Esophageal epiphrenic diverticulum treated with laparoscopic surgery in a patient with systemic sclerosis: A rare case report.

INTRODUCTION AND IMPORTANCE

Systemic sclerosis is a disease characterized by autoimmune inflammation, fibrosis of the skin and internal organs, and vasculopathy. Diverticula found in the intestines are a common feature in patients with systemic sclerosis, but esophageal epiphrenic diverticulum is extremely rare. We present a rare case of esophageal epiphrenic diverticulum treated with laparoscopic diverticulectomy and Heller myotomy in a patient with systemic sclerosis.

CASE PRESENTATION

A 73-year-old woman had been treated with prednisolone for diffuse systemic sclerosis with interstitial pneumonia. The patient had complained of chronic dysphagia and reflux symptoms. A small and asymptomatic diverticulum was first detected four years ago. Endoscopy repeated because of exacerbation of symptoms revealed an enlarged diverticulum. Therefore, the patient underwent laparoscopic diverticulectomy and Heller myotomy with partial fundoplication. Her postoperative course was uneventful, and her symptoms were relieved.

CLINICAL DISCUSSION

Although patients with systemic sclerosis commonly present with reflux esophagitis, they rarely develop achalasia-like change that leads to an esophageal diverticulum. There are several treatment options for esophageal diverticulum, including transhiatal surgery, thoracic surgery, or endoscopic treatment.

CONCLUSION

Clinicians must pay attention to patient symptoms because the worsening of dysphagia might suggest an underlying achalasia-like change or epiphrenic diverticulum in the esophagus. Surgeons should determine the treatment approach with considerations of the patient's background, the location and size of the diverticulum, and other factors.
