Early experience in robot-assisted laparoscopic Heller myotomy.
Heller myotomy for achalasia is routinely performed laparoscopically. This offers patients significant benefits compared to open surgery. Surgeons, however, are limited in their manipulation and visualization during laparoscopic interventions. Robotic telemanipulation systems were introduced with the objective of alleviating these limitations. The purpose of this study was to demonstrate the efficacy and safety of performing a Heller myotomy with the use of a robotic telemanipulation system. Fourteen patients were operated on with the da Vinci robot system. Robotic system set-up time, per- and postoperative complications, blood loss, operating time and hospital stay were recorded. Follow-up included manometry and symptom score. The robotic system set-up time was 15 min (10-15). Thirteen procedures (13/14: 93%) were completed by laparoscopic surgery. One procedure was converted because of inadequate exposure. One peroperative mucosal perforation was closed laparoscopically. The median blood loss was 10 mL (10-200). Median operating time was 90 min (75-150). Hospitalization ranged from 2 to 8 days (median 3). No complications occurred during a 30-day postoperative period. Dysphagia was relieved in 12/14 patients (86%). Heartburn was present postoperatively in 2/14 patients (14%). Manometry showed a significant decrease in median lower oesophageal sphincter (LOS) pressure from 2.9 preoperatively to 1 kPa postoperatively (P = 0.008). Robot-assisted laparoscopic Heller myotomy was demonstrated to be safe and effective in reducing basal LOS pressure and dysphagia. The results of this study clearly support the feasibility of the use of this system in performing a delicate laparoscopic surgical procedure. The use of a robotic system was experienced as being highly supportive in manipulation and visualization by the surgical team involved.
