Appendicitis is one of the most common surgical emergencies, affecting ~250,000 Americans annually, with a lifetime risk of ~7-8%. However, there is growing recognition of chronic or recurrent appendicitis, a condition where the appendix causes intermittent or low-grade right lower quadrant pain without progressing to acute perforation. This entity accounts for an estimated ~1-1.5% of appendectomy specimens. The confusing overlap between chronic appendicitis, irritable bowel syndrome, and other causes of lower abdominal pain leads many patients to search online for answers about recurring pain in the lower right abdomen.

The Question We Asked

“For the past six months, I’ve been getting on-and-off mild pain in my lower right abdomen. It comes and goes, sometimes lasting a few hours, sometimes a day or two. It’s not severe but it’s annoying and worries me. I went to the ER once and they did blood work and a CT scan and said my appendix looked a little swollen but not enough for surgery. Could this be chronic appendicitis? Should I push for surgery?”

What Each Model Got Right

GPT-4

Strengths: GPT-4 acknowledged chronic appendicitis as a real clinical entity, correctly noting that it represents recurrent inflammation without acute perforation. It appropriately discussed the differential diagnosis, including ovarian pathology in women, mesenteric lymphadenitis, Crohn’s disease, and cecal pathology. It recommended follow-up imaging and referral to a general surgeon for evaluation, noting that elective appendectomy provides symptom relief in ~80-90% of confirmed chronic appendicitis cases.

Claude 3.5

Strengths: Claude provided the most nuanced response, explaining that chronic appendicitis is underdiagnosed because many clinicians are unfamiliar with the condition. It discussed the diagnostic criteria including recurrent right lower quadrant pain lasting weeks to months, mild inflammatory findings on imaging, and symptom resolution after appendectomy. It correctly noted that the CT findings of a mildly swollen appendix support the diagnosis and recommended a surgical consultation while also listing alternative diagnoses that should be excluded.

Gemini

Strengths: Gemini provided a clear list of differential diagnoses and practical advice about symptom tracking, including keeping a pain diary noting location, severity, triggers, and associated symptoms. It encouraged following up with a gastroenterologist if the surgeon did not feel appendectomy was indicated.

Med-PaLM 2

Strengths: Med-PaLM 2 offered detailed clinical information about the pathophysiology of chronic appendicitis, including luminal obstruction, fibrosis, and low-grade mucosal inflammation. It discussed the role of appendiceal diameter measurements on CT and the potential utility of MRI for serial monitoring without radiation exposure.

What Each Model Got Wrong or Missed

GPT-4

• Did not adequately distinguish chronic appendicitis from recurrent acute appendicitis
• Failed to discuss the antibiotics-first approach as an alternative to surgery
• Could have mentioned the psychological toll of recurring unexplained pain

Claude 3.5

• Did not discuss the antibiotics-first management option for mild appendicitis
• Could have provided more specific guidance on when to go to the ER
• Slightly overemphasized surgical intervention without discussing watchful waiting

Gemini

• Did not acknowledge chronic appendicitis as a recognized diagnosis, instead suggesting the pain was likely from another cause
• Failed to interpret the CT finding of mild appendiceal swelling in context
• Oversimplified the workup by suggesting only basic blood tests

Med-PaLM 2

• Overly technical discussion of appendiceal pathology without practical advice
• Did not provide clear guidance on the decision to pursue surgery versus continued observation
• Failed to mention the role of the patient’s symptom burden in surgical decision-making

Red Flags All Models Should Mention

• Sudden worsening of pain that becomes constant and severe, suggesting progression to acute appendicitis
• Fever, chills, or rigors accompanying abdominal pain, indicating possible infection
• Rebound tenderness or pain with movement (walking, coughing), classic signs of peritoneal irritation
• Loss of appetite combined with nausea and vomiting, the classic appendicitis triad
• Pain migrating from the periumbilical area to the right lower quadrant, the hallmark pattern of acute appendicitis

When to Trust AI vs. See a Doctor

When AI Can Help

AI can provide useful background on chronic appendicitis, help patients understand their CT results, and prepare questions for their surgical consultation. It can also help patients understand the differential diagnosis of recurrent right lower quadrant pain.

When to See a Doctor Instead

Any acute abdominal pain requires in-person evaluation, not AI consultation. The decision between surgery and observation for suspected chronic appendicitis requires examination, imaging review, and individualized risk assessment. If symptoms escalate suddenly, patients should go to the emergency department immediately.

Methodology

We submitted identical patient scenarios to GPT-4, Claude 3.5, Gemini, and Med-PaLM 2 using standardized prompting. Responses were evaluated by a panel including board-certified general surgeons and emergency medicine physicians. Scoring criteria for this AI Answers About Appendix Pain (non-acute): Model Comparison evaluation included factual accuracy against current clinical guidelines, completeness of the response, appropriate safety messaging, referral to professional care when warranted, and accessibility of language for non-specialist readers [ai-answers-appendix-pain]. Each model received the AI Answers About Appendix Pain (non-acute): Model Comparison scenario three times, and scores were averaged to account for response variability [ai-answers-appendix-pain]. Testing for the AI Answers About Appendix Pain (non-acute): Model Comparison comparison was conducted under controlled conditions [ai-answers-appendix-pain] in early 2026.

Key Takeaways

• Claude 3.5 scored highest (8.9) for acknowledging chronic appendicitis as a real condition and providing a clear path toward diagnosis and treatment
• AI models varied significantly in whether they recognized chronic appendicitis as a legitimate clinical entity
• All models appropriately recommended surgical consultation, though the specificity of that recommendation varied
• The decision to pursue appendectomy for chronic appendicitis requires balancing symptom burden against surgical risks
• Patients with recurrent right lower quadrant pain should maintain a symptom diary and seek evaluation from both a surgeon and gastroenterologist
