Abdominal implant
Introduction
Introduction When cancer cells invade the serosa, they can fall off the surface of other organs in the abdominal cavity, causing the abdominal cavity to spread. Abdominal implant metastasis is a complex biological process. The most common sites are omentum, mesenteric, bladder rectal recess, uterine rectal recess, etc., which are more common in the pelvic Douglas nest (rectal uterus depression); Induration, can also be widely planted in the abdominal cavity to form cancerous peritonitis.
Cause
Cause
The direct spread of colorectal cancer develops in the vertical direction of the longitudinal axis of the lymphatic vessels in the intestinal wall, that is, along the circumference of the intestine and deep infiltration, and the diffusion of the parallel intestine is less in the direction of the long axis. Therefore, it rarely exceeds the upper and lower edges of the tumor. 2~3cm away. Direct spread can break through the serosa layer and invade neighboring organs such as liver, gallbladder, bladder, uterus, vagina, etc. Or cause intra-abdominal implantable dissemination.

Microscopic examination showed that the freshest planting foci showed yellow small blisters, and the most biologically active ones were large-flame hemorrhagic foci, and most of them scattered into lesions and merged into brown plaques and implanted deep.

Identification:
1. Peritoneal implantation: When the cancer cells invade the serosa, they can fall off the surface of other organs in the abdominal cavity, causing the abdominal cavity to spread. Abdominal implant metastasis is a complex biological process. The most common sites are omentum, mesenteric, bladder rectal recess, uterine rectal recess, etc., which are more common in the pelvic Douglas nest (rectal uterus depression); Induration, can also be widely planted in the abdominal cavity to form cancerous peritonitis.
2, intestinal lumen planting: colon cancer in the vicinity of the large intestine cancer is often attached to the cancer cells attached, when the mucosa is intact, the cancer cells will not grow, but if the intestinal mucosa is damaged, it can be planted in the damaged area, this It may also be one of the causes of multiple lesions in colorectal cancer.
3, medical source planting: more in the surgical process, planted in the anastomosis and abdominal wall incision. Precautions should be taken during surgery to avoid it.
