 With the patient in the supine position, intubated under general anesthesia.  The endoscope was inserted without difficulty into the hypopharynx.  The scope was advanced down the esophagus, which had normal mucosal coloration and vascular pattern.  Lower esophageal sphincter was located at 40 cm from the central incisors.  It appeared normal and appeared to function normally.  The endoscope was advanced into the stomach, which was distended with excess air.  Rugal folds were flattened completely.  There were multiple superficial erosions scattered throughout the fundus, body, and antral portions consistent with Crohn's involvement of the stomach.  The endoscope was advanced through normal-appearing pyloric valve into the first, second, and third portion of the duodenum, which had normal mucosal coloration and fold pattern.  Biopsies were obtained x2 in the second portion of the duodenum, antrum, body, and distal esophagus at 37 cm from the central incisors for histology.  Two additional biopsies were obtained in the antrum for CLO testing.  Excess air was evacuated from the stomach.  The scope was removed from the patient who tolerated that part of the procedure well.
