Complications of laparoscopic antireflux surgery.

Over the last decade, the laparoscopic approach to antireflux surgery has been widely applied, resulting in improved early outcomes and greater patient acceptance of surgery for gastroesophageal reflux disease. However, although short-term outcomes are probably better overall than those following open surgery, it has become apparent that the laparoscopic approach is associated with an increased risk of some complications, and as well as the occurrence of new complications specific to the laparoscopic approach. Significant complications include acute paraesophageal hiatus herniation, severe dysphagia, pneumothorax, vascular injury, and perforation of the gastrointestinal tract. The incidence of some of these complications decreases as surgeons gain experience; others can be minimized by using an appropriate operative technique. In addition, laparoscopic reintervention is usually straightforward in the 1st postoperative week. For this reason, the surgeon should have a low threshold for early laparoscopic reexploration, facilitated by early radiological contrast studies, in order to reduce the likelihood that problems will arise later.
