Hello doctor,

I have an old patient who is my father aged 75 years old who is diabetic and having hypertension. He has pain in the stomach especially after eating and having serious weight loss. We decided to have an endoscopy last year and they found sliding hiatal hernia and we went for the barium swallow which showed some signs of achalasia and now today we went for a second round endoscopy which showed the result as G.O.O 2° Tumor at Pylorus and he suggested for gastrojejunostomy as a plan or conclusion. We are referred to a different specialist but we are yet to book an appointment, we are so anxious. We are fearing a pancreatic cancer.



Welcome to icliniq.com.

I feel sorry to hear about your father. I can imagine it must be very tough time on you and other family memebers in this time. Well GOO stands for Gastric outlet obstruction. Yes, the common cause of it is pancreatic cancer, stomach cancer. The pylori is secondarily involved due to tumor and not the primary source of tumor. The surgical gastrojujunostomy can be performed by a surgeon, but it have certain risks in his age, as any procedure with anesthesia have.

The alternative safe option in such cases is endoscopic gastroduodenal stent. This would be performed by endoscopist and one of the safe method with low risk. You should discuss with the gastroenterologist in your vicinity.
