Postoperative fever after appendectomy?


Hello, doctor.
My wife underwent an appendectomy for the first time, but she did not eliminate any waste, which led to the accumulation of pus in the abdominal cavity.
We then went to a second hospital where she had another surgery, and they were able to drain most of the waste and abscesses.
However, the doctor mentioned that there are still some abscesses inside her intestines that need to be expelled on their own, so we were discharged.
After discharge, the doctor prescribed antibiotics, gastric medication, and pain relievers, but every time the medication's effects start to wear off, she experiences a fever.
My wife was hospitalized for about two weeks.
Are these symptoms considered normal? The doctor said that if the situation does not improve, another surgery may be necessary to completely remove the abscesses for her to recover.
Is this approach correct? Is it normal for someone to have undergone an appendectomy twice and possibly need a third surgery? Besides taking medication, what else can she consume to help expel these abscesses more effectively? Thank you for your assistance.

The management of intra-abdominal abscesses following appendicitis surgery primarily involves drainage combined with antibiotic therapy.
The drainage methods include surgical drainage or percutaneous drainage, which will be determined by the clinician based on the distribution and morphology of the abscess.
Therefore, if surgical drainage is deemed necessary, it indicates that the effectiveness of medical treatment in this situation is limited.

Post-appendectomy fever can be a concerning complication following an appendectomy, especially when there are signs of infection or abscess formation. In your wife's case, it seems that the initial surgery did not adequately address the underlying issues, leading to the need for a second procedure to drain the abscess and any remaining infected fluid.
Fever after surgery can be attributed to several factors, including:
1. Infection: This is the most common cause of fever post-surgery. If there are residual abscesses or infections that have not been fully resolved, it can lead to persistent fever.
2. Inflammatory Response: The body’s natural response to surgery includes inflammation, which can also cause fever. This is typically more pronounced in the days immediately following surgery.

3. Pulmonary Complications: Sometimes, patients can develop pneumonia or other respiratory issues post-surgery, especially if they are less mobile.

4. Thrombophlebitis: This is inflammation of the veins, which can occur after surgery and may also lead to fever.

Given that your wife has undergone two surgeries and is still experiencing fever, it is crucial to monitor her symptoms closely. The fact that she is experiencing fever as the effects of her medications wear off suggests that there may still be an underlying infection that needs to be addressed.
Here are some considerations and recommendations:
- Follow-Up with Healthcare Provider: It is essential to maintain close communication with her healthcare provider. If the fever persists or worsens, or if she develops new symptoms (such as increased pain, swelling, or changes in bowel habits), she may need further evaluation, which could include imaging studies (like an ultrasound or CT scan) to assess for any remaining abscesses.

- Antibiotic Therapy: Ensure that she is taking the prescribed antibiotics as directed. If she continues to have fever despite being on antibiotics, her doctor may need to reassess the choice of antibiotics or consider the need for further surgical intervention.

- Hydration and Nutrition: Encourage her to stay well-hydrated and to eat a balanced diet to support her recovery. Foods rich in protein can help with healing, and adequate hydration can assist in flushing out any remaining infection.

- Pain Management: Managing her pain effectively can help her to move around more comfortably, which is important for recovery. If over-the-counter pain relievers are not sufficient, discuss with her doctor about adjusting her pain management plan.

- Rest and Activity: While it’s important for her to rest, gentle movement can help prevent complications such as blood clots. Encourage her to engage in light activities as tolerated, but she should avoid any strenuous activities until cleared by her doctor.

- Monitoring Symptoms: Keep a close eye on her symptoms. If she experiences any worsening of her condition, such as increased abdominal pain, vomiting, or changes in bowel movements, seek medical attention immediately.

In summary, while some fever can be expected after surgery, persistent fever, especially after two procedures, warrants further investigation. It is crucial to work closely with her healthcare team to ensure that any remaining infection is adequately treated and to discuss the possibility of further surgical intervention if necessary. Your wife's health and recovery are paramount, and timely medical attention can make a significant difference in her outcome.
