Prevention _'s treatment of rectal cancer and surgery complication
Function and sexual dysfunction are common complications of rectal cancer operation to urinate, generally think its main reason that happens results from damaging and controlling urinating with the basin nerve of the sexual organ at present, urinate obstacle and intensity of sexual dysfunction often until lymph node clean the range directly proportional to in the pelvis at the clinic.
The basin nerve in close relation with sex function is as follows, with urinating Nerve before belonging to the orthosympathetic sacral bone and belonging to the basin viscera nerve of the parasympathetic nerve, the two participate in forming the main component of the basin clump. Orthosympathetic spreading is excited, can strengthen tense degree of sphincter, stop urinating, so the nerve is also called storing the nerve of urine before the sacral bone. Spreading that excited of parasympathetic nerve, can cause the wall smooth muscle of bladder (force the skin of urine) Shrink and the inner sphincter is relaxed, contribute to urinating, so the basin viscera nerve is also called urinating the nerve.
Sexual dysfunction regard male ejaculation and erection dysfunction as more characteristics after the operation. Ejaculation is under neural function before the sacral bone, the smooth muscle of places such as the spermatic duct,etc. shrank suddenly, the urethra after driving the seminal fluid by spermatic duct, seminal vesicle, prostate into first, and then under the function of the nerve of private parts, shrink to penetrate to finish outside the body by the body skin of sponge, so the nerve is also called penetrating spirit to pass before the sacral bone. The erection is the small arteriectasis in the penis under the neural function of basin viscera, the blood vessel in the body of sponge was congested and swollen, the volume of the penis increased and took shape, so the basin viscera nerve is also called erecting the nerve.
After the nerve, basin viscera nerve and a group of people or things of basin suffer and damage to different extent before the sacral bone, in clinic it can appear by weight - urinate, ejaculating and obstacle of erecting. Nerve by the intersection of belly and the intersection of aorta and underpart and sympathetic to do 3, 4 the intersection of waist and the intersection of waist and the intersection of viscera and nerve that section tell, participate in forming of clump in front of the sacral bone, this neural clump crosses over the branching of aorta to punish for the nerve of left and right lower abdomen, and fall along the hypogastric artery, enter the intersection of basin and clump above back pelvis, therefore and from heartbroken artery, vein under being membrane in the intersection of operation and ligature, while dissociating second form and forming the mesenterium, stripping operation should go on among peritoneum and membrane of muscle. Neural generally from side to side the branch part should be lower than branching of aorta, it is easy to distinguish that it is stripped and arrested blood carefully so long as careful.
The key of preventing the above-mentioned complication is to get hold of the level of range and stripping excised. It is only tight to excise rectum, the nerve, basin viscera nerve and basin clump before not damaging the sacral bone in the operation close to the rectum wall, urinate after the operation and the sexual dysfunction incidence is extremely low. However, rectal cancer is often soaked outside, strip and excise the small very difficult purpose to achieve the effecting a radical cure excision of the range, should person who effect a radical cure excision place main position that treat on all the time.
