Abstract:
The infant was born at a gestational age of 28 + 2 weeks as second twin to a 26-year-old woman, G1/P0, due to eclampsia. The patient developed well and was on full oral feeds when he started to develop nonbilious vomiting at 5 weeks. He was diagnosed with pyloric hypertrophy and underwent pylorotomy, but the condition did not improve and the patient was referred to our hospital. Here, esophagogastroduodenoscopy showed severely inflamed esophageal and gastric mucosa which was found to be due to cytomegaly virus (CMV) infection and a nonpassable pylorus. The patient underwent pyloroplasty revealing a fibrous pyloric ring. Histology showed giant cells suggestive of CMV infection which was confirmed by polymerase chain reaction. He was started on valganciclovir and discharged 4 weeks later on full enteral feeds. To our knowledge, this is the first case of gastric outlet obstruction due to CMV infection in a premature infant.

Gastritis-II: Pathophysiology
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
