A Heller myotomy is the surgical treatment for achalasia, an esophageal motility disorder in which the lower esophageal sphincter (LES) fails to relax and the body of the esophagus loses its normal coordinated peristalsis, causing food and liquid to back up rather than pass into the stomach (Savarino et al., Nature Reviews Disease Primers, 2022). The operation is named for Ernest Heller, who first described surgical division of the lower esophageal and upper gastric muscle in 1913; since 1991–1992 it has been performed laparoscopically, which allows better visualization, a shorter operation, and faster recovery than the older open approach (Midya et al., Cochrane Database of Systematic Reviews, 2022; Blonski et al., Dysphagia, 2023).

The procedure has two essential components: a myotomy — dividing the circular and longitudinal muscle fibers across the LES, extending at least 4–6 cm up the esophagus and 2–3 cm onto the stomach to eliminate the obstructing gastric sling fibers — and a partial fundoplication (an anterior Dor or posterior Toupet wrap) to rebuild an antireflux barrier, because cutting the LES otherwise leaves patients prone to severe gastroesophageal reflux (Blonski et al., Dysphagia, 2023; Savarino et al., Nature Reviews Disease Primers, 2022). Laparoscopic Heller myotomy with partial fundoplication is one of the three definitive, durable treatments for achalasia — alongside pneumatic dilation and peroral endoscopic myotomy (POEM) — and remains the surgical standard of care, with clinical success (improvement of dysphagia) in roughly 87–90% of patients (Khashab et al., ASGE Guideline, 2020; Scaffidi et al., Cochrane Database of Systematic Reviews, 2025).

‍

Achalasia obstructs the esophagus at a single point — the non-relaxing lower esophageal sphincter — so swallowed food cannot pass into the stomach (Savarino et al., Nature Reviews Disease Primers, 2022). The Heller myotomy mechanically relieves that obstruction by cutting through the muscular ring of the LES (and the gastric sling fibers just below it), lowering the resistance to flow at the esophagogastric junction so gravity and residual esophageal function can empty the esophagus (Werner et al., New England Journal of Medicine, 2019). Because the surgeon divides only the muscle layers and leaves the inner mucosal lining intact, the esophagus is "released" without being opened (Midya et al., Cochrane Database of Systematic Reviews, 2022).

Dividing the LES, however, destroys the body's natural antireflux barrier, which is why a partial fundoplication is added routinely: a randomized trial found objective reflux in 48% of patients after myotomy alone versus 9% when a partial fundoplication was added, with no loss of dysphagia relief as long as the wrap is partial rather than complete (Savarino et al., Nature Reviews Disease Primers, 2022). The result is durable relief of swallowing difficulty while minimizing the reflux that would otherwise follow (Tassi et al., Annals of Surgery, 2023).

‍

• Durable, high-rate relief of dysphagia — clinical success (dysphagia improvement) in roughly 87.7% of patients across a meta-analysis of 5,834 patients, with predicted improvement of ~91% at 12 months and ~90% at 24 months (Khashab et al., ASGE Guideline, 2020).

• Proven long-term durability — in a prospective single-center series, satisfactory outcomes reached ~96% for videolaparoscopic Heller-Dor; 10-year dysphagia-free survival is about 80%, with Eckardt score ≤3 maintained in roughly three-quarters of patients at 10 years (Tassi et al., Annals of Surgery, 2023; Fukushima et al., Surgical Endoscopy, 2021).

• Built-in reflux protection — the added partial fundoplication markedly reduces post-myotomy GERD compared with myotomy alone (Savarino et al., Nature Reviews Disease Primers, 2022).

• Remarkably safe — operative mortality is under 0.1%, with low overall morbidity in experienced hands (Blonski et al., Dysphagia, 2023).

• Minimally invasive recovery — laparoscopic/robotic technique means small incisions, a short hospital stay (often ~1–3 days), and a relatively quick return to activity (Aaron et al., ACS Gastrointestinal Surgical Emergencies, 2021).

• Effective across subtypes — type I and type II achalasia respond equally well; type III responds less well than to POEM but better than to pneumatic dilation (Blonski et al., Dysphagia, 2023).

‍

The ideal candidate has manometrically confirmed achalasia (or a related LES outflow obstruction) with troublesome dysphagia, who is medically fit to tolerate general anesthesia and pneumoperitoneum (Savarino et al., Nature Reviews Disease Primers, 2022; Mustian & Wong, Abdominal Radiology, 2025). Favorable features include:

• Type I or type II achalasia, which respond excellently to Heller myotomy (type III is often better served by POEM, which allows a longer myotomy) (Blonski et al., Dysphagia, 2023).

• Younger patients, higher LES pressure (>30 mmHg), and a straight, non-tortuous esophagus — all predictors of surgical success (Blonski et al., Dysphagia, 2023).

• Fitness for laparoscopy — the main contraindications are medical comorbidities that prohibit pneumoperitoneum (Mustian & Wong, Abdominal Radiology, 2025).

• Advanced/sigmoid (megaesophagus) disease can still benefit — Heller-Dor provides good results in most patients even with an esophagus >6 cm or a sigmoid shape, though end-stage disease may ultimately require esophagectomy (Fisichella, JOMI, 2024; Savarino et al., Nature Reviews Disease Primers, 2022).

Patients who are poor surgical candidates may instead be offered pneumatic dilation, POEM, or — as a temporizing measure — endoscopic botulinum toxin injection (Scaffidi et al., Cochrane Database of Systematic Reviews, 2025).

‍

The operation is performed under general anesthesia, laparoscopically or robotically (Midya et al., Cochrane Database of Systematic Reviews, 2022). Typically five small upper-abdominal ports are placed for the camera, a liver retractor, and working instruments. The surgeon divides the anterior phrenoesophageal ligament at the hiatus to expose the front of the lower esophagus, using a limited hiatal dissection that preserves the posterior esophageal attachments to minimize postoperative reflux (Midya et al., Cochrane Database of Systematic Reviews, 2022).

The myotomy is then carried across the esophagogastric junction, dividing the circular and longitudinal muscle fibers to expose the underlying mucosa — extended at least 4–6 cm (often 5–7 cm) up the esophagus and 2–3 cm onto the gastric cardia to eliminate the gastric sling fibers (Blonski et al., Dysphagia, 2023; Savarino et al., Nature Reviews Disease Primers, 2022). Many surgeons perform intraoperative endoscopy to confirm the myotomy is complete and to rule out a mucosal perforation (Midya et al., Cochrane Database of Systematic Reviews, 2022). A partial fundoplication — an anterior Dor or posterior Toupet wrap — is then constructed to restore an antireflux barrier and, in the case of the Dor, to buttress the exposed mucosa (Blonski et al., Dysphagia, 2023). Robotic assistance follows identical principles and has been associated with a lower rate of intraoperative mucosal perforation, though without a clear advantage in symptom relief or long-term outcomes over laparoscopy (Savarino et al., Nature Reviews Disease Primers, 2022).

‍

Heller myotomy is a very safe operation in experienced hands, but patients are counseled candidly about potential complications (Savarino et al., Nature Reviews Disease Primers, 2022):

• Esophageal or gastric mucosal perforation — the most common intraoperative complication (<5% of cases); when recognized during surgery it is repaired primarily and buttressed with the Dor fundoplication, usually without long-term consequence (Blonski et al., Dysphagia, 2023; Fisichella, JOMI, 2024).

• Leak — an unrecognized perforation can lead to a postoperative leak, sometimes requiring endoscopic stenting or washout/drainage; prior botulinum toxin injection or reoperation raises this risk (Mustian & Wong, Abdominal Radiology, 2025; Fisichella, JOMI, 2024).

• Postoperative gastroesophageal reflux — reported by ~17.5% after laparoscopic Heller myotomy (and in ~20–30% without fundoplication), markedly reduced by the partial wrap; it can lead to erosive esophagitis over time (Khashab et al., ASGE Guideline, 2020; Mustian & Wong, Abdominal Radiology, 2025).

• Persistent or recurrent dysphagia — in about 5–15% of patients, from an incomplete myotomy, an overly tight wrap, or progression of the disease (Khashab et al., ASGE Guideline, 2020).

• Pneumothorax, hemothorax, bleeding, and splenic injury (Aaron et al., ACS Gastrointestinal Surgical Emergencies, 2021; Savarino et al., Nature Reviews Disease Primers, 2022).

• General surgical/anesthetic risks, including those related to pneumoperitoneum.

‍

Recovery after laparoscopic Heller myotomy is generally quick, with an average hospital stay of roughly 1–3 days (Aaron et al., ACS Gastrointestinal Surgical Emergencies, 2021). Many programs obtain a water-soluble contrast swallow before starting oral intake to confirm there is no leak, then advance the diet in stages — clear liquids, to full liquids, to soft foods, to a regular diet — over the following weeks as swallowing normalizes (Fisichella, JOMI, 2024). Because the esophagus has been chronically obstructed, patients are coached to eat slowly, chew thoroughly, and sit upright during and after meals. Most return to light activity within one to two weeks, with heavy lifting restricted while the port sites and any hiatal repair heal. Early, dramatic improvement in the ability to swallow is typical (Blonski et al., Dysphagia, 2023).

‍

Most patients enjoy durable relief of dysphagia, but achalasia is a chronic, progressive disorder, and lifelong follow-up is important (Savarino et al., Nature Reviews Disease Primers, 2022). Long-term data show excellent control of vomiting (~97.5% free at 10 years) and chest pain (~96.3% free at 10 years), while dysphagia recurs in roughly 20% of patients by 10 years and overall clinical success (Eckardt ≤3) is maintained in about three-quarters (Fukushima et al., Surgical Endoscopy, 2021). Satisfaction can decline over very long follow-up (to ~75% at 15 years) owing to both recurrent dysphagia and reflux, which is why structured endoscopic surveillance matters — both to manage reflux/esophagitis and, over decades, to monitor for the small increased risk of esophageal cancer associated with long-standing achalasia (Savarino et al., Nature Reviews Disease Primers, 2022). Recurrent symptoms are managed in a stepwise fashion with pneumatic dilation, POEM, or redo myotomy, reserving esophagectomy for end-stage disease (Saleh et al., Gastroenterology, 2023; Fisichella, JOMI, 2024).

‍

Outcomes in esophageal surgery are strongly tied to surgeon and center experience — in experienced hands, laparoscopic Heller myotomy produces symptomatic improvement in well over 90% of patients with a short hospital stay and a low complication rate, while an inadequate myotomy or an incorrectly constructed wrap is a leading cause of failure (Aaron et al., ACS Gastrointestinal Surgical Emergencies, 2021; Fisichella, JOMI, 2024). As a board-certified surgeon with advanced expertise in minimally invasive and robotic foregut surgery, Dr. Nestor de la Cruz-Muñoz, MD, FACS, DABOM emphasizes the rigorous, guideline-concordant workup that defines modern achalasia care — upper endoscopy to exclude pseudoachalasia and malignancy, high-resolution manometry to confirm the diagnosis and subtype, and timed barium esophagram to assess emptying — before recommending surgery (Savarino et al., Nature Reviews Disease Primers, 2022; Khashab et al., ASGE Guideline, 2020). He performs a complete, appropriately extended myotomy paired with a tailored partial fundoplication (Dor or Toupet) to balance durable dysphagia relief against reflux, uses intraoperative endoscopy to confirm adequacy and integrity of the repair, and individualizes the choice among Heller myotomy, POEM, and pneumatic dilation to the patient's achalasia subtype and anatomy (Blonski et al., Dysphagia, 2023; Scaffidi et al., Cochrane Database of Systematic Reviews, 2025).

‍

Expected Swallowing & Symptom Improvement

Unlike a weight-loss operation, Heller myotomy is intended to restore swallowing, and symptom relief is the primary measure of success (Khashab et al., ASGE Guideline, 2020). Expected outcomes include dysphagia improvement in roughly 87–90% of patients, with high rates of freedom from regurgitation, vomiting, and chest pain sustained over 10 years, and an Eckardt score (the validated achalasia symptom score) falling to ≤3 in the large majority (Fukushima et al., Surgical Endoscopy, 2021; Blonski et al., Dysphagia, 2023). Objectively, the operation lowers LES pressure and improves esophageal emptying; type I and II patients do particularly well (Werner et al., New England Journal of Medicine, 2019). Patients are counseled that some dysphagia can recur over years and is typically treatable with dilation or revision (Khashab et al., ASGE Guideline, 2020).

‍

Expected Nutritional Recovery

Many achalasia patients arrive malnourished and underweight from months or years of impaired swallowing and weight loss, so the nutritional goal after Heller myotomy is recovery and stabilization of weight, not weight loss (Werner et al., New England Journal of Medicine, 2019; Savarino et al., Nature Reviews Disease Primers, 2022). As swallowing is restored, most patients regain the ability to eat a normal, balanced diet and recover lost weight, supported by staged diet advancement and dietitian guidance during the early postoperative weeks (Fisichella, JOMI, 2024). Ongoing or worsening dysphagia with failure to regain weight should prompt evaluation for an incomplete myotomy, an overly tight wrap, or recurrent disease (Khashab et al., ASGE Guideline, 2020).

‍

Reflux Prevention Strategy

Because dividing the LES removes the natural antireflux barrier, reflux prevention is engineered into the operation and reinforced afterward (Savarino et al., Nature Reviews Disease Primers, 2022). The cornerstone is the routine partial fundoplication performed at the time of myotomy, which cuts objective reflux from ~48% (myotomy alone) to ~9% without compromising dysphagia relief, provided the wrap is partial rather than complete (Savarino et al., Nature Reviews Disease Primers, 2022). Additional measures include a limited hiatal dissection that preserves posterior esophageal attachments, postoperative acid suppression when indicated, and long-term endoscopic surveillance to detect and treat reflux esophagitis early (Midya et al., Cochrane Database of Systematic Reviews, 2022; Mustian & Wong, Abdominal Radiology, 2025).

‍

Recurrent or persistent symptoms after Heller myotomy are managed in a stepwise, individualized fashion (Saleh et al., Gastroenterology, 2023). Because esophageal cancer can mimic recurrent achalasia, upper endoscopy to exclude malignancy is an essential first step when dysphagia recurs after a symptom-free interval (Fisichella, JOMI, 2024). Options include:

• Pneumatic dilation — effective for recurrent dysphagia, with reported success rates of 57–96% (Saleh et al., Gastroenterology, 2023).

• POEM as rescue therapy — increasingly used and often preferred for recurrent disease, allowing a fresh myotomy without reoperating through scarred tissue (Mustian & Wong, Abdominal Radiology, 2025; Saleh et al., Gastroenterology, 2023).

• Revisional (redo) Heller myotomy — efficacy of ~71–90%, but technically demanding owing to adhesions, fibrosis, and loss of tissue planes (Saleh et al., Gastroenterology, 2023).

• Esophagectomy — reserved as a last resort for end-stage, dilated/sigmoid esophagus after other therapies fail (Fisichella, JOMI, 2024).

‍

Rather than reducing body mass, the priority after Heller myotomy is rebuilding the lean mass and nutritional reserves eroded by achalasia (Werner et al., New England Journal of Medicine, 2019). Chronic dysphagia commonly produces weight loss and muscle depletion before surgery, so postoperative care centers on restoring adequate protein and caloric intake as swallowing normalizes, with dietitian support and a graded return to normal eating (Fisichella, JOMI, 2024). A progressive resumption of physical activity complements improved nutrition to rebuild strength and functional capacity.

‍

Heller myotomy for achalasia is covered as a medically necessary treatment for a documented motility disorder, in contrast to elective weight-loss surgery. Payers expect documentation establishing the diagnosis — upper endoscopy excluding malignancy/pseudoachalasia, high-resolution manometry confirming achalasia (and its Chicago Classification subtype), and often a timed barium esophagram — together with the symptomatic indication (Savarino et al., Nature Reviews Disease Primers, 2022; Khashab et al., ASGE Guideline, 2020). Specific coverage, documentation, coding, and any pre-authorization requirements should be confirmed with each individual plan.

‍

• Confirm the diagnosis — upper endoscopy to exclude pseudoachalasia/malignancy and high-resolution manometry to confirm achalasia and subtype (type I/II vs. III, which influences whether Heller myotomy or POEM is preferred) (Savarino et al., Nature Reviews Disease Primers, 2022; Blonski et al., Dysphagia, 2023).

• Assess esophageal emptying and anatomy — timed barium esophagram; evaluate for a dilated/sigmoid (megaesophagus) configuration (Fisichella, JOMI, 2024).

• Nutritional assessment and optimization in patients who have lost significant weight (Werner et al., New England Journal of Medicine, 2019).

• A pre-operative clear-liquid diet for a period before surgery to clear the obstructed esophagus and reduce aspiration risk at induction.

• Standard pre-anesthesia evaluation and confirmation of fitness for laparoscopy/pneumoperitoneum (Mustian & Wong, Abdominal Radiology, 2025).

‍

Oral intake is typically resumed after a contrast swallow confirms no leak, then advanced in stages — clear liquids, full liquids, soft foods, and finally a regular diet — over the following weeks (Fisichella, JOMI, 2024). Patients are coached to eat small, measured amounts, chew thoroughly, stay upright during and after meals, and avoid eating late at night. Because many patients were malnourished beforehand, the emphasis is on restoring adequate protein and calories to regain lost weight, with dietitian support. Acid-suppressing medication is used as indicated given the post-myotomy reflux risk (Mustian & Wong, Abdominal Radiology, 2025).

‍

Early walking is encouraged to reduce pulmonary and clot-related complications, and with the minimally invasive approach there are no large incisions, allowing a return to light activity within one to two weeks (Aaron et al., ACS Gastrointestinal Surgical Emergencies, 2021). Heavy lifting and strenuous core exertion are restricted for several weeks to protect the port sites and any hiatal repair. Patients then progressively resume aerobic activity and, later, resistance training, with the goal of rebuilding the conditioning and muscle mass lost during the period of impaired nutrition.
