Aim The optimal surgical method for cancer of the mid‐transverse colon has not been well established. The present study aimed to explore the distribution of lymph node metastasis and compare the outcomes of extended and transverse colectomies for cancer of the mid‐transverse colon. Methods We retrospectively analysed the data of patients with cancer of the mid‐transverse colon treated with either an extended hemicolectomy (right or left) or a transverse colectomy. A propensity score matching analysis was performed to rule out selection bias, and short‐term and survival outcomes were compared. The distribution of lymph node metastasis was also investigated. Results A total of 107 patients were included, 70 of whom underwent an extended colectomy while 37 underwent a transverse colectomy. There were no significant differences in the operation time, postoperative complications, hospital stay, 3‐year disease‐free survival (86.5% vs. 90.9%, P = 0.675) and 5‐year overall survival (87.4% vs. 93.0%, P = 0.349) between the two groups after propensity score matching. However, metastases were observed in the lymph nodes along the right colic artery (pericolic [#211], 14.0%; intermediate [#212], 8.2%; apical [#213], 9.8%) in the extended colectomy group. Conclusion Extended and transverse colectomies showed similar short‐term and long‐term outcomes for mid‐transverse colon cancer. However, care should be taken to determine the extent of resection considering the possibility of metastatic lymph nodes along the right colic artery.
