Combined laparoscopic and transperineal endoscopic total pelvic exenteration for local recurrence of rectal cancer.

BACKGROUND: Transanal minimally invasive surgery is a combination of single-port surgery and transanal surgery and was initially developed as a treatment for rectal tumors. Recently, this approach has also been used for more advanced or extended pelvic surgery. METHODS: We present a surgical video of combined laparoscopic and transperineal endoscopic total pelvic exenteration performed in a male patient with recurrent rectal cancer and discuss the pros and cons of this approach. RESULTS: The operating time was 775 min and the operative blood loss was 485 ml. The pathology was recurrent adenocarcinoma invading the prostate and urethra with negative surgical margins. The postoperative course was uneventful except for a urinary tract infection that was treated with antibiotics. CONCLUSIONS: The transanal/perineal endoscopic approach may have some benefits for extended pelvic surgery for recurrent rectal cancer.

[Three-dimensional demonstration of the spinal cord artery with 64-row computed tomography].

This is a report of 2 cases, in which preoperative 3-dimentional demonstration of the spinal cord artery with 64-row computed tomography was feasible, less invasive, less time-consuming, and helpful in making an interventional strategy for complex aortic disease, resulting in no postoperative paraplegia One was a 63-year-old man, who underwent total arch replacement and a long elephant trunk method for arch and descending aortic aneurysms. The length of the long elephant trunk was so determined that it ended between the descending aortic aneurysm and the origin of the spinal cord artery. The second case was a 59-year-old man, who underwent descending thoracic aorta replacement for type B aortic dissection. During the distal anastomosis, the dissection septa were trimmed in order to perfuse the blood into the true and 2 false channels, one of which was connected to the spinal cord artery. In this report, we are not suggesting that preservation of the demonstrated spinal cord artery is enough for spinal cord protection, because it is still controversial. Further study is needed to confirm the reliability and reproducibility of our methods.
