Letter to the editor regarding “Hepatectomy strategy for T2 gallbladder cancer between segment IVb and V resection and wedge resection: A propensity score-matched study”

We read with great interest the article by Chen et  al showing that segment IVb/V resection (S4b5R) had a lower recurrence rate than wedge resection (WR) in gallbladder cancer.1 I would like to congratulate the authors for their well-designed research on a topic that has long been debated; however, I would also like to raise a concern regarding the definition of S4b5R, which was not clearly described in their study.
