Purpose. To determine the possibility and feasibility of robotic surgical system (RSS) in the treatment of the patients with hiatal hernias. Material and methods. A total of 37 patients (mean age 56.2±10.9 years) were included. There were 22 (60%) patients with cardiofundal, 13 (35%) — subtotal, and 2 (5%) — total hiatal hernias (HH). 18 (48%) patients had concomitant diseases: gastric and/or duodenal ulcer in 8 (22%), cholelithiasis in 7 (19%) and Barrett’s esophagus with low grade dysplasia in 4 (11%) cases. All patients underwent robot-assisted fundoplication in A.F. Chernousov modification, with cruroplasty without mesh insertion. All procedures were performed by one operating team at RSS DaVinci Si (Intuitive Surgical, Sunnyvale, CA). Results. Average operation time was 122±37 min. Average blood loss was 20±9 ml. There were no conversions to open or laparoscopic procedures and re-intervention in early postoperative period. Cruroplasty performed 31 (85%) patients, in 10 (26%) cases not only posterior, but also anterior. Average hospital stay was 5.0±1.3 days. Average follow-up period was 14.0±3.6 months. In long-term follow-up period there were no recurrence of hiatal hernia or gastroesophageal reflux. Conclusion. We can conclude that robot-assisted surgery is safe, appropriate and justified in patients with cardiofundal, subtotal and total hiatal hernia. We believe that use of RSS in treatment of patients with reflux esophagitis and/or cardiac hiatal hernia is unjustified, due to the lack of proven advantages over laparoscopy.
