Several multi-institutional prospective randomized trials have demonstrated short-term benefits using laparoscopy.
Now the laparoscopic approach is accepted as an alternative to open surgery for colon cancer.
However, in prior trials, the transverse colon was excluded.
It has not been determined whether laparoscopy can be used in the setting of transverse colon cancer.
|Distal resection margins were similar between groups|
Dr Lee and colleagues from South Korea evaluated the peri-operative clinical outcomes and oncological quality by pathologic outcomes of laparoscopic surgery for transverse colon cancer.
The team analyzed the medical records of patients who underwent laparoscopic colorectal resection from 2004 to 2007.
Computed tomography, barium enema, and colonoscopy were performed to localize the tumor preoperatively.
Extended right hemicolectomy, transverse colectomy, and extended left hemicolectomy were performed for transverse colon cancer.
Surgical outcomes and pathologic outcomes were compared between transverse colon cancer and other site colon cancer.
The researchers reported that of the 312 colorectal cancer patients, 94 patients underwent laparoscopic surgery for other site colon cancer.
The remaining 34 patients underwent laparoscopic surgery for transverse colon cancer.
Patients with transverse colon cancer were similar to patients with other site colon cancer in age, gender, body mass index, operating time, blood loss, time to pass flatus, start of diet, hospital stay, tumor size.
Distal resection margin, proximal resection margin, number of lymph nodes, and radial margin were also similar between groups.
The team noted that 1 case with transverse colon cancer, and 3 cases with other colon cancer sites were converted to open surgery.
Dr Lee's team concluded, "Laparoscopic surgery for transverse colon cancer and other site colon cancer had similar peri-operative clinical and acceptable pathological outcomes.
