Objective: The optimal surgical treatment of paraesophageal hiatal hernia is in debate. Our experience with a traditional transthoracic approach was reviewed to provide "benchmark" data against which newer surgical techniques can be measured.
Methods: Between 1977 and 2001, 240 patients had primary transthoracic repair of paraesophageal hiatal hernia. Presenting complaints included reflux (69%), pain (67%), dysphagia (36%), and bleeding or anemia (33%). Preoperative esophageal function testing showed abnormal reflux in 86%. Hernia types were combined (type III) in 92% and type IV in 8%. All patients had reduction of the hernia and a concomitant antireflux procedure. An esophageal lengthening Collis gastroplasty was performed in 96%.
Results: There were 3 perioperative deaths (1.7%). The median length of hospital stay was 7 days. Early complications requiring reoperation occurred in 12 patients (5%) and included recurrent hernia in 4, leak in 3, and a tight hiatal closure in 3. Mean follow-up in 226 patients was 42 months (median 27.8 months). Satisfactory results were obtained in 86% of patients. Follow-up complaints (moderate or persistent symptoms) included dysphagia (4), reflux (1), dumping (3), and post-thoracotomy pain (1). Routine postoperative barium radiographs showed intact repair in 71% (108/153). Of 19 patients with an anatomic recurrence, 4 (2%) had more than a partial asymptomatic migration of the fundoplication and required reoperation. Postoperative esophageal function testing, obtained in 28% of the patients, showed abnormal gastroesophageal reflux in 2.
Conclusion: Open transthoracic repair of paraesophageal hiatal hernia provides good to excellent long-term control of both the hernia and gastroesophageal reflux with relatively low early morbidity.
