Q

A patient with chronic cholecystitis presents with intermittent N+V, bloating, constipation and generalised abdominal pain. What is the most likely cause?

How does chronic cholecystitis develop and what causes this pathology to occur?

A

gallstone ileus - usually gets stuck at ileocaecal valve, but it can also erode through the gallbladder causing a cholecystoduodenalfistula.

Q

A 42-year-old female presents to the emergency department with intermittent right upper quadrant abdominal pain for the past 3 months.

History of Present Illness:
The pain is described as sharp, colicky, and radiating to the right shoulder blade. Episodes last approximately 1–2 hours and are often triggered by fatty meals. She denies fever, chills, nausea, or vomiting during these episodes. No recent weight loss or changes in bowel habits are reported.

Past Medical History:
Hypertension (well-controlled on medication).
No prior surgeries.

Family History:
Mother with a history of gallstones.

Social History:
Non-smoker.
Rare alcohol use.

Review of Systems:
Negative for fever, jaundice, or dark urine.
No significant weight loss or anorexia.

Physical Examination:
Vital signs: BP 125/80 mmHg, HR 78 bpm, Temp 36.8°C.
Abdominal exam: Mild tenderness in the right upper quadrant without guarding or rebound tenderness. No palpable masses. Murphy’s sign negative.
No scleral icterus or jaundice.

Initial Laboratory Results:
Complete blood count (CBC): Normal.
Liver function tests (LFTs): Within normal limits.
Lipase: Normal.

Imaging:
Ultrasound of the abdomen: Gallbladder wall appears normal with no pericholecystic fluid. Multiple small echogenic foci with posterior acoustic shadowing consistent with gallstones are noted. No bile duct dilation.

Q

What is the difference between for ERCP vs MRCP?

A

ERCP: Best for cases requiring intervention (stone removal, stent placement, biopsy). However, it carries higher risk and should not be used solely for diagnosis unless therapeutic intent is expected.
MRCP: Best for non-invasive diagnosis to confirm biliary or pancreatic duct pathology. It is safer and highly sensitive but not therapeutic.

Q

When is a cholecystectomy performed in the setting of acute cholecystitis? Why?

A

performed either within 72 hrs or after 6-8 weeks when inflammation settles as the inflammation makes the surgery more difficult (layers of the inflamed organ stick to surrounding structures making it harder to separate and increased the risk of adhesions, also everything looks the same - its all inflamed)
