1 PeriOperative Concerns for Anti Reflux Procedure Patients Kevin Gillian, M.D., F.A.C.S. VHC Heartburn Center Director GERD word association Heartburn Chest pain Spicy food Tums Purple pills How big a problem is it? GERD stats Medical management PPI s H2 Blockers Promotility agents OTC 80% of pts relapse in 6 8 months following cessation of medical therapy 1

2 GERD stats 0.7% of adults are in the severe medically refractory group Equivalent to 39k in the D.C. DC Metro What other options do they have? Surgery (4 decades of experience) Endoscopic Therapy GERD stats Only 1/50 of the chronic GERD pts who fail medical therapy are treated surgically Why? Only 1% of pts under Rx for GERD are aware of a surgical option Only 50% of the primary care providers are aware of the surgical option Surgery and GERD Long term results in experienced hands show elimination of typical symptoms (> 90%) Results have improved with ih better patient selection EGD, UGI/BS, 24hr ph testing, manommetry Impedance technology is revolutionizing the work up 2

3 Acquired esophageal dysmotility Sllbufferny acid Lower Esophageal Sphincter (LES) dysfunction Poorly functioning sphincter muscle Gastroesophageal junction (GEJ) incompetent Delayed emptying of stomach Hiatal hernia Why do we reflux? Causes GERD? Deteriorated valve between stomach and esophagus allows acid to wash up into esophagus Hiatal Hernia and Elongation of PEM Hiatal Hernia Acid chamber Elongation of phrenoesophageal membrane Gastric tissue up into chest above diaphragm Small pouch Confirmed with CXR, barium series, EGD 65 80% of patients with chronic severe GERD have hh 2cm Symptoms Heartburn Burning or tightness behind sternum or top stomach (confused with angina heart attack like symptoms) Acid regurgitation Sour or bitter taste in throat or mouth Esp. after large, late meals Water brash Hot sensation in stomach Excess salivation Dysphagia and Odynophagia Difficulty swallowing or painful swallowing 3

12 Lap Nissen Durability Long term results of surgery for control of GERD are variable Symptom control often greater than 90% at 10 years in experienced hands Failures are often emphasized by gastroenterologist Disruption of the hiatal closure appears to be a major weak point in the repair Surgical Failure Rates Breakdown of Crural Repair Leading to Nissen Wrap Herniation Watson (1995)Brit J Surg % Cadiere(1996)Surg Endo Munro(1996)Surg Lap Endo Stein(1996)Am J Surg Perdikis(1997)Ann Surg Basso(2000) Surg Endo Champion(2001)Surg Endo Kamolz (2002) Surg Endo Frantzides(2002)Arch Surg 38 defects>8cm 22 Orringer(1973)J Thora Surg* 892 open surgery 14.5 Polypropylene Patch Basso Surgical Endoscopy 2000 First 67 pts 14.5 % Next 65 pt 0 % at 2yrs Sequential Study 12

American Hernia Society presentation 2008 Nissen with Mesh results No recurrent hernias in 109 pts No reflux symptoms after surgery No significant dysphagia No revisions or balloon dilatation No infections No chronic pain issues Gillian, G.K. American Hernia Society presentation

15 Summary of Mesh Utilization Historical Data Suggest that the failure rate of Nissen Fundoplication is largely due to hiatal disruption with secondary wrap migration Placement of a prosthetic mesh to reinforce the hiatal closure appears to improve recurrence rates just as it does in other types of hernia repair Summary of Mesh Utilization Evaluation of proactive mesh utilization in Nissen Fundoplication includes the mesh being used as well as fixation technique The placement of permanent/biologic mesh with the onlay technique is easily performed, safe and should impact the rate of hiatal hernia and symptom recurrence as time progresses Robotic Nissen Fundoplication DaVinci Platform Technically same steps and same risks Significant investment in staff training and resources 15

16 Robotic NissenVideo The EsophyX Approach Trans oral Surgery for GERD No incisions No scarring No incisional herniation Less potential for infection Does it work? Can you do it for everybody? GERD Treatment Options Benefits of EsophyX GEJ reconstructed PPIs reduced Can correct Esophagitis Hiatal Hernia fixed < 2cm Benefit Med/High Significant ph Normalization Improved Quality of Life Reduce/Eliminate reflux Adjustment possible Risk Low Challenges Large Hiatal Hernias Limitations of Rx Treat the symptoms not the anatomical cause Do not stop reflux Do not treat atypical symptoms 20 40% of patients are not happy with PPI medication* *Gallup Poll 2000 for AGA N=1000 American Journal of Gastroenterology 2003; vol. 98 Shaker et al 16

19 Effectiveness Conclusions EsophyX TIF was shown to be effective in treating chronic GERD as indicated by the significantly improved quality of life and reduced dependency on daily PPIs. The significant reduction in esophageal acid exposure, hiatal hernia and esophagitis as well as the significant increase in LES resting pressure supported the ability of EsophyX TIF to increase the antireflux competency of the gastroesophageal junction. The results at 12 and 24 mo supported a long term maintenance of the anatomical integrity of TIF valves. PACU considerations Minimally invasive surgery but Working in the mediastinum Dissection of Spleen Pleural tears possible with big hiatal hernias Esophageal perforation possible (TIF) Crepitus PACU Physical Exam Warning Signs Decreased Breath Sounds Tachycardia Chest Pain Dysphagia 19

20 Typical Surgical Recovery Overnight stay Clears on evening of surgery PPIs stopped on day of surgery Minimal narcotic usage after discharge Splat Diet for days Gradual Progression to regular diet in first month Summary Surgical repair of the structural defects that allow GERD to occur is effective. Full understanding di of the physiology involved and skill with all possible techniques available is necessary for complete patient care Thank you! 20
