Pure transanal endoscopic colectomy for ascending colon cancer.

BACKGROUND

Previous studies have demonstrated that pure transanal endoscopic surgery is safe and feasible in the treatment of rectal cancer. However, the role of pure transanal endoscopic colectomy in ascending colon cancer (ACC) treatment has not been evaluated. We report a case of transanal endoscopic surgery for ACC.

METHODS

A 35-year-old woman was treated for ACC, using a transanal endoscopic surgery device as the operation platform, and pure transanal endoscopic right hemicolectomy without transabdominal assistance was safely performed. An instrument suture, side-to-side, ileocolic anastomosis was performed. Operative time was 245 min and intraoperative blood loss was 60 ml.

RESULTS

The patient recovered well from the surgery. Compared with the traditional approach, this approach was less invasive and resulted in satisfactory outcomes and cosmesis (no scar).

CONCLUSIONS

Application of pure transanal endoscopic colectomy without abdominal assistance to ACC appears to be feasible and safe.
