“Near-TME”: proposed standardisation of the technique for proctectomy in male patients with ulcerative colitis
Background The aim of the present study was to describe in detail an approach to proctectomy in ulcerative colitis (UC), which can be standardized; near-total mesorectal excision (near-TME), to prevent injuries to autonomic pelvic nerves and subsequent sexual dysfunction. Methods We demonstrate the technique ex vivo on a cadaver from a male patient in lithotomy position and on a sagittal section of a male pelvis. We also demonstrate the technique in vivo in two male patients diagnosed with UC, with no history of sexual dysfunction or bowel neoplasia. The study was performed at the Human Embryology and Anatomy Department. University of Valencia, Spain. Results The posterolateral dissection during a near-TME is similar to that of an oncologic TME, whereas the anterolateral is similar to that of a close rectal dissection. The near-TME technique preserves the superior hypogastric plexus, the hypogastric nerves, the nervi erigentes, the inferior hypogastric plexus, the pelvic plexus and the cavernous nerves. Conclusion The near-TME technique is the standardisation of the technique for proctectomy in male patients with ulcerative colitis. Near-TME requires experience in pelvic surgery and an exhaustive knowledge of the embryological development and of the surgical anatomy of the pelvis.
