The role of Ivor Lewis esophagectomy in the treatment of achalasia with megaesophagus: A case report.

ABSTRACT

Introduction: Achalasia with megaesophagus is a pathology characterized by widespread and irregular dilation of the esophageal lumen. In most cases, this dilation is caused by contraction and subsequent failed relaxation of the lower esophageal sphincter (LES). It may be associated with a partial or complete slowing of the esophageal peristalsis. Case overview We present the case of a 58-year-old woman who developed dysphagia, regurgitation, and substantial weight loss (11 kg) over a span of 1 year. Symptomatic achalasia with megaesophagus was diagnosed following chest and abdominal computed tomography (CT) with contrast and transit RX with gastrografin and esophageal manometry. The patient refuse all minimally endoscopic treatments and opted straightly for the treatment with esophagectomy sec. Ivor-Lewis. At the 6-month follow-up, the patient appeared in excellent general clinical condition and oral gastrografin radiography (OGR) showed good channeling. Discussion: Patients require medical attention when presenting with achalasia that has eroded the esophageal wall enough to form a megaesophagus. Early and minimally invasive treatments (i.e., medical therapy, endoscopic dilation, and myotomy) are insufficient at this stage, and thus esophageal surgery is required. Among the most common surgical approaches, we must mention esophagectomy sec. McKeown and esophagectomy with interposition of a colic loop sec. Wilkins; however, based on our experience, esophagectomy sec. Ivor-Lewis with intrathoracic anastomosis leads to excellent results and can therefore be considered a valid alternative for treating complex cases. Conclusions: Subtotal esophagectomy sec. Ivor-Lewis with intrathoracic anastomosis is effective in treating achalasia with megaesophagus.
