Post-Appendectomy Fever: When to Seek Medical Attention - Surgery

Post-appendectomy, the patient experiences fever?


Hello Doctor, I underwent laparoscopic appendectomy on April 26 and was discharged home on April 30.
Since my discharge, I have experienced mild tenderness and discomfort in the right lower abdomen, and I have been taking Acetaminophen for pain relief daily.
By May 5, I felt much better and stopped taking the pain medication for the entire day.
However, on the evening of May 5, around 10 PM, I developed a fever with an axillary temperature of 37.5 degrees Celsius, and the pain in my right lower abdomen felt more intense than before.
I took one dose of Acetaminophen, and after two to three hours, my temperature returned to normal.
I would like to ask the doctor whether I should continue taking pain medication and monitor my condition, or if I should go directly to the hospital for an examination, considering that my temperature is now normal and the pain in my right lower abdomen is not too severe.

Based on your description, I would recommend that you return to the original surgical hospital for further evaluation.
Arrange for blood tests to confirm whether there is a common postoperative complication of appendicitis, such as an intra-abdominal abscess.
If the blood tests show an increase in white blood cell count or inflammatory markers, further imaging studies (such as a CT scan) may be necessary for definitive diagnosis.

More Info


After undergoing an appendectomy, it is not uncommon for patients to experience some discomfort and mild pain in the surgical area. However, the presence of fever, especially after a few days post-surgery, can be a cause for concern and warrants careful consideration.

In your case, you mentioned that you had a laparoscopic appendectomy on April 26 and were discharged on April 30. You experienced mild tenderness in the right lower abdomen, which is expected after such a procedure. However, on May 5, you developed a fever of 37.5°C (99.5°F) and noted an increase in pain in the same area. Although you managed to reduce your fever with acetaminophen, the recurrence of fever and increased pain should not be taken lightly.

Post-operative fever can arise from several causes, including:
1. Infection: This is the most common reason for fever after surgery. It could be a superficial infection at the incision site or a deeper infection such as an intra-abdominal abscess. Symptoms of infection may include increased redness, swelling, or discharge from the incision site, as well as worsening abdominal pain.

2. Intra-abdominal complications: After an appendectomy, complications such as abscess formation or bowel obstruction can occur. These conditions may present with fever, increased pain, and changes in bowel habits.

3. Respiratory issues: Sometimes, post-operative patients may develop pneumonia or other respiratory infections, especially if they have been less mobile during recovery.

4. Thromboembolic events: Deep vein thrombosis (DVT) or pulmonary embolism (PE) can also present with fever and should be considered, especially if you have risk factors for clot formation.

Given that you are experiencing a fever and increased pain, it is advisable to seek medical attention. While acetaminophen can help manage fever and discomfort temporarily, it does not address the underlying cause. Here are some steps you should consider:
- Return to your surgeon or the emergency department: It is important to have a thorough evaluation. The medical team may perform a physical examination, check for signs of infection, and possibly order imaging studies such as an ultrasound or CT scan to assess for complications like abscesses.

- Blood tests: A complete blood count (CBC) can help determine if there is an infection by checking white blood cell counts. Elevated levels can indicate an ongoing infection.

- Monitoring symptoms: Keep track of any changes in your symptoms, such as worsening pain, changes in bowel movements, or any new symptoms like nausea or vomiting.

- Avoid self-medication: While it may be tempting to continue taking pain relievers, it is crucial to consult with a healthcare provider before making any decisions regarding medication, especially if you are experiencing significant discomfort or fever.

In summary, while mild discomfort and fever can be common after surgery, the persistence of these symptoms, especially with an increase in pain, should prompt a visit to your healthcare provider. Early intervention can prevent potential complications and ensure a smoother recovery process. Always prioritize your health and do not hesitate to seek medical advice when in doubt.
