A transverse coloplasty was first described (by Z'gra-gen) in 1999 and facilitate the construction of a pouch anal anastomosis. The pouch is performed by making an 8-10-cm longitudinal colotomy, 4-6 cm from the distal cut end of the colon. The colotomy is made on the antimesenteric side of the colon between the taenia. Colon is then sutured transversely with 3-0 polyglycolic acid seromuscular threads similarly to the Hainecken-Mikulicz plasty. Finally end-to-end stapled anastomosis is performed with CAA stapler .
Transverse coloplasty requires less space in the pelvic area than colonic J-pouch, therefore it is technically more suitable, especially in the narrow male pelvis. Short- and long-term follow-up show similar functional results of these two types of rectal pouches .
