METHOD FOR PERFORMING COMBINED ABDOMINOPERINEAL RESECTION WITH LAPAROSCOPIC PELVIC FLOOR REPAIR WITH LYOPHILISED DURA MATER Russian patent published in 2014 - IPC A61B17/00 

FIELD: medicine.

SUBSTANCE: method involves a laparoscopic approach and a rectum mobilisation in patients with the rectal lower ampulla cancer. The rectum is transected by means of a linear stapling apparatus 10-15 cm above an upper pole of the tumour. The second stage involves the rectum amputation from the perineum and the perineal wound closure. The laparoscopic stage is renewed. A dura mater implant 10×10 cm to 15×15 cm is inserted into the abdominal cavity. The dura mater implant is fixed by means of an endoherniostapler to the small pelvis cavity. The small pelvis cavity is drained, desufflated; trocars are removed, and the trocar wounds are closed.

EFFECT: method provides performing the abdominoperineal resection to the full extent in the rectal lower ampulla cancer with a minimum surgical wound and forming the adequate pelvic floor with using the dura mater implant, and minimising the risk of the pelvic floor hernias.
