Endoscopic resection of giant fibrovascular esophageal polyps
- 115 Downloads
Giant fibrovascular esophageal polyps are rare benign intraluminal tumors that originate from the submucosa of the cervical esophagus [Owens et al. (JAMA 103: 838-842, 1994), Totten et al. (JAMA 25:606–622, 1953)]. Due to their indolent course, these tumors tend to reach enormous proportions before patients develop symptoms. Accurately diagnosing these tumors is difficult, as endoscopy may miss 25% of these lesions because these polyps exhibit normal intact esophageal mucosa [Levine et al. (JAMA 166: 781–787, 1996)].
Surgical resection has been the treatment of choice. We present a video that illustrates the feasibility of an endoscopic approach.
A 62-year-old man presented to our clinic with a pedunculated esophageal mass. During this time, he developed progressive dysphagia to solid foods. A complete workup confirmed the presence of a giant polyp and endoscopic resection under general anesthesia was planned. Using an endoscopic snare-technique, a 16 cm × 3 cm polyp was amputated and retracted out of the oropharynx. Upon repeat endoscopy a second 7 cm × 3 cm polyp was discovered originating proximal to the larger polyp. Again, removal of this polyp was attempted using a snare-technique. Following amputation of the polyp, a broad-based component of the polyp remained. Given its proximal location in the esophagus, we were able to use a snare to pull the broad base of the remaining polyp into the oropharynx and remove it at its origin. Postoperative endoscopy and endoscopic ultrasound confirmed that the polyps were completely removed and the muscular resection bed was hemostatic. Clinically, the patient’s symptoms resolved and he encountered no adverse sequela as a result of the operation.
Giant fibrovascular esophageal polyps are rare benign intraluminal tumors that can lead to obstructive symptoms. Surgical resection is the treatment of choice, and may be possible with an endoscopic approach. An endoscopic snare technique can be used to resect these lesions while minimizing patient morbidity.
