A case of life-threatening, early postoperative refeeding syndrome in an obese young female undergoing laparoscopic sleeve gastrectomy

Abstract

Abstract Early complications after a laparoscopic sleeve gastrectomy (LSG) include bleeding, leaks, strictures and bowel obstructions. Patients post-LSG experience rapid but intended weight loss and may be on a restricted diet before and following surgery. Thus, many of these patients are in a malnourished state, placing them at a risk of developing potentially life-threatening refeeding syndrome (RFS). We describe the case of an 18-year-old female who developed RFS 2 weeks after LSG. We examine potential causes, review literature and discuss RFS pathophysiology as well as the guidelines that could help prevent RFS in bariatric surgery. Currently, not much is known about the risk of RFS in bariatric surgery and to our knowledge, this is the first report of RFS occurring in the early postoperative phase after LSG. A globally accepted definition of RFS should be established for guidelines to encompass wider patient groups.
