Document Summary
Oesophagus: ~25cm long muscular tube that connects the pharynx to the stomach. Extends from the lower border of cricoid cartilage to the cardiac orifice of the stomach. Is pushed slightly to right by descending aorta at about t4/5. Then carries on downwards anterior to descending aorta. T10, 2-3cm to left and 4-5cm inferior to xiphisternal joint. Its abdominal portion is about 3cm in length. Ct - soft tissue detail, 3d, structure relationship. Us - superficial (bones absorb signal) thus combined with endoscopy (lymph node involvement for surgery) Double contrast barium esophagram and endoscopy: evaluating mucosal disease (inflammation, superficial tumour) Can be due to infections caused by candida, herpes, hiv, etc. Ba(cid:396)(cid:396)ett"s oesophagus: (cid:396)eti(cid:272)ula(cid:396) (cid:373)u(cid:272)osa is a (cid:272)ha(cid:396)a(cid:272)te(cid:396)isti(cid:272) Strictures (hiatal hernia in >95% of patients with strictures) Reflux esophagitis: gerd, condition which the oesophageal sphincter is unable to keep the acidic contents of the stomach causing backflow of acid which causes damage to the oesophagus.
