The treatment for cancer of rectum (back passage) has been performed by conventional open surgery for years. This has been so essentially for two reasons. Firstly, the lack of irrefutable evidence (though sufficient evidence has been present for years) and secondly for the want of skilled surgeons. The first deficit has now been fulfilled by a large research study.
Incidentally, the recent findings of the long-term oncologic outcomes of the landmark “Colorectal Cancer Laparoscopic or Open Resection (COLOR) II trial” are indeed heartening.
