Severe jejunoileitis after placement of a feeding jejunostomy: a series of four cases and a review of the literature

Is Roux-en-Y Feeding Jejunostomy a Safe and Effective Operation in Children? A Systematic Review Exploring Outcomes

OBJECTIVES

Roux-en-Y jejunostomy (REYJ) may establish feeding in children with foregut dysmotility or severe gastro-esophageal reflux disease (GERD). Nevertheless, concerns have been raised about safety and efficacy. We, therefore, evaluated outcomes of REYJ by systematic review to determine if this was a satisfactory option for achieving enteral autonomy in children with complex nutritional needs.

METHODS

A PRISMA-adherent systematic review was conducted of studies reporting children undergoing feeding REYJ. Two authors performed processes independently; the senior author resolved disagreements. Embase, CINAHL and Medline were searched (inception-01/21). Additional databases, references, and 'grey' literature were searched. Methodological Index for Non-randomized Studies (MINORS) and a bespoke system assessed methodological quality.

RESULTS

Of 362 articles, 10 met eligibility criteria (9 retrospective series; 1 conference proceeding). Unpublished data were also attained. Interobserver agreement for MINORS (kappa = 0.47) and bespoke scoring (kappa = 0.58) were moderate. After consensus, median MINORS score was 37.5% (IQR 6.3%) and bespoke 50% (IQR 20.8%), indicating poor methodological quality. One hundred sixty-four patients were reported (age range: 2 months to 19 years). Time to full feeds and length of stay were inadequately reported but most achieved enteral autonomy. No studies reported patient/caregiver-questionnaires. Seventy-six complications were documented (Clavien-Dindo grading was infeasible). Morbidity included peristomal leakage (N = 26), internal hernia/volvulus (N = 8), and SSI (N = 7). Thirty-eight patients died (2 procedure-attributable) during follow-up (range: 1 month to 15 years).

CONCLUSIONS

Up to 50% patients experience complications after REYJ (often minor) with 23% patients dying during follow-up, often comorbidity-attributable. REYJ can achieve enteral autonomy although parents/caregivers of children should be counselled accordingly.

Major complications of jejunal feeding in children

AIM OF THE STUDY

The aim of the study was to identify major gastrointestinal complications associated with direct jejunal feeding. We hypothesized that jejunal feeding may cause life-threatening surgical complications in a minority of patients.

METHODS

All patients undergoing jejunal feeding between 1/2008 and 1/2018 at a pediatric surgical unit were identified retrospectively. Data sought from records included demographics, comorbidities, indications, feeding strategies, adverse events, and follow-up. Major surgical complications were defined by Clavien-Dindo grade ≥ IIIb and involving the GI tract (excluding changes of jejunal tube).

MAIN RESULTS

197 patients were identified (110 female). Median age (IQR) at initiation of jejunal feeding months was 5.6 (6-164) months. 122 were neurologically impaired. The most frequent indications were: GERD/gastroparesis (n = 114), prophylaxis/treatment of Superior Mesenteric Artery (SMA) syndrome (N.B. our center is a national spinal deformity unit) (n = 47), congenital anomalies of aerodigestive anatomy (n = 17), and malignancy (n = 7). 125 patients were managed with nasojejunal feeding alone: gastrojejunal tube (n = 51) and via Roux-en-Y jejunostomy (n = 21). There were 14 significant gastrointestinal complications (n = 11 grade > IIIb) identified among 12 patients, of whom 8 required bowel resections, and 2 died as a result: nonmechanical bowel ischemia (n = 7), intussusception (n = 4), and volvulus (n = 3).

CONCLUSION

This series highlights the major complications of jejunal feeding, including a significant yet underreported risk of gut compromise. Patients undergoing jejunal feeding had a 6.1% risk of developing major surgical complications (of note, 3.6% developed bowel ischemia of unknown etiology). Susceptible children were comorbid, fragile, and neurologically impaired. These findings should influence parental discussions and informed consent before embarking upon jejunal feeding.

Gastrojejunostomy tube complications - A single center experience and systematic review

PURPOSE

Gastrojejunostomy tubes (GJTs) enable enteral nutrition in infants/children with feeding intolerance. However, complications may be increased in small infants. We evaluated our single-institution GJT complication rate and systematically reviewed existing literature.

METHODS

With REB approval, a retrospective single-institution analysis of GJT placements between 2009 and 2015 was performed. For the systematic review, MOOSE guidelines were followed.

RESULTS

At our institution, 48 children underwent 154/159 successful insertions primarily for gastroesophageal reflux (n=27; 55%) and aspiration (n=11; 23%). Median age at first GJT insertion was 2.2years (0.2-18). Thirty-five (73%) had an index insertion when ≤10kg. GJTs caused 2 perforations and 1 death. The systematic review assessed 48 articles representing 2726 procedures. Overall perforation rate was estimated as 2.1% (n=36 studies, 23/1092, 95% CI: 1.0-3.2). Perforation rates in children <10kg versus ≥10kg were estimated as 3.1%/procedure (95% CI: 1.1%-5.0%) and 0.1%/procedure (95% CI: 0%-0.3%), respectively. The relative risk of perforation was 9.4 (95% CI: 2.8-31.3). Overall mortality was estimated as 0.9%/patient (n=39 studies; 95% CI: 0.2-1.6%). Most perforations (19/23; 83%) occurred ≤30days of attempted tube placement.

CONCLUSION

Gastrojejunostomy tubes are associated with significant complications and frequently require revision/replacement. Insertion in patients <10kg is associated with increased perforation risk. Caution is warranted in this subgroup.
