PROMINENTLY IMPROVED PULMONARY FUNCTION AFTER OPERATION FOR AN ADVANCED GASTRIC CANCER WITH GASTRODUODENAL INTUSSUSCEPTION IN A PATIENT ON HOME OXYGEN THERAPY

Perioperative fluctuations in pulmonary function and nutritional state in a patient on home oxygen therapy (HOT) who had malneutrished for advanced gastric carcinoma which intussuscepted into the duodenum with ball valve syndrome are reported. An 83-year-old man, whose pulmonary function (FEV 1.0%) and undernourishment were rapidly deteriorating, was admitted to the hospital because of dyspnea, vomiting, and weight loss. After a distal gastrectomy, body weight, FEV 1.0%, and prognostic nutritional index were prominently inproved up to the state before HOT induction. In patients with latent chronic occlusive disease of the lung or those on HOT, determinant factors on the pulmonary function might be perioperative changes in nutritional state from preoperative malnutritional state due to associated malignancy to postoperative improved nutritional state along with improved feeding.
