ObjectiveData on graded complications and their frequency after laparoscopic revisional antireflux and hiatal hernia surgery compared with primary surgery are lacking. We describe 30- and 90-day morbidity using the Clavien-Dindo classification.MethodsA total of 298 patients underwent revision surgery between 2003 and 2020 and were propensity matched to primary surgeries (1:2 ratio) based on age, sex, body mass index, American Society of Anesthesiology classification, Los Angeles grade esophagitis, presence of Barrett's, and indication for surgery. Complications were graded using the Clavien-Dindo classification, with the highest grade of complication reported per patient.ResultsAfter matching, both groups had a majority of female patients, with a median age of 60 years and a median body mass index of 29.5 kg/m2. Most were healthy, with nonerosive esophagitis and modest levels of Barrett's esophagus. A laparoscopic Nissen fundoplication was most common; however, a partial fundoplication was more common in revisions. Mesh, relaxing incisions, and Collis were more common in revisional surgery. At 30 days, total complications were similar (23.5% [70/298] vs 20.6% [123/596], P = .373) with 1 death in each group. Minor complications (less than Clavien-Dindo 3A) were comparable. Patients undergoing revisional surgery experienced Clavien-Dindo 3B complications (4.7% [14] vs 0.8% [5], P > .001) more frequently, with esophageal obstruction requiring revision and esophageal/gastric leak being most common. Grade Clavien-Dindo 4 A/B complications were comparable in both groups. At 90 days, patients undergoing revisional surgery experienced overall complications (7.1% [21] vs 2.0% [12], P = .003), and Clavien-Dindo 3B complications (1.0% [3] vs 0, P = .037) more frequently, with intra-abdominal abscess washout being the most common Clavien-Dindo 3B complication.ConclusionsRevisional surgery results in similar total complications at 30 days, but additional complications can occur out to 90 days.Copyright © 2024 The American Association for Thoracic Surgery.
