In about 1 in 5 patients at some stage the tumour begins to compress the duodenum (the part of the intestine immediately beyond the stomach). This often comes on gradually and presents with discomfort after eating, which is often relieved by vomiting. Fluids are better tolerated than solids, but because the stomach gradually stretches vomiting may only occur once every few days. Weight loss is common, as any food eaten cannot reach the part of the intestine where it is absorbed.
This operation is called a ‘gastro-jejunostomy’. You will have a general anaesthetic and your surgeon may use keyhole surgery (a laparoscopy) or make a small incision in your stomach called a mini-laparotomy. In order to bypass the duodenum, he/she will then connect another piece of small bowel, called the jejunum, directly to the stomach.
Recovery from a gastro-jejunostomy is usually fairly quick. You will be able to start drinking fluids the evening after your operation and gradually start to eat foods. You should be able to go home two or three days after your operation, once you are bale to eat and drink without any problems.
After a bypass operation
You may be cared for in a high dependency unit (HDU) before going back to the ward. You may be able to start drinking fluids in the evening after your operation and gradually start to eat foods. You will be able to go home once your eating and drinking has improved
