Role of robotic-assisted surgery in benign esophageal diseases.

Laparoscopic treatment of benign esophageal conditions is technically complex with several inherent limitations. Robotic-assisted surgery provides technical improvement and helps to overcome some of these limitations. We therefore report a single surgeon's experience in management of benign esophageal diseases by robotic-assisted surgery. Over a period of 8 consecutive years, a retrospective chart review was performed of 105 patients who underwent robotic-assisted surgery for benign esophageal diseases by a single surgeon. Demographic data and outcome measures were studied. The robotic-assisted procedures included 85 Nissen fundoplications with and without mesh repair, 12 Heller myotomies and eight para-esophageal hernia repairs. The mean total operating time was lowest for the Nissen group (94 min) and highest for the para-esophageal group (183 min). Operating time decreased from a mean of 105 min in the first 20 cases to 84 min in the last 20 cases for the Nissen group (P = 0.014). The mean length of stay was 1.3, 1.6, 1.5 and 4.8 days for the groups, respectively. Persistent symptoms of dysphagia/reflux/dysphonia requiring further investigation were seen in nine (8 %) of these patients. Two of these patients required repeat Nissen fundoplication in the mesh group. Our complication rate, total operating time and length of stay for robotic-assisted benign esophageal surgery are comparable to those reported in the literature. When performed by an experienced surgeon, robotic-assisted surgery is safe and effective in the management of benign esophageal diseases.
