Background

Internal hernia is a known complication of enteric surgery with the creation of a roux limb. The risk of internal hernia is thought to be substantially lower following single anastomosis bariatric surgery. It is infrequently described in the literature but can be treated with the same surgical principles that apply to all internal hernia defects. As is the case with all internal hernias, a high level of clinical suspcion is necessary for the expeditious diagnosis and treatment of this malady.
