Treatment of Appendicitis
SurgeryAcute appendicitis is treated by surgery to remove the appendix. The operation may be performed through a standard small incision in the right lower part of the abdomen, or it may be performed using a laparoscope, which requires three to four smaller incisions. If other conditions are suspected in addition to appendicitis, they may be identified using laparoscopy. In some patients, laparoscopy is preferable to open surgery because the incision is smaller, recovery time is quicker, and less pain medication is required. The appendix is almost always removed, even if it is found to be normal. With complete removal, any later episodes of pain will not be attributed to appendicitis.
Recovery from appendectomy takes a few weeks. Doctors usually prescribe pain medication and ask patients to limit physical activity. Recovery from laparoscopic appendectomy is generally faster, but limiting strenuous activity may still be necessary for 4 to 6 weeks after surgery. Most people treated for appendicitis recover excellently and rarely need to make any changes in their diet, exercise, or lifestyle.
Antibiotics and Other TreatmentsIf the diagnosis is uncertain, people may be watched and sometimes treated with antibiotics. This approach is taken when the doctor suspects that the patient's symptoms may have a nonsurgical or medically treatable cause. If the cause of the pain is infectious, symptoms resolve with intravenous antibiotics and intravenous fluids. In general, however, appendicitis cannot be treated with antibiotics alone and will require surgery.
Occasionally the body is able to control an appendiceal perforation by forming an abscess. An abscess occurs when an infection is walled off in one part of the body. The doctor may choose to drain the abscess and leave the drain in the abscess cavity for several weeks. An appendectomy may be scheduled after the abscess is drained.
Complications of AppendicitisThe most serious complication of appendicitis is rupture. The appendix bursts or tears if appendicitis is not diagnosed quickly and goes untreated. Infants, young children, and older adults are at highest risk. A ruptured appendix can lead to peritonitis and abscess. Peritonitis is a dangerous infection that happens when bacteria and other contents of the torn appendix leak into the abdomen. In people with appendicitis, an abscess usually takes the form of a swollen mass filled with fluid and bacteria. In a few patients, complications of appendicitis can lead to organ failure and death.
