11  Describe normal esophageal anatomy.  Understand the difference between water perfused manometry and solid state esophageal manometry.

12  Be able to properly identify and mark the following anatomic landmarks using high resolution manometry.  The upper esophageal sphincter (UES)  The esophageal body  The esophago-gastric junction (EGJ)  Be able to describe patient preparation for esophageal manometry.

13  Be able to describe how an esophageal motility catheter is placed.  Understand when to refer patients for esophageal manometry.  Know where to find resources to further your understanding of manometry.



16  Upper Esophageal Sphincter (UES)  Cervical esophagus  Cricopharyngeus  Inferior pharyngeal constrictor pharyngeal-muscles jpg

17  Esophageal body  The proximal 5% is striated muscle.  The middle 35%-40% is mixed (transition zone).  The distal 50%-60% is entirely smooth muscle. files/esophagus-anatomy.jpg

18  Muscular composition  Outer layer (longitudinal).  Inner layer (circular). ▪ more precisely helical muscle.

19  Clinical Correlation:  Presbyesophagus also known as tertiary contractions her-%C3%96sophagus.jpg

20  There are three major contributors to the EGJ high pressure zone.  1. The LES  2. The crural diaphragm  3. The muscular architecture of the gastric cardia

21 Understand the difference between water perfused manometry and solid state esophageal manometry

22  Water Perfusion Manometry (Conventional).  Every 5 cm  Solid State Manometry (High Resolution, 3D).  Every 1 cm visitors/education/PublishingImages/G -L/EsophManometry-1.jpg

23  8 channels, 4 are located 5 cm from the tip of the catheter with 4 other more proximal sensors spaced 5 cm apart.  3.9 mm diameter.


25  All sensors are truly circumferential.  36 channels spaced 1 cm apart 12 pressure sensing points at each channel (432 data points).  Small diameter 2.75 mm. Source:

26  Magenta end of color spectrum (hot colors) = highest pressure.  Blue end of color spectrum (cool colors) = lowest pressure.



29 CONVENTIONAL MANOMETRY  Need to move catheter for LES in most systems  Water-perfusion systems are multicomponent and cumbersome  Low fidelity  Waveforms only  LES measurements complex; some use sleeves, others need station pull-through technique  Hard to find hiatal hernias  Water-perfused catheters are stiff and more uncomfortable  Tests take longer  Large gaps between channels (5 cm) HIGH RESOLUTION MANOMETRY  Catheter stays in one position  Solid state systems are relatively simple and less cumbersome  High fidelity  Color contour  No need for pull through: software creates an electronic sleeve for LES determination  Hiatal hernias are easily identified  Solid state catheters are soft and more comfortable  Procedure takes less time  Array of 36 channels straddle the entire esophagus, sees the entire organ



32  How do you describe esophageal manometry to a patient?  During esophageal manometry, a thin, pressure-sensitive, flexible tube is passed through your nose and into your stomach.  When the tube is in your esophagus, you will be asked to swallow. The pressure of the muscle contractions will be measured along the length of your esophagus.  The tube is removed after the test is completed. The test takes about 1 hour.

33  How do you tell patients to prepare for a manometry?  Patients should not have anything to eat or drink for 4-6 hours before the test (varies by center).  There is no need for bowel preparation.  Take all prescribed medications as usual. ▪ This includes anticoagulants, aspirin, and NSAIDs, acid suppressive therapy.

34  How will the test feel?  Typically, the test is not uncomfortable.  Some patients may experience a gagging sensation when the tube is being placed.


36  Before bringing the patient into the room an RN performs a focused H&P and chart review. ▪ Indication (dysphagia, chest pain, pre-operative evaluation, etc.) ▪ Allergies (assure the patient isn’t allergic to lidocaine) ▪ If they are use sterile lubricant jelly ▪ Pertinent past surgeries (Nasal, esophageal, bariatric surgery etc.)  Make sure the patient did not eat or drink anything for 4 to 6 hours prior to test (this varies by center).

37  The patient is brought into the procedure room.  A gown is placed over their upper body and they sit on the edge of a gurney.  The patient occludes each nostril and sniffs to determine if their right or left nostril is more patent /png/assess_patency_of_nostrils png

38  The nostril is numbed with 2% lidocaine jelly using a 6-inch cotton tip applicator.  The manometric catheter is lubricated with 2% lidocaine.

39  The patient brings their chin down to their chest.  The catheter is advanced through the medicated nostril into the esophagus while the patient swallows. media/medical/hw/h _001.jpg

40  The manometric catheter is advanced until it crosses the lower esophageal sphincter and its distal tip is in the stomach.  The catheter is secured in place with tape.  The patient then lies supine on a gurney. visitors/education/PublishingImages/G -L/EsophManometry-1.jpg

41  5 ml of water (or saline) is placed into the patient’s mouth using a syringe.  The patient holds the liquid in their mouth then swallows once.  30 seconds later this is repeated.  10 wet swallows are performed.  The catheter is removed.





46  Dysphagia.  Non-cardiac chest pain.  Placement of intraluminal devices (e.g. pH probes).  Preoperative assessment of patients being considered for anti-reflux surgery and bariatric surgery.  Detecting esophageal motor abnormalities associated with systemic diseases (e.g. connective tissue diseases). American Gastroenterological Association Patient Care Committee on May 15, 1994

47  The first step is to distinguish between oropharyngeal dysphagia and esophageal dysphagia.  Oropharyngeal dysphagia:  Arises from dysfunction of the pharynx and upper esophageal sphincter.  Esophageal dysphagia:  Arises from disorders of the esophageal body and lower esophageal sphincter.

48 OROPHARYNGEAL  Have difficulty initiating a swallow.  Localize symptoms to the cervical region.  Frequently associated with coughing, choking, nasal regurgitation, and dysphonia. ESOPHAGEAL  Have difficulty swallowing several seconds after initiating a swallow.  Localize symptoms to the suprasternal notch or behind the sternum.  May be associated with a history of food impaction or food “sticking” in the chest.


50  Do you have problems initiating a swallow or do you feel food getting stuck a few seconds after swallowing?  Do you cough or choke or is food coming back through your nose after swallowing?  Do you have problem swallowing solids, liquids, or both?  How long have you had problems swallowing and have your symptoms progressed, remained stable, or are they intermittent?

51  Could you point to where you feel food is getting stuck?  What medications are you using now?  potassium chloride  alendronate  ferrous sulfate  quinidine  ascorbic acid  tetracycline  aspirin  NSAIDs

52  Upper Endoscopy:  Patients with suspected esophageal dysphagia should be referred for an upper endoscopy as the initial test.  Structural assessment.  Has the advantage that biopsies can be obtained and intervention performed. ded/images/all/UpperEndoscopy.jpg

53  Barium swallow:  This is a good second test following a negative upper endoscopy if a mechanical obstruction is still suspected. ▪ External compression. ▪ B rings (Schatzki ring) can be missed. ▪ Zenker’s diverticulum ▪ Cricopharyngeal bar  Structural and functional assessment.  Can assess the UES and pharynx more reliably than upper endoscopy. mages/media/medical/hw/h jpg

54  Esophageal Manometry:  Motility testing should be performed in patients with dysphagia in whom upper endoscopy is unrevealing and/or an esophageal motility disorder is suspected.  Functional assessment. _6.jpg

55  47 year old woman with 2 years progressive dysphagia to solids and liquids. After meals she has a sensation of fullness in her chest. She often drinks water to make solid food pass.  A recent EGD was normal thus she was referred for esophageal manometry.

56 Norma l 1.Mean IRP > upper limits of normal (incomplete LES relaxation) 2.Absence of esophageal peristalsis (note: specifics vary for type I, II, and III achalasia)

57  The patient underwent pneumatic dilation of her LES to 30 mm with marked improvement in her symptoms.  Therapeutic options  Heller myotomy  Pneumatic dilation  Botox injection into the LES  POEM (Per Oral Endoscopic Myotomy)

58  An esophageal source of chest pain should be considered only after cardiopulmonary factors have been carefully investigated. ?Ref=t&RefId=gastrointestinal_disorders/esophageal_and_swallowing_ disorders/gastroesophageal_reflux_disease_gerd&Plugin=WMP&Speed =256&ItemId=v891242

59  A patient should first undergo an upper endoscopy and exclusion of GERD.  GERD is the most common cause of non- cardiac chest pain.  GERD is much more common than an esophageal motility disorder. content/uploads/2012/10/Chest-Pain-After-Eating.jpg

60  A 84 year old male complains of severe chest pain which onsets during meals.  EGD, CT abd/pelvis, barium esophagram, and 24 hour ph study are all normal. A cardiac work-up and which includes a nuclear perfusion test is normal. He is told by an ER physician that his symptoms are stress induced and “in his head”.  The patient is referred by his PCP for esophageal manometry.

61 1.DCI > 8,000 mmHg-cm-s (hypercontractile esophagus) 2.Normal mean IRP (the EGJ relaxes normally)

62  He initially is treated with diltiazem which causes intolerable hypotension and orthostasis. This medication is stopped and he undergoes EGD with botox injection into the LES with complete resolution of his symptoms.  Therapy  Rule out EGJ outflow obstruction causing reactive hypercontractile peristalsis  Treat GERD if present  Calcium Channel blockers (Diltiazem)  Nitrates (Isosorbide dinitrate)  Sildenafil  Botox injection into the LES

63  The most important role of esophageal manometry in patients with GERD has traditionally been for evaluation prior to antireflux surgery.

64 Why is esophageal manometry done prior to esophageal or gastric surgery?

65  Manometry may lead to a modification of the surgical approach.

66  Esopahgeal manometry may lead to an alternative diagnosis such as scleroderma or achalasia. 20-f4.jpg

67  Evaluation of post operative symptoms.  The best way to determine if a surgery is causal of a manometric abnormality is comparison of a patient’s pre-operative manometry study to their post-operative manometry study.

68  42 year old woman with long standing heartburn which has had relatively little improvement despite trials of omeprazole, esomeprazole, and dexlansoprazole.  Upper endoscopy reveals a small sliding hiatal hernia with LA class A erosive esophagitis.  She is referred to a surgeon for consideration of fundoplication. Her surgeon orders pre- operative esophageal manometry and pH testing.

69 1.DCI > 8,000 mmHg-cm-s (hypercontractile esophagus) 2.Normal mean IRP (the EGJ relaxes normally)

70  The patient was treated for a hypercontractile esophageal disorder with a calcium channel blocker with a significant reduction in symptoms.

71  A 49 year old woman with GERD complains of severe heartburn. This improves with twice daily PPI therapy and lifestyle modification, however severe nocturnal symptoms persist.  EGD reveals a hiatal hernia and LA class C esophagitis despite compliance with BID PPI.  She is referred to a surgeon for consideration of fundoplication. Her surgeon orders pre- operative esophageal manometry and pH testing.

72 1. Normal mean IRP (normal EGJ relaxation) 2. > 20% of swallows with large (> 5 cm) breaks in the 20 mmHg isobaric contour. Norma l

73  Ambulatory reflux monitoring revealed an 12% incidence of acid reflux despite compliance with PPI therapy with an elevated DeMeester score.  The patient underwent Toupet fundoplication. Her symptom of heartburn has resolved and she is now off PPI therapy.  Her only concern post-operatively bloating and an inability to belch.
