Anatomy
• Mucosa, submucosa, muscularis
propria, and adventitia
• Lack serosa vs. other GI tract
• Mucosa innermost (4 layers)
– contains squamous
epithelium
Muscularis Propria
•Continuation of inferior constrictor of the
pharynx
•Two muscle bundles
•inner circular
•outer longitudinal
•Striated upper 1/3
-vagus and its recurrent
laryngeal branches
•Smooth lower 2/3
-visceral nerve plexus derived
from neural crest cells
•Left vagus anterior-liver/biliary tree
•Right vagus posterior-celiac plexus
Esophageal Arteries
Upper-Inferior Thyroid Artery
Lower-Left Gastric and Inferior Phrenic arteries, bronchial arteries
and 4-6 aortic branches
Esophageal Veins
Esophageal Lyphatics
Lymphatics: upper 2/3 cephalad, lower 1/3 caudad
Anatomy
Anatomic Areas of Narrowing
• Cricopharyngeal muscle
• Left mainstem bronchus
and aortic arch
• Diaphragm
Anatomic Areas of Narrowing
UES
• 15 cm from incisors
• Cricophayrngeus
muscle, recurrent
laryngeal nerve
• Site of perforation is
cricopharyngeus
muscle (with EGD),
aspiration if UES fail
• 40 cm from incisors
• No anatomic landmarks
LES
– rise in pressure when transducer
is pulled from the stomach
• Increased Pressure: Alphaadrenergics, BBs, gastrin,
motilin, antacids,
cholinergics, metoclopramide
• Decreased Pressure: Alpha
blockers, Beta andrenergics,
CCK, estrogen, glucagon,
progesterone, somatostatin,
secretin, barbiturates, CCBs,
caffeine, diazepam,
dopamine, meperidine,
ethanol, coffee, fat
LES
• High pressure except:
1. passage of food into the stomach
2. when fundus is distended with gas, LES
eliminated to allow venting of the gas
• Loss of the normal high-pressure zone
leads to GERD (transient vs
permanent)
Gastroesophageal Reflux
Disease
• 1/3 Western population
experience symptoms at
least once a month
• 4-7% daily
• Most patients with mild
symptoms carry out selfmedication
• The prevalence and
severity of GERD is
increasing
Typical GERD Symptoms
•
Heartburn
– substernal burning or chest pain
– worse with spicy foods, tomato sauce, citrus
juices, chocolate, coffee, and alcohol
– 1 to 2 hours after eating, often at night, relieved by
antacids and OTC H2 blockers
•
Regurgitation
– sensation that fluid or food is returning into the
esophagus
– worse at night or when lying down after a meal
•
Dysphagia
– up to 40% of pts with GERD have sensation of
food hanging up in the lower esophagus-esophageal dysphagia
– typically limited to only solid food, with normal
passage of liquids, suggesting mechanical
disorder
– develops slowly enough that the patient may
adjust eating habits unknowingly
Atypical GERD Symptoms
• Cough, asthma, hoarseness,
and noncardiac chest pain
• primary complaint in 20-25%
• more difficult to prove a causeand-effect relationship
• trial of high-dose PPIs is
helpful
• make sure patient doesn’t
have another cause for pain
Pathophysiology of GERD
•
Fundic distention because of overeating
• LES is taken up by the expanding fundus, exposing the squamous
epithelium/LES to gastric juice
– Worsened by delayed gastric emptying with high-fat diet and hiatal hernia
•
Compensated with increased swallowing
– Saliva bathe the injured mucosa and alleviate the discomfort
= aerophagia, bloating, repetitive belching
• More distension leads to further exposure and repetitive injury to the
terminal squamous epithelium leading to inflammation
•
continued epigastic pain and possibly epithelial columnarization
•
Extension of the inflammatory process into
the muscularis propria
– leading to a permanently defective sphincter
Diagnosis of GERD
•
Based on symptoms alone?
– Correct in only 2/3 of patients
– these symptoms are not specific for GE
reflux
•
achalasia, diffuse spasm, esophageal carcinoma,
pyloric stenosis, cholelithiasis, gastritis, gastric or
duodenal ulcer, and coronary artery disease
– need objective diagnosis before the
decision is made for surgical treatment
Diagnosis of GERD
•
First episode
– Initial therapy with H2 blockers or PPI for 12 weeks
•
Failure of H2 blockers or PPI to control the symptoms suggests that either
the diagnosis is incorrect or the patient has severe disease
EGD
– Opportunity for assessing the severity of mucosal damage
24-hour pH and bilirubin monitoring
– Measurement degree and pattern of esophageal exposure to gastric
and duodenal juice
Manometry
– Assess the status and function of the LES and esophageal body
•
•
•
•
These studies identify features that predict a poor response to medical
therapy, frequent relapses, and the development of complications
Complications of GERD
• Mucosal complications-esophagitis and stricture
• Extraesophageal or Respiratory
complications, such as laryngitis, recurrent
pneumonia, and progressive pulmonary fibrosis
• Reflux (aspiration) vs reflex (vagal
bronchoconstriction)
• Metaplastic and Neoplastic complications,
Barrett's and esophageal adenocarcinoma
• Prevalence/severity of complications related to the
degree of loss of the GE barrier and content of refluxed
gastric juice, not symptoms
Barrett’s Esophagus
• Squamous epithelium metaplasia  columnar epithelium
• 7-10% of patients with GERD
• Normally, the SCJ should coincide with the GEJ (linear gastric
mucosal folds)
• Presence of any columnar mucosa extending at least 3 cm into the
esophagus (goblet cells)=Barrett’s
– predisposed to malignant degeneration
• Increased risk of adenocarcinoma x50
Classification and Management
of Barrett’s Esophagus with
Dysplasia
• Indefinite for Dysplasia: Aggressive
antireflux therapy (60 mg PPI per day) and
repeated biopsy in 3 months
• Low Grade: Aggressive antireflux therapy
vs. surgical treatment
• High Grade-Esophagectomy and PPI
Dysphagia
• Difficulty in transferring a food from the mouth to the
stomach
• Regurgitation, chest pain, heartburn, and coughing or
choking spells
• Oropharyngeal
– functional disturbance in the swallowing mechanism
• Esophageal
– mechanical obstruction or esophageal motility disorder
Dysphagia
• Evaluation of a patient with dysphagia must be
performed in a systematic manner
– Barium swallow
• Additional diagnostic tests
– EGD, manometry, 24-hour pH study, and possibley
bronchoscopy and endoscopic ultrasonography
(EUS).
– Diagnostic imaging by CT and PET in assessing
patients with esophageal cancer
Oropharyngeal Dysphagia
– inability to chew food, drooling, coughing during a meal, and
nasal regurgitation of solids or liquids
– dysphagia within 1 second of swallowing
• The common causes can be grouped into three broad
categories:
1) generalized systemic conditions: CVA, Myasthenia gravis
2) intrinsic functional disturbances: Zenker's diverticulum
3) fixed mechanical obstruction: Neoplasm, webs, previous
surgical treatment, previous radiation therapy
Esophageal Dysphagia
Dysphagia with solids?
=Mechanical Obstruction
• Intermittent? Esophageal Ring or Esophagitis
• Progressive with GERD? Peptic Stricture
• Progressive with weight loss and anorexia? Esophageal
Cancer
Dysphagia for both liquids and solids?
=Motility Disorder
• Intermittent? Spasm (DES)
• Progressive with GERD? Scleroderma
• Progressive? Achalasia
Schatzki's Ring
• symmetrical narrowing at SCJ,
small hiatal hernia
• correlation with GERD
• barium swallow and
esophagoscopy to confirm
• Asymptomatic? no specific
treatment is needed
• Definitive treatment? dilatation
of the ring with medical therapy
for GERD. If refractory,
dilatation plus antireflux
surgery
Peptic Stricture
• H/o GERD
– worsening dysphagia for years without weight loss
• End stage of ulcerative esophagitis, healing ulcer causes annular
fibrosis
• Dx: barium swallow followed by upper GI endoscopy
• greater length and more tapered than Schatzki’s
Esophageal Webs
• localized narrowing of the esophagus caused by intraluminal
extension of the mucosa and part of the submucosa
• congenital or acquired (mc), usually secondary to conditions such as
iron deficiency anemia/Plummer-Vinson syndrome and
ulcerative colitis.
• Tx: endoscopic dilatation
Achalasia
• Dysphagia for liquids and solids
and possibly weight loss.
• Barium swallow shows absent
peristalsis and a dilated
esophagus, possibly tapered
narrowing in distal
esophagus=bird's beak
• Achalasia risk factor for
squamous cell cancer
• Tx: Pneumatic dilatation or
surgery
Diffuse esophageal spasm
• unknown etiology
• Nonprogressive dysphagia with
solids and liquids and
nonexertional chest pain that
responds to nitroglycerin
• corkscrew on barium
• The diagnosis by manometry
– periodic occurrence of
simultaneous high-amplitude
contractions with intervening
periods of normal peristalsis.
• Tx: r/o CAD, then medical
management of reassurance,
nitrates, and CCBs
• Botulinum toxin injection, surgery
does not have an established role
Nutcracker Esophagus
• unknown etiology
• women>men
• Manometry: peristaltic waves with
significantly elevated amplitude (> 180 mm
Hg).
• Treatment is primarily medical
Hypertensive LES
• unknown etiology
• can occur alone or in association with
achalasia, nutcracker esophagus, or DES
• Manometry-LES pressure over 45 mm Hg
• Tx: primarily medical, but balloon dilatation
is done
Esophageal Diverticula
• < 5% of all cases of dysphagia.
• False diverticula (pulsion) include only the
mucosal layer
– underlying motor dysfunction
• True diverticula (traction) include all layers of
the esophageal wall
– inflammatory process
• Esophageal diverticula may also be classified
into three categories on the basis of the
anatomic level at which they occur
Pharyngoesophageal/Zenker’s
Diverticula
• MC
• from muscle incoordination
that leads to herniation of the
mucosa in prox esophagus
• Dysphagia mc symptom,
halitosis, regurgitation, throat
discomfort, palpable neck
mass, recurrent aspiration
pneumonia
• The best initial diagnostic
tool is a barium swallow
• perforation in EGD
Midesophageal diverticula
• True traction diverticula
• Caused by periesophageal inflammation in
granulomatous inflammation of the subcarinal lymph
nodes from TB or fungal infection
• Frequently asymptomatic and are often found
incidentally
• Dysphagia does occur but is a rare symptom
Epiphrenic diverticula
• Acquired pulsion
diverticula of distal
esophagus
• Associated with other
esophageal motor
disorders (achalasia,
DES, and hypertensive
LES) but can occur alone
• Absent or mild
symptoms?
– Conservative
management is
appropriate
• Significant dysphagia?
– Surgical management
Chemical Ingestion
• Alkali household cleaning agents
• Most occur accidentally in children,
but suicide in adults
• Magnitude and site of the injury?
– Related to the length of the
contact time
– Injury at any level, MC is distal
esophagaus
• lead to submucosal scar
formationstricture and dysphagia
• Endoscopic exam is first step
• A barium swallow should be done in
the first month after injury to detect
any stricture and then serial swallows
Hiatal Hernia
I-Sliding, dilation of hiatus, most commonly associated with GERD
-most with reflux have sliding, most with sliding don’t have reflux
II-Paraesophageal, defect in diaphragm alongside esophagus with normal
GE junction
--chest pain, dysphagia, early satiety
III-Combined I and II
IV-entire stomach in chest plus another organ (colon, spleen)
Laparoscopic Antireflux Procedure
• Most commonly performed procedure is a
fundoplication
• Nissen Fundoplication: 360 degree
fundoplication
• Laparoscopic approach reduces
postoperative pain and shortens length of
hospital stay
– Rapid increase in surgical treatment of GERD
• Preoperatively
– h/o recurrent heartburn enough to clinically establish
GERD and initiate empiric medical therapy
– Those patients with recurrent or refractory symptoms
require further evaluation prior to surgery
• Endoscopy
– Evaluate for Barrett’s Esophagus
• Manometry
– Evaluate for other causes of esophageal dysmotility
• 24 hour pH
– May be helpful, especially in those patients with atypical GERD
symptoms or other GI comorbidities
• Indication
– Failure of maximal medical therapy
• Short 2 month trial
– Failure of lifestyle modification
• Weight loss
• Alteration in diet (avoid chocolate, peppermint, fat, onions,
garlic, alcohol, caffeine, nicotine)
• Avoid food 2-3 hours prior to sleep
• Elevation of head of bed 6 – 10 inches
• Limit potentially precipitating activities (bending over or
strenuous exercise)
– Complications of GERD
• Esophagitis, stricture, recurrent aspiration or pneumonia,
Barrett’s esophagus
– Associated with paraesophageal hernia
– Intolerance to medical therapy or patient desiring
discontinueation of medical therapy
• Contraindication
– Absolute
• Inability to tolerate general anesthetic or laparoscopy
• Uncorrectable coagulopathy
– Relative
•

•
Previous upper abdominal surgery
Morbid obesity
Severe esophagitis with or without stricture
Small-body habitus
Short esophagus
– Particularly for fundoplications
• Paraesophageal hiatal hernia
• Basic tenets of antireflux surgery
– Restoration of an effective LES
– Creation of a gastroesophageal valve
– Mechanical effects of a fundoplication
• Fundus exhibits a physiologic phenomenon of
receptive relaxation
– Decreased tone of the gastric fundic smooth muscle in
association with swallowing-induced relaxation of the
LES
Laparoscopic Port Placement
Belsey Mark IV Repair
• Transthoracic repair to control GERD
• Typically performed through a left thoracotomy
– May be performed thoracoscopically
• McKernan and Champion modified Belsey
• Distal esophagus and proximal stomach are
mobilized and ddelivered through the esophageal
hiatus
• Anterior 270 degree plication of the fundus is
performed onto the esophagus
• The fundoplication is buttressed by the
diaphragmatic crura
Nissen Fundoplication
• 360 degree wrap around esophagus
–
–
–
–
Circumferentially dissecting the distal esophagus
Mobilizing the gastric fundus
Plicating the fundus around the lower esophagus
Creating a high-pressure zone
• Increases the resting tone of the sphincter mechanism
• Improves its response to elevated intragastric pressure
– Fundoplication varied from 3 – 6 cm and included
the esophageal wall in the fundoplication
– No division of the short gastric vessels
• Rossetti-Hell modification
– Included wrapping the anterior portion of the
fundus around the esophagus
– No division of the short gastric vessels
– Minimal moblization of the upper stomach
– Created a 3 – 6 cm 360 degree fundoplication
• Short, floppy Nissen
– Most common modification used today
– The short gastric vessels are divided
– Full fundic mobilization and the lateral border
of the fundus is wrapped around the
esophagus
• Sutured to the medial edge of the medial fundus
– Short fundoplication, < 2.5 cm
– Fashioned over a 50 to 60F bougie
• Complication of total fundoplication
– Dysphagia
– Inability to belch
– Gas-bloat syndrome
– Hypercontinent
Partial Fundoplication
• Indication
– Poor esophageal clearance because of
esophageal motility abnormality
– Severe aerophagia, daytime reflux associated
with belching
– Insufficient gastric fundus
• Previous gastrectomy
• Tubular stomach
– Psychological inability to tolerate side effects of
fundoplication
– Association with Heller myotomy for achalasia
• Dor Fundoplication
– 180 to 200 degree anterior wrap
– Used in association with Heller esophagomyotomy for
achalasia
• Watson fundoplication
– Plication of the fundus along the left anterolateral
border of the esophagus
• More physiologic
• 120 degree anterolateral wrap
• Toupet fundoplication
– Most common partial fundoplication laparoscopically
– 270 degree posterior wrap
– Fundus pulled posterior to esophagus with suture of
leading edge to right anterior aspect of the esophagus
Hill Repair
• Indication
– Reflux symptoms refractory to medical
management
– Younger patients asymptomatic but requiring
high-dose medication
• Avoid lifetime dependence on medication
– Chronic esophagitis, inflammatory shortening
of the esophagus and paraesophageal hernia
• Advantage
– Posterior fixation of GE junction
• Prevent recurrent herniation and improve distal esophageal
clearance by improving longitudinal function
– Distal high-pressure zone can be calibrated; avoiding
late dysphagia
– Does not require a gastroplasty with a short
esophagus
– Can be preformed in patients that have undergone a
gastrectomy
– Shorter hospital stay and faster recovery compared to
open procedure
• Contraindication
– Morbid obesity
– Failed previous antireflux operation
– Prior extensive upper abdominal surgery
• Pre-operative
– Endoscopy
• Evaluate for Barrett’s esophagus
• Evaluate and grade gastroesophageal valve
– Grade I: normal musculomucosal valve
– Grade II: valve that is slightly less defined and shorter than
Grade I
– Grade III: valve is poorly defined; stays open, allows reflux
and is associated with a hiatal hernia
– Grade IV: no definition to the musculomucosal fold; stays
open constantly and is associated with a hiatal hernia
– Manometry
• Evaluate for Motility disorder
– 24 hour pH study
• Evaluate and confirm the diagnosis of GERD
• Hill Repair
– A 43F bougie is passed through the GE junction
along with a manometry probe during the repair.
– Intraoperative manometry is performed to calibrate
the GE junction
• Reconstructed LES is approximately 3 to 4 cm
• Peak pressure during pull through > 45 mm Hg than sutures
are loosened
• Peak pressure < 20 mm Hg, sutures are tightened
– Following calibration; sutures are fixed permanently
over a bougie
– Fundus is secured to the rim of the diaphragm
• Accentuate the angle of His and elongate the
gastroesophageal flap valve
Failed Fundoplication
• Learning curve requires 30 to 50 operations
– Decreasing operative time
– Diminishing rates of complications
• Dysphagia
– Excessively tight closure of the esophageal hiatus
• Tight wrap or tension on the wrap
• Sliding hiatal hernia with wrap in abdomen
• Migration of the wrap into the mediastinum
– Most common complication
– New-onset substernal or epigastric pain
• Slipped Nissen
– Secondary to disruption or migration of the wrap onto the
stomach

-GERD is seen in up to 72% of obese persons
-GERD is usually only one of many co-morbidities in obese: OSA, HTN, DM,
HL
-Fundoplication directed solely at treating GERD does not adequately address
the underlying cause, nor does it do anything to help with the other comorbid conditions
-A bariatric procedure allows for weight loss and improvement or resolution of
other associated

-All candidates for a laparoscopic Nissen fundoplication should undergo a
preoperative evaluation that includes symptomatic evaluation, barium swallow,
endoscopy, esophageal manometry, and ambulatory pH monitoring.
-Ambulatory pH monitoring is the most reliable test for the diagnosis of GERD;
it has a sensitivity and specificity of about 92%.
A 60 year-old otherwise healthy man has symptomatic GERD that
has not responded to medical therapy, including PPIs.
Esophagoscopy shows moderately severe esophagitis. Multiple
biopsies of the esophageal mucosa in the area of esophagitis show
columnar epithelium replacing the normal squamous epithelium. As
the patient’s treatment is being planned, a biopsy report shows highgrade dysplasia.
Treatment should be:
A. Continued medical treatment with yearly esophagoscopy and biopsies
B. Laparoscopic Nissen fundoplication
C. Photodynamic therapy
D. Esophagectomy

Four years ago, a 47 year-old woman had a laparoscopic
fundoplication. It failed after three years and she had
severe, recurrent gastroesophageal symptoms. Through a
celiotomy incision, the surgeon performed a redofundoplication with a 360-degree, 2 cm wrap around a 56
Fr dilator. For the past three months she has had severe
early satiety, postprandial epigastric pain, and weight loss.
The most likely cause of these symptoms is:
A. The wrap is too tight
B. The wrap is too loose
C. Vagal injury
D. Irritable bowel syndrome
E. Esophageal motor disorder

Distal esophageal web, or Schatzki’s ring, is an annular constriction of the
esophagus that indicates the presence of a sliding hiatal hernia.
Plummer-Vinson syndrome is cervical esophageal dysphagia associated
with iron-deficiency anemia. The condition is commonly associated with
cervical esophageal webs.
Plummer-Vinson syndrome is considered a premalignant condition; 10% of
patients develop SCC of hypopharynx, oral cavity, or esophagus.
