Extramoucous transversal coloplasty – new method of reconstruction after rectum resection
Abstract
Background: In patients, diagnosed with rectal cancer in lower thirds of rectum, a total mesorectal excision is warranted. The aim is to preserve of all vegetative functions as well. Because of better functional results anastomosis with J-pouch is preferred procedure. Formation of colonic J-pouch can not always be performed due to anatomic reasons. Transverse coloplasty have the same functional results and can be constructed almost always. In some studies there were more dehiscence reported in the group with transverse coloplasty, probably because of impaired vascularization. With sparing of submucous layer better vascularization can be achieved and all advantages of transverse coloplasty preserved.Methods: After preparing the patient following the principles of enhanced recovery surgery, resection of rectum by the oncologic principles is done. Colon is prepared for reconstruction and alongside of tenia the incision of muscular layer is done a few centimeters above the predicted anastomosis. The incision is 6 to 8 centimeters long. After the separation of muscular layer incision is sutured transversely. Submucous layer must not be opened or divided in order to obtained better vascularization of the terminal anastomosis and lower fecal inoculation. Postoperative treatment and follow-up is regular.Conclusions: Extramucous transverse coloplasty can obtain functions of reservoir for neorectum and improve quality of life in a same way transverse coloplasty can. With preservation of submucous layer the vascularization of anastomosis is better and therefore the rate of dehiscence lower. For final consent more randomized studies have to be performed.
