GERD for a surgical resident can be organized into diagnosis, preoperative physiology, operative choices, technique, complications, and revision surgery.## GERD for the surgical resident

1. Core concept

GERD is reflux of gastric contents causing troublesome symptoms and/or mucosal injury. Surgical treatment restores the antireflux barrier at the gastroesophageal junction (GEJ), which normally depends on the intrinsic lower esophageal sphincter (LES), diaphragmatic crura, gastric sling fibers, intra-abdominal esophageal length, and angle of His. Hiatal hernia commonly impairs this system.
Typical symptoms
  • Heartburn
  • Regurgitation, often a stronger predictor of benefit from surgery than heartburn alone
  • Water brash
  • Chest/epigastric pain after excluding cardiac causes
  • Dysphagia, which requires investigation for stricture, malignancy, eosinophilic esophagitis, or a motility disorder
  • Extraesophageal symptoms: cough, hoarseness, throat clearing, globus, asthma-like symptoms. These have less predictable surgical response.

2. Who should be considered for antireflux surgery?

Operate on objectively proven GERD, not merely symptoms labelled "reflux."
Common indications:
  1. Chronic or PPI-refractory GERD with objective evidence of pathologic reflux.
  2. PPI-dependent patient who prefers surgery after informed counselling.
  3. Persistent, troublesome regurgitation despite optimized PPI therapy.
  4. GERD with a significant hiatal hernia, particularly when anatomical restoration is required.
  5. Complications of reflux:
    • Severe erosive esophagitis
    • Peptic stricture
    • Barrett esophagus, although surgery does not eliminate Barrett surveillance or cancer risk.
  6. Selected patients with medically treated reflux who have medication adverse effects, cost concerns, or poor adherence.
A response to PPI therapy tends to predict a better outcome after fundoplication. PPI nonresponse should prompt caution and re-evaluation for another diagnosis rather than automatic surgery.
The SAGES GERD guideline conditionally supports surgery over continued medical therapy for adults with chronic or refractory GERD.

3. Red flags and contraindication-type situations

Alarm features

Urgent endoscopy or appropriate workup is needed for:
  • Progressive dysphagia or odynophagia
  • GI bleeding or iron-deficiency anemia
  • Unintentional weight loss
  • Persistent vomiting
  • New symptoms at older age
  • Family history or concern for upper-GI malignancy

Do not rush to fundoplication when:

  • GERD is not objectively documented
  • Symptoms are functional heartburn, reflux hypersensitivity, rumination, supragastric belching, or untreated achalasia
  • Major dysmotility has not been characterized
  • Gastroparesis is the predominant cause of symptoms
  • The patient has isolated extraesophageal symptoms without supportive reflux testing

4. Preoperative workup: the resident's essential checklist

Most surgical candidates require these four studies.
TestWhy it matters
Upper endoscopy (EGD)Identify esophagitis, Barrett esophagus, peptic stricture, malignancy; assess hiatal hernia and GEJ anatomy.
Barium esophagram / upper-GI contrast studyDefines hiatal-hernia size and anatomy, short esophagus, stricture, obstruction, gross dysmotility, and postoperative anatomy. It does not establish GERD alone.
High-resolution manometry (HRM)Excludes achalasia and major motility disorders; evaluates peristalsis and helps tailor the wrap. It is not diagnostic of GERD.
Ambulatory reflux monitoringEstablishes abnormal acid exposure and symptom association, usually with pH or pH-impedance monitoring. Particularly important with normal EGD, atypical symptoms, or PPI nonresponse.
Practical rules
  • If there is no conclusive endoscopic reflux injury, obtain ambulatory reflux monitoring off PPI to prove GERD before primary antireflux surgery.
  • In a patient with already proven GERD but persistent symptoms on PPI, impedance-pH testing on PPI may identify ongoing reflux versus non-reflux symptoms.
  • HRM is mandatory before fundoplication to exclude achalasia and characterize motility.
  • Consider gastric emptying testing if there is prominent nausea, vomiting, early satiety, or bloating.
Sabiston describes ambulatory pH monitoring as the diagnostic gold standard and emphasizes EGD before antireflux surgery; barium study, pH testing, and manometry together clarify anatomy, reflux burden, and motility. Sabiston Textbook of Surgery, GERD section.

5. Standard operation: laparoscopic hiatal repair plus fundoplication

Key operative objectives

  1. Reduce the herniated stomach/GEJ.
  2. Completely mobilize the distal esophagus.
  3. Obtain approximately 2.5 to 3 cm of tension-free intra-abdominal esophagus.
  4. Preserve both vagus nerves.
  5. Excise mediastinal hernia sac when appropriate.
  6. Perform posterior crural closure without excessive narrowing.
  7. Construct a short, floppy, tension-free fundoplication around a bougie if used by the operating surgeon.
  8. Confirm that the wrap uses the fundus, not gastric body, and is not twisted.

Typical laparoscopic steps

  • Reverse Trendelenburg, liver retraction.
  • Divide gastrohepatic ligament and expose right crus.
  • Dissect hernia sac from mediastinum.
  • Circumferential mediastinal mobilization of esophagus while protecting anterior and posterior vagus.
  • Assess intra-abdominal esophageal length.
  • Posterior cruroplasty with nonabsorbable sutures. Add anterior sutures selectively.
  • Fundic mobilization as needed. Division of short gastrics is surgeon- and anatomy-dependent.
  • Create the selected wrap and anchor appropriately.

6. Which operation?

Nissen fundoplication

360-degree posterior wrap
  • Good reflux control.
  • Often selected with normal motility and prominent reflux/regurgitation.
  • Higher propensity for postoperative dysphagia and gas-bloat than a partial wrap in some patients.

Toupet fundoplication

270-degree posterior partial wrap
  • Frequently preferred in impaired peristalsis or when minimizing dysphagia is a major priority.
  • Provides reflux control while preserving easier venting and swallowing.

Dor fundoplication

Anterior partial wrap, more commonly associated with Heller myotomy than standard primary GERD surgery.

Magnetic sphincter augmentation

An option in selected patients with proven GERD and appropriate anatomy, provided the team has expertise. It is not a substitute for repairing a clinically relevant hiatal hernia.

Obesity and GERD

For patients with severe obesity, particularly BMI ≥35 kg/m² with metabolic indications, Roux-en-Y gastric bypass is often preferred over fundoplication because it treats both obesity and reflux. Sleeve gastrectomy can worsen or induce GERD.
Current SAGES guidance supports either partial or complete fundoplication based on patient priorities: complete wrap may favor maximal reflux control, whereas partial wrap may better prioritize minimizing dysphagia. SAGES recommendations

7. Hiatal hernia points

  • Type I sliding hernia: GEJ migrates above diaphragm. Most commonly associated with GERD.
  • Type II paraesophageal hernia: fundus herniates, GEJ remains below diaphragm.
  • Type III: both GEJ and stomach herniate.
  • Type IV: stomach plus another organ herniates.
In a symptomatic paraesophageal hernia, repair generally includes reduction, sac dissection, esophageal mobilization, cruroplasty, and usually a fundoplication if motility permits. The SAGES hiatal-hernia guideline addresses mesh, fundoplication, surveillance, and revisional choices.
Mesh: selective use only. It may reduce recurrence in some contexts, but synthetic mesh at the hiatus carries potentially severe erosion or stenosis risks. Know your unit's practice and the rationale for it.

8. Complications after fundoplication

Early

  • Pneumothorax/capnothorax
  • Bleeding
  • Esophageal or gastric perforation
  • Splenic injury
  • Vagal injury
  • Acute wrap obstruction or severe dysphagia

Late

  • Persistent dysphagia
  • Gas-bloat syndrome and inability to belch/vomit
  • Recurrent reflux
  • Slipped wrap
  • Wrap disruption
  • Intrathoracic migration/herniation of wrap
  • Tight cruroplasty or tight/twisted wrap
  • Delayed gastric emptying
Dysphagia approach
  1. Define timing and severity.
  2. EGD to assess lumen, wrap, and stricture.
  3. Barium swallow for anatomy and obstruction.
  4. HRM and pH-impedance when needed.
  5. Endoscopic dilation may help selected patients.
  6. Reoperate only after defining the anatomic/physiologic failure.
Sabiston reports a long-term reoperation rate after fundoplication of roughly 5% to 7%, commonly for recurrent reflux or persistent dysphagia. Sabiston Textbook of Surgery, GERD section.

9. Failed antireflux surgery: resident framework

Before redo surgery, answer four questions:
  1. Is reflux truly recurrent? Objective pH or pH-impedance evidence.
  2. What is the anatomy? EGD and contrast esophagram.
  3. Is there dysmotility or outflow obstruction? HRM.
  4. What failed?
    • Recurrent hiatal hernia
    • Slipped/migrated wrap
    • Disrupted wrap
    • Tight/twisted wrap
    • Incorrect initial diagnosis
    • Gastroparesis or functional symptoms
Redo surgery has higher risk of vagal, esophageal, gastric, and splenic injury. It should be done by surgeons experienced in foregut revision. In recurrent GERD with obesity, conversion to Roux-en-Y gastric bypass is often preferable to another fundoplication.

10. Oral-viva summary

Antireflux surgery is indicated for objectively proven, chronic or refractory GERD, especially with troublesome regurgitation, a significant hiatal hernia, or reflux complications. Before operating, I obtain EGD, contrast esophagram, high-resolution manometry, and ambulatory reflux testing when GERD is not already proven. The standard operation is laparoscopic hernia reduction, mediastinal esophageal mobilization, tension-free cruroplasty, and a tailored fundoplication. A complete Nissen favors reflux control, while a partial Toupet is often selected when limiting dysphagia is a priority. Postoperative dysphagia or recurrent symptoms require objective anatomical and physiological evaluation before considering redo surgery.
Recent-evidence note: Recent reviews include endoscopic and surgical antireflux procedures, but the PubMed results were either broad or focused on special populations. They do not replace individualized operative selection based on objective testing and local foregut expertise. Relevant recent systematic-review PMIDs: 41139639, 39145822.
