Diagnosis codes from the International Classification of Diseases, 9th revision, Clinical Modification (ICD-9-CM), were used to define PUD in the following terms: peptic ulcer (533), gastric ulcer (531), gastrojejunal ulcer (534), and duodenal ulcer (532) (23).
pylori hospitalizations were examined by age group (<20, 20-44, 45-64, and [greater than or equal to]65 years of age), sex, race/ethnicity (white, black, Hispanic, and Asian or Pacific Islander), geographic region (Northeast, Midwest, South, and West), designated ulcer type (peptic, gastric, gastrojejunal, and duodenal), other diagnoses listed along a PUD diagnosis, and procedures.
Either some proximal holes of the tube would be in the lower esophagus, or some of the distal holes would have traversed the gastrojejunal anastomosis and be located in the Roux limb.
This gastrojejunal anastomosis is usually about 10 mm in diameter, only about twice the diameter of a 16 Fr tube (5.
61-63) Anastomotic stricture at the gastrojejunal
anastomosis is seen on fluoroscopy as narrowing at the gastrojejunal
anastomosis, with expansion of the gastric pouch and delayed transit of contrast into the Roux limb.
