The use of postoperative upper GI series (UGIS) after laparoscopic Roux-en-Y gastric bypass (LRYGBP) varies among bariatric surgeons. The authors describe the findings and impact of UGIS after LRYGBP.From July 2003 to January 2006, 487 patients undergoing primary LRYGBP at a single academic institution had a single-contrast Gastrografin UGIS performed on the first postoperative day, without complication. Patient and operative demographics were: mean age 43 years, mean BMI 47 kg/m2, female 84%, and laparoscopic 100%.Of the 487 patients, the UGIS revealed 14 (2.9%) major and 88 (15.2%) minor abnormalities. Among the major UGIS abnormalities, 6 (1.2%) demonstrated a gastrojejunal anastomotic (GJA) leak, 8 (1.4%) confirmed complete obstruction at the GJA, and 1 (0.2%) disclosed a communication with the bypassed stomach. For the minor UGIS abnormalities, 45 (9.2%) displayed significant delay in contrast passage through the GJA, 23 (5.0%) had evidence of dilated loops of small and/or large bowel, and 6 (1.2%) verified miscellaneous abnormal findings (malrotation, lower esophageal dysmotility, jejunal clots). Patients with UGIS abnormalities necessitated additional procedures, delayed oral intake and/or longer length of stay (LOS).UGIS on postoperative day 1 is a useful means of evaluating postoperative LRYGBP anatomy and influenced postoperative care.
