Insights
Laparoscopic Heller cardiomyotomy (LHM) without an antireflux procedure effectively treats achalasia. Previous treatments like Botox may increase surgical complexity and complication risks during LHM.
Area of Science:
- Gastroenterology
- Minimally Invasive Surgery
Background:
- Laparoscopic Heller cardiomyotomy (LHM) is a standard treatment for achalasia.
- Controversies exist regarding the optimal extent of myotomy and the necessity of an antireflux procedure during LHM.
Observation:
- A retrospective review analyzed 40 patients undergoing LHM for achalasia at a single institution.
- The study focused on LHM performed without an antireflux procedure.
- Sixty-five percent of patients had prior medical management (Botox or LES dilatation).
Findings:
- LHM without an antireflux procedure yielded excellent clinical outcomes, with low dysphagia scores and controlled reflux symptoms in most patients.
- Patients with prior Botox injections experienced longer operating times and a higher incidence of intraoperative mucosal injury.
- Postoperative evaluation showed a mean dysphagia score of 0.2 and a mean heartburn score of 3.2.
Implications:
- LHM without an antireflux procedure is a safe and effective treatment for achalasia.
- Previous medical interventions for achalasia may complicate LHM and increase the risk of intraoperative injury.
- Further research may refine surgical techniques for patients with prior treatments.
Abstract:
Certain technical features of laparoscopic Heller cardiomyotomy (LHM) remain controversial, including the extent of the myotomy and the indication for an antireflux procedure. We completed a retrospective chart review of all patients who underwent LHM for achalasia at 1 tertiary care institution to review our institutional experience with LHM without an antireflux procedure. Forty patients underwent a LHM performed by 2 surgeons, 65% of whom had previous medical management (Botox: 12 patients, LES dilatation: 14). The operating time was significantly increased in patients with Botox injections (98.3 vs. 71.1 minutes, P = 0.005). There were 3 intraoperative complications (mucosal injury in 3 patients, 2 had Botox injections). Postoperative evaluation demonstrated a mean dysphagia score of 0.2, a mean heartburn score of 3.2, and a mean LES pressure of 6.32 mm Hg. Thirty-two patients are maintained on acid-suppressing medications with good control of reflux symptoms. LHM without an antireflux procedure achieves excellent clinical outcomes in most patients with achalasia regardless of previous medical management. Previous medical management may present a greater technical challenge and may place patients at increased risk of mucosal injury.
