History of surgical obstruction jaundice pt
| Feature | Calculous (Stone) | Malignant (Cancer) | Ampullary Ca |
|---|---|---|---|
| Onset | Sudden | Insidious | Insidious |
| Character | Painful, intermittent | Painless, progressive | May be intermittent (sloughing of tumour) |
| Progression | Fluctuating | Steadily deepening | Fluctuating |
| Associated fever | Yes - Charcot's triad | Absent initially | Absent initially |
"Painful, intermittent jaundice is very much characteristic of stone in the common bile duct, whereas painless and progressively deepening jaundice is a feature of carcinoma of the head of the pancreas." - S Das Manual on Clinical Surgery, 13e
| Past History Item | Significance |
|---|---|
| Previous biliary surgery (cholecystectomy, ERCP, biliary bypass) | Benign biliary stricture, post-operative injury |
| Previous episodes of jaundice | Recurrent choledocholithiasis, haemolytic cause, viral hepatitis |
| Typhoid fever | Increases gallstone risk (carrier state) |
| Viral hepatitis (A, B, C) | Hepatic vs obstructive differential |
| Blood transfusions / IV drug use | Viral hepatitis B/C exposure |
| Alcohol history | Chronic pancreatitis, cirrhosis |
| Drug history (icterogenic drugs) | Drug-induced cholestasis |
| Haemolytic anaemia | Pre-hepatic jaundice - pigment stones |
| Pancreatitis | Pancreatic pseudocyst, chronic pancreatitis causing CBD compression |
| Abdominal trauma | Haemobilia |
| Family history of liver disease / jaundice | Hereditary conditions (Gilbert's, haemolytic anaemias) |
"The past history of relevance includes previous biliary surgery, exposure to icterogenic drugs, alcohol, viral hepatitis and haemolytic anaemia." - Pye's Surgical Handicraft, 22e
| Feature | Biliary Obstruction | Liver Disease |
|---|---|---|
| History | Abdominal pain; fever, rigors; older age; prior biliary surgery | Anorexia/malaise/myalgias (viral prodrome); exposure to hepatotoxin; family history of liver disease; blood products/injection drug use |
| Stool/Urine | Clay stools; dark urine | Variable |
| Pruritus timing | Often precedes or accompanies jaundice | Less prominent |
| History Pattern | Likely Diagnosis |
|---|---|
| Middle-aged obese female, fatty food intolerance, colicky RUQ pain + jaundice + fever | Choledocholithiasis + Cholangitis |
| Elderly male, painless progressive jaundice + weight loss + anorexia | Carcinoma of head of pancreas |
| Painless progressive jaundice, may be intermittent, periampullary mass | Carcinoma of ampulla of Vater |
| Post-cholecystectomy jaundice | Benign biliary stricture / CBD injury |
| Jaundice + recurrent upper abdominal pain + alcohol history | Chronic pancreatitis |
| Jaundice + fever + rigors (Charcot's triad) | Acute cholangitis (stones) |
| Young patient + haemolytic history + pigment stones | Pre-hepatic + obstructive jaundice |
Significant loss of weight
| Mechanism | Details |
|---|---|
| Anorexia | Cytokine-mediated appetite suppression in malignancy; dislike of fatty foods in biliary disease |
| Malabsorption / Steatorrhoea | Bile does not reach the duodenum - fat digestion impaired; pancreatic enzyme deficiency in pancreatic Ca |
| Tumour cachexia | Catabolic state driven by TNF-alpha, IL-6, and other tumour-derived factors |
| Vomiting / Nausea | Reduced caloric intake |
| Gastric outlet obstruction | Pancreatic head tumour compressing duodenum |
| Diabetes mellitus (new-onset) | Pancreatic Ca destroying islet cells - metabolic wasting |
"Anorexia and loss of weight are very common as in other carcinomas... the vast majority of patients are not diagnosed until weight loss has occurred - a sign of advanced disease." - S Das Manual on Clinical Surgery 13e; Schwartz's Principles of Surgery 11e
"The majority of patients present with pain and jaundice. On physical examination, weight loss is evident and the skin is icteric; a distended gallbladder is palpable in about one-fourth of patients." - Schwartz's Principles of Surgery 11e
| Feature | Malignant (Ca Pancreas, Cholangiocarcinoma) | Benign (Stones, Stricture) |
|---|---|---|
| Weight loss | Marked, progressive | Mild or absent |
| Jaundice | Painless, progressive | Painful, intermittent |
| Fever/rigors | Absent (early) | Present (Charcot's triad) |
| Anorexia | Prominent | Mild |
| Steatorrhoea | Present (pancreatic Ca) | Absent |
| Age | Usually >50-60 years | Any age |
| Courvoisier's gallbladder | Palpable, non-tender | Not palpable (fibrosed) |
