Feeding the gut after revisional bariatric surgery: The fate of 126 enteral access tubes.

BACKGROUND

Revisional bariatric surgery (RBS) is associated with higher complication rates compared with primary bariatric surgery. Feeding tubes (FTs), including gastrostomy and jejunostomy tubes placed during RBS, may serve as a safety net to provide nutrition when oral intake is contraindicated or limited; however, FTs in this setting have not been well investigated.

OBJECTIVES

This study aims to determine complications, use, and duration of FTs placed during RBS.

SETTING

A high-volume academic medical center in the United States.

METHODS

Included patients underwent RBS between January 2008 and December 2016 with FTs placed at the time of RBS.

RESULTS

There were 126 patients identified (84.9% female, 76.2% Caucasian, mean age 53.4-±10.9 yr). Patients had previously undergone Roux-en-Y gastric bypass (34.1%), vertical banded gastroplasty (27.8%), and adjustable gastric band (14.3%). Indications for RBS included correction of complication of prior bariatric surgeries (50%), weight regain/failure to lose weight (32.3%), or both (17.3%). Most FTs were placed in the excluded stomach (89.7%), and median tube size was 18 F. FTs were used for feeding in 68.2% of patients, with feeding initiated in a median of 2 days. Leakage around the tube (32.5%) and pain (26.8%) were common complaints. Significant tube-related complications included infection (9.1%), dislodgement (5.9%), reintervention (5.8%), and reoperation (2.8%); 16.7% experienced at least 1 significant complication. FTs were removed at a median of 36 days.

CONCLUSION

FTs may aid in prevention of perioperative dehydration and malnutrition after RBS, but should not be considered a benign intervention. FT use should be balanced against institutional outcomes and care goals.
