Abdominal plain film before gastrostomy tube placement to predict success of percutaneous endoscopic procedure

Gastrostomy tubes: Fundamentals, periprocedural considerations, and best practices

Gastrostomy tube placement is a procedure that achieves enteral access for nutrition, decompression, and medication administration. Preprocedural evaluation and selection of patients is necessary to provide optimal benefit and reduce the risk of adverse events (AEs). Appropriate indications, contraindications, ethical considerations, and comorbidities of patients referred for gastrostomy placement should be weighed and balanced. Additionally, endoscopist should consider either a transoral or transabdominal approach is appropriate, and radiologic or surgical gastrostomy tube placement is needed. However, medical history, physical examination, and imaging prior to the procedure should be considered to tailor the appropriate approach and reduce the risk of AEs.

Preoperative Evaluation Is Not Predictive of Transpyloric Feeding Conversion in Gastrostomy-dependent Pediatric Patients

OBJECTIVES

Limited literature exists as to whether preoperative gastrostomy (GT) evaluation may predict which patients will go onto require gastrojejunostomy (GJ) tube feeding. The goal of this study was to compare the preoperative evaluations between patients maintained on GT feeds versus patients who required conversion to GJ feeds.

METHODS

We identified patients at Boston Children's Hospital who underwent GT tube placement and required GJ feeding between 2006 and 2012. GT patients were matched according to age, neurologic, and cardiac status with GJ-converted patients. Preoperative characteristics, rates of total hospitalizations, and respiratory-related admissions were reviewed.

RESULTS

A total of 79 GJ patients (median interquartile range (IQR): age 15 (4.3, 55.7) months; weight 8.8 (4.6, 14.5) kg) were matched with 79 GT patients (median (IQR): age 14.6 (4.7, 55.7) months; weight 8.5 (5, 13.6) kg). Median time from GT to GJ conversion was 8 (IQR 3, 16) months. Both groups had similar rates of successful preoperative nasogastric feeding trials (GT (84.5%) versus GJ (83.1%), P = 1.0), upper gastrointestinal series (GT (89.1%) versus GJ (93.2%), P = 0.73), abnormal videofluoroscopic swallow studies (GT (53.8%) versus GJ (62.2%), P = 0.4), and completion of gastric emptying studies (GT (10.1%) versus GJ (5.1%), P = 0.22). No differences were seen in preoperative hospitalization rates (P = 0.25), respiratory admissions (P = 0.36), although GJ patients had a mean reduction in the number of hospitalization of -1.5 ± 0.5 days, P < 0.001, after conversion.

CONCLUSIONS

No differences in preoperative patient characteristics or diagnostic evaluations were seen in GT fed versus GJ converted patients. GJ patients did experience an overall decrease in total admissions after GJ conversion.

Use of upper gastrointestinal series before gastrostomy tube placement

We studied the use of a preoperative upper gastrointestinal series in children with and without major congenital anomalies undergoing gastrostomy tube (G-tube) placement. Of 1163 children evaluated, 743 had major anomalies and a total of 39 episodes of malrotation were found. All of the children with malrotation had either major congenital anomalies or cystic fibrosis. Our study suggests that an upper gastrointestinal series may be unnecessary before G-tube placement in children without other congenital anomalies or cystic fibrosis.
