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.

Preoperative prevention
“one ounce of prevention is worth a pound of cure
• Rule out other conditions mimiking GERD
• Rule out IBS and / or FBD
i.e.: extensive functional work up
• Detailed informed consent and patients’ education
• Beware of patients with
– Atypical symptoms
– Normal 24-h pH studies
– Urgency in requiring the operation

Conclusions
• The laparoscopic treatment of hyatal hernia and
(complicated and uncomplicated) GERD is valid
and accepted by the scientific community and the
patients.
• The failure rate of such therapy depends on
different causes, and may reach 20% and more.
• However, only about half of these patients require
revisional surgery, having the others beneficial
effects from medical and endoscopic therapy.
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.
