What is recommended after a colon cancer colectomy?


What is a colectomy?

A colectomy is the removal or resection of the diseased part of the colon.

It is a type of surgical intervention that is carried out as a result of a series of diseases that affect this part of the intestine.

When a colectomy can be done?

Among the main ones, we have the following:

- Colon cancer

- Precancerous polyps in the colon

- Diverticulitis

- Intestinal obstructions

- Ulcerative colitis that is not cured with medicines

- Important colon wounds

Consequences and alterations post-surgery:

Obviously the severity of the involvement is always directly proportional to the amount of tissue removed and its location.

Consequences, affections and recommendations according to the colon area extirpated

  • Partial or total colectomy

A partial or total resection of the colon temporarily affects the intestinal rhythm, especially after surgery, but depending on the amplitude and section area can be permanent.

Subtotal colectomy with ileo-rectal anastomosis affects the ileocecal valve to the rectum. It is the surgery that is non-transiently most affected in conjunction with ileostomy. This is because in the last part of the ileum bile juices and vitamin B12 are absorbed.

If it has been removed, it can not be absorbed, causing anemia, a significant increase in stool volume, a decrease in consistency, an increase in the rate of intestinal rhythm, an increase in the frequency of stools and an increase in the work performed by the kidneys in order to compensate for these losses of fluid (if the urine is darker than usual, denoting a lack of fluid intake, increased water intake must be increased). In these cases, vitamin B12 should be given intramuscularly for life.

  • Right Hemicolectomy:

The right hemicolectomy, from the ileocecal valve to the ascending part of the colon, seriously increases the intestinal rhythm and reduces the possibility of fermentation.

In that zone, the peristaltic movements are performed in the reverse direction of the rest of the intestine, in order to perform the fermentation for longer. The bile juices are not absorbed either.

Over time, the altered and increased frequency of stool frequency is normalized in most of these surgeries. Obviously, it will be easier to normalize the intestinal transit, closer to the end of the large intestine.

Even so, this normalization will cover highs and lows, less obvious after twelve months of intervention.

  • Left Hemicolectomy

The sigmoidectomy, affects the end zone of the descending colon (left), to the rectum or the anus. This resection is the one that implies a smaller affectation both at the level of absorption, and at the level of the intestinal velocity.
