Augmentation of Hiatal Repair with the Ligamentum Teres Hepatis for Intrathoracic Gastric Migration After Bariatric Surgery
2021
Overview
PurposeThe augmentation of hiatoplasty (HP) with the ligamentum teres hepatis (LTA) is a new concept for intrathoracic migration of a gastric sleeve or pouch (ITGM). We retrospectively analyzed all cases of hiatal hernia repair in a single center between 2015 and 2019.MethodsA total of 171 patients underwent 307 hiatal hernia repairs after sleeve gastrectomy (SG) (n = 79), Roux-en-Y gastric bypass (RYGB) (n = 129), and one anastomosis gastric bypass (OAGB) (n = 99). Each hiatal hernia repair was defined as a “case” and assigned to the LTA group or the non-LTA group. The primary outcome was the recurrence of ITGM as detected by endoscopy or CT.ResultsThe basic characteristics in the LTA group (78 cases) and the non-LTA group (229 cases) were comparable with the exception of the rate of revisional HP (72% vs. 21%), the rate of prior conversion to RYGB (33% vs. 17%), the initial BMI (45.9 ± 8.2 kg/m2 vs. 49.0 ± 8.8 kg/m2), and the follow-up (7 months (1–16) vs. 8 months (1–54)). The ITGM recurrence rate was 15% in the LTA group and 72% in non-LTA group (p < 0.001). Multivariate analysis showed that the length of ITGM and the type of surgical repair were independent risk factors. The addition of LTA to HP lowered the probability of ITGM recurrence by a factor of 0.35 (p = 0.015), but the conversion from SG or OAGB to RYGB did not reduce the risk.ConclusionsLTA reduces the risk of early ITGM recurrence. The long-term durability, however, needs to be further investigated.
