Background/Aims

To investigate whether the EndoLifter (Olympus), a counter-traction device facilitating submucosal dissection, can accelerate endoscopic submucosal dissection (ESD).

Methods

Two endoscopists (novice/expert in ESD) performed 64 ESDs (artificial 3-cm lesions) in 16 ex vivo pig stomachs: per stomach, two at the posterior wall (forward approach) and two at the lesser curvature (retroflex approach). Per approach, one lesion was dissected with (EL+) and one without (EL-) the EndoLifter. The submucosal dissection time (SDT), corrected for specimen size, and the influence of ESD experience on EndoLifter usefulness were assessed.

Results

En bloc resection rate was 98.4%. In the forward approach, the median SDT was shorter with the EndoLifter (0.56 min/cm² vs. 0.91 min/cm²), although not significantly (p=0.09). The ESD-experienced endoscopist benefitted more from the EndoLifter (0.45 [EL+] min/cm² vs. 0.68 [EL-] min/cm², p=0.07) than the ESD-inexperienced endoscopist (0.77 [EL+] min/cm² vs. 1.01 [EL-] min/cm², p=0.48). In the retroflex approach, the median SDTs were 1.06 (EL+) and 0.48 (EL-) min/cm² (p=0.16). The EndoLifter did not shorten the SDT for the ESD-experienced endoscopist (0.68 [EL+] min/cm² vs. 0.68 [EL-] min/cm², p=0.78), whereas the ESD-inexperienced endoscopist seemed hindered (1.65 [EL+] min/cm² vs. 0.38 [EL-] min/cm², p=0.03).

Conclusions

In gastric ESD, the EndoLifter, in trend, shortens SDTs in the forward, but not in the retroflex approach. Given the low numbers in this study, a type II error cannot be excluded.
