Abstract

Hiatal hernia (HH) repairs are commonly done concomitantly with laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic adjustable gastric banding (LAGB) to decrease gastroesophageal reflux disease (GERD). There is limited evidence about the additional surgical risk these combined procedures engender. We used the United States Nationwide Inpatient Sample 2004-2009 to compare mortality risk, prolonged length of stay (PLOS), and perioperative adverse events using propensity score-matched analysis. We repeated the analysis after removing patients diagnosed with GERD. There were 42,272 weighted patients undergoing LRYGB alone representing 206,559 discharges nationally and an additional 1,945 and 9,060, respectively, undergoing LRYGB+HH repair. For LAGB, there were 10, 558 records representing 52,901 LAGB-only discharges and 1,959 representing 9,893 LAGB+HH repair discharges. Thirty-eight percent (95 % CI: 36, 41 %) of the patients in the LRYGB-only group had GERD compared to 55 % (51, 59 %) in the LRYGB+HH repair group. Among the LAGB groups, 31 % (28, 34 %) of LAGB-only patients had GERD compared to 44% (38, 49%) in the LAGB+HH repair group. We find that the average treatment effect on the treated (considering the concomitant procedure as treatment and the single procedure as control) for PLOS was ?0.12353 (?0.15909, ?0.08797) between the LRYGB groups and ?0.04353 (?0.07488, ?0.01217) for the LAGB groups. We find no evidence of increased risk of perioperative adverse events among patients undergoing concomitant HH repair with LRYGB or LAGB. Patients undergoing the combined procedure appear to be at lower risk of PLOS; this may be due to surgical training norms.
