Post-Surgery Complications: Colorectal Tumor Surgery Risks - Surgery

Colorectal tumor surgery?


Hello Dr.
Ke: My mother, who is 80 years old, recently underwent surgery for a colon tumor at a hospital.
Two days after the stitches were removed, her colon protruded from the surgical site while she was preparing to use the restroom.
The attending physician explained that this occurred due to excessive straining during bowel movements.
Is this a possibility? Or could it be that the wound had not healed properly and the stitches were removed prematurely, without any instructions given about avoiding excessive straining while using the restroom? I would appreciate your clarification on this matter.
Thank you!

Hello: In response to your question, based on your description, your mother likely underwent an abdominal surgery to remove a colon tumor, rather than a procedure performed through the anus or laparoscopically.
In elderly patients, abdominal surgeries can sometimes lead to poor wound healing due to inadequate nutritional status, which indeed raises the possibility of wound dehiscence after suture removal.
This may be somewhat related to straining during bowel movements, but it is certainly not the primary cause.
If the wound healing is progressing well, such routine activities should not lead to any abnormal conditions.
As for whether the suture removal was premature, the opening of the abdominal wall wound is more closely related to the healing status of the abdominal fascia rather than the timing of suture removal for the epidermis.

Post-surgery complications, particularly following colorectal tumor surgery, can be quite serious and require careful monitoring and management. In your case, it sounds like your mother experienced a significant complication after her surgery, which is concerning. The situation you described, where a portion of the colon protrudes through the surgical site, is known as an "evisceration" and can occur for several reasons.

First, it is essential to understand that surgical wounds, especially in the abdominal area, need adequate time to heal. The healing process involves several stages, including inflammation, tissue formation, and remodeling. If the wound is not sufficiently healed, activities that increase intra-abdominal pressure, such as straining during a bowel movement, can lead to complications like evisceration.
The timing of the suture removal is also critical. Surgeons typically assess the wound's healing before deciding to remove stitches. If the stitches were removed too early, and the wound had not adequately healed, this could indeed lead to complications. It is standard practice for healthcare providers to give patients specific instructions regarding activity restrictions post-surgery, including avoiding heavy lifting or straining during bowel movements. If these instructions were not communicated effectively, it could contribute to the issue your mother faced.

In terms of the risks associated with colorectal surgery, they include but are not limited to:
1. Infection: Surgical sites can become infected, leading to complications that may require further intervention.

2. Evisceration: As you mentioned, this is when internal organs protrude through the surgical site, which is a surgical emergency.

3. Anastomotic Leak: If the surgery involved resection and reconnection of the bowel, there is a risk that the connection (anastomosis) may leak, leading to peritonitis, a severe abdominal infection.

4. Bowel Obstruction: Scar tissue (adhesions) can form after surgery, leading to blockages in the intestines.

5. Delayed Healing: Factors such as age, nutritional status, and underlying health conditions can affect how well a surgical site heals.

Given your mother's age and the nature of her surgery, her recovery should be closely monitored. If there are any signs of complications, such as increased pain, fever, or changes in bowel habits, it is crucial to seek medical attention immediately.

In conclusion, while it is possible that straining during a bowel movement could lead to evisceration, it is equally important to consider whether the surgical site was adequately healed before the stitches were removed. Clear communication from the healthcare team about post-operative care and restrictions is vital for preventing complications. If you have concerns about the care your mother received, it may be worth discussing these with her healthcare provider or seeking a second opinion. Regular follow-ups and monitoring are essential for ensuring a safe recovery after colorectal surgery.
