Abstract
Background and study aims 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.
Patients and methods This case series includes patients who underwent TEA by a single endoscopist in the United States. Technical success was defined as achieving complete removal of the appendix along with AO polyp in an en bloc fashion.
Results In total, nine patients were included (mean age 69.7 ± 9.6 years). The average appendix size was 4.07 ± 2.02 cm. Technical success was achieved in 100% of the patients. The average procedure length was 118.1 ± 44.21 minutes. The en bloc resection rate, R0 resection rate, and curative resection rates were 100%. Patients were observed for an average of 3.1 ± 1.6 days. One patient developed loculated fluid collection 9 days post procedure, which resolved on its own with oral antibiotic therapy. No other adverse events were recorded
Conclusions This was an early study of the feasibility of TEA in the United States. This novel technique, in early-stage development, is potentially safe and associated with a minimal risk profile in expert hands. Further prospective studies are needed to standardize the technique.
