The position of the stomach in the cranial abdomen makes exteriorisation difficult. Anatomy General Surgical Principles The stomach is divided into four areas, which are important to identify when performing gastro-intestinal surgery. The cardia is the region where the oesophagus blends into the stomach. The fundus is the large out-pouching of the stomach along the greater curvature. The body of the stomach lies between the fundus and the pylorus and forms the reservoir of the stomach. The pylorus is the distal third of the stomach or the outflow tract. The pylorus is divided into two parts the thin walled antrum of the pylorus and the thick muscular pyloric sphincter. Remember Halsted’s principles of surgical technique minimise tissue trauma, practise precise haemostasis, preserve the blood supply, use aseptic technique, minimise tension on the tissue, use accurate tissue apposition and obliterate dead space.
