Transcecal endoscopic appendectomy for management of complex appendiceal polyps extending into the appendiceal orifice.

Endoscopic resection of appendiceal orifice (AO) polyps extending inside the appendiceal lumen is challenging given the inability to determine polyp lateral margins and risk of appendicitis. Transcecal endoscopic appendectomy (TEA) ensures en bloc resection of these complex polyps. This case series includes patients who underwent TEA by a single endoscopist in the United States.
