Comparison of the outcome of laparoscopic procedures for GERD

A total laparoscopic fundoplication has become the procedure of choice for the surgical treatment of gastroesophageal reflux disease in patients with normal esophageal motility, with reduced postoperative pain, faster recovery and similar long-term outcomes compared to conventional open total fundoplication. Most controversial surgical aspects are the division of the short gastric vessels and the insertion of a bougie to calibrate the wrap. The anterior 180° and the posterior partial fundoplications lead to similar control of heartburn when compared to total fundoplication with lower risk of dysphagia. However, when performed, 24-h pH monitoring shows pathologic reflux more frequently after partial than total fundoplication. Disappointing results are achieved by anterior 90° partial fundoplication. More recently, a magnetic sphincter augmentation with the LINX Reflux Management System (Torax Medical) and the lower esophageal sphincter Electrical Stimulation (EndoStim) have been developed, seeking for a durable and effective minimally invasive alternative to laparoscopic fundoplication for the treatment of reflux. Both devices seem to be promising, with very low postoperative complications and good short-term functional outcomes. Large randomized controlled trials comparing them with laparoscopic fundoplication over a long period of follow-up are needed to verify their indications and outcomes.
