Gastric diverticula are the least common gastrointestinal diverticula. Patients can be diagnosed incidentally on EGD or present with variable symptoms such as abdominal fullness, anorexia, and perforation. Gastric diverticula can be acquired from malignancy, peptic ulcer disease, or prior surgery or be congenital. Treatment varies based on symptomatology ranging from conservative medical management with proton pump inhibitors to surgical treatment with open or laparoscopic resection. We present a case of a 73-year-old female with acquired gastric diverticulum presenting as a gastric outlet obstruction who was successfully treated with conservative medical therapy.
