Appendicitis | Symptoms, Diagnosis & Laparoscopic Surgery

Appendicitis is inflammation and infection of the appendix - the most common abdominal surgical emergency in India and worldwide. It primarily affects young adults and children. Classic presentation: pain starting at the navel and shifting to the right lower abdomen, accompanied by loss of appetite, nausea, and fever. Treatment is laparoscopic appendectomy - safe, minimally invasive, and with rapid recovery.

Quick Answers

What is appendicitis? Inflammation and infection of the appendix - a finger-shaped pouch in the right lower abdomen. The most common abdominal surgical emergency.

Classic symptoms? Pain starts around the navel → shifts to right lower abdomen over 6–12 hours → loss of appetite → nausea → fever. Pain worsens with movement.

Does it need surgery? Yes - laparoscopic appendectomy is the definitive treatment. Appendicitis does not resolve on its own and progresses to perforation within 24–72 hours.

What happens if not treated? The appendix perforates - infection spreads to the entire abdomen (peritonitis). Life-threatening. Mortality is low with early surgery but significant with delayed presentation.

Recovery after surgery? Next-day discharge for non-perforated disease. Return to light activity in 1 week. Full recovery in 2 weeks. Small scars nearly invisible.

Appendicitis is one of the most common conditions requiring emergency surgery in India. The appendix - a vestigial structure with no clear function in adults - becomes obstructed, inflamed, and infected, producing a recognisable clinical syndrome. When diagnosed and treated promptly, outcomes are excellent. Delayed treatment risks perforation, peritonitis, and serious complications.

What Is the Appendix and Why Does It Get Inflamed?

The Appendix - Anatomy and Obstruction

The appendix is a 5–10 cm finger-shaped tube attached to the cecum (start of the large intestine) in the right lower abdomen. In most people, it hangs downward (retrocolic) or points toward the pelvis. Appendicitis begins when the appendix lumen is blocked - most commonly by a fecalith (hardened ball of faeces), lymphoid tissue hyperplasia (particularly in children, often after a viral infection), or rarely a tumour or foreign body. Once blocked, bacteria multiply in the stagnant appendix contents, causing increasing pressure, ischaemia of the wall, and ultimately bacterial invasion and infection.

Symptoms of Appendicitis: The Timeline

Early

Anorexia and periumbilical pain

Loss of appetite is often the first sign - the patient doesn't feel like eating. A vague, poorly localised ache develops around the navel. Mild nausea begins.

6–12h

Pain shifts to right lower abdomen

As inflammation extends to the peritoneum overlying the appendix, pain becomes precisely localised at McBurney's point in the right lower quadrant. It becomes constant - not colicky. Worsens with movement, coughing, jolting.

12–24h

Fever and worsening symptoms

Temperature rises to 38–38.5°C. WBC continues to rise. Pain intensifies. Patient appears increasingly unwell. Perforation risk rises significantly after 24 hours of symptoms.

24h+

Risk of perforation

Without surgery, the appendix perforates. Brief apparent improvement followed by spreading pain, high fever, and rigid abdomen as peritonitis develops. Life-threatening emergency.

Causes and Risk Factors

Fecalith - hardened faecal material obstructing the appendix lumen; the most common cause in adults
Lymphoid hyperplasia - swelling of lymphoid tissue in the appendix wall from viral infection (e.g., common cold, gastroenteritis); most common cause in children and young adults
Mucus plug - thick secretions blocking the appendix
Appendicular tumour - rare; appendicular carcinoid or adenocarcinoma can obstruct the lumen
Foreign body - very rare; seeds, small objects

Risk factors: Male sex (slightly higher risk), age 10–30 years (peak incidence), family history, diet low in fibre (leads to harder faeces and fecalith formation).

Seek emergency care if appendicitis symptoms are followed by:

Sudden brief improvement of pain (appendix has just ruptured) then spreading pain
Pain spreading from right lower to the whole abdomen
Abdomen becoming rigid
High fever (>39°C), rigors
Signs of septic shock - low blood pressure, rapid heart rate, confusion

Diagnosis

Clinical assessment

History and examination are the starting point. Alvarado score calculated (see When Abdominal Pain May Be Appendicitis page). Rebound tenderness, Rovsing's sign (right lower pain on pressing left lower abdomen), and psoas sign (pain on right hip extension) are specific for appendicitis.

Blood tests

WBC elevated (>10,000) with neutrophilia in >70% of appendicitis cases. CRP elevated. Normal WBC does not exclude appendicitis - particularly early in the disease.

CT scan

The most accurate investigation - sensitivity >95%. Identifies appendix diameter (>6mm = abnormal), periappendiceal fat stranding, free fluid, and complications. Performed when Alvarado score is 5–8 or clinical diagnosis is uncertain.

Ultrasound

First-line in children and pregnant women to avoid radiation. Sensitivity 70–80% - lower than CT. A normal ultrasound does not exclude appendicitis in a clinically suspicious case.

Treatment - Laparoscopic Appendectomy

Laparoscopic appendectomy is the gold standard treatment for appendicitis. It is safe, effective, and provides rapid recovery.

The procedure

3 small incisions: one 10–12mm (navel area), two 5mm (right lower and central lower abdomen)
Carbon dioxide gas inflates the abdomen to create working space
Camera and instruments inserted through the incisions
Appendix base divided with a staple or loop ligatures; appendix removed in an endobag
General anaesthesia; 30–60 minutes
Same-day or next-day discharge for uncomplicated disease

Advantages of laparoscopic over open appendectomy

Smaller scars (nearly invisible at 6 months)
Less post-operative pain
Faster return to normal activity (1 week vs 2–3 weeks)
Lower wound infection rate
Diagnostic advantage - entire abdomen and pelvis inspected for alternative diagnoses

Antibiotic treatment for appendicitis

Some studies show antibiotics alone can treat uncomplicated appendicitis in the short term - however, 30–40% recur within 5 years, requiring surgery at a potentially more complex stage. The risk of missing an appendiceal tumour (carcinoid) without surgery is also relevant. Laparoscopic appendectomy remains the standard recommendation in India for most patients.

Recovery After Laparoscopic Appendectomy

Day 1: Liquids in the morning after surgery; discharge same evening or next morning
Days 1–3: Mild incision site discomfort; oral analgesics; light walking encouraged
Week 1: Light activity; avoid heavy lifting; normal soft diet
Week 2: Return to desk work, school; increasing activity
Week 2–4: Return to physical work, exercise, and sports
Scars: Three small scars that fade to near-invisible within 6–12 months

Appendicitis in India

Appendicitis is among the most common emergency surgical conditions in India, with a very high volume of cases managed at every major surgical centre
Delayed presentation - many patients take analgesics for 24–48 hours at home before presenting to hospital - leads to a higher proportion of perforated appendicitis in India compared to centres with earlier presentation
Children in India tend to present with more advanced disease than adults - the progression from onset to perforation is faster in children (24–36 hours)
Laparoscopic appendectomy is now widely available across major cities in Gujarat including Vadodara - outcomes at experienced centres are excellent
Negative appendectomy rate (operating and finding a normal appendix) has reduced significantly with CT availability - but a "negative" appendectomy in a highly suspicious case is always preferable to allowing perforation

Frequently Asked Questions

Yes - the appendix has no essential function in adults. Life after appendectomy is completely normal. There is no long-term dietary restriction and no impact on digestion, immunity, or organ function. Modern immunological research has suggested the appendix may have a minor role in gut immunity, but its removal has no clinically significant impact on health outcomes.

The Alvarado score is a validated clinical scoring tool that assigns points to appendicitis features: pain migration (1 point), anorexia (1), nausea/vomiting (1), right lower tenderness (2), rebound tenderness (1), fever (1), elevated WBC (2), neutrophilia (1). Scores ≥7 have high probability of appendicitis and typically warrant CT scan and surgical evaluation. Scores 5–6 are indeterminate and usually require CT and observation. Low scores (1–4) can often be discharged with instructions to return if symptoms worsen.

No - once the appendix is removed, appendicitis cannot recur. The appendix is permanently absent. There are theoretical case reports of appendicitis in residual appendiceal stump (very rare), but standard appendectomy removes the entire appendix to the base, making this essentially impossible.

Appendicitis occurs in approximately 1 in 1,500 pregnancies - and is the most common non-obstetric surgical emergency during pregnancy. Diagnosis is more challenging because the appendix is displaced upward by the growing uterus, changing the pain location; nausea and anorexia are common in normal pregnancy; and WBC is physiologically elevated in pregnancy. CT or MRI is used for imaging (MRI preferred to avoid radiation). Laparoscopic appendectomy is safe in the second trimester; the decision in first and third trimesters requires specialist involvement.

Appendicitis peaks in the 10–30 age group because this age group has the highest lymphoid tissue content in the appendix. Viral infections (especially respiratory and gastrointestinal) cause reactive lymphoid hyperplasia - enlargement of the lymphoid nodules in the appendix wall - which can narrow and obstruct the lumen. This is why appendicitis often follows a viral illness in young people. In older adults, fecaliths become the more common cause.

Desi Patient Questions

Appendix operation pachhi koi diet restriction chhe?

Nahi - long-term koi dietary restriction nathi. 1st week ma light food khaao - soft foods. 2nd week thi normal Gujarati diet resume kari shakay cho. Appendix nathi hoti to digestion, immunity, ya health par koi long-term effect nathi.

Laparoscopic appendectomy ma keti scars padé chhe?

3 small scars: ek 10-12mm (navel area), biji banne 5mm (lower abdomen). 6-12 months ma nearly invisible thay chhe. Open surgery ma ek 5-7cm scar padé chhe. Laparoscopic definitely better cosmetically ane faster recovery.

Kya appendicitis fever vagar pan hoi shake?

Ha - early appendicitis ma fever absent hoi shake chhe, particularly in first 6–12 hours. Normal temperature does not exclude appendicitis. As inflammation progresses, fever typically develops. Fever absence with classic pain migration and anorexia still warrants evaluation. CT scan does not depend on fever - it assesses appendix anatomy directly.
