Purpose: The COST study trial has demonstrated oncological safety by using laparoscopy for colon cancer. However, in a prior trial, the transverse colon was excluded. Therefore, it has not been determined whether laparoscopy can be used in the setting of transverse colon cancer. Moreover, a transverse colectomy for transverse colon cancer is controversial. This study evaluated the peri-operative and short-term oncological outcomes of a laparoscopic transverse colectomy. Methods: A retrospective review of patients with colorectal cancer treated using laparoscopy from August 2004 to August 2007 was conducted. Peri-operative and short-term oncological outcomes were compared between an extended right or left colectomy and a transverse colectomy. Results: Of 234 patients, 26 patients underwent laparoscopic surgery for transverse colon cancer. Extended right & left colectom were performed in 20 cases, and a transverse colectomy was performed in 6 cases. There were no significant differences between the two groups in terms of age, gender, BMI, blood loss, time to pass flatus, start of diet, hospital stay, tumor size, number of lymph nodes, and radial margin. The distal and the proximal resection margins of an extended Rt. or Lt. colectomy were longer than those of a transverse colectomy. One transverse colectomy was converted to open surgery because of a T4 lesion of transverse colon cancer. There were no differences between the two groups in terms of morbidity and mortality. Conclusions: The results of this study show that a laparoscopic transverse colectomy has acceptable peri-operative and short-term oncological outcomes compared to an extended right and left colectomy. However, further investigations are needed to establish the long-term oncological safety of laparoscopic surgery, including transverse colectomy, for transverse colon cancer.
