Du nouveau pour les reflux gastro-oesophagiens : une procédure chirurgicale non invasive, effectuée à l'aide d'instruments fabriqués par la société Endo Gastrics Solutions, va désormais être pratiquée en Europe.
EndoGastric Solutions™ launches the EsophyX™ Endoluminal Fundoplication device in Europe
Redmond, WA, June 19, 2006 - "EndoGastric Solutions Inc. (EGS), a leader in reconstructive intragastric surgery, announced today that its EsophyX™ device is now approved for commercialization in the EU and is ready for limited commercial release to 40 leading European centers during 2006."
"The technology created by EGS enables gastroenterologists and surgeons for the first time to perform true endoluminal fundoplication procedures for the treatment of GERD (gastro-oesophagal reflux disease), completely through a trans-oral ('natural orifice') approach, without any incisions. What makes this procedure unique is that it is based on the proven surgical principles of antireflux surgery such as the Nissen Fundoplication, enabling complete reconstruction of the natural antireflux barrier.
Dr. Guy-Bernard Cadière, Professor and Chief of Surgery at Centre Hospitalier Universitaire St-Pierre, the first surgeon to evaluate this new technology as part of EGS's clinical studies initially conducted at Hospital St. Pierre and Clinique du Parc Leopold - CHIREC in Belgium, stated today 'The limited commercial release of the EsophyX™ product, represents a milestone for trans-oral incisionless surgical repair of the anti-reflux barrier and provides the first promising alternative to traditional laparoscopic fundoplication for the definitive treatment of GERD.'
EGS has been testing the EsophyX™ device and improving the Endoluminal Fundoplication (ELF) procedure since June, 2005. The 6 month follow-up results using the first-generation EsophyX™ device in a phase 1 study have approached those obtained with more traditional laparoscopic Nissen fundoplications in terms of success at eliminating Proton Pump Inhibitor (PPI) drug dependence and protecting the esophagus from acid exposure (pH results).
The lead investigator, Professor Cadière, states 'The preliminary results to date for EsophyX™ are very encouraging. Over 80% of patients have normal or near normal pH at 6 months post-ELF procedure despite discontinuing their GERD medications. Over 90% of patients show an improvement in quality of life and a reduction in GERD symptoms compared to before their ELF procedure and over 80% of patients remain off of PPI drugs at an average follow-up period of 10 months post-procedure. 70% of patients remain off any sort of GERD medication.'
'If these results continue to hold up,' Professor Cadiére continues, 'we could easily imagine that up to 20% of all GERD patients worldwide could benefit from natural orifice surgery such as the EsophyX™ Procedure.'
Thierry Thaure, President and Chief Executive Officer of EGS said today, 'We are extremely pleased with our progress at EndoGastric Solutions and believe that we are well on our way to being able to prove that it is not only possible but also easier to complete an endoluminal fundoplication procedure from inside the stomach. As the EsophyX™ product and Endoluminal Fundoplication (ELF) procedure mature, we intend to accomplish what the Laparoscopic Nissen failed to do, deliver a mainstream antireflux procedure to the general surgical and interventional gastrointestinal market.'
GERD is acid reflux with heartburn that is frequent and severe enough to impact daily life and damage the esophagus. Normally, after swallowing a valve between the esophagus and stomach opens to allow food to pass into the stomach, and then closes to prevent reflux of the food back into the esophagus. In GERD, this valve is weakened or absent, causing the acidic digestive juices from the stomach to flow back (or reflux) into the esophagus. This reflux is not only dangerous, because the esophagus is made of delicate tissue that cannot withstand the caustic, acidic contents of the stomach, but it is also painful, and 'burns' the throat (and is therefore called 'heartburn'). Reflux of these stomach contents can also lead to a precancerous condition called Barrett's esophagus and/or adenocarcinoma, a full blown cancer that is very aggressive and deadly.
Drug Treatment of GERD
Current medical treatment of GERD includes drugs, such as H2 blockers and proton pump inhibitors, which neutralize or suppress the stomach acid and help relieve symptoms. However, these drugs are expensive, they don't work for everyone, and many people who do respond quit responding over time. Although over $13 billion are spent each year on proton pump inhibitors alone, these drugs do not correct the root cause of GERD (anatomic disintegration of the antireflux barrier) so symptoms return when the medication is stopped. More effective and permanent solutions are needed.
About Surgical treatment of GERD
Surgical treatment of GERD by long, open incisions on the abdomen or by laparoscopy (usually 5 ports or small holes in the abdomen) has long been known to effectively treat GERD. However, this surgery is invasive, with lots of cutting both inside the patient around the stomach area, and on the abdominal skin. This surgery, generally called Nissen or laparoscopic fundoplication, also has issues. The effectiveness of the Nissen procedure is highly dependent on surgeon skill, since the procedure is complicated, and effectiveness can be only half as good with inexperienced surgeons. The Nissen can also cause problems if it is done too tight, and patients can experience 'gas bloat syndrome' where they have cramps and pain and trapped gas. Other undesirable effects can include difficulty swallowing, painful swallowing and inability to burp or throw up. Despite these problems with the previous surgical approach (Nissen), the surgery is generally effective at reducing reflux by creating a valve at the base of the esophagus where it joins the stomach.
About Endoluminal Fundoplication (ELF) procedures
The primary commercially available treatments for gastroesophageal reflux disease (GERD) in Europe were medications or surgery, until recently, when the ELF procedure, an additional option that mimics surgery but involves no abdominal or internal incisions has become available. The EsophyX™ device by EndoGastric Solutions (EGS), is used to perform an endoluminal fundoplication (ELF). The ELF procedure involves going through the mouth to deliver fasteners in the stomach that create a 3-5 cm thick flap of tissue in 270° circumference at the base of the esophagus. This flap valve is what rests closed against the other side of the stomach at the junction of the stomach to the esophagus, to prevent stomach contents from refluxing back into the esophagus. Patients who have reflux disease generally have lost this flap valve and the junction of their esophagus to their stomach has stretched out and allows food to reflux or regurgitate back into the esophagus. These patients generally need an anatomical reconstruction to relieve their GERD symptoms. The ELF procedure, performed using the EsophyX™ device, mimics many of the principles of the laparoscopic fundoplication, including that EsophyX™ reduces hiatal hernia, (...) and creates a gastroesophageal valve. However, EsophyX™ does not have the same issues with adverse effects that are seen with Nissen.
