All tumors <30 mm achieved complete resection, while piecemeal retrieval was required in 9.6% of 30–50 mm tumors and 89.5% of ≥50 mm tumors. Univariable Analysis In univariable analysis for piecemeal retrieval, both tumor dimensions were highly significant: longitudinal length (OR = 1.35 per 10 mm, 95% CI: 1.16–1.57, p < 0.001) and transverse length (OR = 1.53 per 10 mm, 95% CI: 1.29–1.81, p < 0.001).
