Background/Aim:
Ensuring that postoperative gastric cancer patients receive sufficient oral nutritional supplementation (ONS) to prevent body weight loss (BWL) is a serious challenge. The present pilot study evaluated the feasibility and safety of small, frequent sip feeds (SIP) with super energy-dense ONS (SED ONS; 4 kcal/ml) in postoperative gastric cancer patients.
Patients And Methods:
Patients received 400 kcal/day of SED ONS in four, daily, 25 ml SIP for 12 weeks after gastrectomy. The primary outcome was the percentage of postoperative weight change. The expected mean weight change was 90% (10% standard deviation). A sample population of 14 patients, sufficient for a 95% confidence interval with a 10% margin of error, was enrolled.
Results:
The mean weight change for patients receiving SIP with SED ONS was 93.8%. The mean SED ONS intake was 348 kcal/day. Thirteen patients consumed more than 200 kcal/day of SED ONS. One patient with a mean intake of 114 kcal/day had undergone total gastrectomy followed by adjuvant chemotherapy.
Conclusion:
Small, frequent SIP with SED ONS was found to be feasible and safe in postoperative gastric cancer patients. A multicenter randomized controlled trial is warranted to determine whether SIP with SED ONS is effective in preventing BWL.
