The emergence of minimally invasive colorectal surgery (laparoscopy and surgery through single port) has made a breakthrough in surgery of rectal lesions. This new technique allows the removal of the tumor, providing the benefits of minimally invasive surgery, such as early recovery, less postoperative pain and reduced postoperative stay.
Despite these advantages, performing surgery rectal resection may lead to the appearance of complications both abdominal level as those derived from the performance of an anastomosis (joining the ends), such as the suture dehiscence, appearance continence problems, among others.
Transanal minimally invasive surgery
Among the latest advances in addressing the rectal pathology included the transanal minimally invasive surgery (TAMIS, its acronym in English).
This technique, initially described by the group of Colorectal Surgery in Orlando in 2010, enables extirpation of benign rectal lesions, unresectable polyps endoscopically, and some malignant lesions in early stages, via transanal.
Thus, it is intended to avoid possible complications associated with conventional surgery for abdominal approach with resection of the rectum, allowing better recovery, less pain and less postoperative stay.
Moreover, being a transanal approach, one can avoid complications level of the abdominal wall, as well as complications resulting from realization of a low colorectal anastomosis.
Even so, it is essential an individualized assessment of each patient and injury by a team of surgeons with experience in colorectal surgery and minimally invasive surgery to assess the indication of this approach.
