Elderly male patient with stomach cancer with feeding tube inserted into…
Elderly male patient with stomach cancer with feeding tube inserted into his alimentary canal to bypass the esophagus, stomach, and duodenum.
Downstream cause.
the food will lack most essential enzymes that were supposed to be found in the food for easy breakdown into various forms
-
Upstream cause
stomach. The food given with tube feeding already is mixed up and most of it broken down hence the stomach dont have much work to do
Pharynx. This organ is bypassed its function of swallowing hence food given through G tube is not correctly channeled in almentary canal to give enough time to be squeezed and channeled down the stomach.
Mouth. This organ is bypassed which help in eating food hence the enzyme lingual lipase is not involved in breaking down triglycerides hence this enzyme need to be added in the feeding tube.
Background information
Physiology
- Pharynx, help to move food from mouth to esophagus
- Stomach,Help in mixing and breaking down of food by contraction and relaxation of muscle layers
- Esophagus contract in order to move food to the stomach.
- Small intestine, help in absorption of nutrients and minerals from food
- mouth, help in eating and speaking.
6.Large intestine, Help in recovery and electrolytes. Also help with formation and storage of faeces and fermentation of indigestible food matter by bacteria.
Anatomy
-
- Organ; Small intestine, it is along narrow folded and coiled tube to increase surface area
- Organ; Pharynx, it a cone- shaped passageway leading from oral and nasal cavities in the head to the esophagus
- Organ;Large intestine, consists of cecum, colon, rectum, and anal canal.
2.Organ; Esophagus is a muscular tube connecting the throat (pharynx) with the stomach with four layers
- Organ; mouth is an oval- shaped cavity inside the skul
