persistence or recurrence of biliary or gastrointestinal symptoms after removal of the gallbladder (cholecystectomy).
These symptoms can appear immediately after surgery or months to years later.

Most common cause Retained common bile duct (CBD) stone
Stone left behind during surgery or newly formed after surgery.

Thats may lead Ascending cholangitis is a bacterial infection of the biliary tree (bile ducts), usually caused by bile duct obstruction that allows bacteria to ascend from the duodenum into the biliary system.
It’s a life-threatening emergency that requires urgent management.

Courvoisier’s Law
“In a patient with obstructive jaundice and a palpable, non-tender gallbladder, the cause is unlikely to be gallstones.”

It means:
If the gallbladder is enlarged and not painful, the obstruction is probably due to a malignant process — not gallstones.

One large public hospital reported that 47% of 721 consecutive patients with myocardial infarction presented complaining of symptoms other than chest pain. This means ED physicians must consider potential anginal-equivalent symptoms like dyspnea at rest or with exertion, nausea, light-headedness, generalized weakness, acute changes in mental status, diaphoresis, or shoulder, arm, or jaw discomfort.

Epigastric or upper abdominal discomfort, even when relieved with antacids, should raise suspicion for acute coronary syndrome, especially for patients >50 years old and those with known coronary artery disease.

Response to medications is a poor discriminator between cardiac and noncardiac chest pain.

In one study, 25% of ED patients with chest pain met diagnostic criteria for panic disorder. Conversely, 9% of the patients identified as having panic disorder were ultimately diagnosed with acute coronary syndrome on hospital discharge. This means panic disorder is at best a diagnosis of exclusion or a co-diagnosis with acute coronary syndrome (or another cause). Do not assume panic disorder in a patient with chest pain in the ED until further testing allows better risk stratification.

Classical Triad for PERFORATED PEPTIC ULCER
1. Sudden severe epigastric pain (“like a stab” or “knife-like”)
2. Board-like rigid abdomen (due to peritonitis)
3. Signs of shock — tachycardia, hypotension, sweating

Misinterpretation of ECGs (i.e., failure to detect ischemic changes that are present) occurs in up to 40% of missed acute myocardial infarc-tion cases. In addition, the initial ECG represents only a single time point in a dynamic pathophysiologic process; the diagnostic value of an ECG is improved by comparing it to a prior ECG or repeating it.

β- blockers are contraindicated in hypertension caused by cocaine, amphetamine, or related sympathomimetic drugs, since β- blockade may cause unopposed α- adrenergic activity with paradoxical hypertension and d coronary blood flow.
