Care for patients who have undergone one anastomosis gastric bypass surgery

14 February 2019
Volume 28 · Issue 3


Thousands of bariatric surgery procedures are performed in the UK each year, including gastric bypass surgery. The one anastomosis gastric bypass (OAGB) is increasingly performed in the UK, and nurses may find themselves providing care for patients who have undergone this procedure. This article outlines the anatomical and physiological changes associated with OAGB, routine care of these patients in the short and long term, and the identification and management of complications.

Bariatric surgery is now firmly established in the UK with several thousand procedures being performed every year (Welbourn et al, 2014). One anastomosis gastric bypass (OAGB) is a recognised bariatric procedure (De Luca et al, 2018; Mahawar et al, 2018a) accounting for the third highest number of bariatric procedures worldwide (Angrisani et al, 2018) and being performed by an increasing number of British surgeons (Parmar et al, 2016). Nurses working in a variety of clinical settings might come in contact with patients who have undergone this bariatric procedure and be called on to care for them. This makes it important for nurses to be aware of the anatomical and physiological changes associated with this procedure, routine care of these patients, and the identification and management of complications.
