General Surgery
The abdomen and its contents, the acute abdomen, hernias, biliary disease, bowel, breast and endocrine surgery, and the foundation every other surgical specialty builds on.

Overview
What this specialty treats, and how it thinks.
The abdomen, and everything that presents through it.
- General surgery owns the acute abdomen: appendicitis, gallstones, obstruction, hernias and perforation, the diseases that arrive through the emergency department at 3 a.m.
- The specialty's core skill is the theatre decision: who needs an operation, who needs a scan, and who needs resuscitation before either.
- Two shared ideas run through most of its operations: the acute abdomen method, and what it takes for a bowel anastomosis to heal. Learn both once and the individual operations organise themselves.
- The rhythm is take, list, ward: overnight referrals become a morning operating list, and the afternoons belong to the post-operative abdomen and its trends.

How patients arrive
Presentations
Right lower quadrant pain
“The ED calls: 22-year-old, periumbilical pain now settled in the right iliac fossa, off food, low-grade fever.”
- The migration story is the diagnosis: visceral T10 pain at the umbilicus, then parietal pain where the appendix actually lies.
- Who needs imaging and who does not: a classic story in a young man may go to theatre on the story alone; ultrasound first in the young woman.
- The differential fans out by demographics: ovarian pathology, mesenteric adenitis, Crohn's, caecal tumours at the other end of life.
Right upper quadrant pain
“Fatty-food pain for months, now constant for 18 hours with a positive Murphy's sign and a white count of 14.”
- Place the patient on the gallstone spectrum: colic (pain alone), cholecystitis (pain plus inflammation), cholangitis (pain plus sepsis plus jaundice).
- Ultrasound answers the gallbladder; the liver panel asks whether a stone has reached the common duct.
- Timing is the modern question: index-admission cholecystectomy beats sending an inflamed gallbladder home to wait.
Distension, vomiting, absolute constipation
“Colicky central pain, a tympanitic abdomen, and a virgin abdomen is nowhere to be seen: two previous laparotomies.”
- Adhesions, hernia, malignancy: the causes in order, and the groins examined before any scan is booked.
- Drip and suck is a treatment with a timer: nasogastric decompression and fluids, with reassessment scheduled, not hoped for.
- The signs that end the trial: peritonism, rising lactate, fever, or a CT showing a closed loop. Strangulation does not wait.
The groin lump
“A lump above and medial to the pubic tubercle, there for months, now suddenly tender and irreducible.”
- Reducible and comfortable is a clinic conversation about elective repair; tender and irreducible is an emergency.
- Irreducible, obstructed, strangulated: three words in escalating order, and the examination that separates them.
- The femoral hernia rule: smaller, more medial-looking, more often in women, and far more likely to strangulate, so it is always repaired.
Haematemesis and melaena
“Coffee-ground vomiting overnight, now fresh blood, melaena on the glove, and a heart rate that outruns the blood pressure.”
- Resuscitate before you diagnose: two large cannulas, blood products by ratio, and the massive transfusion protocol has a threshold, not a mood.
- Endoscopy is both the diagnosis and usually the treatment; surgery is the plan for the bleed endoscopy cannot hold.
- The duodenal ulcer that bleeds posteriorly has eroded the gastroduodenal artery: anatomy that explains both the torrent and the operation.
