Many nutritional interventions have been developed to improve nutritional outcomes following upper gastrointestinal surgery. The aim of this systematic review was to investigate whether or not the routine use of intraoperative jejunostomy feeding tubes in partial and total gastrectomy procedures is warranted when assessing complications and nutritional benefits such as improved chemotherapy tolerance. An electronic search of MEDLINE, Web of Science, Embase and CINAHL databases was performed to identify studies which reported complications and/or post-operative outcomes of patients who received an intraoperative jejunostomy feeding tube in gastrectomy procedures. Five articles met the inclusion criteria (n = 636) with four retrospective cohort studies and one RCT. Studies varied in regards to the complications and nutritional outcomes reported. Jejunostomy feeding tube insertion may carry a risk of increased infectious complications but appears to reduce patient post-operative weight-loss and may improve chemotherapy tolerance. Due to the lack of high-quality studies, it is unclear if the routine use of an intraoperative jejunostomy feeding tube is indicated for all patients undergoing gastrectomy procedures or only those at a high-risk of post-operative malnutrition. More comprehensive research is recommended, particularly on the usefulness of home enteral nutrition post-gastrectomy.
