Abstract
BACKGROUND AND AIM
Gastric inflammatory fibroid polyps constitute only 0.1% of all gastric polyps. They are usually asymptomatic and are most often found in the antrum. These lesions are in the majority of cases amenable to resection by snare polypectomy. However, there are rare case reports of gastric IFP requiring resection by endoscopic submucosal dissection. This study aimed to evaluate the effectiveness and safety of endoscopic submucosal dissection in the management of gastric inflammatory fibroid polyps not amenable to resection with snare polypectomy because of large size and/or deep subepithelial engagement.
METHODS
A retrospective study of all consecutive patients who undergone endoscopic submucosal dissection for gastric inflammatory fibroid polyps between January 2011 and December 2020 was performed.
MAJOR RESULTS
There were 9 cases of gastric inflammatory fibroid polyps resected by endoscopic submucosal dissection. Most patients were female (7/9) with a mean age of 62.2 years. All gastric inflammatory polyps were described as solitary antral subepithelial lesions with mean diameter of 16.7 mm. Helicobacter pylori was detected in only one patient. At endoscopic ultrasound, these lesions were uniformly described as well-circumscribed, homogeneous lesions located at muscularis mucosa and submucosa without invasion of muscularis propria. All lesions were successfully resected en-bloc by endoscopic submucosal dissection and complete resection with free margins was obtained in 8/9 specimens. Adverse events were reported in 2/9 cases including one case of intra-procedural bleeding successfully controlled with hemostatic clips and one case of aspiration pneumonia that evolved favorably. Mean follow-up duration was 33.7 months (range 0-120) and no delayed complications or cases of recurrence were detected during follow-up.
CONCLUSIONS
Endoscopic submucosal dissection appears to be a safe and effective approach for resection of gastric inflammatory fibroid polyps that present as large subepithelial lesions if performed by experienced endoscopists after adequate characterization by endoscopic ultrasound with high rates of technical success and low recurrence rates. .
