Gastrocolic ligament (GCL) is a portion of the greater omentum. It attaches the greater curvature of the stomach and the first part of the duodenum to the transverse colon, and it is fused with the mesocolon. The GCL lymph nodes (GCLNs) were grouped as gastroepiploic (No. 204), infrapyloric (No. 206), and superficial pancreatic (No. 214v), as described previously.1,2 In 3.8–9% of hepatic flexural colon cancer (HFC) and transverse colon cancer (TCC), lymph node metastases occurred in the GCL.2–5 However, most previous reports have been limited case series with GCLN dissection for colon cancer, and few data were provided regarding complications and the long-term survival after GCLN dissection. This study aimed to investigate the incidence of and risk factors for GCLN metastases, the morbidity, and prognosis after GCLN dissection for HFC and TCC. From 2008 to 2018, the data of patients treated by D3 lymph node dissection for right-sided colon cancer and TCC were retrieved (Supplementary material S1). Patients with HFC or advanced Shenghui Huang, Xiaojie Wang and Yu Deng contributed equally to this work.

TCC received GCLN dissection in this study. Patients with ascending colon cancer or ileocecal cancer did not receive GCLN dissection but a standard right hemicolectomy in our center6 (Fig. 1a–f). The incidence and predictors of lymph node metastases in the GCL were analyzed for patients with HFC and TCC who underwent GCLN dissection. The disease-free survival rates (DFS) were compared between GCLN-positive patients and stage-III patients after GCLN dissection for HFC and TCC. The complications of patients who did and did not undergo GCLN dissection were compared. A total of 998 patients with right-sided colon cancer were included, and 432 underwent GCLN dissection for TCC and HFC. The incidences of GCLN metastases were 5.8% among all 432 patients (Fig. 1g) and 11.8% in the 207 patients with pN + status. The incidences of GCLN metastases in patients with pT1–2, pT3, and pT4 disease were 0,
