Bleeding from the stomach, the duodenum and the food pipe: emergency care, endoscopy, the varices route, radiology and surgery · Dr. Jivraj Mehta Hospital, Vasna, Ahmedabad

Vomiting blood, or passing a black tarry stool, means blood is coming from the stomach, the duodenum or the food pipe. It is an emergency.

The first hours are spent on the patient, not on the diagnosis: a drip, blood tests, blood if it is needed, and acid-lowering medicine by vein.

Most people never need an operation. A scope test within a day finds the source and treats it in the same sitting.

What vomiting blood or a black stool means

Blood from above the small bowel is digested on the way down. That is what turns a stool black, sticky and strong-smelling.

What is seenWhat it usually means
Fresh red blood in the vomit.Brisk bleeding, going on now. The most urgent of these signs.
Vomit that looks like coffee grounds.Blood that has sat in the stomach and been changed by acid.
Black, tarry, sticky stool with a strong smell.Digested blood from the stomach, duodenum or food pipe.
Red blood from below, with faintness and a fast pulse.This can still be heavy bleeding from above. It is not always a piles problem.
Only tiredness and a low haemoglobin.Slow, hidden blood loss. It needs a scope test, but not tonight.

The first hours, before any scope

Nothing is gained by rushing a half-resuscitated person to a scope. The first hour belongs to the drip, the blood tests and the airway.

  1. Two wide drips. Fluid is run in while blood is sent for grouping and cross-matching.
  2. Blood tests. Haemoglobin, urea, platelets, clotting, kidney tests and liver tests. The urea is often high in a bleed from above.
  3. The airway. Someone who is vomiting heavily, or is drowsy, may need a breathing tube first. Blood going into the lungs is one of the most preventable causes of death here.
  4. Acid-lowering medicine by vein. It settles the ulcer base and makes the scope easier. On its own it does not save a life.
  5. A dose to empty the stomach. A single injection of erythromycin before the scope clears old clot, so the endoscopist sees the source first time.
  6. A bedside score. A simple score using the urea, the haemoglobin, the pulse and the blood pressure tells us who is truly low risk.
  7. Correcting the clotting, within reason. Very thin blood is corrected. A mildly raised clotting number is not a reason to delay the scope.

Two things are deliberately not done. Tranexamic acid, often asked for, is not used in gut bleeding; a large trial found no benefit and more clots. And in a liver patient, plasma and platelets are not given to chase a number, because they add volume and push the pressure in the liver’s veins back up.

Blood: given on the patient, not on one number

Topping a person up to a normal haemoglobin is harmful. Giving less blood, later, leads to fewer re-bleeds and better survival.

SituationWhat is done
Haemoglobin around seven, otherwise stable.Transfuse, and aim for a modest target, not a normal one.
Known heart disease, or chest pain during the bleed.The threshold is raised a little. The heart needs more margin.
Bleeding visibly and heavily now.Blood is given for the loss as it happens, guided by the pulse and the blood pressure.
Thin blood from warfarin or a newer blood thinner.Reversed when the bleeding is life-threatening, with the cardiologist or haematologist involved.
Low platelets with active bleeding.Platelets are given. In liver disease they are not given to correct a figure alone.

When the scope happens, and what is done at it

A scope test within one day of arrival is the target, after the drip has done its work. Earlier than that does not help.

What the endoscopist sees in the ulcerWhat it meansTreated at the scope?
Blood spurting from a vessel.The highest risk of all. Bleeding now.Yes, with two methods together.
Blood oozing from the base.High risk.Yes, with two methods together.
A vessel visible in the base, not bleeding.High risk of starting again.Yes, with two methods together.
A clot stuck to the base.Middle risk. The clot often hides a vessel.Usually the clot is washed off, then the vessel treated.
A flat dark spot.Low risk.No. Tablets, and food can start.
A clean, pale base.Very low risk.No. Many such patients go home early.

One rule matters above the others. An injection of dilute adrenaline alone is never enough. It must be paired with heat or a clip.

  1. Injection. Dilute adrenaline is placed around the vessel. It buys a clear field, and nothing more.
  2. Heat. A probe is pressed on the vessel and the tissue is sealed shut. This is the most common second method.
  3. A clip. A small metal clip is placed across the vessel through the scope.
  4. A larger clip over the scope’s tip. For a big ulcer, a scarred base, or one that has bled again, this takes a full-thickness bite and holds better.
  5. A powder sprayed on the surface. Useful when the bleeding is diffuse and there is no single target. It washes away in a day or three, so it is a bridge and never the final answer.

After a high-risk ulcer has been sealed, acid-lowering medicine is given in high dose by vein for three days, and the patient stays in a monitored bed. That window is chosen for a reason: most second bleeds happen inside it. Two ulcer positions are the classic troublemakers. An ulcer on the back wall of the duodenum sits over a large artery, and an ulcer high on the lesser curve of the stomach sits over another. Both are flagged early to the radiologist and the surgeon.

Is it an ulcer, varices, or something else?

Almost every cause of bleeding from above is a benign one. The scope separates them in minutes, and the treatments are not interchangeable.

CauseHow it behavesWhat it needs
Peptic ulcer of the stomach or duodenum.The commonest cause. Linked to the germ H. pylori and to painkillers.Scope treatment, acid-lowering medicine, germ treatment.
Varices in the food pipe or stomach.Swollen veins caused by high pressure in the liver’s blood flow.A completely separate route. Rubber bands or glue, plus medicine.
A tear at the junction of the food pipe and stomach.Follows violent vomiting or retching. Usually settles by itself.Watching, and treatment only if it keeps bleeding.
Erosions and inflammation of the lining.Painkillers, alcohol, severe illness in intensive care.Medicine. Scope treatment is rarely needed.
Abnormal small vessels in the lining.Repeated slow bleeds, often in older people or with kidney disease.Sealing by scope, sometimes more than once.
A tumour of the stomach or food pipe.One cause among many, and not the common one. Usually a slow bleed with weight loss.Biopsy first, and a different pathway altogether.

Every ulcer in the stomach itself is biopsied at the scope, and the biopsy is repeated later if the ulcer has not healed. That discipline is not negotiable.

The separate route when the bleeding is from varices

Varices are a pressure problem in the liver, not an acid problem. Nearly every step of the first hours is different, and the order matters.

StepWhy it is done first
A drug that squeezes the gut’s blood vessels, usually terlipressin.It lowers the pressure driving the bleed. It is started on suspicion and continued for a few days.
An antibiotic, usually ceftriaxone.Not optional. In liver patients it lowers both the chance of bleeding again and the chance of dying.
A protected airway in heavy vomiting or confusion.Blood reaching the lungs is a major preventable cause of death in this group.
Careful fluid, and no plasma to chase a number.Over-filling pushes the liver pressure back up and re-opens the vein.
A scope inside about half a day.Sooner than for an ulcer, because the bleeding is faster.

At the scope the position of the vein decides the tool. Rubber bands for the food pipe, tissue glue for veins at the top of the stomach.

  1. Rubber band ligation for varices in the food pipe. The vein is sucked into a cap and a ring is fired at its base. Several are placed in one sitting.
  2. Tissue glue for the swollen veins in the dome of the stomach. The glue sets on contact with blood and plugs the vein from inside.
  3. Why not bands on a stomach vein. A band on a bulky vein there leaves a deep ulcer over a high-flow vessel, and that can bleed catastrophically.
  4. A coil placed under ultrasound guidance, with a smaller amount of glue anchored on it, where that service exists. It holds the glue locally.
  5. A plan before discharge. A beta-blocker tablet, usually carvedilol, and a booked series of banding sessions every two to four weeks until the veins are gone.

When a scope cannot stop it

A small number of bleeds defeat the scope. The order of escalation is fixed, and an operation sits at the end of it, not the middle.

  1. Repeat the scope once. A second attempt controls many re-bleeds, with less harm than going straight to theatre.
  2. Block the vessel through a catheter. The radiologist passes a fine tube from the groin artery up to the bleeding vessel and closes it. For an ulcer bleed, this is now the preferred next step where the service exists. It avoids opening the abdomen in an elderly, frail patient.
  3. A shunt inside the liver, for varices. A channel is created between two veins in the liver to drop the pressure. In a high-risk liver patient it is better placed early, within about three days, rather than after a second bleed.
  4. An operation. Reserved for failure of the scope and of the radiology route, for bleeding that cannot be kept up with, or where no radiology service is available.
If an operation is neededWhat is done
Bleeding ulcer on the back wall of the duodenum.The duodenum is opened and the artery is tied above, below and at its branch, so no feeder is left.
Bleeding ulcer in the stomach.The ulcer is cut out and sent for examination, or under-run. A larger lesion may need part of the stomach removed.
Bleeding that cannot be localised.Packing to control it, then a return to theatre or to radiology once the patient is stable.
Varices, with no shunt service reachable.A shunt operation or a devascularisation, in experienced hands. Emergency surgery here carries a high risk.

Stopping the next bleed: the germ, and the painkillers

Treating the germ H. pylori prevents more re-bleeds than any step taken in the emergency room. It is part of the treatment, not an extra.

  1. Test during the admission. A sample at the scope, or a breath or stool test.
  2. Repeat a negative test later. Active bleeding makes these tests read falsely negative. A negative result during a bleed does not settle anything.
  3. Take the full course. In India the standard first course runs fourteen days, with an acid tablet, bismuth and two antibiotics. It is used because resistance to the older short course is high here.
Blood thinner or painkillerWhat is usually advised
Low-dose aspirin taken after a heart attack or a stent.Continued, or restarted within a few days, with an acid tablet. Stopping it reflexively causes more deaths than it prevents.
Aspirin taken with no heart disease, just in case.Often stopped. The reason for it was weak.
Two antiplatelet drugs after a recent stent.Aspirin is kept. The timing of the second drug is settled with the cardiologist, never alone.
Warfarin or a newer blood thinner.Held during the bleed, and restarted once the bleeding is secure, on a date agreed with the treating physician.
Ordinary painkillers bought over the counter.Stopped. Paracetamol is the usual substitute. This is the commonest avoidable cause we see.

Risks, named in words

Most harm in a bleed comes from the body’s other illnesses and from blood reaching the lungs, not from running out of blood.

RiskWhat it means, and what prevents it
Blood going into the lungs.A chest infection, and sometimes worse. Prevented by protecting the airway early in heavy vomiting or drowsiness.
Bleeding again.Happens to a minority, mostly in the first three days. Managed by a repeat scope first, then the catheter route.
A hole made during heat treatment.Uncommon. The duodenal wall is thin. Recognised at once and dealt with by the surgeon or the radiologist.
After blocking the vessel by catheter.Dye can strain the kidneys, and a nearby vessel can be closed by mistake. Both are uncommon with a selective technique.
After an operation.A leak at the repair, a collection of pus, a wound that opens, or a return to theatre. The risk of dying rises steeply with shock, delay and other illnesses.
After glue or bands.Glue can travel to the lung, rarely. A band site can ulcerate and bleed, usually a week or two later.
After a shunt in the liver.Confusion from toxins bypassing the liver. It is treatable, and the shunt can be narrowed.

Follow-up after a bleed

A bleed is not finished when it stops. It is finished when the cause has been removed and proved gone.

WhenWhat happens
Before leaving hospital.The germ course prescribed and explained, the painkiller stopped or covered, and a date for the next scope written down.
Six to eight weeks.The breath or stool test to confirm the germ has gone, with the acid tablet stopped beforehand.
Two to three months, stomach ulcer.A repeat scope to prove the ulcer has healed, with a fresh biopsy if it has not.
Varices, every two to four weeks.Banding sessions until the veins are gone, then checks at longer intervals.
Long term.No painkillers without asking. Any return of black stools or faintness is reported the same day.

Cost, insurance and admission

A bleed costs what the pathway needs. A written estimate is given before any planned admission, procedure or special scan.

Most of this pathway is widely available and not expensive. The acid medicine, the germ course and the banding sessions are all standard. The costly end is the catheter route and the liver shunt, and the honest position is that both are concentrated in larger hospitals. We say so early, rather than looking for them at two in the morning. Dr. Jivraj Mehta Hospital, Vasna, Ahmedabad works with the major insurers and cashless options, and its office handles pre-authorisation. Bring every old scope report, every scan, the liver reports, your medicine list including painkillers, the insurance card and an ID.

Frequently asked questions

Is vomiting blood always an emergency?

Treat it as one. Even a small amount can be the first sign of a vessel that is about to bleed heavily. Go to a hospital with a scope service the same day, and do not drive yourself.

Why am I not being given more blood when my haemoglobin is low?

Because giving more makes things worse. Filling the circulation back to a normal level raises the pressure on the clot and re-opens the vessel. A modest target leads to fewer re-bleeds and better survival.

Can I keep taking my heart aspirin?

Usually yes, once the bleeding has been stopped, with an acid tablet alongside it. Stopping it out of caution causes more heart deaths than it prevents. Aspirin taken without a heart problem is a different matter and can often be stopped.

Why does a stomach ulcer have to be biopsied?

Because a stomach ulcer and an early tumour of the stomach can look the same through a scope. Only the tissue tells them apart. A second scope at about two to three months proves the ulcer has healed.

Can this happen again?

It can, and that is why the course after the bleed matters so much. Clearing the germ, confirming it has gone, and never taking painkillers unasked are what keep it from coming back.
