Management of the condition first usg was done followed by ct C/o pain abdomen

Reading File

The case is clear from the imaging:

USG: Dilated appendix (10 mm diameter) with surrounding fat stranding, appendiculoliths → Acute Appendicitis + Cystitis
CECT: Normal-sized appendix with subtle omental fat stranding in RLQ → ? Epiploic Appendagitis / Omental Panniculitis (the CT was done after USG and gives a discordant but complementary picture)

The CECT impression of "subtle omental fat stranding → ? Panniculitis" alongside the USG finding of a 10 mm appendix with appendiculoliths most likely represents acute appendicitis with early periappendiceal inflammation, with the CT potentially under-calling it (appendix may have decompressed or the 10 mm on USG is the gold standard here).

Let me search the textbooks for management.

I have sufficient information from the textbook section. Let me now provide the comprehensive management answer.

Case Summary

Patient: Ms. Swetapadma Rout, 26F, presenting with pain abdomen

Investigation	Key Findings	Impression
USG Whole Abdomen	Appendix 10 mm diameter with surrounding fat stranding, appendiculoliths	Acute Appendicitis + Cystitis
CECT Abdomen & Pelvis	Normal-sized appendix; subtle omental fat stranding RLQ; corpus luteum right ovary; minimal free fluid in POD	? Omental Panniculitis

Radiological discordance: The USG (done first) shows a dilated 10 mm appendix with appendiculoliths — the hallmark of acute appendicitis. The CECT (done later) calls the appendix "normal in size" but notes subtle omental fat stranding. This discordance likely reflects early/resolving appendicitis or a decompressed appendix on CECT, but the USG diagnosis of acute appendicitis takes clinical precedence given the appendiculoliths and 10 mm diameter.

Diagnosis: Acute Appendicitis (Uncomplicated) with Appendiculoliths

Management

1. Initial Resuscitation & Pre-operative Steps

IV access + blood investigations: CBC (leukocytosis expected), CRP, LFT, RFT, coagulation profile, blood group & cross-match
Urinalysis/urine culture (USG also showed cystitis — irregular bladder wall)
β-hCG to exclude ectopic pregnancy (26F, corpus luteum seen)
IV crystalloid resuscitation (normal saline/Ringer's lactate)
NPO status, IV antiemetics, analgesia (IV paracetamol ± opioid)
Foley catheter for urine output monitoring

2. Antibiotic Therapy

Start broad-spectrum IV antibiotics with gram-negative + anaerobic coverage immediately:

Preferred Regimens	Alternative
Piperacillin-tazobactam 4.5g IV q8h	Ceftriaxone 1g IV OD + Metronidazole 500mg IV q8h
Ampicillin-sulbactam 3g IV q6h	Cefoxitin 2g IV q6h
Imipenem-cilastatin (severe/resistant)

Common organisms: E. coli, Bacteroides fragilis, Klebsiella pneumoniae

In this young woman, narrow-spectrum regimens (ceftriaxone + metronidazole) are preferred to minimize antibiotic resistance risk — evidence shows no difference in outcomes vs. extended-spectrum agents for uncomplicated appendicitis.

For uncomplicated appendicitis → antibiotics need NOT be continued postoperatively after appendectomy.

3. Timing of Surgery

Uncomplicated appendicitis is no longer a surgical emergency requiring immediate OR
Surgery can be safely delayed up to 24 hours from presentation without increased risk of progression to complicated appendicitis (Van Dijk et al.; NSQIP data)
WSES Jerusalem 2025 Guidelines: Operate within 24 hours of presentation in adults with uncomplicated acute appendicitis
⚠️ Delay to hospital day 3 is associated with increased 30-day mortality and major complications

4. Surgical Management — Laparoscopic Appendectomy (Preferred)

Laparoscopic appendectomy is the gold standard for acute appendicitis.

Setup:

Patient supine; Foley catheter
Pneumoperitoneum via Veress needle or Hasson trocar (12–15 mmHg CO₂)
Three-port technique: umbilical 10–12 mm camera port + two 5 mm working ports (suprapubic + LIF or RIF)

Key steps:

Identify appendix at base of taenia coli
Window through mesoappendix with energy device
Divide mesoappendix (vessels controlled with LigaSure/clips)
Place two Endoloops or endostapler across base of appendix; transect
Retrieve specimen in bag through umbilical port
Irrigate/suction peritoneal cavity if soiled
Close fascia at 10+ mm ports; skin closure

Advantages of laparoscopy: less SSI, faster recovery, shorter stay, better visualization in females (pelvic pathology can be assessed — important here given corpus luteum + free fluid in POD)

5. Open Appendectomy

Indicated if: laparoscopy unavailable, conversion needed, or perforation/abscess requiring open lavage.

McBurney's incision (gridiron) or lower midline for complicated disease
Identify appendix → ligate base → purse-string suture (invagination optional)

6. Non-operative Management (Antibiotics Alone)

Now an accepted option for uncomplicated appendicitis without appendicoliths in suitable patients
However, this patient has appendiculoliths — associated with higher failure rates of antibiotic therapy (~40% at 1 year) and higher perforation risk → surgical management is strongly preferred

7. Management of Concurrent Cystitis

Urine culture before starting antibiotics
Empirical antibiotics: Nitrofurantoin 100mg BD × 5 days OR Trimethoprim-sulfamethoxazole for uncomplicated UTI
The broad-spectrum antibiotics given for appendicitis (ceftriaxone/piperacillin-tazobactam) will also cover urinary organisms — dual treatment may not be needed

8. Post-operative Care

Mobilize early (POD 1)
Resume diet when bowel sounds return
Wound care; DVT prophylaxis (LMWH)
Discharge typically 24–48 hours post laparoscopic appendectomy
Histopathology of specimen is mandatory (to exclude carcinoid tumor, mucocele)

Summary Algorithm

Diagnosis confirmed (USG: 10mm appendix + appendiculoliths)
           ↓
IV access → bloods → β-hCG → NPO → IV fluids
           ↓
Broad-spectrum IV antibiotics (ceftriaxone + metronidazole)
           ↓
Schedule laparoscopic appendectomy within 24 hours
           ↓
Post-op: no further antibiotics needed (uncomplicated)
Treat cystitis separately with urine culture-guided therapy
