Endoscopic Submucosal Dissection: A Safe and Effective Alternative to Surgical Intervention for Esophageal Hemangioma

BACKGROUND

Hemangiomas represent 3% of all benign esophageal tumors. Conventional esophagectomy is the standard treatment with its invasive nature and possible surgical complications. Now, less invasive techniques are used with better results. Endoscopic submucosal dissection (ESD) is one of the novel noninvasive methods used for en bloc removal of tumors. No available data about the use of ESD in removing esophageal hemangioma. Here, we studied the validity and safety of ESD as a minimally invasive procedure to remove esophageal hemangioma.

METHODS

Three patients were diagnosed with esophageal hemangioma and underwent ESD with en bloc resection. Endoscopic ultrasound (EUS) was performed before ESD to better evaluate the layer of origin and vascularity and guard against perforation. Patients were followed up postintervention to document possible complications.

RESULTS

Among the 3 studied patients, one presented with chronic abdominal pain, the second was complaining of dysphagia, and the third patient was diagnosed accidentally. Pathology reports confirmed the diagnosis of hemangiomas in all cases with no atypia and complete removal of the lesions. No complications were reported during the procedure or over the follow-up period.

CONCLUSIONS

ESD is a proper, minimally invasive method with good en bloc resection that can be used in cases of esophageal hemangiomas.

Successful en bloc resection of an esophageal hemangioma by combined EBL & EMR: a case report and technical review

A 58-year-old male was diagnosed esophageal hemangioma during a endoscopy in regular examination. The patient was referred to the department of gastroenterology in our hospital to treatment. Combined endoscopic band ligation (EBL) and endoscopic mucosal resection (EMR) was performed for diagnostic treatment. Histopathological results revealed hemangioma. Even though several approaches such as esophagectomy, endoscopic removal, sclerotherapy, and laser therapy have been used to remove the esophageal hemangiomas, recently less invasive methods were preferred. Here we describe a case of esophageal hemangioma removed by EBL & EMR.

Indications of endoscopic submucosal dissection for symptomatic benign gastrointestinal subepithelial or carcinoid tumors originating in the submucosa

Endoscopic submucosal dissection (ESD) for upper gastrointestinal (GI) subepithelial tumors (SETs) originating in the muscularis propria (MP) layer is associated with numerous issues regarding secure closure and measures against accidental perforation. However, symptomatic benign GI SETs or carcinoid tumors originating in the submucosa (SM) may be safely resected en-bloc using ESD. In this study, the feasibility and safety of ESD as a novel method for endoscopic resection for such GI SETs revealed on endoscopic ultrasonography (EUS) was investigated. A total of 12 consecutive cases of patients with symptomatic benign SETs (n=3; 1 esophageal hemangioma and 2 gastric lipomas) or small carcinoid tumors (n=9; <10 mm, with an extremely low risk of metastasis) originating in the SM as determined on EUS, between March, 2009 and April, 2013, were retrospectively reviewed. The lesions were resected by ESD after confirming that the tumors originated from the SM. The complication rate following en-bloc resection was also determined. En-bloc resection was achieved in all 12 cases, the mean procedure time was 45 min (range, 20-120 min) and no complications occurred intra- or postoperatively. There was no tumor recurrence or disease-related mortality reported during the follow-up period (median follow-up time, 13.4 months). Histopathological curative resection was achieved with ESD without complications in all 9 cases with carcinoid tumors. Therefore, if EUS reveals a SET originating in the SM without infiltration of the MP and resection is indicated due to the presence of abdominal symptoms, ESD may be a feasible option for diagnostic treatment with minimal invasiveness. However, larger-scale prospective studies are required to establish the feasibility and safety of this procedure.
