BACKGROUND: The use of routine upper gastrointestinal contrast radiology series (UGIS) after laparoscopic Roux-en-Y gastric bypass surgery (LRYGB) can entail risk, expense, and patient discomfort. We have discontinued routine UGIS in favor of selective UGIS guided by patient symptoms and signs or elevations in the juxta-anastomotic drain amylase. We hypothesized that elimination of routine UGIS would not adversely affect morbidity or mortality. METHODS: We retrospectively reviewed the anastomotic leak, reoperation, and death rates and length of hospital stays for all patients who underwent LRYGB between two periods when either routine (November 2003 to December 2004) or selective (January 2005 to February 2006) postoperative UGIS were done. RESULTS: In group 1, were 267 patients who had undergone LRYGB with routine UGIS during November 2003 to December 2004. Group 2 consisted of 151 patients who had undergone LRYGB with selective UGIS during January 2005 to February 2006. The mean +/- standard error of the mean hospital stay for groups 1 and 2 was 4.3 +/- 0.3 and 3.3 +/- 0.2 days (P = .08), respectively. In group 1, 18 gastrojejunostomy leaks (6.7%) occurred compared with 6 (4.0%) in group 2 (P = .28). Also, 14 patients (5.2%) in group 1 required reoperation for anastomotic leak compared with 3 (2.0%) in group 2 (P = .13). Three patients (1.1%) in group 1 and no patients in group 2 died (P = .56). CONCLUSION: The elimination of routine UGIS did not adversely affect morbidity or mortality. The mean hospital stay in the group with selective UGIS decreased, although this decrease had not yet achieved statistical significance.
