Introduction

In general, although appendectomy is a common surgical procedure, it may still lead to certain postoperative complications, including incision infection or pain, intestinal adhesions, stump appendicitis, pelvic abscess, and gastrointestinal dysfunction. After surgery, patients should pay attention to wound care, get out of bed and move as early as possible to reduce the risk of intestinal adhesions, and maintain a light diet, avoiding overeating and binge eating.

Generally, although appendectomy is a common surgical procedure, it may still lead to certain postoperative complications, including wound infection or pain, intestinal adhesions, residual appendicitis, pelvic abscess, and bowel dysfunction. The details are as follows:

1. Wound infection or pain: If the surgical incision is not properly cared for, infection may occur, manifesting as redness, swelling, heat, and purulent discharge from the wound, accompanied by significant pain. Even after healing, some patients may experience dull or stabbing pain at the incision site due to scar tissue formation or nerve damage, especially during weather changes or fatigue, affecting local comfort.

2. Intestinal adhesions: Surgical manipulation can cause the intestines to adhere to surrounding tissues. Mild adhesions may be asymptomatic, but severe cases can impair intestinal motility, leading to abdominal pain, bloating, and even intestinal obstruction—characterized by cessation of flatus and defecation, nausea, and vomiting—requiring prompt treatment to restore bowel patency.

3. Residual appendicitis: If the remaining stump of the appendix is too long after surgery, it may develop secondary inflammation. Symptoms resemble those of acute appendicitis, such as right lower abdominal pain and nausea, with some patients also experiencing low-grade fever. Diagnosis should be confirmed through clinical evaluation followed by targeted treatment.

4. Pelvic abscess: In patients with perforated appendicitis, pus may accumulate in the pelvic cavity after surgery, forming an abscess. This presents as a sensation of heaviness and pain in the lower abdomen, tenesmus (urgent but ineffective need to defecate), and in some cases, urinary frequency and urgency. Treatment typically involves percutaneous drainage or medication to eliminate the infection.

5. Bowel dysfunction: Surgery may disrupt normal intestinal motility rhythms, resulting in temporary bowel dysfunction. Patients may experience alternating diarrhea and constipation shortly after surgery, or changes in bowel habits. These symptoms usually resolve as bowel function gradually recovers; however, if they persist, dietary adjustments or medications may be needed to improve the condition.

After appendectomy, patients should pay attention to wound care, get out of bed and move early to reduce the risk of intestinal adhesions, maintain a light diet, and avoid overeating to promote faster recovery and minimize the likelihood of complications.

Does getting anesthesia hurt during appendicitis surgery?

In general, whether anesthesia for appendectomy causes pain depends on the type of anesthesia used. Local anesthesia may cause mild discomfort, while general anesthesia usually involves no significant pain. After surgery, it is important to keep the incision clean and dry to prevent infection. Initially, patients should eat light and easily digestible foods, gradually returning to a normal diet. Appropriate physical activity can be resumed according to individual recovery progress.

Can you eat seafood after appendicitis surgery?

In general, whether seafood can be consumed after appendectomy depends on the individual patient's postoperative recovery. When eating seafood, start with a small amount and monitor for any adverse reactions such as rashes or diarrhea. Postoperative diet should follow the principle of gradual progression—beginning with liquid or semi-liquid foods and slowly transitioning to regular meals. Avoid consuming spoiled or un新鲜 seafood.

Will an appendectomy leave a scar?

In general, whether appendicitis surgery leaves a scar depends on various factors, including the surgical method, individual physical constitution, and postoperative care. If any discomfort occurs, it is recommended to seek timely medical evaluation and treatment at a正规 hospital. After surgery, keep the incision clean and dry, avoid getting it wet or scratching it, and prevent infection. Follow the doctor's instructions to change dressings regularly, and include adequate protein and vitamins in your diet.

What to do if there is an infection after appendicitis surgery

In general, the main treatments for postoperative infection after appendectomy include wound care, antibiotic therapy, drainage management, nutritional support, and symptomatic treatment. If signs of infection occur after surgery, prompt medical attention is required to prevent worsening of the condition. During the postoperative recovery period, patients should closely monitor the surgical wound and their overall condition. If symptoms such as increased redness and swelling at the incision site or persistent fever develop, medical evaluation is necessary.
