Treatment of failures after antireflux surgery
Mario Costantini Università di Padova – Clinica Chirurgica 1^ (Dir. Prof. E. Ancona) Treatment of failures after antireflux surgery Background • Laparoscopic fundoplication has revealed as a valid alternative to medical treatment for GERD. • The number of patients undergoing laparoscopic fundoplication is continuously increasing. • In the same way, failures of this therapy are increasingly reported, also. • A better knowledge of the mechanisms of failure and of the related risk factors may help the surgeon prevent and/or treat some of these failures.

Conclusions Fundoplication dislocation is the most common cause of failure of laparoscopic antireflux surgery: • wider hyatal dissection • less adhesions • earlier mobilisation and return to daily activities of the patients • (large hyatal defects – giant hernias) • (“short” esophagus) • (pathology of muscle fibers of the crura?) Conclusions • Persistent dysphagia is probably related to incomplete mobilisation of the fundus and/or an uncorrect surgical technique. • In general, the reflux control is achieved in more than 90% of patients. • Beware of patients with atypical symptoms and who do not respond to medical therapy. • Gastrointestinal symptoms may be aggravated after fundoplication, but they are often present and require proper evaluation also before the operation.
