the distal limb was 1220 ml per day. Additional enteric feed was given to 12 patients. No patient was given pharmacological agents to delay gastrointestinal transit or additional intravenous water and electrolyte for most of the time after refeeding was established. There were no complications or deaths related to chyme refeeding.

CONCLUSION

Refeeding enteroclysis is feasible in selected patients with a proximal enteric fistula or stoma. Adequate nutrition, water and electrolyte balance can be achieved without resorting to parenteral infusions.

Tubercular versus Crohn's ileal strictures: role of endoscopic balloon dilatation without fluoroscopy

BACKGROUND

Benign ileal strictures can cause considerable morbidity and they have been conventionally treated with surgery. The aim of this study was to report our experience of endoscopic balloon dilatation (EBD) in patients with terminal ileal strictures because of Crohn's disease and tuberculosis.

METHODS

Over the last 8 years, 9 patients (6 males; mean age 39.7±13.2 years) with benign terminal ileal strictures were treated by EBD using a colonoscope and through-the-scope controlled radial expansion balloon dilators.

RESULTS

The etiology of benign ileal stricture was Crohn's disease in 5 and tuberculosis in 4 patients. All the patients with Crohn's disease had no or partial response to 4 weeks of steroid therapy and there were no mucosal ulcerations on ileoscopy. Three patients with ileal strictures due to tuberculosis underwent dilatation after completion of the antitubercular therapy (ATT) while one patient required dilatation 3 months after starting ATT. All patients had single ileal stricture with length of stricture ranging from 0.6-1.8 cm. EBD was successful in all 9 patients with a median number of dilating sessions required of 2 (range: 1-5 sessions). Patients with Crohn's disease required more endoscopic sessions as compared to patients with tuberculosis but this difference was not statistically significant (mean number of session being 3.0±1.58 vs. 1.75±0.5 sessions respectively; P=0.1). One patient with ileal tuberculosis had enterolith proximal to the stricture that could be removed with dormia. There were no complications of the endoscopic procedure.

CONCLUSIONS

EBD is an effective, safe, and minimally invasive treatment modality for benign ileal strictures.

Contrast-induced acute kidney injury following iodine opacification other than by intravascular injection

Contrast-induced acute kidney injury (CI-AKI) classically occurs following the intravascular administration of iodinated contrast medium (CM). However, some cases of iodine-induced nephrotoxicity have been reported in patients who did not receive intravascular CM, as a consequence of iodine absorption through mucosae, burned skin or interstitial tissues. Recently, we observed the first case of CI-AKI occurring after an enteroclysis without any direct intravascular injection of CM. Here, we report this case, and review other clinical situations in which renal toxicity has been reported following the non-intravascular use of iodinated compounds.

CT enteroclysis in the diagnostics of small bowel diseases

BACKGROUND

The role of CT enteroclysis is gaining on importance in the diagnostics of small bowel diseases. The aim of the study was to present own experiences in CT enteroclysis application, with the use of a 64-detector CT unit.

MATERIAL/METHODS

CT enteroclyses were performed in 60 patients: 53 with the suspicion of the Crohn's disease, 2 suspected for carcinoid, 1 with suspicion of the fistula between the small bowel and the bladder, 2 suspected for the tumor of the ileo-caecal region, and in 1 case, the aim of examination was to carry out an evaluation of the postsurgical state of the bowel-bowel anastomosis. We used own endoscopic technique of catheter insertion into the bowel, which shortens the examination time and improves patient's comfort.

RESULTS

The catheter was correctly introduced into the small bowel in 58 patients (endoscopy had to be repeated in 4 cases). Only 2 examinations failed, because patients refused repeated endoscopy. Radiological signs of the Crohn's disease were found in 50 out of 53 patients. In the 3 remaining patients, the appearance of the small bowel was normal. In 5 non-Crohn's disease patients, CT enteroclysis enabled a good visualization of the pathology (tumors, fistula).

CONCLUSIONS

CT enteroclysis with the use of the 64-detector CT unit is a valuable method in the diagnostics of small bowel diseases. It could supplement or precede capsule endoscopy.

Dieulafoy's lesion of jejunum: presenting small bowel mass and stricture

Dieulafoy's lesion is an uncommon cause of gastrointestinal bleeding. Hemorrhage occurs through mucosal erosion from an abnormally dilated submucosal artery. Although Dieulafoy's lesion is usually located in the stomach, it may occur anywhere in the gastrointestinal tract. We report here on a case of jejunal Dieulafoy's lesion presenting as a mass and short segment stricture on CT and enteroclysis.
