“…Like other major surgical interventions, bariatric surgery is associated with risk. Although the severity of complications has decreased as a result of improvements in technology, 3–5% of bariatric patients have been reported to need reoperations due to acute complications such as internal herniation, gastric anastomosis leak, and pulmonary and venous embolism (Groven, 2014 ; Hadam, Somers, & Chand, 2011 ; Hofsø 2011 ; Mala & Kristinsson, 2013 ; Nasjonalt kunnskapssenter for helsetjenesten, 2014 ; Natvik, 2015 ).
