Anal fistula, colostomy?
My father was hospitalized for a neurological issue and underwent surgery.
Postoperatively, he experienced bowel problems and has four anal fistulas, so we were advised to consider a colostomy.
It has been two weeks since the surgery, and he had not had any bowel movements through the anus until the day after the doctor removed the stent, when fresh stool was expelled.
I asked the attending physician about this, and he mentioned that he had separated the intestines, so it shouldn't be possible for stool to pass.
What could be the reason for this?

Hello: In response to your question...
Based on your description, your father's artificial anus is likely a loop colostomy.
It is not uncommon for stool to occasionally pass from the distal end in this type of colostomy.
Colostomies can be classified into complete diversion and incomplete diversion, with loop colostomy falling under the latter category.
In this type of stoma, there are proximal and distal openings, which means that stool may overflow from the proximal opening to the distal opening, resulting in stool passing from the anal canal despite having a colostomy.
As long as the amount is not significant and does not affect the underlying anal condition, no further intervention is necessary.

Understanding anal fistulas and colostomy surgery can be quite complex, especially when navigating the postoperative journey. Your father's situation, involving multiple anal fistulas and the subsequent recommendation for colostomy surgery, highlights the intricate nature of gastrointestinal health and surgical interventions.
Firstly, let's clarify what anal fistulas are. An anal fistula is an abnormal connection between the anal canal and the skin surrounding the anus. They often develop as a result of an infection in the anal glands, leading to an abscess that, when drained, can leave a tract that connects the inside of the anus to the outside skin. This condition can cause significant discomfort, pain, and complications, necessitating surgical intervention.
In your father's case, the decision to perform colostomy surgery was likely made to divert stool away from the affected area, allowing the fistulas to heal and preventing further complications. A colostomy involves creating an opening (stoma) in the abdominal wall through which stool can exit the body into a colostomy bag. This procedure can provide relief and improve the quality of life for patients suffering from severe anal or rectal conditions.
Now, regarding your father's postoperative experience, it is not uncommon for patients who have undergone colostomy surgery to experience confusion about bowel movements. After the surgery, the bowel is often rerouted, and the normal passage of stool through the rectum may be altered. The fact that your father had fresh stool passing from the rectum after the removal of the stent is indeed puzzling, especially if the surgeon indicated that the bowel was properly diverted.
Several factors could explain this phenomenon:
1. Residual Bowel Function: Depending on the extent of the surgery and the specific techniques used, there may still be some residual bowel function. If the surgeon created a temporary colostomy or if the bowel was not entirely disconnected, it is possible for stool to still pass through the rectum.
2. Stool Accumulation: If there was stool accumulation in the rectum prior to the surgery, it might have been expelled after the stent was removed. This could explain the presence of fresh stool, as it may have been retained before the surgical intervention.
3. Surgical Technique: The surgical technique employed can also influence the outcome. If the fistulas were not completely addressed or if there was any miscommunication regarding the extent of the colostomy, it could lead to unexpected bowel movements.
4. Healing Process: The body’s healing process can be unpredictable. Sometimes, the body may adapt in ways that are not anticipated by the surgical team, leading to unexpected outcomes post-surgery.
Given these possibilities, it is crucial to maintain open communication with your father's healthcare team. If there are concerns about the presence of stool passing through the rectum after colostomy surgery, it is essential to discuss these with the surgeon or a gastroenterologist. They may recommend imaging studies or further evaluations to assess the integrity of the surgical site and ensure that there are no complications, such as a malfunctioning stoma or an unaddressed fistula.
In summary, while the situation may seem alarming, it is important to approach it with a clear understanding of the surgical process and the body's healing mechanisms. Regular follow-ups with the healthcare provider will be vital in ensuring your father's recovery is on track and addressing any complications that may arise.
