Abstract

Background

Epiphrenic diverticula are rare esophageal diseases often associated with motility disorders such as achalasia. We present a case of bilateral epiphrenic diverticula in a patient with achalasia type III who presented with dysphagia. This video demonstrates the surgical technique of robotic-assisted bilateral epiphrenic diverticulectomy with Heller myotomy and Dor fundoplication, highlighting the six essential surgical steps.

Methods

A 72-year-old female presented with dysphagia for 3 years. An esophagogastroduodenoscopy revealed two epiphrenic diverticula without food content retention. A barium swallow revealed two epiphrenic diverticula, measuring 3.3 cm and 1.2 cm in diameter, on right and left side walls of distal esophagus, respectively. Esophageal manometry showed the lower esophageal sphincter (LES) pressure was 25.6 mmHg (normal <15 mmHg). Subsequently, both the acid exposure time and the DeMeester score indicated normal levels of acid exposure. The patient underwent robotic-assisted surgery. The diverticulectomy was performed using stapling device under endoscopic guidance, followed by standard myotomy. Additionally, Dor fundoplication was performed to complete procedure.

Results

Postoperatively, the patient recovered well. An upper gastrointestinal study demonstrated an adequate myotomy without evidence of leak or residual epiphrenic diverticula. Further postoperative evaluation, including esophageal manometry, showed normal LES pressure of 12.8 mmHg, the postoperative acid exposure time of 0.0%, and the DeMeester score of 0.20, that indicating normal levels of acid exposure. The patient resumed a liquid diet on postoperative day 4 and a soft diet on postoperative day 7. Based on these results, the patient’s dysphagia was resolved, and there was an absence of gastroesophageal reflux symptoms.

Conclusion

Bilateral epiphrenic diverticula are extremely rare, and require complex procedure. Robotic-assisted surgery has the potential to enhance the facilitation of surgical treatment for this condition. The robotic tools are precise and maneuverable, making it possible to perform intricate surgical procedures in tight angles and confined spaces, such as the hiatal area. This technique offers several advantages over conventional laparoscopic surgery, and should therefore be considered for the treatment of bilateral epiphrenic diverticula.
