Demographics, comorbidities, and intra- and postoperative hospital course were collected.

These patients with mean age 44.1\u00a0years were majority female (71.1%) and white race (60.5%). Of the 24 patients where the RYGB was done at our institution, the mean RYGB to IH interval was 43\u00a0months. Petersen\u2019s defect (57.8%) followed by jejuno-jejunal mesenteric defect (31.6%) were the most common locations for IH. Both Petersen\u2019s and jejuno-jejunal mesenteric hernias were found in 4 cases (10.5%). Revision of bypass and small bowel resection were required in 13.2% and 5.3% of cases, respectively. The median (interquartile range) length of stay (LOS) was 2\u00a0days. On the multivariate analysis, male sex ( P = .019), conversion to exploratory laparotomy ( P = .005), and resection of small bowel ( P &lt; .001) were independent risk factors for increased LOS.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The most common location of IH after RYGB is Petersen\u2019s defect, followed by jejuno-jejunal mesenteric defect.
