Laparoscopic repair of hiatal hernia.

BACKGROUND: Laparoscopic hiatal hernia repair is a complex surgery typically performed by general abdominal surgeons because it typically involves an abdominal approach. Here, we report our experiences on laparoscopic repair of hiatal hernia as thoracic surgeons. METHODS: Based on our experience of minimally invasive esophageal surgery (MIES) for esophageal cancer, we began performing laparoscopic repair of hiatal hernia in 2009. We analyzed the surgery-related data and postoperative outcomes of 18 consecutive patients we operated on from 2009 to 2017. RESULTS: There were 1 male and 17 female patients with a median age of 73 years (range, 37-81 years). Ten of 14 symptomatic patients experienced reflux symptoms, such as heartburn. Four patients had a history of prior abdominal surgery. Hiatal hernia types I, II, III, and IV were observed in 3, 9, 5, and 1 patients, respectively. Two (11.1%) laparoscopic procedures required conversion. Modified Collis gastroplasty was used as an esophageal lengthening procedure in 5 patients (27.8%). Mean operation time was 213.8±70.1 minutes and mean hospital stay was 6.2±1.5 days. There were no postoperative complications. At the last follow-up, 15 patients (83.3%) were asymptomatic; however, 3 (16.7%) complained of reflux or dysphagia. Recurrent hiatal hernia was detected on an esophagogram in only 1 patient at 3.5 years after laparoscopic surgery. CONCLUSIONS: Laparoscopic repair of hiatal hernia is a feasible technique with a satisfactory surgical outcome. Importantly, it can be performed by thoracic surgeons who are experienced in the laparoscopic approach.
